Possible differences in the performances of vibration-reducing gloves when used with hammers of different sizes

Protection provided by vibration-reducing gloves (VR) when used with impact tools can be considerably different from that measured following the ISO 10819 Standard. This paper investigates the transmissibility, at the palm level, of three different types of vibration-reducing gloves (air bubbles; gel; neoprene) and a working leather glove, while using 8 different models of electro-pneumatic hammers for chiseling rock in a limestone quarry plant. The capability to reduce the triaxial vibration as the average of all the tested hammers results limited: 12 % for both the gloves in gel and neoprene, and 7 % for the glove in air. The working leather glove shows a tri-axial transmissibility (Tc(T)) quite equal to the unit. Anyway, the capability to reduce vibrations is tool-dependent. Among the used hammers, the glove in air showed a Tc(T) variable from 0.71 to 1.02, the glove in gel from 0.76 to 1.01, and the glove in neoprene from 0.74 to 1.05, while for the glove in leather the transmissibility remains quite always close to the unit. Grouping the hammers in two different categories in terms of average weight and average impact energy: small-size (4.4 kg; 4 J) and middle-size (10.6 kg; 18.5 J), the average transmissibility results different: Tc(T) = 0.94 for middle-size hammers, and Tc(T) = 0.86 for small-size hammers (p-value <0.00001). This mean that VR gloves could be around 10 % more efficient when used with lightweight and small impact energy hammers. Anyway, mainly because of the relatively small number of hammers investigated, further studies are needed for confirming this result.

Evaluation of sterile glove usage on digital tactile sensitivity using the Grating Orientation Task.

Surgical glove use may be associated with a decrease in tactile sensitivity, with thicker gloves or double-gloving techniques further altering sensation. This study evaluates digital tactile sensitivity by use of a Grating Orientation Task (GOT) with multiple sterile gloving techniques (no gloves, single standard gloving, double standard gloving, orthopedic gloves, and micro-thickness gloves). Each participant performed the GOT at increasing grating widths until correctly noting orientation in ≥8 of 10 trials with multiple glove types or double-gloving technique. Glove order was randomly assigned and participants were blinded to the orientation and dome size. All gloves except micro-thickness gloves showed increased threshold sensitivity values (i.e. worse fingertip sensitivity) when compared to control (micro:control, p = 0.105, others:control, p < 0.05). Single-layer gloves showed no significant difference in sensitivity when compared to orthopedic (p = 0.06) or double-layer latex gloves (p = 0.26). Standard latex gloves decreased fingertip sensitivity when evaluated with the GOT. Double-layer and orthopedic latex gloves do not decrease sensitivity when compared with single-layer gloving. Micro-thickness gloves may provide similar tactile sensitivity to no surgical glove.

Tribological properties of MAO ceramic coatings with annulus array texture on disposable surgical gloves.

Introduction: In recent research, the expansion in the use of Mg alloys for biomedical applications has been approached by modifying their surfaces in conjunction with micro-arc oxidation (MAO) techniques which enhance their abrasion and corrosion resistance. Methods: In this study, combining laser texturing and MAO techniques to produce the dense ceramic coatings with microstructures. On the surface of the AZ31 Mg alloy, a micro-raised annulus array texture has been designed in order to increase the surface friction under liquid lubrication and to improve the operator's grip when holding the tool. For this work, the micro-morphology of the coatings was characterised, and the friction properties of the commonly used scalpel shank material 316L, the untextured surface and the textured surface were comparatively analysed against disposable surgical gloves. Results and discussion: The results show that the Laser-MAO ceramic coating grows homogenous, the porosity decreases from 14.3% to 7.8%, and the morphology after friction indicates that the coating has good wear resistance. More specifically, the average coefficient of friction (COF) of the three types of gloves coated with Laser-MAO ceramic was higher than that of the 316L and MAO ceramic coatings under the action of the annulus-integrated texture under the lubrication conditions of physiological saline and defatted sheep blood, which achieved the goal of increasing friction for the purpose of helping to prevent the problem of tool slippage from the hand.

Reduction methods for finger irradiation doses in mass disasters: A comparative study

PurposeSince many intraoral radiographs are taken in mass disasters, it is important to reduce the finger irradiation dose to the operator and caregivers in intraoral radiography. However, there is not enough reporting on finger irradiation doses when the detector is placed in the oral cavity of a corpse. The objective of this study was to examine finger irradiation doses when using detector holders and protective gloves and to compare various reduction methods. MethodsOne type of disposable and two types of protective gloves were employed in this study. The average irradiation dose was calculated by dividing the accumulated dose by the number of irradiation events for intraoral imaging of the left mandibular molar; since the dosimeter detects a cumulative dose, irradiation was continued until the dose exceeded 100 μSv. Statistical analysis was performed using one-way analysis of variance, Bonferroni test, and multiple comparisons test (α = 0.05). ResultsA significant dose reduction was observed using protective gloves (maximum: 63%, mean: 59%; p<0.01). No significant difference in the irradiation dose to the finger was observed when disposable gloves were layered on protective gloves. When protective gloves were used with the detector holder held at the end position, the radiation dose reduced by approximately 91% compared to when the detector was held directly in the oral cavity. Implementing these radioprotective measures can reduce the risks of increased radiation exposure and contamination. ConclusionsThe combined use of detector holders and protective gloves was effective in reducing the radiation exposure to the operator's fingers.

Transfer, persistence, contamination and background levels of inorganic gunshot residues

This paper summarises the available literature data for the evidential evaluation topics of transfer (196 experiments), persistence (63 time series), contamination (1515 samples), and background prevalence (2158 samples) of inorganic gunshot residues (IGSR). In-house data on IGSR transfer, and the prevalence and persistence of IGSR on different types of glove are also contributed.Combining new and previously published data in a meta-analysis, we report the following findings: The median transfer rate of IGSR was 11 % and the probability distribution of contact transfer was modelled using a Beta distribution. The half-life of IGSR on hands was estimated at 52 min. On gloves, decay followed a two-phase process with the slower process proceeding at a decreased rate compared to on hands (t1/2,slow = 77 min). The occurrence of characteristic IGSR on the hands of police officers was modelled using a generalised Pareto model (GPM). Combining the prevalence and the transfer probability models, a product probability distribution model was established. The product model estimates the probability of finding any amount of IGSR post-arrest on previously clean hands, estimating 8 % probability of non-zero transfer. Characteristic IGSR detected on the general public (1 % positives), on at-risk individuals (2 % positives), and in public places (0 % positives) showed low background levels. The likelihood of finding any amount of IGSR on the general public (at-risk included) was modelled using a GPM giving a 1.3 % probability of finding at least one, and 0.2 % probability to find more than three characteristic IGSR on the general public.

How and why do healthcare workers use gloves in two Norwegian nursing homes?

Incorrect glove use can cause cross-contamination and healthcare-associated infections. Prior research has identified reasons for this, such as lack of indication, improper changing, and poor hand hygiene post-use. Limited research has investigated the reasons behind healthcare-workers' glove usage. To develop an in-depth understanding of healthcare-worker (HCW) attitudes and perceptions of glove use and explore barriers and facilitators as well as compliance with national guidelines. A small-scale convergent-parallel mixed methods study design consisting of observations with focus group interviews (FGIs) by using the Systems Engineering Initiative for Patient Safety model (SEIPS). The study was conducted at two Norwegian municipal nursing homes in Oslo for two weeks in January-February 2023. Out of 73 observations, gloves were used in 67 episodes, not worn even if indicated in six observations, and were overused sixteen times (21.9%). Lack of hand hygiene after glove removal was observed in 36 out of 67 instances (53.7%). Two FGIs disclosed that glove usage decisions are shaped by habits, knowledge, experience, and emotions linked to patient requirements, tasks, and glove type. Double gloves were used for self-protection and efficiency. Availability of gloves was a facilitator, while poor glove quality posed a barrier. Despite HCWs' knowledge of glove guidelines, their attitudes did not consistently always ensure compliance. This study underscores the need for targeted interventions to improve hand hygiene after glove removal, urging awareness of glove overuse to reduce infections, protect HCWs' skin, and promote sustainability.

Development of Latent Fingerprints on Different Types of Gloves by Using Physical and Chemical Methods

Fingerprints are a foundation of forensic evidence collected at crime scenes. But what if the perpetrator tries to be clever and wear gloves? Does this automatically mean no fingerprints will be found? Not quite. Latex gloves abandoned at crime scenes can be potential evidence that leaves the perpetrator's hidden fingerprints behind. However, despite their potential, gloves have proven to be a tricky surface for fingerprint development. This study explores the possibility of extracting fingerprints from gloves left behind by criminals. Sweat residues, dirt, and tiny particles trapped on the glove's inner surface can transfer a latent fingerprint, even if it's smudged. This smudged print can still hold valuable clues about the perpetrator. The study aims to observe the effectiveness of fingerprint development on various glove materials: latex, nitrile, cotton, plastic, and silicone. For this, a range of physical and chemical techniques were employed to reveal these hidden prints. Specialized chemicals like ninhydrin, iodine fuming, silver nitrate, Sudan black, and gentian violet were used to make the latent prints visible. Noninvasive approaches like fingerprint powders were also used to develop latent prints on the surface of gloves. This research highlights the ingenuity of forensic science in uncovering evidence even when criminals attempt to mask their identities.

Development of soft wearable robotic gloves to prevent muscle fatigue and enhance work efficiency

This study aimed to develop wearable robotic gloves that can provide comfort to logistics and transportation workers while providing hand assistance and addressing accumulated muscle fatigue caused by repetitive manual handling tasks. Two types of gloves, rivet-type and pouch-type were developed and evaluated using the nine-hole peg test (NHPT) and grip strength tests. Results showed rivet-type gloves had better dexterity, with an 8.14% faster NHPT time, and maintained 85% grip strength compared to 80% for pouch-type gloves, even after fatigue exercises. Wearability tests were conducted by measuring clothing pressure and brainwaves. In contrast to the functional experimental results, the pouch-type gloves exhibited significant decreases in clothing pressure during actuation. According to the difference in brain waves in the frontal lobe region, the beta and gamma waves observed when wearing pouch-type gloves were lower than those of rivet-type gloves, and pouch-type gloves exhibited higher alpha-wave results than rivet-type gloves. These results imply that participants were in a comparatively relaxed state when wearing pouch-type gloves. A wearer’s evaluation survey on the overall design, function, comfort, safety, ease of use, usefulness, and use intention was conducted. In summary, the rivet-type gloves exhibited better results in hand performance while the pouch-type gloves showed advantages in wearability, suggesting a tradeoff relationship between force transmission and wearer comfort. The results of this study aimed to improve the work efficiency at logistics and transportation industry sites and help improve the welfare of workers.

Analysis of glove local microclimate properties for various glove types and fits using 3D scanning method

Due to their geometry and thermal physiology, hands are most vulnerable to cold weather injuries and loss of dexterity. Gloves are the most common for hand protection during exposure to extreme thermal and hazardous environments. Although glove microclimate properties such as area factor, air gap thickness, and contact area play a significant role in thermal protection, identifying local (at individual hand segments) glove microclimate properties is still a research gap. For the first time, the glove-microclimate properties for 16 hand segments at high spatial resolution were analyzed by employing state-of-the-art hand-held 3D scanner and post-processing techniques for different glove types. Our results clearly indicate that the glove area factor for distal phalanges is significantly higher (by 49.8 %) than that for other hand segments, which increases the heat transfer from distal phalanges. In contrast, average air gap thickness was relatively uniform across all hand segments. The glove type had a pronounced effect on glove microclimate properties, e.g., bulky and heavy cold weather protective gloves had a larger average air gap thickness and glove area factor. Regression models are also developed to estimate the glove microclimate properties from simple measurement (i.e., ease allowance). Overall, this study provides essential information for the design and development of protective gloves that can help improve safety, comfort, and dexterity. Methods and mathematical models developed in this study also contribute to facilitating extremity (e.g., hand) focused thermoregulation modeling, hazard simulation, injury prediction, ergonomic design, optimum performance (dexterity and tactility) along with thermal protection.

Lead-containing radiation-attenuating sterile gloves in simulated use: Lead transfer to sweat as an unknown risk to users

BackgroundLead protective gloves are widely used to attenuate scattered radiations during fluoroscopic-guided medical procedures, thereby reducing hand exposure to radiation. AimsTo determine whether lead-containing gloves present a risk of metal leaching onto the operator's skin, particularly due to the presence of sweat. MethodsArtificial sweat of varying acidity was introduced into two types of commercial gloves containing lead. The level of lead in the sweat was then assessed after different exposure times. Electron microscopy was used to observe the morphology of the glove layers. ResultsLead was detected in artificial sweat during each contact test on two different types of gloves. The concentration of lead increased with the acidity of the sweat, and the contact time. Gloves with a protective lining transferred less lead into sweat, but it was still present at significant levels. (i.e. few milligrams of lead per glove after one hour contact). ConclusionsFluoroscopy operators should be aware of the risk of leaching of lead ions when using lead gloves under intensive conditions, although the potential harmfulness of lead ions leached into the glove remains essentially unknown.

Contamination of Resin-Matrix Composites on Chairside Handling Using Latex or Nitrile Gloves: An In Vitro Study

The aim of this study was to evaluate the effect of different gloves and clinical environment on the contamination of resin-matrix composites for restorative dentistry. Specimens of nano-hybrid resin-matrix composite (n = 6) were divided in groups regarding the handling with (A) clinical spatula; (B) latex gloves; (C) latex or (D) nitrile gloves with human saliva; (E) latex or (F) nitrile gloves with human blood. After light curing, groups of specimens were analyzed by optical microscopy at magnification ranging from x30 up to x500 and by scanning electron microscopy at different magnification ranging from x50 up to x8000. Handling of resin-matrix composites with unpowdered nitrile gloves or clinical spatulas avoided the presence of contaminants. However, agglomerates of the resin-matrix composite itself became entrapped leading to a heterogenous morphological aspect. SEM images revealed the presence of corn-derived starch released from the powdered gloves. Also, the formation of micro-spaces (voids) occurred after handling with powdered latex gloves. Specimens handled with both type of gloves contaminated with saliva showed a conditioning layer composed of glycoproteins rolls and compounds including calcium-based chlorides, phosphates, and carbonates. Also, blood products were transferred from the contaminated gloves to the resin-matrix composites after handling. Thus, resin-matrix composite restorations are susceptible to contamination with debris from powdered gloves. Also, saliva or blood debris become adsorbed and entrapped in the resin-matrix composites during clinical handling leading to the presence of defects such macro- and micro-scale voids or contaminant agglomerates.

Evaluation of the Performance of Different Types of Radiation Protection Gloves: A Cross-sectional Study.

Radiation exposure of a practitioner's fingers is a problem in interventional radiology, and radiation protection gloves (protective gloves) can help reduce such exposure. Several types of protective gloves are commercially available from various manufacturers. In the present study, we compared the protective effects and usability of four types of protective gloves. To investigate the radiation protection effect, we placed normal surgical gloves and the four types of protective gloves on phantom hands with thermoluminescent dosimeters (TLD) attached to the fingertips and the dorsum and palms of the hands. Next, they were irradiated with x rays, and the radiation dose was measured and compared using the TLDs. In terms of usability, 42 medical staff members completed a questionnaire that included seven items, such as finger movability, tactile sensation, grip, and overall satisfaction, which were scored on a 5-point scale. Consequently, the protective effects differed between the gloves, and radiation exposure was lower by 30% to 60% with these gloves compared with surgical gloves. In terms of usability, a difference of 2 to 4 points was noted between the gloves for each questionnaire item. These results suggest that radiation protective gloves can protect the surgeon's fingers from radiation exposure without reducing work efficiency by selecting gloves according to the surgical procedure.

Sensing performance of textile strain sensors with different weave structures

Many conductive fabrics have been widely used as fabric strain sensors in recent years due to their excellent flexibility. In this study, high-tenacity polyester warp yarn and silver-coated nylon weft yarn were used to produce six types of conductive fabrics with different structures. The surface morphology of silver-coated nylon yarn was observed under a microscope, and the yarn was placed in an airtight container to test the effect of different humidity on the resistance of the yarn. DM6500 digital multimeter was used to test the resistance sensitivity, fatigue resistance, repeatability, and antistatic properties of conductive fabric samples. The results showed that the change in yarn surface material, external humidity, and strain affected the change in yarn resistance. Different weave structures affected the sensing performance of the fabric. The tighter the structure, the better the sensitivity and antistatic properties, the looser the structure, the better the fatigue resistance and repeatability. Two types of fabric and nylon gloves with different structural tightness are used to make intelligent data gloves. The results showed that both fabrics had good application prospects in limb movement detection.

The weaving art of mechanically and electronically robust hydrogel realizes multi-dimensional response of stretchable sensors

In recent years, hydrogel-based soft electronics have been developed for the application of human motion, flexible robots and foldable displays. However, most existing conductive hydrogels have low toughness, single electron conduction or ionic conduction and poor adaptability towards complex applications. In this work, we obtained the toughness fiber-like hydrogel in three steps by doping nanofillers, directional extrusion freezing, and salting out. The proposed tough fiber-like hydrogel has a rich porous structure, which is achieved by doping the hydrophilic graphene nanosheets (HGNs) into a physically cross-linking polyvinyl alcohol (PVA) gel matrix. Directional extrusion freezing and salting out effect endow fiber-like hydrogel with better orientation ultimate nominal stress (∼9.5 MPa) and nominal strain (∼2200%). Meanwhile, the abundant porous structure facilitates ion migration and greatly enhances the ionic conductivity (up to 2.8 S m −1, at f = 1 MHz) of the hydrogel. The presence of HGNs endows the fiber-like hydrogel with excellent electronic conduction properties. Moreover, the weaving strategy is proposed to fabricate fiber-like hydrogel into hydrogel fabric film, which is effective for increased safety of stress-induced deformation and crack propagation. The woven hydrogel mesh bag can lift 6 kg of watermelon and the woven hydrogel net can bear a top-down weight impact of 1 kg. We also develop a novel type of woven hydrogel glove that can monitor complex hand movement. This work will provide new insight into the design of multifunctional materials with applications on electronic skin, wearable devices, and health monitoring.

Performance-Enhancing Materials in Medical Gloves.

Medical gloves, along with masks and gowns, serve as the initial line of defense against potentially infectious microorganisms and hazardous substances in the health sector. During the COVID-19 pandemic, medical gloves played a significant role, as they were widely utilized throughout society in daily activities as a preventive measure. These products demonstrated their value as important personal protection equipment (PPE) and reaffirmed their relevance as infection prevention tools. This review describes the evolution of medical gloves since the discovery of vulcanization by Charles Goodyear in 1839, which fostered the development of this industry. Regarding the current market, a comparison of the main properties, benefits, and drawbacks of the most widespread types of sanitary gloves is presented. The most common gloves are produced from natural rubber (NR), polyisoprene (IR), acrylonitrile butadiene rubber (NBR), polychloroprene (CR), polyethylene (PE), and poly(vinyl chloride) (PVC). Furthermore, the environmental impacts of the conventional natural rubber glove manufacturing process and mitigation strategies, such as bioremediation and rubber recycling, are addressed. In order to create new medical gloves with improved properties, several biopolymers (e.g., poly(vinyl alcohol) and starch) and additives such as biodegradable fillers (e.g., cellulose and chitin), reinforcing fillers (e.g., silica and cellulose nanocrystals), and antimicrobial agents (e.g., biguanides and quaternary ammonium salts) have been evaluated. This paper covers these performance-enhancing materials and describes different innovative prototypes of gloves and coatings designed with them.

Aims: This study aimed to investigate the change of the maximum torque values applied by the dentist according to the parameters of gender,dental experience and glove type used in the tightening processes applied manually by pre-graduated and post-graduated dentists to the implant superstructure parts. Methods: 24 dentists (11 Male, 13 Female) participated in our study.Participants were instructed to tighten the implant healing screw (Straumann Dental Implant System, Waldenberg, Switzerland) placed on the digital torque measuring device(Cap torque tester series TT01; Mark10, Copiague, NY)by applying maximum force with a manual wrench.Powdered latex gloves,powderfree latex gloves and sterile surgical gloves were made available to the participants in order to imitate the mouth conditions as much as possible.Manual tightening was repeated three times in each group,with at least three minutes duration. Data were recorded digitally and statistical analysis was performed with IBS SPSS statistics 22 program.Independent sample t-test and one-way Anova analysis were used to evaluate differences between groups, followed by the post-hoc Tukey test. Results: Maximum torque value for tightening with powdered latex gloves (20.01±5.55) N, powder free latex gloves (17.27± 4.34) N and surgical gloves (20.27±6.02) N was found.In addition, we did not find a statistically significant difference in terms of gender and dental experience,which are the other parameters we investigated. Conclusion: Gender, experience and glove type do not statistically affect the maximum torque to be applied in implant superstructure applications.

The Effect of Manipulation with Different Types of Gloves on Various Mechanical properties and Setting Time of Putty-Type Silicone Impression Materials

Aim: To evaluate the effects of handling with different type of gloves on the setting time, compressive and tensile strength of putty-type silicone impression materials. Methodology: The study was conducted at COMSATS Lahore and was approved by IRB FMH College of Medicine and Dentistry. In this in-vitro study three different type of gloves (Polythene, Latex and Vinyl) and two different brands each of addition silicone (Flexceed and Elite P&amp;P) and condensation silicone (Zetaplus and Cavex) impression materials were used. These materials were divided into four different groups (A, B, C and D). Each group was subdivided into four sub-groups based on the gloves used for manipulation. Sixty samples(n=20) of two brands each of addition (Elite P&amp;PA, Flexceed B) and condensation silicones (Zetaplus C and Cavex D) were prepared and analyzed to evaluate the setting time, compressive strength and tensile strength of addition and condensation impression materials. The samples were subdivided into groups A1, B1, C1, D1 (Control), A2, B2. C2, D2 (Polythene gloves), A3, B3, C3,D3 (Vinyl gloves) and A4, B4, C4, D4(Latex) respectively. Results: There was a significant effect(p&lt;0.5) on the setting time of Elite P &amp;P when mixed with latex gloves(A4) and Flexceed when mixed with polythene(B2) and latex gloves(B4) There was significant (p&lt;0.5) effect on the setting time of Zetaplus when mixed with vinyl(C3) and latex gloves(C4). There was significant (p&lt;0.5) effect on the setting time of Cavex when mixed with polythene(D2), vinyl(D3) and latex gloves(D4). There was a significant (p&lt;0.5) effect on the tensile strength of both brand of addition and condensation silicone when mixed with polythene, vinyl and latex gloves as compared to control group. There was significant effect on the compressive strength of both brand of addition and condensation silicone except that polythene gloves don’t affect the compressive strength of one group of addition silicon B2(Flexceed) Practical implications: Dental silicone type of impression materials are widely used to fabricate different indirect restorations. Gloves are essential to control cross infection for the safety of the dentist and the patients and cannot be avoided for manipulation of these materials. Worldwide, dentists use different types of gloves to manipulate silicone impression materials. The composition and type of gloves affect the setting time and properties of addition and condensation silicones, and ultimately, it can affect and compromise the clinical outcome too. Conclusion: Latex and polythene gloves should be avoided for the manipulation of addition and condensation silicones putty impression materials due to considerable effect on the setting time. Vinyl gloves are a better choice as all others affected the mechanical properties. Keywords: Addition silicones, Condensation silicones, tensile strength, compressive strength, setting time

Investigation of materials for palm and dorsal of anti-vibration gloves for thermal comfort

The thermal comfort of a work glove affects wear compliance. This study investigates the thermal comfort of five types of anti-vibration gloves that use chloroprene rubber and spacer fabric as materials to isolate vibration. An evaluation of the fabric and material on the palm and dorsal of the glove, and a wear trial of the gloves were subsequently carried out. The results showed that the palm of the glove made of spacer fabric had higher air and water vapour permeabilities than chloroprene rubber. Using a thin mesh fabric for the dorsal of the glove resulted in a significantly lower skin temperature than using spacer fabric or chloroprene rubber during hand activity. The thermal sensation of the subjects showed no significant difference among the five glove samples. However, the glove wear comfort of the spacer fabric glove was the lowest. Recommendations for the fabric thickness and glove design are provided for developing anti-vibration gloves.

Abstract 14: Barriers to Effective Safe Handling of Chemotherapeutic Drugs Among Healthcare Workers in Vietnam: Needs Assessment by Electronic Survey

Abstract Purpose: To identify barriers and facilitators of effective safe handling of chemotherapeutic drugs among healthcare workers in hospitals across Vietnam. Methods: We used Qualtrics to design a 45-question structured questionnaire in English and Vietnamese survey to assess the safe handling of chemotherapeutic drugs. This questionnaire was distributed as an anonymous online survey through the e-mail listserv of the Vietnam Pediatric Oncology Association in August 2022. Survey instruments included years of practice, types of prior training, knowledge, personal practice, and organizational factors. Respondents were asked whether they used specific personal protective equipment (PPE) in the steps of preparation, administration, and disposal of chemotherapeutic drugs. Results: The survey was distributed to 310 healthcare workers at 14 children’s hospitals. Sixty-two healthcare workers from 13 hospitals completed the survey (response rate 20%). Among those who completed the survey, diverse occupations were represented (39 nurses, 21 physicians, and 2 pharmacists). Forty-six had received prior training in the safe handling of chemotherapeutic drugs, and 25 had longer than ten years of practice. Forty-two workers reported involvement in the administration of chemotherapy, and 17 reported wearing chemotherapy gloves (compliant group) while 25 wore other types of gloves or no gloves at all (non-compliant group). Thirty-six workers (86%) reported the availability of chemotherapy gloves, and 38 (90%) were aware that not all gloves provide the same level of protection. In the compliant group, 71% (n = 12) were aware of institutional policies at their workplaces, while only 36% of the non-compliant group (n = 9) reported awareness of the institutional policies. When stratified according to the availability of institutional policy, long years of practice were more common in the compliant group. Conclusion: Overall, respondents reported having supplies of gloves and knowledge of glove use. Those who used chemotherapy gloves were generally aware of institutional policies and had longer years of practice. The next step will involve reviewing institutional policy at each institution and studying how long years of practice influence the practice of safe handling.

Efficacy of Antivibration Gloves When Used with Electric Hammers of about 10 kg for Chiseling Limestone Rocks

The ISO Standard 10819:2013 defines the method for evaluating the performances of antivibration (AV) gloves, but when used in real fields, the protection can be dissimilar to that labeled. This paper investigates the transmissibility, at the palm level, of three different types of AV gloves (air, gel, neoprene) and an ordinary leather glove, during the use of four similar electric hammers (average weight of 10 kg, and average impact energy of 18 J), in a limestone quarry plant. As the average triaxial transmissibility for all the hammers, results show very limited benefits in reducing the vibration (6%), with no significative differences among the different gloves. The working leather glove, instead, shows a transmissibility quite equal to the unit. Anyway, results can be different for the same glove when used among the different hammers, providing in some cases 19% of protection. Some differences can be found regarding the transmissibility through the three main axes for the same type of glove: the glove in gel seems to perform better in shear than in compression. The transmissibility in compression is around 20% higher than that provided by the manufacturers of the certified gloves. The usage of specific excitation curves during laboratory tests could help in providing a more accurate estimation of the transmissibility of the gloves when used with a specific tool.
