Room temperature stimulated long-persistent phosphorescence of polyurethane/SrAl2O4: Eu2+, Dy3+ composite material for textile-based applications

Textile-based SrAl2O4(SAO): Eu2+, Dy3+ composite material offers functional, aesthetic, and safety benefits, making it a valuable innovation with diverse applications in various industries. The susceptibility of textile-based SAO: Eu2+, Dy3+ composite material is degraded with repeated washing, which can diminish its luminescent properties over time. Our major goal was to create a cloth with durable photoluminescent qualities by incorporating waterborne polyurethane (WPU) as a protective coating that could generate light constantly without a light source. Through a systematic approach involving the synthesis of photoluminescent SAO: Eu2+, Dy3+ particles and their integration into a cloth substrate with waterborne polyurethane, a durable cloth with enhanced durability, protection, and adhesion properties are achieved. Cotton fabric and a rotary screen-printing machine were used to apply a thin, translucent layer of glow-in-the-dark pigment to produce the photoluminescence characteristics of the developed cloth revealing efficient light absorption and emission behavior, with emission spectra centered around absorption wavelength between 560 nm and 880 nm, with a 500 nm emission peak, exhibiting of the presence of Eu2+ and Dy3+ activator ions. In addition, to assess the comfort of the treated cotton fabric, a fabroOmeter test was conducted, that provided insights into its overall comfort level. Furthermore, the cloth demonstrates excellent stability and longevity of photoluminescence under various environmental conditions, making it suitable for applications requiring high visibility, safety signage, decorative elements, and apparel wear. This research underscores the potential of polyurethane-enhanced photoluminescent textiles as versatile and sustainable solutions for diverse practical applications.

Do red and yellow flags indicate a danger zone?: Exploring Japanese university students’ beach safety behaviour and their perceptions of Australian beach safety signage

BackgroundCoastal drowning is a tragic regular occurrence in Australia, and in the decade 2012–2022, 455 overseas-born beachgoers drowned. Being one of the top five countries of international visitors who drown, Japanese tourists are an at-risk group. This study investigates Japanese university students’ knowledge of beach safety and their perceptions of Australian beach safety signage. MethodsThe present study conducted an online survey with 152 university students in Japan, comprising both closed and open questions. Although the survey was in Japanese, the signage terms used in the survey were in English as used in Australia. Descriptive analysis was conducted on the statistical data via SPSS and deductive thematic analysis was conducted on the open responses using Nvivo. Results90 % of them planned to visit beaches and 64 % would enter the water when or if visiting Australia. However, 60 % interpreted the safer supervised zone denoted by red and yellow flags as signifying a danger zone. Regardless of their English proficiency, almost none fully understood terms commonly used on safety and warning signs such as submerged objects, shore dump, shore break and rip currents, and 60 % of them didn’t know the Japanese term of rip currents, riganryuu. Visual icons were understood much better than these English terms. So what?This study explored a specific (i.e. Japanese) cultural perception and understanding of Australian beach signs beyond the scope of CALD communities. Future studies should continue exploring those of other cultures so Australian beach signs can be revised and improved based on scientific evidence.

Implementation of Wayfinding Signage in Public Hospitals and Its Evaluation Towards Quality Improvement.

The study aims to evaluate the multi-lingual signage system in the hospital and recommend suggestions. Wayfinding or the signage work was undertaken as a Total Quality Management (TQM) Project in the study setting, conducted over 36 months. The effectiveness of the signage system was evaluated using a questionnaire-based survey among the patients, attendants, and other visitors. Color-coded multilingual signage installed in the hospital block and its surrounding areas included the naming of various areas, way-finding, and safety signage. The most difficult areas to find were ICUs (35.6%), OT (31.1%), and laboratories (31.1%). Additionally, 98% of the participants could reach their desired destination but had to double-check with the staff. It was evident from the study that hospital signage plays a crucial role in hospitals by improving wayfinding, enhancing the patient experience, and promoting safety and emergency preparedness. Signage also indirectly contributes to better patient care. In large teaching hospitals, human assistance is also necessary for wayfinding.

Assessing the integration between motorised and non-motorised transport systems: experiences of the Ekurhuleni Municipality, South Africa

ABSTRACT South Africa is considered an economically progressive country, meaning it is slowly exiting the third world and transitioning towards the developing world. With this comes many challenges, some rooted in transportation. Around 80% of South Africans solely rely on public transportation (PT) and are dependent on private minibus taxis. There is little knowledge and evidence on the fluidity and integration of motorised transport systems with non-motorised transport (NMT) in South Africa. Consequently, this work assessed the implementation of NMT and PT in Ekurhuleni. The study adopted a case study research design by analysing the Harambee BRT through a qualitative approach using desktop studies and semi-structured interviews with key informants involved in the project. The work identified five aspects of accessibility (application of the inclusive cities paradigm), safety (sufficient lighting, signage and frequent patrolling by law enforcement), infrastructure (Information and Communications Technology (ICT), walkways, pedestrian bridges, dedicated bus lanes, paving, and tact tiles, universal design principles and an Ekucard system), sustainability (promoting healthier lifestyles and the cost effectiveness of the transport system) and public involvement as the core elements which created a model that needs to be implemented in future projects in order to effectively integrate NMT and PT.

Enhanced Road Safety with Photoluminescent Pedestrian Crossings in Urban Contexts

The safety of roads in urban areas is a major concern for governments, demanding innovative solutions to enhance pedestrian safety. This paper introduces a novel approach to crosswalks by integrating resin with photoluminescent additives, offering a significant boost to road safety. A thorough methodology was employed to assess its effectiveness, covering mechanical, lighting, and vibroacoustic aspects, alongside a photogrammetric analysis of real-world experiments. The material exhibited noteworthy mechanical properties, displaying consistent tensile strength, load capacity, and strain values with a remarkable Shore A hardness. After 20 min, luminance values peaked at 68 mcd/m2, surpassing standard vehicle headlights at 100 m. Additionally, vibroacoustic analysis highlighted a noticeable relationship between vehicle speed and sound bandwidth, indicating the system’s potential to alert pedestrians. Tests revealed that the proposed system significantly decreased the average vehicle speed by 36.96% compared to conventional crosswalks, with a 27.80% reduction when drivers yielded to pedestrians. Furthermore, a survey involving 35 participants, focusing on the knowledge of road safety regulations, behavior, signage, and visibility, found positive results regarding accident reduction. The estimations indicate potential decreases of 26.26% in injuries and 35.4% in fatalities due to improved road conditions, 26.58% in injuries and 53.16% in fatalities resulting from reduced average speeds, and 52.56% in injuries and 79.91% in fatalities through enhanced road education. This underscores the multifaceted impact of the system on urban road safety.

Assessing Visitor Satisfaction with Facilities in Sarawak’s Totally Protected Areas: A Study of Bako and Niah National Parks

This study examines the level of visitors’ satisfaction with the facilities within selected totally protected areas (TPAs) in Sarawak. For this study, the national parks chosen are Bako National Park, Kuching, and Niah National Park. The visitors’ satisfaction level with the available facilities within the studied TPAs was assessed based on their feedback on the information displayed at the respective TPAs, the hygiene of the facilities available in the TPAs, and the signage (for safety measures) in the TPAs which is based on the Likert scale. The study uses three consecutive years of data from the customer satisfaction level report obtained from Sarawak Forestry Corporation (SFC). The result of this study reflects the visitors’ opinions on their expectations of the TPAs’ facilities. It was found that the visitors are satisfied with all three components, with room for improvement. They are most satisfied with the safety signage, followed by the information displayed and the hygiene aspect. This study will aid the management in managing the TPAs in the future to plan and decide what are facilities to be provided to the visitors and how those facilities can attract more visitors to uplift the TPA’s image.

Children’s Understanding of Public Safety Signage: A Scoping Review

Objective: This study aims to provides a scoping review of papers published before 30 July 2023 that explore the level of development of public safety signs design among children. Descriptive analyses were performed on 28 articles. Method: Because the review question is comprehensive, we found the scoping review to be the most appropriate way to answer this question. In order to ensure clarity and transparency, and to avoid adverse and poor reporting, We conducted our scoping review based on the 2020 PRISMA Checklist. Result: Since cultural background and signage category can also affect signage comprehension, separate studies are required by country, region, and signage type. The types of signage and countries in the current related research are relatively scattered, and there is no specific classification of public safety signage types. Most of them are safety signs in specific scenarios, such as trains and swimming pools. At the same time, the research areas are mostly concentrated in the UK in Europe, Hong Kong and Indonesia in Asia. Conclusion: These data could provide stronger evidence to identify and establish pathways to improve children’s understanding of public safety signage.

What is a shore dump?: Exploring Australian university students’ beach safety knowledge and their perceptions of Australian beach safety signage

BackgroundOn average 122 coastal drownings deaths are recorded in Australia every year. Typically, young adult beachgoers (15–34 years old), many of whom were born overseas, account for 25 % of these fatalities. This study identifies university students as appropriate subjects for investigating typical interpretations of beach safety messages and signage among this high-risk demographic. MethodsThis study involved an online survey of Australian university students (domestic: n = 136 international: n = 84). The survey comprised both closed and open-ended questions about beach safety terms and signage. Participants were recruited through university newsletters, course announcements, social media, and at beach safety workshops. Data were analysed with SPSS for descriptive analyses and Pearson Chi-Square to test for statistical differences between domestic and international students. ResultsOver 55% of domestic and over 75% of international students did not understand the common safety terms shore dump and shore break and approximately half of both groups misunderstood the sign, always swim between the flags, believing that surfers should also stay between the flags. Concerningly, 21% of international students perceived this meant that beachgoers who don’t or can’t swim need to stay outside the flags. So what?Existing beach safety signage is not as effective as authorities assume due to linguistic and translation challenges. Some terms are improperly translated into Japanese and Chinese in the current search on Google Translate. Such linguistic issues must be addressed so as to improve the delivery of coastal safety messages.

Identifying Risks for Overseas-Born Beachgoers and Suggesting Future Preventative Strategies: A Qualitative Study Based on Interviews with 20 Lifesavers from Australian Tourist Beaches

While Australia sees a high proportion of coastal drownings involving overseas-born beachgoers every year, it should not be forgotten that professional lifeguards and surf lifesavers carry out about 11,000 rescues and 1,800,000 preventative actions every year. Given these figures, lifeguards and surf lifesavers would be assumed to have ways of identifying overseas-born beachgoers who are not familiar with Australian beaches and to take special precautions in relation to them. This study aims to explore the ways by which surf lifesavers are able to identify overseas-born beachgoers who have no or little understanding of Australian beaches, and identify the surf lifesavers??? perceptions as to the effectiveness of currently available public beach safety signage, as well as educational messages communicated by the popular TV show, Bondi Rescue. One-on-one in-depth interviews were carried out with 20 lifesavers from three popular Australian tourist beaches???Bondi and Tamarama beaches in Sydney, and Glenelg beach in Adelaide. The semistructured interviews were conducted using a fixed list of questions, and a code analysis was conducted employing the program NVivo 12 (version 12.70). Based on the interview data, surf lifesavers identified a number of characteristics that suggested a lack of familiarity with Australian beaches and differentiated overseas-born beachgoers from regular beachgoers, including wearing jeans near water, particular ways of approaching the water, and the use of inflatable toys. More than half of the lifesavers said that in general beachgoers were more likely to swim outside the flags, but some said that beachgoers stay between the flags because professional lifeguards and surf lifesavers enforce this regulation. Many lifesavers cast doubts on the effectiveness of public signage, and a majority singled out the popular TV show Bondi Rescue as a powerful tool for revealing the real dangers of Australian beaches. One interview, however, warned that Bondi Rescue might lead to the misunderstanding that ???all??? Australian beaches are patrolled and, therefore, ???safe.??? It is important to address safety issues such as the fact that wearing heavy clothing and using inflatable toys can cause problems on Australian beaches with dangerous waves and rip currents. Effective ways of delivering safety messages to the public, especially to overseas-born beachgoers, still need to be developed.

Less is better: Insight into the concentration dependency of the photoreduction of Eu3+ in Ba2SiO4

Photoinduced electron transfer processes in luminescent materials drive numerous applications like medical imaging, ionizing radiation dosimetry and safety signage. However, the concentration dependency of the photoreduction of the dopants during this process is still poorly understood. Here, optical spectroscopy and electron paramagnetic resonance (EPR) experiments are systematically performed to reveal the doping concentration-dependent photoreduction behavior in Ba2-xEuxSiO4 where a fraction of the Eu3+ dopants can be reduced to Eu2+ upon irradiation with X-rays. EPR measurements show that the conversion ratio of Eu3+→Eu2+ decreases with increasing concentration at the same irradiation dose, resulting in the concentration dependency of the photoreduction behavior in Ba2-xEuxSiO4. Optical spectroscopy measurements show that although the incorporated Eu3+ ions occupy at least three crystallographic sites, Eu3+ can only be photoreduced on one of these sites. Meanwhile, the relative occupancy of this photoreducible site decreases as the doping concentration increases. The combination of these two factors might be responsible for the decreased conversion ratio of Eu3+→Eu2+ as the doping concentration increases. These findings provide insights into the photoreduction of dopants in luminescent materials and can facilitate the exploration of this functional behavior for advanced devices.

Assessing Physical Attributes Associated with Implementation of Risk Management Practices among Small Strawberry Farms

Fresh strawberries are susceptible to contamination with foodborne pathogens, illustrating the importance of on-farm risk management practices (RMP). Understanding context is necessary for successful implementation of RMP, highlighting the importance of characterizing physical attributes (PA) associated with RMP. We determined the PA associated with implementation of eight RMP on 20 small (≤ 2 acres; 8,094 m2) strawberry farms in the southeastern United States. Descriptive statistics were performed to determine frequency of PA across farms. PA scores, presence or absence of observed PA expressed as a percentage, were calculated for each of the eight RMP. All 20 (100%) farms used plasticulture to grow strawberries. All (100%) used drip irrigation systems, and 19 (95%) had an adequate number of bathrooms and handwashing stations. Nearly all (95%) did not have a body fluid spill kit. Sixteen (80%) farms used groundwater or surface water for irrigation, with five (31%) treating the water and eight (50%) testing the microbiological quality of irrigation water. PA scores ranged from 55 to 90%, with the highest (90%) for animal control and the lowest (55%) for food safety signage. These findings can inform strawberry-specific safety interventions aimed to increase RMP implementation. More broadly, this represents another approach to informing commodity-specific training needs.

Persistent Luminescence in Strontium Aluminate: A Roadmap to a Brighter Future

AbstractGlow‐in‐the‐dark materials have been around for a long time. While formerly materials had to be mixed with radioactive elements to achieve a sufficiently long and bright afterglow, these have now been replaced by much safer alternatives. Notably strontium aluminate, SrAl2O4, doped with europium and dysprosium, has been discovered over two decades ago and since then the phosphor has transcended its popular use in watch dials, safety signage, or toys with more niche applications such as stress sensing, photocatalysis, medical imaging, or flicker‐free light‐emitting diodes. A lot of research efforts are focused on further improving the storage capacity of SrAl2O4:Eu2+,Dy3+, including in nanosized particles, and on finding the underlying physical mechanism to fully explain the afterglow in this material and related compounds. Here an overview of the most important results from the research on SrAl2O4:Eu2+,Dy3+ is presented and different models and the underlying physics are discussed to explain the trapping mechanism at play in these materials.

Exploring international beachgoers’ perceptions of safety signage on Australian beaches

Background136 coastal drowning fatalities in Australia were reported in 2020–2021,almost half of which were overseas-born beachgoers. In light of these statistics, this study explores how beachgoers, including overseas-born beachgoers, see and interpret current existing beach safety signage at Bondi beach in Sydney, Australia. MethodsSurveys of beachgoers at Bondi Beach were collected over 10 days between February 8 and March 21. Surveys comprised closed responses with multiple choices. The data were analysed via SPSS for descriptive analysis for independence, and the Pearson Chi-Square test for the significance of the difference between the Australian and overseas-born beachgoers. Results167 survey responses (52 Australian citizens and 116 overseas-born beachgoers) were analysed. Of the overseas visitors and residents, 30.2% believe that swimming between the flags means only that people “perceived to be good swimmers” were allowed to be between the flags. About 50% of the Australian and international beachgoers believe that no flags = no swim means that when the flags are not displayed they cannot swim but can still go into the water. On top of these results, other terms commonly used in beach signage such as shore dump and high surf are understood by only less than 30% of overseas-born beachgoers. ConclusionThese results suggest that at least some of the beach safety signs are not interpreted correctly either by overseas-born or Australian beachgoers.Learning Outcomes: This study suggests a number of linguistic strategies to improve the clarity of nomenclature.

Beach management policy analysis concerning safety flag systems in Northern Spain

The aim of this paper is to analyse the meaning of beach safety flags and their management along the Northern Spanish coast. There are more than 1000 small beaches, which are often in high demand by tourism during the summer season. To carry out the research, most of main beaches have been visited to observe and analyse the meaning of all the safety flags and their correct use depending on the oceanographic and meteorological conditions. The influence of the beach safety management and regulations on the use of beach safety signage has been also analysed. The results show that safety flag systems differ even between very close beaches where safety management is in the hands of different local governments. Outdated and local legal framework and the absence of an agreed system between the different organizations that provide lifeguarding services seem to be behind this lack of uniformity. A specific guide for beach safety flags and signage within a national safety beach plan agreed by all the autonomic or provincial governments may be a solution.

Color-tunable photoluminescence and persistent luminescence in a single LiYGeO4:Tb3+ phosphor

Persistent luminescence (PerL) phosphors have been widely applied in many advanced applications in the field of emergency lighting, safety signage, and ornaments. Recently, the PerL phosphors based on germanates have attracted great attention owing to their excellent PerL performance. However, the design and development of excellent germanates-based PerL materials with full spectral emissions remain challenging due to the lack of color-tunable PerL, especially in the blue and green regions (400–600 nm). Herein, we develop a new type of Tb3+-activated LiYGeO4 PerL phosphor with real-time adjusting the photoluminescence (PL) and PerL color, which can be effectively excited by a 254 UV light. Both blue and green PerL are realized simultaneously in a single phosphor. When LiYGeO4:Tb3+ doped with lower concentrations of Tb3+ ions, phosphors emit blue PL and PerL. With increasing Tb3+ concentration, the PL and PerL colors of LiYGeO4:Tb3+ PerL phosphor are gradually regulated from blue to green. Besides, LiYGeO4:Tb3+ exhibits temperature-dependent luminescence property, whose PL and PerL colors can also be successively widely tuned by various temperature. This stable and tunable color in real-time PL and PerL property promote the as-designed LiYGeO4:Tb3+ phosphor to have potential applications in advanced anti-counterfeiting and display devices.

Assessment of Markets Fire Emergency Preparedness in Tanzania A Case Study of 6 Markets in Ilala City Council -Dares Salaam

This study is intended to assess fire emergency preparedness in public and private markets in Dar es Salaam Region by measuring the specific market preparedness in fire emergency policies, fire safety equipment, signage and infrastructure, fire fighting knowledge and fire preparedness plans, and acknowledging areas of improvements. The study was comparative and adopted mixed approach design implying both quantitative and qualitative methods. Primary data were collected using questionnaires, semi-structured interview and observation. Secondary data were obtained reviewing published dissertations, articles, journals, textbooks and documents from the website. A total sample of 87 respondents from public markets were selected for the study. Quantitative data was analysed by using descriptive statistics with the help of SPSS. Qualitative data was analysed by using content analysis. The use of graphs and charts was encouraged to facilitate data presentation. The findings showed that fire emergency preparedness was good in private Markets compared to public market. The study revealed that both public and private markets had awareness on firefighting activities. However, public market did not offer much trainings compared to private markets which made majority of the respondents to have less knowledge on firefighting. Also, public markets lacked fire emergency policies, plans and some of firefighting equipment compared to private markets. The study recommended that markets should have fire emergency preparedness plans, policies, sufficient equipment, signage and infrastructure and monitoring and evaluation programs. Also separate fire preparedness budget and creation of awareness programs via different communication media to improve emergency preparedness

Room Temperature Phosphorescence of Chlorine Doped Carbon Nitride Dots.

Metal free room temperature phosphorescent materials have been the subject of considerable attention due to their potential applications in optoelectronic devices sensing, and security and safety signage. This study discusses how efficient fluorescent and phosphorescent chlorine doped carbon nitride dots (Cl-CNDs) were prepared by thermal treatment of guanidine hydrochloride. The Cl-CNDs prepared were characterized by field emission scanning electron microscope, dynamic light scattering, PXRD, EDX, Thermo gravimetric analysis, FT-IR, and UV-Visible spectroscopy. The Cl-CNDs exhibit a long phosphorescence lifetime of 657 ms and the phosphorescence quantum yield was found to be 2.32% upon being excited at 360 nm in ambient conditions. Formation of compact coreparticles via condensation along with hydrogen bonding of Cl-CNDs by its functional groups facilitate intersystem crossing and stabilizes the triplet states, favoring room temperature phosphorescence. The cost effective preparation and tunable optical properties of Cl-CNDs may find applications in security encryption and optoelectronic devices.

Characteristics and beach safety knowledge of beachgoers on unpatrolled surf beaches in Australia

Abstract. The majority of drowning deaths on Australian beaches occur significant distances away from lifeguard services. This study uses results of 459 surveys of beachgoers at five beaches unpatrolled by lifeguards in New South Wales, Australia, to improve understanding of who visits these beaches and why, and to identify risk factors associated with their beach safety knowledge and behaviour. Many unpatrolled beach users were infrequent beachgoers (64.9 %) with poor rip current hazard identification skills, who did not observe safety signage that was present, and yet intended to enter the water to swim (85.6 %) despite being aware that no lifeguards were present. The survey found that the main reasons why beachgoers visited unpatrolled beaches were because they were conveniently close to their holiday accommodation, or they represented a quieter location away from crowds. Future beach safety interventions in Australia need to extend beyond the standard “swim between the flags” message in recognition that many Australian beaches will remain unpatrolled, yet still frequented, for the foreseeable future. Future beach safety interventions for unpatrolled beaches should be tailored towards the varied demographic groups of beach users.

A survey‐based study concerning public comprehension of two‐component EXIT/NO‐EXIT signage concepts

SummaryEmergency signage conveys exit route information enabling occupants to identify and utilise emergency exits during evacuation. However, it has been frequently demonstrated that static signs are insufficient to attract people's attention. Previous incidents also demonstrate that if exit routes and exits become compromised by the incident, static signs are unable to adapt as required. A goal of the signage industry is to address these limitations while maintaining the clear and unambiguous information conveyed. A signage concept addressing these limitations incorporating a pair of linked adjacent signs, a standard EXIT sign and a text‐based ‘NO‐EXIT’ sign, is proposed. At any one time, only one sign is activated, displaying either EXIT or NO‐EXIT. The active sign can also flash to improve detectability. To assess whether this concept was acceptable, an online international survey, based on the ANSI Z535.3 comprehension test methodology was conducted. The results demonstrate that this novel concept fails to meet the acceptance criteria for safety signs, and as a result, the concept was abandoned by the manufacturer. This study also highlights the importance of conducting comprehension tests for any new safety signage design and the need for composing guidelines for design and application of dynamic signs.

Occupational Contact Dermatitis in Employees of Large-Scale Narcotic Crop Farms of Ethiopia: Prevalence and Risk Factors. A Self-Reported Study Using the Nordic Occupational Skin Questionnaire.

Background:Occupational skin diseases are the second leading occupational disease, accounting for almost 25% of all missed workdays. Occupational contact dermatitis (OCD) accounts for 70% to 90% of all skin disorders in the workplace. Only a few occupational epidemiology studies have looked into the prevalence and risk factors of occupation-induced dermatitis among narcotic crop farm workers around the world. Related studies in Ethiopia are even fewer.Methods:A cross-sectional survey was conducted in the Dirashe district of Southern Ethiopia from March 23 to April 12, 2021. Data was collected using a standardized interviewer-administered questionnaire. The history of contact dermatitis was determined using the standardized Nordic Occupational Skin Questionnaire version 2002 (NOSQ-2002). A total of 578 farm laborers took part in the study, which was conducted using a systematic random sampling. Descriptive statistics and multivariable regression were used to characterize the data and identify factors associated with occupational contact dermatitis.Result:The prevalence of self-reported occupational contact dermatitis in the past 12 months among workers of large-scale Khat farms was (AOR: 67.80%, 95% CI [61.00, 76.23]). In the multivariable regression, being older (AOR: 5.51, 95% CI [1.79, 7.24]), working as a bundle binder (AOR: 5.74, 95% CI [2.12, 15.55]), not wearing personal protective equipment (PPE) (AOR: 2.50, 95% CI [1.64, 3.81]), and having poor knowledge of pesticides use, storage, and disposal methods (AOR: 2.50, 95% CI [1.64, 3.81]) were associated with occupational contact dermatitis.Conclusion:Contact dermatitis caused by work is very common among Khat farm laborers. Measures to promote safe practices and reduce exposure to hazards, such as removing expired and/or banned chemicals, purchasing alternative pesticides that meet legislative requirements, job rotation and routine training of staff on safe practices, increasing safety signage, and performing risk assessments, as well as improving the quantity and quality of institutional protective equipment supplies may thus contribute to the enhancement of safe work practices.
