Clinical features and risk factors for colorectal gas explosion during digestive endoscopy and surgery: a systematic review.

Colorectal gas explosion (CGE) is an exceptional but potentially fatal complication of digestive endoscopy or surgery. The role played by bowel preparations and endoscopic or surgical devices in the risk of CGE is still unclear. We conducted a systematic review of the literature to identify risk factors for CGE. We conducted a comprehensive literature search of multiple databases from inception to September 16, 2024 including all reports of CGE according to a systematic review protocol preregistered on the PROSPERO database (CRD42023455049). Additionally, we analyzed all trials that measured explosive gas levels after different bowel preparation strategies. Twenty-nine case reports, three case series, and eleven trials were included. Thirty-six cases of CGE were described, 12 surgical and 24 endoscopic. Perforation and death following CGE occurred in 81% and 14% of patients, respectively. The most common bowel preparations taken before CGE were enemas (42%) and oral preparations (31%), while 28% of patients did not undergo any bowel preparation. Bowel preparation was reported as inadequate in most CGE (solid stool in 65% and poor in 11%). The most frequent devices that triggered CGE were argon plasma coagulation during endoscopy (58%) and the electric scalpel during surgical procedures (75%). Published trials showed that adequate bowel preparation, together with endoscopic insufflation and suction, reduces intestinal levels of hydrogen and methane. CGE predominantly occurs in patients undergoing interventional procedures with inadequate bowel preparation. Achieving optimal bowel preparation, together with endoscopic aspiration, washing, and CO2 insufflation practically abolishes potentially explosive gas concentrations.

Systematizing risk assessment and responses to combustible dust from explosive characteristics

A systematic approach to defining dust explosion risks is presented, utilizing key parameters: minimum ignition energy (MIE), minimum ignition temperature of dust clouds (MITC), minimum explosion concentration (MEC), maximum explosion overpressure (Pmax), and the dust explosion characteristic index (Kst). These parameters form the basis for robustly assessing combustible dust explosion risks. Drawing on experimental findings, a safety evaluation method empowering plant operators to directly assess the safety of dust-handling processes was devised, ensuring effective dust explosion prevention. Evaluation of three common dust samples (aluminium, polyethene, and lycopodium) revealed varying explosion risks. Through comparative analysis with existing literature, this study aligns risk definitions, proposing a scoring method for process safety controls to effectively mitigate dust cloud explosion risks.

Influence of stearate dry coating on ibuprofen powder: What about the combustibility?

Dust explosion is one common type of process safety incident within the pharmaceutical industry. During powder processing, surface modification is widely used to increase dust flowability by alleviating inter-particle cohesion. However, it is currently unclear whether the addition of guest particles affects the combustibility of pharmaceutical powders. To investigate the explosion hazard of stearate-coated ibuprofen powder, this paper studied the ignition sensitivity and explosion severity of pure and coated ibuprofen by determining a series of explosion parameters in accordance with ASTM standards. The results indicated that the addition of stearate significantly reduced the minimum ignition energy of the mixture. Other parameters including the minimum ignition temperature, the minimum explosible concentration, the maximum explosion pressure, and the maximum rate of pressure rise were found to have less correlation with the improvement in dust flowability. Powder characterization through methods such as the Hausner ratio, scanning electron microscope, thermo-gravimetric analysis, and X-ray diffraction were employed to investigate chemical phase changes between coated mixtures and pure pharmaceuticals. The effects of improved dust flowability and dust dispersibility on the combustibility of ibuprofen dust were discussed to improve explosion-proof awareness in the pharmaceutical industry.

A modified phosphorus-based inhibitor for dry water inhibitor and its chemical mechanisms in preventing benzoyl peroxide explosion

Dust explosions caused by benzoyl peroxide (BPO) pose a significant risk to the chemical industry, making the development of high-performance inhibitors essential. The effect of a novel inhibitor on the explosion behavior of BPO dust was studied through experiments and simulations. The chemical mechanism behind the suppressed BPO dust explosion was clarified. The primary explosion hazard of BPO stems from the instability of the oxygen–oxygen bond. To address this, a novel phosphorus-based dry water powder inhibitor, MAP-DW, was prepared which effectively captures key reactive radicals involved in the chain reaction. At the optimal explosion concentration of BPO, a concentration of 400 g/m3 of MAP-DW reduced the maximum explosion pressure and the maximum explosion pressure rise rate by 96.48 % and 99.58 %, respectively. The suppression effects of MAP-DW on the explosion of BPO dust include heat absorption, oxygen dilution, thermal insulation, and capture of key free radicals. The kinetic simulation results showed that the suppression cycle between phosphorus-containing substances captured key chain reaction radicals, and the coupled suppression among NH3, H2O, and phosphorus-containing substances dominated the suppression mechanism of MAP-DW on BPO dust explosion. This study provides new insights into the characterization and suppression of BPO dust explosion, while also supplying crucial data for the safe utilization of peroxides.

Explosion characteristics of two-phase ejecta from large-capacity lithium iron phosphate batteries

When a thermal runaway accident occurs in a lithium-ion battery energy storage station, the battery emits a large amount of flammable electrolyte vapor and thermal runaway gas, which may cause serious combustion and explosion accidents when they are ignited in a confined space. With the gradual development of large-scale energy storage batteries, the composition and explosive characteristics of thermal runaway products in large-scale lithium iron phosphate batteries for energy storage remain unclear. In this paper, the content and components of the two-phase eruption substances of 340Ah lithium iron phosphate battery were determined through experiments, and the explosion parameters of the two-phase battery eruptions were studied by using the improved and optimized 20L spherical explosion parameter test system, which reveals the explosion law and hazards of the two-phase battery eruptions. Studies have shown that in a two-phase system explosion, EMC can make the two-phase system more explosive and more powerful, and the thermal runaway gas expands its explosion concentration range. The coupling explosion of the two enhanced the sensitivity and explosive power of the two-phase ejecta. Increasing the concentration of any combustible in a two-phase system will cause the explosion intensity parameters of the system to increase. However, when the combustible concentration exceeds the optimal explosion concentration, the explosion intensity parameters will decrease or even no explosion will occur. Both explosion intensity parameters and sensitivity parameters are more sensitive to EMC concentration, and the higher the EMC concentration, the stronger its dominant role in the explosion of the two-phase system. This work can lay the foundation for revealing the disaster-causing mechanism of explosion accidents in lithium-ion battery energy storage power stations, guide the safe design of energy storage systems and the prevention and control of explosion accidents, and provide theoretical and data support for the investigation of explosion accidents in energy storage power stations.

Explosion dynamics for thermal runaway gases of 314 Ah LiFePO4 lithium-ion batteries triggered by overheating and overcharging

Thermal runaway (TR) of LiFePO4 lithium-ion batteries (LFPs) can produce significant amounts of smoke, posing serious explosion hazards. This paper systematically investigated TR gas generation, explosion limits, explosion overpressure, and post-explosion gas compositions of 314 Ah LFPs under overcharging and overheating. Quantum chemical and explosion reaction kinetics calculations clarified the elementary reactions and compositional alterations occurring in gases and free radicals during the explosion process. The findings revealed that H2 constituted the primary component of TR gases, comprising 47.64 % and 53.12 % of the overcharging and overheating, respectively, followed by CO2 and CO. The ranges of explosion concentration for TR gases, when subjected to overheating and overcharging conditions, were 6.32–29.3 % and 6.83–26.91 %, respectively. At the point of maximum explosion overpressure (Pmax), the gas concentrations peaked at 15.86 % and 16.25 %. The elementary reaction R1 held a pivotal position in enhancing the explosion overpressure. As the TR gas concentration escalated, the Rate of Production (ROP) of R31 and R35 also surged, ultimately resulting in elevated concentrations of CO. The reactions R123, R250, and R279 facilitated the generation of H2 while simultaneously consuming hydrocarbon gases. This resulted in a risk of secondary explosion of the TR gas after the explosion. Post-explosion gas residual quantities followed the order: C2H6 < C2H4 < CH4 < H2 < CO. The results revealed crucial insights for developing explosion prevention and suppression in the process safety industry and Energy Storage Systems.

Identification of the Gas Explosion Hazardous Area in a Gob by Numerical Simulations-A Case study of the 6310 Working Face of Tangkou Coal Mine.

In the process of coal mining, gas explosion accidents occur frequently, which seriously affect the safety of mine production. Identifying the gas explosion hazardous zone in a gob is of specific guiding significance for the prevention and control of gas explosion in a coal mine. In this work, we analyze the porosity and gas concentration distribution in the gob after the working face was mined by combining the particle flow and finite-element simulation. A trianglular gas explosion hazardous zone is obtained by multielement coupling, and the CO2 injection simulation is then performed to eliminate the hazardous zone. The results show that the upper part of the gob and the edge of the return airway in the lower part are highly porous, and the porosities of other areas are relatively low with a value of 0.4. The gas concentrations in the upper left part and lower right part of the gob are relatively low, and the oxygen concentration distribution is the opposite. The gas explosion hazardous zone is mainly distributed near the oxidation zone. Yet, the simulation results reveal that after an injection of 97.5 m3/h of CO2, there is no area in the goaf that meets the gas explosion concentration conditions, that is, the oxygen concentration is greater than 12% and the methane concentration is greater than 5% but less than 16%, which can effectively eliminate the gas explosion hazardous zone.

Safety of Hydrogen Storage Technologies

While hydrogen is regularly discussed as a possible option for storing regenerative energies, its low minimum ignition energy and broad range of explosive concentrations pose safety challenges regarding hydrogen storage, and there are also challenges related to hydrogen production and transport and at the point of use. A risk assessment of the whole hydrogen energy system is necessary to develop hydrogen utilization further. Here, we concentrate on the most important hydrogen storage technologies, especially high-pressure storage, liquid hydrogen in cryogenic tanks, methanol storage, and salt cavern storage. This review aims to study the most recent research results related to these storage techniques by describing typical sensors and explosion protection measures, thus allowing for a risk assessment of hydrogen storage through these technologies.

Uniform Nanocrystal Spatial Distribution-Enhanced SnO2-based Sensor for High-Sensitivity Hydrogen Detection.

Hydrogen (H2) is colorless, odorless, and has a wide explosive concentration range (4-75 vol %), making rapid and accurate detection of hydrogen leaks essential. This paper demonstrates a method to modify the spatial distribution of nanocrystals (NCs) by adding surfactants to improve the sensing performance. In order to explore its potential for H2 gas-sensing applications, SnO2, containing different mass percentages of PdCu NCs, was dispersed. The results show that the 0.1 wt % PdCu-SnO2 sensor based on surfactant dispersion performs well, with a response to 0.1 vol % H2 that is 18 times higher than that of the undispersed 0.1 wt % PdCu-SnO2 sensor. The enhanced gas-sensing ability after dispersion can be attributed to the fact that the uniform distribution of NCs generates higher quantum efficiency and exposes more active sites on the carrier surface compared to nonuniform distribution. This study provides a simple, novel, and effective method to improve the sensor response.

Flame propagation, explosion hazard, and pollutant emission characterization of typical clean fuels leaks in plateau low-pressure region

To accelerate energy transformation and sustainable development, various countries are rushing to lay hydrogen doped natural gas pipelines. However, the installation of pipelines will pass through plateau low-pressure region, and the impact of low-pressure environments on the flame propagation, explosion hazards, and pollutant emission characteristics of hydrogen doped natural gas is not yet clear. To solve this problem, a combination of constant volume combustion experiment and numerical simulations is used. The characterization parameters of flame, explosion and pollutant concentration of natural gas/H2/air under low-pressure environment are obtained, and their chemical reaction kinetics are analyzed. When the pressure drops, the laminar burning velocity (LBV) of them increases, and the Lewis number (Le) gradually increases by more than 1. Thermal diffusion is stronger than mass diffusion, and the growth rate of flame thickness exceeds 26 %. The effect of hydrodynamic instability enhances, causing an increment in the average size of flame cells, the critical instability radius, and the Markstein length (Lu). At the equivalent ratio (φ) of 1, there is a change from negative to positive in the Lu, and flame stability continuously strengthens. The explosion overpressure is reduced by 78 % to 90 %, the explosion temperature by 16 % to 20 %. As the φ increases, the LBV exhibits an inverted U-shaped relationship, reaching its maximum value near “φ = 1″. The flame stability first weakens and then strengthens. The explosion hazard is strongest in the range of ”φ = 1–1.2″. With a decrease in pressure, the total reaction rate of fuel consumption is reduced by more than 50 %. The continuous reaction distance is extended by 12 %. Changes in pressure have a relatively weak impact on the content of CO and CO2. The increase in the φ results in an increase in CO content of over 7 %. The content of CO2 reaches its maximum value around “φ = 1″. It is an essential reference for the safe delivery of hydrogen energy and the reduction of environmental pollution.

Construction of ultra-sensitive hydrogen sensor based on two phases In2O3 nanoparticles modified by regular dodecahedral ZnO

Hydrogen (H2) is considered one of the promising energy sources to replace fossil fuels so efficient H2 sensing technology is a necessary condition to ensure the safety of people’s livelihood and economic development. In this paper, ZnO obtained by calcination of precursor ZIF-8 has a regular dodecahedral structure. The product of In2O3 obtained with the participation of the surfactant PEO-PPO-PEO has two different crystal forms, namely cubic phase c-In2O3 and hexagonal h-In2O3. Crystal form c-In2O3 is 7.07 wt% of the mass of h-In2O3. When ZnO is 5 wt% of In2O3, the H2 sensor based on the ZnO (5 %)-Inc/Inh composite material has the best response performance and the operating temperature is 450 °C. The sensor’s response time for detecting 5000 ppm H2 is less than 1 s, and the recovery time is 6 s with a response intensity of 79.91. The limit of detection (LOD) is 53 ppb, which is much lower than the explosive concentration (4–75 V/V%). Density functional theory (DFT) is utilized for investigating the performance advantages of Inc/Inh composites over pure c-In2O3 and h-In2O3 and further elaborating the mechanism of ZnO improving the gas-sensing performance of ZnO (5 %)-Inc/Inh. The sensor based on ZnO (5 %)-Inc/Inh composite may guide the research of high-performance H2 sensors. The H2 adsorption mechanism of the sensor was analyzed based on the oxygen adsorption mechanism.

Study on the variation regularities of minimum explosion concentration of moist magnesium dust/derived hydrogen hybrids under multiple working conditions

Magnesium is widely used but often accompanied by frequent magnesium powder explosion accidents. If the variation regularity and mechanism of the minimum explosion concentration (cm) of magnesium powder under the multi-factor coupling effect can be understood, the occurrence of magnesium powder explosion accidents can be fundamentally avoided, and intrinsic safety can be achieved. In this paper, experiments were conducted using a self-made 20 L explosion device to explore the effects of particle size, initial temperature, and equilibrium relative humidity (ERH) coupling on the cm of magnesium powder. The study found that an increase in ERH of moist magnesium powder would lead to easier agglomeration of the dust, making it less prone to activation. Additionally, excessive moisture also absorbed more heat, reducing the ignition sensitivity of the dust cloud and resulting in a continuous increase in cm. However, increasing the initial temperature and decreasing the dust particle size both decreased the cm of moist magnesium powder, weakening the effect of ERH on cm. Furthermore, using the analysis methods of orthogonal experimental range and AHP model, it was determined that the influence weights of the factors coupling effects on the cm of magnesium powder, from highest to lowest weight, were: particle size > ERH > initial temperature.Furthermore, in order to deeper understand the mechanism of the action process that affect the cm of moist magnesium powder, additional experiments were conducted to further confirm that the addition of hydrogen derived from the erosion reaction of moist magnesium powder to the explosion system can reduce the cm of magnesium dust clouds. Moreover, a quantitative mathematical model for predicting the cm of magnesium powder/hydrogen two-phase system was also established.

Study on flame propagation characteristic and mechanism of polypropylene dust explosion

Polypropylene dust explosion poses a significant threat to the safe production of synthetic resin. To elucidate the flame propagation mechanism of polypropylene dust explosions, the flame propagation characteristics of polypropylene dust were experimentally studied. The minimum explosible concentration (MEC) for polypropylene particles with diameter < 75 μm, 75–100 μm, and 100–212 μm was 50 g/m3,100 g/m3,150 g/m3, respectively. Obvious fluctuations were observed in the flame propagation velocity of small particles, with smaller particles exhibiting more pronounced fluctuations, primarily caused by thermal feedback between the particles in the preheating zone and the reaction zone. While for large particles, the flame temperature exhibited multiple peaks, resulted from the discrete flame floating in front of the flame. The combustion process of polypropylene dust comprised the diffusion combustion of large particles and the gas-phase combustion of combustible gases pyrolyzed by small particles.

Microfluidic preparation of surfactant-free ultrafine DAAF with tunable particle size for insensitive initiator explosives

High purity and ultrafine DAAF (u-DAAF) is an emerging insensitive charge in initiators. Although there are many ways to obtain u-DAAF, developing a preparation method with stable operation, accurate control, good quality consistency, equipment miniaturization, and minimum manpower is an inevitable requirement to adapt to the current social technology development trend. Here reported is the microfluidic preparation of u-DAAF with tunable particle size by a passive swirling microreactor. Under the guidance of recrystallization growth kinetics and mixing behavior of fluids in the swirling microreactor, the key parameters (liquid flow rate, explosive concentration and crystallization temperature) were screened and optimized through screening experiments. Under the condition that no surfactant is added and only experimental parameters are controlled, the particle size of recrystallized DAAF can be adjusted from 98 nm to 785 nm, and the corresponding specific surface area is 8.45 m2·g−1 to 1.33 m2·g−1. In addition, the preparation method has good batch stability, high yield (90.8%–92.6%) and high purity (99.0%–99.4%), indicating a high practical application potential. Electric explosion derived flyer initiation tests demonstrate that the u-DAAF shows an initiation sensitivity much lower than that of the raw DAAF, and comparable to that of the refined DAAF by conventional spraying crystallization method. This study provides an efficient method to fabricate u-DAAF with narrow particle size distribution and high reproducibility as well as a theoretical reference for fabrication of other ultrafine explosives.

Use of a two-parameter Weibull distribution for the description of the particle size effect on dust minimum explosible concentration

Combustible dust explosion properties, like Minimum Explosible Concentration (MEC) and Minimum Ignition Energy (or Temperature), have a strong dependency on the particle surface area to mass ratio which varies with the particle size distribution. Unfortunately, the comparison of the dust explosion properties reported in the literature for a given dust material is often difficult because of the lack of description of the particle size distribution which is usually limited only to scattered information about the median (d50), mean, or one, two, or maximum three percentiles (e.g., d10,d50,andd90). This approach often gives conflicted conclusions or observations of no trend with measured independent parameters. It seems that a different approach is necessary to comprehensively describe the dependency of dust explosion properties on the particle size distribution. Such improvement could be achieved using a continuous probability distribution of which an example is a two-parameter normal distribution. However, the normal probability density function can only represent a symmetrical bell-shaped distribution which does not apply to the dust particle size analysis that often results in a skewed bell-shaped histogram. This study explored the use of a two-parameter (shape and scale) Weibull probability density function to describe a particle size distribution. A series of experimental data on the Minimum Explosible Concentration (MEC) of sulfur and polyethylene dust samples for which the particle distribution is measured were used to estimate the Weibull's scale and shape parameters. Two- and three-dimensional plots were generated to demonstrate the correlations of these parameters with MEC. The results show that as the scale and shape parameters increase, the MEC increases with higher dependence on the scale parameter (b). This is consistent with the initial conclusion where the MEC increases with increasing particle size. The paper discusses the advantages of using such an approach to describe the effect of particle size distribution on dust explosion properties but also shows that using only a median or mean of a particle size distribution to describe MEC may be misleading, especially if a sample represented by d50 as a coarse distribution contains a long tail of fine particles.

Assessment of the danger of the release of deep hydrogen sulfide from the Black Sea to the surface

The relevance of this study is due to the fact that the Black Sea is the largest body of water with a hydrogen sulfide zone. The proven reserves of hydrogen sulfide in the water column of the Black Sea amount to five billion tons. In terms of volume, this corresponds to 3.5 trillion cubic meters. At the same time, a mixture of hydrogen sulfide with air is explosive starting with a concentration of hydrogen sulfide in the air of 50 g/ m3. In addition, hydrogen sulfide is toxic, since it is a nerve gas, deadly already at 1 g/ m3. It is of interest to assess the possibility of the release of hydrogen sulfide waters of the sea to the surface with their subsequent degassing, as well as the consequences of increasing the concentration of hydrogen sulfide in surface waters and in the air for coastal areas. The distribution of hydrogen sulfide in the Black Sea is well studied. Especially a lot of measurement data was obtained for the top layer at a depth of 1000 m. Data on the concentration of hydrogen sulfide at depths from 1000 m to 2000 m is significantly less for technical reasons. The maximum concentration of hydrogen sulfide in the sea is reached at depths above 1500 m. A numerical assessment of the consequences of the release of deep waters to the surface has been obtained. It is shown that the concentration of hydrogen sulfide in the air will not exceed 1 g/m3, which is almost two orders of magnitude less than the explosive concentration. The balance estimates of oxygen and hydrogen sulfide fluxes in the Black Sea are considered in connection with forecasts of a rise in the boundary of the hydrogen sulfide zone. It is shown that the rise of the boundary is a consequence of the imbalance of these flows, however, the amount of net hydrogen sulfide production cannot be estimated accurately enough. With an accuracy of estimates of the fluxes themselves of 20-30%, the resulting increase in the amount of hydrogen sulfide per year is a statistically insignificant amount. The release of hydrogen sulfide to the surface in the foreseeable future is possible if the stratification of waters is disrupted by mechanical intervention.

High-performance palladium nanotube network as fast, high-resolution, and wide range hydrogen detector in atmosphere

Due to its high energy density, cleanliness, and renewable properties, hydrogen (H2) has found wide applications in aerospace, fuel cells, biomedicine, and chemical production. However, ensuring its safety is crucial, and a quick response time for H2 leakage detection is urgently needed for subsequent explosion-proof measures, requiring a limit of less than 5 s. So far, there is no reported device with both high-resolution and wide range capabilities. In this study, we propose a novel solution by designing and fabricating a hollow palladium nanotube network (HPNN) as a rapid leaking-sensing H2 detector. The HPNN sensor demonstrates excellent performance with a low detection limit of 10 parts per million (ppm) and a fast response time of less than 0.6 s in atmospheric environment. These impressive safety characteristics are attributed to the unique structure of the Pd nanotube network, where both the lattice volume expansion effect and electron accumulation under mechanical deformation affect the electrical resistance. The device is capable of effectively detecting a wide range from 4 % to 0.001 % of H2 concentrations. Compared to previous results, the response speed is improved by over 8 times at the minimum explosion concentration (4 %) and two orders of magnitude at low limit concentration. Such simple and cost-effective manufacturing method offers potential for the development of high-performance hydrogen leakage detectors.

Grid‐based assessment of hydrogen leakages for an offshore process to improve the design and human performance

AbstractHydrogen is gaining global recognition as a sustainable energy source, but its combustible nature raises concerns, especially in congested offshore settings. Steam methane reforming (SMR) remains the predominant hydrogen production method; however, offshore SMR facilities exposed to harsh weather could potentially compromise safety because of leakages. This study uses the fire dynamics simulator (FDS) to carry out the first‐of‐its‐kind CFD modeling of hydrogen leakage and its wind‐influenced dispersion on an offshore SMR platform. It also provides the spatial risk that accounts for the probabilities of human errors and wind speeds. The study uses a grid‐based approach with 120 monitor points (MPs) to measure locally dispersed gas concentration. At 2 m/s wind speed, only nine grids contain explosive concentrations while the rest remain safe. At 5 m/s, the flammable zones increase by 133%, affecting 21 grids. Extreme wind speeds of 12.5 m/s have limited impact, but SMR1 exhibits higher stoichiometric concentrations. MPs 43–48 record flammable concentrations at all wind speeds; however, at 12.5 m/s the explosion risk is well below the threshold of 1 × 10−4 due to the low wind occurrence probability. Overall, this research contributes to addressing the safety concerns associated with hydrogen in offshore settings and provides a foundation for future risk assessments.

Gas Leakage Detection with Notification Alert and Auto Cut-off Valve

Good safety procedures must be put in place in places of employment and education since safety is important in today's environment. The safety model now in use in businesses and industries is modified by this work and can also be applied in residences and commercial buildings. Installing a gas detector in susceptible areas is single path to take preventative action against the risk of gas leaks. A gas detector, which is frequently a component of a safety system, is a gadget designed to identify the existence of gases within a given space. A gas detector that has the ability to alert nearby operators should be alerted to a potential leak so they can either address or evacuate the area. Numerous gases have the potential to be dangerous to organic life, including humans and animals, which makes this kind of equipment crucial. It is necessary to prevent containment into any region where gas shouldn't be present. Leaks are highly dangerous since even a tiny leak has the potential to gradually accumulate an explosive concentration of gas. Testing with a gas detector is the sole means by which users can identify gas leaks, today's gas detectors are less effective in their use. It is risky since gas leaks need to be detected as soon as possible. Because of this, the gas detector with notifies device was created to avoid explosions or fires from happening in buildings. As long as there is a power source, this type of gas detector will continuously detect gas. The Arduino UNO microcontroller was utilized in this project to interpret sensor input and transmit an SMS alert to a GSM module, allowing for user communication. Until the gas concentration reaches a harmful level, the buzzer will continue to ring. These projects have the advantage of preventing fires before they start, which can occur from cooking unsupervised without human monitoring or gas leak explosions.
