Methyl mercaptan (CH4S)
Methyl mercaptan (CH4S) is a colourless flammable gas with an unpleasant odour described as rotten cabbage. It is highly ignited. When heated to decomposition, it emits highly toxic fumes and flammable vapours. Vapours from liquefied methyl mercaptan gas are heavier than air and may collect in low-lying areas. Olfactory fatigue may prevent adequate warning of hazardous concentrations.
Methyl mercaptan (CH4S) effects on health
Methyl mercaptan gas is irritating to the eyes, skin and respiratory tract. Edema of the airway and lungs can occur. Other possible effects include headache, dizziness, tremors, seizures, nausea, vomiting and lack of coordination. The gas is rapidly absorbed in the lungs. Skin and eye absorption are minimal; however, upon direct contact with eyes or skin, liquified methyl mercaptan will likely cause frostbite injury.
CAS-Number: 74-93-1.
How to detect CH4S
Due to the high toxicity and flammability of methyl mercaptan (CH4S), the use of reliable gas detection equipment is essential in environments where this gas is present. At WatchGas, we offer advanced gas detectors designed to provide real-time monitoring and early warning in case of hazardous methyl mercaptan leaks. The SST Serviceable is an ideal solution for continuous monitoring, offering high-precision sensors, visual and audible alarms, and a robust design suited for harsh environments.
Ensure workplace safety with our devices
Given the health risks and fire hazards associated with CH₄S, companies must implement strict safety protocols and use reliable gas monitoring equipment to mitigate risks. Proper ventilation and emergency response measures are critical in environments where CH4S is stored or used. By integrating our devices into safety procedures, businesses can protect personnel, prevent hazardous exposures and maintain regulatory compliance.
