Use

Butanethiol decomposes an heading and release toxic fumes. It reacts with strong acids, bases and strong oxidants. Workers during handling of butanethiol should be very careful, should avoid open flames, sparkings, and smoking. Chemical vapor/air mixtures cause explosion ha3 and workers should wear protective cloathing, safety goggles and breathing apparatus and should work in good ventillation
