SAFETY PROFILE：

HYDROGEN sulfide is a highly toxic and flammable gas. Being heavier than air, it tends to accumulate at the bottom of poorly ventilated spaces. Although very pungent at first, it quickly deadens the sense of smell, so potential victims may be unaware of its presence until it is too late. For safe handling procedures, a HYDROGEN sulfide material safety data sheet (MSDS) should be consulted.
