When pickling acid is used on metal, phosphine gas forms quickly. Phosphine gas is colorless,
poisonous, a fire hazard, and can explode. Do not smoke or use pickling acid near open flame.
Provide adequate ventilation, and do not breath vapors. Pickling acid can cause serious burns.
Wear a rubber apron, gloves, and safety goggles or lenses. If splashed in eyes or on skin, flush
with cool clean water, and refer to First Aid for Soldiers Manual FM 21-11.
Avoid contact with live steam. Live steam can burn skin, cause blindness, and cause other
serious injury. Safety goggles or lenses must be worn when using live steam. Eye injury can
occur if eye protection is not worn..
