WARNING

Filters and masks of the NBC system will not protect you against carbon monoxide, ammonia,

acid, or solvent fumes. Be sure the carrier is properly ventilated. Do not let any filters of the

agents out of the air. Contaminated filters must be handled using adequate precautions and

must be disposed of by trained personnel. If it is very cold outside, there is danger of frostbitten

lungs from inhaling the cold air. Do not connect the hoses to your M42 mask canister until NBC
