supplied air mode or according to specific OSHA standards or applicable government regulations, whichever
is lower.

containing less than 19.5% oxygen.
2. Do not use when concentrations of contaminants are immediately dangerous to life or health, are
unknown or when concentrations exceed 10 times the permissible exposure limit (PEL) when used in air-
purifying mode, or according to specific OSHA standards or applicable government regulations,
whichever is lower. When used as a straight, Type C, continuous flow supplied air respirator, the
