a. Removal.
Remove all jewelry such as rings, dog tags, bracelets, etc. If jewelry or tools contact positive
electrical circuits, a direct short may result. Damage to equipment and injury or death to personnel
may occur.
Ensure air pressure is drained to 0 psi (0 kPa) before taking off any air components. If pressure is
not released, components could blow off and harm personnel. The IHMEE air system is pressurized
to 119 psi (820 kPa). Do not drain air from a tank with any part of body in air spray path. Skin
embolisms and/or debris in eyes can occur from released pressure. Failure to comply may result in
injury or death to personnel.
