technical manual shall observe the following instructions. Disregard of these warnings may result in

serious or fatal injury to personnel. The altitude sensor parachute staging unit (ASPSU) contains a class

C explosive in the cutter mechanism of the cutter module. Procedure steps shall be followed to prevent

early activation and possible personal injury. When the security pin is pulled the explosive will discharge

Tetrachloroethylene will only be used in areas where substantial ventilation is available. Repeated or

prolonged inhalation of the solvent vapors can be detrimental to human health. In addition, avoid

prolonged or repeated contact of the solvent fluid with areas of the skin. Tetrachloroethylene must not

be taken internally.

Insure that pressure chamber on ASPSU test set is depressurized before attempting to open chamber
