GENERAL INFORMATION1-1. of MANUAL . This is the OPERATOR'S MANUAL for use with the M20A1 Simplified Collective ProtectionEquipment (SCPE). Name and Model Number. Simplified Collective Protection Equipment: of Equipment. The SCPE provides a clean-air shelter for use against chemical and biological warfareagents and radioactive particles. The SCPE is an inflatable shelter which allows personnel to perform duties withoutwearing individual protective Limitations.

7 The M20A1 SCPE should be deployed in a structurally sound building. It MUST NOT bedeployed outside, where it would be subject to wind, rain, solar heat loading, or direct contact with liquid agents. TheSCPE does not provide:(1)Environmental control equipment (heating and cooling); however, interfaces are provided.(2)A portable source of electrical power (electrical generator).(3)NBC detection devices.(4)Protection from nuclear radiation, however, the SCPE does provide protection against radioactiveparticles.(5)Protection from carbon monoxide exhaust MAINTENANCE FORMS AND of the Army forms and procedures used for equipment maintenance will be those prescribed by DAPAM 738-750, The Army Maintenance Management System (TAMMS).1-3.
