An ad hoc committe PLATO
Executive Order 12196 was issued on 26 February. It applies to all agencies of the Executive Branch of the US Government, except military personnel and uniquely military equipment. In broad terms, it requires that each Executive Agency furnish to employees places and conditions of employment that are free from recognized hazards that are causing or are likely to cause death or serious physical harm, establish and operate a formal Occupational Safety and Health Program, designate an agency official to manage that program, and comply with the OSHA standards except where an alternative agency standard may be approved by the Secretary of Labor. This Executive had little effect on OSHA, other than expanding somewhat its advisory role to other Federal agencies. Its effect on the Army was to require that Army operation's that were not uniquely military in character had to comply with OSHA standards. However, enforcement was from within the Department of Defense.
