contaminants must be equipped with engineering controls that prevent operators from receiving
exposures that exceed the occupational exposure limits. Engineering control methods include,
but are not limited to, containment in cabinets or hoods, reduced temperature for vapor reduction,
wet methods for dust control, and local exhaust ventilation to remove contaminants from the air.
Controls must be designed to maintain toxic vapor/particulate concentrations below the
permissible exposure limits established by OSHA in Title 29 CFR, part 1910, and by ACGIH,
and to maintain flammable vapor concentrations at a maximum of 25 percent of the Lower
Explosive Limit (LEL). If properly designed and used, control devices will minimize personnel
exposure to hazardous substances and prevent the buildup of an explosive atmosphere. The
Industrial Hygiene Office should periodically monitor recoupment workrooms to assure that the
control devices are functioning properly.
(4) Special MHE, such as a hydrolift carrier, may be required for managing large
(5) Recoupment of highly toxic materials, infectious substances, and cytotoxic drugs should
be performed in a glove box or biological safety cabinet.
c. Safety and emergency equipment must protect personnel from exposure or injury and the
facility from damage in the event of a mishap involving hazardous materials. Safety and
emergency equipment requirements include the following:
(1) Appropriate personal protective equipment (PPE) generally consisting of gloves,
goggles, boots, and coveralls. Additional PPE such as respirators, face shields, and chemical-
resistant coveralls, may be required depending on the material's hazardous characteristics. When
selecting PPE, consideration must be given to the chemical and physical characteristics and
related hazards of the material and to the protection already given by facility and equipment
controls. A job safety analysis must be conducted to determine the exact PPE requirements
based on the tasks being performed and the materials used. The safety and health officer and/or
industrial hygienist should be consulted concerning additional PPE requirements.
(2) Eyewash/shower stations that conform to the "American National Standard for
Emergency Eyewash and Shower Equipment" (ANSI Z358.1), or the individual military service
equivalent, must be provided. Eyewash/shower stations should be situated within 25 feet from
each recoupment workstation. Competent authorities should assure that tempered water (i.e.,
60oF. to 95oF.) is provided to eyewash/shower stations and that valves are designed to provide a
continuous flow of water for at least 15 minutes without the need for constant activation. A
shutoff valve should be provided to enable deactivation of the system when required.
(3) First-aid kits and fire blankets should be strategically located within the facility unless
individual military service policy specifies otherwise.
(4) Spill control and containment equipment including absorbents, neutralizers, and
chemical mops should be available.
(5) Fire extinguishers containing the appropriate fire extinguishing media should be
provided in each recoupment workroom and interim storage area.
