22.214.171.124.3 Windows. Provide non-porous framed windows, double glaze, where
appropriate, with a thermal barrier feature. Equip windows with interior
security mesh if the facility is not enclosed (surrounded) by a climb-
resistance chain link (security) fence and security gates. As an alternative,
do not provide windows.
Interior Partitions and Ceilings. For clean areas, partitions
shall be masonry or gypsum board on metal studs extending to the underside of
a gypsum board ceiling and all joints shall be sealed. Drop ceilings shall
not be used in pesticide areas.
Roofing. For general roofing criteria, refer to MIL-HDBK-1001/5,
Roofing and Waterproofing. Only include roofing systems as contractor's
options that will be compatible with the pesticides that may be discharged
from the exhaust hood onto the roof.
Structural. Construct facility in accordance with MIL-HDBK-1002/1,
Structural Engineering - General Requirements.
Interior Design. Coat floors, interior partitions and interior
surface of exterior walls, and ceilings with nonabsorbent finish in the
pesticide areas only. In the clean areas, collateral equipment should include
a desk, bookcase, file cabinet, telephone (essential), a small table with one
chair per worker (recommended), and benches (essential). Install metal
shelving to store pesticides (essential).
Operational Note. Pest management facilities shall not be used for
hazardous waste storage unless specifically designed to accommodate
hazardous waste materials since other federal regulations apply to
hazardous waste facilities. The facility supervisor must be aware of
this distinction and establish the practice of sending all hazardous
wastes to an established hazardous waste facility without delay.
General. Isolate pest management facilities from congested areas
and security. This is based on the similarity of requirements for the
isolation of storage facilities for pesticides, flammable or explosive
materials (hazards), and sewage treatment plants (vapors and odors). Pest
management facilities contain toxic pesticides and in special circumstances,
usually emergencies, may be required to provide interim storage for pesticides
classified as hazardous wastes in accordance with 40 CFR 165.10 and 40 CFR
261. The most compelling reason for isolation of pest management facilities
is fire safety. If a fire occurs in a facility within a building complex,
extensive decontamination of nearby areas from drift of toxic vapors, smoke,
liquids, and particulates is required. This condition is confined to one
structure when the facility is isolated. Isolated single purpose structures
