Explosion Proofing. Pesticide concentrates ordinarily used in
structural pest control work have flash points above 140 degrees Fahrenheit
(60 degrees Celsius), Reference 40 CFR 1900.106. They may be combustible
(flash point above 100 degrees Fahrenheit or 38 degrees Celsius) but are not
flammable (flash point below 100 degrees Fahrenheit or 38 degrees Celsius). A
hazardous area classification is not applicable if flammable pesticides (flash
point below 100 degrees Fahrenheit or 38 degrees Celsius) are not stored or
Operational Note: Service pest management consultants should recommend
pesticides with flash points above 140 degree Fahrenheit (60 degrees
Celsius) to avoid the need for explosion proof features. The excessive
cost of explosion proof motors and switches can be avoided by storing or
using pesticides with flash points greater than 100 degrees Fahrenheit
(38 degree Celsius). If flammable pesticides are required for use in
the installation pest management program, as determined by the service
pest management consultant, the pesticides must be stored in a separate
flammable liquid storage cabinet outside of the facility. Additional
details on these lockers is given in paragraph 3.7.1.
