(8) Make sure that chemicals which may react together to produce dangerous fumes, fires, or explosion are
stored a safe distance from one another.
(9) Make sure that volatile liquids and flammable products are kept away from heat sources, open flames,
direct sunlight and electrical switches.
(10) Make certain that there is no open flame or exposed heating element nearby when pouring highly volatile
(11) If combustible chemicals or volatile liquids are spilled, clean up the area of the spill immediately.
(12) Always pour acid into water, never pour water into acid.
(13) Waste must be stored in vapor-proof safety containers, and must be disposed of following instructions from
the facilities/environmental engineers in the local SOP's.
(14) Never throw a glowing match into a refuse container.
(15) Keep oily rags in a metal, airtight, closed container. Do not store oily rags in cabinets or drawers.
(16) Keep heat and open flames away from gas cylinders. Do not bounce or drop gas cylinders.
(17) Check electrical wiring for defective insulation, sparking from loose connections, and overloaded circuits.
(18) Make certain laboratory and storerooms are adequately ventilated.
(19) Check fire fighting equipment periodically to make certain it is the proper type and ready for use. This is
done by checking seals, tags, pressure gages and hoses. Refer to Appendix A for manual reference for use of hand
portable fire extinguishers for Army users.
c. Extinguishing Fires. Laboratory personnel must be familiar with the nature of petroleum fires, with procedures for
fighting fires, and with fire-extinguishing equipment.
(1) Dry Chemical Extinguisher. The dry chemical extinguisher contains a dry chemical powder and a carbon
dioxide cartridge that forces the powder out of the extinguisher. Heat of the fire causes partial decomposition of the dry
powder; the powder cools and smothers the fire. The stream of dry chemical is played at the base of the fire and then
moved slowly over the fire. As dry chemical is a nonconductor of electricity, it may be used on electrical fires.
