(4) Notes about PROTECTIVE CLOTHING SETS.
If firefighters are equipped with normal heat-resistant bunker suits and SCBA, they do
not need Protective Clothing Sets 2 and 3.
Symbol 2, Figure 10 (page 13) requires that firefighters wear a gas mask or SCBA to
combat fires in areas so marked. This usually involves incendiary and other readily
flammable chemical agents.
Symbol 3, Figure 10 (page 13) means just what it says: "No Water". Use of water on the
chemicals so marked could spread the fire or cause an explosion. This usually involves
chemicals such as oil based incendiaries, metallic sodium, TEA or aluminum zinc oxide
hexachloroethane (HC) smoke.

maintain. Be particularly aware of their compatibility grouping and color coding.
