Q

One disadvantage of using regular dry chemical (sodium bicarbonate) in firefighting is that __________.

🔍 Key Concepts

• Regular (sodium bicarbonate) dry chemical vs. other dry chemicals (like multipurpose/ABC) • How storage stability and chemical breakdown under heat affect extinguishing agents • What makes an agent safe or unsafe around oil fires and electrical equipment

💭 Think About

• Ask yourself: What is sodium bicarbonate basically the same as in everyday life, and how stable is that substance when stored in a sealed container for long periods? • Think about what each wrong choice is claiming: Does sodium bicarbonate suddenly become dangerous or ineffective in situations where it is actually commonly used (oil fires, electrical fires, or heat)? • Consider which option describes a problem that would most realistically concern maintenance crews who must keep extinguishers in service for years.

✅ Before You Answer

• Check which type(s) of fire sodium bicarbonate dry chemical is specifically rated for (look at standard fire extinguisher class ratings). • Verify whether regular (BC) dry chemical is considered safe for use on electrical and flammable liquid (oil) fires in standard firefighting guidance. • Think about whether long-term storage is usually a big concern for dry chemical agents compared with liquids or foams.
