🔍 Key Concepts

• Differences between Class A, B, and C fires (what is burning in each type) • What dry chemical actually does to the fire (how it stops the reaction) • How to read the label/markings on portable extinguishers on board

💭 Think About

• First, recall which fire classes involve ordinary combustibles, which involve flammable liquids, and which involve electrical equipment • Think about whether dry chemical conducts electricity or not, and how that affects which class of fire it can safely be used on • Consider whether all dry chemical extinguishers are identical, or whether their suitability for different classes depends on how they are rated and marked

✅ Before You Answer

• Verify what types of materials are involved in Class A, Class B, and Class C fires • Check how the extinguisher label indicates the classes it is approved for (letters, symbols, or both) • Confirm whether the exam expects you to assume the extinguisher is used according to its marking/rating, not generically on any fire
