AG Mechanics CDE Practice Exam

Which of the following types of fire extinguishers should be available for use in the welding area?

1. Class A, B and C

2. Class B and C

3. Class D only

4. Class K only

The correct answer is: Class A, B and C

In a welding area, multiple types of fire hazards can be present, including combustible materials (Class A), flammable liquids (Class B), and electrical equipment (Class C). Therefore, to ensure comprehensive coverage and the ability to address various fire scenarios, it is essential to have fire extinguishers that can tackle all these types of fires. Choice A, which includes Class A, B, and C fire extinguishers, is the correct option as it covers all three potential fire hazards in a welding area. Options B, C, and D do not provide a complete range of fire extinguishers needed for a welding area. Option B only covers flammable liquids and electrical fires, neglecting combustible materials. Option C is specific to Class D fires, which involve combustible metals, not commonly found in welding areas. Option D is for Class K fires, primarily kitchen fires involving cooking oils and fats, not relevant to welding areas.
