Flammable dust clouds pose an explosive hazard.

• A. False
• B. True
• C. Not sure
• D. Sometimes

Answer: (B)

Flammable dust suspended in air can form an explosive cloud. When that cloud encounters an ignition source, the flame can spread rapidly through the dispersed fuel, causing a violent explosion, especially in enclosed or confined spaces. This is a well-established hazard in many industries where dust is produced or handled, such as baking, woodworking, or metalworking. So the statement is true because the right combination of dust, air, and ignition can lead to a dust explosion. Saying false would ignore a real safety risk, while “not sure” or “sometimes” understates how consistently dangerous dust clouds can be when the conditions align.
