Which statement indicates a need for safety caution before cleaning a dryer vent?

• A. Disconnect power to the dryer and ensure it is completely cool; for gas dryers, shut off the gas supply if applicable.
• B. Leave power on while cleaning.
• C. Remove the vent cover while the dryer is running.
• D. Use water to flush lint.

Answer: (A)

The main idea is safety first: isolate the dryer from power (unplug it) and let it cool, and for gas dryers, shut off the gas supply. This reduces the risk of electric shock if you touch energized parts, prevents the drum or other moving components from turning unexpectedly while you’re handling lint and vent connections, and lowers the chance of burns from hot surfaces. Turning off the gas eliminates the possibility of a gas leak or ignition from any sparks or heat during cleaning. Why this is best: you’re working with lint, which is highly flammable, and with metal and electrical components that can cause harm if energized or hot. Ensuring the appliance is completely off and cooled provides a safe, stable environment to access and clean the vent. Why the other practices aren’t appropriate: keeping power on while cleaning can lead to shock or the dryer starting unexpectedly; removing the vent cover while the dryer is running can expose you to moving parts and hot air, and may spread lint or cause injury; using water to flush lint introduces moisture into electrical components and can create corrosion or electrical hazards.
