Question

A user spills a small amount of toner from a laser printer onto the floor. Which of the following is the safest way to clean up the toner?

Options

AUse a wet/dry vacuum.
BUse a broom and a dust pan
CUse damp paper towels.
DSpray the toner with canned air.

Explanation

Laser printer toner is an extremely fine powder that poses a respiratory and fire hazard if dispersed into the air. A wet/dry vacuum (ideally fitted with a HEPA or toner-rated filter) safely contains the particles without scattering them. Using a broom and dustpan (B) would launch fine particles into the air, creating an inhalation risk. Damp paper towels (C) can cause toner to smear and bond to surfaces, making cleanup harder and potentially damaging flooring. Spraying with canned air (D) is the worst option-it would blast toner particles throughout the room, creating a serious inhalation hazard.
