The Deltona job has this respirable-dust condition: dry cutting concrete produces visible dust. Which safety control should be used?
Correct Answer
C) dust-control method
Silica-producing tasks require dust controls and housekeeping methods that reduce exposure.
Why This Is the Correct Answer
Silica-producing tasks require dust controls and housekeeping methods that reduce exposure.
Why the Other Options Are Wrong
Option A: cut faster to beat the dust
cut faster to beat the dust may relate to another site control, but it does not remove or guard the silica exposure control exposure being tested.
Option B: open the doors for airflow
open the doors for airflow may relate to another site control, but it does not remove or guard the silica exposure control exposure being tested.
Option D: wet the floor afterward
wet the floor afterward may relate to another site control, but it does not remove or guard the silica exposure control exposure being tested.
Memory Technique
Name the harm before the guard; cut, faster, beat cannot stand in for Safety Coordinator.
Reference Hint
Open-book path: tab OSHA 29 CFR 1926 to Subpart Z, 1926.1153 Respirable crystalline silica; verify the OSHA safety threshold or jobsite control before answering.
