Which statement about cleaning inside the hazardous hoods is correct?

• A. Cleaning agents should be sprayed into the hood from top to bottom, front to back.
• B. Cleaning agents should be sprayed into the hood from bottom to top, front to back.
• C. Cleaning agents should be sprayed into the hood from bottom to top, back to front.
• D. Cleaning agents should be sprayed into the hood from top to bottom, back to front.

Answer: (A)

Cleaning inside hazardous hoods should be done from the top down and from the front toward the back. Starting at the top helps prevent dirty liquids from dripping onto surfaces you’ve already cleaned, and moving downward uses gravity to carry residues away as you wipe. Sweeping from the front toward the back directs any runoff toward the rear exhaust area, away from you at the hood opening, reducing the chance of exposure. Cleaning in the opposite directions would either push contaminants toward areas you’ve already cleaned or toward your work zone, increasing recontamination and exposure risk.
