Where must Safety Data Sheets (SDS) be kept on a painting job site?

• A. In the main office only.
• B. On-site, in a known location, easily and quickly accessible to exposed workers.
• C. In the vehicle.
• D. In the supplier's facility.

Answer: (B)

SDS need to be readily accessible at the worksite to anyone who could be exposed to hazardous substances. On a painting job, workers may handle paints, solvents, and cleaners, so having the SDS in a known, clearly marked place on-site means they can quickly check hazard information, safe handling, PPE requirements, and emergency steps when needed. This immediate access helps prevent accidents and supports proper response if a spill, exposure, or adverse reaction occurs.

Keeping SDS in the main office may delay access for anyone working away from that area, while storing them in a vehicle or at the supplier’s facility doesn’t provide timely information when you’re actively using materials on site. So the best approach is to keep them on-site in a location that exposed workers can reach quickly.
