Where must the supplier's Safety Data Sheets (SDS) be kept?

• A. At the job site
• B. In the main office
• C. In the warehouse only
• D. On the vendor's website

Answer: (A)

Safety Data Sheets contain essential safety information for the chemicals being used, and workers need access to them where they are working. Having the SDS at the job site means anyone handling or exposed to the chemical can immediately review hazards, required personal protective equipment, first-aid steps, and spill procedures. This readiness is key for safe day-to-day operations and for responding quickly in an emergency. Keeping SDS only in the main office or warehouse or relying solely on a vendor website could delay access when you’re out on the site, which isn’t acceptable for effective hazard communication or compliance.
