Under Federal OSHA 29 CFR 1910.1200, local establishments are required to keep a Material Safety Data Sheet on file when:

• A. Hazardous materials are used or stored on site
• B. All chemicals present on site are never stored
• C. The facility operates 24 hours a day
• D. No hazardous materials are on site

Answer: (B)

Under OSHA’s Hazard Communication Standard, you must have a current SDS for any hazardous chemical that is present in the workplace. That means an SDS is required whenever hazardous materials are used or stored on site so employees have access to hazard information, safe handling procedures, PPE, and emergency measures. If there are no hazardous chemicals on site, there’s nothing to file. The requirement isn’t about how many hours the facility operates or whether chemicals are stored; it’s about the presence of hazardous materials.
