At an emergency incident, the firefighter may obtain appropriate MSDS information from:

• A. CDC
• B. EPA
• C. OSHA
• D. CHEMTREC

Answer: (D)

In an emergency, firefighters need immediate access to product-specific hazard information to decide on protective gear, decontamination, and containment actions. The best source for MSDS/SDS information on scene is CHEMTREC, which runs a 24/7 emergency information line connecting responders to the chemical manufacturers and distributors. They can provide the exact hazards, first-aid measures, PPE recommendations, firefighting guidance, and spill-control procedures for the chemical involved. The other agencies—CDC, EPA, OSHA—focus on public health guidance, environmental regulation, and workplace safety standards, but they do not serve as the on-scene source for MSDS data.
