To obtain hazard and response information, a firefighter can contact the manufacturer using:

• A. The Packaging Label
• B. The MSDS
• C. The Phone Number on the MSDS
• D. The Product Logo

Answer: (C)

When you need reliable hazard and response information, you go to the source closest to the chemical—the manufacturer. The Safety Data Sheet (MSDS) is the document that compiles the chemical’s specific hazards, handling and firefighting guidance, and it also provides the emergency contact information for the manufacturer. Using the phone number listed on the MSDS gives you direct access to experts who can provide tailored, up-to-date instructions for that chemical, including what extinguishing media to use, containment steps, and actions for exposure or spills.

Packaging labels can indicate basic hazards, but they don’t offer the detailed response guidance or a direct, 24/7 emergency line. The product logo has no safety or procedural information.
