Answer: (A)

When a chemical emergency happens, you need immediate, expert hazard information from a service that specializes in chemical incidents. CHEMTREC is a 24/7 hotline designed to provide technical guidance on chemical hazards, help identify the products involved, and connect responders with the right safety data and response steps. That specialized support is why this option is the best choice in an emergency—it gives you authoritative, real-time information to guide containment, exposure control, and communications with responders or medical professionals. The general emergency number is for life-threatening situations and local responders, not for chemical-specific technical guidance, and the other numbers shown aren’t CHEMTREC and should not be used for chemical hazard information.
