Emergency centers such as CHEMTREC provide:

• A. Occupational Safety and Health Administration
• B. National Fire Protection Association
• C. National Center for Disease Control
• D. CHEMTREC®

Answer: (D)

Emergency centers like CHEMTREC exist to provide immediate access to chemical hazard information and expert incident guidance around the clock. They connect responders and facilities with trained specialists who can interpret safety data sheets, assess hazards, and steer actions to contain and mitigate a chemical incident. They’re not regulatory or public health organizations. OSHA is a workplace safety regulation agency, NFPA publishes safety codes, and CDC handles disease control. The service that specifically matches being an emergency information resource for chemical incidents is CHEMTREC.
