In the event of a substantial chlorine leak, which agency should be contacted for assistance?

• A. Local emergency services
• B. The Chemical Transportation Emergency Center
• C. The Environmental Protection Agency
• D. The Occupational Safety and Health Administration

Answer: (B)

The Chemical Transportation Emergency Center (CHEMTREC) is the appropriate agency to contact in the event of a substantial chlorine leak. CHEMTREC specializes in providing immediate emergency response assistance for hazardous materials incidents. They have access to a wealth of information about chemicals, including chlorine, and can guide responders on how to handle spills, leaks, and other dangerous situations involving hazardous substances.

In contrast, while local emergency services can respond to on-the-ground emergencies, they may not have the specialized knowledge regarding chemical behavior and hazard management that CHEMTREC offers. The Environmental Protection Agency (EPA) focuses on environmental regulations and pollution control, which may be relevant in the long term but not for immediate emergency response. The Occupational Safety and Health Administration (OSHA) primarily ensures workplace safety and health, which is important for workers’ protection but not directly involved in emergency chemical incidents. Therefore, contacting CHEMTREC in the event of a chlorine leak is the best course of action for immediate and specialized assistance.
