What is one of the key roles of CHEMTREC?

One of the key roles of CHEMTREC is to offer emergency chemical information. This service is crucial for responding to chemical emergencies and providing immediate support to professionals dealing with hazardous materials. CHEMTREC acts as a vital resource, delivering accurate information about chemical substances, including potential hazards and safety protocols that should be followed in emergency situations. This capability is essential for ensuring the safety of workers, first responders, and the public when chemical incidents occur.

The other options do not accurately represent CHEMTREC's responsibilities. While training for applicators and monitoring pesticide sales are important aspects of pest management, they fall under other organizations or regulatory bodies. Similarly, the registration of pesticides is typically managed by entities like the Environmental Protection Agency (EPA) rather than CHEMTREC. By understanding that CHEMTREC's primary function is to provide emergency information, it becomes clear why this option is the best answer.
