What precaution is necessary when working with equipment that might contain PCBs?

1. Ensure electrical devices are non-conductive

2. Confirm proper disposal procedures are followed

3. Avoid contact with water at all times

4. Use only labeled containers for storage

The correct answer is: Confirm proper disposal procedures are followed

The necessity of confirming proper disposal procedures when working with equipment that might contain polychlorinated biphenyls (PCBs) is crucial due to the hazardous nature of these substances. PCBs are toxic chemicals that pose serious environmental and health risks if not managed correctly. Proper disposal procedures ensure that any equipment containing PCBs is disposed of in compliance with federal and state regulations, minimizing the risk of contamination and exposure. Additionally, managing PCB waste correctly involves specific steps, such as using licensed hazardous waste disposal services and following regulations by agencies like the Environmental Protection Agency (EPA). This precaution prevents environmental pollution and protects public health, given that improper disposal can lead to soil and water contamination, affecting ecosystems and human communities. Other options focus on different aspects of safety, but they do not directly address the specific hazards and regulations associated with PCBs. For instance, ensuring that electrical devices are non-conductive relates more to electrical safety rather than PCB management. Avoiding contact with water may be relevant in some contexts, but it does not directly mitigate the risks associated with handling PCBs. Using only labeled containers for storage is a good practice for hazardous materials generally; however, it lacks the direct impact of ensuring that the disposal of PCBs follows the established legal and
