Who is responsible for abating asbestos hazards according to contamination sources?

The correct choice emphasizes that all employers who contribute to or have control over asbestos contamination are responsible for addressing those hazards. This highlights the principle of accountability in occupational safety and health regulations, which often place the onus on the parties that generate or manage hazardous conditions.

In the context of asbestos management, this means that any employer whose activities lead to asbestos exposure, whether through renovation, demolition, or maintenance, must take steps to mitigate those risks. This responsibility is crucial in ensuring a safe work environment and is aligned with regulatory standards, such as those established by the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA).

In contrast, other options limit responsibility to specific groups or deny accountability altogether. Singular assignments of responsibility, like only the general contractors or only the inspector, undermine the collaborative effort necessary to manage asbestos hazards effectively. No responsibility implies a lack of compliance with safety regulations and a failure to protect workers and the environment. Therefore, the broader approach that recognizes the accountability of all relevant employers aligns with established safety practices and regulations regarding asbestos management.
