What is an example of an engineering control in the context of crime scene cleanup?

An example of an engineering control in the context of crime scene cleanup is locking out all electrical sources. This practice involves physically disabling equipment or machinery to prevent accidental access to electrical power during cleanup operations. By isolating electrical sources, you minimize the risk of injury from electrical accidents, which is a crucial aspect of ensuring safety in environments where hazardous materials or potentially dangerous situations exist, such as crime scenes. Engineering controls focus on removing hazards or creating physical barriers to protect workers, making this method particularly effective in promoting safety and preventing accidents in crime scene cleanup scenarios.

The other options relate to additional safety measures but do not fall under the category of engineering controls. Personal protective equipment consists of gear that individuals wear to protect themselves, while implementing safety programs pertains to organizational policies aimed at enhancing overall safety. Scheduling work shifts, while relevant for managing worker fatigue and well-being, does not modify or control the physical environment in which the work takes place. All these approaches are important but encompass different aspects of safety management.
