Which practice helps ensure safety in working spaces above service equipment?

Providing sufficient lighting in working spaces above service equipment is crucial for ensuring safety. Adequate lighting allows workers to see clearly, reducing the risk of accidents and injuries that can occur due to poor visibility. When workers can see what they are doing, they are more likely to avoid hazards such as live wires, mechanical components, and other potential dangers present in these areas. Proper lighting also aids in identifying and resolving issues quickly, which is essential for maintaining a safe and efficient work environment.

While minimizing obstructions, using non-conductive materials, and installing warning signs also contribute to safety, they do not directly address the visibility aspect that sufficient lighting provides. Each of these measures plays a role in creating a safer workspace, but clear visibility remains a fundamental requirement, making adequate lighting a critical practice in ensuring safety in these environments.
