What should be done to ensure that emergency showers function properly?

Regular maintenance checks are essential to ensure that emergency showers function properly because they help identify and rectify any issues such as blockages, leaks, or mechanical failures that could prevent the shower from working effectively in an emergency. These checks should include testing the flow of water, inspecting the plumbing system, and ensuring that the water temperature is suitable. Regular assessments not only guarantee that the equipment complies with safety standards but also confirm that it will perform as intended when needed most, protecting individuals from hazardous spills or exposure.

Other measures mentioned might enhance the visibility or accessibility of emergency showers, but they do not directly address the operational integrity of the showers themselves. For example, while installing them at specific heights might cater to ergonomics, it does not ensure that the water flow and spray functionality are working correctly. Painting them bright colors can improve visibility but does not contribute to their mechanical readiness. Limiting access to trained personnel could hinder immediate response in an emergency situation, further emphasizing the importance of functional reliability ensured through regular maintenance checks.
