Which of the following is a key function of safety signage in the workplace?

Safety signage in the workplace is essential primarily for informing and guiding employees about potential hazards. This function is critical because it provides clear, visible information that helps workers understand risks present in their environment and the safety measures they should take. For instance, warning signs alert employees to electrical hazards, slippery surfaces, or required personal protective equipment, allowing them to take necessary precautions before encountering such hazards.

While signage may add visual elements to the work environment, this is not its primary purpose. The role of signs is not to replace verbal instructions, as they complement spoken safety protocols rather than substitute them. Additionally, while certain signs can indicate break times, this does not encompass the broader and more vital role of safety signage in mitigating hazards and enhancing overall workplace safety. Thus, the central function of safety signage lies in its capacity to inform and guide employees effectively.
