Employees should be alert to what type of conditions and know their proper response?

The correct response emphasizes the importance of being aware of hazardous conditions in the workplace. Hazardous conditions can encompass a wide range of potential dangers, including physical hazards like machinery, slippery floors, and chemical spills, as well as environmental factors such as poor air quality or exposure to extreme temperatures.

Awareness of these hazards is crucial for maintaining a safe work environment. Employees must not only recognize these conditions but also know the proper protocols for responding to them, such as reporting them to a supervisor, using personal protective equipment (PPE), or following emergency procedures.

The other options do not relate directly to the proactive safety measures needed in the workplace. Visual conditions or favorable conditions do not inherently represent danger and thus do not require the same level of vigilance or response. Compliant conditions refer to being in accordance with safety regulations, but understanding and responding to hazardous conditions is fundamental to ensuring workplace safety.
