Which of the following hazards might signs at a worksite warn about?

Signs at a worksite are typically used to communicate important safety information to employees, highlighting potential hazards that could pose risks to their health and safety. In this context, warnings about physical hazards from chemicals present are crucial. Such hazards can include toxic substances, flammable materials, or chemical reactions that may lead to injuries, health issues, or even fatalities if proper precautions are not taken.

Informing workers about these dangers allows them to take necessary measures, such as wearing protective equipment or following specific safety protocols, thereby reducing the likelihood of accidents and creating a safer work environment. This proactive approach to safety is fundamental to effective risk management in any workplace where chemical exposure is a possibility.
