FAQs

1. What Are Workplace Hazards?

Workplace hazards are any sources, situations, or conditions that can cause harm, injury, illness, or damage in a work environment. These hazards can be physical, chemical, biological, ergonomic, psychosocial, or related to workplace safety procedures.

Key Points:

• Can lead to accidents, injuries, or long-term health issues.
• Must be identified and controlled through workplace safety measures.
