Hazard Types

All workplaces have hazards, which can be classified as:

• biological
• chemical
• radiation - a hazard posed by:
  • nuclear substances
  • X-ray devices, and lasers
• physical
• ergonomic
• psychological

While biological, chemical and radiation hazards are more commonly found in research environments, a workplace like an office might have ergonomic hazards (e.g., improper workstation set up), physical hazards (e.g., excessive cords) or psychological hazards (e.g., workplace bullying).
