13 Hazard Types
- Mechanical hazards: Tools, equipment, machinery and any object may contain pinch points, sharp points and edges, weight, rotating parts, stability, ejected parts and materials that could cause injury.
Mechanical hazards include moving parts, nip and pinch points, and rotating shafts.
- Pressure: Increased pressure in hydraulic and pneumatic systems. Pressure may cause ruptures in pressure vessels, whipping hoses. Small high pressure leaks may cause serious injuries.
- Radiation: Electromagnetic radiation hazards vary depending on the frequency (wavelength) of the energy. Generally, the higher the frequency, the more severe the potential injury. Non-ionizing (ultra-violet, visible light) may cause burns. Ionizing radiation actually has the potential to destroy tissue by dislodging electrons from atoms making up body cells.
- Toxic substances: Materials that in small amounts may cause injury to skin and internal organs are considered toxic. Toxics may enter through inhalation, ingestion, absorbed or injected.
- Vibration/Noise: Produce adverse physiological and psychological effects. Whole-body vibration is a common hazard in the trucking industry. Segmental vibration and noise hazards exist when working with equipment, such as jack hammers.
