Identifying Safety and Health Hazards
Hazards, risks, outcomes

The terminology used in OSH varies between countries, but generally speaking:

A hazard is something that can cause harm if not controlled.
The outcome is the harm that results from an uncontrolled hazard.
A risk is a combination of the probability that a particular outcome will occur and the severity of the harm involved.

“Hazard”, “risk”, and “outcome” are used in other fields to describe e.g. environmental damage, or damage to equipment. However, in the context of OSH,
***“harm” ***generally describes the direct or indirect degradation, temporary or permanent, of the physical, mental, or social well-being of workers.
For example, repetitively carrying out manual handling of heavy objects is a hazard. The outcome could be a musculoskeletal disorder (MSD) or an acute back or joint injury. The risk can be expressed numerically (e.g. a 0.5 or 50/50 chance of the outcome occurring during a year), in relative terms (e.g. "high/medium/low"), or with a multi-dimensional classification scheme (e.g. situation-specific risks). - Wiki
