Risk control, also known as
hazard control, is a part of the
risk management process in which methods for neutralising or reduction of identified risks are implemented. Controlled risks remain potential threats, but the probability of an associated incident or the consequences thereof have been significantly reduced.
Risk control logically follows after
hazard identification
A hazard analysis is used as the first step in a process used to assess risk. The result of a hazard analysis is the identification of different types of hazards. A hazard is a potential condition and exists or not (probability is 1 or 0). It may ...
and
risk assessment
Broadly speaking, a risk assessment is the combined effort of:
# identifying and analyzing potential (future) events that may negatively impact individuals, assets, and/or the environment (i.e. hazard analysis); and
# making judgments "on the to ...
.
The most effective method for controlling a risk is to eliminate the hazard, but this is not always reasonably practicable. There is a recognised
which is listed in a generally descending order of effectiveness and preference:
* Elimination - the complete removal or avoidance of the hazard also removes the risk.
* Substitution - A less hazardous or lower risk material, equipment or process may be available.
* Isolation - If the hazard can be separated from the people or equipment at risk by barriers or demarcated areas. the risk is reduced.
* Safeguards - Tools or equipment, can be modified by fitting guards, interlocks and similar engineering solutions.
* Procedural methods – Safer ways to do something.
* Personal protective equipment and clothing (PPE) is the last resort.
A combination of two or more of these methods may be most effective, or even necessary.
