To get a clear understanding of the risk assessment process you need to understand what is meant by the terms ‘Hazard’ and ‘Risk’ in the lexicon of health and safety. These are terms that are often used interchangeably but actually have very distinct meanings.
What is a Hazard?
Hazards are anything that can cause harm, damage or adverse health effects to people in the workplace.
A flammable substance is an example of a HAZARD. If the flammable substance is near an open flame, then obviously the RISK of an unplanned fire is higher. If it is stored safely the risk is much lower.
No fuel station can avoid the ‘hazard’ of flammable substances. However, effective measures are in place to ensure that fires at fuel stations are very rare. These measures lower the ‘risk’.
Some activities bring multiple ‘hazards’. When working on a ladder, staff could fall and be injured. So, falling is a hazard. They could also drop an object from height and harm a co-worker. This is also a hazard.
When hazards are understood, steps can be taken to reduce the associated risks. For example, tool tethering will reduce the risk of a dropped object. Appropriate ladder safety training will reduce the risk of falling.
What is a risk?
Risk, in health and safety, is the likelihood or chance of a person being injured or receiving an adverse health effect due to a specific hazard.
It’s useful to keep these definitions clear and separate in your mind when considering risk assessments. They are often confused which makes risk assessments harder to consider.
For example, you might have heard offices referred to as low-risk workplaces. Technically, offices are low-hazard workplaces because staff are not exposed to many hazards, such as climbing ladders or handling chemicals.
However, a particular office may have a faulty fire alarm. This means that, if there is a fire, there is a high risk that staff will not evacuate quickly enough because they won’t hear the alarm. So, in this example, the office may be low-hazard, but it is not low risk.
