When thinking about your risk assessment, remember:
• A HAZARD is anything that may cause harm, (such as chemicals, electricity, working from ladders, an open drawer etc)
• the RISK is the likelihood, that somebody could be harmed by these and other hazards, together with an indication of how serious the harm could be.

HAZARD and RISK A HAZARD is anything that may cause harm A live tiger is always a hazard A live tiger, except perhaps when it is anaesthetised, always has the potential to cause you harm and is therefore, always a hazard. Even the proverbial toothless tiger can harm you because, not only can it give you a nasty suck, it still has claws! In general ‘A HAZARD is anything that may cause harm’ and, because a tiger can harm, it is a hazard.
HAZARD and RISK RISK is the likelihood, that somebody could be harmed by these and other hazards A tiger which is free to roam about is a risk because it is likely that it will cause harm to someone.
In general, a risk is the combination of the severity of harm and the likelihood that the harm will occur.
Risk increases as the severity of the harm increases, or the likelihood of the harm increases, or both.
A loose tiger in the centre of a town is a higher risk than a loose tiger in the jungle because it is more likely to harm someone in a town.
A tiger in a cage is a low risk because it is unlikely to have the opportunity to inflict harm.
