4. Hazard Any source or situation with a potential for harm in terms of a human injury or

5. Risk It is the chance or probability that a person will be harmed or experience an
adverse health effect if exposed to a hazard. May also apply to situations with
property or equipment loss.

15. Hazard Level: Consideration should be whether the risks can be lowered, where applicable, to
Medium a tolerable level and preferably to an acceptable level, but the cost of additional
risk reduction measures should be taken into account
16. Hazard Level: Substantial efforts should be made to reduce the risk. Risk reduction measures
High should be implemented urgently within a defined period of time and it might be
necessary to consider suspending or restricting the activity, or to apply interim risk
control measures, until this has been completed. Arrangements should be made
to ensure that controls are maintained, particularly if the risk levels are associated
with extremely harmful consequences
17. Hazard Level: These risks are considered unacceptable. Substantial improvements in risk control
Very High measures are necessary so that the risk is reduced to a tolerable and acceptable
level. The work activity should be halted until risk controls are implemented that
reduces the risk so that it is no longer very high. If it is not possible to reduce the
risk, the work should remain prohibited.
