ALARP stands for “As Low As Reasonably Practicable.” It is a principle that is used in risk assessment and risk management to determine the appropriate level of risk control. It means that, when assessing risks, the risk should be reduced to a level that is as low as reasonably practicable, taking into account the cost, benefits, and likelihood of the risk.

The ALARP principle is based on the idea that some level of risk is acceptable, as long as it is kept as low as reasonably possible. This means that measures should be taken to reduce risks as much as possible, but there is a point at which the cost of further risk reduction becomes disproportionate to the potential benefits.

The ALARP principle is often used in industries that have the potential to cause harm, such as the chemical, construction, and transportation industries. It helps ensure that risks are controlled to an acceptable level while also taking into account the practical and economic considerations of risk management.
