HAZOP's and HAZAN's

HAZOP's and HAZAN's are now well established tools in the reduction of Risks.

HAZOP is a formal technique engaging the operator and designer and any other experts on the process to review possible hazards and operating problems that may arise. A HAZOP study brings together the combined experiences of the study team stimulating each other and building upon each others ideas in a systematic way

HAZAN, similar to the risk reduction analyses it consists of three steps:

Estimate how often the incident will occur

Estimate the consequence to

	Employees
	The public and and the environment
	Plant and profit

Compare the results of the above frequency and consequence with a target or criterion normally based on the principles of ‘As Low As Reasonably Possible’ (ALARP)
