Once the hazards have been identifed and the consequences and likelihood understood then the risk can be assessed.

The hazard analysis will determine how bad the hazard is and how often it could occur.  This needs to be compared to tolerability criteria so that a judgement can be taken on the acceptability of the risk.

Tolerbility criteria can come in many forms - the best source is to use relevant 'good practice' where possible.  Complex process plants require more detailed assessment and semi-quantitative or even fully quantitative risk assesment is required.  For these we draw upon published numerical tolerability criteria -for example R2P2 (http://www.hse.gov.uk/risk/theory/r2p2.htm).

We will provide a proportionate risk assesment for your process using our experience and judgement to analyse only to the depth required.

LOPA is a popular and useful semi-quantitative risk assesment technique.  Please see our separate web page linked to it on the left.


Risk of what, to what,  from what and ultimately .................so what?
