Since we went quite severely off Jaspers original topic, could we continue any discussion on hazard & risk in here?
Kurnal has pointed out, from both the BS and the BS EN on Fire Vocabulary:
3.343
fire hazard
potential for injury and/or damage from fire
3.374
fire risk
product of the probability of occurrence of a fire to be expected in a given technical operation or state, and
the consequence or extent of damage to be expected on the occurrence of a fire (simply put: likelihood x severity)
Looking just at fire risk, as I have said before, just cutting the probability down will very rarely mean that you can reduce any form of protection, so since you are going to protect against it anyway, is lowering the probability just an exercise in futility? (It clearly won't be to insurance companies though) To me it is simple to defend in court, as you would have to prove that people were put at risk of death or serious injury, so providing people can and do get out safely, surely I have fulfilled my duty?
Probabilities do have a place in things, particularly in cause and effect / fault trees, when we are looking at a chain of events/failures causing a problem. But with these we should generally start from the point of actually having a fire, (i.e. The actual probability of having a fire is irrelevant yet again) as we are generally interested in the workings and the outcome from that point onwards. There is also the probability of fire spread, from a point of origin, but again we copnsider the fire as a starting point so its likelihood is irrelevant.
Saying there is no point protecting against the probability is a bit extreme, but I think it raises a question as to whether the RRFSO is truly linked to prevention in the way people think it is, are we preventing the fire or preventing person from harm if there is a fire?
Re: Article 4.
If you read the guidance note it says quite clearly that the article is intended to show the clear difference between precautions due to process risks, and general fire precautions. Article 4 is one of the only times that likelihood is mentioned in the order apart from in reference to explosive atmospheres. In the guidance note the word is linked with consequences, but any need for reduction is always pointing towards reducing the risk.
From the CLG guides;
The aims of the fire risk assessment are:
• To identify the fire hazards.
• To reduce the risk of those hazards causing harm to as low as reasonably
practicable.
• To decide what physical fire precautions and management arrangements are
necessary to ensure the safety of people in your premises if a fire does start.
Everything seems to be worded to avoid directly saying that anyone is expected to lower the actual likelihood of fire.
