You are not clear from your post if you are looking soley at the training aspect of fire safety of whether it is the Management of fire safety in general. For example do you need to inlcude costs for servicing and repair of fire equipment such as extinguishers, alarms, emergency lighting. You may want to seperate the training budgets into Fire Warden training, and staff awareness training - the latter can be delivered in house however you may be required to factor this into the budget as lost time (as with down time for fire drills which, if you work on a large site can be quite a lengthy process).

I assume you already have a fire risk assessment for the site, this should identify everything that you need to do to ensure fire safety at your workplace - make sure that you add any remedial/control measures which require a budget into your budget proposal.

If you don't have a fire risk assessment you need to get one - is there a competent person in your workplace to complete one, or will this be an additional budget cost?
