Fire has a devastating effect on businesses with many never recovering after a major fire.
Building and stock can be insured against but not being able to trade is where the biggest losses lay.
If you are unable to fulfill contracts, chances are your customer will go elsewhere, and then there is always the risk that they will not return once you start trading again.
The best precaution against fire is prevention.
Having staff trained in fire awareness and fire safety will go a long towards prevention. These will teach your staff how to spot potential hazards and how to act and contain a fire if one did break out.
