Carry out a fire-risk assessment identifying any possible dangers and risks.
Consider who may be especially at risk.
Get rid of or reduce the risk from fire as far as is reasonably possible and provide general fire precautions to deal with any possible risk left.
Take other measures to make sure there is protection if flammable or explosive materials are used or stored.
Create a plan to deal with any emergency and, in most cases, keep a record of your findings.
Review your findings when necessary.
