A lifestyle guide for shedworkers since 2006
As with any building you should know how you are going to get out if there is a problem. The risk in a shed are increased because the building itself may be flamable and you may also have flamable chemicals in it. You need to take care with choice of insulation materials and get an approved electrician for any electrical work.A small fire extinguisher by the door and a power shut off switch next to that would also be a good idea.
I almost forgot. Heaters are another big risk item, don't dry your socks on them and go off an forget them. Make sure you have good ventilation if you have a bottled gas heater or you will poison yourself with carbon monoxide.Something I spotted on the "fun police" on TV the other night. If you are working on your own then the safety laws are not as strict as when you are working with employees.
