Owning a house means you will eventually need to have repairs done. This could mean doing them yourself, or hiring someone to do them for you. In either case, you should be thinking about the dangers involved and how to keep yourself, your family, and those working for you safe.
Safety concerns could be the reason why the work needs to be done in the first place. It is important to take care of problems as soon as possible. It is always regrettable when someone gets hurt, but even more so when it could have been prevented.
You can perform a safety inspection yourself by considering where your family or guests are likely to walk and how they would interact with the area around your home. Does anything stand out as a possible danger to the unaware? If so, find out what you can do to remedy the situation.
Never attempt to do repairs that you are not comfortable with, especially not those that involve electricity or elevated areas, since your lack of experience will make it much more likely that you are hurt on the job.
