To begin with, you should know that window cleaning jobs do not have to be dangerous. If you do everything in the correct fashion, you will be as safe while you are cleaning the windows as you would be inside of the building itself. You do not need to be nervous about getting hurt. However, you do need to know that there are certain dangers that come along with this profession. If you know this, you can work to keep yourself safe at all times. It is better to understand these things and to respect them than to ignore them and assume that you will be safe. One danger is that your equipment itself can malfunction. Depending on the job, you may use a scaffolding that is attached to the roof or you may use one that lifts you up from the ground. It is important to go over these before every job to make sure that everything is in working order. A little bit of maintenance can ensure that there will not be any problems. You need to look for any signs of wear. This could include stress fractures or simply nuts and bolts that have come loose over time. Another danger is that you could fall if you do not strap yourself in. You will have a harness of some sort that will connect you to the lift. You need to make sure that you always have the lines connected and all of the snaps and buckles in place. You may get overconfident and eventually think that you do not need these safety mechanisms. If you catch yourself thinking this, make sure that you do not give in to the desire to free yourself from the restraints. These things are there to keep you safe, whether you have been doing the job for three days or twenty years. These are the two main dangers of window cleaning jobs. As you can see, both of them can be reduced to almost nothing with a little bit of work on your end. If you take the time to make sure that you are safe, this will not be a dangerous job for you to do.
