Laser Safety

Depending on what trade you work and what task you’re working on, lasers can help get the most accurate measurement in half the time. No more dirty caulk covered plum bob, grab a laser, turn it on and presto, you’re good to go. These types of lasers have made our lives so much easier, from measuring to cutting, but they do come with a serious hazard, that no one really talks about. So let’s dive in.

All lasers are an “amplified” light source. This light is so amplified that it can cause permanent vision loss and third degree burns. There are different classes of lasers and you need to know exactly which class you’re working with. Some classes will need extra training. The lowest power lasers are class 1 and 2. These lasers will not harm in normal working conditions. They are not strong enough to burn your skin and your blink reflex will occur before any damage is done to your eye. However, taking a bet on how long you can stare into the laser would definitely not be advised. You will cause damage. The medium powered lasers are class 3R and these ones can cause some serious injuries if focused directly into the eye. Don’t forget that reflections of the laser bouncing into your eye or a co-worker’s eye can still cause damage. The most high powered laser you may come across on site is class 3B and 4. To use these lasers, you will need extra training and a trained laser safety officer to guide the way…..and for good reason! These high powered lasers can cause all sorts of injuries. From permanent vision loss, third-degree burns all the way to actually severing a limb! Yes, you heard that right, some class 4 lasers can cut parts of you clean off.

Always know what class of laser you are working with, the hazards associated with it and have the proper training. Use your JHA’s to identify all the hazards. Post warning signage to alert other workers not to enter when higher powered lasers are in use and of course wear the proper PPE. Lasers can be so helpful, so follow the proper protocol to keep them helpful and not a hazard.
