When choosing appropriate eyewear, time is also a consideration. The eyewear shall be used in a manner so that the damage threshold is not exceeded in the worst case exposure situation. Skin burns can result from contact with these gases. If these cryogenic gases leak into a closed room, they are capable of replacing the oxygen in the air, thus creating an oxygen-deficient atmosphere. Electrical shock or electrocution may occur from contact with exposed utility power.
Exposures can occur during setup, installation, maintenance and service of the laser.
The protective covers are often removed to allow access to the components. Fire is also potential hazard with Class 4 laser systems. The use of flame-retardant materials should be encouraged. Given the ease and results of this tool, it's easy to see why lasers are becoming more prevalent in the average veterinary practice. Even with the potential risks of using lasers, many practices use them with excellent safety records and clinical results.
