Our surveyors use Trimble UTS, Universal Total Stations. These machines do not broadcast a laser beam unless a measurement is being taken. Other lasers may constantly broadcast a laser beam on a jobsite, which can expose workers to more energy. Leica Rugby lasers are used by grade setters and have an energy output of 2.5 milliwatts.
While our lasers are low hazard, OSHA still has some requirements to make everyone around the lasers safe. The following requirements are followed by those using or exposed to lasers:
- Training of laser operators - cards verifying this training are issued to laser operators.
- Training of all other workers to ensure they do not intentionally stare at laser beams or direct laser beams at another person.
- Laser should not be used in explosive environments.
- PPE - safety glasses, which are required by Delta, are sufficient. Special laser glasses are not required unless energy exceeds 5 milliwatts.
- Signage – placards are to be posted in the area of the laser to warn others.
- Do not look at lasers using binoculars.
- Lasers are to be turned off when not in use.
- Shutters or caps can be used when laser transmission is not needed.
- Label on laser must be visible and legible and show maximum output.
- Whenever possible, ensure unit is set up above the heads of workers.
- Rain, snow, dust or fog can increase the laser beam visibility and laser use should be minimized in these conditions.
- Set up the work area to minimize the chance of traffic coming into the area. Use cones to mark the work area and wear class 2 vests.
- Do not open or modify housing of laser.
- Do not use damaged or defective lasers.
Make sure that you observe the safety requirements and work safely around the lasers. Also observe laser operators and avoid entering their work area. While operating the laser, their focus is not on traffic in their area.
