Laser Level and Rotating Laser Safety
Laser levels and rotating lasers are used extensively on construction sites for setting out levels, checking gradients, and aligning structures. While most construction lasers are Class 2 or Class 3R, they can still cause eye damage if the beam enters the eye directly. Rotating lasers sweep the beam across a wide area, potentially affecting many workers. Operators must be trained in safe use, and warning signs must be displayed wherever lasers are in operation on site.
Key Hazards
Eye damage from direct or reflected laser beam exposure to unprotected eyes
Incorrect level data from poorly calibrated or incorrectly set up laser equipment
Tripping over tripods and laser equipment positioned in walkways and work areas
Beam reflecting off glass or polished surfaces striking workers in unexpected directions
Control Measures
- Ensure all laser operators are trained in the safe setup, use, and limitations of the equipment.
- Display laser warning signs in the area where the laser is operating to alert all personnel.
- Never look directly into a laser beam or point the laser towards another person's face.
- Calibrate the laser equipment at the intervals specified by the manufacturer and maintain records.
- Position tripods and equipment away from walkways and traffic routes to prevent trip hazards.
- Switch off the laser when it is not actively being used rather than leaving it running unattended.
- Be aware of reflective surfaces such as glass, polished metal, and water that redirect the beam.
- Use the correct laser class for the task and do not use higher-powered lasers than necessary.
- Store laser equipment securely in its protective case when not in use to prevent damage.
Remember
- Construction lasers can cause eye damage if the beam enters the eye directly even briefly.
- Warning signs must be displayed wherever lasers are in use to alert workers in the area.
- Never look directly into any laser beam or point the laser towards another person.
- Reflective surfaces redirect laser beams unpredictably so be aware of glass and polished metal.
- Calibration must be maintained because an inaccurate laser produces incorrect level data.
- Switch off and store the laser when it is not actively in use rather than leaving it running.
