Laser Levelling & Measurement

This Standard Operating Procedure (SOP) outlines essential safety practices and hazard management for using laser leveling and measurement tools. It is designed for workers and supervisors in civil works who operate laser equipment, ensuring compliance with relevant safety legislation. The document covers risks like laser exposure, equipment stability, and environmental safety, promoting safe working conditions and reducing the risk of accidents.

• Direct or specular reflection of laser beam into the eye → retinal burn or permanent blindness (Class 3R and higher)
• Even Class 2 visible lasers may cause flash-blindness or after-images if viewed directly
• Tripod tip-over or instrument fall from height → struck-by or instrument damage
• Trip hazards from tripod legs, cables, and survey targets
• Battery (lithium-ion) fire or thermal runaway in cordless laser instruments
• Misreading or misuse of laser distance meter at heights leading to incorrect setting-out
• Beam exiting the work area into adjoining workplaces, public roads, or aircraft flight paths
• Working in traffic during external surveying
