Operational Safety: Ensure the tool is placed on a stable surface or securely mounted. Self-levelling range is ±4°; if exceeding this range, tool will not self-level .
Maintenance: Clean laser windows regularly with a soft cloth. Do not use aggressive cleaning agents. Have repairs performed only by authorised service centres.
Training requirement: Operators should be familiar with basic laser functions and safety precautions. Supervisors should ensure all safety protocols are followed, particularly regarding laser safety.
2. FIRST AID MEASURES
Eye Exposure (laser beam): If laser beam enters the eye, close eyes and turn head away immediately. If irritation persists, seek medical attention.
Skin Contact: Generally not harmful. If irritation develops, wash with soap and water.
Battery Leakage: Avoid skin contact with battery acid. Wash affected area with soap and water. Seek medical attention if irritation occurs. If acid enters eyes, rinse with plenty of clean water for at least 15 minutes and seek immediate medical attention.
3. FIRE FIGHTING MEASURES
Flammability: Device housing is not highly flammable but may burn if exposed to fire. Batteries may leak or rupture if exposed to high temperatures.
Extinguishing Media: Use water spray, foam, dry chemical powder, or carbon dioxide (CO₂) for fires involving tools.
Fire Response: In event of fire, evacuate the area and call emergency services. Use appropriate extinguishers. Do not inhale fumes from burning batteries or plastics.
