1. SAFETY PRECAUTIONS
Personal Protective Equipment (PPE): Always wear safety goggles, hearing protection, and heavy-duty gloves when using the rotary hammer. Use respiratory protection when drilling in materials that generate dust.
Electrical Safety: Check power cord and extension cord for damage before use. Do not operate in wet conditions or near water. Use RCD where required.
Kickback Hazard: Maintain a firm grip and proper stance. Be prepared for sudden reactions if the bit jams. The overload clutch helps protect against extreme torque reactions.
Dust Hazard: Drilling in concrete and masonry generates silica dust. Use appropriate respiratory protection (at least P2 or N95 mask) and dust extraction where possible.
Maintenance: Unplug tool before changing bits or performing maintenance. Allow the tool to cool before storing.
Training requirement: Operators should be familiar with correct usage, bit selection, and safety procedures. Supervisors should ensure all safety protocols are followed.
2. FIRST AID MEASURES
Eye Injury (debris): Do not rub. Rinse immediately with plenty of clean water for at least 15 minutes, holding eyelids open. Seek medical attention.
Cut Injury: Apply direct pressure to stop bleeding. Clean wound with clean water. Cover with sterile dressing. Seek medical attention if bleeding is profuse or the wound is deep.
Skin Contact (dust): Wash skin with soap and water. If irritation develops, seek medical attention.
Inhalation of Dust: Move a person to fresh air. If symptoms persist (coughing, difficulty breathing), seek medical attention.
3. FIRE FIGHTING MEASURES
Flammability: The tool is not flammable, but plastic casing may burn if exposed to fire. Dust accumulation at the workplace can ignite.
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; water may be used for general fires but not for electrical fires where live equipment is involved.
