1. SAFETY PRECAUTIONS
Personal Protective Equipment (PPE): Always wear safety goggles or face shield, hearing protection, heavy-duty gloves, and appropriate respiratory protection. For heavy-duty use, wear a full face shield and leather apron.
Kickback Hazard: Hold tool firmly with both hands. Do not stand directly behind the disc. Use the correct disc for the task. Maintain a secure stance. KickBack Control on select models provides additional protection.
Disc Safety: Inspect discs for damage before use. Use discs rated for grinder speed. Do not use damaged or cracked discs. Ensure the disc guard is correctly positioned between operator and disc.
Electrical Safety: Use Residual Current Device (RCD). Do not operate in wet conditions or near water. Check power cord and extension cord for damage before use.
Fire Hazard: Sparks can ignite flammable materials. Clear work area. Do not use near flammable substances. Have a fire extinguisher readily available.
Dust Hazard: Some materials generate hazardous dust (silica from masonry, lead from old paint, chromium from stainless steel). Use local exhaust ventilation and appropriate respiratory protection (at least P2 or N95 mask).
Maintenance: Unplug tool before changing accessories or performing maintenance. Allow the tool to cool before storing.
Training requirement: Operators must be trained on correct usage, disc 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, lukewarm 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.
Burn Injury (hot metal or disc): Immediately cool affected area with cool running water for at least 10 minutes. Cover with sterile dressing. Seek medical attention.
3. FIRE FIGHTING MEASURES
Flammability: Grinder is not flammable, but sparks generated during use can ignite flammable materials. Plastic casing may burn if exposed to fire.
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.
