1.2. Carbon monoxide.
Carbon monoxide is a colorless and odorless gas. Inhaling it can cause death or serious long-term health problems like brain damage. Symptoms include headaches, dizziness, nausea, and breathlessness.
DO NOT use Petrol/Diesel-powered equipment inside homes, garages, tents, camper vans, caravans, or boats. If in doubt, contact your dealer.
If you suspect carbon monoxide poisoning:
- Get to fresh air immediately. Turn off the machine if safe to do so.
- Call emergency services. Do not enter a suspected area.
- Contact a doctor immediately and inform them of suspected carbon monoxide poisoning.
DO NOT use in an enclosed area or a moving vehicle.
1.3. General fuel safety.
CAUTION: ALL FUELS ARE FLAMMABLE
- Keep fuel away from all sources of ignition (heaters, lamps, sparks).
- DO NOT carry out hot work on fuel tanks.
- Keep the work area clean and tidy.
- Clean up spills promptly using absorbent materials and dispose of waste correctly.
1.4. Fuelling/De-fuelling.
CAUTION: ALL FUELS ARE FLAMMABLE
- ALWAYS fuel and defuel in a well-ventilated area outside of buildings.
- Wear appropriate PPE, such as safety gloves and overalls.
- Avoid inhaling fumes when fuelling/de-fuelling.
- Use a proprietary fuel retriever for de-fuelling.
- Carry fuel in the correct and clearly marked container.
1.5. Electrical safety.
Electricity can kill. NEVER work on LIVE/ENERGISED equipment.
- Identify electrical isolation methods and isolate all electrical supplies before maintenance.
- Before use, check all electrical cables, plugs, and connections for damage (bare wires, chaffing, cuts, loose wiring).
- If damage is found, the item must be taken out of service until repaired by an electrically competent person.
- Route trailing cables to prevent trip hazards.
- NEVER work on or near electricity with wet hands, clothing, or gloves.
1.6. Batteries.
Corrosive
Batteries can leak electrolyte, which is an acid causing serious burns. Handle with care.
- If electrolyte contacts skin, remove contaminated clothing, wash with water, and seek medical assistance. Advise medical staff of the acid type (lead/acid = sulphuric acid; nickel/cadmium = potassium hydroxide).
- If electrolyte contacts eyes, wash immediately with large amounts of water and seek medical assistance.
- Gases from charging batteries are highly flammable; charge in well-ventilated areas.
- Avoid short-circuiting battery terminals, as this can cause an explosion. Use insulated tools.
1.7. Vibrations.
Prolonged exposure to vibrations can lead to conditions like white finger (Raynaud's phenomenon) or carpal tunnel syndrome.
- Wear gloves and keep hands warm.
- Take regular breaks.
- Observe the condition of your hands and fingers. Seek medical attention if symptoms occur.
1.8. Noise.
The operating noise can damage hearing. Wear hearing protection (earplugs or ear defenders).
- Be aware that hearing protection reduces your ability to hear alarm warnings.
- Limit noisy work to approved times and periods.
- Advise people working nearby to wear hearing protection.
Refer to the CERTIFICATE of CONFORMITY for Outdoor Noise declaration.
1.9. Additional safety instructions.
- Carry out inspection before starting each time.
- Keep the generator at least 1 meter from other objects and combustible materials to prevent fires.
