• Pull the pin: Remove the safety pin from the handle of the extinguisher to break the tamper seal and prepare the extinguisher for use.
• Aim the nozzle at the base of the fire: Direct the nozzle towards the source of the flames, as this is where the fuel is burning.
• Squeeze the handle: Apply pressure to the handle to release the dry chemical extinguishing agent.
• Sweep the nozzle from side to side: Move the nozzle back and forth to cover the entire area of the fire and ensure that all flames are extinguished.
• Continue until the fire is completely extinguished: Keep spraying the chemical agent until you are certain that the fire is out and there is no chance of re-ignition.
• Ensure the area is safe before leaving: Verify that the fire is fully extinguished, and stay vigilant in case the fire reignites due to residual heat or flammable materials.

Advantages:

1. Leaves no residue: CO2 extinguishers do not leave any chemical residue, making them ideal for use around sensitive electrical equipment.
2. Effective on electrical fires: Carbon dioxide effectively displaces oxygen around electrical fires, smothering the flames without damaging electronics.
3. Non-conductive: CO2 is a non-conductive gas, making it safe to use on live electrical systems without the risk of electrical shock.

Disadvantages:

1. Limited range: CO2 extinguishers have a short effective range, meaning they must be used close to the fire, which could expose the user to danger.
2. Can cause thermal shock to electronics: The extremely cold discharge of CO2 can damage sensitive electronic components by causing thermal shock.
3. Risk of asphyxiation in confined spaces: CO2 displaces oxygen, which can be dangerous if used in confined spaces where there is a risk of suffocation.

Common sources of danger:

1. Exposed live wires: Live wires can cause electrocution if touched accidentally.
2. Overloaded circuits: Overloading circuits can cause them to overheat, leading to electrical fires.
3. Faulty equipment: Defective or poorly maintained equipment increases the risk of electrical malfunctions.
4. Improper grounding: Poor grounding can lead to electrical shocks or damage to equipment during power surges.
5. Wet or damp environments: Water conducts electricity, and the presence of moisture can increase the risk of short circuits and electrocution.

Mitigation strategies:

1. Regular inspections and maintenance: Routine inspections help identify and fix potential hazards like exposed wires or damaged equipment before accidents occur.
2. Use of protective coverings and enclosures: Proper insulation and covers protect live wires and components from exposure to workers or the environment.
3. Implement overload protection devices: Circuit breakers and fuses can prevent circuits from overloading and reduce the risk of electrical fires.
4. Ensure proper grounding and bonding: All electrical systems should be properly grounded to prevent shocks and equipment damage.
5. Keep electrical equipment dry: Avoid placing electrical installations in areas prone to moisture, and ensure waterproofing measures are in place where necessary.

1. Select appropriate PPE for the task: Ensure that the right type of PPE is chosen based on the specific hazards of the task, such as gloves for chemical handling or helmets for falling object protection.
2. Inspect PPE before use: Always check PPE for any damage, wear, or defects before use. If PPE is damaged, it should be replaced immediately to ensure proper protection.
3. Follow manufacturer’s instructions: Adhere to the manufacturer’s guidelines for fitting, adjusting, and using the PPE correctly, ensuring that it provides maximum protection.
4. Wear PPE throughout the entire task: PPE should be worn continuously while exposed to hazards, and not removed until the task is complete and the environment is deemed safe.
5. Safely remove PPE to avoid contamination: When removing PPE, especially if it has been exposed to hazardous materials, follow proper techniques to avoid cross-contamination, such as removing gloves by peeling them off from the inside.
6. Clean and store PPE properly after use: After each use, PPE should be cleaned according to the manufacturer’s instructions, dried, and stored in a clean, dry environment to maintain its effectiveness for future use.
7. Train workers on proper PPE use: Ensure that all workers are trained on how to correctly select, wear, and maintain PPE, as improper use can diminish its protective value.
