Fire safety is an important aspect to talk about. Protecting buildings and public areas is part of this aspect. Keeping these places away from fire needs the safe use of a fire extinguisher. This is a safety tool that can manage and keep people safe from further damage. Still, having a fire extinguishing unit does not cut it. Knowing how to use it properly can be the lifesaving solution between small harm and a catastrophic catastrophe.
By going over the different kinds on hand, the PASS technique, typical errors, and the need for regular fire extinguisher maintenance, this blog will guide you on the correct way of using a fire extinguisher.
Different Fire Extinguishers and Their Purposes
Not every fire is identical; neither is every fire extinguisher. Safety and efficacy depend on selecting the right one for the nature of the fire. Using a fire extinguisher correctly is just as important. These are the main categories of fire extinguishers and their purposes:
1. Water (Class A) Extinguishers.
Fires burning typical fuels like wood, paper, and fabrics would best be tackled with water. They work by reducing the temperature of the fuel below its ignition point. Still, they are inappropriate for fires of electrical or combustible liquid nature.
2. Class A and B Foam Fire Extinguishers
Versatile, foam extinguishers work on Class A (combustibles) as well as Class B (flammable fluids like paint or petrol) fires. The foam forms a wall, cutting down on vapors and lowering the temperature of the fire.
3. CO2 Extinguishers.
Great for burning liquid fires (Class B) and electrical fires (Class E), CO₂ extinguishers displace oxygen to suffocate the flames. They are great for use around electronics since they do not leave a residue.
4. Dry Powder Extinguisher
A dry powder fire extinguisher will work on Class A, B, and C fires (flammable gases). Some are rated for electrical fires. But they can impede breathing and cause visibility problems, hence they are usually prescribed for outside use.
5. Wet Chemical Extinguishers
These extinguishers use a chemical solution to cool and suffocate the fire, especially made for Class F fires (cooking oils and fats). Commercial kitchens are where they are usually seen.
Knowing these distinctions guarantees that when the moment comes to employ a fire extinguisher, the correct one is chosen for the scenario.
The PASS Technique: The Right Way to Employ a Fire Extinguisher
The PASS procedure, a common technique in fire extinguishing methods, is the most frequently advised way of operating a fire extinguisher. In an emergency, this straightforward four-step approach is easy to recall and very useful.
This is the definition of PASS:
P Stands for Pull
This breaks the tamper seal and lets the fire extinguisher be released.
A for Aim Small
Point the nozzle or hose toward the source of the fire. Hitting the flames won’t do much; aiming the fuel source is what puts out the fire.
S for Squeeze the Handle
This let the extinguisher chemicals out. Maintain a strong grip and constant force for a uniform result.
S Stands for Sweep from Side to Side
Sweep the nozzle across the fire’s base till it seems to be gone. Keep spraying in order to prevent rekindling.
Memorizing and applying this technique will let you respond under stress softly and swiftly.
Step-by-Step Instructions on How to Handle a Fire Extinguisher in an Emergency
Though the foundation is offered by the PASS approach, here is a more thorough road map to enable an effective response in an actual crisis:
1. Examine the Fire
A fire extinguisher will not control every fire. As part of your emergency preparedness, evacuate at once and contact emergency services if the fire is raging fast, generating dense smoke, or threatening to trap your exit.
2. Select the Appropriate Extinguisher
You need to use the right kind of fire extinguisher to manage the fire. If you use the wrong fire extinguisher in case of a fire caused by electricity, things can go haywire. A fire extinguisher sizes chart can also help you choose the appropriate extinguisher based on the area and fire risk.
3. Put Yourself Safely
Generally, about 6 to 8 feet apart, keep your back to a clear exit, and keep the fire some distance away. Never let the fire come between you and your avenue of escape.
4. Operate the Extinguisher with PASS
Use the PASS method: Pull, Aim, Squeeze, and Sweep. Approach closer as the fire decreases, but carefully.
5. Keep the Area Under Observation
Even when the fire is doused, one needs to remain vigilant of the place fire happens. Some fires can recur, especially if it is a grease fire or the fire induced by inflammable liquids.
6. Call the Fire Department
Even if you put out the fire, it is a good idea to get professionals to visit the site. There can be hidden hotspots that can cause damage.
Avoid These Common Blunders When Employing a Fire Extinguisher
Common blunders when responding to a fire emergency may be hazardous. Avoid these usual mistakes:
- Panicking and forgetting the PASS Technique: Preparation and drills keep you calm. Panic typically results in incorrect application.
- Getting the Wrong Extinguisher: Water on an electrical or grease fire will produce an explosion or electric shock. Be familiar with your extinguishers.
- Pointing at the Flames Rather Than the Base: This is useless. Always point at the base of the fire.
- Standing Too Close or Standing Away Too Far: Being too close is unsafe, and standing away too far will decrease the effectiveness of the extinguisher.
- Turning Away Too Quickly: Fires can reflash. Always check that the fire is out before turning away.
Employee and household member education about how to use fire extinguishers can prevent these errors.
How to Properly Maintain Your Fire Extinguisher
Regular maintenance means your fire extinguisher will work as expected when necessary. Here is what to do:
1. Monthly Visual Checks
Check for signs of damage, rust, leakage, or broken seals. Make sure the pressure gauge is in the green area.
2. Annual Professional Inspection
Have a certified technician inspect and service the extinguisher. This is a critical component of fire extinguisher service and maintains safety standards.
3. Shake or Invert (If Applicable)
Certain extinguishers (such as dry chemical types) are helped by periodic shaking to keep the powder from settling.
4. Check the Hose and Nozzle
Make sure the hose is clear and the nozzle is free. Clogs or damage can hinder performance.
5. Maintain Accessibility
Place the extinguishers in a visible place that would not obstruct the view. The location should be communicated to everyone.
Routine check-ups of fire extinguishers ensure smooth operation aligned with legal and insurance regulations.
When Does a Fire Extinguisher Need to Be Replaced?
Nothing lasts forever; as part of proper fire extinguisher replacement, one should know when it is time to replace the fire extinguisher.
- After Use: Even if you only partly used it, most fire extinguishers have to be replaced or recharged after use.
- Ducts that can be seen: Cracked, dented, rusting, or deteriorated parts suggest that the extinguisher won’t operate effectively.
- Failed Inspection: A professional fire extinguisher service expert will tell you to replace the unit if inspection shows that such action is advisable.
- Expiration of Fire Extinguishers: Typically, 5 to 15 years, fire extinguishers expire. Do fire extinguishers expire? Yes—refer to the manufacturer’s tag or serial number for the expiry date.
- Inoperative Pressure Gauge: If you find out that the pressure gauge is leaking or cracked, replace it immediately.
