Common Questions About Fire Extinguishers Answered
You are probably familiar with fire extinguishers. You see them around all around you, and you know they are an important tool in extinguishing small fires. But if you are a building owner or facility manager, there is a lot more you need to know about keeping your extinguishers in working condition.
Here are some everyday questions about keeping your extinguishers in top condition.
Is there any danger in dropping a fire extinguisher?
Yes. First of all, most of the fire extinguishers you see are pressurized vessels. A typical ABC rated dry chemical fire extinguisher is pressurized to around 185 to 195 PSI. A CO2 extinguisher is pressurized to about 2000 PSI. Damage from dropping can damage the integrity of the extinguisher, so it is very important that you keep the dropped fire extinguisher in a safe and isolated area. Contact a fire equipment service company to handle it.
Dropping the extinguisher can also result in the pickup tube breaking, which would render the equipment useless. To the untrained eye, this can go unnoticed.
So if you knock an extinguisher off its wall hook, do not just place it back. Make sure it is reported to your fire equipment services company.
Why is the fire extinguisher pin sealed?
How often must a fire extinguisher be inspected?
Can all extinguishers be used for any type of fire?

Do You Know How To Use Your Fire Extinguisher
Many people have a fire extinguisher, but they may not have the slightest idea when it comes to using one. Everyone should have at least one fire extinguisher at home, but its just as important to ensure you have the proper type of fire extinguisher. Fire protection experts recommend that you have three extinguishers in your home. One for the kitchen, one for the basement and one for the garage. If theres a fire, get everyone outside and have someone call the fire department. Only then should you attempt to fight a small fire. If the fire becomes large, get out. Fire extinguishers are designed to put out small fires, not large ones.
The ABCDs of fire extinguishersFire extinguishers are divided into four categories, A, B, C, or D, based on different types of fires. The following is a quick guide to help choose the appropriate extinguisher for the right type of fire.Class A;extinguishers are for ordinary combustibles materials such as paper, wood, drapes and upholstery.Class B;extinguishers are for flammable and combustible liquids such as fuel oil, gasoline, paint, grease in a frying pan, solvents and other flammable liquids.Class C;extinguishers are for electrical equipment such as appliances, wiring, overheated fuse boxes, conductors, and other electrical sources.Class D;extinguishers are for metals such as magnesium, potassium and sodium, and are commonly found in a chemical laboratory.

What To Do Before Creating A Fire Escape Plan
As mentioned earlier, a fire escape plan varies in almost all situations, and therefore the following points must be kept in mind while creating one:
- Understand the Structure
The structure of the building is the first thing you must understand. Having a blueprint would be helpful. With a good understanding, it would be easy for you to identify the safe places in the construction, and you will finally end up having an effective fire escape plan for the people.
- Actions and their Sequence Upon Discovery
Being a security person, while creating an escape plan, you must define what action must be taken when the fire breaks and in which sequence should they be followed. It is also imperative to ensure that everyone in the staff is well-aware of these steps in order to get out of the place without getting hurt.
- First Aid and Fire Extinguishers
Have several first aid boxes and fire extinguishers installed in your office so the people can get elementary resolution if need be.
You must install the emergency calling points at various places in the office and make sure that they are easily accessible in case of emergency. You must understand that you might not necessarily be always nearby, and therefore the staff people must be educated upon how to use those calling points to call the fire brigade before leaving the premise.

Do You Know All You Need To Know About Smoke Alarms
Install at least one smoke alarm outside each sleeping area, and on every level of your house. Make sure to change the batteries in all smoke alarms twice a year . Also, it is important to test and clean your smoke alarm on a regular basis. Test your smoke alarm monthly by pressing the test button and holding until the alarm sounds. While you dont have to clean your smoke alarm as often as you test it, it is important to do so every six months. To clean, open the cover and gently vacuum the interior of it. Put the cover back and make sure the alarm is working. The lifespan of a typical smoke alarm is about 10 years, but some may last as little as five years, that is why it is so important to test it on a regular basis.

Choose The Right Fire Extinguisher
The first thing you need to know is the different classifications of fires, and the second that not all fire, you need to understand what types of fires you may have to deal with and make sure your extinguisher can get the job done.
Most household fires fall into one of the following categories:
Class A: These fires are fueled by solid combustibles like wood, paper, and cloth.
Class B: These fires are fueled by flammable liquids such as oil, petroleum, and gasoline.
Class C: These fires are started or fueled by faulty wiring, fuse boxes, and appliances.
Class K: These fires are started or fueled by cooking oils and greases, animal fats, and vegetable fats.
All fire extinguishers are labeled to indicate which classes of fire they are designed to combat. Most household fire extinguishers are considered multipurpose and labeled for use in A, B, and C classes. Class K extinguishers are heavier duty and will need to be bought separately. We suggest this 6-liter extinguisher, as it best fits the Fire Department Connections recommendation.
Fire extinguisher labels also include symbols to indicate which types of fires the extinguisher is designed to fight. If there is a circle and a red slash through any of the symbols, that indicates that the extinguisher cannot be used to fight that type of fire.
Household fire extinguishers are also rated for the size of fire that they can safely handle. The higher the rating , the larger the fire the extinguisher can put out.

Fire Extinguisher Recharging: What Everyone Should Know
We tend to think of fire extinguishers as constants theyre always nearby, ready and waiting in case a fire breaks out. But the truth is that fire extinguishers often are not ready, because they havent been properly maintained. There are countless stories of people attempting to fight an incipient-stage fire with a portable extinguisher only to discover too late that the extinguisher is not charged even if it has never been used before.
Everyone from homeowners to business owners needs to understand the importance of fire extinguisher recharging. This process is an important aspect of fire extinguisher service and maintenance, and cannot be ignored.
What Is The Fire Extinguisher Recharging Process
Fire extinguisher recharging should be performed by a trained professional. Fire protection companies have the tools, training and knowledge to ensure that your fire extinguishers are in peak working condition and that they have been properly refilled with the correct extinguishing agent.
Here is what you can expect when your fire extinguisher is recharged. This is not a guide for how to recharge a fire extinguisher, but an overview so that you can understand the process.
One of the simplest ways to help protect your home or business from incipient-stage fires is to ensure your fire extinguishers are properly charged and maintained.

When And Why Do Fire Extinguishers Need To Be Recharged
There are several instances where fire extinguisher recharging needs to take place one that is obvious and some that are less commonly known.
- Fire extinguishers need to be recharged immediately after each use. Even if the extinguishing agent inside was not completely discharged, the extinguisher still needs to be serviced in order to make sure its ready for its next use. Even a minimal discharge will normally result in leakage and an eventual total loss of pressure needed for proper operation.
- Fire extinguishers need to be recharged periodically throughout their life, even if they havent been used. Both the NFPA 10 code standard for portable fire extinguishers and manufacturers service guidelines require periodic internal examination and recharging. For the most commonly used stored pressure dry chemical fire extinguishers, this internal examination and recharging is required at six and twelve years from the date of manufacture noted on the extinguisher.
- Extinguishers can also need to be internally examined or recharged due to damage or other environmental factors that may result in them becoming depressurized.
Vandalism And Extinguisher Protection
Fire extinguishers are sometimes a target of vandalism in schools and other open spaces. Extinguishers are occasionally partially or fully discharged by a vandal, impairing the extinguisher’s actual fire-fighting abilities.
In open public spaces, extinguishers are ideally kept inside cabinets that have glass that must be broken to access the extinguisher, or which emit an alarm siren that cannot be shut off without a key, to alert people the extinguisher has been handled by an unauthorized person if a fire is not present. This also alerts maintenance to check an extinguisher for usage so that it may be replaced if it has been used.

Tips For Making A Fire Escape Plan
A couple of tips that you should follow while making a fire escape plan include:
- Use globally recognized standard symbols, and do not try to beautify or otherwise modify them to make them look attractive. Remember, you are preparing an evacuation plan to save lives and not a presentation to impress the clients or customers
- Always label the symbols clearly and with the large text so they can be read even from a distance
- Make sure to distribute a copy of the fire escape diagram to all the staff members, and also paste them on the walls wherever needed
- Clearly mark the current location at several places on the map/plan to help the readers understand the closest point of help or escape
Do You Have A Fire Escape Plan
Every household in Canada should have an emergency plan in order to react quickly if a fire were to occur. Draw up a floor plan of your home showing all possible exits from each room. If possible, plan two exits: a main route and an alternate route from each room. Identify a safe place where everyone should meet. Practice the plan with your family and make sure every member knows what to do.

Condensed Aerosol Fire Suppression
Condensed aerosol fire suppression is a particle-based form of fire extinction similar to gaseous fire suppression or dry chemical fire extinction. As with gaseous fire suppressants, condensed aerosol suppressants use clean agents to suppress the fire. The agent can be delivered by means of mechanical operation, electric operation, or combined electro-mechanical operation. To the difference of gaseous suppressants, which emit only gas, and dry chemical extinguishers, which release powder-like particles of a large size condensed aerosols are defined by the National Fire Protection Association as releasing finely divided solid particles , usually in addition to gas.
Whereas dry chemical systems must be directly aimed at the flame, condensed aerosols are flooding agents and therefore effective regardless of the location and height of the fire. Wet chemical systems, such as the kind generally found in foam extinguishers, must, similarly to dry chemical systems, be sprayed directionally, onto the fire. Additionally, wet chemicals are dissolved in water, whereas the agents used in condensed aerosols are microscopic solids.
