    Home Fire Safety Tips That You Need to Remember

    To illustrate the ingredients that a fire needs to initiate, fire safety experts have developed the fire triangle model. This gives handy tips for preventing home fires and keeping you safe.

    Fuel, oxygen and a source of ignition (heat) must be present for fire to exist. Once it has started, fire will produce a flame, smoke and heat.

    Smoke is made up of gases such as carbon monoxide (CO), carbon dioxide (CO2) and soot (small particles). The byproducts of fire are useful to detect the presence of fire. Most fire detectors will use one or a combination of heat, smoke, carbon monoxide or carbon dioxide to sense fire. 

    Fire safety experts consider the fire triangle to be very significant for two reasons:

    1. Fire Prevention – by keeping fuel, oxygen and heat apart, fire cannot start. And that is why we consider this as a very important fire safety tip at home.

    2. Fire fighting – by removing any of the elements when the fire has started, the fire will go out. Fire fighting is done by either removing oxygen,  e.g. by using some form of covering like powder or a gas that can displace oxygen like carbon dioxide.

    Another great tip to remember at your finger tips is the different types of fires. Experts have further classified fire based on the fuel type:  

    What Do the Symbols on a Fire Extinguisher Indicate?

    The symbols on a fire extinguisher help you quickly identify which types of fires it can tackle. Here’s a simple guide:

    1. Class A Symbol: Looks like a trash can with flames above it. This tells you the extinguisher is good for ordinary materials like wood, paper, and cloth.
    2. Class B Symbol: Depicts a gasoline can with a flame. It’s designed for flammable liquids such as gasoline, oil, and grease.
    3. Class C Symbol: Shows an electrical plug and outlet with a flame. This means it’s safe to use on electrical fires, and it won’t conduct electricity.
    4. Class D Symbol: Features a burning gear or metal. It’s meant for fires involving flammable metals like magnesium or titanium.
    5. Class K Symbol: Illustrated by a cooking pan on fire. This extinguisher is perfect for cooking oil and grease fires, especially in commercial kitchens.

    Each symbol guides you to choose the right extinguisher quickly, ensuring effective and safe use during emergencies.

    Table Summary For Classes of Fire

    Symbol on Fire ExtinguisherMeaning
    Class AFire is based on solid materials such as paper, textiles and wood.
    Class BFire is based on flammable liquids such as petrol, solvents and oil.
    Class CFire is based on gases such as methane, acetylene and propane. Electrical fires are classified here too.
    Class DFire is based on metals such as aluminum or magnesium.
    Class FFire is based on high temperature fats and cooking oils.

    Fuels for Class A, B and F can easily be found at homes. Hence, great care should be taken when storing such materials. The best location is away from sources of ignition or flames of fire.

    The classification also informs the type of fire extinguisher to be used to put out fire. Some of the fire extinguishers that are recommended for use at home can be found here. You should have one at least for your home, garage and car.

    The common causes of fire are electrical equipment, deliberate ignition, hot work involving a naked flame, carelessly discarded smoking materials, cooking appliances, heating appliances, unsafe use and storage of flammable liquids and gases. 

    Practice Your Fire Emergency Escape Plan

    Few people have actually implemented our next home fire safety tip. Which is having a fire emergency escape plan that is known and practiced by all family members. All emergency exits must be known and tested from time to time and kept free from obstacles. You can invite your fire department to help you in this.

    Remember fire cause immense damage to homes and house contents. Items not directly destroyed by the fire are seriously affected by smoke. If you are insured, these losses can be recovered.

    However the consequences to people are irreversible. Most people killed are not killed by the flames directly but by smoke or carbon monoxide inhalation. Serious burns may also occur.

    Install Smoke Detectors

    This brings us to the last home fire safety tips: It is highly recommended that you install smoke detectors in your home, house or premises to keep safe. The early warning of fire makes a huge difference.

    One more safety tip: Regularly test your smoke alarms and never ignore a smoke alarm going off. Always check and if you experience false alarms consistently, it is time you replaced your smoke detector. You can get further guidance here.

  • First Alert Model 9120B Review

    First Alert Model 9120B Review

    This model of smoke detector is hard wired and comes with a 10 year limited warranty. First Alert 9120B is very affordable.

    It is an improvement from the previous 9120 with better performance and ease of installation.

    first alert 9120b review

    This is a great choice for a smoke alarm, especially if you are looking to quickly detect flaming fires.

    The engineering design uses the ionization sensing technology that is very ideal at detecting flaming fires unlike photoelectric sensing technology that is most suitable for smoldering fires.

    First alert smoke alarms meet UL smoke detector standards.

    First Alert 9120B Features

    What actually makes this model different from its predecessors? To begin with, the size and weight are almost the same with 9120.

    However, the First Alert 9120B comes with standard battery backup. This definitely ensures that you are covered in case of mains power outage.

    To replace the battery, simply slide the drawer on the sides, you do not have to un-mount the whole alarm. Of course, this is feature most of us appreciate for convenience.

    Both 9120 and 9120B models have universal mounting brackets to make installation and replacements faster and easier.

    They also have a test or silence button tamper resistant locking pins as well as latching alarm indication.

    Since First alert 9120B was developed after 9120, it is more accurate and does a better job to suppress nuisance alarms.

    Having compared the two First Alert models 9120 and 9120B, you should also be aware that there are newer versions of this model available in the market as well.

    These two are: SA9120BCN smoke alarm and

    First Alert SA9120BPCN. These new models are improvements on the First Alert 9120B.

    First Alert 9120B6CP Smoke Alarm


    This model is slightly heavier than SA9120BCN.

    It has all the features of SA9120BCN but the differentiating feature is the additional adapter plugs that are meant to make easier the replacement of smoke alarms not manufactured by First Alert.

    First Alert SA9120BCN Smoke Alarm Hardwire with Battery Backup

    It has similar dimensions as the 9120B but slightly heavier.

    It is hard wired to 120V ac mains power and has a battery backup of 9V, just like the 9120B.

    It has the rest of the features available in 9120B but in addition this type can interconnect with up to 12 other first alert hard wired alarms.
