Understanding the Workplace Fire and Types of Fire Extinguishers

The very first step in selecting a proper fire extinguishers for your home, car or workplace, here we will discuss some common fire extinguishers, types and what kind of fires they're best suited for. Before we talk about the types of fire and fire extinguishers though it's important that you understand how fire actually works. Essentially there are three main elements that must be present for a fire to come in existence, and these elements include oxygen to sustain combustion, heat to raise the material to its ignition temperature, and fuel to support the combustion. When these elements combine, it creates a chemical reaction which can cause fire, in order to extinguish any fire, you must remove at least one of these four elements as we go over the different types of fire extinguishers you will see and how they each work differently based on the type of fire you're fighting.

Types of Fire Extinguisher and their uses-

Water-Fire Extinguisher and Water with additive Fire extinguishers are all color-coded Red on the extinguisher description panel. Basic Instructions on how to operate them are printed on the canister. You should only use them on flammable solids like wood, paper, textiles, and furnishings. It can be very dangerous to use them on other types of fire.

Carbon Dioxide or CO2 Fire Extinguishers are color-coded black on the extinguisher description panel and operating instructions can be found on the canister. Although Carbon dioxide extinguishers are primarily for use on flammable liquid fires like petrol, oils and petroleum-based spirits, we also recommend them for fires in electrical and electronic equipment as the CO2 gas won’t damage your computer or gadgetry. As the gas discharge is extremely cold avoid handling the special discharge horn when using.

Foam Fire Extinguishers are color-coded cream on the identification panel and again carry basic operating instructions. Larger sizes normally have an extension hose and low-pressure nozzle. They are intended for use on flammable liquids like petrol, oils and solvents. As they are water-based they also extinguish flammable solids like wood, paper and textiles.

Dry Powder (DCP) Fire Extinguisher are color-coded blue and are available in a wide choice of sizes and are very versatile. You can use them on fires involving flammable solids, flammable liquids, and also flammable gases such as propane and butane. They also work on fires caused by electrical equipment but unlike CO2 the powder sets under heat so can leave a sticky residue.


Wet Chemical Fire Extinguisher is color-coded yellow on the identification panel. They contain a special chemical formulation that reacts with cooking fat and cooking oil fires to extinguish the fire so are a must for the commercial kitchen. You can now buy special foam formulations that are effective on cooking fat fires in smaller canisters for home use. 

Ball Fire Extinguisher is a new type of A, B & C fire extinguisher comes in a shape of ball, the main function of ball fire is very simple, just through the ball fire in the middle of fire, the ball fire self-detonates and explodes within 3 to 5 second and spread non-toxic chemical to extinguish the fire.

P.A.S.S Method for using a fire extinguisher-

Workplace Fire and Types of Fire Extinguishers
Every company is going to have someone in charge of checking these visually on a monthly basis every year, you’ll have them sent the way to be checked by the professionals but the monthly checks are pretty simple. Let’s make sure that they're charged, let’s make sure all the parts are in place that the hose is in good condition, they’re mounted in the right place. It's easy to lose track of one of these things if they get used, make sure it gets put back, gets recharged because you never know when you're going to, need to use one if you happen upon a fire that is small enough for you to actually fight with. One of these smaller fire extinguishers all you have to remember is the acronym PASS. PASS helps us learn how to use this thing safely and not forget it when our mind is being preoccupied by the blaze P is for pole we’re going to pull the pin, the pin is here to make sure that this thing doesn’t accidentally get discharged it’s really the only thing that's stopping the two levers from coming together and discharging the unit. When we pull the pin make sure we're not squeezing together we're just holding on the underside it should be pretty easy to pull. It should have some sort of at ether on it or maybe a plastic band. discard both of those things and that’s what we're going to go ahead and grab this nozzle and move on to our next letter grab this nozzle we're going to aim at the base of the fire, stay a nice safe distance away and S is for squeeze when we squeeze this handle will discharge the unit and the last thing we're going to do is sweep we're going to sweep at the base of the fire and try to put out the flames from the base of the fire.

The Importance of Adequate Welfare Facilities on Construction Sites: Roles, Responsibilities, and Consequences

Image
  In construction, the quality of on-site working conditions plays a crucial role in shaping productivity, safety, and worker morale. Among the key elements contributing to a positive and functional work environment are welfare facilities which is an often overlooked yet critical aspects of occupational health and safety. Unfortunately, many construction sites still fall short in offering adequate welfare provisions, which not only undermines workers' well-being but also triggers behavioral issues that escalate tensions between workers and supervisors. This blog delves into how poor welfare facilities can negatively affect workers, explains what employers are responsible for, highlights the advantages of offering proper amenities, and sheds light on the risks of failing to meet workers’ basic needs. Inadequate Welfare Facilities and Their Behavioral Impact Construction work is physically demanding, stressful, and often conducted in challenging environmental conditions. When ...

Driving Safety in Industrial Settings Matters

Image
  When we talk about safety at work, things like hard hats, machine guards, and lifting the right way usually come to mind. But there’s another big one that sometimes flies under the radar— safe driving inside the plant . Whether you’re behind the wheel of a forklift, a company truck, or even your own car on-site, driving defensively here is just as important as out on the road. After all, nobody wants a close call (or worse) when we’re just trying to do our jobs. Why Driving in the Plant is Different Let’s be real—plant driving isn’t like cruising down the highway. It’s a whole different ballgame: Tight spaces with little room for error People walking everywhere (sometimes in a hurry) Equipment moving around, sudden stops, and blind corners Noise and distractions that can make it hard to stay focused That’s why  defensive driving  isn’t just a nice-to-have here—it’s a must. It’s not just about following rules; it’s about staying sharp, expecting the unexpected, and makin...

Office Ergonomics-Contact Stress: This Is What Professionals Do

Image
  Contact Stress- Contact stress results from occasional repeated or continuous contact between sensitive body tissue and a hard or sharp object contact stress commonly affects the soft tissue on the fingers, palms, forearms, thighs, calves and feet. Prolonged contact stress can inhibit blood flow, tendon and muscle movement and nerve function. One common example is resting wrists or elbows on the sharp edge of a desk or workstation, while performing tasks this can take place, while typing with the keyboard either too close or too far away using the mouse for a prolonged period of time can also lead to contact stress. The stress can be prevented by repositioning commonly used workstation items floating hands above the keyboard and reducing tension in the shoulders eliminates potential contact stress using a keyboard tray eliminates contact with a work surface edge and keeps your arms in a neutral position. Optimal neutral arm position has the arms relaxed at the side of the body wi...

The Respiratory System of Human Body

Image
  We are going to discuss about the respiratory system in this article. One of the most vital organ systems of our body is the respiratory system. We breathe about 16,000 to 24,000 times per day, which exchanges about 11,000 liters of air with the atmosphere in this process. The oxygen of the atmospheric air is delivered to the human body, which is then utilized by all the tissues, and the carbon dioxide which is produced by the human body is exported to the lungs and then exchanged with the atmospheric air, In this article we will first talk about the brief anatomy and physiology of the human respiratory system and then we will discuss how the gas transport to the alveoli occurs, we will talk about how the human respiratory system works together with the circulatory system and then we will talk about how the gas exchange happens in the alveoli.   So, first coming to the anatomy and physiology of the human respiratory system, the vocal cords present in the larynx divide th...

Questions That Can Help to Define Confined Space Safety | Health and Safety

Image
More than two million workers work in confined spaces every year . Each of those spaces has unique hazards and risks that the worker must address. From hazardous atmospheric conditions to biological hazards and potential combustible materials, safety professionals have much to consider before workers enter confined spaces. Answering a couple of key questions can help you make sure that workers stay safe in confined spaces. What Is a Confined Space? To effectively address the hazards that workers face in confined spaces, you need to become aware about the terminology. This starts with an understanding of what a confined space is and how such an environment differs from other conditions that workers may encounter. OSHA definition of confined space: 1. The area is large enough and so configured that an employee can bodily enter and perform assigned work. 2. The area has limited means for exit and entry (e.g., tanks, vessels, silos, storage bins, hoppers, vaults and pits...
