However, the <strong>appropriate response depends on the type of fire<\/strong> you are facing. This is where <strong>fire classification<\/strong> comes in: a simple yet fundamental system for identifying the <strong>nature of the hazard<\/strong> and selecting the appropriate <strong>extinguishing equipment<\/strong>.<\/p>\n\n<p class=\"wp-block-paragraph\">Indeed, not all fires are alike: a wood fire in a fireplace cannot be tackled in the same way as a deep fryer in flames or a burning gas leak. This is why fires are classified into <strong>standardised categories<\/strong> (A, B, C, D, F), according to the <strong>type of fuel involved<\/strong>.<\/p>\n\n<p class=\"wp-block-paragraph\">Here is why this classification is so important:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>It helps you <strong>understand how fire behaves<\/strong> (spread, temperature and residues).<\/li>\n\n\n\n<li>It helps prevent <strong>response errors<\/strong> (using water on an oil fire can make the situation worse).<\/li>\n\n\n\n<li>It indicates the <strong>right extinguishing agent<\/strong> to use (water spray, multipurpose powder, CO\u2082, etc.).<\/li>\n\n\n\n<li>It is the foundation of all <strong>fire safety training<\/strong>, both in the workplace and at home.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">Whether you are a private individual or a professional, knowing the fire classes means being able to <strong>respond effectively<\/strong> while protecting yourself and limiting damage. It is also the first step towards <strong>genuine fire prevention<\/strong>, whether in an office, workshop or family home.<\/p>\n\n<h2 class=\"wp-block-heading\">The 5 main fire classes: simple explanations and examples<\/h2>\n\n<p class=\"wp-block-paragraph\">Fires are divided into five main categories, each corresponding to a type of burning material. This classification makes it possible to identify the risk quickly and respond with the appropriate extinguishing equipment.<\/p>\n\n<h3 class=\"wp-block-heading\">Class A \u2013 Ordinary combustible materials<\/h3>\n\n<p class=\"wp-block-paragraph\">These are the most common fires. They involve materials such as wood, paper, cardboard, textiles and certain plastics. They can occur at home, in offices or in warehouses. These fuels produce embers and spread through heat.<br \/><strong>Suitable extinguishing equipment<\/strong>: water spray, foam, multipurpose powder.<\/p>\n\n<h3 class=\"wp-block-heading\">Class B \u2013 Flammable liquids<\/h3>\n\n<p class=\"wp-block-paragraph\">Petrol, solvents, paints, alcohol and hydrocarbons belong to this category. This type of fire is particularly dangerous because of the volatility of these products and the risk of explosion.<br \/><strong>Suitable extinguishing equipment<\/strong>: AFFF foam, multipurpose powder, CO\u2082.<\/p>\n\n<h3 class=\"wp-block-heading\">Class C \u2013 Flammable gases<\/h3>\n\n<p class=\"wp-block-paragraph\">This category includes fires involving butane, propane, methane and other gases used in industry or at home. Extinguishing such a fire always requires shutting off the gas supply\u2014never attempt to extinguish the flames alone.<br \/><strong>Suitable extinguishing equipment<\/strong>: powder, only after the gas supply has been shut off.<\/p>\n\n<h3 class=\"wp-block-heading\">Class D \u2013 Combustible metals<\/h3>\n\n<p class=\"wp-block-paragraph\">Less common but very difficult to control, these fires involve metals such as magnesium, aluminium and sodium. They mainly occur in industrial environments or laboratories.<br \/><strong>Suitable extinguishing equipment<\/strong>: special \u201cClass D\u201d powders only.<\/p>\n\n<h3 class=\"wp-block-heading\">Class F \u2013 Cooking fats and oils<\/h3>\n\n<p class=\"wp-block-paragraph\">Specific to kitchens, this class covers fires involving deep fryers or pans containing animal or vegetable fats. They are extremely intense and must never be treated with water.<br \/><strong>Suitable extinguishing equipment<\/strong>: a Class F wet chemical extinguisher or fire blanket.<\/p>\n\n<h2 class=\"wp-block-heading\">Which extinguisher for which type of fire? The practical guide<\/h2>\n\n<p class=\"wp-block-paragraph\">For an extinguisher to be effective, it must be suitable for the type of fire. Each extinguishing agent works according to a specific physical or chemical principle: cooling, smothering, interrupting the chain reaction or isolating the fuel. Choosing the right equipment is therefore essential for controlling a fire quickly and safely. <a href=\"https:\/\/safetyfirst.ch\/en\/catalogue-of-services\/fire-extinguisher-training-learning-how-to-respond-to-an-incipient-fire\/\">Discover our extinguisher training &gt;<\/a><\/p>\n\n<h3 class=\"wp-block-heading\">The different extinguishing agents<\/h3>\n\n<p class=\"wp-block-paragraph\">Several types of extinguishing agents are used in fire extinguishers. Each offers specific advantages depending on the situation:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Water spray<\/strong>: effective on Class A fires, it cools the fire and prevents re-ignition.<\/li>\n\n\n\n<li><strong>Foam (AFFF)<\/strong>: useful for liquid fires (Class B), it isolates the fuel from the air.<\/li>\n\n\n\n<li><strong>Multipurpose powder (ABC)<\/strong>: works by smothering the fire and interrupting combustion. It is effective on Classes A, B and C.<\/li>\n\n\n\n<li><strong>CO\u2082 (carbon dioxide)<\/strong>: recommended for electrical or liquid fires. It leaves no residue, but is not suitable for confined spaces.<\/li>\n\n\n\n<li><strong>Special agents<\/strong>: designed for metal fires (Class D) or cooking fires (Class F), they require dedicated equipment.<\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading\">Matching the right extinguisher to each fire category<\/h3>\n\n<p class=\"wp-block-paragraph\">An extinguisher\u2019s label always indicates the fire classes it can extinguish. Here are the most common matches:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Water extinguisher<\/strong>: Class A only.<\/li>\n\n\n\n<li><strong>Foam extinguisher<\/strong>: Classes A and B.<\/li>\n\n\n\n<li><strong>ABC powder extinguisher<\/strong>: Classes A, B and C \u2013 versatile and ideal for mixed-use buildings.<\/li>\n\n\n\n<li><strong>CO\u2082 extinguisher<\/strong>: Class B and energised electrical equipment.<\/li>\n\n\n\n<li><strong>Class D extinguisher<\/strong>: for metal fires only.<\/li>\n\n\n\n<li><strong>Class F extinguisher<\/strong>: for cooking oil and fat fires.<\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading\">Mistakes to avoid<\/h3>\n\n<p class=\"wp-block-paragraph\">Some inappropriate interventions can make the situation worse:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Using <strong>water on burning oil<\/strong> causes a violent flare-up.<\/li>\n\n\n\n<li>Spraying an extinguisher <strong>onto energised equipment<\/strong> without first checking its type can result in electric shock.<\/li>\n\n\n\n<li>Using an extinguisher that has <strong>not been inspected or properly maintained<\/strong> compromises its effectiveness.<\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading\">A closer look at eco-friendly and modern fire extinguishers<\/h3>\n\n<p class=\"wp-block-paragraph\">Fire extinguishers are evolving: some manufacturers now offer <strong>PFAS-free<\/strong> models (persistent fluorinated substances) to reduce their environmental impact. Others are innovating with <strong>water mist systems<\/strong> or connected extinguishers that can send an alert in the event of a pressure drop or non-compliance.<\/p>\n\n<p class=\"wp-block-paragraph\">Choosing an extinguisher also means considering its maintenance, service life and suitability for the installation location. A good extinguisher is only useful if it is properly selected, positioned and maintained.<\/p>\n\n<p class=\"wp-block-paragraph\">Thank you, let\u2019s continue with the next section in the same spirit. Here is the next section:<\/p>\n\n<h2 class=\"wp-block-heading\">Household fire extinguishers: what should you choose for your house or flat?<\/h2>\n\n<p class=\"wp-block-paragraph\">Even at home, a <strong>fire can start at any time<\/strong>. A short circuit, cooking left unattended, a candle placed too close to a curtain\u2026 Household risks are numerous. Having a suitable extinguisher is not a legal requirement in Switzerland for private homes, but it is an important <strong>fire prevention<\/strong> measure.<\/p>\n\n<h3 class=\"wp-block-heading\">Assessing common household risks<\/h3>\n\n<p class=\"wp-block-paragraph\">Before choosing an extinguisher, it is useful to identify potential sources of fire in your home:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Kitchen<\/strong>: the main place where fires start (fats, oils, ovens and electrical appliances).<\/li>\n\n\n\n<li><strong>Living room and bedroom<\/strong>: textiles, candles, chargers and cigarettes.<\/li>\n\n\n\n<li><strong>Basement or garage<\/strong>: storage of flammable products, batteries or electrical DIY equipment.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">Identifying these areas makes it easier to <strong>adapt your protection<\/strong>.<\/p>\n\n<h3 class=\"wp-block-heading\">Choosing a versatile and compact extinguisher<\/h3>\n\n<p class=\"wp-block-paragraph\">For household use, the ideal extinguisher is often an <strong>ABC powder<\/strong> or <strong>foam<\/strong> model:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>It covers Classes A and B (and sometimes C, depending on the model).<\/li>\n\n\n\n<li>It is easy to use and requires no complex maintenance.<\/li>\n\n\n\n<li>It is available in compact sizes (1 or 2 kg), which are convenient for discreet wall mounting.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">In addition, a <strong>fire blanket<\/strong> is strongly recommended, particularly in the kitchen.<\/p>\n\n<h3 class=\"wp-block-heading\">Where should it be placed for rapid intervention?<\/h3>\n\n<p class=\"wp-block-paragraph\">An extinguisher should be:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Visible and easily accessible<\/strong>, even in stressful situations.<\/li>\n\n\n\n<li><strong>Mounted near risk areas<\/strong>, without being too close to the potential fire.<\/li>\n\n\n\n<li>Installed at a <strong>height of between 1.0 and 1.5 m<\/strong> for quick access.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">Avoid cluttered or enclosed locations (cupboards, deep drawers), and make sure that <strong>everyone living in the home knows how to use it<\/strong>.<\/p>\n\n<h3 class=\"wp-block-heading\">Tips for safe use<\/h3>\n\n<ul class=\"wp-block-list\">\n<li><strong>Check the pressure<\/strong> once a year (the gauge should be in the green zone).<\/li>\n\n\n\n<li><strong>Never operate an extinguisher just to test it<\/strong>: this could reduce its effectiveness.<\/li>\n\n\n\n<li>If you have <strong>lithium-ion batteries<\/strong> (bikes, scooters or smartphones), find out about specific models suitable for this risk.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">At home and elsewhere, a properly chosen and positioned extinguisher can make all the difference in the event of an incident.<\/p>\n\n<h2 class=\"wp-block-heading\">Facing a fire: the right actions in an emergency<\/h2>\n\n<p class=\"wp-block-paragraph\">When a fire breaks out, panic can quickly take over. However, keeping calm and taking the <strong>right actions in the first few seconds<\/strong> can often limit damage and even save lives. Knowing how to respond when a fire starts is just as important as having an extinguisher.<\/p>\n\n<h3 class=\"wp-block-heading\">How should you respond when a fire starts?<\/h3>\n\n<p class=\"wp-block-paragraph\">Before taking action, you need to <strong>assess the situation<\/strong>:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Is the fire contained, or is it already spreading?<\/li>\n\n\n\n<li>Is there a <strong>safe escape route<\/strong>?<\/li>\n\n\n\n<li>Does the fire involve electrical equipment, a deep fryer or a gas line?<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">If the fire is small, contained and you have the appropriate extinguisher within reach, you can attempt to put it out. Otherwise, evacuation takes priority.<\/p>\n\n<h3 class=\"wp-block-heading\">When should you attempt to extinguish a fire? When should you evacuate?<\/h3>\n\n<p class=\"wp-block-paragraph\">An extinguisher is useful only if:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>The fire is <strong>at an early stage<\/strong> and accessible.<\/li>\n\n\n\n<li>You have <strong>the right type of extinguisher<\/strong>.<\/li>\n\n\n\n<li>You know how to use it.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">In all other cases, <strong>evacuate immediately<\/strong>, close the doors behind you to slow the spread of the flames, and call the emergency services as soon as possible. Remember that smoke kills more people than the fire itself.<\/p>\n\n<h3 class=\"wp-block-heading\">Using a fire extinguisher: 4 simple steps<\/h3>\n\n<ol class=\"wp-block-list\">\n<li><strong>Remove the safety pin<\/strong>.<\/li>\n\n\n\n<li><strong>Briefly test<\/strong> the extinguisher away from the fire.<\/li>\n\n\n\n<li><strong>Aim at the base of the flames<\/strong>, not at their tips.<\/li>\n\n\n\n<li><strong>Sweep from side to side<\/strong>, from left to right.<\/li>\n<\/ol>\n\n<p class=\"wp-block-paragraph\">Use short bursts if the extinguisher allows this, so that the charge is conserved in case the fire reignites.<br \/>Find out more in our <a href=\"https:\/\/safetyfirst.ch\/en\/how-to-use-an-extinguisher-effectively-a-practical-guide-to-acting-quickly-when-faced-with-fire\/\">practical guide to using a fire extinguisher<\/a>.<\/p>\n\n<h3 class=\"wp-block-heading\">The importance of rapid and organised evacuation<\/h3>\n\n<p class=\"wp-block-paragraph\">Every home or building should have a <strong>clear evacuation plan<\/strong>, even a basic one. At home, discuss it with the children: where to exit, where to meet and who to call. In businesses, <strong>fire safety training<\/strong> helps make these responses automatic and enables teams to act effectively together.<\/p>\n\n<p class=\"wp-block-paragraph\">The best intervention is always the one that has been prepared in advance.<\/p>\n\n<h2 class=\"wp-block-heading\">Why take fire safety training with SafetyFirst?<\/h2>\n\n<p class=\"wp-block-paragraph\">Having an extinguisher is not enough: you also need to know <strong>when and how to use it<\/strong>, often in a stressful situation. This is where fire safety training really proves its value. Learning how to respond to a fire means <strong>turning an instinctive reaction into a controlled response<\/strong>, with calm and efficiency.<\/p>\n\n<h3 class=\"wp-block-heading\">The benefits of practical, supervised learning<\/h3>\n\n<p class=\"wp-block-paragraph\">At SafetyFirst, <a href=\"https:\/\/safetyfirst.ch\/en\/catalogue-of-services\/fire-training-safety-equipment-and-instructions\/\">training in effective fire management<\/a> is designed to make every participant <strong>active and confident<\/strong>.
