Manitoba Security Guard Exam: Fire Safety (2026)

What a fire needs: the fire triangle

The manual builds the whole unit on one model. Three elements make up the fire triangle: fuel, air (oxygen), and heat, and all three must be present to start a fire. Remove any one and the fire cannot begin or continue, which is the principle behind every method of putting a fire out. Oxygen is almost always available, because the air we breathe is about 21% oxygen, so a fire rarely lacks the oxygen it needs. That leaves fuel and heat as the elements a guard can most realistically control through good housekeeping and hazard awareness. The manual defines the vocabulary carefully. Combustible means able to catch fire and burn easily. Flammable means burns quickly and easily, or likely to burst into flames. To detect is to notice or become aware of something, and vapours are wet gases, such as steam, that come off of a liquid. These definitions appear directly in exam questions.

Why fires are dangerous: smoke, not just flame

The manual makes a point that surprises many candidates: more people die in fires from smoke than from the flames themselves. Smoke disables before it kills. It lacks the oxygen a person needs to breathe, and it robs the brain of oxygen so that judgement, coordination and consciousness all fail; people become disoriented and lose consciousness. Smoke is black, so it takes away your sense of sight, causes your eyes to tear, and burns your lungs. The gases a fire gives off are dangerous in another way too. The transparent gases released when something burns are lighter than air, so they move very rapidly throughout a building, and they are also toxic, so they can kill quickly. Fire can also spread with terrifying speed through flashover, when a fire builds up heat and can instantly flash over into another room or space, shooting into any areas that are available. This is why the manual treats early detection and evacuation as life-or-death.

Being prepared before a fire starts

A guard's fire response is mostly decided in advance. Every site has an emergency plan, and no matter how simple or complex it is, the purpose is the same: to prepare people before an emergency happens. A simple emergency plan typically shows the location of emergency evacuation routes and firefighting equipment, and gives the names and contact numbers of the people in charge. A guard should have a copy of the fire safety plan and emergency procedures plan in their post orders or at their post, and read them carefully. If you do not understand something, keep asking questions until you fully understand your role. Preparedness also means physical housekeeping. Keep space between sprinkler heads and stored material, keep aisles, exits and fire lanes clear, and know how to operate all fire extinguishers and make sure they are ready to use. These are the tasks that turn a plan into an outcome.

Classes of fire and the PASS method

The manual's fire unit also teaches the classes of fire and the correct way to use a fire extinguisher, known as the PASS method, along with the types of fire extinguishers and the rules for when to try to put out a fire and when to leave it to the fire fighters. The app's question bank covers each of these in the manual's own terms so you can practise them directly. The essential fire-safety points to carry into the exam are:

• A fire needs all three elements of the fire triangle: fuel, air (oxygen) and heat.
• Smoke disables before it kills, and more people die from smoke than from flames.
• Keep a copy of the fire safety and emergency procedures plans in your post orders or at your post.
• Keep sprinkler heads, aisles, exits and fire lanes clear, and know how to operate every extinguisher.
