- 2. Intended for anyone who may work around Hot Work tasks but are not doing hot work themselves Objectives: 1. Know what Hot Work is 2. Know how Hot Work could create fires 3. Know when to use a Hot Work Permit 4. Check your understanding 7/21/2022 2 Hot Work: Affected Employee
- 3. •Bringing ignition source into an area containing combustible and flammable materials What is Hot Work? 3 7/21/2022 Ignition Source + Fuel = Fire
- 4. What are ignition sources? Think FISH: Friction. Rubbing objects together can generate enough heat to ignite solvents Impact. Some materials can be ignited just by hitting them hard enough. This can also cause sparks. Static. Electrical power, static, batteries Heat. Heaters, grinding sparks, etc

Editor's Notes
- Welcome! This training is intended for anyone who may work around someone doing Hot Work. You’ll learn what Hot Work is and why it’s so important to control it. There will be a short test at the end.
- Here’s what we call the Fire Triangle. As you can see, fires need 3 things to burn. Oxygen from the air, fuel (something that will burn), and a source of ignition (something with enough energy to ignite the fuel). Remove any one of these and we cannot have a fire. Oxygen is very hard to remove because it’s in the air and there are many things in our workplaces that can burn, so we do everything we can to prevent uncontrolled ignition sources. However, what do we do when we need to bring an ignition source into the workplace to do a job like welding, grinding, or take photographs? That’s when we use the term “Hot Work” and use a Hot Work Permit to manage the ignition source and fuel.
- Ignition sources are anything that can cause enough energy to cause a fire. Think FISH: Friction generated when rubbing objects together can create a hot of heat. Impact can cause sensitive materials such as dry nitrocellulose to ignite. Static, and other electrical sources, can create sparks. Lastly, Heat describes many other hot items which could ignite materials.
- It’s very hard to remove oxygen because it’s present in the air, and to perform the hot work we’ve deliberately brought in an ignition source. Since we have oxygen, and a source of ignition, then we can have a fire unless we remove or control the fuel. We manage this by using a Permit. The Permit also describes other measures that prevent a fire from spreading such as use of fire extinguishers. With no fuel, we cannot have a fire.
- A Hot Work Permit is needed when bringing any ignition source within 11 meters, or 35 feet, of something that could burn. This includes most areas inside a plant, but also include labs, offices, or outside near tanks, pipes, and even vegetation. In addition, we need a Permit if taking unrated electrical equipment such as cell phones into areas containing solvents and combustible powders – also known as classified areas. These are normally marked with an EX sign or similar, or Class 1 or 2 Division 1 or 2, or Zone 1 or 2.
- We don’t need a Hot Work Permit if doing work in an area specially designated as a Hot Work Area, such as a welding room. We’ve already removed the fuel in these. We also do not need a Permit if the work is done more than 11 meters, or 35 feet, from sources of fuel.
- As already mentioned, a Hot Work Permit focuses on controlling fuel. It removes fuel or protects it so that there’s no chance the ignition source can cause a fire. It also makes sure no operations are taking place nearby that could create fuel while the work is being done. The Permit requires checking the immediately area around the job for 4 hours after it’s complete to make sure there’s no smoldering embers that could cause a fire. As you would expect, the Permit is signed by a senior manager to make sure that it includes everything it needs to and to make sure it’s followed.
- Even if you’re not mentioned on the Permit, it’s important you understand what’s going on so you don’t accidentally introduce fuel into an area the Permit has worked so hard to control. Talk with the person doing the work or your supervisor if you have any questions.
- Here are two questions to check you were paying attention! First question. Which of the following is considered Hot Work? Taking a normal cell phone into a classified area? Welding? Grinding? Or all 3 of these? The answer is D: All of the above. The Permit will make sure the ignition source is controlled and fuel removed.
- Question 2: Are you authorized to do Hot Work yourself after going through this Awareness training? Yes; or B: No. The answer is B: No. To do Hot Work, or put your name onto a Hot Work Permit, you must go through the full Hot Work Authorized Person Training. Talk with your supervisor if you think you need this.
- This is the final slide. You’ve learnt what Hot Work is and why it’s so important to manage ignition sources and fuel in the workplace. We do that by requiring a Hot Work Permit to be filled out every time we bring an ignition source into the workplace. Please direct any questions to your EHS Manager. Thank you!
