What type of gas scenarios necessitate a Certificate of Fitness holder?

The necessity for a Certificate of Fitness holder particularly arises in scenarios involving torch operations with gas. This requirement is set forth because torch operations can involve the application of an open flame, which poses significant safety risks including the potential for fire, explosion, or exposure to hazardous gases.

Individuals who hold a Certificate of Fitness have undergone specific training that equips them with the knowledge and skills to handle hazardous situations related to gas usage, especially in torch applications. They are familiar with safety protocols, emergency procedures, and proper handling techniques for both gases and equipment, which is vital for preventing accidents in operational settings.

Other scenarios listed do not necessarily require a Certificate of Fitness holder due to the nature of the gas use involved. Cooking with gas, while it does involve potential hazards, is typically less risky than torch operations when proper residential equipment is used. Similarly, using gas for home heating is managed by appliances designed for safety and doesn't usually require specialized training for operation under normal circumstances. Lastly, operations in emergencies require general response protocols that might not entail a Certificate of Fitness, especially in non-torch applications.
