Who must hold a Certificate of Fitness when using oxygen with fuel gas containers?

The individual who must hold a Certificate of Fitness when using oxygen with fuel gas containers is the torch operator. This certificate ensures that the operator is trained and knowledgeable about the safe handling and operation of equipment that uses flammable gases.

The torch operator is responsible for performing tasks that involve the use of oxygen and fuel gas, such as welding or cutting. Holding a Certificate of Fitness signifies that the operator has received proper training on hazards associated with these gases, as well as understanding the necessary safety protocols and emergency procedures. This training is crucial in preventing accidents, such as explosions or fires, which can occur if the gases are not handled correctly.

In contrast, while site supervisors, gas suppliers, and safety inspectors play important roles in maintaining safety standards and providing resources, it is the torch operator who directly engages with the equipment and requires specific training and certification to perform their tasks safely. Their active role necessitates a clear understanding of how to manage and mitigate risks involved in using these gases.
