Current affairs Training and management


Another important consideration is the person(s) nominated to authorise hot work. They must have experience and training in the challenges associated with hot work, and be of suitable status to ensure compliance with the procedures and prevent or stop the work if they have any concerns. Prior to work commencing, the management system should be adhered to, and a hot work permit must be obtained from the authorised person. Experience shows that a satisfactory level of management, care and supervision is far more likely to be achieved where a formalised management and written permit system is in force, and under a competent supervisor who also has the authority to ensure compliance with the fire procedures. All hot work procedures should only ever be carried out by appropriately trained personnel who are aware of the hazards posed, and only equipment which is in good condition should be used in accordance with the manufacturer’s instructions. Training should address being able to identify issues with equipment and hoses, gas cylinders, tar barrels and their adequate support, etc.


In the case of oxy fuel welding, acetylene


– an extremely flammable gas that is unstable and liable to decomposition at elevated temperatures and pressures – is still widely in use, but should be avoided if at all possible. Acetylene in cylinders presents a unique


firefighting hazard, and can form an explosive atmosphere in the presence of air or oxygen from cylinders. When the use of acetylene cannot be


avoided, great care must be taken in its use, storage and handling. In a fire situation, the fire service can create a hazard zone radius, typically of 200m, where acetylene cylinders are exposed. Training to understand these risks should be provided. Finally, fire and hot work awareness training should be provided to all individuals on any site and this needs to include having the knowledge to raise a flag when something is seen that is not right or is being completed incorrectly. The eyes and ears of many on the ground can stop an unsafe act that could cause a fire.


Fire watch


A formal, dedicated and trained fire watch is needed throughout the hot work job and for a period of time after the work has finished. This may consist of than one person, depending on the task, and the exposure and topography of the work space. An adequate and continuous, trained fire watch is critical both during the work and for a period following its completion. It is the back stop if something goes wrong. The trained person(s) who completes the


monitoring should have at least two appropriate fire extinguishing appliances to hand at all times, and be trained in their selection and use. Both the trained persons completing the hot
