Environment considerations today tend to control, guide and develop engineering processes affecting both men and environment. The melting of filler metal, base metal and the coating on base metal during welding processes and subsequently the gases formed release minute, solid particles into the air creating a plume and is called welding fume.

In most countries there is extensive legislation assigning responsibilities to employers to take reasonable care of the health and safety at work of their employees e. Welding is associated with several hazards to health and safety, and the employer needs to be able to ask informed questions:. The employer needs to ensure that the lighting conditions are adequate for the work undertaken - giving extra lighting where necessary. Welders stand for long periods of time, since they must keep a very steady hand position, and this means that they can become quite cold if the workshop is not sufficiently well heated. Conversely in hot weather, the environment can become unbearably hot, and the welder has not got the option of removing clothing. Both overheating and underheating can cause fall in comfort, efficiency and productivity. Housekeeping is extremely important to avoid slips, trips and falls, damage to equipment and fire.

The purpose of this policy is to provide safety requirements for welding, cutting and brazing. This policy applies to all employees, students, faculty and contractors who may perform welding, cutting, or brazing in their job functions. The metal does not reach its melting point. Instead, filler material and flux from a welding rod melt to form the weld. Fire Watch: Trained personnel who are in attendance during the entire cutting and welding operation and are immediately available to extinguish a fire or take other effective action if necessary.

Welding, for the purposes of this guideline, is the industrial process for making welds to join metals. Allied processes also involve metals and are somewhat similar with respect to the hazards created, they include gouging, cutting or grinding metal or otherwise preparing or finishing it. There are two types of welding: heat or fusion welding, and pressure welding.

Hot work includes activities such as welding, cutting and grinding that produce hot metal, radiant heat and sparks. Hot work is typically well controlled within dedicated work areas such as workshops. However, maintenance and service work may need to be done in a variety of settings away from a workshop, which can introduce risk factors such as:. Without a spotter, the person undertaking the hot work may not notice spot fires, which can quickly escalate and may have serious consequences. Mineral exploration drilling - code of practice - K b.
