providing and maintaining a safe system of work including:
       * using fall prevention devices (for example, temporary work platforms and guard railing)
       * work positioning systems (for example, fire resistant/flame proof industrial rope access systems), or
       * fall arrest systems such as catch platforms.
In some cases, a combination of control measures may be necessary, for example, using safety harnesses while working from an elevating work platform.
Welding should not be carried out on ladders. There is a risk of injury from falls due to the limited visibility of the worker, instability when working on a ladder and risk of electrocution if an aluminium ladder is used in conjunction with electric welding. Ladders may also be damaged by welding.
Further guidance about working at heights is available in the Code of Practice: How to Prevent Falls at the Workplace.

Manual tasks
Regulation 60: A person conducting a business or undertaking must manage the risks to health and safety relating to  a musculoskeletal disorder associated with hazardous manual tasks.
Welding may result in back strain from lifting or pushing and muscle strain from working in awkward positions. Additional hazards may arise from the use of personal protective equipment that restricts movement, grip and mobility.
Ways of minimising the risk of musculoskeletal disorders include:
    * designing the layout of the work area and positioning the work piece in a way that allows workers to adopt a comfortable position, and
    * reducing the amount of force necessary to perform tasks, such as using rigging to lift heavy work pieces and using trolleys to transport cylinders.
Further guidance on how to manage the risks of hazardous manual tasks is available in the Code of Practice: Hazardous Manual Tasks.

4.             WELDING EQUIPMENT

4.1         Ventilation
Ventilation can remove heat from the environment and reduce exposure to fumes and other atmospheric contaminants in the work area.
There are three main types of ventilation:
    * local exhaust ventilation
    * forced dilution ventilation
    * natural dilution ventilation.
The choice of ventilation system should take into account:
    * the amount and type of fumes and contaminants produced
    * the proximity and location of the welding process relative to the ventilation system
    * the level of ventilation, natural or mechanical, both for the whole workplace and the
      welding area – this will also depend on screens and partitions which may restrict cross-flow at the work area
    * the proximity of the welder's breathing zone to the fume source.

Local exhaust ventilation
A local exhaust system may comprise the elements listed:
    * a hood which captures the contaminant close to its point of generation
    * a duct system to move contaminant away from the work area
    * an air cleaning system to
