  work. When carrying out welding work, always wear welding gloves, apron, glasses, cap
  and other clothes suited for welding work.
• When carrying out any operation with two or more workers, always agree on the
  operating procedure before starting. Always inform your fellow workers before starting
  any step of the operation. Before starting work, hang UNDER REPAIR signs on the
  controls in the operator’s compartment.
• Keep all tools in good condition and learn the correct way to use them. Decide a place in the repair workshop to keep tools and removed parts. Always keep the
  tools and parts in their correct places. Always keep the work area clean and make sure
  that there is no dirt or oil on the floor. Smoke only in the areas provided for smoking.
  Never smoke while working.
