2.4 All the personnel in and around the working area including an operator should wear
appropriate protection to protect themselves from fumes and gases produced by
welding.
●DO NOT inhale fumes and gases generated by welding.
WARNING
●Ventilate the area sufficiently and wear a welder’s shield mask if
necessary.
●Fumes and gases generated by welding have a harmful effect on
human body.
●Welding in a small area may cause suffocation due to the lack of
air.
1) KEEP YOUR HEAD out of fumes and DO NOT inhale any.
2) USE FORCED EXHAUST VENTILATION at the arc.
3) VENTILATE the area to prevent build-up of fumes and gases.
4) If ventilation is insufficient, USE APPROVED BREATHING DEVICES.
5) READ AND FOLLOW WARNING LABELS on all containers of welding materials.
6) Before use, READ AND UNDERSTAND the manufacture's instructions, Material Safety Data
Sheets (MSDSs), and follow your employer's safety practices.
7) To prevent gas poisoning and suffocation, use a local ventilator or a respirator specified by
your country’s domestic laws.
8) Be sure to ventilate the area or wear a respirator by welding in a small place. A well-trained
watchman should observe the work.
9) Do not weld near the place where degreasing, cleaning or spraying is carried out. The heat
and rays of the arc can react with vapors to form highly toxic and irritating gases. If welding is
carried out there, harmful gases may be produced.
10) Toxic fumes and gases are produced when coated steel is welded. Be sure to ventilate the
area sufficiently or use a respirator.
