A- Fire prevention and fighting:
1- In the event that it is not possible to remove the object to be welded from the workplace, all flammable materials shall be removed to a distance of not less than 35 feet (11 meters) from the place of welding.
2- In the event that it is not possible to remove the object to be welded, and at the same time it is not possible to remove all inflammable materials from the place of welding, appropriate curtains or covers are used to isolate heat, sparks and welding products. Also, cover all inflammable materials by non-combustible materials and spray the floor under the welding site with water to extinguish flying sparks.
3- Providing appropriate fire fighting equipment near the welding site for immediate use in the event of fires (appropriate extinguishing devices, fire extinguishers.
Hose Reels, ......).
4- Appointment of a fire watch, whose main tasks are to monitor flying sparks and resulting from welding operations within a distance of 35 feet (11 meters), with the necessity not to leave the welding place until at least half an hour has passed since its completion.
5- The necessity to ensure that the welding place is free of flammable materials or flammable gases by making the necessary measurements by measuring the percentage of flammable gases in the work atmosphere.
6- Not to allow any welding or cutting work to be performed in used drums except after thoroughly cleaning them and making sure that they are completely free of flammable materials.
B - Personal protection for employees
1- The need to use appropriate eye and face protectors (welding glasses, welding face shield) with the use of lenses with a filter suitable for the type of welding and electrode size.
2- The use of heat-resistant gloves, cotton overalls with long sleeves and without pockets. Also, there should be no folds in the pants and covering the shoes. There are sleeves and special covers for arms and legs.
3- Use a suitable protective shoe and also a leather apron can be used.
C - sanitary protection and adequate ventilation
The ventilation of the welding site can be from natural or mechanical ventilation.
1- Natural ventilation shall be sufficient if the area designated for welding operations is not less than 10,000 square feet and the ceiling for that place is not less than 16 feet.
2- In the absence of the above condition and consequently insufficient natural ventilation of the welding site, mechanical ventilation is used, such as local ventilation near the welding process, as it draws the fumes generated from the welding processes very quickly to a special filter. Ventilators can also be used to change the air in the workplace up to 20 times an hour.
