Question

Ventilation requirements in arc and gas welding are established on the basis of several factors that govern the amount of contamination to which welders may be exposed. These factors include: ______________________________

Answer 1

Factors that determine ventilation requirements in arc and gas welding include the thermal energy produced by the electric arc, the release of pollutants, and the importance of proper ventilation and manufacturers' instructions.

Step-by-step explanation:

Ventilation requirements in arc and gas welding are established on the basis of several factors that govern the amount of contamination to which welders may be exposed. These factors include:

• The thermal energy produced by the electric arc in welding, which can melt the rod, spray sparks, and emit high-energy electromagnetic radiation
• The release of pollutants from combustion processes, such as carbon monoxide, ground-level ozone, nitrogen dioxide, sulfur dioxide, lead, and particulate matter
• The importance of maintaining proper ventilation and following manufacturers' instructions to minimize exposure to pollutants
