Question

how can you manage hazards associated with breathing in welding fumes?
select the best option.
holding your breath
wearing a medical mask
using adequate ventilation
taking breaks

Explanation:

Holding your breath is not a practical long - term solution. A medical mask may not filter out the specific harmful particles in welding fumes effectively. Taking breaks reduces exposure time but does not directly address the presence of fumes. Adequate ventilation is the most effective way as it removes the welding fumes from the breathing zone.

Answer:

Using adequate ventilation.
