Ventilation in an enclosed space
In addition to normal ventilation requirements, ventilation in welded and cut enclosures is also required to prevent accumulation of combustible mixtures and oxygen enrichment in the atmosphere.
Air used
The quantity and quality of the air used for ventilation must ensure that the concentration of harmful substances in the enclosed space is below the specified value.
Compressed air supplied to the respirator or breathing apparatus must meet normal breathing requirements.
The compressed air tube of the respirator must be a dedicated line and must not be connected to other lines.
Oxygen, other gases or mixtures should not be used for ventilation other than air.
Forced ventilation, supplied air breathing equipment or other suitable means must be used when performing welding, cutting or related work in areas where there is a direct risk to life and health.
Ventilation duct
Pipes used for welding, cutting or related process local exhaust ventilation must be made of non-combustible materials. These pipes must be inspected periodically as needed to ensure their function is stable and there must be no flammable residues on the inside surface.
