Where visual inspection of internal surfaces of a 4
/
A portion of a system can be blocked, that part of the system should be fabricated as a complets unit s
and a visual inspection should be performed just before the access points are closed.
4.2.2 Openings and pipe ends should be sealed at all times except when they must be unsealed to carry out necessary operations.
Fitted and tack-velded joints (which will not be immediately sealed by welding) id be wrapped with polyethylene or other haloganated plastic film until the welds car be lated.. (Commitment 5545 and 5543) 4.2.3 Markings Keep markings to a minimum (i.e., use tage with a.
ties),
b.
When markings are necessary use markers which are low in halogen content and easy to remove (for example, use felt tip markers rather than (o) crayons).
