CHECKPOINT ACCESS P 7
WHY?
Improper access to a surface to be painted makes it impossible for the executor
to achieve a proper result of the job and for the inspector to evaluate the
outcome.
The result will be insufficient surface preparation and/or insufficient filmformation
and extremely variable dry film thickness of the coating system leading to millscale
and rust residues, insufficient roughness of the substrate, pinholes in the paint
film in some places and solvent retention and sagging in others.
The final consequence will be early rusting and fouling, low chemical resistance
and poor aestetical appearance.
Proper access means a distance of approx. 30 cm ( 1 foot ) from the working
tool the substrate at any location of the construction.
CORRECTIVE ACTIONS:
Rearrange access to area affected to fulfill above requirement. Inspect treated
substrate and retreat areas not acceptable.
In case of excessive film thickness, saggings or severe pinholing remove affected
paint by grinding before repainting.
PREVENTIVE ACTIONS:
Rearrange access to fulfill above requirement to distance to substrate surface.
Extension poles for spraying may be used, but remember that the painter should
have full visual contact to all surfaces to be painted, i e only to be used on
smooth surfaces like ships hulls and oil tanks exterior.
HOW TO DETECT:
Visually.
It is strongly advised to form an impression of safety of
scaffolding and other types of access at the same time for
your own safety.
