This seems like a simple question, but it’s interesting how often we are asked.
Legibility and Durability
There are no recommendations regarding the colour of the pen to be used when completing WPTW documentation.
The only consideration should be that the information is legible and clearly communicates the conditions of the Permit and the required controls. Darker colours such as black and dark blue will obviously reproduce more clearly, particularly if there is a need to photocopy documentation.
Pencil? Maybe not.
We would suggest that pencil is probably not durable enough for wellsite work environments and should be avoided.
