Another take on this.
If you have ACM's in your DB's they will be ar flash limitation, probably for semi-enclosed fuses (rewirable), there are other locations, but that plus the door seals are the most common, again to limit the potential of any electrical energy leaving the DB.
Now if the door gasket is an ACM, then really, you cannot open the board without disturbing fibres.
Ergo, in the event of a fuse "blowing", you need full ACM precautions class H vacuum cleaners etc. to open the board and replace the fuse wire/fuse.
Think of the downtime…
Next if it is a fuse carrier, then you can’t remove that to re-wire a blown fuse without full ACM precautions, so I hope that you have no mission critical systems connected to the DB’s?
If you do then I strongly suggest you review how mission critical these are, and your plans to address any circuit failures.
Next, your EICR should have indicated “unsatisfactory”, therefore something needs to be done to bring the installation into compliance. Your business insurance may be void because of an “unsatisfactory” EICR.
The presence of ACM’s within the electrical installation has to be a C2, and a single C2 on an EICR results in the installation being unsatisfactory.
Why.
Here are the two relevant paragraphs from BS7671:
>>>
634 PERIODIC INSPECTION AND TESTING
634.1 Following the periodic inspection and testing described in Chapter 62, an Electrical Installation Condition Report, together with schedules of inspection and schedules of test results, shall be given by the person carrying out the inspection, or a person authorized to act on their behalf, to the person ordering the inspection. These schedules shall be based on the models given in Appendix 6. The schedule of test results shall record the results of the appropriate tests required of Chapter 61.
634.2 Any damage, deterioration, defects, dangerous conditions and non-compliance with the requirements of the Regulations, which may give rise to danger, together with any significant limitations of the inspection and testing, including their reasons, shall be recorded.

My bold.
So, is the presence of ACM’s a “dangerous condition”.
Does exposure to the ACM have the potential to kill?...
