Hi there Vince,
The above conversation has pretty much covered everything and is very good advice.
In addition to the above, I have found the ‘Photo Registry’ for all inspection and investigations a handy tool. We do not normally give this document to the clients/owners, we keep it more for our records. Although, in some cases on inspections, we have given it to the clients/owners. It has helped them understand what we are trying to have them achieve in gaining compliance with the fire code. With regards to investigations, it helps explain what you are looking at and when submitted to OFM investigators, insurance investigators, it has been well received.
Also, it can be admissible as evidence if one has to go to court.
As Darren said, just adding my pennies worth.
