In this case, listed firestops are installed (regardless of whether they were put in properly or not) and then savagely, carelessly re-entered but not re-sealed at all or not re-sealed properly (as in bounded by a certification listing) . Why bother doing it right in the first place if improper re-entries are to be tolerated?

Re-entered, firestop, installed way outside of certification tolerances, not re-sealed.

This system is listed for openings much smaller, with penetrants much smaller than what is being shown here (and in this particular manufacturer's literature, sales manual and promotional video), in this BC pulp and paper mill. This is not a good start. Notice on the right hand side, that two massive power cables were routed through an oversized re-entry hole. No repair was performed.

Re-entered C1000 firestop seal in Pulp Mill, heavily fractured, not re-sealed.

This is one way to beat up a firestop. You are looking at a partial view of a firestop mortar seal. There is an unsealed re-entry with wiring at the bottom right hand side. On the other side of this seal, there are huge transformers. Transformer ruptures and fires are a bit of a menace to insurers (Big bucks!). This re-entry was done with such force, that the whole seal has delaminated from the top of the opening.

Simple solution?

Regular, knowledgeable maintenance. Education of site electricians.

Re-entered Firestop mortar, installed too thin (cheaper that way) and not re-sealed - all in a federal Gov't building.

Another firestop mortar seal - re-entered but not re-sealed. In this case, the re-entry revealed that the thickness of the mortar, which should have been 3" as per the listing, was less than 1" in spots. This is not the work of an amateur. The tooling of the seal is great. But he saved a lot of money in mortar.

Simple Solution?

Pre-tender, use the proper specification. Post tender: enforce it. Post commissioning: implement the right maintenance program.

Apart from a few bad apples, manufacturers typically furnish correct instructions with their products. But the baseline is listings, listings, listings. The installed configuration must be bounded by a certification listing - not just at the time of commissioning, but throughout the life of the building. With proper planning at the design stage, which excludes busting up the workscopes among all the trades, and a meticulous maintenance plan, (the two being finely tuned to one another) the examples shown here could not occur.

More non-compliant firestops, too thin to begin with, re-entered and not re-sealed.

More of the same but with a bigger hole. Although it can lead to deaths, through negligence, this is not considered a felony in Canada, but one might consider the human result of such cost cutting measures if there is a fire. The information is very public and very available. The plausible deniability is zero.
