[edit] Summary

Here we have firestopped through-penetrations. The job is not done yet though. If the beams are not treated with fireproofing, they will twist and contort, expand and collapse and thus tear holes into this fire-separation. This is why the building code mandates that through-penetrations in a firewall (construction) are configured such that their collapse will not adversely affect the integrity of the firewall. The picture demonstrates clearly that firestops must precede spray fireproofing. It also shows that mechanical, electrical and structural penetrants can share openings and should be tested together to ensure bounding.
