A Fire Department Connection Cheatsheet

There’s no real way around it: I love cheatsheets.

In a design course in college we received 5x7 index cards to include any handwritten notes we wanted for an upcoming final. I wrote so much on that card with handwriting that was effectively size-4 font that it could have been displayed as a work of art. 

Nearly an entire semester summarized to a 5x7 card. It was a thing of beauty. 

While I no longer have a need to write so small, I still enjoy having information organized so that it is extremely easy to access. 

If you haven’t seen these before, here are a couple cheatsheets I’ve created so far:

​Last week I covered important considerations surrounding fire department connections from a design perspective, which was a joint-effort with QRFS covering the topic.

At some point I’ll compile the best blog posts and resources into a hardcover reference book. For this week, however, here’s a cheatsheet on requirements surrounding fire department connections across NFPA 13R, NFPA 13, and NFPA 14:
