There's a jurisdiction that is considering requiring "Fire Fighter Air Replenishment System" or as I understand it a standpipe-for-air system. Has anyone designed these systems?

The International Fire Code (Appendix L) provides requirements for the system - my only concern is the size and storage of pressurized oxygen tanks either in or near the stairwells and the potentially increased hazard they could be in a fire.

Many fire pump arrangements I've seen include flanged fittings and pipe connections on the suction side of the fire pump. Is there a requirement for this?

Are grooved connections allowed for pipes and fittings on the suction side of the pump assembly?

My company has recently re-evaluated how we take measurements onsite in the hope that we can find better/faster solutions than running tape measures to nearby structure. We create shop/installation drawings, to precision in measuring parts of existing systems is important.

What do you use when on job sites? Tape? Laser Measure? 360 cameras? Has anyone had any luck using laser scanners or photometrics for measurements?

A fire marshal is requesting a wall hydrant on the backside of a project where there is limited access. Is there a prescriptive flow that needs to be calculated at this location?

This project is considered a high-rise (8 stories) and does have a fire pump. He has already requested there be 100 psi available at the wall hydrant.

A big thank you to those who chimed in during this past month - thanks for making this a more positive and helpful community!

​Top Contributors for October: 

We're looking into some basic-level risk assessment for an owner, and I'm seeking any data concerning the actual frequency that fires occur for different types of facilities. For instance - in a 12,000 sqft office building, how likely would a fire be to occur in a year? 

Where is a good starting point for gathering this type of information?
