ISO Engine Company Equipment
Below a list of the equipment ISO looks for on an engine. We have combined the list with equipment ISO will accept in lieu of the primary list. Normally this would be two separate schedules and would require cross-checking from one sheet to another. Hopefully, this combined list will save you a little trouble when you are preparing to upgrade your ISO rating. Please be advised that this list is not in any way to be considered official. To get the actual ISO documents you can follow these links.
The official ISO website is
here.
The official list of equipment ISO expects to see on an
engine is here.
The official equivalence list is
here.
Many of our customers complain that some of the items on the list are either arbitrary or would simply sit in a compartment only to be used for ISO inspections. That is why we have combined these two lists in one handy place. This way if you don't really need what they are looking for you can easily find what they will accept that you might actually use.
Some items can earn partial credit if you do not have the specified amount. For example, ISO will award 64 points for air packs if you have the required four units on your apparatus. If you have less they will award 16 points for each one on the unit. The official list gets into more detail on the points aspect of grading.
Items listed as spare may also be carried on the apparatus.
We hope you will find this list useful.

Note 1 - For some reason supply hose is not on the ISO points list except as an aside which reads, "The fire apparatus should also have supply hose and firefighting hose. For maximum credit, the engine company should carry 1,200 feet of hose. This can be 1,200 feet of 2-1/2" or larger supply hose or a combination of 2", 2-1/2", or 3" hose (up to 400 feet) and 2-1/2" or larger hose (up to 800 feet)." It is confusing but that is how they have it in their printed material. In the equivalency List it is stated that, "The first 400 feet can be 2", 2-1/2" or 3"; the remaining 800 feet must be 2-1/2" or larger hose.
Note 2 - If your Basic Fire Flow is calculated to be less than 1500 GPM, the master stream appliance is not needed. Here is the document that can be used to calculate your Basic Fire Flow.
