What kind of info do you want to see? I'm working with a publishing group to make self paced
sign industry courses based on defined standards. Would something like that be interesting?
There are national standards for school buses in the federal laws, even defining "national school bus yellow" as a color only for school buses.
For fire those specs will be issued by the agency, be it federal state or local. Every firetruck is custom built to the specs defined by the purchaser. Each apparatus lasts 20 years tho. So it's a one time sale.
There are NIOSH and OSHA rules that intersect with those specs and are usually Incorporated by mention. Of particular interest is the workplace safety sections for emergency vehicle operations and the emergency scene signage now required to be displayed. Good money there
As for cops, theyre wide open as their fleet graphics design (livery) is a prominent point of pride for the folks in blue. Literally sell this by contacting the fleet manager or chief of every Dept your willing to serve.
A growing sector of high-end livery work is towing and recovery. They are becoming more aware of the risks from idiot drivers, and are keen to use the diamond grade films for maximum visibility. This is a challenging product to work with, is expensive, and needs some special equipment, but the results are several thousand $ on graphics per tow truck, and an insurance savings for them. Look at their fleet, roadside assistance trucks also need that visibility.
I'd suggest you study 3Ms website for reflective films for detailed instructions, as well as oracals website. Avery isn't much of a player in the reflective films market any more.
Pricing is premium, I often get in excess of $30 PSF. There's no reason to sell this stuff cheap.
As for great standards.. look to our friends over the pond, where the markings have standards based on visual science. They may seem ugly but they are most visible. Emergency vehicles here are caught in a time warp.
its only a freaking
sign!
