I'm trying to find a list of NFPA approved fire and sprinkler inspection companies for each state in the United States. Any idea if there is a published list?
I am not aware of any national database. You'll probably have to research it by state. For instance, Maryland has a list of current licensed sprinkler contractors on the State Fire Marshal's website: Md. State F.M. Approved Contractors
NFPA does not approve companies
UL does have a program for fire alarm companies.
And not every state requires companies to carry state cert.
OHHH I am not an engineer, so you can discount my reply if you want
Retrieving data ...
