Frequently asked questions
I install sprinkler systems and fire suppression systems — is that ATECO code 43.22.03?
Yes. The installation, repair, and maintenance of fire suppression systems is 43.22.03. There is one important distinction to keep in mind: fire detectors — systems that detect and signal a fire — fall under a different code, 43.21.01. This code suppresses fires; that one detects them.
What is the difference between a fire suppression system and a fire detection system?
They are two distinct codes, as the exclusions field makes clear. 43.22.03 covers suppression — sprinklers and hydrants; fire detectors and smoke detection systems fall under 43.21.01, within the electrical installations group. The key question is whether the system suppresses or alerts.
I maintain sprinkler fire suppression networks — does it all fall under 43.22.03?
Yes, as long as the activity is installing, repairing, and maintaining suppression systems. If you also connect those systems to a remote security monitoring service, that monitoring service is classified under 80.09.00. The installation side of fire suppression remains 43.22.03; general plumbing and sanitary systems fall under 43.22.05.
