Fire Code matters
Suppression Systems
Suppression allegations frequently follow a closed valve, an impaired system during construction, or a commercial kitchen hood that was cleaned but never serviced. Because these systems are relied on to control a fire before crews arrive, enforcement is firm and prosecutors expect proof of restoration.

What the Code expects
- Sprinkler and standpipe systems kept in service, with valves open and supervised.
- Commercial cooking equipment protected by a serviced suppression system.
- Impairments managed, recorded, and ended as soon as work permits.
- Periodic inspection and testing carried out and documented.
What is typically alleged
- Leaving a control valve closed or a system otherwise impaired.
- Failing to maintain a kitchen suppression system or its nozzles and links.
- Obstructed sprinkler heads from storage, shelving, or new partitions.
- No records of required periodic inspection and testing.
Evidence that matters
- Impairment logs, tags, and contractor reports for the period alleged.
- Photographs of valve positions, storage clearances, and nozzle coverage.
- Timeline of construction or repair work affecting the system.
- Grease-cleaning and suppression-service records for kitchen matters.
Possible outcomes
- Withdrawal once restoration and testing are verified in writing.
- Negotiated resolution recognizing an impairment that was properly managed.
- Reduced penalty where a contractor, not the owner, created the condition.
- Defence where the system was in service at the material time.

Suppression Systems — common questions
- A sprinkler head was painted by a trade. Is that an offence?
- Painted or obstructed heads are commonly alleged because they affect activation. Trade contracts, site photographs, and remediation records help show who caused the condition and how quickly it was corrected.
- How often does a standpipe or sprinkler system need testing?
- Testing intervals depend on the system type and referenced standard, and monthly, annual, and multi-year requirements can all apply. A current inspection, testing, and maintenance log is the practical answer.
- Is a shut valve during repairs a violation?
- Systems taken out of service usually require notice, interim measures, and prompt restoration. Documenting the notification and the fire watch is often what separates a defensible outage from a charge.
