Reliable Sprinkler System Services Mississauga for Your Facility

Mississauga’s massive concentration of industrial space — particularly the logistics hubs surrounding Pearson Airport — creates sprinkler design challenges driven by building scale and storage configurations. High-bay warehouses with ceiling heights exceeding 40 feet require Early Suppression Fast Response (ESFR) sprinkler systems to protect high-piled storage without relying on in-rack sprinklers. Cold storage facilities require specialized dry-pipe or double-interlock pre-action systems. Mississauga Fire and Emergency Services enforces NFPA 25 and Ontario Fire Code compliance across Peel Region. SESSI designs robust sprinkler solutions specifically engineered for Mississauga’s industrial sector.

Types of Sprinkler Systems We Install

Mississauga Fire and Emergency Services enforces NFPA 25 inspection standards for all commercial and industrial sprinkler systems in Peel Region. These are the required compliance intervals for your Mississauga facility.

Wet Pipe Systems — The most common type. Pipes are always filled with pressurized water, providing the fastest response.
Dry Pipe Systems — Pipes contain pressurized air or nitrogen. Water releases when a head activates. Ideal for unheated spaces.
Pre-Action Systems — Require both a detector activation and a sprinkler head to open before water flows. Used in data centres and museums.
Deluge Systems — All heads open simultaneously when activated. Used in high-hazard areas such as aircraft hangars and chemical storage.
Residential Systems — NFPA 13R and 13D compliant systems designed for dwelling units and low-rise residential buildings.
ESFR (Early Suppression Fast Response) — High-flow heads designed for high-rack storage warehouses.

Sprinkler System Services Mississauga — Frequently Asked Questions

Common questions about sprinkler system services Mississauga, inspections, and Ontario Fire Code requirements for Mississauga properties.

Early Suppression Fast Response (ESFR) sprinkler systems are designed to suppress a fire entirely, rather than just control it until the fire department arrives. They discharge a high volume of water rapidly. ESFR systems are common in Mississauga’s logistics sector because they allow for high-piled storage without the need for complex in-rack sprinkler networks.

Mississauga cold storage and freezer facilities require dry-pipe or pre-action sprinkler systems to prevent freezing. In some cases, double-interlock pre-action systems are used to prevent accidental water discharge into the freezer, which can cause catastrophic ice damage. SESSI designs and maintains these specialized cold-rated systems.

If you change the racking layout, commodity class, or storage height in a Mississauga warehouse, your existing sprinkler system may no longer provide adequate protection. Before altering storage configurations, SESSI conducts a hydraulic analysis to ensure the system still meets Ontario Fire Code and NFPA 13 requirements.

Mississauga Fire and Emergency Services inspects commercial properties to ensure sprinkler systems have current NFPA 25 inspection tags, control valves are open and monitored, and sprinkler heads have adequate clearance (typically 18 inches) below the deflector. SESSI ensures your system passes these audits effortlessly.
