Special Hazard Fire Suppression

  • DESIGN
  • INSTALLATION
  • INSPECTION
  • LONG-TERM SUPPORT

Some environments require more than a traditional sprinkler system. When the hazard, equipment, or operational risk demands a different approach, special hazard suppression provides a more tailored solution.

WHAT LEE SUPPORTS

A defined scope across specialty suppression.

Lee provides support across a wide range of special hazard fire suppression systems — from inspecting and servicing existing installations to in-house design of clean agent systems.

Inspection & Service of Existing Systems

Inspect and service a broad range of installed systems so you can maintain performance, stay aligned with inspection requirements, and address deficiencies as they arise:

  • Clean agent systems
  • CO2 systems
  • Dry chemical & foam systems
  • Water mist systems
  • Releasing panels & associated controls
Group 76

Design & Installation of Clean Agent Systems

Lee performs in-house design and installation for clean agent systems — including system design, coordination, installation, and ongoing service:

  • FM-200
  • Novec 1230
  • Ecaro 25

Commonly used where water isn’t appropriate — data & server rooms, electrical equipment spaces, and critical control environments.

INSTALLATION SUPPORT

Specialty systems, executed and supported.

For more complex or specialized suppression systems, Lee provides installation execution, project coordination, system integration, and ongoing inspection and service. In these cases, system design and material procurement may be completed through a specialty partner — while Lee remains responsible for installation and long-term support.

  • FOAM SYSTEMS
  • HIGH & LOW PRESSURE CO2
  • WATER MIST SYSTEMS
  • INERGEN & INERT GAS
  • DRY CHEMICAL SYSTEMS

SYSTEM INTEGRATION & CONTROLS

Suppression is only part of the response.

Special hazard systems rely on more than suppression hardware. Proper integration ensures systems activate correctly and function as part of a complete life safety response. Lee coordinates across:

  1. Releasing panels: control of system actuation
  2. Detection systems: early, reliable initiation
  3. Fire alarm integration: a coordinated building response
  4. Shutdown sequences & control logic: safe, correct operation

WHERE THESE SYSTEMS ARE APPLIED

Selected by hazard — not by building type.

Special hazard systems are typically used where water-based suppression isn’t appropriate, where equipment or assets need additional protection, or where the hazard is tied to a specific process or condition.

INSPECTION, DEFICIENCIES & FOLLOW-UP

Kept effective over time.

Like all fire protection systems, special hazard systems require ongoing inspection and service to remain effective. Lee supports the full cycle:

  • Routine inspection & testing
  • Ongoing service & maintenance
  • Recommended corrective actions
  • Identification of deficiencies
  • System condition evaluation

Already have a system but unsure of next steps?

Lee can review system condition, identify performance concerns, evaluate inspection findings, and plan upgrades or replacements.
