Compact Fire Suppression System The Top 4 Applications ELECTRICAL CIRCUITRY Electrical cabinets Control boxes Recharging stations Switch panels Relay stations MACHINERY CNC Machines Construction machinery Agricultural machines Construction equipment Forklifts OILS, CHEMICALS AND OPEN FLAME Fume Cabinets Paint & Chemical storage Petroleum storage tanks Hydraulic circuits VEHICLE ENGINES: Buses & Trucks Trains & Trams Farm Equipment Military Vehicles

ELECTRICAL CABINETS Why protect Electrical Cabinets? 65% of all large-loss fires start as electrical fires (NFPA). The #1 cause of fire. Consequences: Damage to equipment and surrounding areas Operations interruption/downtime Financial Loss Possible loss of clients A fire not quickly detected can not only destroy an electrical cabinet, but also surrounding equipment. If the sprinkler system actuates, the cost and downtime can be extensive.

ELECTRICAL CABINETS Causes of Fire Short-circuits, overloading ou overheating of components Defective electrical connections. Electrical malfunction Electrical surges. Formation of intermittent arcs. Fatigue of electrical wires Poor installation. Faulty equipment

ELECTRICAL CABINETS Pre-engineered for: Electrical Cabinets Computer installations Electronic Equipment Control Boxes Battery recharging stations Inversion panels Relay switches Control centers Main switch boxes Cable rooms Cable ducts Emergency supply panels Transformers High voltage equipment

CNC MACHINES Why protect CNC Machines? An estimated 15% of machine shops experience a machine fire every year. The average cost of a CNC machine is over €70 000. Consequences: Destruction de l’équipement. Interruption of production/downtime Significant Financial loss – replacement and cleanup Potential late orders and loss of client If the sprinkler system were to actuate, it can often cause more damage than the fire itself.

CNC MACHINES Causes of Fire Combustion of oil residues and flammable metals A malfunction of the coolant system. Tool breakage Hot metal chips. Static electricity due to friction. Poor maintenance. High friction. Operator error.

CNC MACHINES Applications Automated Machines (CNC) EDM Machines Dust Collectors Grinders Woodworking Equipment Construction Equipment Agricultural Equipment Elevators & Escalators Almost any machine

LABORATORY FUME HOODS Why protect Fume Hoods? Fume cabinet fires are a major safety issue in laboratories High risk situation where chemical vapors combine with open flame (bunsen burner) Consequences: Technican injury Loss of specimen Destruction of equipment and surrounding lab area Lab downtime Financial loss

LABORATORY FUME HOODS Causes of Fire Focus Areas: Ignition of chemical residues and vapors in the extractor Open flame (bunsen burner) Heating plates Volatile and reactive agents Technician error Focus Areas: Fume Hoods Chemical or Paint storage areas Petroleum storage Hydraulics All zones at risk for chemical combustion

SYSTEM DESIGN: KEY CONSIDERATIONS 1 Type of Fire Hazard Calculation Method: 2 Suppression Agent 3 Enclosure Geometry 4 Limits 5 Calculate System Size 6 Additional Functions

SYSTEM DESIGN: Type of Fire Hazard

SYSTEM DESIGN: SUPPRESSION AGENTS HFC 227 ea Liquid at ambient temperature Ideal for sensitive equipment US EPA SNAP approved No post-fire residue or cleanup Electronically non-conductive 0% ODP Good environmental profile

SYSTEM DESIGN: Enclosure Geometry Area = L x W Volume = L x W x H Length Height width Area = L x W Volume = L x W x H Adjust for the volume of non-burnable objects Use only the raw enclosure volume

SYSTEM DESIGN: Enclosure Geometry Geometry will determine number of nozzles to use. Use 1 nozzle for most systems – place in center. Consider using 2 nozzles for long or oddly shaped enclosures. Objective: Achieve 95% design concentration within 10 seconds.

SYSTEM DESIGN: Limits Respect the limits: Maximum coverage area Maximum pipe length

SYSTEM DESIGN: SYSTEM SIZE Example: Protect a 4’ x 4’ x 6’ electrical cabinet with HFC 227 ea 1 Design Concentration What is the fire hazard? Class C Electrical What is the extinguishing agent? HFC 227 ea Use Table 1 to look up the design concentration: 7.5 2 Flooding Factors Round up design concentration to a whole number: 8 What is the minumum temperature? 60° F Use Table 2 to look up the flooding factor: 0.0402 3 System Size Calculate the area: Length x width x height: 96 ft.3 Multiply the area by the flooding factor: 4.032 lbs The 7 lb.
