1.4 Uses & Limitations

The Amerex Modular Dry Chemical Fire Suppression System has two options for agent that can be used for suppressing and extinguishing fires:

ABC Dry Chemical - is a multipurpose ammonium phosphate based dry chemical which is effective in suppressing and extinguishing class A, B, and C fires. These fires can be involved in ordinary combustible materials, flammable liquids, and fires involving energized electrical equipment.

Purple K - is a potassium bicarbonate based dry chemical which is effective in suppressing and extinguishing class B and C fires involving flammable liquids and is safe on fires involving energized equipment.

CAUTION: Unless all sources of ignition have been removed, the system may be ineffective in suppression of flowing flammable liquid fires. Flammable gases present a potential explosion hazard. The flow of fuels and other combustibles must be stopped before or during activation of the fire suppression system.

Amerex Modular Dry Chemical Fire Suppression System shall not be considered satisfactory protection for the following:

Chemicals containing their own oxygen supply

Combustible metals such as sodium, potassium, magnesium, titanium, and zirconium

Deep seated or burrowing fires in ordinary combustibles where dry chemical cannot reach point of combustion

Explosions

Amerex Modular Dry Chemical Fire Suppression Systems are useful in protecting major vehicle components such as engines, transmissions, charging systems, hydraulic systems, and brake systems. These systems can also give equipment operators additional time to evacuate the vehicle in the event of a fire.

Part No. 13980 Rev. J, January 2015

Chapter 2: Component Description The following sections describe the various components available for use with the Amerex Modular Dry Chemical System. These include Agent Cylinders of various size and capacity and the Cylinder Brackets used for mounting each Agent Cylinder. Also included are the components that comprise the Agent Distribution Network, the Nozzles used for dispersing the Dry Chemical Agent, and various control heads and accessories used to actuate and discharge the Agent Cylinders.

2.1 Agent Cylinders

The Amerex Modular Dry Chemical System Agent Cylinders are available in multiple sizes, with different mounting options and orientations. The Agent Cylinders are shipped fully charged from the factory. Each Agent Cylinder includes a brass Agent Cylinder Valve with a Pressure Gauge and a safety Rupture Disc with Dust Cap installed. Agent Cylinders are pressurized with nitrogen gas to a pressure of 350 psi (2413 kPa) at 70°F (21°C). V13 through VSR75 Agent Cylinders are equipped with a Shipping Plate (P/N 10099) on top of the Agent Cylinder Valve and Anti-Recoil Plate (P/N 10646) installed on the Agent Cylinder Valve discharge outlet to prevent accidental discharge and to minimize recoil in the unlikely event of an accidental discharge during shipment. (See Figure 2.1.a). V150 and V250 Agent Cylinders are equipped with a Protective Cap (P/N 17990) and Anti-Recoil Plug (P/N 17559) to prevent accidental discharge and to minimize recoil for an accidental discharge during shipment (See Figure 2.1.b). These safety components are removed only when the Agent Cylinder is installed in the Cylinder Bracket and connected to Agent Distribution Network.

WARNING: PLATES (FIGURE 2.1.a) AND PROTECTIVE CAP AND ANTI RECOIL PLUG (FIGURE 2.1.b) WILL BE REMOVED AT INSTALLATION AND RETAINED FOR LATER

USE. DO NOT REMOVE UNTIL DIRECTED TO DO SO.

Agent Cylinders are DOT 4BW350, tested to 700 psi (4826 kPa) and require a hydrostatic test every twelve years, or more frequent intervals if warranted. The operating temperature range of the Agent Cylinders is -65°F to 150°F (-54°C to 66°C).

Chapter 3: Hazard Analysis

3.1 Introduction

When performing a hazard analysis, some helpful tools that can be useful are:

Flashlights – for those hard to see places.

Cameras and note pads – for helping with documenting the construction of the vehicle fire suppression system and creating a bill of materials. Installers must document and retain all system designs.

Temperature measuring devices – Thermocouples work well in helping to identify vehicle operating temperatures. Knowing the vehicle operating temperature details is crucial in selecting appropriate hardware when doing a hazard analysis and system layout.

Access to all Amerex Installation, Operation, & Maintenance Literature – System may require hardware not located in this manual.

NOTE: On all installations, consult the vehicle manufacturer and property owner before making any modifications to equipment.

3.2 Hazard Analysis

A hazard analysis is used as the first step in a process used to assess risk of fire. The result of a hazard analysis is the identification of fire risks. The National Fire Protection Association (NFPA) offers a series of standards with guidelines for a particular product or system being installed. When conducting a hazard analysis, all applicable standards must be observed.

Examples of such standards include, but are limited to: NFPA 17, 17A, 52, 120, and 122.

Below are some additional considerations to be evaluated when doing a hazard analysis.

3.2.1 Identify the Ignition Source(s)

The potential for hot surfaces such as exhaust manifolds, muffler compartments, hydraulic pumps, and turbochargers can be ignition sources. Other hot surface ignition sources can be friction buildup from bearings, brakes, and gears. Electrical shorts from vehicle electronics and batteries can also be ignition sources.

3.2.2 Identify the Fuel Source(s)

Fuels can be found in many different forms including, but not limited to:

Class A Material - Wood, paper, coal dust, rags, hoses, tires, combustible refuse buildup.

Class B Material - Flammable and combustible liquids such as gasoline, diesel fuel, cleaning fluids, hydraulic fluids, brake fluids, transmission fluids.

Class C Material - Class C items describe sources of electrical current that can energize an area where a fire is present.

3.2.3 Consulting Vehicle Owner and/or Original Equipment Manufacturer

Previous experience with machinery may indicate where special hazards exist.

Knowing the history about a particular model of vehicle/machine may help with decisions in protection.

3.2.4 Potential Workplace Hazards for the Equipment

Refuse vehicles frequently work in landfills. Some landfills carry substantial class A fuel sources. Machines working in steel refineries can be exposed to external ignition sources. These types of external hazards will have to be considered when determining the right protection required for the particular machine.

Part No. 13980 Rev. J, January 2015

3.2.5 Considerations to be Evaluated

Is the hazard in an open area or closed compartment? In an open area, each hazard must be treated as a local application with direct aim of Nozzles. Open area hazards are more difficult to contain, and will require a more conservative approach for selecting agent and Nozzle quantities. Closed compartments can aid in keeping Dry Chemical Agent in the hazard area longer allowing for better coverage.

Are there many obstructions? Although dry chemical can act as a total flooding agent in enclosed hazard areas, obstructions can limit the force of the agent discharge for direct application on a fire. Direct application of agent is a very effective way to extinguish many fires. It may be necessary to use additional Nozzles to compensate for obstructions.

How much air flows through the hazard? Airflow can adversely affect aim of nozzles and dispersion of Dry Chemical Agents. It may be necessary to use additional Nozzles to compensate for air flow.

What are the dimensions of the hazard? Determining hazard dimensions allows for Agent Cylinder size(s) and Nozzle quantities to be calculated.

What is the potential for the hazard to spread to other areas of the vehicle/ machine? Additional protection may be required for those areas as well.

Does the vehicle/machine have additional hand portable extinguishers? Hand portable fire extinguishers are necessary to be used as a backup to an automatic fire suppression system. Appropriate type and rating of hand portable fire extinguishers must be considered.

3.2.6 Selecting the Appropriate Agent

After identifying ignition and fuel sources (see Sections 3.2.1 and 3.2.2), the appropriate fire suppression agent must be selected.

ABC Dry Chemical - Works well on all Class A, B, and C fires.

Purple K Dry Chemical - Works well on Class B fires.

ICE Liquid Agent - Works well on Class A and B fires and is good for cooling hot surfaces (turbochargers, exhaust manifolds), but must not be used on electrically energized equipment (batteries, alternators, starters). See the latest version of the ICE System Manual (P/N 22012) located on the Amerex website at www.amerex-fire.com.

3.2.7 Selecting the Appropriate Method of Detection

After identifying vehicle hazard areas, it is necessary to select the appropriate form of detection for those areas. See the applicable electronics manual located on the Amerex website at www.amerex-fire.com.

Spot Heat Detectors - Localized area devices that react to “set point” temperatures of 280ºF (138ºC), 350ºF (177ºC) or 450ºF (232ºC).

Programmable Heat Detectors - Localized area devices that react to “set point” temperatures and can be effectively programmed to a temperature between 140ºF (60ºC) and 550ºF (288ºC) with rapid response to heat.

Linear Heat Detectors - Broad area “linear wire” devices of various lengths, that have large surface area for heat detection with a “set point” of 356ºF (180ºC).

Optical Flame Detectors - Rapid response devices that react to a visual flame signature. These must have visible line of sight to flame to be effective.

3.2.8 Selecting Methods of Actuation

If automatic actuation of any Agent Cylinders in the Amerex Modular Dry Chemical Vehicle Fire Suppression System is selected, a manual means of actuation is also required. At least one manual means of actuation must be located within reach of the vehicle operator during normal vehicle operation. Additional manual means of actuation should be located conveniently in accessible areas along paths of egress.

Such manual actuation devices include:

Manual Actuation Button - An electronic button located in the drivers area or other locations accessible in the event of a fire. This button is used in conjunction with the Amerex Modular Electronics System. See the applicable electronics manual located on the Amerex website at www.amerex-fire.com.

Manual or Manual/Electric Actuator (P/N 10210 or 23600) - Pneumatic actuation device located in the drivers area or other locations accessible in the event of a fire (See Section 2.5.4 or 2.5.5).

Chapter 4: System Design & Installation This Chapter describes system design and installation of the Amerex Modular Dry Chemical System. The addition of electronics, detection, additional agent selection, and any other components required to complete the Amerex Fire Suppression System can be found in technical literature section of the Amerex website at www.amerex-fire.com.

4.1 Steps to System Design

The appropriate selection of fire suppression agent(s) should be made after a hazard analysis has been completed.

After selecting the ideal fire suppression agent(s), the designer must identify the associated Nozzle types and Nozzle quantities that work with the particular fire suppression agent(s) selected (See Section 4.2)

Nozzle locations must be selected and Nozzles installed (See Section 4.3).

Agent Cylinder(s) must be located and installed to support Nozzle location and selection.

Limitations and requirements (See Section 4.4) should be followed as well as Agent Distribution Network limitations (See Section 4.5).

Agent Distribution Network(s) must be constructed and installed (See Section 4.5).

System actuation methods and control heads must be selected (See Section 4.6). Fire detection methods and the appropriate Amerex Modular Electronics System must be selected and considered when choosing system actuation methods. See the applicable electronics manual located on the Amerex website at www.amerex-fire.com.

If Pneumatic actuation is chosen, Nitrogen Cylinders and the desired actuator must be located and installed to support Agent Cylinder location and control head selection.

Location and mounting limitations and requirements should be followed as well as Pneumatic Actuation Network limitations…
