HFC-227ea Fire Extinguishing System

The EuroSafe Fire Systems ES Series Clean Agent Fire Extinguishing System utilizes HFC-227ea as the extinguishing medium. HFC-227ea is a colorless, non-toxic gas perfectly suited to protect high value assets in areas that may be normally occupied, in locations where clean up of other agents is problematic, when storage space for a fire suppression agent is restricted, or when an electrically non-conductive agent is required. Each system consists of the following components and their associated accessories:

HFC-227ea Storage Components – Storage components consist of the cylinder assembly (s), which contains the HFC-227ea chemical agent, and the cylinder bracket(s), which holds the cylinder assembly securely in place.

HFC-227ea Distribution Components – Distribution components consist of the discharge nozzles used to introduce the HFC-227ea agent into a protected hazard along with the associated piping system used to connect the nozzles to the cylinder assembly.

Trim Components – Trim components complete the installation of the HFC-227ea system and consist of connection fittings, pressure gauge, lowpressure supervisory switch, electric valve actuator, and manual valve actuator

Slave Arrangement Components – Slave arrangement components consist of the pneumatic valve actuator(s), actuation check valve, bleed valve, pilot hose, and fittings required for a multiple cylinder (slave) arrangement.manual valve actuator.

Supplemental Components – Supplemental components include the discharge pressure switch and manifold check valve. They supplement the core equipment or complete a specific multicylinder configuration.

Control Panel – This device monitors the condition of the electric actuator, detectors, warning devices, cylinder pressure, and any manual release and abort stations. All electric or electronic devices must connect to the control panel in order to function.

HFC-227ea

CHEMICAL PROPERTIES

HFC-227ea is formed from the elements carbon, fluorine and hydrogen (CF3CHFCF3 – heptafluoropropane). The primary extinguishing mechanism of HFC-227ea is heat absorption, with a secondary chemical contribution from the thermal decomposition of HFC- 227ea in the flame.

HFC-227ea leaves no residue and is safe for use in occupied spaces. Most common metals, such as aluminum, brass, steel, cast iron, lead, stainless steel, and copper, as well as rubber, plastic, and electronic components, are unaffected when exposed to HFC-227ea.

System

CONSIDERATIONS

Although the EPA Significant New Alternative Program (SNAP) lists HFC-227ea as acceptable for occupied spaces, NFPAStandard 2001 and SNAP list the following guidelines for human exposure;

The discharge of HFC-227ea into a hazard may reduce visibility for a brief period. HFC- 227ea may cause frostbite if liquid discharge or escaping vapor contacts the skin.

When HFC-227ea is exposed to temperatures greater than 1300 ° F (700° C), the by product Hydrogen Fluoride (HF) will be formed. HFC-227ea systems are designed to discharge in 10 seconds or Less in order to minimize the amount of HF formed.

The HFC-227ea Material Safety Data Sheet (MSDS) should be read and understood prior to working with the agent.

A cylinder containing HFC-227ea should be handled carefully. The anti-recoil safety device must be in place at all times when the cylinder is not connected to the discharge piping and restrained.
