|COMMISSIONING A FIREPRO SYSTEM|
|The requirements of a installation are documented in the applicable standard.
• General Installations AS-4487
• Mobile Plant installations AS-5062
• Marine Installations are regulated by AMSA and MED regulations.
|The exact processes for commissioning will be determined by the risk analysis and the design. In general you need to :
• Inspect the installation for all aspects of the design.
• Test wherever possible detection, alarm and activation.
• Document the process. Copies of all should be in the logbook
• Commissioning Checklists are available on our website to download
|What Happens||Upon actuation the solid aerosol-forming compound SBK will undergo a combustion reaction generating the fire extinguishing condensed aerosol. Visibility will be restricted in the area as the discharge is a white gas. The compounds released are non-toxic and do not reduce the oxygen in the area. If a person is inside the risk area GET LOW AND GO SLOW to exit the risk area.|
|Residue||Residue of particulate matter after discharge of FirePro Aerosol Generators is approximately 10-15% of the aerosol weight of the generator. Example – 100g FirePro Generator will leave 10-15g of dust like residue distributed around the risk area. Does not produce any corrosive halogen acid by-products in its reaction with the fire.|
|Cleanup||The residue is non-toxic and non-corrosive, it is very dry as a result of the aerosol process so will attract moisture if not removed. This build up of moisture could be a cause of corrosion over time. The chemical nature of the residues (potassium salts) is slightly alkaline PH is approx. 8. Cleanup of the area is best achieved with a damp cloth, broom or vacuum cleaner.|
|FIREPRO ACTIVATION – COMPARED TO OTHER AGENTS|
|CO2||CO2 extinguishes fire by reducing the concentration of oxygen in the air to the point where combustion stops. CO2 is 1.5 times heavier than air and therefore tends to settle in the lower areas of the plant. This can be life threatening due to the oxygen displacement. CO2 causes injury and death as it interferes with the functions of the central nervous system. Visibility during the discharge is restricted as the discharge comes out as snow, contact with skin can cause frostbite.|
|FM200||FM-200 works by physically cooling the fire at the molecular level. Stored in hi-pressure cylinders as a liquid, and discharged as a gas. At high temperature gives off HF, CO – highly toxic.|
|NOVEC 1230||Novec 1230 interferes with the combustion process, stopping a fire in its pre-combustion stage, it disrupts a fire by absorbing the heat. Thermal decomposition producing HF and COF2 – highly toxic.|
|INERT GAS – Inergen, IG55…||Inert Gases extinguishes fire by reducing the oxygen level in a room to below 15% (the point at which most combustibles will no longer burn). Health hazard due to the depleted oxygen.|
|The maintenance of all fire equipment is covered by AS 1851 or AS 5602. The fundamentals are that all equipment is inspected at least every 6 months, and that testing of the performance of the equipment is completed annually. The frequency of inspections depends on the specific hazards involved in the risk, and in high hazard environments it may be decided to shorten the inspection time to monthly or quarterly. Some inspection tasks may be handled by the customer or operators of the equipment. The specific tasks involved are:
|Inspection||FirePro® Aerosol Generators to ensure that they are free from dust and other debris. Periodic inspection of the metal container (see life) of the solid extinguishing agent must be carried out to check whether the material is intact or has been damaged by chemically aggressive materials or corrosion.
Mounting Brackets and Bolts – All the metal brackets and connecting bolts must be inspected and tightened as necessary.
|Expected Life||A – 3 years with inspection every three months for very aggressive chemical environments
B – 5 years with inspection every six months for aggressive chemical environments
C – 10 years with an inspection every year for commercial and industrial environments
D – 15 years with annual inspection for offices, shopping centers, air conditioned environments
|Maintenance for Electrical
|If the unit is installed with electric activation additional maintenance is required. Periodic testing of electrical activation must be carried out to check that the internal electrical circuit of the activator is intact. All the electrical wires and connections of the FirePro® units to the control panel or the switch must also be tested and checked.|
|Logbook||Update the logbook. The installation should be maintained by an accredited person and a logbook must be kept, recording all the relevant events concerning the installation.|
