Stored pressure type extinguisher is pressurized with Nitrogen gas as propellant which behaves qualitatively like an ideal gas, and approximately follows the Ideal Gas Law:
Pressure in the Ideal Gas Law (PV = nRT) is related to volume of the bottle (V), amount of gas in the bottle (n) and temperature (T). Therefore, as the temperature increases, for the volume and amount of the gas remaining constant, the pressure exerted increases. Conversely, as the temperature decreases, the pressure exerted decreases.
As working temperature of the extinguisher is normally -20◦C to 60◦C, thus the pressure in the extinguisher will vary as the temperature changes within the range, and therefore the needle is moving within the green zone of the pressure gauge.
The easiest way to check is to simply place the extinguisher in a controlled environment (an air conditioned room) for 24 hours. If the pressure gauge returns to its normal position, then the pressure fluctuation was due to temperature. If the pressure reading continues to be either too high or too low, then there may be a need for maintenance on the extinguisher in question.
Another method for checking the pressure within an extinguisher is by using a gas test kit.
Vibration test is required in USCG requirement but not required in EN standard. Eversafe extinguisher is designed and tested to EN standard as per MED 96/98/EC requirement, and therefore it is not tested for vibration test.
Emptying the propellant gas (nitrogen) from the extinguisher is not required for yearly basic inspection. However, inspection on pressure gauge is needed as to give maximum assurance that an extinguisher will operates effectively and safely by:
a. Visual inspection on pressure gauge – ensure that the needle is inside the green zone.
b. Check that the pressure gauge is operating freely – using gauge test kit.
CAP 437 is a standard for Offshore Helicopter Landing Areas issued by Civil Aviation Authority of UK. The CAP 437 minimum requirements for powder type extinguisher are as follow:
Minimum total capacity should be 45kg delivered from 1 or 2 extinguishers at the discharge rate of 1.35kg/s to 2kg/s.
Declaration of Conformity is issued to indicate that the product is produced via approved manufacturing processes, inspections and testing and it is in conformity with applicable EU Directives and design standard.
As the product is produced in a batch where a number of identical products is produced at one time, thus the Declaration of Conformity is issued for the whole batch of product and the serial number indicated in the attachment to the Declaration of Conformity is in range to prevent any typo error in the serial number and reduce time for generating the Declaration of Conformity.
Shelf life of Eversafe spare ABC 40 dry chemical powder is 3 years on condition that it is stored at ambient temperature in original packing, and away from direct sunlight and moisture or water contamination.
EVERSAFE ABC dry chemical powder is monoammonium phosphate (MAP) and ammonium sulphate based extinguishants.
Caking of powder into lumps is caused by moisture absorption.
CO2 extinguisher stores carbon dioxide gas at extremely high pressure (56bar), where the gas is condensed into a liquid. The carbon dioxide in the extinguisher is in a liquid state and remains a liquid because of the pressure it is under, a pressure that it self-creates as it tries to turn into a gaseous state. Even if there were half of the amount of carbon dioxide in an extinguisher as there should be, it would still create the same amount of pressure in the cylinder. Thus, pressure does not tell you how much agent remains in the cylinder, and therefore CO2 fire extinguisher do not has pressure gauge which is pointless in the case. In such, the only way to assess if a CO2 fire extinguisher is empty or full is to weigh it.
When operate the fire extinguisher levers, the pressure is released; the CO2 pressure is reduced by the diffuser (horn) and expands back into a gas, shooting out a white cloud resembling snow, rapidly cooling the surrounding air and removing oxygen from the area surrounding the fire.
The discharge hose and horn assembly of 6.8kg CO2 type portable extinguisher is tested to the electric strength test at voltage value of 1500V for duration of 1 minute and thus safe for use on electrical equipment.
This is due to the capacity of ECO-15HH is not covered in the EN 3 standard, and the extinguisher is designed and type approved to MS 1179: 1990 standard.
Shelf life of Eversafe carbon dioxide cartridge is 10 years from the manufacturing date and it is subject to annual weight check to ensure retention of propellant.
EN 3-8 (2006) incl. AC (2007) standard is applicable for those extinguishers with max. allowable pressure equal to or lower than 30 bar. Max. allowable pressure of CO2 type extinguisher is higher than 30 bar and thus the said standard is not applicable for this type of extinguisher. Therefore, this standard is not stated in the EC Type Examination (Module B) Certificate for CO2 type portable fire extinguisher.
The maximum recharging interval of the foam charge as stated in the BS 5306-3:2009 can be applied to vessel carrying PANAMA flag as it is comply with the requirements of Merchant Marine Circular MMC-226 dated June 2011 issued by Panama Maritime Authority, and IMO resolution A.951 (23).
Hydrocarbon fuel fires are fires from burning of hydrocarbons which have a specific gravity of less than 1.0 and therefore float on water. Examples of hydrocarbon fuels are gasoline, diesel, jet propellant (JP4), heptane, kerosene and naphtha. Aqueous Film-Forming Foam (AFFF) is normally used for combating this fire.
Polar solvent fuel fires are fires from burning of polar solvent which is miscible, that is they will mix with water. Polar solvent fuels are usually destructive to foams designed for use on hydrocarbons. Specially formulated foams have been developed for use on polar solvents (AR foam). Examples of polar solvent fuels are ketones, esters, alcohol including ethyl-alcohol (ethanol), amine, methyl tertiary-butyl ether (MTBE) and acetone.
Shelf life of Eversafe spare Aqueous Film-Forming foam (AFFF) is 5 years on condition that it is stored at ambient temperature in original packing, and away from direct sunlight.
Eversafe AFFF foam concentrates contain no Perfluorooctane sulfonate (PFOS) or Perfluorooctanoic Acid (PFOA) ingredients.
