1. Why is extinguisher needle moving within green zone of the pressure gauge?

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.

2. How to determine functionality 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.

3. Is Eversafe portable fire extinguisher tested for vibration test?

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.

4. What is the thickness of corrosion resistant coating on external surface of extinguisher?
Thickness of Epoxy Polyester powder coating on external surface of Eversafe extinguisher body is >60μm.
5. Is Eversafe extinguisher equipped with any protective devices against exceeding the allowable limits of pressure equipment?
All Eversafe extinguishers are fitted with safety accessories such as bursting disc and safety relief valve as devices for direct pressure limitation, and pressure monitoring indicator which enable adequate action to be taken to keep the pressure within allowable limits.
6. Why are class C and D fires not given a numerical rating like class A and B fires?
Class A and B extinguishers carry a numerical rating to indicate how large a fire an experienced person can put out with the extinguisher. Class C extinguishers have only a letter rating because there is no readily measurable quantity for Class C fires which are essentially Class A or B fires involving energized electrical equipment. Class D extinguishers likewise do not have a numerical rating.
7. How to justify whether an extinguisher can be class C fire rated?
If an extinguisher has gained a Class B or Class A and Class B fire rating, it can be conformed suitable for use on Class C fire as per BS EN 3 fire performance requirements. However, this is applied only to powder type extinguisher.
8. Do you empty the nitrogen from the stored pressured type extinguisher and fill it up again when doing the yearly inspection in order to ensure the extinguisher is pressurized?

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.

9. When you have checked the pressure gauge thru the small hole on the glass, do you need to take off the old glass and replace it with a new glass?
There is a self-adhesive transparent round plastic seal covering the small hole. You have to remove the seal before checking the gauge thru the hole and cover the hole back with the seal after checking. Thus, removing the glass is not required.
10. What is Class D fire and which type of extinguisher can suppress this fire?
Certain metals are flammable or combustible such as sodium, titanium, magnesium, potassium, uranium, lithium, plutonium, and calcium. Fires involving such are designated “Class D”. Class D fire is usually specific to manufacturing processes or commercial processes that handle flammable metal and processes involving them. Dry metal powder is used to extinguish these burning metals.
11. What is CAP 437 and what is its minimum requirement for powder type extinguisher?

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.

12. What is Declaration of Conformity?

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.

13. Why does total quantity of product that stated in Declaration of Conformity not tally with actual delivery quantity to customer?

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.

CO2 Type Extinguisher


  • 1. Why are CO2 fire extinguishers not having a pressure gauge and how would you know if the CO2 extinguisher is full charged or empty?
  • 2. How does carbon dioxide fire extinguisher work?
  • 3. Is the discharge hose and horn assembly of 6.8kg CO2 type portable extinguisher safe for used on electrical equipment?
  • 4. Why is ECO-15HH CO2 extinguisher not designed to EN 3 standard and what standard is that the extinguisher designed to?
  • 5. What is the shelf life of Eversafe carbon dioxide cartridge?
  • 6. Why is EN 3-8 (2006) incl. AC (2007) design standard not stated in Eversafe EC Type Examination (Module B) Certificate for CO2 type portable fire extinguisher?
1. Why are CO2 fire extinguishers not having a pressure gauge and how would you know if the CO2 extinguisher is full charged or empty?

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.

2. How does carbon dioxide fire extinguisher work?

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.

3. Is the discharge hose and horn assembly of 6.8kg CO2 type portable extinguisher safe for used on electrical equipment?

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.

4. Why is ECO-15HH CO2 extinguisher not designed to EN 3 standard and what standard is that the extinguisher designed to?

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.

5. What is the shelf life of Eversafe carbon dioxide cartridge?

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.

6. Why is EN 3-8 (2006) incl. AC (2007) design standard not stated in Eversafe EC Type Examination (Module B) Certificate for CO2 type portable fire extinguisher?

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.
