How a chlorate based oxygen generator works
MilSpec MPOG description
- Chemical block responsible for the generation of the oxygen – simple, safe, reliable and economical O2 source
- Sealed in a stainless steel canister
- Packed in a further outer stainless steel canister to protect from contaminants
- Ignition source – phosphorus match
- Thermal degradation of the chlorate after initiation of the product produces breathable oxygen
- Shelf life – 10 years
- No external power required

MilSpec MPOG phosphorus match
- Based on chemistry associated with safety matches
- Very stable in storage
- Incompatible with sodium chlorate
– Exothermic reaction fuels the initial decomposition of sodium chlorate in the igniter zone of the chemical block - Packaged separately
– No risk of accidental initiation during transport or stowage
MilSpec MPOG supply storage
- MilSpec MPOG is transported in metal stillage
– One stillage contains 25 units oxygen generators - Keep in a dry storage area that is protected from extremes
- Keep separated from combustible materials
Make use of the engraved markings and stillage map
– Design and carry out a life cycle management program - It’s recommended that the “igniter matches” are not stored in the same lockers as canisters but do need to allow easy access when needed.
MilSpec MPOG environmental testing
- Shocked
- Vibrated
- Frozen
- Thawed
- Shot
- Drop test was performed from 39 feet
- The entrance and exit points can be seen above
- The candle was successfully initiated at the end of the test
Advantages of MilSpec MPOG
- Use a phosphorus match initiator mechanism that is both easy to use
- 10 year shelf life with no maintenance requirements
- Packed in a further outer stainless steel canister to protect from contaminants
- Have been shock and vibration tested to meet requirements of submarine environment
- Much safer compared to pressurised and liquid oxygen systems
- Give 370+ litre of breathable oxygen per litre of storage space
- Can be deployed in less than a minute
