Oxygen Generators

[AM]

A question has come up on a risk assessment on a healthcare premises. The occupants of this building use oxygen generating machines to assist breathing, that filter the air and increase the o2 levels. If these machines, for whatever reason are left unattended, and the furniture which the mask is left on absorbs higher levels of o2, will there be any effect on the fire retardancy of the materials? Has any research been carried out on this?

Interesting question.  Can furniture absorb O2 in a room or will it be that the room itelf has just got a higher than normal O" content?

Sorry for the very simplistic approach, but can’t you have a sign saying

'Turn off when not in use’

have a look at the following link near to the end the are pictures of clothing enriched with O2

Not come across these would be interested in more information or manufacturer name.

The flammability of all combustible materials in an oxygen enriched atmosphere must be greater than normal. The ignition temperatures will also be reduced.  (See report on HMS Glasgow fire on the Tyne).

This situation can occur even if oxygen in cylinders is used.
Current advice is to clearly indicate and warn of the dangers and to turn off when not in use.

The HSE produce a booklet on this.
