Would you consider an electric hob to be an heat source as it is not a naked flame. All guidance ignores electric fires. Could the heat ignite the oxygen?

Oxygen is non flammable but supports combustion. Having said that it makes sense to keep oxygen cylinders away from anything that could create a fire. Just google for a MSDS.

As DNW said, the oxygen cannot ignite, the problem with heat is that it can cause overpressurisation.

SBH,
With respect and as usual this may well offend, but if you have to ask this question, are you sure you are the right person to carry out a FRA or to interpret the results of same?

To be fair, SBH hasn't mentioned FRA and may not be either doing or interpreting one, but could just be interested in how oxygen cylinders ought to be stored.

Click on the link SBH, should have all h info you need. As Kate said if the pressure release valves fail then rupture/explosion is a possibility and if they work as they should then the released oxygen exacerbates the fire. So basically keep them away from both heat sources and combustible materials.
