My company have been worried over times on issues that concern acetylene gas and oxygen in a troller or a cart.
Fact is the high ratio of the imflammablity and compartibility could cause a high rate of explosion.
Can anyone please imform me if there are any new laws that required that both should be seperated from the troller?
I will appreciate the every information I receive.

Here in the UK Oxygen and Acetylene bottles when not in use have to be stored seperately in a suitable bottle cages. In this case the cages must be at least 3 metres (10 feet) apart and a similar distance away from any building.

Remember that there should be one bottle cage for Oxygen and another for Acetylene.

Also, the definition I have seen here for 'in use' basically means with regulators and flashback surpressors fitted. Take these off and the bottles are no longer in use.

I hope that helps.

Dear all,
I wish to being to notice that I am having some problems in understanding what Teflon Tapes on a gas bottle is all about.
Can anyone tell me all about it and what's and its uses.

Regards,
Stanley.

Ken C,

I beg to differ. The minimum separation distance between oxygen and acetylene bottles in storage is nil. I refer you to BCGA guidance note 2, Guidance for the storage of gas cylinders in the workplace.

Ken C,

Sorry, finger problems. The 3 metre rule is generally for LPG and other liquified flammables. It is also permissible to keep a spare cylinder of each type in the workplace. Similarly, your 3 metre rule for buildings is a bit of a generalisation.

As you all seem to know what you are talking about thought I would take the opportunity to ask something else on this 3 metre business. A fire surveyor some time ago told me FLT battery charging should be done 3 metres away from any wall. I knew chlorine gas was given off so there is a need to carry out COSHH Assessment but was not aware that anything flammable was given off ?

A charging battery gives off hydrogen and oxygen (not chlorine - no idea where you got that from) and so the process needs to be done in a well-ventilated area. The "3 metres from a wall" is rubbish though. We have battery chargers up against a wall to protect them from passing trucks. There is no issue with this as long as the area is well-ventilated to allow the gases to disperse rather than build up.

Thanks Heather - I haven't ever done a COSHH Assessment of the issue - just interested to know.

You get chlorine given off from lead acid batteries when they get contaminated with salt water/brine (ask the old WW2 U-boat crews, about getting depth charged!)

Chlorine is not given off in an industrial setting - but hydrogen and oxygen as previously indicated.

Does nobody not remember their schoolboy chemistry lessons about electrolysis - cathode and anodes etc?

OK - I did A level chemistry and my part 1 went into it in quite a lot of detail - should know better ! Leave me alone now - I've been beaten around the head enough !
