Holy cow. BCF should not be used in an enclosed space (like an engine compartment) whilst people are in there....as it can be poisonous.

AFAIAA we don't use BCF/Halon on the Mainline railway anymore for that reason. Nowadays our extinguishers are CO2 (black band), Powder (blue band) and AFFF, which is short for Aqueous Film Forming Foam (cream band)

It seems to me that perhaps the Llangollen Railway are leaving themselves wide open for a charge of manslaughter if anyone tries to use that extinguisher on the engine.

Yer it looks that way..........lol..

The 66s don't have an engine room fire system, as there are sensors all around the engine room that shut it down if a problem occurs. There is an AFFF portable extinguiser in each cab.

Aren't green the long-since obsolete Halon extinguishers? I thought they'd been outlawed about 10 - 15 years ago. Certainly they must be very long in the tooth!! (A bit like me!) ;D

Edit: Sorry, didn't scroll down far enough to see the rest of the thread!

Slightly different tack
Can't remember whether it was 47's or 33's, if the batteries were flat and the
Fire Alarm Test
button was pressed, the engine room CO2 extinguishers discharged

Certainly all the ex-BR DMU stock I come into contact with is fitted with automatic 'fire bottles' which will deploy and soak the underframe if the fire warning system is activated, or can be manually operated by hitting a switch in the cabs. Plus the usual AFFF foam extinguishers on board. I hadn't realised that saloon extinguishers weren't a requirement, that's very suprising. A further improvement would be to also stow the emergecy tool cupboard contents in the cabs too!
