Thanks Sym!
Each time I try that in word,it asks for my product key number,which I don't know how to find,then it tells me I have only 25 attempts at this....blaa blaa...!
Webbtrekker,that is a mighty fine likeness of the real thing,even doon ti thi rivets aroond the top of thi Glennie,and the switch on thi side of his caplamp,wat switches
atween ya spotleet,and ya taaky - leet!![a smaller powered bulb,more sociable when you were taaking ti ya Marra's at bait-times...you didn't blind them!]
Note the "Bean-can" [as we called it!],on his belt.
"Self-Rescuer" to be correct.
It was a life-saver in the event of a fire or explosion underground.
They were made by Draeger-Normalair,of which the local factory is on the Bebside industrial estate,as you go up the slip-road ti the Bebside roundabout,on the left.
For those who are unfamiliar with this device,I will try and describe it and it's correct use....briefly,if I can!!!!!
Upon becoming aware of a fire or explosion on the OUTBYE side of you,i.e. with contaminated air being brought into where you were working,with a risk of breathing
CO..[Carbon Monoxide-"Afterdamp"],[which I just recently covered],you would quickly assess the risks with your nose!!
You wouldn't wait for an Official,such as the Deputy or Overman,to TELL you to put your bean-can on,you would do it with no hesitation...seconds count when you are dealing with CO!!
BUT,you would NOT,I repeat NOT,REMOVE THE RESCUER FROM YOUR FACE,UNTIL AN OFFICIAL INSTRUCTED YOU THAT IT WAS SAFE TO DO SO!
When in use,the canister containing Carbon Granules,and other minerals,converts CO into "breatheable amounts" of CO2..[Carbon Dioxide],which is not poisonous
like CO,[Carbon Monoxide,]and so renders the atmosphere to a safe level for life to survive,providing the wearer can reach a supply of fresh air very quickly,as the rescuer only operates for about one hour,and becomes unbearably hot while being worn.
It is a natural reaction to want to remove the mask,due to the heat,and the difficulty in pulling bad smoky air through it,because you can hardly breathe when under a stressful situation,and trying to hurry when underground,travelling through deep water,slipping and sliding over rough stony wet ground,is very difficult....even in a good supply of cleanish air.[never mind in a situation like this!]
So that's why the rule was brought in,[under mining "Rules and Regulations"],about waiting to be instructed when to remove your mask.
The mask was removed from the canister by pulling up on a metal "safety " strap,which held the two halves of the canister together,with the mask safely packed inside.
If,somehow,this strap got broken off or damaged in any way,you had to report it to the lamp-cabin man,to ensure you had a fresh one for your next shift.
Think!!,if you carelessly forgot,and threw it back into it's docket,then put it back on next day...........then it is needed in an emergency.......you've had it mate!!
Chemical reaction takes place the minute it is exposed to the atmosphere,so if the canister is damaged ,or the strap gets broken off,it takes about an hour,then it is useless!
Mind,they were the most-cussed device ever used by any miners working in very low seams!![in safe environments!]
They got caught on every single obstruction there was ,while crawling down a coal-face...timber props,hydraulic hoses [of which there were hundreds!],electric cables.......big stones...where there had been a roof fall and it was very narrow,or low,to travel through.....you would hear your marra's cursing!!...bliddy bean-cans!!!
When worn on the face,they were similar to war-time gas masks,without the freaky eye-holes!!...a clip over your nose to prevent contaminated air reaching your lungs by that route,and a hard mouth-piece which you "bit" on with a rubber gasket enclosing your mouth and cheeks,to seal it also.
Then any air you breathed in,entered through the canister of Carbon Granules,and if I am not mistaken,[maybe I am!],the canister also had Aluminium Oxide
crystals..[or granules....whatever!]
Hope I have painted a decent enough picture of how the "Bean-can"..."Self-Rescuer" saved lives in the event of the aftermath of a fire or explosion.
Not only Miners had these devices,anybody who might be exposed to CO ,such as firemen etc,would have these along with the equipment they would normally
use.
Might I add that the bean-can was useless in any other gaseous atmosphere,such as H2S [Hydrogen Sulphide-"Stinkdamp"...deadly poisonous!],or CO2,[Carbon Dioxide......"Blackdamp"...not poisonous...but asphyxiating as I already explained earlier].
Well,time to pile a few zzzzzzzzz's up again!
G'nite folks!
