The Vaping Lounge: Stoptober 2017 Campaign

Public Health England advocates vaping in campaign for the first time

Today Public Health England have stated that they will promote the use of E-Cigs as part of their Stoptober quit smoking campaign for the very first time.  Although it has been a couple of years since PHE came out and said that vaping was at least 95% safer than smoking they have been reluctant to endorse it.
This is great news not only for vapers but for smokers looking for a proven way of stopping as it may just reinforce what a lot of people have been saying for years now about the benefits of vaping and perhaps dispel a few myths that have been wrongly banded about among the ignorant. Stoptober is an smoking cessasion campaign held annually in October (surprisingly!) by the NHS/PHE for those who don't know.
It's certainly true that stopping smoking with the use of E-Cigs is more likely to be successful compared to using nicotine gum or inhalers. I know of at least ten people who have managed to quit the fags this way and with relative ease.
Its all good

And in other news NHS Health Scotland have came out today and said that E-Cigs are 'Definitely' safer than smoking cigarettes in a bid to clarify the harms and benefits of vaping.
More welcome news for the advocates who have worked tirelessly to get the message across about vaping up and down the UK over the past few years.

So far vaping has been recognised as a safer alternative to smoking by The Royal College of Physicians, NHS England, NHS Scotland, Cancer research UK and Public Health England. (there could be more). Its a step in the right direction.

Im all for it.

Polish OM-14 Gas Mask

Poland

Polish OM-14 Gas Mask Kit

Manufacturer: Maskpol SA, Konieczki, Poland
Face piece model:  Maska przeciwgazowa OM-14
Filter model: Filtropochlaniacz FP 203/1 - IV/W
Country: Poland
Year of production: Mask: 1989. Filter: 1993 or 1997?
Size: 3 (large)
Production run: 1954 -1989
Issue:  Ludowe Wojsko Polski (Polish people's army)
Price: £10.00 + £3.40 postage
Condition: New/Unissued
Source: Private ebay seller
Shipped from: UK

The OM-14 was one of those masks which I never really rushed out to buy.
As I already own several polish MUA and soviet GP-5 gas masks it wasn't a priority for my collection.
That was about to change when during a late night ebay trawl this handsome  specimen hoved into view.
A new and unissued late 1980s OM-14 complete with filter, hose and haversack.
The seller on ebay was asking a tenner for it so I snapped his arm off without question. It's difficult to get a decent mask in good condition for a tenner these days so I wondered if the guy really knew what he was selling?


The face piece

This look of this mask may be very familiar to some as its almost identical to the hugely mass produced soviet Shm-62U or GP5 as its more commonly known.
Contrary to belief it isn't a copy of the GP5, in fact the OM-14 was first produced in the decade before the GP5 came out.  More on the history of the mask later.

The mask is constructed from a single piece of thick latex rubber.
Punched into the rubber are two glass eyepieces and an inhale/exhale piece.  The eye piece rims and inhale/exhale piece are made from a good quality zinc alloy unlike the steel used in other similar looking masks. This should prevent some degradation.
Inside the mask we have a pair of tissot tubes which run from the inhale/exhale piece to each eye piece. These tubes provide air to the eye glass to help prevent to build up of condensation. In practice this system tends to work but to  be on the safe side a set of anti-fog stickers are always provided by the manufacturer. They usually come in a little round metal tin. (which I didn't get on this occasion)

Longer snout than it's Soviet counterpart GP-5

There isn't a great deal more to say about the face piece really. Its made from good quality rubber and although its a size 3 and my usual size is a 2, it still fits quite well.

The soviet style hood masks are much better at making an air tight seal than more modern designed strap fastening masks. They also offer good all over protection as the hood stretches completely over the head.


The filter

A red E-014 canister

A red filter? I thought they were all green?
Indeed the overwhelming majority of the larger E-014  filters are painted a drab green colour.  There is a reason for this of course.
The green E-014s are full Nuclear/Chemical/Biological protection filters that are only issued to the military generally speaking. whereas the red painted E-014s are designed for short term emergency work or short term laboratory work.
Each filter does a slightly different job essentially.
 

I never knew they made two!

Finding a red E-014 filter in your haversack is indeed a rare treat! This is the first time I ever seen one in the flesh.
This fancy filter arrived in fantastic condition. the original bottom plug was still sealed and had not been removed.
The top cap had been opened for the purposes of setting the kit up for a photo shoot according to the bloke I bought it off.
Half way down the filter canister is a printed paper band which has a few instructions and warnings on it. Definately not your regular army issue.

Still sealed with MASKPOL SA label across the plug

According to the official paperwork the FP 203/1-IV/W filter was intended to be used with the MUA, MC-1, MP-6, MP-9 and GSP-M gas masks.
Strangely I own five MUA kits and none of them came with the red filter?
Essentially the FP 203/1-IV/W is the same E-014 metal canister but with different guts. 

This pamphlet is pretty thorough

According to the manual this filter is effective against 63 nasty chemicals.

I'm not going to list them all but in amongst the nasties we have Sulphur Dioxide, Phosgene, Toluene, Amonia, Chlorine gas, Hydrogen cyanide and Hydrogen bromide to name a few. 

An ideal filter for emergency responders.

I also got a standard soviet style rubber hose for connecting the filter to the face piece but I don't consider that worthy of a mention other than to say that the hose is in good condition with no leaks.

Does this filter contain asbestos!?

As this filter was produced in 1989 then the possibility of there being any Asbestos inside are very slim indeed. The only problem with this filter is that it has expired.

The Haversack

The Haversack or carrier is your common or garden heavy cotton polish bag.  Nothing special, nothing to write home about. I have loads of these knocking about with MUAs and MC-1s in. These haversacks are actually OK. Everything fits nicely inside with some room to spare. The shoulder strap is fully adjustable allowing the filter to be used in the bag whilst attached to the mask.
Inside the bag are various pockets for anti-fog stickers or cleaning cloths.
Its a bag and it works.


Evolution of the Polish hood mask

MUA MK1, MUA MK2 and the OM-14

When it comes to Soviet style hood masks the Polish only really adopted one design, the original Soviet SHM-41M. The polish decided on an adopt and adapt approach to the SHM-41M and came up with the OM-14 in the early 1950s. The main adaptation was the lengthening and angling of the inhale/exhale piece. The exact reasoning for this change is largely unknown but I suspect it was to aid mobility. The "snout"  is angled away and down from the wearer's chin in comparison to the shorter SHM-41M snout. 

Later in the 1970s the OM-14 undertook another revision albeit only a small one. A round black plastic voice emitter was added to the nose area of the mask to aid communication. This additional part did make a huge difference to the mask.

The mask was renamed "MUA" to coincide with the change and this model would become the MUA MK1.

The last revision of the OM-14 came during the 1980s with the MUA MK2. This time the plastic voice emitter was replaced by a stainless steel one. 

Once again the reasoning for this change remains a mystery. When comparing both versions of the MUA it's hard to see any difference in the quality of speech.

Although the MUA was introduced as a replacement to the OM-14 mask, the OM-14 continued to be issued along side other models until at least 1989 making it the oldest polish hood mask in use.

Much better quality than a standard soviet GP-5

Overall this OM-14 kit is pretty special. A mask that in my opinion is the best of the GP-5 style hood masks.
It is also special because it has that rare and unusual red filter included (rightly or wrongly).
I think the ebay asking price of a tenner was an absolute bargain considering that a replacement filter normally costs about 6 quid on its own - and that's for a green one.


Rating: ✅✅✅✅✅ 5 out of 5
The addition of the fire engine red filter makes this 0M-14 kit stand out from the rest. The mask itself is in immaculate condition and looks like it was made yesterday.
OK its not the right mask and filter combination but only an anally retentive collector would be bothered by that.
Cheap price tag, interesting filter - you cant go wrong

The Vaping Lounge #3 - 18650 Battery Safety

18650 Lithium Battery Safety

Vaping as an alternative to smoking isn't dangerous. No where near as dangerous as smoking according to the Royal college of physicians.
It only seems to become 'dangerous' when some numpty carelessly explodes a battery in their pocket or something. Every few months you hear a tale about a woman in the states who got her handbag blown to pieces because she threw an 18650 lithium cell into there along with her house keys and loose change. Or a guy blew a hole in his face because he shorted his battery in a mech mod etc.
These 'accidents' are few and far between thank goodness but its always going to happen where there are ignorant people about.
The reasons for these mishaps are varied but they generally always involve a torn battery sleeve, a mechanical mod or the wrong type being used.
So here is a quick guide to keeping your vaping batteries in a safe state. I wont go into too much technical depth, I dont have to.... because the steps listed below explain everything in a simple way.

#1 - Use the correct type of 18650
For the beginner, finding the right 18650 cell for vaping can be a nightmare. not only is the market swamped with a million different brands its also swamped with completely unsuitable 18650's too.
Its not a case of buying the cheapest on ebay or going for the highest output. Its actually those types that will probably cause you the problems.

So first up are my recommendations of 18650 cells that will be completely safe and work in almost every vaping device you care to put them in.



Batteries to buy

 These are among the best mainstream high output 18650's

The best quality 18650 cells are generally manufactured by five big electronics companies. These are Sony, Samsung, LG, Panasonic and Sanyo.
Cells such as Efest are rewraps of the aformentioned companys. There are many other brands who don't make their own cells but buy them in and re-skin them. Its common practice in the e-cig vaping world. 

 Most quality vaping batteries have a flat top positive terminal

At the time of writing this post the highest capacity of a single 18650 cell is around 3600mAh. The vast majority of the cells that I own are only 2500mAh or 3000mAh capacity.  A higher capacity cell doesn't always equate to a longer lasting cell though. In my experience the higher 3000mAh cells tend to discharge at a faster rate.

 A continuous current draw of 20A is suitable for most devices

The Efest battery in the picture above is basically an LG or Sony 3000mAh cell with a purple wrap on it.  The pulse current draw says 35A and its maximum continuous discharge is 20A. Its the continuos discharge figure you want to be looking out for as you use the cell continuous when you press the fire button on your vape device.
20A should be the absolute lowest you want from your cells as your vaping mod will want to draw that from the cell in most cases.
A good all round 18650 to buy would be the Samsung 25R. They have a maximum capacity of 2500mAh and a 20A discharge.
I must have about twelve 25R's knocking about and none have ever let me down.
Samsung 25R's are reasonably priced if you buy them online. The cheapest i have bought them at is 3.00 each but they can cost a fiver each on ebay.
They certainly won't break the bank in any case!




Batteries to avoid!

 A rogues gallery of shite right there!

And now we turn to the detritus of cells, the crappy snide examples found on ebay.
It goes without saying that not everything is what it seems.
As mentioned in the previous section the highest 18650 capacity is still under 4000mAh. This is due to the size constraints of 18650's and the current chemistry used in electrolitics.
So don't be fooled by any cell claiming to have 4000mAh, 4200mAh, 5000mAh or in some cases 9000mAh! these kind of figures are not physically possible right now.
Also don't be fooled by the cells which have a button on the top. I'm yet to find a suitable vaping cell that has this button on the positive terminal.
The top positive button seems to be a throw back to flashlights and flashlight batteries.

 Beware the printed bullshit

Another thing to watch out for in a shite cell is the often spurious chinglish written down the side of the wrap. No they are not protected cells, No they don't have a PCB onboard and no they don't have 'Sheef life'.

Oh look, button tops

The Truth
These type of cells can be bought on ebay for as little as a quid each but its a false economy. They never come anywhere near to their stated capacity. Most top out at under 1000mAh due to the amount of lithium wraps inside. They feel as light as a feather as they are mostly fresh air inside.

Would they explode if you tried to draw a high wattage/current from them? 
Personally I very much doubt it.
A regulated mod would refuse to fire the coil if the battery couldn't muster the required amps.
These weedy underpowered tubes of crap would just dissipate and flatten.
To be fair to these cells though, they are OK for using in flashlight. They don't last long mind you but they do work. Flashlights are no where near as current hungry as vape devices and so popping in a cheapo ultrafire would do the job.
The button top found on these inferior cells help with connection in some of the flashlights but they just wouldn't fit right in a mech mod or regulated mod anyway.
Best avoided.


#2 - Storage 

 Buy yourself a twin battery box - they only a quid!

Genuine 18650 cells are more powerful than you might think. have you ever seen one venting?
The 18650 cell is designed in such a way that the negative pole runs all the way from the bottom of the cell, up the side and to within a few millimeters of the positive pole. The only thing to keep the two apart is a white cardboard gasket ring resting on the top of the cell.
If something goes wrong with your top of your cell, the wrap comes away and the gasket fall out then you could be in trouble - especially if you are stupid enough to put a piece of metal across it. Get a tear along the side of the cell and make a connection with some loose change and the positive pin and the result is much the same.
So its advisable to buy a battery box or similar to stow the cells if you plan on transporting them in a bag or pocket. They cost peanuts to buy and might save you a few painful skin grafts.

Single cell rubber container - isolating both poles

#3 - Damaged Battery Wraps and Rewrapping

 A badly torn Samsung 25R

Its inevitable that one day your cells will pick up a nick or two along its wrapping.
Just the inserting and removing of cells from your device can put a tear in the wrap however careful you think you are.
Its not a good idea to continue using a damaged cell especially in an all metal battery holder (like a mechanical mod) Its not a good idea to put a short across the cell in any circumstance so what do you do about it?

 Remove the old wrap and keep the insulator

• Buy some battery wraps off ebay
• Carefully peel off the old wrap and keep the white ring insulator
• Slide the bare cell cylinder into the new wrap -it should fit snuggly
• Get a hairdryer and switch it on at the highest setting
• Starting at the top, slowly heat the wrap all the way down 
• DONT forget to put the old ring gasket in the top before you heat it!
• that's it, all done, as good as new!

Apply a new wrap using a hairdryer

Regularly keeping an eye out for rips and tears on your cells is the right thing to do. as complacency could spell disaster.
Battery wraps cost pennies so there really is no excuse for sloppy maintenance!

Conclusion
I think i have kept this post down to a minimum? I could go on for hours but I don't think it would add much more to the general message here.
Its a simple message too..... Buy the right 18650 cells for what you plan on doing and look after them when you do.
Best of luck!

Fungold HG-1412W Multi-Charger

Fungold Multi Purpose Battery Charger

Manufacturer: Xiamen Nanfu Electronic Technology Co Ltd
Model: HG-1412W
Country of origin: China
Price: £5.00 + 88p postage
Shipped from: China
Condition: New
Description: Multi-type battery charger
Voltage: 110V-240V
Selectable Charging Voltages: 1.3V, 1.5V, 3.6V, 4.2V
Output: 1.5A
Batteries charged: AAA/AA Ni-Mh   + 18350/18500/18650 Li-ion
Safety Protected?: Yes
UK Legal?: No
EU Legal?: I doubt it

My latest product from the people's republic comes in the form of a 'all sizes' battery charger.
Presenting the Fungold Multipurpose Charger, A five quid battery charger that promises to recharge any size (and chemistry) of battery you care to throw at it with a few added safety features for good measure.
It all sounds too good to be true and the item certainly doesn't really look up to much but first appearances can often be wrong.....

 AA's, AAA's this thing charges the lot!

The HG-1412W is made from a strong plastic. Not ABS style by any means but thick and heavy gage it would appear. The overall construction is actually quite good considering the pocket change price you pay. It feels robust enough to take a few knocks and falls without cracking the outer case. Something I would consider quite important when a live mains current has to flow through it.

Four large stiff battery holders sit side by side along the front of the unit. These are accompanied by four equality stiff springs which act as size adjusters for the batteries.
A (poorly marked) voltage adjustment slide switch nestles in between the Cell holders to taylor the charge voltage being placed into the cells. This is user adjustable and some degree of care is required when setting up each type of cell to be charged.

Each cell holder has a cooresponding red LED light above it to indicate the current charging state. and a green LED sits in the middle to show that power is going to the charger. pretty simple stuff.

The HG-1412W has the ability to charge both Nickel-Metal Hydride and Lithium-Ion cells and in various sizes too.
AA and AAA Ni-Mh sizes and 18350, 18500, 18650, 26650 (?) Lithium cell sizes. A one-stop shop when it comes to charging your shit.
I must admit, I haven't come across a charger quite like this before.

Vaping 18650 lithium cells being charged

Operating the charger is really easy. Just select the voltage you want to charge the cell at, insert either 1,2,3, or 4 cells and plug it on the wall.
The red LED lights will show that the cells are connected correctly and thats it.
When each of the cells has fully charged the red LED lights will switch off.
Some cells may finish charging before others in which case the power is cut to that cell and it sits dormant until all the others have finished charging.
The charger incidentally has polarity protection built in so the cells shouldn't short out if they are inserted the wrong way up.
The HG-1412W is fully automatic and almost idiot proof!

Good Points

• Charges most rechargable Cells
• Ability to charge 1/2/3 or 4 cells independently
• Reasonable build quality
• Compact size
• Cheap! 

Bad Points

• Not UK legal
• Some safety concerns
• No instruction manual
• Thin power cable for 230V 

Illegal? Really?
Unfortunately the rather fantastic Fungold charger is not legal for sale in the UK (and probably Europe too)
Firstly because it hasn't had any official safety testing in the EU and doesn't feature a CE mark.
Secondly it doesn't have a three pin plug top on it - a requirement of UK law.
Instead it comes with a standard US two pin plug which is workable via the aid of a travel adapter.

Questionable Safety
Consumer safety is not always high in the list of features when a product is designed in China.
And although the HG-1412W does have rudimentary battery and mains protection it does have one major safety issue in my opinion.
No its not the dodgy thin power cable or the quality of the internal electronics, its the voltage setting switch.
Anyone who forgets to set the slide switch correctly could have a bad day if they get it wrong!
You see, if they happen to charge any non lithium-Ion cell like a AA or AAA and leave the slider set to anything over 1.5V then.... well you know whats going to happen!

Voltage selector slide switch

If the charger is solely being used for one type of battery then I dont see there being a problem. Its set for that voltage and left at that voltage.
It just becomes a concern when the charger is being used for multi types.
The device is safe enough for what it has to do, its all done electronically.
Its only when human interaction is needed (like a manual slide switch) that a risk is involved.

NEVER leave the charger unattended when its in use. just dont.
NEVER leave it on charge when you go to bed or pop down to the shops.
NEVER charge different types of battery in the HG-1412W at the same time.

Bring your own UK mains plug

Overall then I'm really happy with this product. It does everything a 15 quid charger does for a third of the price.
Yeah I guess it doesn't have a fancy company name plastered on it or come with a UK legal plug but I can live with that. It just has to charge my vape batteries after all.....nothing else.

Rating: ✅✅✅✅✅4 out of 5
If you are prepared to take a few risks when it comes to safety then this charger is a great value device.
Despite its obvious short comings it works really well and does exactly what it say it will.
Its cheap, Its basic, its no frills and it will charge your vaping 18650's without breaking a sweat.
Just keep your eye on it when its plugged in and you wont go wrong.

British GD MK6 Respirator

Cold War Crap

British G.D. MK6 Respirator

Manufacturer: Avon

Model: MK6 Respirator

Year of manufacture: 1956 (mask) 1953 (filter) 1944 (haversack)
Fitting: 60mm filter

Country: Great Britain (UK)

Production run: 1950's - 1960's

Vendor: private ebay seller

Price: £10.99 + £3.40 postage
Condition: Used
Size: large
Availability: Relatively easy to find

Introduction

The G.D MK6 respirator is something of a mystery. It appears that very little is known or has been published regarding the development and introduction of this apparatus except that it frequently gets confused with the older British MK2 light anti-gas respirator. Hardly surprising when you consider the amount of similar looking variants made by the UK at the time. It's easy to get them muddled up.

What is known for certain is that the MK6 is essentially identical to the wartime MK2 except that the voice emitter on the front sticks out rather than sticks inward and the air filter is a 1950's design.

The GD MK6 is based on the MK2 paratroopers gas mask first issued in 1943. It was (I think) the first british gas mask to feature a 60mm side mounted filter which did away with the whole hose pipe and canister arrangement of previous models. The benefit of this system was better freedom of movement for the soldier.

The light anti gas MK2 and later MK3 style of mask was a successful design which saw continued service for many years after the war. 

Production seems to have continued into the 1960's before being finally replaced by the Avon S6. 

Many surplus unused MK2 and MK6 masks were flogged to the Danish civil defence who were at that time looking to save money. 

The much loved and collectable Canadian C3 gas mask was based on this mask.

  

This particular MK6 was listed on an ebay auction a few months ago. The seller started the bid price low and the result was my winning it for the reasonable price of roughly 14.50 which I didnt think was too bad at the time.
After a few days the mask arrived in a nice packaged cardboard box.

The Face piece

The face piece is constructed from good quality rubber. The usual standard that comes from a british Avon manufactured mask. The eye pieces and voice emitter are well made too.  Despite the face piece being around sixty years old its in remarkably good condition. I suspect it has always been stored in its haversack rather than being on display somewhere judging by the quality. The face piece was originally designed to be both comfortable and practical for the wearer and this is certainly true if you try it on. It sits nice on the face and forms a good air tight seal. Avon have a reputation of high quality and workmanship and this post war piece lives up to that.

No it wasnt made in 1952... a red herring!

The face piece features two large round eye pieces which offer a good field of view. The voice emitter on the front is functional and communication through the mask is audible but not the best example of voice transference i have come across.

The inside of the mask is quite basic in its concept. There is no inner rubber mask for a fuller fit which is sometimes found on other masks and there are no Tissot tubes to help keep the eye pieces from fogging up.  Just the exhale valve/voice emitter is built in.  Its basic but very well made.

GD MK6 actually made in 1956

Im still trying to find out what 'G.D.' means when referenced to this mask. Im assuming it means 'General Duty' or 'General Distributed' mask perhaps? The lettering found on this mask doesn't seem to stand for anything obvious unlike the GSR 'General service respirator' or CD 'Civilian Duty' naming found on earlier british masks. 

I'm still researching this so any updates on this will be posted here.

Head harness replaced in 1965

Perhaps the single biggest mystery concerning this gas mask is its head harness.

Was the harness replaced in the 1960's as the date might suggest? Gas mask folk lore suggests that because the british had masses of these masks hanging around after the war they were recommissioned or kept in service by having the rear head harness replaced? The head harnesses were elasticated and could break or become loose so this could have happened. 

The Filter

The filter which accompanies this mask is the L. MK3 produced in 1953. The filter manufacturer is unknown at this point but it would have certainly been a UK company who made it. 

It has a 60mm thread diameter and screws on to the left side of the face piece. 

It doesn't seem as large as some of the US style 60mm filters. I'm thinking of the american M-9 gas mask filter in particular. 

A smaller  60mm could be beneficial to the infantryman who doesn't want a big round filter in his face when he is trying to sight up his rifle.

Its essentially a charcoal based NBC filter designed to be effective against a vast number of nasty toxins. Certainly everything the soviets could throw at you during the cold war years.

⚠⚠Does this filter contain Asbestos?!!⚠⚠

According to my research no white or blue Asbestos was used in this type of filter. Only Charcoal was used as the NBC filter medium. (But don't quote me on that!) 

Looking very similar to the american 60mm filters the L MK3 (Light mark 3) wasn't as bulky but still featured the same protective inner layers. The filter which features here is in very good condition with no signs of any degredation. This could be rusting of metal, loose stuff inside or dust/particles falling out of either open end. This particular specimen seems to have survived quite well.

The Haversack 

The haversack which holds the mask and filter is in fact the oldest part of the whole kit!
Yes, this musty old green bag pre-dates the mask by about 14 years.
The haversack was originally made in 1944 to hold the original light anti-gas MK2 respirator kit.
So many of these haversacks were made during the war that the surplus were kept in storage and then later re-issued with the newer, more modern masks and filters. It was essentially a simple way of keeping costs down at a time when the UK was still recovering economically from WW2. 
I don't think a haversack was ever designed exclusively for the MK6.

An old MK2 haversack. 1944 vintage

The build quality of this old MK2 haversack is really quite surprising. It's not your usual cheap shite material. 

Its made primarily from thick canvas with a huge dollop of heavy stitching thrown in. It feels hard wearing and well made.

The haversack features a good solid shoulder strap, brass webbing fittings and internal accessory pockets. 

I can see now what the government was thinking...What was the point of designing a brand new haversack for your 1950's masks when you have a warehouse full of these quality things from WW2?  Makes perfect sense.

Overall then this is an interesting mask for the collector. A well made gas mask and filter from the cold war kept in a well made bag from the second world war. I think this kind of pairing is quite unique in the gas mask world.  The GD MK6 isn't the rarest of gas masks but its certainly one for the collection.

Rating:  ✅✅✅✅4 out of 5

Avon gas masks are fantastic, whichever one you choose and the GD MK6 is no exception. If you see one on ebay buy it.....
