PPE for vaporisers

[Hachi]

I wear nothing as i don't find it necessary, when any vapour appears i do a sensible thing and stand in the opposite direction to where the very small amount of vapour is blowing, now if i was to crawl into a card board box and vape myself i may well wear a dust mask.

Good for you

I only vape my hives now. My inspection boards have been in for weeks and I've only seen two varroa on one board. I did vape my hives over four weeks at five day intervals and posted my results.
Getting back to wearing PPE. I use a recessed bottom board slid under the OMF. I then seal all the entrance with foam and all the openings to the bottom of the hive again with foam. I vape for two and a half minutes then disconnect from the battery and leave for a further 10 minutes. Very little vapour escapes the way I do my hives. I stand down wind but I do wear a gas mask with a filter and goggles. The vaporiser has a two and a half meter length cable so that helps you keep your distance. I do wonder though if you seal the hive up correctly whether full PPE is needed as your not vaping in a confined space.

your not sticking your head in the hive, your stood in a field or at least in an open space.
your are operating it from a few feet away and containing the vapour for a while
the permissible exposure limit is 1mg /cubic meter so I can not understand why some go into this as if going to war you would need to be exposed to 50 times the exposure limit 50mg/*cubic meter before needing this sort of level
a half face mask for up to 10 mg /cubic meter exposure

your only using 3mg per hive !

Any chance of a linky to this "permitted exposure"?

err NO
3g per hive..


On that basis your advice appears wrongly based and you might like to consider withdrawing it...

Is there a model which you can buy more replacement filters instead of a use for a month and throw away?

It comes in a resealable bag. I let it dry out after using and I reckon, if you look after it, it will last ages.

I have only ever vapourised oxalic in the many years I have had bees. Tried trickling just once and abandoned that as a sensible practice, opening the hive up in cold weather and giving them a dose of a sticky mess!! AND I HAVE NEVER PUT ON A MASK OR GOGGLES for the simple reason that I take due care and attention of the ambient situation etc. What else!!!! Some just like dressing up to look the part - like SWMBO when she helps in the garden.

Ok I made a typo and put 3mg by accident instead of 3g, also you are containing it within a closed space so what amount is likley to escape to atmosphere ? precautions should always be taken but I feel there is no need to overcook the soap
The best first protection from anything is to be sensible and properly ***** the situation

sorry not withdrawing it as it is a comment and not placed as advise

Hi MBC
every processor has there own but they are pretty identical especially the control perimeters here is the one from sigma

Hmmmm

Precautionary statement(s)
P280 Wear protective gloves/ eye protection/ face protection.
P305 + P351 + P338 IF IN EYES: Rinse cautiously with water for several minutes. Remove
contact lenses, if present and easy to do. Continue rinsing.

Respiratory protection
Where risk assessment shows air-purifying respirators are appropriate use a full-face particle
respirator type N100 (US) or type P3 (EN 143) respirator cartridges

What the individual actually does is totally up to him/her as it is, in all honesty low(ish) risk in the open. but it's obvious from these two snippets that to advise (from a self proclaimed status of expertise) on an open forum that no PPE is necessary is IMHO irresponsible and reckless in the extreme (especially taking into account the intelligence level of some reading it)

Just had a quick look at it. looks like it is a pretty harmless molecule.

in comparison: this is the one for another one that is a lot scarier than oxalic acid and I use it in my kitchen without gloves or goggles...

http://www.sigmaaldrich.com/MSDS/MS...roductN=0%20220003048%20219853286%20219853121

wikipedia teaches me that with 300g of spinach or 500g of carrots, I ingest the full oxalic acid dose for one hive (3g).

quick, someone call a doctor, I had carrot coriander soup for lunch.

this being said, I would avoid chronic exposure as in combination with Calcium it will cause kidney stones and I would rather not want to find out how it feels to pee those out...

I also use glacial acetic acid as well, not in the kitchen though, and usually wear safety glasses to prevent any splashing in my eyes.

on your chips it is called vinegar...

never said that pure oxalic was not corrosive and should be put in your eyes. it will hurt if inhaled or come in contact with mucosa as does acetic acid/vinegar in its pure form (glacial).

 

[jenkinsbrynmair]

It's this Laissez-faire attitude amongs the beekeeping fraternity is probably the main reason that the NBU and others are reluctant to endorse OA sublimation.

Ah...thought you were on about the safety of glacial acetic acid going by hazzards link you put on, not the diluted form of vinegar.

Reading this I can't say I blame them in that respect, surprised they made it legal.

 

[REDWOOD]

don't use a WWII gas mask as the filters are made from asbestoses, little did they know then

Moldex do very good respirators for industry, whats really handy about them is any part can be replaced if the supplier stocks all the replaceable parts. Just looked on their site and what they recommend for oxalic acid is as follows:

http://www.moldex.com/pdf/datasheets/chemicalselectionguide.pdf

Filter Type

Generally indicates what type of filter and/or cartridge should be used for protection from a particular substance. Remember these suggestions are not absolute.
Selection must be based on consideration of the work and use situation encountered in a particular environment.

“OV” means Organic Vapor

‘‘N’’ means Dusts and Non-Oil Based Mists



7000 Series Moldex filter suggested 7100 + 8910


Organic Vapor Cartridge

http://www.moldex.com/respiratory-protection/reusable-respirators/7000/cartridges/organic-vapor.php

N95 Particulate Filter

http://www.moldex.com/respiratory-protection/reusable-respirators/8000/filters-and-disks.php#


or


8000 Series Moldex suggested 8100 + 8910


Organic Vapor Cartridge

http://www.moldex.com/respiratory-protection/reusable-respirators/8000/cartridges/organic-vapor.php

N95 Particulate Filter

http://www.moldex.com/respiratory-protection/reusable-respirators/8000/filters-and-disks.php#


The face pieces for the above cartridges and filters come in small, medium and large, really anyone selling the vaporising equipment should also supply a mask that has been approved for working with the said substance.

Interesting first chemical on the list of suggestions is Acetic acid which requires full face protection with the 9000 series, don't want that stuff in your eyes.


Shop around they are sold all over the web this site shows the cost of them over here in euros.
