I have been asked if there is a successful way to extract the smell of onions whilst the company carries out the peeling process, does anyone have an example of how to do this?
This also made me question the long term issues with the onions stinging the eyes of the operators. Does anyone have any information on this?

Can't you buy onions already peeled?

The company we are talking about is the company that peel onions for other companies. The majority of the work is done by machine, but there are a number of employees who quality check the peeled onions. These are the employees that I am trying to find a control measure for.

Hierarchy of control applies and your employer needs to risk assess before implementing any PPE as this should, as you know, be a final option only. Couldn't your company purchase a machine that peels the onions? Just googled it and such machines exist.

My wife peels onions in a bowl of water.

I seem to recall the approved method is a spoon in the mouth and an item of clothing rubbed on a toad's belly.
I apologise for this and acknowledge the mods' view on it herewith.

Lets give you some perspective on this question, we are talking about 14 tonnes of onions per day. I think that there may be issues with opperators having their hands in water all, but I do see where you are going with that answer.

I hope and trust that you at the very least allow her to wear wellies.

Hw about some effective LEV?

OK that sounds like a good solution, does anyone know of a suitable LEV system that would fit over a conveyor line, that would affectivly extract the gasses produced by the onions?

If the onions are cold, a 'fish frier' type hood will not be effective as it relies on warm air rising into the hood. A push-pull system might work if the operators stand on one side only; air would be blown across the conveyor from the operators' side and captured by an extract hood on the other side.

You can fabricate captor hoods to go over an area that you want extracted. These can be pretty large. I suggest you talk to one of the larger LEV specialists such as Nederman.

George, you must be the authority on the smell of onions. In the experience of us amateurs who are replying, it is only the slicing of the onion that brings about the tears. The article I referred to earlier explains why that is the case.

How is the QC check being carried out at present, and what is it looking for?
Could the samples be kept in clear-view container of some sort, and just visually assessed, or do they need to be handled?

Yes I believe that any onion that have been missed by the peeling machine need to be finished by hand and then any damaged onions are then picked out for waste.

Firstly the problem with eyes watering is primarily due to absorption into the skin of the juice from the onion. The most effective way to deal with this is by wearing gloves.
However, if occlusive gloves (probably the thin, unpowdered natural rubber latex ones will be the best) are worn for long periods, the separate cotton gloves should be worn underneath to limit the problem of hyperhydration. This would also help to eliminate the risk of irritant and allergic reactions to the onions, something that is well established in the dermatological literature.
You could then peel under water, as the gloves would protect the hands.
Without actually seeing the workplace it is difficult to comment about LEV, but my feeling from having seen similar tyes of operation is that you would need to move large amounts of air and the carbon footprint and cost would be considerable.
