As a long time safety professional, any company who were to make a claimants position difficult due to a claim, would be in far more bother.
We had about a dozen instances of HAVS and every year, we used to issue the guy's affected with special gloves for wearing under their regular PPE. Working in the food industry shouldn't prevent the wearing of appropriate protection, for the significant risks encountered, or to protect against the worsening of a HAVS condition.
Also, any right minded employer must, by law, provide health screening. This should include checking for the symptoms of HAVS, industrial deafness, eyesight, and for anyone concerned in the use of solvents, weekly skin checks.

Health screening is usually done by outside companies with experience in assessing what physical problems are encountered for a particular job, so they know what they are looking for.
From what I understand, Hand Arm Vibration Syndrome, is treated like all the other workplace induced disabilities and a claim is made against a collective of employers, not just the one. (In the case of somebody who has had several employers).
There are specialist firms who will take on cases like this, so no one should be scared to make a claim, if they are suffering.
Also, the HSE are notified of anyone suffering from HAVS, this is not to drop the company in the $hit, this is to ensure that the company changes it's work practices, so that nobody else has to suffer, what is a very painful and uncomfortable condition.
This is just one of many ailments, (Asbestosis, Deafness, Various Cancers), which are entirely preventable, if the proper controls are in place.
A lot of companies, and I have heard the argument, say that it "costs too much to put these controls in place".
But it costs a damned sight less than a lengthy claim through the courts, resulting in a big payout for damages, along with your company name being wrecked through negligence.
I'm not disputing that British Gas fell foul of the courts , but the National Coal Board were also hammered. Air tools causing HAVS, respiratory problems, due to the dust and industrial deafness.
The irony there is, the person at the helm when all of the problems started to come to the fore, was one Lord Alfred Robens, who was commissioned to write a report on industry self regulation. This was published in 1972 and led to the creation of the Health and Safety at Work Act in 1974.
Health and Safety at Work Act 1974, section 2.
Employers shall ensure the health, safety and welfare of their employee's, while at work, at all times.
(Or words pretty close to that effect).
