Quote Egg Banjo="Egg Banjo"The employer is legally required to make reasonable adjustments. In the case of the goggles analogy, this could include the use of other eye protection types or models, proving protective shields etc. As none of those were shown in the analogy, the sacked employee would win an employment tribunal for unfair dismissal.'"
Can I just remind you that you wrote the analogy
Health and Safety requires removal of the risk and if that is not possible a fully risk assessed alternative can be considered which could be a change in working practise, grills or shield along with PPE and they would have to cooperate 'reasonable adjustment' is not a method used in safety. Your goggles fearing chap would lose a tribunal, assuming he has the money to start it
Even though you have added a few extra bits to the initial post and the task before it escalated you still come up with the the wrong answer but his safety is paramount and if the only way to guarantee it is to remove him from the task so be it, no doubt they would seek to find another role in the company to suit someone with a fear of safety goggles.
As for 'reasonable adjustments' I am assuming you've picked this up from the Equality Act which requires employers do this for people who may need additional support in the work place be for people with disabilities.
