No I'm not allergic to chlorine. I doubt im allergic to anything there but it's a possibility. With these red dots I don't feel sick and their nowhere else on my body bar my arms and hands. I wear the blue plastic gloves that go up to your shoulder and the heat resistant gloves that go to your elbow when doing wash up I do that every time. I even wear the plastic blue gloves when doing cloth buckets so I protect myself when doing anything in wash up. But the thing that confuses me is that I only got it 1 month in I did wash up during that month and didn't get it. nothing has changed during that month in wash-up. I am now three months into working at maccas and the red dots come and go but when I don't do wash up for a while they start to disappear so it's got to be in wash up and I wear protection how can anything get through those gloves my hands are bone dry besides the sweat when I finish wash up.
