I was exposed to a gas leak at school today. I was showing year 8's how to use the bunsen burner and I noticed a smell of gas. Not unusual as we were using the gas taps. However shortly afterwards I started feeling very dizzy and light headed. I called for another teacher to take my class as I just thought I was having another low blood pressure day. I lay down in the staffroom in the cool, had some water and biscuits. However when I went back into the class the releiving teacher told me they had found a leak. Thus I would have been exposed to a gas leak for about 10 mins.

I have felt fine this afternoon, just normal tiredness. Should I call the Dr or midwife? I see them tomorrow anyway... or is it more urgent?

Thanks for any help
