Had my 1st midwife app this morning, during which i was asked to do a Carbon Monoxide breath test. I had a score of 7, which apparently is dangerously high. My OH was with me so he did the test as well, he scored a safe 2, ruling out our house and car as the cause. After a little discussion it was decided it must be my job. I've since had a phone call from the MW advising me i either need to change my job or ask for a full H&S assessment.. both easier said than done. Anyone else been through this?
