imagine what female painters and decoraters would do if it weren't safe! they'd have to start their maternity leave at their BFP, haha!!
it's fine as long as your skin is covered, the room is ventilated and you wash your hands before you eat/touch your mouth to stop from transferring anything into your body. they recommend you don't eat in the room you're painting in just to make sure you don't put anything in your mouth, but i wouldn't fancy that anyway, with the smell of paint haha!
there is some information on the NHS website about it, check here. it really put my mind at rest:
