Just finishing my tea and I suddenly can smell plastic burning, I searched high and low for the smell. Then my light bulb went out, in closer inspection I noticed that the bulb is all brown and burnt and that's obviously the smell? I've turned the switch off. But I'm an anxious person and have pure O so now I am panicking! After a quick Google ot says get out th house because the fumes are toxic?? This isn't right right surely? Someone help lol my DH is at work. I'm 5'2 so even standing.on a.chair I can't reach to give the bulb. Help required!!
