This is take 2. In a school, wibu to think that a room next to a tank room which smells strongly of fuel should not be used for 1:1 sessions for young children. Would you be happy with your 6 year old spending an hour in a room which smelt strongly of fuel (I think diesel but not certain)? And more specifically if 6 year old had had significant problems with lungs/asthma when younger?
A quick google search indicates that fuel is odourless and perfumed to make its presence known so any odour at all suggests the gas is present, though no idea to what extent. Does anyone have decent knowledge re this?
