Does any of this apply?
Book an appointment
Arrange follow-up after discharge if cough, wheezing, fever, chest discomfort, unusual tiredness, or reduced exercise ability continues.
The article also says
If the person is unconscious, do not give anything by mouth.
Move them away from fumes only if you can do so safely.
Begin CPR if they are not breathing normally and you are able to do it.
Every sign above is quoted from the sofidex article on Lighter fluid poisoning. If you are not sure, err upward — it is always reasonable to be checked.
