Well, I found this (not exactly Dettol, but a compound that predominantly makes it up)
In 1952 Joseph (9) conducted the first LD50 study with PCMX. From intraperitoneal injections in mice of PCMX in aqueous solutions the LD50 was 2.88 g/25 g mouse. Using the Reed-Muench formula the LD50 was determined to be 120g/kg and the minimum lethal dose (MLD) was 115.2g/kg.

Hope that helps any chemistry majors figure this one out.
Either way, I'd say that he'd have to be breathing it in every breath of every day for years.
