How the <strong>Blair</strong> <strong>VIP</strong> works<br />
<strong>The</strong> <strong>Blair</strong> <strong>VIP</strong> is a ventilated pit toilet. <strong>The</strong> toilet slab is made with two<br />
openings, one for the squat hole and one for the ventilation pipe which is<br />
fitted with a corrosion resistant fly screen. <strong>The</strong> vent pipe sucks out air from<br />
the pit and fresh air is drawn down through the squat hole. <strong>The</strong> toilet itself<br />
should therefore remain fairly free of odours if the toilet floor is kept clean<br />
and washed down.<br />
Flies approaching the toilet are attracted to odours coming from the pipe,<br />
but cannot pass the fly screen to enter the pit. Any flies escaping from the<br />
toilet are attracted to light coming down the pipe. But these will be trapped<br />
in the pipe. All <strong>Blair</strong> <strong>VIP</strong>s are fitted with a roof and a semi dark inside.<br />
