One of the worst processes for orrid niffs is stuff that's been working in an animal foodstuffs plant...fair makes you heave.
Just a point David. If you have to do that they have to supply those big vet's gloves, that go right up to your shoulder, as there is a danger of Hep B, which you also should have had shots for.
Secondly all pumps that come in for service should have been de gassed and have a data sheet with them, recording what has been through it.
It's a dangerous game, maintenance, David, I spent 30 years sorting peoples messes out and I saw some nasty accidents, one guy lost his knee through a pump exploding through not being de gassed.
I actually meant the "special" cow shit, at Doc's farm. Now that is fucking dangerous
