Hi we currently have a plumbing team with undertake day to day internal plumbing activists but who may also be called upon to assist unblocking external drains/sewerage pipes upon our site. I am interested as to what vaccinations those person working in the sewerage industry are offered by the employers and what other companies offer in relation to these tasks (I have taken guide from the Clear Water guide 2010). Obviously our RA states contact should be minimised by wearing appropriate PPE and by using external mechanism rods/ sewer cameras etc.
