Questions and answers - Health and Safety
People should avoid unnecessary contact with liquefaction silt. If people must work with it, the Canterbury District Health Board advises the following precautions:
- wear water proof gloves, gumboots and a dust mask
- shower or wash immediately afterwards
- wash contaminated clothes separately after use.
The procedure for sewage contaminated silt is as follows:
- residents should call the Christchurch City Council contact centre on (03) 0941 8999 with the details of the problem
- ideally those details should include an approximation of the volume of silt and the area to be decontaminated
- the ground will be sanitised as part of the process
- the service should be completed within two days of the request
- sewage contaminated silt will be removed at no charge
Silt arising through liquefaction on private land is the responsibility of the resident/property owner to dispose of through the local transfer station. The charge for this is $25 per tonne until January 2012.
