Safety & General Advice
Ridgisewer and Ridgidrain ADS products should be transported, handled
and installed in accordance with the requirements of BS5955:Part 6:1980
and, for applicable contracts, the Highways Agency Manual of Contract
Documents for Highway Works and Sewers for Adoption.
Storage and Handling Recommendations
Pipes up to 400mm in diameter are supplied in pallets which should
be carried by a forklift or similar vehicle and should not be dropped
from the delivery or craned by their timber frames. If pallets are craned
soft slings should be used. Pallets may be stacked up to a height of 3
pallets as shown but only if carefully stacked on firm, level ground. Care
should be taken when cutting the steel strapping as it could flail and
cause injury. 450mm and larger pipes are normally supplied in individual
lengths but may also be palleted. Loose pipes should be stored between
securely anchored supports not more than 1.8m apart. Loose pipes
should not be thrown, dropped or dragged along the ground.
✘
Care should be taken to ensure that pipes, particularly those with integral
sockets, are not damaged during unloading and/or transport on site.
Extra care should be taken at temperatures below 0ºC.
Pallets or pipes should be supported at a minimum of two places during
mechanical handling operations and care should be taken to ensure that
they are not damaged by slings or forks. Hooks should never be used.
