2.2 Information about the dangers
Any changes and reconstruction of packers, inflation fittings and
inflation hoses are not permitted. The operation of the Vetter Fle-
xible packer is only permitted with original Vetter inflation fittings
and inflation hoses. Other parts obtained from another source can
compromise safety.
Flexible packers are made of a strong expandable material.
If the packers are expanded above the maximum permitted range
then this can cause bursting. No persons are allowed in the wor-
king area during reconstruction and repair work.
After positioning the packer it is to be ensured that nobody re-
mains in the shaft or in front of the pipe during inflation, reconst-
ruction and deflation work.
