Vetter LD 50/30 Operating Instructions Manual page 11

9 Tension the leak sealer with the tension belts.
9 Make certain that there is nobody within the area of danger.
9 Inflate the leak sealer from a safe position until the leak is
sealed.
Danger of explosion! If there are inflammable liquid or gas leaks it
is imperative that sparks be avoided by fixtures and fittings.
Vetter sealing must only be filled when in the correctly tensioned
condition. Only fill the leak sealing until the leak is sealed (max.
operating pressure 1.5 bar and 12 bar). Any additional filling of the
leak sealer can damage the pipe or the tank by built up pressures.
A leak in a container or pipe is a weak point. Therefore avoid any
additional damage by filling the leak sealer so that no more liquid
or gas escapes. This can be the case at a point lower than the ma-
ximum permissible operating pressure.
Before application of the leak sealer, cover sharp edges and/or
pointed positions in the area of the leak by using dimensioned
sealing plates. In doing this you avoid damage to the leak sealers
as well as unintended escape of dangerous liquids and gases.
The Vetter Leak Sealing Bags LD 50/30 come in two different versi-
ons each having different tensioning possibilities available.
