2.5 General information
Compliance with all the applicable occupational health and safety rules,

2.6 Residual risk
Even when all the safety regulations are complied with, residual risks
remain when operating the cone pipe stopper, as described below.
As the owner/operator, make sure that all persons who work on and with
the inflatable pipe stopper system are aware of the residual risks. Follow
the instructions that prevent residual risks from causing accidents or
damage.
During operation of the cone pipe stopper, there are various residual
risks and potential hazards that every operator should be aware of:
During operation of the inflatable pipe stopper system, risks to
the operator may occur or the pipe stopper system and other
material assets may become damaged in the following cases:
- Operation and handling of the cone pipe stopper by personnel who
are not trained and experienced
- Use contrary to the intended use
- Improper maintenance
No modifications or conversions to pipe stoppers, filling devices and
filling hoses are permitted. The cone pipe stopper may only be operated
with genuine Vetter filling devices and filling hoses. If third-party parts
are used, safety may be impaired.
