• Risk Assessment
The proper use of the safety device described in this Operation Manual as
it relates to installation conditions and mechanical performance and func-
tions is a prerequisite for its use. When selecting or using this safety de-
vice, risk assessment must be conducted with the aim of identifying
potential danger factors in equipment or facilities in which the safety device
is to be applied, during the development stage of the equipment or facili-
ties. Suitable safety devices must be selected under the guidance of a suf-
ficient risk assessment system. An insufficient risk assessment system
may lead to the selection of unsuitable safety devices.
