The lists which are utilised are of two types:
•
list of dangers (as in EN 414 referring to EN 292)
•
application of essential safety requirements (Machine Dir. - att. 1, part 1)
The following is a list of dangers which have not been fully eliminated but which are considered acceptable:
♦
in the version of the pump without a release it is possible to encounter squirts of oil (for this reason
appropriate protective clothing must be worn)
♦
contact with oil -> see the requirements for the use of suitable personal protective clothing
♦
use of unsuitable lubricant -> the characteristics of the fluid are shown on the pump and in the manual
(
in case of doubt contact the Eng. Dept of Dropsa Spa
)
