Work in “confined spaces” has a series of operational difficulties and problems concerning safety, primarily due to the reduced spaces which limit movement, the atmospheres/ environments suspected of pollution and the objective difficulty of completing rescue operations in the event of an emergency. The use of suitable devices, combined with specific education and training of the operators, must strive, in addition to arresting any fall, to guarantee the possibility of immediate evacuation in the event of an accident.

A – One of the possibilities of access in confined spaces takes place through the use of a tripod (or monopod and fixed/swinging crane) combined with a hoisting device so that in the event of an accident the operator can be quickly recovered. In any case combined use with a fall arresting system is necessary. Where the work depths are quite high and therefore it is not possible to use a recovery device with suitably long metallic cable, recovery can be managed through rope tackle systems.
