Rescue operation with blocfor™ R
The presence of a second operator nearby is
essential to carry out a possible evacuation.
The rescue operations to be planned must have been
studied before each scheduled use in order to define
the human resources and equipment to be used to
rescue the injured person within a period of less than
15 minutes. Beyond this time, the person is in danger.
