A METHOD OF CREATING A PROTECTED ENVIRONMENT AROUND A WORK REGION, A PROTECTIVE CHAMBER FOR CARRYING OUT THE METHOD AND A METHOD OF PACKAGING THE PROTECTIVE CHAMBER

摘要

A method of creating a protected environment around a work region (3) comprises using an elongate protective chamber (5), for example in the form of a collapsible transparent sheet at least at its ends . When the outer ends of the chamber are attached by a web (13, 14), for example around the work area, which may be a cable (3), and that the gap between the attachment areas is somewhat lower the length of the stretched protective chamber, the protective chamber (5) can be pushed axially with respect to the work area, which provides a protected area extensive around the working area by a very simple means . The invention also comprises a protective chamber (5) of the aforementioned type and a packaging of said protective chamber method. During packaging, the protection zone is compressed accordion and the packaging is arranged to protect the buffer chamber when the latter is placed on the cable (see fig. 6). During use, a controlled atmosphere is preferably maintained by pipes (11, 12) in the protective chamber.
