Self-contained breathing apparatus can also be used in conjunction with an airline by way of a simple attachment. This could be used to extend the working duration of the set (overcoming some of the limitations of the cylinder duration) or as a long duration escape set should the airline supply be compromised. The 3M™ Scott™ ProPak consists of a set of pneumatics mounted in a soft, comfortable jacket. Cylinder duration options of 15, 20 and 30 minutes give the user flexibility, both in terms of weight and profile of the set. The 3M™ Scott™ ProPak range can also be used with an airline attachment. The advantage of this equipment is you can carry between 30-90 minutes of air as an escape reserve. Alternatively the airline system can be used to extend the duration of the BA set whilst the wearer is travelling to the point where he needs to disconnect and have the flexibility of an unconstrained BA set.
