Personal Protective Equipment PPE
PSA-STRING-WORKAIR
The PSA-STRING-WORKAIR is used wherever activities have to be performed in a fall-risk area, and it is not practical to provide protection by means of a safety harness. This is especially the case when comparatively modest fall heights (1 to 3 metres) exist, and it is impossible or difficult to position anchor points.Examples of this include loading and unloading points from vehicles, installation tasks at fall heights between 1 and 3 metres, tasks on scaffolding, etc. The low- weight item detects the fall by means of sensors, and automatically triggers the airbag in milliseconds. Thanks to the airbag, the back, ribcage, and adjacent organs are protected from severe injuries. The vest is worn on top of or underneath normal everyday clothing, and can also be worn underneath the safety harness. This reduces the risk of injury in the event of a pendulum fall. The technology employed is widely used in the motorcycling and ski racing sports, and it has been appropriately further developed for the requirements of industrial safety.
The PSA-STRING-WORK-AIR, developed in Italy, consists of high-performance materials which are sewn together into a
vest in an intelligent design. The protective vest contains two gas generators triggered by a sensor. This sensor detects
an abrupt change in position, and triggers the inflation of the vest. For this, a change in position of at least 1.2 m is
necessary. Falls from this height therefore trigger the airbag mechanism. The vest has magnetic closures, width
adjustments at the side, and it can be supplied in various sizes. It includes a lithium ion battery which ensures that the
protective vest can be used for 18 hours and then recharged via a USB-C connection. The watertight IP54 connection
links the vest to the integrated gas generators. An LED display provides information about the vest s status and
operational capability.
Intelligent activation mechanism
The sensory system built into the protective vest detects exactly when a fall occurs, and activates the inflation of the PSA-STRING-WORKAIR in milliseconds. Comfort and convenience through design and technology
By means of FEM-analysis software, the design was optimised in such a way that the vest extends optimally in the event of a fall, and it can be worn comfortably during normal use. Extended period of use in any weather
Once fully charged, the vest is ready to be worn for up to 18 hours on top of or underneath the everyday clothing.
