High Energy Debris Fall Protection Cushion
the challenge
Falling Equipment, Objects and Debris
In industry sectors such as mining, power generation, aerospace, infrastructure and construction, working around vertical shafts, ducts, or deep voids poses a safety challenge.
When debris, tools, or valuable equipment accidentally fall from significant heights, they gain dangerous speed and force. Without proper protection, falling objects can cause severe damage to infrastructure and equipment and put workers at risk, leading to costly project delays and maintenance downtime, as well as serious worker injuries.
THE solutioN
High Energy Debris Fall Protection Cushion (HEDFC)
The High Impact Energy Debris Fall Protection Cushion (HEDFC) is a multi-zoned, airfilled system designed to absorb the force of falling objects from excessive heights. It uses a multi-zone design to catch falling objects, such as debris, equipment, or tools, thereby protecting workers and equipment during maintenance work.

ZONE 1
Ballistic Cloth Membrane Impact Layer
Zone 1 comprises a primary air chamber covered with ballistic cloth, a high-strength,
technically woven fabric chosen for the ballistic properties that prevent it from being
pierced by objects during high-velocity events.
This layer is used to contain falling debris or objects and to absorb and diffuse the impact
force across the entire cushion in a controlled manner.
ZONE 2
Zone 2 comprises two interdependent parts: the main air chamber housing and an array of individually inflated shock absorbers.
Upper Compression Air Chamber
The chamber is constantly inflated to approximately 1.6 kPa. When the impact force is transferred from above, the compression air chamber, together with the shock-absorbing array, significantly reduces the falling velocity.
Array of Air-filled Support Shock Absorbers
Within the compression air chamber is an array of upright, air-filled supports that act as shock absorbers, allowing each support to compress independently to absorb impact pressure.
ZONE 3
Zone 3 is a shared air reservoir at the base of the system that dampens pressure changes.
