Safetydrape® Blast Curtain

Using curtains as a protection against the effects of external blasts and the resultant airborne glass (or whole windows) is not new.

The British have, especially during the conflict with the IRA, been using curtains with yards of fabric sitting on the floor in the hope of capturing the lethal shards of glass.

What is different now is dramatic!

Safetydrape® is engineered from very high tensile flame retardant polyester yarn, knitted in such a way as to allow the shock waves of a blast to pass through the curtain whilst capturing the airborne fragments of glass. Those fragments are said to be responsible for 80% of the damage to humans in a blast event.

Unlike the British model, the curtain remains in place creating a parachute effect and gently drops the shrapnel to the floor (see video clip) The excess fabric required to form the parachute with Safetydrape is stored discreetly in a colour matched trough so the installation appears to be a conventional semi sheer window treatment.

One serious misconception is that only the target building is at risk. In fact windows can, depending on the strength of the blast, have glass come adrift in a radius of 1000 metres or more. Buildings adjacent to places of high target risk ought consider protecting their occupants.

If you wish to discuss protecting a facility our qualified fitters will gladly consult, anywhere or any time.

Oklahoma City Bombing Case Study

This chart, created after the Oklahoma City Bombing in 1995, shows how widespread glass breakage is in the event of a bombing or act of terrorism.

The A.P. Murrah Federal Building is shown in yellow and it is clear that glass breakage occurred many blocks away from the intended target.

Although the surrounding buildings were not specifically targeted, they were affected because of their proximity to the Murrah Building.
