How to use the Mining Vertical Escape Chute ...

The evacuee has full control of the speed at which they descend!

  To use the Vertical Escape Chute :

 

  • Sit on the edge at the entry point with your feet and lower legs in the chute  -  at this stage, you will feel the inside wall of the chute grip your lower legs

 

  • Expand your legs against the inside wall of the chute  -  you will feel considerable resistance

 

  • Whilst supporting your body weight with your hands, lower yourself into the chute, keeping your legs fully extended against the inside wall of the chute

 

  • Once your shoulders are in the chute, push your hands and arms against the inside wall of the chute and bend your legs at the hips  -  this action will slow your descent  -  by applying enough pressure you can come to a complete stop (and just sit there!)

 

  • To descend further down the chute, relax the pressure against the inside wall of the chute​

Increase Pressure

= SLOW DOWN

OR STOP

Relax Pressure

= SPEED UP

How the Verti-Scape Escape Chute is made ...

 

The Verti-Scape Escape Chute is manufactured from three completely separate and distinctly different fabric tubes / chutes.

Each tube / chute has its own function to perform and it is ONLY when these three tubes / chutes are assembled together, do they then become an Escape Chute.

  VERTI-SCAPE ESCAPE CHUTE ASSEMBLY  

  NOTE  

 

There is a space between THE OUTER LAYER and THE MIDDLE / BRAKING LAYER  -  this allows air to circulate between the two tubes, thus preventing heat transfer.

  • The 'outer layer' of the escape chute is to protect the evacuee from fire / flames and radiated heat  -  it can withstand a constant temperature of between 550°C - 600°C.  The outer layer will only start deteriorating at 810°C.

    THE OUTER LAYER

  • The 'middle / braking layer' is the layer that makes the system work.  It is an elasticated tube which is approximately 300mm in diameter in its rested form, however it has the capability to expand to 600mm as the evacuee travels through.

    THE MIDDLE  /  BRAKING LAYER

  • The 'support chute' gives the escape chute its strength to hold the weight of evacuees as they travel through.  This layer has loops stitched into the top of which a stainless steel rolled pipe is inserted.  The pipe is then held in place by a recess in the deployment device.
