A Few Thoughts On Safety Recalls

DMM Wales has recently announced a recall for some products which integrate their compact swivel design. Why do recalls happen? In general, safety recalls occur when a product could potentially lead to a situation resulting in a substantial risk of injury. This could result from a problem in the initial design and construction of the product or it could be from a problem which develops over time while the product is in use. There are risks associated with product design, development, and product...

A Hitch is a type of knot that is tied around an object and if the object is removed, the knot comes untied. Hitches are used for many purposes but one of the main uses is as a rope grab. This allows a rope to be attached to another rope in a way that allows the position to be easily adjusted.

Testing Pulley Efficiency

When using pulley systems, mechanical advantage is expressed as the ratio of the amount of output force to the amount of input force. For example, a '3:1' system has three times the amount of output force as the input force. If a person pulls with 10 units of force, this system will apply 30 units of force to the load. This allows a person to lift a load much greater than would be able to be lifted without the help of the system. This is the mechanical advantage. Rope rescue, rope acces...

Rope Rescue and Rappelling. What is the difference?

We often hear a lot of confusion over the terms 'rappelling' and 'rescue'. What is the difference? In simple terms, rescue is a way to help someone from a dangerous situation. Rappelling, or abseiling, is an access method. Rappelling is a way to use equipment to go from a higher position to a lower position. Rappelling can be a form of self-rescue to get yourself out of a dangerous situation but when helping others it is normally only part of a rescue. Why do rescuers rappel? Rappell...

RPM Systems. Are they still relevant?

We have previously written about some of the differences between rope rescue and rope access. Another major difference is rope rescue work is focused around team skills whereas rope access is mostly focused on individual skills. Rope rescue uses teams to raise and lower a rescuer and patient. An easy way to think about the difference is in rope rescue work the ropes are moving whereas in rope access work the ropes are stationary and the technician moves up and down the rope. The most comm...

Rope Rescue Risk Management

Rope Rescue involves risk. Rope skills are technical and if not performed properly can result in serious injury or death. Risk also comes from environmental conditions such as bad weather and low visibility. Rescue requires an immediacy in order to save a life which can cloud judgement. How can this risk be managed? A patient is packaged into a litter in preparation for being attached to a rope rescue highline. Rope Access Technicians use planning to help manage risk. Bef...
