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...

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...
