A Few Facts about Ladders
You would have to be living under a rock not to know what a ladder is. They can be found in nearly every home and most work places. But, did you know that a painting of a ladder was found in a cave in Spain over 10,000 years ago? Yes it's true: a ladder has been seen in a Mesolithic rock painting that is at least 10,000 years old. The picture shows two humans using a ladder to reach a honeybee nest to harvest honey. Ladders really have been around for that long and in this post we want to share some other interesting facts about ladders with you. OK so let's start with a definition. A ladder is a piece of equipment consisting of a series of bars or steps between two upright lengths of wood, metal, or rope, used for climbing up or down something. Today, ladders are mainly made from either fibreglass or aluminium. But, when ladders were first made, they were usually made from tree trunks or woven vegetation. Wooden ladders are still available but 9 times out of 10 we would choose aluminium or fibreglass over a wooden ladder. There are two main types of ladders available. Firstly there are rigid ladders, these are often leaned against vertical surfaces like walls and secondly there are rope ladders which are often hung from a surface. Usually rigid ladders are portable but in some circumstances they can be permanently fixed to buildings. There are many benefits of using an aluminium ladder, but it's important to note that you should never use an aluminium ladder if you are working with electricity. (Unless you are using a ladder with insulated feet). Many people will be aware that aluminium is a conductor of electricity but not many people will realise they could get electrocuted through a ladder if it comes into contact with electricity. So please be careful.
When working with electricity, fiberglass ladders are the best choice. They are also a great choice if you have had problems with dampness, rot or bending previously as aluminium ladders can be weakened by exposure to dam, salt air and chemicals. But, fiberglass ladders are more expensive and do weigh more. So why would anyone pick aluminium over either fiberglass or wooden? Here are our favourite facts we like to share with our customers about aluminium ladders; wooden ladders are much heavier, aluminium ladders are more long lasting, they're also lower cost and finally aluminium ladders are flame and water resistant. Next we move onto the sinister side of using ladders and we're going to mention injury. Do you know the most common injury from ladders? It's probably not what you are expecting, but the most common injury is in fact bruising. Fractures and head injuries are also up there but the most common injury is bruising, sustained from falling off a ladder. Another fact that may surprise you is that in the the European Union and the United Kingdom there is an established ladder certification system. It currently has three different classes; Class 1 ladder, Class EN131 ladders and Class III ladders. Class 1 are for heavy duty, industrial uses and are colour coded blue, Class EN131 are for commercial uses and are colour coded green or yellow and Class III are for light, domestic uses and are colour coded red.
Rope ladders are used when space is limited and have weight restrictions. Climbing these ladders also requires far more skill than climbing rigid ladders because of the fact the ladder likes to swing. Boarding ladders are used on the side of boats to climb in and out from the water. Pool ladders are used to climb in and out of swimming pools. There are also assault ladders which are there to be used in covert operations and vessel boardings.
