SAFE AND UNSAFE USE OF HAMMERS IN A WORKSHOP
V. Ryan © 2003 - 2021
Hammers are used regularly, when working in a workshop. Special hammers are available for use with different materials such as plastics, steels, woods and other groups of materials. All hammers must be used with care.
The pupil opposite is irresponsible. He smashes two hammers together, because he likes the noise. He is unaware of how dangerous this can be. The hammer heads are made from cast steel and they are specially hardened. When the hammer heads smash together they can spark and even break into many small dangerous pieces. The small pieces fly off at high speed and damage anything they hit.
|This pupil has started to use a hammer without considering safety. As he raises the hammer he hits himself in the face.|
|The same pupil tries a second time to use the hammer. Again he is careless. He holds the nail in his hand but misses with the hammer, hitting his hand with the full force. He is not concentrating on striking the nail.|
|Hammer heads are normally fixed to the handle by a wedge. If the wedge becomes loose, this will eventually lead to the hammer head flying off, when the hammer is used. The head will fly off at great speed, which means that it will inevitably hit something or someone. If it hits a person, it can cause serious injury. Always check the hammer head before using it and report damage immediately to the teacher. This pupil thinks he knows best and his friend gets hurt as a result.|
