Building and construction Safety Technology Assignment

Building and construction Safety Technology - Assignment Example The paper tells that the construction workers are the people who will be using the hoist frequently, and therefore more likely to be injured by the hoist. To avoid accidents that might be caused by their negligence, it is important for them to be trained on how to use the hoist and some safety precautions. A material hoist should be manually controlled by a well trained operator so as to ensure safety of other workers lacking the technical knowhow of a material hoist operation. All the workers should be provided with a simple list of do’s and don’ts safety information to reduce the risk of self injury due to carelessness. The material hoist must be designed in such a way that it is enclosed in a compartment which has openings on each floor which will act as doors. Each opening should have a landing plate which will clutch the hoist when loading and offloading. The material hoist motor should have a speed governor and an equipment to measure the weight of the load being lifted. The maximum weight to be lifted by the hoist should be effectively communicated to the workers responsible for loading the hoist to avoid overloading. The lubrication of the bearings and gears should be as often as possible to avoid friction and wearing out of joints and wheels. This will also ensure that the hoist motor is not overloaded and reduce the risk of malfunction. The material hoist should be suspended from steel wire ropes of highest possible quality which corresponds with the weight to be lifted. ... This will also ensure that the hoist motor is not overloaded and reduce the risk of malfunction. The material hoist should be suspended from steel wire ropes of highest possible quality which corresponds with the weight to be lifted. The steel wires should have an allowance for environmental factors such as cold and hot weathers which cause expansion and contraction of the ropes. If overstretched, the ropes may break during cold seasons. A number of steel ropes should be used so that when one breaks others hold the hoist before repair is done (Craighead 210). The minimum diameter of the steel ropes should not be less than 8 millimeters. Other requirements Sound reduction is one of the emerging trends in the field of escalators. The sound of a material hoist should be as low as possible therefore increasing the ability to identify a problem with the hoist when it arises. Sound reducing rubber pads should be installed to eliminate noise and vibrations that might otherwise cause weakeni ng of the beam and the hoist’s frame work. It is recommendable to use stainless steel for the material hoist housing since it has a relatively small weight and yet high capacity of not getting torn apart when lifting heavy loads. Unless stated otherwise, stainless steel should be of EN 10029, EN 10048, EN 10095, EN 10259 or EN 10258 grades 316 or corresponding. Question2. Crane Safety Precautions A crane should be properly maintained and repaired when damaged to avoid its malfunctioning while lifting loads. Before a crane can be employed to lift iron bars, its capacity should be considered. A crane which has a low capacity to lift the weight of the iron bars should not be used; otherwise it may cause injury to those operating it. The hoist rating of the crane should be
