Construction Safety in the uses of Lifting Appliance (LA) and Lifting Term Paper

Construction Safety in the uses of Lifting Appliance (LA) and Lifting Gears (LG) for Foundation Works - Term Paper Example Violation of these rules may lead to accidents and injuries, especially when dealing with lifting appliances and lifting gear for foundation works. The main activities pertaining to safety in construction are: the proper organization of the construction and operations; organized storage of materials and components: the organization of the site and passes, ensuring the normal operation and emergency lighting of the working area, the organization of technical supervision of the state mechanisms, crane tracks, proper functioning of all construction equipment; a systematic coaching staff; compulsory fencing of areas and stairs, as well as rotating and moving parts of the crane, compliance with the rules of operation of the crane in accordance with the Instructions for installation and operation of lifting devices, use of alarm accordance with the rules pertaining international construction safety laws, and last but not the least, ensuring electrical safety. (Prichard, 2001) One of the mo st important documents that provide trouble-free maintenance works in construction is a project of work organization.  This project takes into account all safety measures that are indicated in the document, including heavy mechanization and labor-intensive work on horizontal and vertical transportation of materials, types of used construction materials and their placement on the site, and the inventory of the forest, scaffolding. Storage of construction materials is allowed only in areas of projected work organization .Indiscriminate storage of materials, products and equipment is prohibited.  Gaps between warehouses and piles are installed in accordance with the requirements of fire-fighting equipment. (Opfer, 2008) At the construction site, pointers driveways and walkways must be installed.  Walkways and driveways for working machines must be free: blockage of materials or waste is not allowed. The width of driveways for one-way traffic shall be not less than 4 m. Aisles bet ween stacks of building materials should be at least 1 meter in each pile should be kept only homogeneous elements. There is serious risk when using lifting gear (LG) or lifting appliances (LA), which can lead to accidents.  Therefore, the zone within which the working crane is dangerous and must be fenced. Since the handling of lifting appliances and lifting gears is a dangerous activity and can be fatal in case of an accident, safety measures concerning their management must be taken into consideration. In this paper, we will talk about Safety concern in Reversed Circulation Drilling, Crane Rotator, the risk assessment and hazards associated with LA and LG. (Prichard, 2001) Controlling LA and LG The main objective of controlling an LA or an LG is to ensure the safe movement and precise stop load-bearing body at a given height, and, if appropriate device, to ascertain the smooth supply of goods into the building. The Hoist driver manages to land the keypad, a 5 to 30 m from the b ase of the lift (depending on the height of the building), or auxiliary control panel located at a carrying a lift. (Opfer, 2008) The driver of the lifting appliance or

The Power of Poetry Essay Example | Topics and Well Written Essays - 1250 words

The Power of Poetry - Essay Example To prove the potency of poetry, the poem chosen here is called ‘Aunt Jennifer’s Tigers’ and it was written by Adrienne Rich. This paper seeks to prove how poetry can be used as a powerful medium to convey much more than pretty verses. Poetry can be a vehicle for social critique, literary expertise and so much more. ‘Aunt Jennifer’s Tigers’ is a relatively short poem of twelve lines that tells the story of the poet’s Aunt, a nervous and diminutive woman who lives in terror of her husband. It has a rhyme scheme of AABB with no variation. This rhyme gives it a very simple, almost childlike quality that belies its serious content. Another great thing about the choice of the structure for this poem is its short length. The brevity of the poem reinforces the tragic brevity of the life of Aunt Jennifer in the poem. Thus, it can already be noted that even the most apparent features of a poem can be of significance and hold more meaning than meet s the eye. To move into the poem itself, the first lines are: ‘Aunt Jennifer's tigers prance across a screen, / Bright topaz denizens of a world of green.’ The first words echo the title of the poem – again, much like a nursery rhyme does, reinforcing the irony of the childlike style against a grim subject. The lines also introduce the subject of the poem: Aunt Jennifer herself and her ‘tigers’. From the use of the metaphor ‘prance across a screen’, one can hazard a guess that these are either tigers that Aunt Jennifer embroiders or knits. The imagery of ‘bright topaz’ against a ‘world of green’ is very visually evocative and also serves the purpose of setting up a contrast that will tie in with the theme at a later point. The lines following these may come as a bit of a surprise to the reader. After introducing the rather pleasant scene of ‘prancing’ tigers of bright topaz, the poet writes: They do not fear the men beneath the tree; They pace in sleek chivalric certainty (Rich 3-4) This negation of fear does not ‘naturally’ follow a description of something. In usual conversation perhaps, or in prose, one would not jump from describing ‘prancing’ to ‘they do not fear.’ This sort of jump in logic to achieve an end – one that will be cleared by the end of the poem – can only be achieved with such mastery and simplicity in poetry. The lines introduce an element of gender. ‘Men beneath the tree’, given the context of tigers, evokes an image of hunters or hunting – a traditionally male activity. ‘Sleek chivalric certainty’ reinforces this image of hunters in their uniforms and presents a picture of masculinity. The oppression of women in a patriarchal world is the major theme of this poem and it is introduced here. Given this knowledge then, the contrast present in ‘bright topaz’ in ‘a world of green’ can appear to symbolize the visible nature of women in a world of men where they seem to ‘stick out’ and cannot blend in easily. The second paragraph of them poem begins with the identical phrase as the first, ‘Aunt Jennifer’s’ – this is a double reinforcing of the children’s nursery rhyme structure which usually has repetitions of phrases like these: Aunt Jennifer's fingers fluttering through her wool Find even the ivory needle hard to pull. The massive weight of Uncle's wedding
