Hazard And Hazard Management Construction Essay

Hazard And Hazard Management Construction Essay The construction industry is characterized by a relatively high injury and illness rate compared to other industries. In the past two decades more than 26,000 U.S. construction workers have died at work. That equates to approximately five construction worker deaths every working day. Safe practices can help eliminate the hazards present in the construction industry, and reduce the number of on-the-job injuries and deaths. The techniques in the construction industry have been improved due to the rapid development of science and technology. However, the constructional hazards are not decreased as expected. To reduce or prevent occupational hazards in the construction industry, some methods were proposed to provide a prevention and improvement technique against occupational hazards. A method was developed to identify important hazard types and hazard causes. Additionally, especial analyses were performed to assess the risk value of the hazard. 2. Hazard and Hazard Management: Hazards identification is the act of identifying the failure conditions or threats which could lead to undesirable events. It may be outlined as a condition, object, activity or event with the potential of inflicting injuries or sick health to personnel, injury to property, loss of fabric, or reduction of the ability to perform a prescribed operate or combination of those (DOSH, 2006). Paul Everitt and Anthony Price (2004) define hazard as à ¢Ã¢â€š ¬Ã¢â‚¬ ¢any source or situation with the potential to cause harm to the safety and health of people or damage the environment or to plant / equipment. Because the existence of a hazard is not always obvious, and increases with human interaction a structured and systematic approach is essential in compiling a comprehensive list of hazards. The hazard management means, the method of implementing counter measures to decrease the chance of hazard. 3. The project features and their relation to the construction hazard To determine that how the project features contribute to construction hazard, it needs to categorize the project to the specific project features and breaking that down into a sequence of stages, and then, identifying all possible loss-of-control incident that may occur during the construction work. 3.1. The project features and the sequence of stages: Foundations: Excavation Pilling Structural activities Concrete Slabs Cast-in-place concrete columns and walls Erecting pre-cast slabs Erecting pre-cast walls Forming walls with stone cladding Finishing activities: Brick masonry Stone cladding Exterior plastering Gypsum boards Floor tiling Roof insulation Roof sealing Glazing Other activities Electrical installation Plumbing HVAC installation 3.2. Some sub-activities of the above stages are: According to the above category there are some sub-activities that would be hazardous in construction sites such as: Activity Sub-activity Hazard Event Foundation Excavation Cave- in Collapse the excavation wall Piling Sequencing of piling work Conflict with other parts of the project construction, creating unsafe working conditions Piles located in positions in restricted working space Personal injury from falling debris, crushing. Unsafe removal of guards or auger cleaners. Risk to third parties Piling near to the top of slopes Slope failure, rig overturning Working in excavations Access ramps and wall props can hold up working space Structural activities Concrete Slabs Slips, trips Fall Cast-in-place concrete walls with stone cladding Pouring concrete using a crane bucket Filling bucket Concrete spatter Exterior working Preparing the wall area Filling holes Dropping an object Casting lightweight concrete for drainage Casting concrete Pouring the concrete Dropping an object Concrete columns and walls Fix steel rebar cage Final ties Collision with steel bars Drywall construction Erecting the framing Attaching studs to exterior masonry or concrete walls Spatter of debris from drilling or nailing Exterior stucco Manually applying an insulating layer Curing and cutting protrusions Struck by a tool Cast-in-place concrete columns and walls Installing forms Cleaning and greasing forms in height Fall from a ladder Concrete columns and walls Casting concrete with a crane Lifting a bucket full of concrete Crane collapse A researcher argued that, according to the fatalities statistic, 40% of that involved incidents related to falls from height. Inadequate, removed, or inappropriate use of fall protection equipment contributed to more than 30% of the falls. As these statistics indicate, safety in construction remains a big problem. As good safety practices and records create a positive, hazard free, and productive work environment, planning for safety at the front-end of a project is not only the first but also a fundamental step for managing safety. There are some hazard identification tools, such as: Text Brainstorming Checklist Structured What-if (SWIFT) 4. Some Common Construction Hazard Issues: 4.1. Construction Hazards: Construction hazards may include falls, extreme heights, falling from rooftops, machinery failure, unguarded machinery, being struck by heavy construction equipment, electrocutions, silica dust, asbestos, lead, welding emissions, accidents, structure collapse, roofing and pavement tar, engine exhaust fumes, and other hazards. Construction sites include residential construction, bridge erection, roadway paving, excavations, demolitions, and big painting jobs. 4.2. Construction Hazard Statistics According to OSHA : Figure 1 shows that falls from elevation generally represent the leading cause of a death due to construction related activity, representing about 33% of all construction fatalities. Getting struck by some object, caught in-between two objects, and electrical shock is also leading factors of construction fatalities. Together, these make up about 90% of all construction fatalities. It is important to note that over the last few years, these numbers have statistically declined or increased in a linear, proportion fashion. The occupational Safety and Health Administration (OSHA) Statistics show that about 90% of the fatalities occur from four types of injuries. These injuries may be from falls from height such as scaffolding or ladders, being struck by objects, being caught between objects, and electrocution. There are other common hazards in construction sites that may include power tools and equipment, Heavy machinery, excavations, and confined. 4.3. Is the Engineers and Safety Staff are blame? Failures in hazard identification are often due to the limited expertise or oversight of engineers or safety staff when planning or executing safety practices, or poor training of construction staff. Examples are tasks in design for safety, safety inspection, and monitoring safety. Failure in any of these can result in increased risk of exposing workers to hazards in the construction environment. Safety planning in construction is generally done separately from project execution planning and involves different actors. This separation and the resulting lack of communication create difficulties for safety engineers to analyze what, when, why, and where the hazards located for preventing accidents. 5. Fall Hazards Identification and Preventive Measures: As mentioned above, 40% of involved incidents are related to falls from height, due to that here will focus on Identifying and assessing the hazards and risks as an essential step in safety management. The potential fall hazards regarding to construction features are, holes in slabs, leading or unbounded edges of the floor slab, and openings in walls. According to OSHA a slab hole means a gap or void of 2 in. (5.1 cm) or more in its least dimension. A hole can exist at several heights, for example, on a floor (e.g., concrete slab), a roof (e.g., skylight), or any other walking/working surface. Similar rules exist for openings in walls, for example, unprotected windows. Regardless of the size of the hole or opening, if the location of the object is elevated more than 1.8 m (6 ft), it would be hazardous. The preventive measure for falls include, always using appropriate fall protection, installing and maintaining perimeter protection when working from heights, covering and securing all floor openings, and following safe practices when using ladders and scaffolds. 6. Conclusion: The construction industry has been considered an accident prone industry. Alarming statistics indicate that the construction industry accounts for 55,000 fatal injuries each year. That is because construction sites are often filled with potential hazards that can lead to serious injury or death. Safety planning can be considered in the scheduling stage for early detection, including identification of a hazardous location, and schedule for implementation of protective safety equipment. Construction sites, unlike other production facilities, undergo changes in topography, topology and work conditions throughout the duration of the projects. These features make managing construction site-safety more difficult than managing safety in manufacturing plants. Mostly in construction, a different approach is needed to identify hazards and risks, increase safety and prevent accidents. The employee is responsible for reporting any defects in the workplace or on any of the equipment that is being used. A workplace inspection is a critical part of a comprehensive safety and health program in which the workplace is examined closely on a regular basis for the purpose of: Identifying and recording potential and actual hazards associated with buildings, equipment, environment, and processes. Identifying hazards which require immediate attention. Ensuring that existing hazard controls are functioning and recommending corrective action.

Brand Comparison Paper Essay

Pepsi Co. and Coca-Cola have been in business for a long time and both are largely successful companies in the beverage industry. They both have different brand components in comparison. A few of the different comparisons would be pricing, quality, packaging, logos, brand equity and features. In the following paper we will discuss these items in detail to see how different these two brands are. Pricing Strategies Looking at the pricing strategies of PepsiCo and Coca-Cola they are taking two very different plans. The products they sell are similar with variations in taste and the brand war in the soda market has been to out discount your competitor to gain market share. The issue with giving deep discounts is that your digging into profits which could cause both long-term and short-term issues. Pepsi has realized the short-term strategy of deeply discounting products over its brand portfolio is not a sustainable business model for the long-term business needs. PepsiCo has changed its view from the short term to the long term and was in a transition in 2013 that slowly saw the company stop offering discounts but switch to a hybrid everyday value strategy. The hybrid strategy closes the gap of holiday price points and its regular price point to provide a better value for the customer very day and not just wait for sales to purchase the product (â€Å"Reuters†, 2013). Coke on the other had is still out performing PepsiCo and other competitors even in 2014 so their outlook is different. The large reason for their performance is the heavy discount strategy that is continuing to be implemented. While it is successful in the short-term it leaves the soda giant open for long-term financial issues (Cooper, 2014). Comparing the two while Coca-Cola is winning the short-term war currently PepsiCo is setting itself up for better long-term gains and growth. PepsiCo is able to see the  value in the future of its company and understands it had to change the way it does business which would cause a short-term set back while introducing its new pricing strategy. However, the long-term value of doing this will keep the company in business and profitable for many years too come. Differences in product quality As far as quality difference in the two products it really is a matter of taste, which is either acquired or just something a person likes. An example of an acquired taste one is like the household a person grows up in drinks Coca-Cola then their taste buds may come to like the product because that is what they were offered in the house. Which for either company doesn’t represent a quality issue in reality but because of brand loyalty they may deem Pepsi or Coke better than the other product. Pepsi has a distinct sweater taste than Coke, which has a hint of vanilla flavoring, higher carbonation, and sodium per swerving (Mertz, 2013). The lower carbonation and sodium makes Pepsi a slightly higher quality product in the not so healthy soda industry. Product Packaging When it comes to Pepsi versus Coca-Cola, these companies have been competitors throughout the years. Both companies have come a long way with their advertising slogans. Coca-Cola’s first slogan in 1886 was â€Å"Drink Coke† and has changed many times over the years to today’s slogan â€Å"Open Happiness† (Coca Cola Journey, 2012). Pepsi’s first slogan in 1939, â€Å"Twice as much for a Nickel† promoted great pricing (G&M Distributors, Inc., 2012). Today Pepsi’s advertising slogan is â€Å"The Best Drink Created Worldwide† (G&M Distributors, Inc., 2012). These two companies could not be any more different is their logos, symbols and colors. Coca-Cola’s main logo has not changed much over the years, sticking with the cursive Coca-Cola font (Coca Cola Journey, 2012). Pepsi, on the other hand, has changed their logo many times over the years. From the Pepsi-Cola cursive font to the Pepsi bottle top, and more recently the Peps i half red and half blue globe (G&M Distributors, Inc., 2012). Product Image and Personality Even though these companies are vastly different in there branding they are very similar when it comes to image and personality. Both companies are concerned with sustainable packaging, recycling, and making an impact of the future of our globe and its environment. Coca-Cola has a commitment to â€Å"set the standard for sustainable packaging, achieve zero waste in our operations and recycle more packaging than we use† (Coca Cola Enterprises, 2014). Coca-Cola uses targets such as using less packaging, using recycled materials, PET bottles, recyclability of their packaging, manufacturing, and inspiring consumers to recycle to assist in keeping our environments clean (Coca Cola Enterprises, 2014). Coca-Cola also uses campaigns like â€Å"Recycle for the Future† to inspire communities to recycle (Coca Cola Enterprises, 2014). Pepsi also concerns them with less packaging, turning waste into wealth, recycling, and motivating others to recycle (PepsiCo, n.d.). Both companies want to improve what they are doing as a company to help improve the environments in communities where they are located. Distinguishing Features Pepsi Co and Coca Cola are both known for offering similar colas that have competed to be consumer’s favorite soda for decades. Pepsi Co most recently has been seen as a more attractive brand to a younger audience than the well-known Coca Cola. Pepsi Co is known for many products beyond Pepsi cola but is easily recognized by the red, white, and blue logo. Besides the noticeable difference in logos Pepsi tends to have a sweeter taste and a citrusy flavor burst. (â€Å"Lubin†, 2012.) Almost everyone has a preference when it comes to choosing between Pepsi and Coca Cola. â€Å"There is a great comparison which says Pepsi is a timely brand and the other brands are timeless brand. So one is for the older people, one is for the younger people.† (â€Å"The Economic Times†, 2013.) Brand Equity A brand has positive brand equity when consumers react more favorably to a product and the way it is marketed when the brand is identified than when it is not. (L.K. Keller, 2008.) Consumers have known both Pepsi Co and Coca Cola for decades. Consumers have tried their products and collected their memorabilia as a supporter of each brand. Although Coca Cola has proven to  be the more successful brand Pepsi Co has not given up. Pepsi Co also has shown success with their sports beverage, Gatorade and bottled water, Aquafina. Pepsi Co has continued to make necessary changes in order to remain competitive and build brand equity. Conclusion In conclusion, although these two brands are largely successful in their own right they also have very different brand components. We were able to research and distinguish several of them to include pricing, quality, packaging, logos, brand equity and features. References Cooper, T. (2014). The Montely Fool.

There are a number of relations which have been proposed to do this inversion. These relations have been derived from the basic Zoeppritz equations which are nonlinear. In order to be efficiently incorporated in reservoir modelling software, it is desirable that the inversion is linear in nature. Some simplifying assumptions are made in deriving these linear relations. These assumptions are not always satisfied in real earth. Synthetic seismic reflection data is first generated and then inverted using the different linear relationships. The efficiency of these relationships in obtaining model parameters will be determined and the effect of lithological changes on inversion efficiency will also be examined.

Essay on Socrates - 1116 Words

In Crito, Plato recounts the last days of Socrates, immediately before his execution was to take place in Athens. In the dialogue, Socrates’ pupil, Crito, proposes that Socrates escape from prison. Socrates considers this proposal, trying to decide whether escaping would be â€Å"just† and â€Å"morally justified.† Eventually, Socrates concludes that the act is considered â€Å"unjust† and â€Å"morally unjustified.† Socrates then decides to accept his fate and proceeded with his execution. Socrates was a man who was in pursuit of the truth (Durant). In his refusal to accept exile from Athens or a commitment of silence as a penalty, he chooses death and is thrown into prison. While Socrates is awaiting his execution, many of his friends, including Crito,†¦show more content†¦Socrates’ argument moves from one of a general moral decision to the morality of his specific case. He basically says: -One ought never to do wrong, -But it is always wrong to disobey the state, -Therefore, one ought never to disobey the state (Durant) Since avoiding the sentence handed down by the jury would be disobeying the state, Socrates decides not to escape. Socrates chose to honor his commitment to truth and morality, even at the cost of his own life. One of the main arguments made by Socrates, â€Å"Think not of life and children first, and of justice afterwards, but of justice first...For neither will you nor any that belong to you be happier or holier or juster in this li fe, or happier in another, if you do as Crito bids.† -Socrates (Wolff 45), is one of the most important and crucial statements in the Crito dialogue. Socrates provides a very convincing argument of why he should not escape from the Athenian prison. He states that if he does as Crito suggests and escapes, it will not be justifiable or true, and he will be contradicting his own teachings. Although his family and friends will be much happier if he escapes, he will not follow the justice or moral code of the state in which he was born and raised. Socrates also gives the idea that if he were to escape, his family and friends would be happy for him, but their fellow citizens and their state in which they reside would not.
