Hazards Associated With Deep Excavations

posts Associated With Deep ExcavationsHealth and Safety Task 2P3 Describe a range of identifiable hazards associated with deep excavations and scaffolding when on the job(p) from heights. Explain who may be at venture from these potential Hazards?Working from Heights When working from heights it is vital to remember to be re all(prenominal)y alert because of the numerous jeopardyinesss when doing so, on that point is quite a lot of professions that work from large heights, but the most common one in the construction exertion is scaffolding. So Im going to give you some modelings of hazards associated with scaffoldingF completelying from said height The hazards here argon obvious, depending how far you fall and what you hit when going down and of lineage how and what you land on all determine how much damage you will take. Now the simplest way to make for certain people dont fall of scaffolding is by having safety rails and barriers all the way around the platforms but th is can cost a lot of money if they make it completely protected all the way around, so they develop to make the scaffolders on site awargon of any certain beas that are more dangerous than others for example a mussiness where ladders are from the area below, an area that isnt as well protected as it isnt an area of high traffic. When talking ab come forward locomote from heights and who gets injured repayable to it this will rarely involve the public as they should not be climbing the scaffolding to be able to fall, so this will usually all effect the workers.Objects falling from height Objects falling from height is one of the main causes of injury and death in the construction industry, this is because of the nature of the items and the large heights that are used on site for example, a lot of bricks and iron poles fall from the top of scaffolding that could be as high as a 30m structure or even more, this is why P.P.E like hard hats were introduced because we identified ha zards like this and realised this was the best plan of action. Objects falling from height can be very dangerous to the passing public when in that respect is scaffolding being done on a busy main street for example, we now put measures In place so that the public has to be a certain distance away, as well as having netting theyre to try and catch the falling debris. obviously workers are as well injured and killed from falling objects quite regularly as well.Deep ExcavationsDeep Excavations is where you have dug a rather large lot that requires foundations to keep the ground from caving inwards and crushing what ever is inside. Now obviously this is very dangerous job because there are a couple of study risks that are involved for example, the ground caving in around you, lack of oxygen in the tunnels, and digging in areas of danger.Ground Caving In There is a great risk of the ground caving in while digging, the way around this problem is by creating foundations as you go al ong, these foundations will keep the sides from caving in, this is the most common danger when doing deep excavations, as sometimes people dont make strong foundations and the foundations could break leading to a cave in.Lack of type O There is a endangerment when working so low down that there will be a lack of oxygen, obviously we have found ways around this with Oxygen tanks and so on but, there is still a fear that the oxygen will be thin and cause you to pass out.Digging in areas of danger There is also the danger of digging in dangerous areas when digging for example an electricity cable running along the ground, or major water pipes could also cause serious problems if damaged when digging. So it is very important to check the area that you are digging in properly to make sure that there isnt anything that could cause problems when digging.P4 Review and evaluate the main principle features of a risk sagaciousness for these situations and determine the main differences betw een risks and hazards?Risk AssessmentsThere are four principle features of a risk assessment these areevery employer must take an assessment of the risk to their works and non-employees at work, the risk assessment that has been taken must then be reviewed in case there is any changes needed to it, and then specific risk assessments must be carried out on young persons employed at work. These principles are very important they are what makes risk assessments work, if you dont stick to certain principles for example things could go wrong Every employer must take and assessment of the risk to their works and non-employees at work, this is arguably the most important of the four as this is the base foundations for the rest, it is important to remember that the risk assessments that are taken are also for the public not just for employees. Secondly the undertaken risk assessment must be reviewed this is due to the fact that there could be a few risks missing, or on the other hand they m ight have added a few risks that werent there at all.There is also five main points to consider when doing a risk assessment these are Identify the hazards, decide who might be harmed, evaluate the risks and precautions to be put in place, then record your findings and review your previous risk assessment and update it.Difference between a Risk and a Hazard A Hazard is something that potentially has the ability to cause harm for example things like hot water/steam, electricity whereas a Risk is the likeliness of that said Hazard happening, for example electricity is being transferred threw a wire this is a potential hazard, there is no risk until the wire for example has been damaged, now there is a risk of being electrocuted so I becomes a risk.M1 Carry out a risk assessment for the task associated with the construction of a retaining wall. Remember to consider the 5 steps to a risk assessment.Introduction First before I actually do a risk assessment Im going to quickly excuse what a retaining wall is and make a diagram so it will be simpler to understand where I have found the risks and why I sop up them as risks.Retaining Walls A retaining wall is a style of wall that is used more specifically for holding back dirt/stone back from a certain building/area retaining walls if erected properly can be incredibly effective at fighting back erosion of the soil around the retaining wall. They are built by digging down and creating foundations and building the wall from the foundations up.D1 Justify your risk assessment strategy with adventure records and data available and explain how you have taken all reasonable and practicable steps for control measures monitoring that you believe essential.Measures In PlaceI believe that we have taken all steps that are essential to control the dangers surrounding building a retaining wall, with a deep excavation for the foundations of the wall. We have found every hazard that we obligate worthy of risk and rated said risk, we have put measures in place to make sure that these risks are avoided for example when digging an deep excavation there is great risk that the ground can cave in from the sides, we get around this by making sure that we have safe solid foundations, making sure that they are maintained is vital as its no good having foundations if there going to break due to negligence. It is clear that its essential to have the rightfulness controls in place as the construction industry is a very dangerous place. So in conclusion I believe we have managed to share every risk there, and as long as we stick to what measure that have been set we should be a lot safer than before.Data on accident recordsIt is important to back up the risk assessment with recent data as to prove that there is a decline in people getting hurt and that the measures that we are putting in place over the years are making a difference. The first set of results shows the amount of injuries due to falling from heights in t he construction industry between 1996 2008, the second set of results show the amount of injuries due to falling from heights in the construction industry between 2008 to 2009 it shows the three main types of injury, Fatal, Major and over 3 day injuries.
