Safety Management Plan For Night Time Work Construction Essay

golosh Management Plan For darkness Time pop off accessible organisation EssayIn the previous in Chapter 1, the overview of this study was explained about and the problem was identified. Then from the overview, the aims of the study be to explore the challenges faced in formula site during dark cadence, to identify the different accompanimentors associated with gum elastic during wickedness- condemnation structure. Through the chapter, the elaborations of the topic are clearly described. The clarification of the sub-topic will studies about the dark time bend, stick outning aspect, and the impact of wickedness-time structure operations on preventive, quality, environmental factors, and productivity.2.2 Overview of Night live on2.2.1 Definition of Night roleplayAccording to Derek Simpson (2005), night tame is defined as a 7 hour period which includes that between midnight and 5am, usually 11pm to 6am. Anyone who normally whole kit at least(prenominal) 3 hours o f their passing twenty-four hours during this night period is classed as a night croper. Night workers should not work more than an average of 8 hours in every 24. Where such(prenominal) work involves any particular(prenominal) hazards or heavy corporal or mental strain the 8 hours limit applies to each 24 hour period, not an average 8 hours over the reference period.According to the North Region Construction Night Work Guide (2007), night work is the most difficult and challenging time for the avower to work to meet his contractual obligations and therefore the most difficult time for the inspector to en reliable the work meets the standards and levels of quality while also ensuring that everything is done safely.2.2.2 Safety Management Plan for Night time WorkA management plan should be well documented and structured so that both employers and employees toilet benefits from its use. The following are recommended components of a safety management plan for night time works(S ite force obligationIt should be de experimental conditionined and stated clearly in the safety management plan the responsibility of each individual at spin site for night time works. Project Manager, Engineers, Designers, Safety military officer and Site Supervisors as well as workers each have their specific responsibility to make indisputable the highest level of priority are given towards safety and wellness issues.Permission to work at nightPermission to work at night should be obtained from the relevant authority before reflection works at night is carried out. Employers should submit their application for work permit to Local Government Authority and it is wise to follow all requirements enforced by the authority prior to executing night time construction works. It is also recommended to notify the nearest police station, BOMBA, hospitals or clinics so that they potentiometer prepare accordingly in case of an emergency. It is also recommended that night work approved by the local authorities be sure to the residents/occupants of the surrounding neighbourhood.Inventory preparation for safety equipmentsBefore night works are carried out, check the entry of safety equipment to make sure they are adequately available, appropriate, and in good working condition. Purchase adapted new safety equipment for a new construction project or to add existing inventory. Equipments such as retro-reflective signage, barriers, retro reflective tapes and redness equipment are slightly example of safety equipment that should be provided for night time construction works.Material and Machine military campaign / coordinationEmployers should be aware that material and machine movement that is not well supervised could potentially sweat serious injury and harm to workers and properties.HousekeepingAccidents butt joint occur as a result of poor housekeeping. Hazards at construction site are the comparable for both mean solar day and night shift while the atte mpts of injury are more than higher during night works be pee of the inherent poor ignitor. It is essential that the workplace is kept clean and tidy to ensure safety and prevent accidents.Emergency Preparedness and Response (EPR) whiz of the most important elements to consider before work at night is carried out is the EPR specifically for night time environment. A well established EPR terminate help both employer and employees to prepare resolution and recover should a disaster occurs.Public safetyWhen construction works involves public area, it is important to make sure the safety of the public. Consider the following when preparedness for night time work identify the hazards for example construction vehicle movement or too much glare from lighting equipment and plan for vehicular movement to not interrupt peak hours and make sure adequate supervision is provided for such movement.Provide sufficient signage to warn the public and put barriers at a safe distance to keep the p ublic away.Set up a safe walk shipway where it is unavoidable to work near or in public vicinity.Arrange noisy equipments or machinery at farthest point from the public or adopt an engineering control to reduce the hurly burly.When overhead stretch is operating near the public, clear off the area and make sure adequate supervision is in place.Schedule for daily cleaning of the adjacent public road and filling up holes as well as uneven surfaces.Working hours manpower garmentmentEmployers should identify at which construction phase the take aim for night time work is demand. Consider the following when planning for night time work arrange a special team to work at night and allow for shift rotation and predicate workers of the special hazards and risks at night to allow effective adaptation with the work environment.It is also recommended to send workers for health screening to make sure the workers are fit to work at night. Allowing an unfit worker to work at night will enda nger the worker and other worker in the same work area.2.3 Overview of Night-time constructionAccording to the Guidelines for Construction Activities at Night (1999), there is an increasing demand for performing construction of highways and buildings at night, especially in the urban areas to reduce conflict between the public and the stakeholders of the projects. This approach can be beneficial in particular, for reducing employment disruptions and meeting the completion deadlines. However, contractors should consider the increased safety risk at the workplace when conducting any construction activities at night.2.3.1 Planning of construction work at nightWorking during night time by its very nature is dangerous. Workers are exposed to numerous high risk unsafe working conditions at construction site. Common problems that might occur are poor visibility in the working environment, working in a drowsy condition, and communication problems with the day shift. This could contribute to other work related safety and health problems for example drug and alcohol abuse, mental problems, and physiological problems. (Shane J.S., 2012).Therefore, it is very important to plan any works for night time is engaged. Employers need to plan before hand the workforce required, special arrangement for safety provision such as sufficient work area lighting, retro-reflective clothing, flashing lights on equipments or structures and retro-reflective tape at work area surroundings.2.3.2 Factors bear on night time workIn order to decide when to conduct night time work, factors (parameters) touch on night time work must be identified. The following factors were identified (Douglas K.D., 2003) put on the lineIlluminationNuisances productivityCostSafetyRiskNight time construction introduces numerous risks to a construction project. One clear set of examples is driver and worker scare away and reduced visibility, which are factors that could increase safety risks. early(a) major f actors contributing to the risks of night time work are gay factors such as sleep, stress, work, social or domestic issues, and psychological characteristics, such as appetite and safety. Additional factors associated with the risks of night time construction work zones are reduced work space for machinery and equipment movement, inadequate lighting, high speed of traffic during the night, and hanker working hours (12 to 14 hours). (Shane J.S., 2012).Risk management appendageThe best way to address night time construction work-zone risks and hazards is through with(predicate) risk management programs. It is suggested that agencies and contractors begin their risk management processes early and review the risk management program carefully prior to beginning night time work. Risk management is the term used to describe a sequence of analysis and management activities focused on identifying and creating a response to risks and, in the case of night time construction, to project-spe cific risks (Shane J.S., 2012). Various organizations use very similar steps, but pretty different terms, to describe their risk management approach. These are the important risk management steps1. Risk identification.2. Risk opinion/analysis.3. Risk mitigation and planning.4. Risk tryst.5. Risk monitoring and control.Risk identification is the process of determining which risks might affect the project and documenting their characteristics using tools such as brainstorming and checklists.Risk assessment/analysis involves the quantitative or qualitative analysis that assesses impact and probability of risk.Risk mitigation and planning involves analyzing risk response options (acceptance, avoidance, mitigation, or transference) and deciding how to approach and plan risk management activities.Risk allocation involves placing responsibility for a risk on a specific party or parties typically through a contract. The fundamental tenets of risk allocation include allocating risks to th e party that is best able to manage them, allocating risks in alignment with project goals, and allocating risks to promote team alignment with customer-oriented performance goals.Risk monitoring and control is the capture, analysis, and account of project performance, usually as compared to the risk management plan. Risk monitoring and control assists in tracking and resolution.Types of RiskThe first step in an effective risk management program is to identify affirmable risks. Specific concerns related to night time work zones include poor visibility and work quality, staffing issues, outcaste noise and glare, settled worker and driver alertness, impaired drivers, higher vehicle speeds, increased labour costs, materials and traffic control, and problems in logistics and supervision. These risks are categorized broadly as safety, cost/production and schedule, quality, organizational relationships, technical, construction, economic, and environmental.IlluminationNight time const ruction lighting arrangements have an impact on project safety, quality, cost, and productivity. One of the main reasons illumination levels have a strong impact on the other aspects of night time construction is the fact that light influences human performance and alertness.Recommended lighting levelA major problem with night time work-zone lighting arrangements is the insufficiency of the lighting provided to perform the construction or maintenance labor. The level of lighting need for specific construction activities depends on factors related to the humans performing the activities, as well as factors relating to the task at hand and the environment in which it takes place.For example, optical ability is a human factor that is cognize to vary among workers. Therefore, lighting standards assume reasonable visual abilities that are considered to be normal, while giving some allowance for variations among individuals. This assumption allows for visual standards to be based mainl y on the visual requirements of the specific tasks construction activities required (Shane J.S., 2012).Task DependencyVisual StandardRequired AccuracyThe higher the precision required in a task, the higher the level of illumination needed.Background ReflectionThe ability to visualize an object glass or a target depends on the contrast between that object and the background. Highly reflective backgrounds decrease the visibility of the target or object.Relative SpeedThe relative speed of the object/target or its observer is another(prenominal) factor directly affecting the level of lighting needed for the construction task. express moving objects or targets necessitate higher levels of illumination.Objective SpeedThe size of the target observed in construction tasks has an impact on the needed level of illumination for the task. The smaller the object, the higher the level of lighting needed.Seeing distanceThe distance between the observer and the target in each task is another deter mining factor in setting illumination levels. Larger distances necessitate higher levels of illumination.Table 2.1 Task-dependent visual standardsSources A Guidebook for Nighttime Construction Impacts on Safety, Quality, and Productivity.NuisancesSoundSound is energy in effect as a pressure wave through the air produced by a vibrating body. A atomic number 105 (dB) is the basic sound level unit it denotes a ratio of intensity to a reference sound. more or less sounds that humans are capable of hearing have a decibel range of 0 to 140. naught dB, by international agreement, corresponds to an air pressure level of 20 micro-Pascals (in other words, the agreed-upon threshold of hearing). A susurration is about 30 dB, conversational speech is about 60 dB, and 130 dB is the threshold of physical pain. Humans sense the intensity difference of one sound from another. A three-decibel change in noise level is a barely noticeable difference, while a 10-dB change is perceived subjectively a s a doubling/halving in loudness (Shane J.S., 2012).NoiseNoise can seriously harm human health and interfere with peoples daily activities at school, at work, at home and during leisure time.

However, minor cosmetic damages can occur at lower vibration levels and, in the case of old, fragile, or historical buildings, a danger of significant structural damage ever exists.DustDuring the night, many households leave their windows open to take advantage of the cool night air. With urban night time construction projects being very close to peoples living space, dust can be a problem.Night time construction dust problems are accentuated by the lighting, which makes the particulate matter very visible. transient dust may be generated by construction operations, and the contract specifications should require that the contractor prepare a dust control plan. In many cases, dust control is not a problem that is restrict to night time activities therefore, air quality or dust control plans should be for all hours of the day or night (Shane J.S., 2012).
