Danger construction sites

One of the major sources of water pollution in East Africa is human waste. The effluents from untreated mimicipal sewers pose great danger to the conservation of a sustainable ecology in and around Lake Victoria. Municipal sewage contains both faeces and urine that are sources of phosphorus. Therefore let us make two assumptions that will enable us calculate the phosphorus contributions from these sources. Let us assume that each person produces 25-50 kg/yr of faeces which contain 0.18 kg P second, assume that each adult produces about 400 liters of urine per year, depending on liquid consumption, and contains 0.40 kg P. This is because municipal and industrial wastewater treatment plants are known to be the major point sources of phosphorus in urban areas." Waste disposal sites, construction sites, fertilizers and farmyards also make substantial contribution to the total phosphorus load. However, all these have not been adequately evaluated. Given the number of sewered and unsewered municipalities and their populations in Table 2, one is able to calculate the amount of phosphorus produced. 

Because of the dangerous and difficult aspects of obtaining high-level radioactive materials from a nuclear facility, there is a greater chance that the radioactive materials used in a dirty bomb would come from low-level radioactive sources. Low-level radioactive sources are found in hospitals, on construction sites, and at food irradiation plants. The sources in these areas are used to diagnose and treat illnesses, sterilize equipment, inspect welding seams, and irradiate food to kill harmful microbes. 

Although the last question has already been partly answered for us by the fact that we keep appearing in the list of the UK s most dangerous industries, it, and these other questions, will be explored as construction site safety is unpacked within this book. 

The more we reiterate accidents and statistics, even in the negative formats of x hours worked without. .., the more we support the understanding that this is inevitably a dangerous industry, and one in which accidents are just a familiar characteristic of the construction site environment. We could instead do worse than recognise the roots of occupational accidents as a direct result of our work process and practices, rather than inevitable consequences, and therefore start to challenge the way we do things from new perspectives. That we so readily talk about accidents and not safety also helps us understand safety a little better - it is paradoxical, much more easily identified and understood by its absence than its presence, and accidents are the ultimate manifestation of unsafety in practice. 

Within the UK, legislation forms the foundations of many of the management systems and practices found on UK construction sites. Historically, this legislation was focused on danger, security... 

The temporary nature of construction sites makes them one of the most dangerous places to work. These regulations are made under the Health and Safety at Work Act 1974 and are designed specifically to promote safety at work in the construction industry. Construction work is defined as any building or civil engineering work, including construction, assembly, alterations, conversions, repairs, upkeep, maintenance or dismantling of a structure. 

Temporary electrical supplies provided on construction sites can save many man hours of labour by providing the energy required for fixed and portable tools and lighting which speeds up the completion of a project. However, construction sites are dangerous places and the temporary electrical supply which is installed... 

Fire is a real threat at construction sites. Storage and use of flammable liquids increases the threat substantially. Respect for, and proper use and care of dangerous liquids is critical to a safe jobsite. 

Jobsite injuries and illnesses are nothing new. Let s face it, construction sites can be dangerous places. No one goes to work expecting to get hurt on the job, but as much as your company works to prevent it, employees may still become ill or be injured or even killed while at work. 

Ideally the jobsite would be hazard-free. However, working in and around construction sites is dangerous business. The good news is an employer has many ways to control those hazards. One way is to use safety signs, tags, signals, and barricades. 

Combustible materials are a fire hazard at any construction site. Tobacco products, portable heating equipment, small engine equipment, and welding equipment pose the greatest danger. 

Although covered very little in Part 1926, chain saws can be one of the most dangerous power tools at a construction site. They are often used during site clearing operations. If yoru employees use chain saws, you are required to instruct them on their safe use and to recognize and avoid unsafe conditions. Be srue to follow the written operating, adjustment, and maintenance instructions, as well as safety precautions, provided by the manufactruer of your chain saw(s). 

This subpart details the signs required when hazards are present and the notifications required when an employee is nearthat hazard. There are six main signs danger, caution, exit, safety instruction, directional, and traffic signs, that are used on a construction site. The subpart also states what color each sign must be and the size requirements for every sign. 

The largest element here seems to be the feeling of personal control. Those who believe themselves knowledgeable about and in control of a dangerous situation, even where the magnitude of the consequences is potentially great, show little fear or concern about it. This also applies to attitudes towards the safety of others. Thus construction site supervisors may consider that the site hazards are under the control of skilled craftsmen and not personally concern themselves with them, even when they see that...
