A spray gun is to be used for the operation. The sewer chamber is accessed via a manhole cover at ground level in the middle of a field.
The operation is classified as confined space operation. Health and…
The levels of oxygen in confined spaces can be depleted when there is reaction between some soils and oxygen in the atmosphere; or release of gas such as carbon dioxide that can displace ambient air. Poisonous gases, fumes or vapours can built up in the sewer; enter from connecting pipes; or leak from other areas. Residues left on surface of walls can give off gas, fume, or vapour. Scraping before painting can give rise to particulates that can contaminate the ambient air. Spray painting can give rise to volatile organic compounds depending on the composition of the paint. Volatile organic compounds can have adverse health effects including cancer. The person conducting the operation is at major risk for adverse effects described above. Since the sewer is located below a field where cattle and sheep graze, an open sewer could be a fall hazard for these animals.
The control system for this operation includes barricades and procedures for confined space work. According to the Management of Health and Safety at Work Regulations 1999 hazards must be identified; risks assessed and precautions determined. According to the Confined Spaces Regulations 1997 presence of risks of serious injury as in the operation requires following a safe system of work, and putting in place adequate emergency measures before the start of work. The safe system of work is based on the operation described above. A supervisor should be given responsibility for ensuring that necessary precautions are observed for checking the safety at each stage and being present when the work is in execution. The operator must have sufficient experience in conducting painting work in confined spaces. A determination has to be made if there is the need to isolate the sewer, and it must be checked if the isolation is effective. Before entry cleaning is required to determine whether fumes do not develop from residues while work is ...

Could the spraying be done by a robot, perhaps? These kinds of options must be considered in the first place before putting any human lives in jeopardy. It is the employer’s responsibility to ensure that all the safety guidelines are met before anything being done underground.
There are two main types of harm that could occur from this operation. Firstly, the sewer chamber must be accessed via a manhole and stepladder. Falling off this stepladder into the chamber could cause severe physical damage or even death. Additionally, as the fumes are toxic and can cause drowsiness, these could cause injury also.
The field is one mile away from the main road. Considering the above scenario it is expected that the people who may get affected from the harmful spray are: The personnel assigned the task to spray the sealant into the subterranean chamber. The farmer under whose field the chamber is located.
Ventilation has basically been adopted as a hygiene necessity of fulfilling the basic criteria of living in a safe- to- breath- in environment. The acronym HVAC is a sub discipline of mechanical engineering and it stands for Hearing, ventilation and Air Conditioning.The basic purpose of ventilation is to preserve the quality of air (Dr.Sam C.M.
hildren (Reg 19). These regulations are specific to health and safety issues, problems, and how to deal with them. CDM regulations 2007, provide for a much wider range of regulation in a building construction project, and are, as such, a superset of the MHSWR, 1999
Protective equipment such as gas masks or particulate respirators can be used by the workers to protect them from hazards by filtering gasses, chemicals released by the sealant other airborne particulates. The workers should also be provided with a Hazmat suit which is an impermeable garment covering the whole body for protection from the chemicals.
It also offers information on directions on how to meet specified obligations. Regulations are lawfully enforceable. The codes of practice offer provide support on how to attain required standards of health and safety relating to an
The philosophy of healthcare generally entails the study of processes, ethics and people who constitute health maintenance among human beings (Maruish, 2000). On the other hand, the principles of wellness generally entail physical health care,
