Demolition in hazardous environments such as nuclear power plants, industrial smokestacks, and chemical accident sites can be both a risky and complicated process. One of the safest methods developed to-date is the use of remote controlled robotic machinery. Robotic controlled demolition equipment allows operators to maintain a safe distance usually within a protected environment while demolishing the hazardous structure. This allows for a surgical demolition and removal of structures without contamination or damage to the surrounding environment.
Nuclear power plants are a particular challenge. All nuclear power plants have a finite lifespan. When a nuclear power plant must be shut down and cease operations it needs to be decommissioned. Decommissioning a nuclear plant involves safely removing or permanently encasing any material that is radioactive. According to the Nuclear Regulatory Commission (NCR) regulations decommissioning must be completed within 60 years of the plant terminating operations. The NRC has strict rules governing nuclear power plant decommissioning, involving cleanup of contaminated systems and structures and removal of the radioactive spent fuel. These requirements protect workers and the public during and after the decommissioning process.
If demolition of the facility is required in order to properly decommission the structure, robotic equipment must be capable of demolishing, removing, sorting, and containerizing radioactive waste so that it can be safely deactivated. To perform these tasks the equipment must be highly mobile and able to work in confined spaces with a variety of attachments depending on the stage of demolition. Equipment operators will need precise remote controls used in conjunction with video cameras to efficiently demolish and remove radioactive structures.
Some types of nuclear plant decommissioning involves maintaining and monitoring a nuclear plant or permanently encasing radioactive contaminants until the radioactivity decays and the plant is then safe to dismantle and demolish.
In the case of structures contaminated by chemical spills or hazardous waste, demolition involves a safety risk due to the release of toxins to the environment in the form of dust, smoke, or vapors. Robotic equipment allows for work in contaminated areas without endangering the health and safety of construction workers. For example, demolition in confined areas containing asbestos material which was often used as a form of insulation in older buildings is the perfect application for robotic demolition equipment. Demolition of structures for safety reasons after chemical spills or industrial accidents is another example where robotic equipment can be used to break, cut, crush, drill, scarify, shear or grapple material at the contaminated site without harm to the environment, workers or public health.
Robotic controlled equipment has both the versatility and proven capability to work in any industry where hazardous material or contaminated by-products need to be considered in the demolition process.

Did you know that Radon (a colorless & odorless gas that sometimes accumulates in basements or other confined areas in the house) can cause lung cancer? In fact, United States Environmental Protection Agency states that after cigarettes, Radon gas is the most recurring cause of lung cancer in United States. This means, you can be exposed to the risk of developing lung cancer while living in a particular building, without even knowing it. The reason for all this information is not to scare people, but to highlight the importance of knowing (and doing something) about the probable environmental hazards in your residential or commercial properties. It also means that you must take environmental hazards into consideration when buying a property.
Environmental issues are becoming a much bigger concern with the passage of time, as new discoveries and researches continue to reveal, how a seemingly harmless element can cause serious damages. Even though, most of these hazards can be taken care of once they are identified, but it can be a costly procedure. Therefore, this information must be a part of your buying decision, especially when you are negotiating on price. In some states, laws are being introduced, asking property sellers to disclose such information at the time of sale, but even if such laws are not practiced, it is a buyer’s right to be sure of the nonexistence of such environmental vulnerabilities.
Asbestos:
Asbestos is a type of fiber which was used in a number of products in the past. People, who are exposed to high level of asbestos, can develop mesothelioma, lung cancer or asbestosis (due to the inhaling of asbestos particles). Although, Asbestos is not used in product manufacturing anymore, it is still found in older products and homes. Therefore, you should consider hiring some Asbestos professional, if you are going to buy an old home.
Radon Gas:
As stated above, Radon gas is an odorless gas that can cause serious breathing problems. There are test kits in the market to examine the air quality and radon level in the living areas. There are various ways to remove or reduce radon accumulation. For example, you can make use of ventilating fans. Note that radon is mostly a problem in confined areas like basements and high radon levels are not likely in good airy rooms, with windows and proper ventilation.
Lead:
Lead particles can be ingested that results in damage to the bones, blood or nervous system (especially in the children). It can dissolve into the drinking water, making it hazardous to consume. Use of lead in any form is prohibited especially in the homes or products that deal with children.
The lethal dust of asbestos despite being banned from residential and commercial buildings, however still inflicts deadly diseases which can only be restricted through strict implementation of the law. To save the public from asbestos exposure, legislation banning the import of this deadly asbestos and banning the use of the rest of the asbestos products is the imminent need of the hour. The construction companies and their suppliers should through additional legislation be prevented to use this dangerous material which gives death to living beings. To prevent this health menace it’s extremely important to remove existing asbestos and demolish its entire construction works.
Its not that the dangers posed by asbestos and its products to human health have gone unnoticed. As far back as in the year 1970 the asbestos industry voluntarily banned the import of raw blue asbestos and from 1980 a similar voluntary ban was imposed on brown asbestos. Finally, in the year 1986, the United Kingdom Government legally prohibited the use, supply and import of the blue and brown asbestos, including asbestos spraying and fitting of asbestos filling. Different laws such as the Health and Safety at Work Act 1974, The Control of Pollution Act 1974, The Asbestos Products (Safety) Regulations, 1985, The Consumer Safety Act 1978, The Control of Pollution (Special Waste) Regulations, 1980, The Asbestos (Licensing) Regulations, 1983, The Control of Asbestos at Work Regulations 1987, as amended in 1992, The Collection and Disposal of Waste Regulations, 1988, The Water Act 1989, The Trade Effluents (Prescribed Processes and Substances) Regulations, 1989, The Control of Asbestos in Air Regulations, 1990, and The Asbestos (Prohibitions) Regulations, 1992, have already been enacted by Parliament.
The laws which directly regulate work with asbestos are contained in the Asbestos (Licensing) Regulations, 1983, the Control of Asbestos at Work Regulations 1987 as amended in 1992, and the Asbestos (Prohibitions) Regulations, 1992. The Institute of Occupational Medicine runs the national quality control scheme to monitor the ability of laboratories to count the fibres accurately. Initially, the laboratories only counted the number of fibres present on membrane filters and identified the type of asbestos present in large samples. However after 1992 they also got approved to conduct air sampling in accordance with HSE method MDHS 39/3. At this time there are over 100 laboratories certified by National Accreditation of Measurement and Sampling for asbestos appraisal and 12 of which are approved for asbestos sampling. Samples which are drawn four times a year are sent to the laboratories which are categorized into 1, 2 and 3 groups. The group 3 is considered unacceptable. The laboratories send their analysis back to RICE.
The aim is to limit the exposure to asbestos to a minimum which is below the control limits of 0.01 respirable fibres/ml of air, and apply to people working with asbestos and not to other employees or the public. Even at this level there exist 10,000 fibres per cubic metre in the air. Since one human being requires one cubic metre of air to inhale per hour there is enormous risk involved. As per research in US, any person breathing this level of asbestos for ten years would have a 3 out of 1000 risk to develop asbestos cancer.
In installation and infrastructure its application gets wider. Either its turnkey projects or cutting edge erection welding is unavoidable and a must requirement. Without the basic function of welding even nation building becomes next to impossible.
There are few basic operations of building. They are civil, electric. They are marine, automobile, mechanical, and aeronautical. You name it and they have it. Welding has both positive and negative features too as all other fields have. In this welding field the positive feature is the beneficiary angle and the negative factor is the angle of performer.
Welders are open to professional hazards. Welding for long time and virtue of there exposure the welders have many process. A variety of ailments they are affiliated with. There around 4 lacks people employed for welding. After a scientific research a studies have reveled the fact that these workers are at a serious risk of respiratory, reproductive, neurological and digestive problems in a published report it is found that there are huge respiratory dieses like bronchitis airways irritation and many more in welders in large number.
Damage the nervous system and lung cancer are dieses causes by welding fumes. These fumes create and contain nickel, chromium, manganese. Hexavalent and nickel chromium are defined as occupational potential carcinogens. Al the more a continuous and cronic exposure to manganese may cause the welder ailments of parkison dieses.
There are two complimentary research classified. They are a epidemiological studies of continuation and it offers a thorough understanding about the problem and root cause of many diseases like lung cancer, immune suppression, skin damage, reproductive disorder the important bio chemical examine by the toxicology investigation to the welding fumes , at the molecular level in lab experiments. N a recent studies it is reveled a fact sheet presented by a welding hazard facts which provides information about disease caused by welding, soldering, brazing, metal cutting.
As per a report a welding smoke could be a mixture of very fine particles and gases. Chromium, nickel, manganese, arsenic, asbestos, can be life threatening and extremely toxic mostly the fumes created are derived from the base material or the filler substance, coating and paints on metal itself which in turn covers the electrodes, shielding gases, chemical reaction from arc and also ultra violet light and heat consumable, contaminants and processes.
There are many other welding dieses. Smoking makes a difference a welder who smokes may have a higher chance of having there health damage then those who avoid or away from smoking. There are long and short term reaction includes chills, normal fever, thirst, metal fume fever, muscle ace, chest coreness, fatigue, wheezing etc
Smoke coming out of welding smoke irritates, eyes, nose, chest and repertory track. Cadmium which comes out of welding fumes can be fatal. Welders risk there life and get into welding.
