Asbestos is a dangerous carcinogen that needs to be handled by licensed Asbestos Perth professionals. It is regulated as hazardous waste and must be taken, transported, and disposed of by state and federal laws.
All asbestos waste must be wetted down before being placed into a leak-proof container and sealed securely. This process is known as “presenting for storage.”
The EPA’s asbestos rules require anyone who wishes to handle or transport waste containing friable asbestos to do so under a permit. This includes building owners, construction companies, and asbestos abatement contractors. Before commencing work that could disturb asbestos materials, such as a home renovation or demolition project, it is important to consult an experienced asbestos consultant to determine whether any regulated activities are required. Disturbing materials made with asbestos can release asbestos fibers into the air and may lead to health complications such as mesothelioma.
The permit requirements include:
- A written asbestos management plan.
- Air monitoring and clearance.
- Disposal at an approved waste facility.
The asbestos management plan must include the name of the owner and the licensed contractor and the location where the work will take place. The plan must also detail the types of work that will be performed. The hazard level for the waste must also be identified.
Depending on the type of project, the asbestos disposal costs can vary considerably. However, proper asbestos disposal is vital to protect the environment and the health of workers, residents, and visitors.
Anyone who wishes to transport or dispose of special waste, including asbestos, must file an ARTS E-File notification to obtain a permit. A notification must be submitted for each asbestos-related activity, regardless of the number of jobs performed under the same permit.
Any person wishing to conduct Class I asbestos activities, such as removal of ACM or encapsulation, must also have an onsite inspection performed by a certified industrial hygienist. The inspector must verify the asbestos abatement is being completed by a qualified individual and that air monitoring results are clear of asbestos.
Any non-friable asbestos that is not being removed from a structure must be placed in a container that is sealed with plastic six mils or thicker or a metal can with a liner. The liners or containers must be leak-proof and tightly closed. The encapsulated asbestos must also be labeled with “Asbestos Waste Material” or other warning labels authorized by state law or regulation.
Anyone working on asbestos projects must abide by strict safety measures. This includes ensuring that any waste that comes into contact with asbestos is double-bagged and placed in a skip for immediate disposal. This is especially important for overalls, overshoes, and sampling wastes that can carry traces of dangerous material. In addition, any pipes that have been broken and contaminated must be dealt with as hazardous/special waste.
All waste materials containing asbestos must be wetted before double-bagged and sealed in leak-proof containers. These must be plastic bags of a minimum 6-millimeter thickness or cartons, drums, or cans. All containers must also be marked with the word “Asbestos” and have a warning label that states “Breathing Asbestos Hazardous to Your Health.”
Leak-proof containers are essential because asbestos can release deadly fibers into the air when disturbed. Once the waste is packaged, it can be transported from its generation site to a waste storage area. Once the waste is present for transport away from the site of generation, it must be placed in a vehicle and transported to a landfill that is authorized to accept asbestos waste.
The Environmental Protection Agency strictly regulates the disposal of asbestos. Asbestos companies must be EPA-licensed and work only with approved contractors to ensure the proper removal and disposal of the dangerous material. In addition, those who attempt to remove asbestos alone can face serious fines and legal action.
In some instances, asbestos can be recycled. This process converts the material into non-toxic materials such as ceramic and porcelain stoneware tiles, porous single-fired wall tile, silicate glass, and road aggregate. It can also be decomposed through high-temperature incineration and plasma melting techniques. However, the most common method for destroying asbestos is through thermal decomposition. It is then ground down and disposed of as nonhazardous inert minerals. This process needs to be foolproof and requires extensive laboratory testing. However, it is a viable alternative to landfills.
Many local, state, and federal agencies are responsible for establishing regulations involving the handling and disposal of asbestos waste. In general, federal regulations are set by the Environmental Protection Agency, the Occupational Safety and Health Administration, and the county and state Department of Environmental Quality.
During the removal process, a contractor must properly bag and contain asbestos waste to prevent airborne contamination. The contractor must also properly label all containers. Generally, the containers transporting asbestos waste should be 55-gallon metal drums. A contractor must also contact the intended landfill to make sure it can receive the waste and is aware that the waste will be transported there.
The Environmental Protection Agency must approve waste disposal sites to accept asbestos waste. In general, the site must be at least one mile away from a residence or commercial building, be isolated from water sources, have no visible emissions of asbestos dust in the air, and have no industrial uses of chrysotile asbestos (which are limited to manufacturing and fabricating operations).
Before a site will accept asbestos waste, it must verify that the waste is wetted and contained in leak-proof containers. The site must also require the completion of a chain-of-custody form by the waste generator.
Once the waste is at a designated disposal site, it must be contained in a trench that allows soil cover over the waste without disturbing the containers. The site must be ramped to enable a vehicle to back into the area. It must be aligned perpendicular to prevailing winds to reduce wind-driven fiber release during cover placement. A decontamination enclosure system must be installed to permit the removal of contaminated clothing, shoes, and tools. Wet rags must be used to remove protective equipment and damp clothing after each use.
Once the site is prepared to receive asbestos waste, it should be checked by the Environmental Protection Agency regional NESHAPs contact to ensure that the waste contains asbestos and meets all other disposal requirements. The site should also verify that the load has been wetted, double-bagged, and sealed in plastic leak-tight containers.
Asbestos is a dangerous substance that can cause deadly diseases like mesothelioma. It is a toxic waste and is normally disposed of in hazardous landfills that are authorized to receive it. However, recycling options have been proposed to save landfill space and prevent further exposure to asbestos in workers handling the waste.
When asbestos is recycled, it becomes a nonhazardous material that can be reused for various purposes. The most common way of doing this involves thermal decomposition. This involves heating the ACM to temperatures above 1,250 degrees Celsius, which destroys the fibrous structure of the asbestos. This makes various products, including silicate glass, porous single-fired wall tiles, and ceramic bricks. It can also be used as aggregate in roadways (asbestos asphalt) and concrete construction.
Aside from thermal decomposition, other methods of transforming asbestos into nonhazardous materials include microwave thermal treatment and plasma melting. These processes heat the asbestos in a high-temperature environment to break down its fibers and reduce their toxicity. These techniques are more expensive than the traditional method of disposing of asbestos, but they can be more cost-effective on a life-cycle basis.
It is important to remember that when asbestos is recycled, it must still be handled and transported safely. Any asbestos-containing materials not being sent to a landfill must be properly stored and sealed. This is a necessary step to ensure that the waste doesn’t spread or release its fibers into the air. Asbestos must be wet before being stored, and the container should be examined for any leaks that could create a dust cloud.
Storage holds asbestos waste temporarily at the site of generation or another place where it is being stored. It can start immediately after the waste is presented for storage and does not end until it is transported to its final destination.
Disposal refers to the dumping, depositing, or spilling waste containing asbestos onto land or water. This includes any disposal activity that could expose the public to hazardous wastes, and it may involve a contaminated site or any other area of the environment.
