Asbestos Abatement >> California Asbestos Tile Removal Requirements

Identifying hazardous materials before starting work on a project site protects worker health and safety, building occupants, and the financial viability of the project. Doing this up front can help you choose the appropriate inspectors, consultants and contractors and avoid costly change orders or California Asbestos Tile Removal Requirements project delays. 

Before you begin any demolition or renovation project, thoroughly inspect and inventory the California Asbestos Tile Removal Requirements project site for the following items: Appliances: Appliances may contain CFCs, mercury or PCBs. Appliances that contain CFCs or PCBs must be processed by an appliance demanufacturer registered with the DNR. 

Building materials and fixtures that may contain asbestos: All layers of materials, behind walls, ceiling spaces, etc., should be inspected and sampled unless they are assumed to contain asbestos. The following building components may contain asbestos, but this California Asbestos Tile Removal Requirements list is by no means allinclusive: 

Caulking: Used around windows, doors, corrugated roofing and other places where two materials are joined. PCBs have also been found in California Asbestos Tile Removal Requirements caulking materials. Schools and industrial buildings constructed or renovated between 1950 and 1979 are suspected to contain PCB-containing caulk. 

Ceilings: Including acoustical tiles and adhesives, and the materials listed under "Interior and exterior walls” below. All ceiling layers and any spaces above the ceiling where drop ceilings are present should be checked. California Asbestos Tile Removal Requirements Insulation debris may also be lying on top of ceiling tiles. 

Electrical systems: Insulators; spark arrestors and transite panels in electrical boxes; wiring insulation; ducts/conduits (transite pipe); and light fixtures. California Asbestos Tile Removal Requirements  Flooring: All sizes of vinyl floor tile, sheet flooring, and linoleum, and felt paper used under hardwood floors. 

HVAC systems: Duct, pipe, and joint insulation because elbows/joints are often coated with asbestos; fiberglass insulation on the straight runs; forced air dampers; wall, floor and chimney penetrations; lining and mortar; fire brick; fireproofing materials such as transite sheets or heavy paper; California Asbestos Tile Removal Requirements boiler  insulation.

Flexible fabric connectors; packing/gaskets and adhesives; paper backing; mastic/adhesives (floor tile, carpet, etc.); and grout and felt paper under hardwood floors. o Insulation in ceilings and walls: Blown-in, spray-applied, and block.  California Asbestos Tile Removal Requirements Interior and exterior walls.

Wall plaster; joint compound; patches; transite wallboard and siding; fire doors; window putty/glazing/caulking; mortar; asphalt shingles/siding; felt under siding, stucco, textured paint, and other spray-applied materials. 
Paint containing asbestos is rare except California Asbestos Tile Removal Requirements in commercial applications, where it was usually applied as a very thick.

Often silver colored coating or added to textured paints. o Miscellaneous: Appliances California Asbestos Tile Removal Requirements with a heating element, especially older models; fire curtains and blankets; laboratory tabletops; fume hood linings; blackboards; and fire-resistant clothing like gloves, hoods, aprons, etc. 

Plumbing: Pipe wrap, pipe joints, transite counter tops in bathrooms, faucets, packing gaskets, and adhesives. o Roofing: Asphalt shingles; tar-type coatings which are often around vents, chimneys, etc.; transite shingles; roofing felts that are often under a layer of other material; flashings; and mag-block type material found under other California Asbestos Tile Removal Requirements material. 

Check all roof areas and roofing layers. Lighting fixtures/ballasts and bulbs/lamps: Switches for lighting may use mercury relays. Look for any control associated with exterior or automated lighting systems, such as "silent” wall switches. California Asbestos Tile Removal Requirements Several types of light bulbs or lamps contain mercury and must be properly and legitimately recycled or disposed of as hazardous waste. 

These include: o Fluorescent lights: Even the newer lamps with green-colored ends contain mercury. o High intensity discharge: metal halide, high pressure sodium, mercury vapor.  California Asbestos Tile Removal Requirements Neon Meters and switches: Mercury may be found in thermometers, barometers, thermostats, blood pressure devices, and fluorescent and other types of light bulbs. 

Any equipment used for measurement of vacuum, pressure, fluid level, temperature, or flow rate could contain mercury. These California Asbestos Tile Removal Requirements devices are most commonly associated with commercial and industrial equipment systems, including tanks, boilers, furnaces, heaters, electrical systems, water cleaning systems, and systems for the movement or pumping of gas (air) or liquids (water). 

In addition, mercury containing devices are also common in certain agricultural operations such as dairy, and may be present in older model consumer appliances and California Asbestos Tile Removal Requirements residential properties, especially larger multi-unit properties. 

Oil: Used oil in containers or tanks, hydraulic oils in machinery, electrical transformers and capacitors, and elevator shafts. These oils may contain PCBs and may need to be tested to determine if the California Asbestos Tile Removal Requirements oil can be recycled or must be properly disposed of. Paint: Residential and industrial paints may contain lead, solvents or asbestos. 

Some industrial paints may contain PCBs. In addition to the items listed above, be aware of these other site-related concerns: Abandoned wells: Unused and improperly abandoned wells are a significant threat to California Asbestos Tile Removal Requirements groundwater quality. If not properly filled, abandoned wells can directly channel contaminated surface water into the groundwater. 

State law requires that all wells and drill holes be properly filled prior to any demolition or construction work on the California Asbestos Tile Removal Requirements property. Batteries (non-lead-containing): Batteries may be found in smoke detectors, emergency lighting systems, elevator control panels, exit signs, security systems and alarms. 

Batteries should be separated from other wastes and taken to a recycling facility or a business that accepts batteries for recycling. Computers and other electronics: Most electronics are banned from California Asbestos Tile Removal Requirements landfills and must be recycled. 

These can contain hazardous materials such as lead, cadmium, chromium, and mercury and, if not recycled, may be regulated as hazardous waste. Exit signs: Many self-luminous exit signs contain tritium, a radioactive material. California Asbestos Tile Removal Requirements All selfluminous exit signs must have a permanent label that identifies it as containing radioactive material. 

The label will also include the name of the manufacturer, the product model number, the serial number, and the quantity of tritium contained. It is illegal to abandon or dispose of these signs except by sending them to the California Asbestos Tile Removal Requirements manufacturer or to others licensed by the U.S. Nuclear Regulatory Commission. 

Painted concrete: Walls and foundations often contain painted concrete. 
With prior DNR approval, contractors can grind the concrete and use it on-site or nearby under a new building or California Asbestos Tile Removal Requirements road. Smoke detectors: The smoke detectors that contain a small amount of radioactive material will be labeled and should be returned to the manufacturer for disposal. 

Otherwise, smoke detectors may go in the trash. Soil contamination: A qualified environmental consultant can conduct environmental property assessments including California Asbestos Tile Removal Requirements identification of contaminated soil. Spills: In Wisconsin, all spills of hazardous substances that negatively affect.

Threaten to negatively affect public health, welfare or the environment must be immediately reported to the DNR via the Spills Hotline. Tanks: Chemical tanks (underground and above ground) and septic tanks should be assessed, emptied and California Asbestos Tile Removal Requirements decommissioned.
