Asbestos surveys, on-site air clearances and safety/exposure assessments

Notice to California State Residents

There are many laws and regulations that vary by state and city associated with asbestos removal in residential and commercial buildings. Never remove a suspected or confirmed asbestos-containing material without consulting a licensed asbestos removal professional who is familiar with the regulations applicable in your area.

Asbestos Exposure

Exposure to airborne asbestos can cause adverse health effects to the affected person. Continued exposure can increase the amount of asbestos fibers that remain in the lungs. Fibers embedded in lung tissue over time may cause serious lung diseases including: asbestosis, lung cancer, or mesothelioma. Tobacco smokers who have been exposed to asbestos have a “far greater-than-additive” risk for lung cancer than do non-smokers who have been exposed, meaning the risk is greater than the individual risks from asbestos and smoking added together.

Major repairs must be done only by a professional trained in methods for safely handling asbestos removal. Professionals should also do minor repairs since there is always a risk of exposure to fibers when asbestos is disturbed.

Doing minor repairs yourself is not recommended because improper handling of asbestos materials can create a hazard where none previously existed.

Major Health Effects

Asbestosis is a serious, progressive, long-term non-cancer disease of the lungs

Lung cancer is a malignant tumor that invades and obstructs the lung’s air passages. Cigarette smoking greatly increases the likelihood of a person developing lung cancer as the result of asbestos exposure.

Mesothelioma is a rare cancer which may affect the lining of the lings (plura) or the abdominal contents (peritoneum). Most mesotheliomas are caused by exposure to asbestos.

Gastrointestinal and Colorectal Cancers Studies of asbestos workers suggest that asbestos exposure might be associated with gastrointestinal (esophagus and stomach) and colorectal (colon and rectum) cancers. (No definitive link has been proven between Asbestos and non-respiratory cancers, however studies of Asbestos workers suggests a link)

Signs & Symptoms of Asbestos Exposure

  • Shortness of breath (Primary Symptom)
  • Persistent, Productive Cough (expels mucus)
  • Chest pain, or tightness
  • Loss of appetite
  • Dry crackling noise in the lungs when inhaling

Sources of Asbestos Pollution

Many products that are in use today contain asbestos. Asbestos fibers are incredibly strong and have properties that make them resistant to heat. Most of these are materials used in heat and acoustic insulation, fireproofing, roofing and flooring. In 1989, EPA identified the following asbestos product categories. Many of these materials may still be in use.

  • Popcorn Ceiling
  • Drywall Mud
  • Drywall Texture Coating
  • Decorative Sprays
  • Shingles, Siding and roofing felt
  • Floor Tiles and Mastic
  • Roof Coatings
  • Pipe and Furnace Insulation

Asbestos Inspections, Analysis, Surveys

Pre-Demolition asbestos surveys

We identify the location, quantity and condition of all asbestos containing materials within the building and provide a survey and reporting protocols. We perform a complete visual examination and the careful collection of samples and have them analyzed by your local accredited laboratory. If asbestos is present, the inspector provides a written evaluation and report describing its location, extent of damage, and give recommendations for correction or prevention. Remember, never attempt to disturb asbestos on your own. You need a licensed asbestos removal expert.

Hazardous Building Materials

Rarefied Air Environmental can also locate and report the quantities and conditions of other hazardous building materials within a building such as lead-based paints, and other environmental and air quality hazardous materials.

Simple Solutions to Asbestos Pollution

 

  • Use Common Sense
    • Asbestos is used in many household products, and generally will not release asbestos into the air unless disturbed.
  • Do not cut, rip, or sand asbestos-containing materials.
    • Ripping, cutting, or moving the materials can release the asbestos into the air. If the asbestos material is more than slightly damaged, or if you are going to make changes in your home that might disturb it, repair or removal by a professional is needed.
  • Call a professional Asbestos Abatement Contractor
    • Be certain the contractor has the appropriate accreditations, reputation, and equipment to conduct the tests. The Environmental Protection Agency (EPA) recommends sealing the materials if possible, rather than moving them. We can give you referrals to local abatement contractors that are licensed, knowledgeable and do excellent work quickly.

Asbestos Clearance Test

Air clearance testing should be conducted after any abatement activity that disturbs the asbestos. Our consultants will visually inspect the property to confirm that all necessary abatement work has been properly completed and that the space was thoroughly cleaned (i.e. dust-free), collect and analyze Phase Contrast Microscopy (PCM) air samples to ensure the work area is safe for reoccupation. We analyze samples on site for immediate clearance.
