DISCLAIMER: Asbestos fibers are acknowledged carcinogens by the Air Quality Management District, EPA and several State of California governing bodies. Inhalation of microscopic asbestos fibers may result in disease of the lungs including asbestosis, lung cancer, and mesothelioma. Precautions in this mini guide are not to be your complete solution as rules and regulations change with time. Please avoid creating and breathing airborne asbestos particles from materials known or suspected to contain asbestos. This website does not address all of the safety concerns. It is important to hire appropriate safety and health firms/individuals to assess all hazards and risks associated with asbestos.
Demolition contractor SoCal Removal recommends structure demolition Asbestos-Containing Material (ACM) surveys and assessments be conducted in general accordance of ASTM E2356 Standard Practice for Comprehensive Building Asbestos Surveys. ASTM E2356 meets the
applicable requirements of current Environmental Protection Agency (EPA) National Emission
Standards for Hazardous Air Pollutants (NESHAP) Standard 40 CFR 61, Subpart M (Asbestos), EPA
Asbestos Hazard Emergency Response Act (AHERA) Standard 40 CFR 763, Subpart E, and
Occupational Safety and Health Administration (OSHA) asbestos survey and/or sampling regulations.
State licensed Asbestos Consultants collect bulk asbestos samples. The materials sampled are placed carefully inside individual sealed plastic containers, each with a unique sample identification number. Information as to the location, quantity, and condition of the suspect ACM must be documented on site map field sampling forms. Sampling equipment to be cleaned between samples to prevent cross contamination. Sampling of building materials or debris must be gathered in a manner to minimize the potential for release of asbestos fibers.
Before sampling, the consultant or industrial hygienist must conduct a preliminary inspection to visually identify and quantify suspect
ACMs. Suspect materials should be divided into “homogeneous areas,” which are building materials that
were determined by the inspector to be homogeneous based on their color, texture, and age. A
homogeneous area consists of a suspect ACM that is uniform in texture and appearance, is believed
to have been installed at one time, and is not likely to consist of more than one type or formulation of
material. This preliminary information was utilized to form a sampling strategy that would allow for a
representative number of samples to be randomly collected from each observed suspect material (i.e.,
An Asbestos-Containing Material is a commercial asbestos product containing more than 1%
asbestos. ACMs must be disposed as hazardous waste. Note: Federal OSHA and Cal-OSHA control
materials containing any amount of asbestos. An Asbestos-Containing Construction Material (ACCM)
is a California term for a manufactured construction material containing greater than 0.1% (one tenth
of one percent) of asbestos. South Coast Air Quality Management District overseas jurisdiction at the County of Orange, Los Angeles, San Bernardino and Riverside Counties.
Upon completion of the survey, chain-of-custody forms are filled out and the samples sent or personally delivered
under chain of custody manifest to an accredited laboratory testing facility such as LA Testing, Test America for bulk sampling analysis using
polarized light microscopy (PLM), in accordance with the U.S. EPA’s “Method of Determination of
Asbestos in Bulk Samples,” EPA/600/R-93/116. The laboratory used during this project is accredited
by the National Voluntary Laboratory Accreditation Program (NVLAP) for asbestos analysis and or the
California Environmental Laboratory Accreditation Program (ELAP).
