MAY Blog: Asbestos and California regulations

Why is Asbestos hazardous?

Asbestos is an effective insulator and fire retardant, and it can be used in cloth, paper, cement, plastic, and other materials to make them stronger. But when asbestos dust and particles are inhaled or ingested, mineral fibers can become permanently trapped in the body.

Over decades, trapped asbestos fibers can cause inflammation, scarring, and eventually genetic damage. A rare and aggressive cancer called mesothelioma is almost exclusively caused by asbestos exposure. Asbestos also causes other forms of cancer as well as progressive lung disease.

Asbestos and California regulations

Any renovation or rebuild on every house-made before 1978 is required to perform Asbestos testing and if test results prove positive, abatement procedures are necessary.

From 1928 to 1977, asbestos was found in just about all building materials. This also happens to be the period of time California was experiencing its fastest period of growth, which means a large number of structures are affected by this material. Breaking it apart implies a risk of exposure to a material that aggressively attached itself to living tissue due to its physical structure.

By California Law

By California law, construction contractors are prohibited from providing asbestos testing or abatement. In order to avoid conflict of interest and all clearance tests, anyone with a proprietary interest in the site is also prohibited. This is why you need a reputable, licensed environmental company to perform these services. A third-party company does testing, the California asbestos laws have been put into place to protect you and ensure the environment is kept safe from toxic contaminants.

Taking proper steps in identifying and safely removing the existing contamination in your property will ensure the health and safety of the workers at the job site and the occupants of the property in the long run.
