Asbestos Building Inspector Initial Exam Questions With 100% Verified Solutions

Asbestos Building Inspector Initial Exam Questions With 100% Verified Solutions Buildings covered under NESHAP (and exclusions) - ANSWER Excluded: private homes and apartment buildings with 4 or less units (Except these are covered still in SoCal under SCAQMD) Included: Institutional Buildings (hospitals, schools), commercial buildings (offices, apartment buildings), industrial buildings (warehouses, factories). Removal before reno or demo rule & exceptions - ANSWER All RACM must be removed before demo or reno of a building if the amount of ACM is greater than 160 sqft, 260 lf, or 35 cf Exception: Does not need to be removed if it's Cat I nonfriable ACM (packing, gaskets, asphalt roofing, vinyl - have flexibility and won't become DUST if hit), on a component packed in concrete, not accessible for testing or not discovered before demo, Cat II nonfriable (that are unlikely to become crumbled, or reduced to powder during demo) RACM - ANSWER Regulated asbestos containing material. Friable ACMs (like popcorn ceiling) Category I non-friable materials Category II non-friable materials OSHA Construction Industry Asbestos Standard - ANSWER 29 CFR 1926.1101 (CA is Title 8 CCR Section 1529) Sets the Permissible Exposure Limit (PEL) of 0.1 f/cc and Excursion Limit (EL) of 1.0 f/cc of asbestos in air. Requires: work practices protective suits medical exams recordkeeping air sampling negative air pressure enclosures respiratiors hygiene facilities OSHA Respirator Standard - ANSWER 29 CFR 1910.134 (CA is Title 8 CCR Section 5144) PEL - ANSWER Permissible Exposure Limit: 0.1f/cc of asbestos in air over an 8 hr time weighted average. It's the highest level of fibers in the air allowed by law for a worker to be exposed to. If a work area reaches the PEL, OSHA says must stop until you have: training, RESPIRATORS, protective suits, medical exam, contained the work area, and negative air pressure. EL - ANSWER Excursion Limit: 1.0 f/cc of asbestos in air over a 30 min period of time. It's the highest amount of fibers a worker can be exposed to in any 30 min per of time. Per OSHA if work area reaches EL stop work and limit amount of asbestos dust in air by using more amended water and bagging up the asbestos waste more quickly. OSHA right-to-know - ANSWER 29 CFR 1910.1200 How is asbestos measured? - ANSWER In fibers per cubic centimeter (f/cc) Friable asbestos - ANSWER Asbestos that can be crumbled in your hand. Example is sprayed-on ceiling insulation. Non-friable asbestos - ANSWER Ex: vinyl-asbestos floor tile. But if you saw, drill, strip, or sand the tile it may become friable. Category I non-friable includes roofings, flooring, packings, and gaskets. Category II non-friable includes all other non-friable asbestos materials Bulk Sample - ANSWER To send a piece of material to a lab to see if it's asbestos PLM - ANSWER Polarized Light Microscope/Microscopy. The EPA required method for analyzing bulk materials for asbestos. Uses a light microscope equipped with polarizing filters. The identification of asbestos fiber bundles is determined by the visual properties displayed. The limit of detection by PLM is about 1% BY AREA. Samples containing lower levels are not reliably detected by this technique. How many types of asbestos fibers are there? - ANSWER 6 What are the three most common kinds of asbestos fibers? - ANSWER Chrysotile, amosite, and crocidolite Chrysotile - ANSWER Serpentine. Counts for 80-95% of all asbestos in buildings Amosite - ANSWER Amphibole. Less than 15% of all asbestos found in buildings. Does not soak up water easily. Crocidolite - ANSWER Amphibole. Less than 5% of all asbestos found in building materials. Three federal agencies that deal with asbestos: - ANSWER 1. EPA - protects against pollution. Under it is: AHERA (the EPA's asbestos in schools reg), ASHARA (the EPA reg that updates AHERA), & NESHAP (The EPA reg that covers asbestos as an air pollution problem) 2. OSHA 3. NIOSH (National Institute for Occupational Safety and Health) NIOSH - ANSWER National institute for occupational safety and health. Researches worker safety and health, and reports its findings to OSHA. Makes recommendations to OSHA and approves respirators. When do you need a medical exam? - ANSWER Per OSHA, if you wear a negative pressure respirator, are exposed to at or above the PEL for 30
