SYNOPSIS ASBESTOS STANDARD - CONSTRUCTION OSHA 1926.58 DOW-2478 STOUO8W03 SCOPE: This standard applies to all construction work, e.g., work for construction, alteration, and/or repair, including painting and decorating. It includes 1) demolition or salvage; 2) removal or encapsulation of materials containing asbestos; 3) maintenance; 4) installation of products containing asbestos; 5) spill/emergencv~cleanup; 6) transportation, disposal, storage or containment of asbestos. (Includes everything but chlorine plant operations.) EFFECTIVE DATE; July 21, 1936 COMPLIANCE DATE: January 16, 1987 for all sections. PERMISSIBLE EXPOSURE LIMIT (PEL): .2 fibers/cc of air DEFINITIONS:__ ACTION LEVEL - .1 fibers/cc of air COMPETENT PERSON - One who is capable of identifying asbestos hazards in the workplace and who has the authority to take prompt corrective measures to eliminate them. (See Standard for duties). FIBER - Means a particulate form of asbestos, treipolite, anthophyllite, or actlnolite, 5 micrometers or longer, with length-to-diameter ratio of 3 to 1 or greater. REQUIREMENTS: A. Regulated Areas - Must be established when concentrations exceed .2 fibers/cc of air as an 8-hour TWA 's' 1. ^ 2. -- 3. Demarcate to minimize number of people exposed. Access limited to authorized persons. Protective clothing and a respirator must be worn. PROHIBITED ACTIVITIES - Employees shall not eat, drink, smoke, chew ^tobacco or gum, or apply cosmetics.

T. Whenever feasible, establish negative pressure enclosures.. 2. Designate a competent person to perform or supervise specific duties; e.g. setting up and maintaining enclosure, employee exposure monitoring, training of employees, ensuring use of proper protective equipment, ensuring that employees use hygiene facilities (clean and dirty changeroom, lunchroom, 1 etc.) and follow decontamination procedures. t 3. Assure the competent person is trained in all aspects of '\> asbestos abatement, etc. (EPA Asbestos Training Center course or equivalent.) C. Exposure Monitoring - Representative monitoring for employees engaged in similar work is allowed. 1. Initial Monitoring - required at the beginning of 'each job to accurately determine employee's 3-hour TWA exposure. Exceptions, monitoring not required when n a. Objective data shows that the product or material cannot release airborne fibers which would exceed the action level, b. Previous monitoring of each job which is similar has been done using validated methods. I Periodic Monitoring - Daily when exposures are greater than .2 fibers/cc air. If exposures are less than .1 fibers/cc air as 3-hour TWA or if personnel are wearing supplied air, no monitoring is required. 3. Method of Monitoring - See Appendix A a. Personal samples (See Appendix A for collection procedures.) b. Analytical (OSHA Reference Method, ORM, or equivalent) 4. Employee Notification - As soon as possible, either in writing or by posting.
