1. Asbestos is the generic term for a group of naturally occurring, fibrous minerals with high tensile strength, flexibility, and resistance to heat, chemicals, and electricity True False 2. In the construction industry, asbestos is found in installed products such as sprayed-on fireproofing, pipe insulation, floor tiles, cement pipe and sheet, roofing felts and shingles, ceiling tiles, fire-resistant drywall, drywall joint compounds, and acoustical products. True False 3. Exposure to asbestos can cause disabling or fatal diseases such as asbestosis, an emphysema-like condition; lung cancer; mesothelioma, a cancerous tumor that spreads rapidly in the cells of membranes covering the lungs and body organs; and gastrointestinal cancer. True False 4. The initial exposure assessment must be based on the following criteria: Results of employee exposure monitoring, unless a negative exposure assessment has been made Observations, information, or calculations indicating employee exposure to asbestos, including any previous monitoring a & b None of the above 5. A regulated area is a marked-off site where employees work with asbestos, including any adjoining areas where debris and waste from asbestos work accumulates or where airborne concentrations of asbestos exceed, or can possibly exceed, the PEL. True False 6. An employer performing work in a regulated area must inform other employers’ onsite of the following: Nature of the work, Regulated area requirements, and Measures taken to protect onsite employees. All of the above 7. To remove asbestos-containing roofing materials, employers must ensure that workers do the following: Remove them intact if feasible Use wet methods when intact removal is infeasible Mist cutting machines continuously during use, unless the competent person determines misting to be unsafe All of the above 8. Class I asbestos work is the most potentially hazardous class of asbestos jobs. This work involves the removal of asbestos-containing thermal system insulation and sprayed-on or troweled-on surfacing materials. True False 9. On all construction sites with asbestos operations, employers must designate a competent person-one who can identify asbestos hazards in the workplace and has the authority to correct them. True False 10. Employers must determine employee exposure measurements from breathing zone air samples representing the 8-hour TWA and 30-minute short-term exposures for each employee. True False 11. What does PEL stand for? Permissible exposure limit Permeable energy limit Permission excel limited None of the above 12. For any specific asbestos job that trained employees perform, employers may show that exposures will be below the PELs. True False 13. For Class I and II jobs, employers must conduct monitoring daily that is representative of each employee working in a regulated area, unless you have produced a negative exposure assessment for the entire operation and nothing has changed. True False 14. Changes in processes, control equipment, personnel, or work practices that could result in new or additional exposures above the 8-hour TWA PEL or STEL require additional monitoring regardless of a previous negative exposure assessment for a specific job. True False 15. Employers must make medical exams and consultations available to employees as follows: I. Prior to employee assignment to an area where negative- pressure respirators are worn; II. Within 10 working days after the 30th day of combined engagement in Class I, II, and III work and exposure at or above a PEL, and at least annually thereafter III. When an examining physician suggests them more frequently. True False 16. What does NIOSH stand for? National Institute for Occupational Safety and Health National Institute for Online Survey National Institute for Operational Safety and Health None of the above 17. Employers must supply a respirator to all persons entering regulated areas. Employees must not eat, drink, smoke, chew (tobacco or gum), or apply cosmetics in regulated areas.
True False 18. The contractor creating or controlling the source of asbestos contamination must abate the hazards. All employers with employees working near regulated areas, must daily assess the enclosure’s integrity or the effectiveness of control methods to prevent airborne asbestos from migrating. True False 19. A designated competent person must supervise all Class I work, including installing and operating the control system. The competent person must inspect onsite at least once during each work shift and upon employee request. True False 20. Employers must ensure the following for all Class I jobs: I. Isolating heating, ventilating, and air-conditioning (HVAC) systems in regulated areas by sealing with a double layer of 6-mil plastic or the equivalent. II. Placing impermeable drop cloths on surfaces beneath all removal activity. III. Covering and securing all objects within the regulated area with impermeable drop cloths or plastic sheeting IV. Ventilating the regulated area to move the contaminated air away from the employee-breathing zone and toward a HEPA filtration or collection device for jobs without a negative exposure assessment or where exposure monitoring shows the PEL is exceeded.
