Two hours exposure at 150 ppm Permission must be requested from ACGIH to reproduce the TLVs and BEIs. Since 1970, OSHA promulgated complete 6(b) standards including new PELs for 16 agents, and standards without PELs for 13 carcinogens. Legionnaire's Disease, see OSHA's Safety and Health Topics Page for updated information. Since Em is less than unity (1), the exposure combination is within acceptable limits. During growing seasons, outdoor fungus-spore levels can range from 1,000 to 100,000 cfu/m3 of air. Therefore, ventilation surveys should be initially conducted. The ACGIH Bioaerosols Committee's guidelines for assessing the role of bioaerosols. Includes the use of natural, dilution, local exhaust, or increased ventilation efficiency. NIOSH found that 5% of its investigations of indoor air quality involved some type of microbiological contamination. See also 1910.1043 for cotton dust limits applicable to other sectors. New York: ASHRAE. 5, International Indoor . An employee's exposure to a substance listed in Table Z-2 shall not exceed at any time during an 8-hour shift the acceptable ceiling concentration limit given for the substance in the table, except for a time period, and up to a concentration not exceeding the maximum duration and concentration allowed in the column under "acceptable maximum peak above the acceptable ceiling concentration for an 8-hour shift.". Table Z-2. Employee complaints can be due to two types of building problems: sick or tight building syndrome and building related illnesses. Use a portable infrared spectrometer to evaluate a wide variety of potential air contaminants including acetic acid, ammonia, carbon dioxide, carbon monoxide, nitric oxide, nitrogen dioxide, sulfur dioxide, and a number of volatile organic compounds. An employee's exposure to any substance in Table Z-1, the exposure limit of which is not preceded by a "C", shall not exceed the 8-hour Time Weighted Average given for that substance in any 8-hour work shift of a 40-hour work week. Guidance for Indoor Air Quality Investigations. 1988. Table Z-3. Acute health effects: No acute health effects are known but chronic exposure may lead to increased risk of lung cancer from alpha radiation. The combined effect of these multiple stressors may interact with employees and could result in acute adverse emotional or physical reactions. Carbon Dioxide. This is equivalent to approximately 15 ppm diesel vapor. Much of the specialized equipment is available through the OSHA Health Response Team (HRT), Cincinnati Technical Center (CTC), or Regional Offices. Ventilation efficiency can be improved by: Ensuring that outdoor air-supply dampers and room air-vents are open; Removing or modifying partitions or obstructions that block fresh-air flow; Rebalancing the system to prevent inflow or outflow of contaminated air due to pressure differentials between rooms; Preventing poor distribution of make-up air by proper placement of air inlets and exhausts; and. Cal/OSHA has established an extensive list of PELs (Cal/OSHA AC-1 Table) that are enforced in workplaces under its jurisdiction. 4 II. In many IAQ investigations, extensive air monitoring may not be warranted because inadequate introduction and/or distributions of fresh air may be the main problem. Recommendations include programs that change the behavioral patterns of occupants. However, levels at poultry plant inspectionstations range from about 900 to 3,500 ppm (depending on how close the inspection station is to the dry . American Review of Respiratory Disease 136:1486-1508 and 137:221-242. 1989. (a) The unshaded area on this page Lists PELs from OSHA Table Z-2 in 29 CFR 1910.1000. These organizations periodically make revisions to their OELs and so they should be consulted directly for their most current values and substances, as well as special notations such as for skin absorption. (i) This standard applies to any operations or sectors for which the exposure limits in the beryllium standard, 1910.1024, are stayed or is otherwise not in effect. Web site accessed on October 18, 2019. (c) The CAS number is for information only. To provide employers, workers, and other interested parties with a list of alternate occupational exposure limits that may serve to better protect workers, OSHA has annotated the existing Z-Tables with other selected occupational exposure limits. Fisk, W. J. et al. Wadden, R. A., and Scheff, P. A. Atlanta: ASHRAE. OSHA has chosen to present a side-by-side table with the Cal/OSHA PELs, the NIOSH Recommended Exposure Limits (RELs) and the ACGIH TLVss. 12/23/2020 - Review of the Ozone NAAQS - Final Decision; 7/13/2020 - Review of the Ozone NAAQS - Proposed Decision; Additional . ACGIH is a private, not-for-profit, nongovernmental corporation. During an 8-hour work shift, an employee may be exposed to a concentration of Substance A (with a 10 ppm TWA, 25 ppm ceiling and 50 ppm peak) above 25 ppm (but never above 50 ppm) only for a maximum period of 10 minutes. OSHA enforces these limits under section 5 (a) (2) of the OSH Act. Environmental Protection Agency (EPA). Man-Made Mineral Fibres and Radon. Permission must be requested from ACGIH to reproduce the TLVs and BEIs. "Items to Consider When Investigating Complaints Relative to the Office Environment." OSHA's annotated PELs tables include a side-by-side comparison of OSHA PELs, Cal/OSHA PELs, NIOSH RELs and ACGIH TLVs. ASHRAE Standard 55-1981. Before biological sampling, several precautions must be taken including making arrangements for preparing culture media for sampling, specialized shipping procedures, and making arrangements for analysis by a laboratory familiar with the handling and processing of biological samples. 1987. Most indoor air particulates are due to tobacco smoke and are in the respirable range. Eliminate or control all known and potential sources of microbial contaminants by prompt cleanup and repair of all areas where water collection and leakage has occurred including floors, roofs, HVAC cooling coils, drain pans, humidifiers containing reservoirs of stagnant water, air washers, fan coil units, and filters. The TLVs in the annotated tables are reprinted with permission from ACGIH. ACGIH has established TLVs for compounds not included in the OSHA Z Tables. . Use screening techniques to determine the potential sources that may require more sensitive and accurate evaluation or may require action as described in Section E, depending upon professional judgment. In particular, ACGIH provides an explanation of the use of TLVs and access to documentation. Acute health effects: Allergic reactions such as hypersensitivity diseases (hypersensitivity pneumonitis, humidifier fever, allergic rhinitis, etc.) (i) In 29 CFR 1000, all inert or nuisance dusts, whether mineral, inorganic, or organic, not listed specifically by substance name are covered by the Particulates Not Otherwise Regulated (PNOR) limit which is the same as the inert or nuisance dust limit of Table Z-3. The most effective engineering control for prevention of indoor air quality problems is assuring an adequate supply of fresh outdoor air through natural or mechanical ventilation. What type of copying machines, signature machines, spirit duplicators, blueprint machines and other office machines are used in the vicinity of complaints or in areas serviced by the same ventilation system? 29 CFR 1910.1000 [82 FR 2735, January 9, 2017]. Occupational Safety and Health Administration (OSHA) (2017) Air Contaminants. In addition to the values listed in this table, the Z tables in 29 CFR 1910.1000 list skin absorption designations. Microorganisms and Other Biological Contaminants (Microbials). Em is the equivalent exposure for the mixture. For example, the World Health Organization (WHO) categorizes indoor organic pollutants as: To achieve compliance with paragraphs (a) through (d) of this section, administrative or engineering controls must first be determined and implemented whenever feasible. Modern office buildings are generally considered safe and healthful working environments. .Cn Tn) 8 Initial sampling will normally consist of collecting environmental data using grab or screening samples with direct reading equipment such as detector tubes, particulate monitors, air velocity measuring instruments, and psychrometers. Two hours exposure at 75 ppm The TLVs and BEIs are copyrighted by ACGIH and are not publicly available. TLV: between 0.1 and 0.3 ppm (6). Note: This table only includes occupational exposure limits (OELs) for substances listed in the OSHA Z-2 Table. For increased sensitivity, higher flow rates or longer sampling times may be used. Sources: Tobacco smoke, fossil-fuel engine exhausts, improperly vented fossil-fuel appliances. Supply adequate ventilation during and after completion of work to assist in diluting the contaminant levels. See http://www.acgih.org/. ASHRAE, p. 34-38. Levels of carbon monoxide inside buildings should not exceed 9 ppm. See 1910.1028 for specific circumstances. ACGIH has established TLVs for compounds not included in the OSHA Z Tables. IARC Monographs. = Chemical Abstract Service Number hr = hour m 3 = cubic meters mg/m 3 = milligram per cubic meter Key signs or symptoms associated with exposure to VOCs include: conjunctival irritation nose and throat discomfort headache allergic skin reaction dyspnea declines in serum cholinesterase levels nausea emesis epistaxis fatigue dizziness Biological Exposure Indices (BEIs) are guidance values for assessing biological monitoring results concentrations of chemicals in biological media (e.g., blood, urine). OSHA responds to questions about standards with letters of interpretation. People who wear contact lenses often complain of burning, itching, and tearing eyes when exposed to cigarette smoke.6 Tobacco smoke is a major contributor to indoor air quality problems. (l) This 8-hour TWA applies to respirable dust as measured by a vertical elutriator cotton dust sampler or equivalent instrument. Provides links and references to additional resources related to indoor air quality. The TLVs and BEIs are copyrighted by ACGIH and are not publicly available. Each of the alternative lists of exposure limits is accompanied by extensive explanatory language on their source websites. Although asbestos and radon have been listed below, acute health effects are not associated with these contaminants. Physical hazards including noise from nearby sources such as air conditioning systems and printers, inadequate lighting, stress from the operation of video display terminals (VDT's), vibration sources, extremes of heat, cold and humidity, drafts, and poor air circulation. The TLVs and BEIs are copyrighted by ACGIH and are not publicly available. The walkaround inspection should cover all the affected areas. 1984. Has there been any recent renovation or maintenance that can be a source of contaminants, such as painting, carpet installation, air conditioning repairs, use of acid drain cleaners, carpet cleaning, disinfecting of HVAC system, pesticide application? For the most current OELs and information on notations such as skin absorption, users should consult complete listings and explanations from Cal/OSHA, NIOSH, and ACGIH. Does the frequency and type of maintenance performed on the HVAC systems, such as cleaning and oiling, meet the HVAC manufacturer's recommendations: filter change; prevention of bacterial buildup by use of biocides; repair and cleanup of water leaks; operating fresh air intake damper; and system balance checks? NIOSH transmits its recommendations to OSHA for use in developing legally enforceable standards. Investigating Office-Related Complaints, Appendix III:2-2. 1987. Cal/OSHA PELs are promulgated under statutory requirements for risk and feasibility that are no less protective than the OSH Act. Choose sampling procedures that can determine concentrations of toxic materials that are much lower than are normally found in industrial investigations. Sources: Paints, cleaning compounds, moth-balls, glues, photocopiers, "spirit" duplicators, signature machines, silicone caulking materials, insecticides, herbicides, combustion products, asphalt, gasoline vapors, tobacco smoke, dried out floor drains, cosmetics and other personal products. Often employee complaints result from items such as cigarette smoke, odors, low-level contaminants, poor air circulation, thermal gradients, humidity, job pressures, lighting, work-station design, or noise. During the walkaround inspection, the investigator could determine the building characteristics, discuss with knowledgeable personnel the proper operation of the HVAC systems, verify information obtained from the employer and employee interviews, perform ventilation-system testing, and, if appropriate, collect screening samples to identify potential causes of the problem. NIOSH has established occupational exposure limits for compounds not included in the OSHA Z Tables. Provides a series of questions and answers about indoor air quality. Example. Contamination from outside building - 10%. Legionella pneumophila is often present in hot water tanks, washing systems, and pools of stagnant water, but health effects are not observed until the contaminants become aerosolized within the building confinements. Temperature control in the range of 68-76 F. Checking damper positions and functioning belts, baffles, ductwork, and system balance; Measuring airflow and performing necessary adjustment if necessary to meet ASHRAE recommendations; Replacing filters on air handling units at regular intervals; Cleaning air distribution ducts and dampers; and. (e) ACGIH Threshold Limit Values (TLVs) (ACGIH). 1981. TLVs and BEIs are health-based values and are not intended to be used as legal standards. However, OSHA recommends that employers consider using the alternative occupational exposure limits because the Agency believes that exposures above some of these alternative occupational exposure limits may be hazardous to workers, even when the exposure levels are in compliance with the relevant PELs. Health Effects and Sources of Indoor Air Pollution. It is produced by the incomplete burning of various fuels, including coal, wood, charcoal, oil, kerosene, propane, and natural gas. What is the magnitude and distribution of employee complaints or illnesses? If carbon dioxide levels exceed 1,000 ppm it does not necessarily indicate that the building is hazardous and should be evacuated. Personnel affected with hypersensitivity should be thoroughly evaluated and the problem identified and corrected before returning them to the workplace. Indoor Pollution: Guidelines for Prevention and Control of Microbiological Respiratory Hazards Associated with Air Conditioning and Ventilation System. Acute health effects: Tobacco smoke can irritate the respiratory system and, in allergic or asthmatic persons, often results in eye and nasal irritation, coughing, wheezing, sneezing, headache, and related sinus problems. Consistent levels of 1500 ppm and above indicate that the room is badly ventilated. . Adjust combustion sources such as furnaces or water heaters to assure proper burning and exhaust to an area where re-entrainment will not occur. The Consumer Product Safety Commission recommends levels not to exceed 15 ppm for 1 hour or 25 ppm for 8 hours. 43. Poor indoor air quality (IAQ) has been tied to symptoms like headaches, fatigue, trouble concentrating, and irritation of the eyes, nose, throat and lungs. E is the equivalent exposure for the working shift. The General Duty Clause of the OSH Act (the law that created OSHA) requires employers to provide workers with a safe workplace that does not have any known hazards that cause or are likely to cause death or serious injury. American Society for Heating, Refrigerating and Air-conditioning Engineers (ASHRAE). To evaluate thoroughly, collect samples at fresh-air intakes, near return-air ducts, adjacent to both indoor and outdoor potential sources of contaminants, and in employee work areas both for complaint and noncompliant areas. The ACGIH5 recommends a pre-assessment of the extent of microbial contamination prior to initiation of air sampling. Acute health effects: Asbestos is normally not a source of acute health effects. NIOSH has established occupational exposure limits for compounds not included in the OSHA Z Tables. Acceptable levels of TVOC ranges from 0.3 to 0.5 mg/m3 of concentration. Carbon monoxide (CO) is a deadly, colorless, odorless, poisonous gas. Based upon current information, it is advisable to mitigate formaldehyde that is present at levels higher than 0.1 ppm. Air Sampling Instruments for Evaluation of Atmospheric Contaminants (6th ed.). Acute health effects: Irritation to the eyes, skin and lungs; dermatitis. Benzene If ventilation is turned off during weekends or other periods, ensure that system is on so that contaminant concentrations are sufficiently diluted prior to occupancy. Low range detector tubes are available from manufacturers. Cal/OSHA has established occupational exposure limits for compounds not included in the OSHA Z Tables. Indoor Air Quality. 0.0002 mg/m3 (8-hr-TWA)See Appendix ASee Appendix C. (a) The unshaded area on this page lists PELs from OSHA Table Z-1 in 29 CFR 1910.1000. American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). Are heating, ventilating, and air-conditioning systems being operated and maintained properly with respect to location of air intakes and exhausts, pressure differentials between rooms that may account for influx of contaminants, design for supplied outdoor air, flow and distribution of air, position of dampers, local exhaust ventilation, air-cleaning equipment, HVAC operating times, regular operation checks, equipment cleaning and disinfecting, presence of water leaks or standing water, water-damaged building materials, and bacteriological contamination? Section 6(a) of the OSH Act granted the Agency the authority to adopt existing Federal standards or national consensus standards as enforceable OSHA standards. Note: This table only includes occupational exposure limits (OELs) for substances listed in the OSHA Z-1 Table. ACGIH does not believe that TLVs and BEIs should be adopted as standards without an analysis of other factors necessary to make appropriate risk management decisions (e.g., control options, technical and economic factors, etc.). 1986. Two hours exposure at 150 ppm Two hours exposure at 75 ppm Four hours exposure at 50 ppm Substituting this information in the formula, we have (2 150 + 2 75 + 4 50) 8 = 81.25 ppm Since 81.25 ppm is less than 100 ppm, the 8-hour time weighted average limit, the exposure is acceptable. In addition, some exposures, such as asbestos and radon, do not cause immediate symptoms but can lead to cancer after many years. A simple traverse of the fresh-air intake duct may provide adequate information to determine the fresh-air flow. What are the complaints and associated symptoms experienced; when do they occur (season, time, days, frequency); where do they occur; how long do symptoms last; do they clear up after leaving work (how soon); have the symptoms been triggered by any specific event or in any specific area; what is the source of symptoms; was any medical diagnosis or care rendered? American Society for Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). Click here for permission request form. OSHA enforces these limits under section 5(a)(2) of the OSH Act. Applied Industrial Hygiene 2(5):RIO to R16. The tables list air concentration limits, but do not include notations for skin absorption or sensitization. (n) See Table Z2 for the exposure limits for any operations or sectors where the exposure limits in 1910.1024 are stayed or otherwise not in effect. TVOC can be measured in micrograms per cubic meter (g/m3) of air, milligrams per cubic meter (mg/m3), parts per million (ppm) or parts per billion (ppb). Using room fans to improve mixing and dilution of pollutants. Em= 0.500 + 0.225 + 0.200 OSHA dictates that the minimum "safe level" of oxygen in a confined space is 19.5%, while the maximum "safe level" of oxygen in a confined space is 23.5%. Indoor Air Quality Control Techniques. However, it is still acceptable for the TVOC to be up to 0.5 mg/m3 or 500 ug/m3. Airborne microbials sampling equipment is available from the HRT if sampling is necessary. The shaded area of this page lists other occupational exposure limits (OELs) from Cal/OSHA, NIOSH, and ACGIH. The following States have Indoor Air regulations: California New Jersey Contact the Salt Lake Technical Center (SLTC) with any sampling questions.

Therefore, some products that are labeled as "no VOC" or "low VOC" under the CAA can actually contain volatile organic chemicals that are toxic, sometimes at high levels. Occupational Safety & Health Administration, Occupational Safety and Health Administration, Outreach Training Program (10- and 30-hour Cards), OSHA Training Institute Education Centers, Severe Storm and Flood Recovery Assistance, Permissible Exposure Limits - Annotated Tables. BEIs represent the levels of determinants that are most likely to be observed in specimens collected from healthy workers who have been exposed to chemicals in the same extent as workers with inhalation exposure at the TLV. Is smoking allowed in the office, in adjacent areas or in areas serviced by the same ventilation system? Based on initial sampling, further investigations may be performed using standard OSHA sampling procedures listed in the OSHA Analytical Method Manual. Of all the states that have OSHA-approved State Plans, California has the most extensive list of OELs. Where: Reduction of job stress by: (a) adequate flow of information from management to employees; (b) explanation of any changes introduced into the workplace including new chemicals, ventilation, production modification, and work schedules; (c) maximizing employee participation in planning and implementing changes; (d) stress reduction techniques including exercise, biofeedback, and assertiveness training; and (e) training workers to understand chemicals they may be working with and their health effects, dose/response relationships, and results of environmental evaluation.

National Institute for Occupational Safety and Health (NIOSH) (2019) NIOSH Pocket Guide to Chemical Hazards. Em= 0.925 250 to 2000 ppb Look for VOC sources if this average level persists for a month. This document contains a high level discussion of indoor air quality given that ASHRAE has published many informative documents related to indoor air quality such as the Handbook -- Fundamentals (ASHRAE 2017a) (particularly Chapters 9 through 12) and two IAQ guides: "Indoor Air Quality Guide - Best Practices for Design, Construction and The 62-1989 standard recommends a minimum of 15 CFM of outdoor air per person for offices (reception areas) and 20 CFM per person for general office space with a moderate amount of smoking. The following States have Indoor Air regulations: The purpose of this webpage is to give workers and employers useful, up-to-date information to identify, correct, and prevent IAQ problems. Room air in which contaminants are generated should be discharged directly outdoors rather than recirculated. Applied Industrial Hygiene 1:R19-R23. However, during renovation or maintenance operations, asbestos may be dislodged and become airborne. An employee's exposure to any substance listed in Tables Z-1, Z-2, or Z-3 of this section shall be limited in accordance with the requirements of the following paragraphs of this section. (g) National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limits (RELs) from the NIOSH Pocket Guide to Chemical Hazards (https://www.cdc.gov/niosh/npg) (Web site last accessed on October 18, 2019). Most of OSHA's PELs were issued shortly after adoption of the Occupational Safety and Health (OSH) Act in 1970, and have not been updated since that time. If levels inside a building are detected greater than 100 ppm, the building should be evacuated until the source is identified and corrected. Acute health effects: Eye, respiratory tract, mucous membrane irritation; aggravation of chronic respiratory diseases. 8-47, Table N1) concurred that the proposed limits were appropriate. While the exact short and long term carbon monoxide levels recommended by ASHRAE, OSHA, NIOSH and other organizations differ, the consensus is that. (Volatile Organic Compounds, Indoor Air Quality and Health, Vol. They include headache, dizziness, nausea, tiredness, lack of concentration, and eye, nose, and throat irritation. Ergonomic problems such as carpal tunnel syndrome or inflammatory disorders of the tendons and joints of keyboard operators due to tasks requiring repetitive motions. Evaluation and testing of the HVAC system should follow the procedure established in the Ventilation Investigation chapter of the OTM. See http://www.acgih.org/. The OSHA standard for workers is no more than 50 ppm for 1 hour of exposure. Sources: Ground beneath buildings, building materials, and groundwater. RELs are for up to 10-hour time weighted averages (TWAs) during a 40-hour work week unless otherwise indicated. TLV: between 750 and 1,000 ppm (7). 200 ppm or greater will cause physical symptoms and is fatal in hours. Sources: Cigars, cigarettes, pipe tobacco. The synergistic effect of multiple stressors appears to indicate that building-related problems may be more than an air quality problem.
