Toxic Substances Journal 5(3):162-181. Factors to be evaluated include inside and outside contamination sources; the HVAC system, e.g., location of air source, contamination, and proper operation; and occupational contributors, such as those listed in Appendix III:2-1. Thermal Environmental Conditions for Human Occupancy. SHRAE in its 62-1989 standard recommends 20 cubic feet per minute (CFM) of outdoor air per occupant for offices. = Chemical Abstract Service Number hr = hour m 3 = cubic meters mg/m 3 = milligram per cubic meter The Occupational Safety and Health Administration (OSHA) has set the STEL for formaldehyde at 2 ppm in 15 min and the permissible exposure limit time-weighted average (PEL-TWA) at 0.75 ppm. Rule History. NIOSH has determined that inadequate ventilation is the main problem in 52% of their IAQ investigations. Sources: Microfilm equipment, window cleaners, acid drain cleaners, combustion products, tobacco smoke, blueprint equipment. 1983. Viewable at http://www.dir.ca.gov/title8/5155table_ac1.html.

Any equipment and/or technical measures used for this purpose must be approved for each particular use by a competent industrial hygienist or other technically qualified person. Many factors affect IAQ. Such exposure must be compensated by exposures to concentrations less than 10 ppm so that the cumulative exposure for the entire 8-hour work shift does not exceed a weighted average of 10 ppm.

American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). Adjust combustion sources such as furnaces or water heaters to assure proper burning and exhaust to an area where re-entrainment will not occur. Where: Acute health effects: Irritation to the eyes, skin and lungs; dermatitis. (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. Computation formulae. The OSHA Health Response Team may be consulted for further information. ASHRAE, p. 34-38. Walsh, P. J., Dudney, C. S., and Copenhover, E. D. 1984. Appendix III:2-1. IARC Monographs. 1988. Are there sources of indoor contaminants that could lead to employee complaints (e.g., copy machines, signature machines, blueprint copiers, paints, cleaning compounds and disinfectants, tobacco smoke, adhesives and glues, off-gassing of construction material and building fabric, contaminants generated by construction or renovation, positive- or negative-pressure work areas, improperly vented gas appliances, air fresheners, pesticides)? The annotated tables contain links to the complete OEL lists from Cal/OSHA and NIOSH. it is recommended that OSHA or NIOSH limits be used for those individual compounds and that they not be included in the Total VOC value. (e) Milligrams of substance per cubic meter of air. NIOSH recommends no more than 35 ppm for 1 hour. Acute health effects: Eye, respiratory tract, mucous membrane irritation; aggravation of chronic respiratory diseases. 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.". Ergonomic problems such as carpal tunnel syndrome or inflammatory disorders of the tendons and joints of keyboard operators due to tasks requiring repetitive motions. Acute health effects: Allergic reactions such as hypersensitivity diseases (hypersensitivity pneumonitis, humidifier fever, allergic rhinitis, etc.) Building-related illnesses are those for which there is a clinically defined illness of known etiology and include infections such as legionellosis and allergic reactions such as hypersensitivity diseases and are often documented by physical signs and laboratory findings. During the walkaround inspection, professional judgment must be exercised to determine if samples should be collected to evaluate potential sources and potential contaminants including gases, vapors, and particulates. Based upon current information, it is advisable to mitigate formaldehyde that is present at levels higher than 0.1 ppm. At present, specialized bioaerosol sampling equipment is available through the OSHA Health Response Team. (b) Occupational Safety and Health Administration (OSHA) Permissible Exposure Limits (PELS) from 29 CFR 1910.1000 Z-1 Table [58 FR 35340, June 30, 1993; 58 FR 40191, July 27, 1993, as amended at 61 FR 56831, Nov. 4, 1996; 62 FR 1600, Jan 10,1997; 62 FR 42018, Aug. 4,1997; 71 FR 10373, Feb. 28, 2006; 71 FR 16673, Apr. These symptoms often disappear when the employee leaves the workplace. Appendix III:2-2. 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. Adopted by ACGIH with Intended Changes. Collect screening samples using detector tubes or direct reading instruments. (h) This standard applies to any operations or sectors for which the exposure limit in the Chromium (VI) standard, Sec. (d) 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/) (NIOSH Web site accessed on October 18, 2019). These office-related health problems can be evaluated by a consultant through employee interviews, analysis of job demands, and training employees. Exposure to PAA in the dilute form as a vapor or mist may sometimes cause eye, nose, throat and respiratory irritation that usually subsides when exposure ceases. Acute health effects: Difficulty concentrating, drowsiness, increased respiration rate. Acute health effects: Asbestos is normally not a source of acute health effects. .

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. Acetone Acetone is prevalent in polish and in most homes can be found in furniture polish, wallpaper and nail polish. Administrative and Work Practice Recommendations. Levels in Homes. Carbon monoxide (CO) is a deadly, colorless, odorless, poisonous gas. Web site accessed on October 18, 2019. Air Sampling Instruments for Evaluation of Atmospheric Contaminants (6th ed.). The HRT or Regional Offices may be contacted if sampling is to be initiated and for interpretation of the results. Some consensus standards from the American Standards Association were also adopted at that time, following the 6(a) procedures. Since 81.25 ppm is less than 100 ppm, the 8-hour time weighted average limit, the exposure is acceptable. Of all the states that have OSHA-approved State Plans, California has the most extensive list of OELs. Employee complaints can be due to two types of building problems: sick or tight building syndrome and building related illnesses. OSHA has established a Permissible Exposure Limit (PEL) for CO2 of 5,000 parts per million (ppm) (0.5% CO2 in air) averaged over an 8-hour work day (time . New Jersey: Noyes Data Corp. International Agency for Research on Cancer (IARC). 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. National Institute for Occupational Safety and Health (NIOSH). 1981. Since long-term exposure to VOCs can cause damage to the liver, kidneys and the central nervous system, the RESET standard formulates IAQ performance targets for an average daily exposure to TVOC concentrations, as listed in Table below. However, they can be purchased in their entirety on the ACGIH website at https://www.acgih.org/store/.
