The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) sets performance standards for energy efficient equipment. This includes air-conditioning and heating equipment. They are the first North American standards for energy efficiency for air-conditioning and heating equipment. Binder is an international group which is developing similar standards for cooling.
The American National Standards Institute and International Organization for Standardization also agree with the World Health Organization and US Environmental Protection Agency standards of 9 ppm of CO, 8 ppm of NO2 and 9 ppm of CO2 over a 8-hour period. The International Organization for Standardization has established an air quality limit in the workplace of 50 ppm of CO for a 8-hour time-weighted average.
Periodically, we should take a snapshot of the CO levels and compare them to the various standards. The ACGME requires performance measures for our OR. We can show a lack of adherence to these measures if the standards are not met. The performance measures for the OR must be measured periodically, and we can show compliance or non-compliance. We can show if the standards are being met or not.
The National Institute for Occupational Safety and Health (NIOSH) has a standard for the concentration of CO in the workplace. NIOSH accepts a level of 0.25 ppm over an 8-hour period as the threshold for the risk of incapacitation. This is slightly higher than the World Health Organization standard of 9 ppm.
The American College of Emergency Physicians (ACEP) has published standards for safe work environments in the OR. The ACEP has set standards for air quality in the OR. Air quality should be monitored. Medical personnel should be protected from excessive exposure to CO and other toxic gases. Proper venting should be provided. Staff should wear properly fitted PAPR and N95 respirators. Laboratorians and other laboratory staff should wear the appropriate PAPR and N95.
The OSHA PEL for carbon monoxide is not recommended because there are no data on the biological effects of carboxyhemoglobin levels. OSHA’s recommendation is based on the linear relation between carboxyhemoglobin (COHb) and mortality. However, carcinogens have a non-linear relation to the risk of cancer; the risk is greater at lower levels of exposure as well as longer exposure times. OSHA believes that this leads to an underestimation of the risk. OSHA feels that the no-observed-adverse-effect level for CO can be estimated to be 2.4 ppm of CO. OSHA believes that a worker’s ability to tolerate CO should be based on the amount of time spent in the atmosphere. While OSHA has not established a CO limit, OSHA feels that the current standard of 100 ppm is appropriate.
The concordances in Logos Bible Software are also the most extensive of any other concordance in the world. The concordance simply serves as a search tool, and most often than not the referenced works are already linked to the text, so searching for Moses will take you to the text of the Bible where it is first mentioned. 827ec27edc
