The main toxic effect of peracetic acid is local irritation especially of the mucous membranes of the respiratory tract and the skin, depending on the kind of exposure. The … / The AEGL-2 value is 1.56 mg/m 3 (0.5 ppm) for all exposure durations from 10 min to 8 h based on an exposure concentration of 4.7 mg/m 3 (1.5 ppm), which, according to Fraser and Thorbinson (1986), is expected to be associated with slight to tolerable discomfort to nasal membranes and eyes for exposure durations up to 20 min. Numerous accounts have documented acute nasal and eye irritation, shortness of breath, and upper respiratory symptoms following exposure to PAA, such as those found in a recent Health Hazard Evaluation conducted by NIOSH (. Sampling specifically for PAA requires high selectivity because, when in solution with water, it degrades quickly into acetic acid and hydrogen peroxide, and so these parent compounds are always present when there is PAA present, in the water and in the air. Page 1 of 5 C:\Users\jrobinson.CHEMDAQ2\Dropbox\Food & Beverage\Symptoms of Exposure to Peracetic Acid Vapor Feb 2016.doc Symptoms of Exposure to Peracetic Acid Vapor Richard Warburton February 2016 Introduction During a recent visit to National Beef in Liberal, KS, the question was raised concerning at what concentration of peracetic acid (PAA) vapor would people start to experience irritation and so complain. A solution was prepared in the laboratory at 250 ppm hardness to which each indicated amount of PAA was added. 1. Peracetic acid, an excellent chemical disinfector, was recommended for the public disinfection by the Ministry of Health of China. Sampling and Use Considerations for Peracetic Acid. The challenge for evaluating and controlling PAA exposure and the potential health effects specifically within the poultry industry is the variability of the PAA concentration and the wide range of environmental conditions on the processing floor (temperature, humidity, and the presence of other disinfection chemicals). These sensors have become commercially available in the past several years and are evolving in terms of accuracy and sensitivity. Our products are designed for small to medium size companies willing to optimize But despite the significant benefits of PAA use, there are ongoing concerns about the health and safety of those exposed to PAA while working with the chemical. Use permanent link to share in social media. We are a team of passionate people whose goal is to improve everyone's 3. Please login to send this document by email! The lack of reliability of the sampling methods indicates a need for additional research into a more stable, robust method that gives consistent results. hydrogen peroxide, peracetic acid, and acetic acid, and listed symptoms experienced by employees, including respiratory distress, skin problems, headaches, … 7 http://www.cdc.gov/niosh/docket/review/docket156a/pdfs/g1-013---peracetic-acid-cas-79-21- 0.pdf. 6 Peracetic Acid documentation for STEL TLV. Chemical Risks and Hazards. Shortness of breath when hurrying on level ground or walking up a slight hill was significantly associated with increased exposure to the oxidant mixture (P = 0.017), as well as the TM (P = 0.026). To help employers provide training about PAA and other chemicals used in food disinfection and sanitation, the Safety, Health, and Environmental Services group at Georgia Tech developed a, Finally, every facility should establish a risk management plan for the use of PAA in the facility. The panels who determine exposure limits also include a large safety factor and so exposure limits are usually below the concentration where symptoms are problematic. 6 NIOSH IDLH NIOSH is currently considering an Immediately Dangerous to Life and Health Limit for PAA and has circulated a draft document. Conflicting results from air sampling in areas of poultry processing plants with established employee complaints and reported symptoms of eye and respiratory irritation could further complicate the resolution of these employees’ concerns, casting doubt on both the sampling results and the complaints. NIOSH has begun exploring the relationship between airborne exposure to all three chemicals and the potential additive effects. The results for higher PAA concentrations are summarized in the table below (data cited from Fraser & Thompson (1986).

Discussion The development of occupational exposure limits includes more than just the obvious symptoms of exposure. business problems. The American Conference of Governmental Industrial Hygienists (ACGIH) Board of Directors has approved the new 2014 occupational exposure limits, including a new Short Term Exposure Limit (STEL) for Peracetic Acid (PAA). This report provides a summary of the available literature to answer this question. One reason for taking a conservative approach is that the effects of exposure can vary greatly from one person to the next. Included among these chemicals is peracetic acid. Based on the published reports discussed above, 0.5 ppm is considered the threshold for irritation, so people may start to experience irritation, but would probably not experience enough irritation to complain. Three levels— AEGL-1, AEGL-2 and AEGL-3—are developed for each of five exposure periods (10 and 30 min, 1 h, 4 h, and 8 h) and are distinguished by varying degrees of severity of toxic effects. ACGIH STEL TLV = 0.4 ppm (15 min TWA). Slight to tolerable discomfort in the nose is experienced at 1.5 ppm and above for up to 20 minutes, significant irritation over 2 ppm. This includes informing affected employees how to report health and safety concerns—including symptoms potentially related to chemical exposure—to their employer without fear of retaliation. For a plant manager looking to assess airborne concentrations of PAA, the “Non-Agency Method 57” (. Respiratory Symptoms in Hospital Cleaning Staff Exposed to a Product Containing Hydrogen Peroxide, Peracetic Acid, and Acetic Acid Brie Hawley*, Megan Casey, Mohammed Abbas Virji, Kristin J. Cummings, Alyson Johnson, and Jean Cox-Ganser Respiratory Health Division, National Institute for Occupational Safety and Health, CDC, 1095 This is the first report of VCD onset following exposure to several irritants: formaldehyde, glutaraldehyde, sopropylic alcohol, peracetic acid-hydrogen peroxide mixture. Ensure the Safety and Health of all people potentially exposed to hazardous chemical vapors in the workplace. As an alternative, site safety and health managers could purchase a variety of personal and handheld monitoring systems for PAA that are intended to measure exposures in real time. Therefore, PAA can be smelt at a concentration well below occupational exposure limits (e.g. Peracetic acid is used as a disinfectant. life through disruptive products. Irritation occurs at 0.5 ppm or higher over long durations for some individuals. Lastly, if the facility uses concentrated PAA in a 60 percent or higher concentration and has more than 1,000 pounds onsite (approximately 115 gallons), the company would also need to comply with the process safety management standard. These systems can be tracked remotely and have alarms to alert personnel to a concern. Cleaning and disinfectant products are widely used in health care settings to minimize health care-acquired infections (HAIs). The plan should identify risks, estimate impacts, define responses to risks, and develop planned responses. Work-related acute nasal and eye irritation, and shortness of breath were significantly associated with increased exposure to hydrogen peroxide, peracetic acid, and acetic acid, indicating an increase in symptoms with increasing exposure to the mixture of vapors from the sporicidal product. Some companies also offer single-point, stationary continuous monitoring systems for PAA, similar to an ammonia or carbon monoxide detector. These levels can be loosely translated as: • irritation (AEGL -1), •disabling irritation or permanent injury (AEGL-2), First, the PEL for hydrogen peroxide is 1 ppm and the PEL for acetic acid is 10 ppm, but with PAA there is an ACGIH STEL of 0.4 ppm. Industrial hygienists should also review the company’s hazard communication program and injury and illness reporting program. • An inhalation challenge test to peracetic acid-hydrogen peroxide mixture resulted in a specific and late asthmatic response. However, industrial hygienists recognize that it is also highly corrosive and a strong oxidizer, and exposure to peracetic acid can severely irritate the eyes, skin, and respiratory system. HAIs are estimated to cost the US health care industry $8.5–11.3 billion annually (Zimlichman et al., 2013). We detected hydrogen peroxide, peracetic acid, and acetic acid in all full-shift air samples. A short term acute exposure to hydroquinone may cause a variety of symptoms including, but not limited to, headaches, dizziness, nausea, and difficulty breathing. Respiratory Protection: Use a NIOSH approved respirator when exposure limits are exceeded or if irritation or other symptoms are experienced. There are three levels of AEGL corresponding to the severity of symptoms of exposure. Peracetic acid products containing more than 15% peracetic acid demonstrate excessive reactivity, instability, and some degree of explosiveness [Pechacek et al. * Breathing Peroxyacetic Acidcan irritate the lungs causing coughing and/or shortness of breath. All parties (frontline employees, managers, wastewater treatment employees, maintenance workers, and so on) associated with the application of PAA must not only receive but also be able to understand the training on the health effects of exposure to PAA. We found that increased exposure to hydrogen peroxide, peracetic acid, and acetic acid vapors was associated with increases in acute work-related nasal and eye symptoms The PAA solution was kept at 70° F throughout the test The high costs associated with HAIs have increased demand for effective cleaning and disinfection products that can reduce infectious bacteria like methicillin-resistant Staphylococcus aureus, vancomycin-resistant Enterococcus, and Clostridium difficile (C. diff) in health … We have found, for example, in our role as researchers at Georgia Tech, that in very wet, cold environments the sensors’ batteries drained quickly; and if water droplets or condensation formed inside the tubing, the sensor would exhibit a wide range of readings until the sensor was allowed to completely dry out. Acute exposure to peracetic acid is irritating to the eyes, respiratory tract, and skin. According to OSHA, peracetic acid can cause burns and respiratory illness if not handled safely. Peracetic Acid 0.4 ppm TWA (inhalable fraction and vapor) proposed ACGIH TLV Engineering Controls: Use with adequate general or local exhaust ventilation to main exposure levels below the occupational exposure limits. What concentration of peracetic acid (PAA) vapor will cause people to start to experience irritation and to complain? Page 5 of 5 C:\Users\jrobinson.CHEMDAQ2\Dropbox\Food & Beverage\Symptoms of Exposure to Peracetic Acid Vapor Feb 2016.doc Conclusions  There is very little published data on the effect of low concentration PAA vapor on humans. During ChemDAQ’s on- site survey at national Beef, the readings went up to about 0.3 and 0.4 ppm. However, safety and health managers should take into consideration that PAA is highly reactive and breaks down over time and distance from the source of exposure. IDLH values are based on a 30 minute exposure duration. EPA’s National Research Council (US) Committee on Acute Exposure Guideline Levels reports “peracetic acid can be corrosive/irritating to the eyes, mucous membranes of the respiratory tract, and skin. These requirements present challenges to accurate measurement and interpretation of results. Results indicated that most of the 247 participants suffered from the di scomfort of skin, eyes, and respiratory tracts, and cough was the most common symptom (43.9% for nonprofessionals and 68.1% for nurses); 72.3% of the nurses suffered from skin burn, lacrimation, and/or eye pain as well as cough after the exposure of 8 hour s per day in the hospital where 0.5% peracetic acid was sprayed 3 to 5 times a … The EMEC Peracetic Acid Analyzer and Control System, offers ease of use, accuracy and reliability for the monitoring and control of Peracetic Acid in water. Another complication is the possibility that the presence of chlorine affects the chemistry of PAA, especially when the chemicals mix in the drain lines on the production floor. There are several reasons why sampling for hydrogen peroxide and acetic acid as a proxy for PAA is potentially problematic. Employees across all sectors where PAA is used report symptoms of discomfort and illness, and actual exposure levels in facilities vary greatly day to day. FIRST AID MEASURES General Advice Liquid and mist are corrosive and can cause burns, direct contact could cause irreversible dmage to eyes including blindness and/or irreversible destruction of skin tissue. Therefore, a sensor positioned on a wall ten feet from the source may not accurately report what employees are experiencing while working closer to the application of the PAA solution, which in many cases is within 1–2 feet. This obligation stands regardless of whether an employer has quantified the level of chemical exposure (including peracetic acid, for example) in the workplace, as some individuals may have higher sensitivities than others. Symptoms irritation eyes, skin, nose, throat; eye, skin burns; skin sensitization; dental erosion; black skin, hyperkeratosis; conjunctivitis, lacrimation (discharge of tears); pharyngeal edema, chronic bronchitis Using the EMEC LDSCL PLUS Peracetic Acid analyzer and controller and the latest in Amperometric Cell Technology, Peracetic Acid ppm readings are continuous and updated every second. As the concentrated form of the chemical is diluted and introduced into a plant, the ventilation in a facility becomes a critical mechanism to control airborne concentrations of PAA. The PeraSense CH 3 CO 3 H analysers are undeniably the most cost effective CH 3 CO 3 H analysers available. Peracetic acid (CH3COOOH) is used as a decontaminant with limited application. 5 ACGIH STEL TLV The ACGIH documentation for development of the STEL TLV relied on the same reports regarding symptoms as a function of PAA concentration as the AEGL committee. One person may notice a smell but their neighbor has significant eye irritation. 5 ACGIH STEL TLV The ACGIH documentation for development of the STEL TLV relied on the same reports regarding symptoms as a … This presents a challenge for field application in poultry/food processing settings where the use of chlorine is prominent, frequent, and concurrent with the use of PAA. Corrosive Effects of Peroxyacetic Acid Experimental Methods: Corrosion coupons of the various metals were suspended in the various concentrations of PAA for 30 days. The company has since upgraded their air handler and are keeping the concentrations low and worker complaints have stopped. STEL = Threshold Limit Value—Short-Term Exposure Limit (TLV–STEL). Based on those reports, the answer appears to be that most people will experience symptoms worth complaining about for PAA concentrations between 1.5 and 2 ppm.  The odor threshold is around 50 ppb, well below the ACGIH STEL TLV. Higher exposures can cause a build-up of fluid in the lungs (pulmonary edema), a medical emergency, with severe shortness of breath. EPA Suggested Exposure Limits for Public •The EPA has issued Acute Exposure Guideline Levels (AEGLs) for peracetic acid. Methods have been developed to simultaneously sample hydrogen peroxide and peracetic acid, as these chemicals are thought to cause the associated irritant symptoms. In health hazard evaluations conducted by NIOSH, sampling was completed where PAA was in use and symptoms persisted among employees, but exposures to acetic acid and hydrogen peroxide returned below the limits of detection or well below the exposure limits. Page 3 of 5 C:\Users\jrobinson.CHEMDAQ2\Dropbox\Food & Beverage\Symptoms of Exposure to Peracetic Acid Vapor Feb 2016.doc 4 In contrast You et al (2006) found that 2.1 mg/m 3 over 8 hours resulted in lacrimation, eye and skin irritation and coughing. The most commonly reported symptoms in the health and work history questionnaire were nasal problems and watery eyes. We build great products to solve your 2. There was definitely an odor of PAA during these tests but little or no irritation was experienced. Therefore, 1.56 mg/m 3 (0.5 ppm) is considered to be the threshold for irritation to mucous membranes and eyes. 4 http://www.epa.gov/sites/production/files/2014- 09/documents/peracetic_acid_final_volume8_2010_0.pdf 5 “Evaluation of the toxicity data for peracetic acid in deriving occupational exposure limits: A mini-review. Respirator Protection: In operations where the occupational exposure limits are exceeded, an approved respirator with It leaves no residual behind (which makes it attractive for the enhancement of food safety sanitation procedures) and it breaks down to water, oxygen, and acetic acid (which lessens environmental impact after use). * High or repeated exposure may affect the liver and kidneys. 7 The IDLH is the maximum (airborne concentration) level above which only a highly reliable breathing apparatus providing maximum worker protection is permitted. Determining the ventilation rates in areas of the facility that use PAA, the direction employees face in relation to the PAA, and the presence of any “dead spaces” created by the building layout, cross ventilation, or the placement of machinery will help safety and health professionals develop a strategy to reduce employee exposure. Peracetic acid is a common disinfectant used throughout the medical industry which can prevent biofilm formation. OSHA had been sampling for hydrogen peroxide and acetic acid as a proxy for PAA until the agency published a partially validated method in November 2019. Peracetic acid is a liquid in which PAA and hydrogen peroxide are both present. An intraspecies uncertainty factor of 3 was applied to 1.56 peracetic acid mg/m3, because peracetic acid is a corrosive/irritant substance and the effects, which are confined to the upper respiratory tract, are expected to be similar for individuals within the population. With its myriad applications, the use and market share of peracetic acid (PAA)—a chemical that serves as both disinfectant and sanitizer in numerous industries, including healthcare, wastewater treatment, and the food industry—has grown rapidly over the past five years. Signs and Symptoms of Acute Peracetic Acid Exposure: Signs and symptoms of acute ingestion of peracetic acid may include corrosion of mucous membranes of mouth, throat, and esophagus with immediate pain and dysphagia (difficulty swallowing); ingestion may … 4. In regard to human symptoms of low concentration exposure, the IDLH committee is using the same references are the AEGL and ACGIH TLV exposure committees. Measured ppm concentrations of peracetic acid were divided by the occupational exposure limits proposed by multiple researchers, of 0.2 ppm.25, 26, 27 Hydrogen peroxide [HP], peracetic acid [PAA], and acetic acid [AA] represent the measured full-shift time weighted average.  0.5 ppm is the threshold for irritation to mucous membranes and eyes; 1.5 ppm is associated with slight to tolerable discomfort to nasal membranes and eyes for exposure durations up to 20 minutes; and 2 ppm and above results in significant irritation. PERACETIC ACID 35% W/H2SO4 SDS # : 79-21-0--35-1 Revision date: 2015-04-07 Version 1 4. The goal of this report is to assess what symptoms may be expected at various concentrations of PAA and thus at what concentration people are likely to complain. In addition, use of these devices for monitoring requires preparation: ensuring that all components are fully charged, syncing the connections between the sensors and the user interface, and allowing adequate time for zeroing-out the sensor prior to entering the work environment. PAA is potentially harmful at a concentration that is a whole order of magnitude smaller than either acetic acid or hydrogen peroxide. Each step of the process from the delivery of the product through the impact PAA has on wastewater treatment should be included in the plan. Respiratory Symptoms in Hospital Cleaning Staff Exposed to a Product Containing Hydrogen Peroxide, Peracetic Acid, and Acetic Acid October 2017 Annals of Work Exposures and Health 62(1) Most of these monitors are intended as spot-check devices (not to be worn by an employee per traditional air sampling methodologies), and sampling interference with other disinfection chemicals is possible. Pressure groups have demanded investigations to study the severe health effects of exposure to PAA in the workplace. • A biomedical scientist presented with clinical features of occupational asthma following a latent period of exposure to peracetic acid-hydrogen peroxide. Sampling and Use Considerations for Peracetic Acid BY JENNY HOULROYD, HILARIE WARREN, AND BOB HENDRY ... shortness of breath, and upper respiratory symptoms following exposure to PAA, such as those found in a recent Health Hazard Evaluation conducted by NIOSH (PDF).

Page 4 of 5 C:\Users\jrobinson.CHEMDAQ2\Dropbox\Food & Beverage\Symptoms of Exposure to Peracetic Acid Vapor Feb 2016.doc ChemDAQ’s Customers We installed a peracetic acid monitoring system in a beverage company using a PAA aseptic filling line. The exposure limit is set at a low value because of the risk of harm from non-symptomatic effects and include other data such as animal studies and biological tests for mutagenicity. The ChemDAQ monitors read up to 0.5 ppm during national Beef tests and workers in the area were not complaining. There is limited information on the mechanism of action regarding peracetic acid, but it is widely believed it operates similarly to other oxidizing agents, denaturing proteins and disrupting cell wall permeability. ... Peracetic Acid Acute Exposure Guideline Levels. And while peracetic acid is a versatile and effective disinfectant, it is also a known toxin and highly corrosive, and experts warn that exposure to the compound can severely irritate the eyes, skin and respiratory system. There will however be some people who experience irritation at lower concentrations and some hardy souls who will not complain for even higher concentrations. AEGL for selected airborne chemicals: Vol 8. Peracetic acid is a strong skin, eye, and mucous membrane irritant for both humans and animals, and continued skin exposure may cause liver, kidney, and heart problems. Page 3 of 5 C:\Users\jrobinson.CHEMDAQ2\Dropbox\Food & Beverage\Symptoms of Exposure to Peracetic Acid Vapor Feb 2016.doc 4 In contrast You et al (2006) found that 2.1 mg/m 3 over 8 hours resulted in lacrimation, eye and skin irritation and coughing. AEGLs 2 AEGLs represent threshold exposure limits for the general public and are applicable to emergency exposure periods ranging from 10 min (min) to 8 hs (h). 5. Workers were complaining of irritation of their eyes and noses. 2015]. Irritation Irritation occurs at a significantly higher concentration than the odor. Acetic acid has an OSHA PEL of 10 parts per million (ppm) or 25 mg/m 3 as an 8-hour TWA. There was no increase in irritation with exposure duration. Peracetic Acid Exposure Symptoms (from literature) Odor PAA has a strong vinegar like smell and it has an odor threshold around 0.05 ppm 1 (50 ppb). When the system was first installed it was continuously in alarm and often over 2 ppm. To date, no full-shift time-weighted average occupational exposure limit for peracetic acid has been established in the United States. This report provides a summary of the available literature to answer this question. N. Pechacek, M. Osorio, J. Caudill, B. Peterson, toxicology Letters (233, (2015), 45- 57, citing You Y, Bai Z, Gao X, (2006), “Peracetic acid exposure assessment during outbreak of SARS in Tianjin, China Epidemiol. One chemical commonly found on production floors with PAA is chlorine, which may potentially interact with PAA and can interfere with the detection capabilities of PAA sensors. ACGIH 2014.  The PAA values around 0.5 ppm recorded at National Beef are at the threshold of irritation and so any irritation experienced by workers would be mild and probably not sufficient for them to report it. Employers should not wait until there is a more perfect air sampling method before providing information to employees about the potential hazards associated with PAA—and this information, per OSHA’s hazard communication standard (29 Code of Federal Regulations 1910.1200), must be provided in a language and manner that employees can understand. In the eye, caustic/ irritating and harmful liquids cause, depending on the intensity of exposure, various levels of irritation, destruction, and ablation of the epithelium of the conjunctiva and cornea, corneal clouding, edema and ulcerations. The AEGL-1 value is 0.52 mg/m 3 (0.17 ppm) for all exposure durations from 10 min to 8 h. This value was derived from an exposure concentration of 1.56 mg/m3 (0.5 ppm), which, according to Fraser and Thorbinson (1986), is expected to cause no discomfort and according to McDonagh (1997) is not immediately irritating but would be unpleasant for an extended period of time. While there many published reports on the extent of occupational exposure, there have only been a few reports correlating the symptoms in humans to the PAA concentration. Public Channel their performance. PAA is instrumental in ensuring that a variety of products are safe for consumer use. For assistance in the development of a risk management plan, we recommended using the template from the U.S. Department of Health and Human Services’ Public Health Emergency website (, To get started with assessing PAA exposure at a job site, refer to two documents available from the Georgia Tech OSHA Consultation, Cal/OSHA: “Cal/OSHA Draft Substance Summary for the December 12, 2017 HEAC Meeting” (, Georgia Tech: “Peracetic Acid Exposure Assessment and Control Strategies for PAA: Planning Checklist” (, Georgia Tech: “Peracetic Acid Safety and Health Guide for Poultry Processing Facilities” (, NIOSH: “Evaluation of Exposure to a Hydrogen Peroxide, Peracetic Acid, and Acetic Acid Containing Cleaning and Disinfection Product and Symptoms in Hospital Employees” (, OSHA Salt Lake Technical Center: “Peracetic Acid” (, SKC: "SKC OSHA/NIOSH/ASTM Sampling Guide for Peracetic Acid" (, U.S. Department of Health and Human Services: “Risk Management Plan” (, BEST PRACTICES AND STRATEGIES FOR MANAGING PAA, series of hazard communication training videos, Simultaneous Sampling of Peroxyacetic Acid and Hydrogen Peroxide in Workplace Atmospheres.
