CITADEL PROJECT NO. 0069.1080.0 FORMALDEHYDE & PHENOL EXPOSURE MONITORING REPORT OCTOBER 2015 SAMPLING EVENT #1 SAN BERNARDINO COMMUNITY COLLEGE DISTRICT CRAFTON HILLS COLLEGE YUCAIPA, CALIFORNIA OCTOBER 14, 2015 1.0 BACKGROUND The Subject Site is a community college located at 11711 Sand Canyon Road in Yucaipa, California. Citadel Environmental Services, Inc. (Citadel) was contacted by San Bernardino Community College District (Client), C/O Crafton Hills College, to provide industrial hygiene air monitoring services. Citadel understands that personal exposure monitoring for formaldehyde and phenol is required for individuals (1-2 people at any one time) working with cadavers in the Crafton Hills College (CHC) Anatomy Department to evaluate existing engineering, respiratory and personal protective equipment needs. As such, Citadel was contacted by the Client to conduct exposure monitoring in the Cadaver Room during work with embalming fluid (containing formaldehyde and phenol). 2.0 SCOPE OF SERVICES All work was conducted by a knowledgeable and qualified Industrial Hygienist. Citadel s scope of work included the following: 1) Conducting employee exposure monitoring for formaldehyde and phenol in accordance with NIOSH Method 2016 and NIOSH Method 2546, respectively, and applicable standard industry sampling practices. Samples were collected during cadaver dissection activities. A total of four (4) air samples were taken: two (2) for formaldehyde and two (2) for phenol. Additionally, a total of two (2) field blanks were collected: one (1) for formaldehyde and one (1) for phenol. 2) Submitting the samples to an independent accredited laboratory for analysis. 3) Preparing an Exposure Monitoring Report to include all of Citadel s observations, sampling data and methodologies, results and conclusions, and any subsequent recommendations. The sampling and monitoring activities, as described above, were completed to determine the degree of exposure for an instructor working with embalming fluid, containing formaldehyde and phenol. Equipment and media appropriate to the specific sampling protocols were utilized to obtain samples during activities involving use of the embalming fluid, to determine the 8-hour time weighted average (TWA) exposures and short-term exposure limits (STEL) for the worker. The monitoring results were compared with recognized occupational exposure limits (Permissible Exposure Limits, Recommended Exposure Limits, Threshold Limit Values, etc.). 0069-1080-0_CHC_Sept-2015_Formaldehyde&Phenol_Exposure_ Monitoring_Report 1

CITADEL PROJECT NO. 0069.1080.0 FORMALDEHYDE & PHENOL EXPOSURE MONITORING REPORT OCTOBER 2015 SAMPLING EVENT #1 SAN BERNARDINO COMMUNITY COLLEGE DISTRICT CRAFTON HILLS COLLEGE YUCAIPA, CALIFORNIA OCTOBER 14, 2015 3.0 METHODOLOGY Air sampling was performed by Citadel s Project Industrial Hygienist, Ms. Jessica Small, during cadaver dissection activities on September 24, 2015. Air Sampling and Laboratory Analyses All of the air samples were delivered via courier to L.A. Testing in Garden Grove, California for analysis through appropriate test methods. L.A. Testing is accredited for the analysis of environmental and industrial hygiene samples by the American Industrial Hygiene Association (AIHA) and the National Environmental Laboratory Accreditation Program (NELAP). All samples were collected during the use of the formaldehyde and phenol mixture. Employee exposure monitoring and air sampling for formaldehyde and phenol was in accordance with NIOSH Method 2016 and NIOSH Method 2546, respectively, and applicable standard industry sampling practices. Samples were collected on solid sorbent tubes, attached to personal pumps via Tygon tubing. Sampling was performed during cadaver dissection tasks (opening of chest cavity). The flow rates of the sampling pumps were calibrated using a Drycal TM primary standard. Formaldehyde: A total of two (2) air samples were taken, in addition to one (1) field blank. Personal sampling pumps were calibrated to a flow rate of approximately 0.2 liters per minute (L/min) for the TWA sample and approximately 0.5 L/min for the STEL sample. Phenol: A total of two (2) air samples were taken, in addition to one (1) field blank. Personal sampling pumps were calibrated to a flow rate of approximately 0.1 L/min for the TWA sample and approximately 0.1 L/min for the STEL sample. 4.0 OBSERVATIONS, RESULTS, AND DISCUSSION The monitoring was performed on September 24, 2015. A walkthrough and brief interview with the instructor were completed to review chemical product use and existing safety controls. Field notes are presented in Appendix A. Walkthrough and Visual Inspection The following observations were noted during the investigation on September 24, 2015: The Anatomy & Physiology (A&P) Laboratory Technician (Employee ID #6850), donned appropriate personal protective equipment (PPE) prior to entering the Cadaver Room. PPE included full-face respirator with 3M 6005 formaldehyde/organic vapor cartridges and integrated glasses holder; scrubs, chemical-resistant full length apron, and chemical resistant gloves and sleeves. STEL and TWA samples for both formaldehyde and phenol were taken during the chest cracking procedure, when exposure is expected to be highest. Citadel placed pumps on the instructor around 09:20am before she entered the Cadaver Room. Citadel removed the STEL samples at 9:35am and TWA samples at 9:35am. Citadel noted a strong odor each time the A&P Lab Technician stepped out of the Cadaver Room to remove the STEL samples and TWA samples. 0069-1080-0_CHC_Sept-2015_Formaldehyde&Phenol_Exposure_ Monitoring_Report 2

TWA sample results were calculated to reflect an 8-hour time-weighted average. The TWA and STEL were compared to the following regulatory limits that are also in Table 1.0: Cal- OSHA Permissible Exposure Limit (PEL) time-weighted average (TWA), the Cal-OSHA action level (AL), the Cal-OSHA Short Term Exposure Limit (STEL), and recommended American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value-Ceiling (TLV-C). It is important to note that the ACGIH TLVs are only recommended guidelines used by industrial hygiene professionals and are not developed for use as legal standards, such as OSHA PELs. Personal Sampling The long-term personal sampling was collected for approximately fifty-six (56) minutes, during tasks directly involving work in the Cadaver Room and exposure to the embalming fluid (including formaldehyde and phenol). The short-term personal sample was collected during this same period of time, for approximately fifteen (15) minutes. Time weighted averages (TWAs) were calculated over an eight (8) hour work day. It is calculated by the following equation in Figure 1.0. Sample results were extrapolated to reflect an 8-hour time-weighted average shift, with zero concentrations assumed when working with the cadaver was not taking place, in order to more accurately compare with recognized occupational exposure limits. TWA T C T C... 1 2 2 8hr 1 Where T is the duration in hours of the exposure to a substance at the concentration C, and 8 hours is a work day. T C Figure 1.0 Calculating TWAs n n Results Formaldehyde: The long-term personal sample concentration exceeded the Cal-OSHA AL but was lower than Cal-OSHA PEL TWA. The short-term personal sample concentration exceeded the Cal-OSHA STEL and the recommended ACGIH TLV-C (STEL-C). Phenol: The long-term and short-term personal sample concentrations were lower than the Cal- OSHA PEL, NIOSH STELs, and recommended ACGIH TLV (TWA). A summary of the results and applicable exposure limits is presented below in Tables 1.0 and 2.0.

CITADEL PROJECT NO. 0069.1080.0 FORMALDEHYDE & PHENOL EXPOSURE MONITORING REPORT OCTOBER 2015 SAMPLING EVENT #1 SAN BERNARDINO COMMUNITY COLLEGE DISTRICT CRAFTON HILLS COLLEGE YUCAIPA, CALIFORNIA OCTOBER 14, 2015 5.0 RECOMMENDATIONS During the monitoring performed on September 24, 2015: Formaldehyde: The long-term personal sample concentration exceeded the Cal-OSHA AL but was lower than Cal-OSHA PEL TWA. The short-term personal sample concentration exceeded the Cal-OSHA STEL and the recommended ACGIH TLV-C (STEL-C). Citadel notes that ACGIH TLVs are only recommended exposure limits used by industrial hygiene professionals, and are not developed for use as legal standards (such as OSHA PELs). The TWA result that was higher than the Cal-OSHA AL indicates that the cadaver dissection activities within the Cadaver Room are subject to the sampling and monitoring requirements promulgated by the OSHA Formaldehyde standard (29 CFR 1910.1048). Exposure monitoring shall occur every six (6) months for formaldehyde. Phenol: The long-term personal sample concentration was lower than the Cal-OSHA PEL TWA and the recommended ACGIH TLV (TWA). The short-term personal sample concentration was lower than the NIOSH STEL. Citadel notes that ACGIH TLVs are only recommended exposure limits used by industrial hygiene professionals, and are not developed for use as legal standards (such as OSHA PELs). While these results indicate that the cadaver dissection activities within the Cadaver Room are not subject to the sampling and monitoring requirements promulgated by the OSHA Guidance for Phenol, Citadel recommends annual exposure monitoring for phenol given the lack of historical phenol exposure monitoring data. Based upon sample results, Citadel additionally recommends that the following: Continued implementation of existing engineering controls including isolation activation of the exhaust system during periods of formaldehyde and phenol use/exposure. Continued implementation of the existing safety programs, including (but not limited to): o Adhering to the policies and procedures described in CHC s Formaldehyde and Phenol Program and Chemical Hygiene Plan; o Providing, maintaining, and ensuring the employees don appropriate respiratory protection. The use of respirators shall be in accordance with the OSHA Respiratory Protection Standard 29 CFR.1910.134. Employees must also receive training and be medically approved and fit-tested prior to donning a respirator; o Providing, maintaining, and ensuring the employees don appropriate PPE; o Ensuring that employees receive initial and annual hazard communication and formaldehyde and phenol safety training; o Ensuring proper storage, handling, labeling, decontamination and disposal procedures for formaldehyde and phenol use are being followed. Continue providing medical surveillance and air monitoring, per the OSHA Formaldehyde standard (29 CFR 1910.1048) and OSHA Guidance for Phenol, on instructors who perform dissections in the Cadaver Room. o Based on the sample results, this shall include monitoring every six (6) months for formaldehyde and annual monitoring for phenol, or more often if employees experience signs or symptoms of respiratory or dermal conditions associated with the formaldehyde and phenol exposure. o Periodic monitoring for employees may be discontinued if results from two consecutive sampling periods (taken at least 7 days apart) show that employee 0069-1080-0_CHC_Sept-2015_Formaldehyde&Phenol_Exposure_ Monitoring_Report 5
