You are a worker for “Kean Industrial Safety Services”You were hired to do an asbestos and hexavalent chrome study at a factory that makes car brakes (Metallic Co)You tested two employees on 10/30/21 for both asbestos and hex chrome (don’t worry about volume of air tested, just amount over time)Meso Thelium – metal cutter in the pad room, 9am-5pmCad Mium – welder in the sheet metal area, 7:30am-5pmYou used personal air monitors and sent the filters to Galson for analysisThe results were:Meso Thelium – Asbestos = 12 fibers/cm3, Hex Chrome = not detectedCad Mium – Asbestos = not detected, Hex Chrome = 5micrograms/m3Write the report stating any exposure concerns, adding recommendations, and including any necessary paperwork (like chains of custody maybe…galsonlabs_coc_form_US_.pdf)

The PELs were adopted exposure limits at the inception of OSHA. OSHA sets enforceable permissible exposure limits (PEL) to protect workers against the health effects of exposure to hazardous substances. PELs are regulatory limits on the amount or concentration of a substance in the air. They may also contain a skin designation. OSHA PELs are based on an 8-hour time weighted average (TWA) exposure. Refer to OSHA Chemical Sampling Informaiton The Chemical Sampling Information pages present, in concise form, data on a large number of chemical substances that may be encountered in industrial hygiene investigations. It is intended as a basic reference for OSHA personnel. https://www.osha.gov/dts/chemicalsampling/toc/toc_chemsamp.html Assessing Exposure “C” = ceiling limit Level never to be exceeded during the work shift Protect from acute disease or health effects Air QuALITY mONITORING Carbon Monoxide Caused by incomplete combustion of any carbon source Natural gas, oil, coal, etc… Mostly by internal combustion engines in workplace Can cause long term brain, heart, and lung damage Permissible Exposure Limit (PEL) 35ppm as an 8-hour time-weighted average (TWA) Ceiling of 200ppm Nitrogen Dioxide Exposure is usually from ICE Indoor can be cigarette smoke or kerosene/butane burning Can also associated with the production of nitric acid for fertilizers Causes lung irritation Linked to, and can exacerbate, asthma OSHA Ceiling of 5ppm ACGIH Threshold Limit Value (TLV) TWA of 0.2ppm Volatile Organic Compounds (VOC) These are EVERYWHERE! Gasoline, diesel fuel, other petroleum-based products, carpets, paints, varnishes, glues, spot removers, and cleaners.

Exposure groups are classified relative to the OSHA Permissible Exposure Limit (PEL) adjusted for the length of the work shift. 1.1.1 Average Noise Level Equals or Exceeds 88.4 dB-A Monitoring indicated that the following noise exposures equaled or exceeded the 10 hour OSHA Permissible Exposure Limit for noise (5-dB exchange rate) is calculated at 88.4 dB-A: No findings in this exposure category. 1.1.2 Average Noise Exposure between 83.4 dB-A and 88.4 dB-A Monitoring indicated that the following noise exposures were within the OSHA Permissible Exposure Limit for noise, but equaled or exceeded 50% of the OSHA permitted dose, for the length of the work shift, requiring participation in a Hearing Conservation Program: No findings in this exposure category. 1.1.3 Areas with Noise Levels Above 85 dB-A Building Area/Location Sound Level in dB-A Main Building Inside the Autoclave Room 89.9 Main Building Air Compressor/Basement 84-91.6 Main Building Tiller/Basement 84.8 Main Building Med Clean – Inside Curtain 89.3 Main Building Med Clean – Gap in Curtain 85.5 1.2 Chemical Exposures In some cases, an individual chemical may have several conflicting Occupational Exposure Limits (OEL) issued by different regulatory agencies and scientific organizations. For the purpose of these tables, exposures are categorized based upon the most protective of the major OEL (Federal, OSHA, or ACGIH), adjusted for the length of the work shift. These findings are described in detail in the Discussion section of this report. For individual exposure information, see the data tables in the Sampling/Monitoring Data section. 1.2.1 Occupational Exposures That May Equal or Exceed an OEL No findings in this exposure category. 2.0 INTRODUCTION On January 25, 2020, Mr. Joseph Sarnoski, an Environmental Consultant with Green Environmental, Inc. (GEI) performed air sampling and noise monitoring for Corporation, Inc. at two locations of 123 Fourth St, in Sometown, NJ (Main Building) and 234 Fifth Way in Sometown, NJ; subsequently on February 5, 2020 performed passive sampling inside Corporation, Inc.’s Main Building. This survey was conducted to assess personnel exposures to formaldehyde, ethanol, ethanolamine, and Spor-Klenz (hydrogen peroxide and acetic acid). Ms. Environmental Person, a senior Environment, Health, and Safety Specialist, with Corporation, Inc. provided assistance and guidance throughout both facilities, as well as background information. Corporation, Inc. is considered a global leader in medical technology; they serve patients and partner with medical professionals in 120 countries. The plant location in Sometown consists of offices, laboratories, and a warehouse for manufacturing and distribution. The company employs approximately 200 full-time workers operating Monday to Friday working two shifts that start at 6:00 A.M. and finish at 4:00 P.M; and starting at 3:00 P.M. and finish at 11:00 P.M. The results of sampling and monitoring performed during this survey are contained in data tables, to be found in the Results section which follows Materials and Sampling Methods section. 3.0 MATERIALS AND SAMPLING METHODS An assessment was made
