Question
1. Physical praperties of each chemical including the physical state (gas, liquid, solid) at room temperature (25 degrees C78 degrees F) 2. At least two processes where the chemical is used in industry 3. The OSHA PEL for each chemical lIf the PEL is siven in ppm enter the units in ppm),. 4. The method used by OSHA for callecting an air sample to determine an employee exposure for each chemical. Make sure you include a description of the collecting medium, the recommended flowrate or range of flowrates, and the recommended minimum and/or maximum sample volume or sampling time 5. The analytical method used to analyze the sample including the limit of detection (Include an OSHA reference number for the method). You must include the units for the limit of detection Chemicals (Note that the CAS number is shown in parentheses for positive identification of the chemical): Acrolein (107-02-8), n-hexane (110-54-3), cobalt (7440-48-4), elemental mercury (7439-97- 6), methyl ethyl ketone (78-93-3), sulfuric acid mist (7664-93-9), trinitrotoluene (118-96-7), toluene diisocyanate (26471-62-5), perchoroethylene (127-18-4), triethylamine (121-44-8), vinyl chloride (75-01 4) and carbon monoxide (630-08-0 Helpful websites

2. Processes:
3. OSHO PEL*:
OSHA Permissible Exposure Limit (PEL):
American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV): 0.1 ppm, 0.23 mg/m3 Ceiling; Skin; Appendix A4 - Not Classifiable as a Human Carcinogen
National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL): 0.1 ppm, 0.25 mg/m3 TWA; 0.3 ppm, 0.8 mg/m3 STEL;
4 & 5. Methods used by OSHA: Two different ways are used by OSHA
