Action level. An airborne concentration of benzene of 0.5 parts per million (ppm) calculated as an eight-hour time-weighted average. Authorized personnel. Individuals specifically permitted by the employer to enter the exposure control area to perform necessary duties, or to observe employee exposure evaluations as a designated representative. Benzene. Liquid benzene, benzene vapor, and benzene in liquid mixtures and the vapors released by these liquids. The chemical abstract service (CAS) registry number for benzene is 71-43-2. CAS numbers are internationally recognized and used on safety data sheets (SDSs) and other documents to identify substances. For more information, see http://www.cas.org/about. Breathing zone. The space around and in front of an employee's nose and mouth, forming a hemisphere with a 6- to 9-inch radius. Bulk wholesale storage facility. Any bulk terminal or bulk plant where fuel is stored before its delivery to wholesale customers. Container. Any container, except for pipes or piping systems, that contains benzene. It can be any of the following: Barrel; Bottle; Can; Cylinder; Drum; Reaction vessel; Storage tank. Day. Any part of a calendar day. Designated representative. Any of the following: Any individual or organization to which an employee gives written authorization; A recognized or certified collective bargaining agent without regard to written employee authorization; or The legal representative of a deceased or legally incapacitated employee. Emergency. Any event that could or does result in the unexpected significant release of benzene. Examples of emergencies include equipment failure, container rupture, or control equipment failure. Exposure. The contact an employee has with benzene, whether or not protection is provided by respirators or other personal protective equipment (PPE). Contact can occur through various routes of entry such as inhalation, ingestion, skin contact, or skin absorption. Licensed health care professional (LHCP). An individual whose legally permitted scope of practice allows him or her to provide some or all of the health care services required for medical evaluations. Page 1 Chapter 296-849 WAC Benzen _________________________________________________________________________________________________________ Permissible exposure limits (PELs). PELs are employee exposures to toxic substances or harmful physical agents that must not be exceeded. PELs are also specified in various WISHA rules found in other chapters. The PELs for benzene are the: Eight-hour time-weighted average (TWA8) of 1 part per million (ppm); and Fifteen-minute short-term exposure limit (STEL) of 5 ppm. Short-term exposure limit (STEL). An exposure limit averaged over a fifteen-minute period that must not be exceeded during any part of an employee's workday. Time-weighted average (TWA8). An exposure limit averaged over an eight-hour period that must not be exceeded during an employee's workday. Vapor control systems. Equipment that controls the vapor displaced when chemicals are loaded and unloaded from truck or storage tanks. It also processes or balances the vapor back into the truck or storage tanks. Page 2 Chapter 296-849 WAC Benzen _________________________________________________________________________________________________________ WAC 296-849-100 Scope. This chapter applies to all occupational exposure to benzene. Definition: Exposure. The contact an employee has with benzene, whether or not protection is provided by respirators or other personal protective equipment (PPE). Exposure can occur through various routes of entry such as inhalation, ingestion, skin contact, or skin absorption. EXEMPTIONS: This chapter does not apply to any of the following: Liquids, vapors, mixtures in containers or pipelines, and gas in natural gas processing plants when benzene content is 0.1% or less. Gasoline and other fuels containing benzene once they leave the final bulk wholesale facility and are being: – Transported; – Sold; – Distributed; – Stored; – Dispensed either: . Outdoors; or .

Oil and gas drilling, production, and servicing operations. Solid materials that contain only trace amounts of benzene. Coke ovens. All requirements in this chapter will not apply to every workplace with an occupational exposure. The following will show you which requirements apply to your workplace. Page 3 Chapter 296-849 WAC Benzen _________________________________________________________________________________________________________ Step 1: If any of your work tasks are listed in Table 1, follow Table 1. Go to Step 2a if you have additional work tasks or other exposures that are not covered in Table 1. Table 1 Requirements that Apply to Specific Tasks If employees do any of the following: Then the only requirements in this chapter that apply to those tasks are: Load and unload benzene at bulk storage The labeling requirement found in facilities that use vapor control systems for all Preventive practices, WAC 296- loading and unloading operations. 849-11010.

  • Retention Indices for Frequently Reported Compounds of Plant Essential Oils
    Retention Indices for Frequently Reported Compounds of Plant Essential Oils V. I. Babushok,a) P. J. Linstrom, and I. G. Zenkevichb) National Institute of Standards and Technology, Gaithersburg, Maryland 20899, USA (Received 1 August 2011; accepted 27 September 2011; published online 29 November 2011) Gas chromatographic retention indices were evaluated for 505 frequently reported plant essential oil components using a large retention index database. Retention data are presented for three types of commonly used stationary phases: dimethyl silicone (nonpolar), dimethyl sili- cone with 5% phenyl groups (slightly polar), and polyethylene glycol (polar) stationary phases. The evaluations are based on the treatment of multiple measurements with the number of data records ranging from about 5 to 800 per compound. Data analysis was limited to temperature programmed conditions. The data reported include the average and median values of retention index with standard deviations and confidence intervals.

    Finding Physical Properties and Spectral Diagrams for a Known Chemistry Substance: Quick Tips for Chemistry 130 Library Guide: http://libguides.stanford.edu/chem130 Grace Baysinger [email protected] Swain Chemistry and Chemical Engineering Librarian What is a CAS Registry Number? ◦ It is a unique numeric identifier that has no chemical significance. ◦ Designates only one substance. A different CAS RN is assigned for charged, isotopically labeled, or stereoisomers of a substance. ◦ A CAS Registry Number can contain up to 10 digits, divided by hyphens into three parts. Example: 58- 08-2 is the CAS RN for caffeine. ◦ About 12,000 new substances are added to the CAS Registry each day. For more information, see: http://www.cas.org/expertise/cascontent/registry/regsys.html#q2 Using CAS Registry Numbers in Database Searches CAS RNs are a quick way to search for a specific chemical substance in different chemistry databases.
