safe handling and storage of styrene monomer
Th e amount of i nhibitor required to a chieve the assured inhibition level can also be calculated using the following formula: cc s of TBC concentrate = lbs. Styrenecontaining vessels should be protecte d from external sources of heat. (To comply with OSHA s Hazard Communication Standard 29CFR 1910.1200/ANSI z400. 4 to 5 days 6 months 110 F 8 to 12 days Less than 24 hours Less than 30 days Table 2A Suggested Monitoring Schedule for Styrene Bulk Storage Monomer Temperature Daily Table 2B Suggested Testing Schedule for Styrene Bulk Storage Monomer Temperature, degrees F 80 or higher Below 70 Frequency Weekly Bi-weekly Monthly Polymer Inhibitor Color Appearance Aldehydes Peroxides Key Properties ASTM D2121 ASTM D4590 ASTM D5386 or D1209 Visual ASTM D2119 ASTM D2340 JULY 2011 (PRINT) 15, 21 Table 2C Suggested Inspection Schedule for Styrene Bulk Storage Inspection Air Vents Vacuum pressure relief Flame arrester Foam reservoir should be inspected for polymer Tank interior Frequency Quarterly Every 3 years, if coated Annually, if uncoated OXYGEN REQUIREMENTS The problem presented by air i s complex. Polyester, Nomex, Rayon an d Nylon fiber filters are compatible with styrene. Eng. Small trial blend s should be made to determine the feasibility of this approach. Acrylic Adhesives. JULY 2011 (PRINT) 19, 25 Color in styrene mo nomer can be reduced to acceptable limits by: 1. D5386 Color of Liquids using Tristimulus Colorimetry 10. SAFETY DATA SHEET According to 1907/2006/EC, Article 31 Styrene Monomer Section 1: Identification of the substance/mixture and of the company / undertaking 1.1 Product Identifier Product Name Styrene Monomer Other Names Phenylethylene CAS No. DHMD102. The latter arrangements should adhere to the same distribution Solution s of TBC may be obtained by contacting your Americas Styrenics LLC representative or through your purchasing agent. Section Includes: 1. TBC may oxidize to form highly-colored reaction products. This type of co nstruction simplifies the i nstallation of linings and permits rapid drainage of uninhibited condensed vapors back into the liquid monomer, thus reducing the polymer and stalactite problem. Gaskets made of rubber or oth er styrene-soluble materials should be avoided. Purging all l ines with nitrogen prior to transfer of p roduct reduces risk of flash fires. Determinations of inhibitor content, oxygen level in th e vapor space, polymer content, and mo nomer temperature should be made on a routine basis (details are provided in Part 4). Contents . Monomer vapors above the liquid level in the tank are uninhibited.

General Vaporizers are constructed in numerous designs and operated in many modes. 1.2, CHAPTER 9 SAMPLERS AND SAMPLING PROCEDURES GENERAL A sample is a small portion of a substance used to inspect or to determine the quality of the substance. Do not leave styrene in b locked lines because thermal expansion could damage valves and seals and the monomer is more likely to become oxygen and i nhibitor depleted. Signs and symptoms of styrene exposure and action to be ta ken and medical conditions aggravated by exposure to styrene. O-RINGS Viton, Teflon, Fluoul, or their equivalents are recommended. DRUMS Drums of st yrene monomer should not be permitted to stand in the sun for more than a short period of time. HANDLING RUNAWAY POLYMERIZATIONS The action to take will d epend on how far the runaway has proceeded.

The relatively small quantities of TBC required to raise the inhibitor level in sto red monomer can most easily be added by u sing an 85% TBC/15% Methanol blend or a concentrated stock solution in the monomer or other solvent. Tank linings have proven quite succe ssful in controlling or reducing polymer and stalactite formation. Bull., 1985, (065), p. 25].
