Laboratory Safety Manual Laboratory Safety Manual THE UNIVERSITY OF TEXAS AT AUSTIN OFFICE OF ENVIRONMENTAL HEALTH AND SAFETY NOVEMBER 1996 Note To Users Of This Laboratory Safety Manual The Office of Environmental Health and Safety (OEHS) Hazardous Materials Division has prepared this manual to ensure safe practices in laboratories. The health and safety policy of The University is to take every reasonable precaution to protect the health and safety of faculty, staff, students, and the public. Mandatory safety standards, as interpreted by the requirements and policies stated in this manual and its supplements apply to faculty, staff, researchers, and students engaged in laboratory operations utilizing chemical products and in performing common laboratory procedures. This manual includes information concerning safe laboratory practices, the use of personal protective equipment, emergency procedures, use and storage of chemicals, and the proper methods of waste disposal. This manual covers safety practices for labs in the biological sciences, incorporating a full description of the various biosafety levels and procedures unique to each. This manual also covers hazard communication and incident response. This information is intended to help those in the laboratory to minimize hazards to themselves and their colleagues. In view of the wide variety of chemical products handled in laboratories, it should not be assumed that the precautions and requirements stated in this manual are all-inclusive. Faculty, researchers, and students are expected to learn about the hazards of chemical products before handling them. It is expected that the local departmental Chemical Hygiene Officers and Principal Investigators will append to this manual any supplementary information pertinent to their specific areas. Throughout this manual the terms “employee”, “laboratory worker”, and “laboratory personnel” are used interchangeably and are intended to include students working in a laboratory, unless the context indicates otherwise. Please contact the OEHS Hazardous Materials Division at 471-3511 for more information or for assistance. TABLE OF CONTENTS A.

Seaver Lewis Research Center SUMMARY The solubilities of several substances in liquid fluorine have been deter- mined between 68' and 83' K by vapor-pressure measurements. These experimental data, as well as a summary of literature data on solutions of solids in cryo- genic liquids, are presented and compared with solubilities calculated by as- suming regular solutions. Experimental and calculated values for the solubili- ties of carbon tetrafluoride, perfluorethane, and perchloryl fluoride in liquid fluorine show close agreement, while the solubilities of krypton and xenon in fluorine show considerable deviation from calculated values. Little of the literature data agrees with the calculated solubilities. Deviations from cal- culated values are discussed. INTRODUCTION Only a limited amount of past work has been concerned with the prediction of the solubilities of solids in cryogenic liquids. Information on solutions in liquid fluorine is essentially nonexistent, and in the case of carbon tetra- fluoride the solubility data that are available (ref. 1) appear to be in con- siderable error. This lack of information, together with the importance of cryogenic liquids in space applications and the possible use of fluorine as a rocket propellant, prompted the present investigation.
