'^ CH/W-000681 FORWARD This publication has been developed for Champlin employees who may have occasion to refer to Material Safety Data Sheets (MSDSs) in the course of their work activities. The information contained in this guide should be equally useful to the Champlin customer, the contractor, the outside physician or others concerned with protection of people, property and the envi ronment. The information is not confidential or proprietary, and may be shared freely with such outside associates and contacts who have a need for this information. It must be understood that this Guide is intended as a reference, and that much of the information is in condensed form. The MSDS itself may not be sufficient information for those implementing specific safe work practices or purchasing proper protective equipment. The MSDS is intended to alert the user to the potential hazards, and the basic principles or methods to be considered, for the safe use and handling of the material. Other, more detailed sources of information should be consulted when more data is needed. The purpose of the Material Safety Data Sheet (MSDS) is to provide readily accessible information regarding the characteristics of chemical products and intermediate materials (this includes catalysts and chemicals) and the appropriate safe work habits for each. Since all conditions of material handling cannot be covered, conservative measures are generally described. The MSDS is a standardized format, organized into nine sections. The sections provide information on each material, such as names, ingredients, health information, occupational exposure limits, emergency and first aid procedures, physical data, fire and ex plosion hazards, reactivity, employee protection, transportation requirements and other regulatory controls.

The temperature at which a liquid changes to a vapor state, at a given pressure; usually in degrees Fahrenheit CF) at sea level pressure of 760 millimeters (mm) of mercury (Hg) . For mixtures, the initial boiling point or the boiling range may be given. Vapor Pressure. The pressure exerted by a saturated vapor above its own liquid in a closed container, usually stated in millimeters (mm) of mercury (Hg) at 68 degrees Fahrenheit (F) or 20 degrees Celsius (C). Vapor Density. The weight of a vapor or gas compared to the weight of an equal volume of air; and expression of the density of the vapor or gas. Materials lighter than air have vapor densities less than 1.0 (examples: acetylene, methane, hydrogen). Materials heavier than air (examples: propane, hydrogen sulfide, ethane, butane, chlorine, sulfur dioxide) have vapor densities greater than 1.0. All vapors and gases will mix with air, but the lighter materials will tend to rise and dissipate (unless confined). Heavier vapors and gases are likely to concentrate in low places-- along or under floors, in swamps, sewers and manholes, in trenches and ditches--where they may create fire or health hazards. 12/9/85 7 CH/W-000688 FLAS-M POINT extinguishing yrni* en.

The lowest temperature in degrees Fahrenheit (F), at which a liquid will give off enough flammable vapor to ignite. Since flash points vary according to how they are obtained, the method used must be listed. The methods used most extensively include: Tag Closed Cup (TCC); Pensky-Martens Closed Cup (PMCC) and Setaflash (SETA). Auto Ignition. The auto-ignition temperature of a substance whether solid, liquid or gaseous is the lowest temperature required to initiate or cause, self-sustained combustion in the absence of a spark or flame. This temperature varies considerably, depending upon the nature, size and shape of the igniting surface or con tainers and other factors. The auto-ignition temperature of a solid is influenced by its physical condition and the rate of heat ing. Vapors of several common flammable liquids can be ignited under favorable conditions by metal heated to temperatures as low as 500 F. The vapor of carbon disulfide can be so ignited at a temperature of about 257F. Flammable Limits. The range of concentrations over which a flammable vapor mixed with proper proportions of air will flash if an ignition source is present. 12/9/85 9 CH/W-000690 SECTION V-HEALTH HAZARD DATA THRESHOLD LIMIT VALUE ___ (Ammonia Vapor) 50ppm AIR SAMPLING AND analysis EFFECTS OF OVAEXOSU*E Irritation of eyes, upper respiratory tract and skin FIRST AID TREATMENT a. inhalation: remove to fresh air, apply artificial respiration if not1 breathing and get medical attention b skin contact: flush with water c eye contact: flush with water for at least 15 minutes, get medical attention d. ingestion: get medical attention SECTION V HEALTH HAZARD DATA Threshold Limit Value.

Avoid contact with liquid. Disposal should be in accordance with WASTE DISPOSAL METHOD local, state and federal regulations SECTION VII SPILL OR LEAK PROCEDURE Control of Leaks or Spills. This should include the methods to be used to control and clean up spills and leaks, i.e., applicable precautions such as: avoiding breathing of gases or vapors; contact with liquids and solids? removing sources of ignition, etc. It should also list the need (if any) for special equipment to be used for clean up, such as glass or plastic scoops, etc. Waste Disposal Methods. Should describe the acceptable, as well as prohibited methods for disposing of spilled solids or liquids, such as flushing with water, returning to container, burning, etc. Should also alert the user of any potential danger to the environ ment such as effects on general population, crops, water supplies, etc. 12/9/85 13 CH/W-000694 SECTION IX SPECIAL PRECAUTIONS Handling and Storage Precaution. Any additional or special pre cautions not addressed elsewhere in the MSDS should be listed here. This may include such items as handling or storing to avoid reac tion hazards, safe storage life of the product in relation to reactivity, special packaging requirements, temperature control, etc. Other Precautions. A catch-all category for any other general pre cautions that should be taken. 12/9/85 15 CH/W-000696 GLOSSARY OF COMMON MSDS TERMS Asphyxiant - a vapor or gas which can cause unconsciousness or death by suffocation (lack of oxygen). Most simple asphyxiants are harmful to the body only when they become so concentrated that they reduce oxygen in the air (normally about 21 percent) to dangerous levels (16 per cent or lower). Asphyxiation is one of the principal po tential hazards of working in confined spaces. ASTM - American Society for Testing and Materials; voluntary membership organization with members from broad spectrum of individuals, agencies and industries concerned with materials. The world's largest source of voluntary consensus standards for materials, products, systems and services, ASTM is a resource for sampling and testing methods, health and safety aspects of biological agents and chemicals. B Boiling Point - The temperature at which a liquid changes to a vapor state, at a given pressure; usually expressed in degrees Fahrenheit at sea level pressure (760 mmHg, or one atmosphere). For mixtures, the initial boiling point or the boiling range may be given. Flammable materials with low boiling points generally present special fire hazards. Some approximate boiling points: Propane Anhydrous Ammonia Butane Gasoline Allyl Chloride Ethylene Glycol -4 4 F -28 F 31 F 100 F 113 F 387 F BOM, or BuMines- Bureau <?f Mines of the U.S. Department of Interior.

DOT- U.S. Department of Transportation; regulates transportation of chemicals and other substances, to aid in the protection of the public as well as fire, law enforcement and other emergency response personnel, particularly when transporta tion incidents occur involving hazardous materials. Detailed DOT classification lists specify appropriate warnings--such as Oxidizing Agent or Flammable Liquid--which must be used for various substances. 12/9/85 21 ch/vj-o00702 GLOSSARY OF COMMON MSDS TERMS FIFRA - Federal Insecticide, Fungicide and Rodenticide Act; re gulations administered.by EPA under this act require that certain useful poisons, such as chemical pesticides, sold to the public contain labels that carry health hazard warnings to protect users. Flash Point - The temperature at which a liquid will give off enough flammable vapor to ignite. There are several flash point test methods, and flash points may vary for the same material depending on the method used, so the test method is indicated when the flash point is given (150 PMCC, 200 TCC, etc.). Flammable - A "flammable liquid" is defined by NFPA and DOT as a liquid with a flash point below 100F (37.8C). Solids that will ignite readily or are liable to cause fires under or dinary conditions of transportation through friction or re tained heat from manufacturing or processing, and which burn so vigorously and persistently as to create a serious transportation hazard are classified by DOT as "flammable solids." Also see "combustible."

OSHA - Occupational Safety and Health Administration of the U.S. Department of Labor; federal agency with safety and health regulatory and enforcement authorities for most U.S. in dustry and business. Also see "MSHA." Oxidation - In a literal sense, oxidation is a reaction in which a substance combines with oxygen provided by an oxidizer or oxidizing agent (see definitions below). In a broader sense, based on modern atomic theory, science today defines oxidation as a reaction--brought about by an oxidizing agent in which atoms, molecules or ions lose electrons. In this broader sense, an oxidation reaction may occur even when oxygen is not present. However it may be defined, an oxi dation reaction is always accompanied by an offsetting (balancing) reduction reaction in which (1) oxygen is re moved from a compound or (2) atoms, molecules or ions gain electrons. 12/9/85 29 CH/W-000710 GLOSSARY OF COMMON MSDS TERMS Polymerization - A chemical reaction in which one or more small molecules combine to form larger molecules. A hazardous polymerization is a reaction which takes place at a rate which releases large amounts of energy. If hazardous polymerization can occur with a given material, the MSDS usually will list conditions which could start the reaction and--since the material usually contains a polymerization inhibitor--the expected time period before the inhibitor is used up. ppb psi Parts per million; a unit for measuring the concentration of a gas or vapor in air--parts (by volume) of the gas or vapor in a million parts of air. Also used to indicate the concentration of a particular substance in a liquid, gas or solid.

Usually used to express measurements of extremely low concentrations of unusually toxic gases or vapors. Also used to indicate the concen tration of a particular substance in a liquid, gas or solid. Pounds per square inch; for MSDS purposes, a unit for measuring the pressure a material exerts on the walls of a confining vessel or enclosure. For technical accuracy, pressure must be expressed as psiq (pounds per square inch gauge) or psia (pounds per square inch absolute; that is; gauge pressure plus sea level atmospheric pressure, or psig plus about 14.7 pounds per square inch). Also see "mmHg". 12/9/85 31 CH/W-000712 GLOSSARY OF COMMON MSPS TERMS ----------------------------S------------------------------- Sensitizer - A chemical that causes a substantial proportion of exposed people or animals to develop an allergic reaction in normal tissue after repeated exposure to the chemical. Seta - Setaflash Closed Tester; a flash point test method. "Skin" - A notation, sometimes used with PEL or TLV exposure data; indicates that the stated substance may be absorbed by the skin, mucous membranes and eyes--either airborne or by direct contact--and that this additional exposure must be considered part of the total exposure to avoid exceeding the PEL or TLV for that substance. Skin Sensitizer - See "Sensitizer". Skin Toxicity - See "Dermal Toxicity". Solubility in water - A term expressing the percentage of a material (by weight) that will dissolve in water at ambient 1 temperature. Solubility information can be useful in deter mining spill clean up methods and fire-extinguishing agents and methods for a material. Terms used to express solu bility are: negligible slight moderate appreciable complete Less than 0.1 per cent 0.1 to 1.0 per cent 1 to 10 per cent more than 10 per cent soluble in all proportions SO* - Oxides of sulfur; undesirable air pollutants. SOx emis sions are regulated by EPA under the Clean Air Act. Species - A biological type; on MSDSs, species refers to the test animals--usually rats, mice or rabbits--which were used to obtain the toxicity test data reported. 12/9/85 33 CH/W-000714 i GLOSSARY OF COMMON MSDS TERMS TLV- Threshold Limit Value; a term used by ACGIH to express the airborne concentration of a material to which nearly all persons can be exposed day after day, without adverse effects. ACGIH expresses TLV's in three ways: TLV-TWA: the allowable Time Weighted Average concen tration for a normal 8-hour work day and 40-hour work week. TLV-STEL: the Short-Term Exposure Limit, or maximum concentration for a continuous 15-minute exposure period (maximum of four such periods per day, with at least 60 minutes between exposure periods, and provided that the daily TLV-TWA is not exceeded). TLV--C: the Ceiling Exposure Limit--the concentration that should not be exceeded even instantaneously. Also see "Skin" in the Glossary relative to TLV's. TOC - Tag (Tagliabue) Open Cup - A flash point test method. Toxic - A chemical falling within any of the following categories: a) A chemical that has a median lethal dose (Lr>50) of more than 50 milligrams per kilogram, but not more than 500 milligrams per kilogram of body weight when administered orally to albino rats weighing between 200 and 300 grams each. b) A chemical that has a median lethal dose (LDso) of more than 200 milligrams per kilogram but not more than 1,000 milligrams per kilogram of body weight when admin istered by continuous contact for 24 hours (or less if death occurs within 24 hours) with the bare skin of of albino rabbits weighing between two and three kilograms each. c) A chemical that has median lethal concentration (LC50) in air of more than 200 parts per million but not more than 2000 parts per million by volume of gas or vapor, or more than two milligrams per liter, but not more than 20 milligrams per liter of mist, fume, or dust, when ad ministered by continuous inhalation for one hour (or less if death occurs within one hour) to albino rats weighing between 200 and 300 grams each. 12/9/85 CH/W-000716 GLOSSARY OF COMMON MSDS TERMS ----------------------------V------------------------------- Vapor Density - The weight of a vapor or gas compared to the weight of an equal volume of air; an expression of the density of the vapor or gas. Materials lighter than air have vapor densities less than 1.0 (examples: acetylene, methane, hydrogen). Materials heavier than air (examples: propane, hydrogen sulfide, ethane, butane, chlorine, sulfur dioxide) have vapor densities greater than 1.0. All vapors and gases will mix with air, but the lighter materials will tend to rise and dissipate (unless confined) . Heavier vapors and gases are likely to concentrate in low places-along or under floors, in swamps, sewers and manholes, in trenches and ditches--where they may create fire or health hazards. Vapor Pressure - The pressure exerted by a saturated vapor above its own liquid in a closed container. When quality control tests are performed on products the test temperature is usually 100F. and the vapor pressure is expressed as pounds per square inch (psig or psia)-- but vapor pressures reported on MSDS's are in millimeters of mercury (mmHg) at 68F. (20C.), unless stated other wise. Three facts are important to remember: 1. Vapor pressure of a substance at 100F will always be higher than the vapor pressure of the substance at 68F. (20C.) . 2. Vapor pressures reported on MSDS1s in mmHg are usually very low pressures; 760 mmHg is equivalent to 14.7 pounds per square inch. 3. The lower the boiling point of a substance, the higher its vapor pressure. Ventilation - See "general exhaust", "local exhaust" and "mechani cal exhaust". 12/9/85 37 CH/W-000718 CHG 00980 CH/W-000678
