5 Safety Data Sheets (SDS) SDS Learning Module Participant Guide Description and Estimated Time to Complete Being able to locate and interpret a Safety Data Sheet (SDS) is important to anyone involved in the fabrication of MEMS (microelectromechanical systems) and any micro or nano-sized devices. Micro and nanotechnology fabrication require several hazardous chemicals. SDSs are available for each chemical used in these facilities. A SDS explains the potential hazards of a chemical. It also provides information necessary to protect you from unnecessary exposure as well as other valuable safety information. You should always study a chemical's SDS prior to working around or handling a chemical. The purpose of this learning module is to provide information on the requirements and content of Safety Data Sheets (SDS), how to locate a SDS, and how to interpret a SDS. Activities allow students to demonstrate their ability to find a specific SDS and to extract and interpret important safety information from the SDS. This unit provides content information about Safety Data Sheets (SDS), data contained within a SDS, and interpretation of that data. This information will assist in extracting specifics from a SDS and interpreting the information. This unit has been updated to the new OSHA Hazard Communication Standard 29CFR [ that became effective May 25, This standard was revised to better align the United States with the UN Globally Harmonized System of Classification and Labeling of Chemicals (GHS), Revision 3. It would be helpful to download two different SDS's prior to beginning this lesson. Suggestion: Isopropyl Alcohol and Chlorine. To download a specific SDS, just do a search for Isopropyl Alcohol SDS. Your search will return many websites to choose from. Laboratories and suppliers are the best sources. Estimated Time to Complete Allow at least 15 minutes Southwest Center for Microsystems Education (SCME) Page 1 of 10 Saf_HazMat_PK30_PG_January2017.docx SDS PK

6 Introduction In order to work safely in a laboratory or manufacturing facility in which hazardous materials are found, you must understand the purpose of a SDS and how to extract information about a chemical. The knowledge in this unit will provide information about a SDS that can be used to investigate any chemical. Pouring Acid under a fume hood A Safety Data Sheet (SDS) is a document that provides vital information about a chemical for all those that use it, transport it, store it, or work around it in any manner. A SDS is required by Federal law to be prepared for each chemical imported or produced in this country. It is the chemical manufacturer's responsibility to supply a SDS with each chemical it sells. It is the employer's responsibility to maintain an updated SDS for all chemicals on the premises, and to make them readily accessible to all employees. This responsibility extends to chemicals such as Super Glue, Elmers, and Scotch Guard. If such chemicals are on the premises, a SDS must be available. A SDS contains information on the hazards associated with a particular chemical, handling information, emergency procedures for spills or human contact, and data associated with its flammability and reactivity. Before storing, handling or working with a chemical in any manner, you should become familiar with the information provided in the chemical's SDS. OSHA s* (HazCom standard (29 CFR )[ identifies all 16 elements that must be on a SDS. Those elements are briefly discussed in this unit. *U.S. Occupational Safety and Health Administration (OSHA), an agency of the U.S. Department of Labor. Learning Module Objectives Interpret the contents of at least three SDSs for specific chemicals. Identify the applications of at least three chemicals in microtechnology fabrication processes. Define the basic terms used by a SDS to describe a chemical s hazards Southwest Center for Microsystems Education (SCME) Page 2 of 10

7 Dependencies A basic understanding of Hazardous Materials terminology would enhance learning. (See SCME's Hazardous Materials I and II) SDS Requirements BEFORE storing, handling or working with a chemical in any manner, you should become familiar with the information provided in that chemical's SDS. You should always know how to properly handle a chemical, how to prevent exposure, how to recognize the symptoms of overexposure, and the emergency procedure for overexposure. It is the employer s responsibility as well as the employee s to ensure that all safety precautions are used and all safety procedures are followed. SAFETY FIRST!

8 SDS Terminology Much of the terminology found in a SDS is related to the hazardous characteristics of a chemical. This includes terms such as toxicity, flashpoint, and reactivity. You will also find terminology related to regulations such as the TLV or Threshold Limit Values for toxicity. There are several SDS glossaries that provide definitions for most of these terms. The SDS Hyperglossary ( ) is a great reference. As we go through the information and terminology of a SDS, locate the information on each of your SDS's. Chemical Information / Composition / Exposure Controls The following terms / acronyms are different ways of identifying the chemical on the SDS. Not all terms are used in a SDS. Product Name - The manufacturer's name for the chemical or the chemical mixture. In some cases the "product name" is protected as a trademark. An example is Clorox. Clorox is a trademark for chlorine bleach manufactured by the Clorox Company. Chemical Name - The name of the chemical (the element, chemical compound or mixture). The scientific designation of a chemical that clearly identifies the chemical for the purpose of conducting a hazardous evaluation. The chemical name in this label is "Boron Trichloride". CAS # - The Chemical Abstract Service registry number which identifies the chemical. What is the CAS for BCL3? EPA # - The number assigned to the chemical for regulatory purposes by the Environmental Protection Agency (EPA). Generic Name, Synonyms - Other names the chemical is commonly known by. For example, chlorine bleach is also referred to as bleach. TLV or Threshold Limit Value - The airborne concentration of a chemical. A TLV is the concentration in ppm (parts per million) under which workers may be repeatedly exposed day after day without adverse effects. TLV's are revised yearly by the American Conference of Governmental Industrial Hygienists'. PEL or permissible exposure limit - Similar to TLV, but is determined by OSHA. Find this information within your SDS's. Southwest Center for Microsystems Education (SCME) Page 4 of 10

9 Classification and Mixture Hazard Classification - The nature and degree of the predominant hazard associated with the chemical. Such classifications include flammable, poison, corrosive, oxidizer, combustible, and reactive. Material and Percentage of Mixture - The chemical ingredients by their percent (for chemicals that are mixtures). All ingredients that have been determined to be physical or health hazards and comprise 1.0% or more of the composition must be listed. Chemicals that have been identified as carcinogens must be identified if the concentrations are 0.1% or greater. Physical Data Boiling Point - The temperature at which the vapor pressure of a liquid equals atmospheric pressure or at which the liquid changes to a vapor. Freezing Point - The temperature at which the liquid takes on a solid state. Evaporation Rate - The rate at which a material converts to a vapor at any given temperature and pressure. Odor and Appearance What it looks like (e.g., color, transparency) and what it smells like (e.g., odorless, moldy, pungent). Percent Volatile by volume - The percent of a material (by volume) that will evaporate at an ambient temperature of 70 F. Surface area, length of time, and other factors influence percent volatile; no standard procedures exist. Solubility in Water - The solubility of a product by weight in water at ambient temperature as expressed in the following terms: Negligible - less than -0.1% Slight % Moderate 1.0 to 10% Appreciable - More than 10% Complete - 100% Solubility information is useful in determining effective fire extinguishing methods and spill cleanup procedures. Southwest Center for Microsystems Education (SCME) Page 5 of 10

10 Specific Gravity (Water = 1) - The ratio of the weight of a volume of material to the weight of an equal volume of water. How heavy the material is in comparison to water. A ratio of less than 1 means the material is lighter than water and will float on the surface. Most flammables are less than one. Vapor Pressure - The pressure of a saturated vapor above a liquid, in millimeters of 20 C. Vapor Density - The relative density or weight of a vapor or gas compared to an equal amount of air. Air is rated at 1.0. Therefore, a number greater than 1.0 indicates a vapor or gas heavier than air, and vice versa. Concentrated vapors that are heavier than air can accumulate in low places such as along floors and pits. They can also settle in the lower lung. Physical Data for BCL3 Find this information within your SDS's. Fire and Explosion Hazard Data / Fire-Fighting Measures Flammability Data - A flammable, combustible, pyrophoric. Flashpoint - The lowest temperature at which a liquid gives off enough vapor to form an ignitable mixture with air and produce a flame when a source of ignition is present. LEL and UEL - For flammable liquids, the lower explosive limit (LEL) is the minimum concentration of the liquid s vapor in the air, below which, a flame does not occur on contact with an ignition source. The upper explosive limit (UEL) is the maximum concentration of the liquid s vapor in air, above which, a flame does not occur. Suitable extinguishing materials Personal Protective Equipment (PPE) for fire fighters. Fire and Explosion Data for BCL3 Southwest Center for Microsystems Education (SCME) Page 6 of 10

11 Toxicity Nature of Hazard and Toxicity Data - The nature of the hazard (e.g. irritant, corrosive, carcinogen) and significant animal studies that determine the chemical's toxicity commonly based on the LD50 (Lethal Dose, 50%). Toxicity data also includes the dose relative to the length of time exposed, such as the TLV and PEL. TLV and PEL are both legal limits. LD50 - The value that indicates the quantity of material that, if administered to a population of test animals, will cause 50% of the animals to perish. The LD50 is typically expressed in mg of material per kg of subject-body-weight. TLV or Threshold Limit Value - The airborne concentration of a chemical. A TLV is the concentration in ppm (parts per million) under which workers may be repeatedly exposed day after day without adverse effects. TLVs are revised yearly by the American Conference of Governmental Industrial Hygienists. PEL or permissible exposure limit - Similar to TLV, but is set by OSHA. Reactivity Conditions or Materials to Avoid Handling conditions to avoid when using a specific chemical, such as extreme temperatures, shaking, inappropriate storage, or dropping. Also, materials that this chemical should not come in contact with due to chemical reactions. Materials such as water and metals or common "materials to avoid." Hazardous Decomposition Products - Hazardous materials produced from a reaction by burning, oxidation, heating or reaction with other chemicals. Find this information within your SDS's. PPE (Personal Protective Equipment) Reactivity Data for BCL3 Safety equipment (if required) when working around or handling a chemical. Safety equipment could include goggles, face shield, chemical gloves (corrosive or solvent), aprons, shoes, or self-contained breathing apparatus (SCBA). Southwest Center for Microsystems Education (SCME) Page 7 of 10

12 Glossary of Key Terms Flammability - A measure of the extent to which a material will support combustion. Also know as inflammability. SDS (Safety Data Sheet) - A document that provides the necessary information about a chemical for all those that use it, store it, or work around it in any manner. PPE (Personal Protective Equipment) - Equipment employees wear that provides an effective protective barrier between the employee and MSD hazard. Reactivity - A description of the tendency of a substance to undergo chemical reaction with the release of energy. The conditions that cause the reaction, such as heat, or direct contact with other chemicals, are specified as "Conditions to avoid" when a chemical s reactivity is discussed on SDS. Toxicity - The effect a chemical has on the health of a human being under certain concentrations an exposure times. A chemical s toxicity depends on the duration of exposure and the chemical s concentration. Other terms can be found in the SDS HyperGlossary [ Summary A SDS is your information source about a chemical. Before working with or around a chemical, you should always study the appropriate SDS.

20 KOH (Potassium Hydroxide) SDS Activity Participant Guide Description and Estimated Time to Complete This activity allows you to learn more about KOH (Potassium Hydroxide), a chemical used in the fabrication of MEMS. You will study a Safety Data Sheet (SDS) for KOH and write a safety procedure for process technicians that work with KOH. Estimated time to complete: Allow approximately 2 hours NOTE: Safety Data Sheets (SDS) used to be called Material Safety Data Sheets (MSDS). Some websites and documentation you find in this activity may still use the term MSDS. Introduction KOH (Potassium Hydroxide) is one of the most used liquid chemical etchants for creating channels, grooves, and cavities in silicon crystal wafer substrates for microsystems devices. Anyone working within a lab or fabrication environment in which MEMS are made will be working around, if not with KOH. Therefore, it is imperative that one understands the information provided on the SDS and implements all safety precautions and safety rules when working in the cleanroom. For those technicians actually working with KOH, it is imperative that they have a thorough understanding of the potential hazards of the chemical and how to prevent problems from occurring. They also need to know how to respond to any problem that could arise, such as exposure or spill.
