5 Interpreting Chemical Labels Description and Estimated Time Primary Knowledge Participant Guide Just like any chemical cleaner you buy at the store, each chemical used in the fabrication of microsystems has a label that contains important information about that chemical. Before using any chemical, READ THE LABEL. This unit provides information on the content and requirements of chemical labels. This information is needed to successfully engage in the activity that is relevant to chemical labels, their content, and interpretation. Estimated time to complete: Allow at least 10 minutes Introduction When working with a chemical, the most accessible information is the information on the chemical bottle's label. The label tells you what the chemical is and any immediate hazards associated with the chemical. Once you know what you are dealing with, you should consult the MSDS (Material Safety Data Sheet) for additional information. OSHA (Occupational Safety and Health Association) requires that all in-plant / in-lab containers of chemicals be labeled, tagged, or marked with the chemical s identity and appropriate hazard warnings. This includes secondary containers as well as primary containers. Learning Module Objectives Be able to interpret the information on at least 3 chemical bottles. Be able to interpret the information on NFPA (National Fire Protection Association) diamonds. State at least three chemical safety rules related to the information found on a chemical label. Southwest Center for Microsystems Education (SCME) Page 1 of 6 Saf_HazMat_PK40_PG_ docx Interpreting Chemical Labels PK

6 Safety Chemicals are dangerous and can cause serious injury or death when handled improperly. One should always read the label and study the Material Safety Data Sheet (MSDS) prior to using, handling, or working with a chemical. Dependencies Knowledge of the terminology associated with hazardous materials and their properties would complement the information presented in this unit. See SCME's Hazardous Materials I and II. Key Terms Chemical labels NFPA (National Fire Protection Association) OSHA (Occupational Safety and Health Association) OSHA Requirement OSHA requires that chemical manufacturers and distributors label every container of hazardous chemicals that they ship. Label requirements are stated in Section (f) of the Hazardous Communication Standard (29 CFR ). These requirements are reviewed in this lesson. Southwest Center for Microsystems Education (SCME) Page 2 of 6 Saf_HazMat_PK40_PG_ docx Interpreting Chemical Labels PK

7 Label Contents 1 When a chemical is shipped from the manufacturer or importer, the chemical's label must contain, at a minimum, the following information: Product Identifier Code and product name Supplier Identification name and address and emergency phone number Hazard Pictograms A Single Word (e.g., Danger, Corrosive, Oxidizer) Hazard and Precautionary Statements The manufacturer's label must remain on the container once received by the customer. For more detailed information about chemical label requirements and to study examples of acceptable labels, read the OSHA Brief Hazard Communication Standard: Labels and Pictograms. Southwest Center for Microsystems Education (SCME) Page 3 of 6 Saf_HazMat_PK40_PG_ docx Interpreting Chemical Labels PK

8 Labels for Secondary Containers If the chemical is transferred to another container, the customer must properly label the new container. All in-plant / in-lab containers of hazardous chemicals must be labeled, tagged, or marked with the following 2 : Chemical s identity Appropriate hazard warnings (physical and health hazards) Modified Label for Secondary Container Hazard Warnings The hazard warning is a brief statement, word, picture, symbol or combination thereof that quickly and clearly states the chemical s immediate hazard(s). Below are commonly used warnings: Flammable Corrosive Causes lung damage Poisonous if swallowed Do not mix with water Standard symbols have been created to represent hazards such as corrosive, flammable, oxidizer and poison. What other hazard warning symbols would you recognize (in addition to the ones shown here)? Southwest Center for Microsystems Education (SCME) Page 4 of 6 Saf_HazMat_PK40_PG_ docx Interpreting Chemical Labels PK

9 The NFPA Diamond (National Fire Protection Association) A quick and easy way to supply the user with critical information about a chemical is the NFPA diamond. The NFPA diamond uses a system of ratings developed by the National Fire Protection Association. These ratings inform the user of a chemical's level of hazard in health, flammability and reactivity. It also warns of any special hazard such as "do not mix with water" or "corrosive". To learn more about the NFPA ratings and how to quickly interpret a NFPA diamond, see SCME's unit on the NFPA Ratings / NFPA Diamond. ANSI Requirements Additional information may be included but is not required by OSHA. However, many manufacturers use a voluntary labeling standard published by the American National Standard Institute (ANSI Z ). This standard calls for the following items in addition to those required by OSHA: Signal words - DANGER, WARNING, CAUTION Highly toxic materials shall be marked POISON Precautionary measures useful in preventing physical harm to the individual Instructions in case of exposure Notes to physician for emergency treatment Instructions in case of fire or chemical spill Instructions for chemical handling and storage Rules for Chemical Labels Read all labels carefully. Double check the label. Know what you are handling. Do NOT use a chemical if it is unfamiliar to you or it has no label. Ensure the chemical container has the proper label. Chemical labels must be legible and prominently displayed. Chemicals poured into a smaller container for daily use must be properly labeled. Never obscure, deface, or remove any label.

10 Summary The chemical label is an immediate warning that a chemical may pose a physical or health hazard to the user. Therefore, it is important that one be able to quickly interpret the information on a chemical label and know when additional information should be acquired. Additional information about a chemical can be found in its Material Safety Data Sheet (MSDS). References 1. OSHA Quick Card for Hazard Communication Standard Labels 2.

11 NFPA Ratings / NFPA Diamond (NFPA National Fire Protection Association) Primary Knowledge Participant Guide Description and Estimated Time to Complete NFPA Ratings / Diamond This unit provides content information about the NFPA (National Fire Protection Association) ratings and related NFPA diamond. By the end of this unit you will be able to interpret NFPA diamonds and relate specific chemicals to NFPA hazard types and levels. This information will prepare you to quickly identify the potential dangers associated with chemicals used in microsystems fabrication. Estimated time to complete: Allow 15 minutes Southwest Center for Microsystems Education (SCME) Page 1 of 7 Saf_HazMat_PK42_PG_ docx NFPA Ratings/NFPA Diamond PK

12 Introduction When working with a chemical, the first information that one usually sees is the information on the chemical s label. The purpose of this information is to warn you of the hazards associated with the chemical. Once warned, you should consult the MSDS (Material Safety Data Sheet) for additional information. OSHA (Occupational Safety and Health Association) requires that all in-plant / in-lab containers of chemicals be labeled, tagged, or marked with the chemical s identity and potential hazards. One instrument commonly used to identify a chemical s potential hazards is the National Fire Protection Association (NFPA) Diamond. NFPA Diamond Dependencies Prior knowledge of the terminology associated with hazardous materials would be beneficial. See SCME Hazardous Materials I and II. NFPA Standard The NFPA ratings were developed by the U.S. National Fire Protection Association. The NFPA diamond is a pictorial representation of these ratings as defined in the NFPA 704 standard. The NFPA diamond is sometimes referred to as the "fire diamond". It is used by emergency personal, employees, students, and the general public to quickly identify the potential hazards of a chemical. Examples of where one might see a NFPA diamond: 18-wheeler transporting a chemical Compressed gas cylinders Doors to storage rooms Entry doors to manufacturing facilities Chemical labels on bottles and crates Southwest Center for Microsystems Education (SCME) Page 2 of 7 Saf_HazMat_PK42_PG_ docx NFPA Ratings/NFPA Diamond PK

13 NFPA Hazard Warnings In a NFPA diamond, each smaller diamond represents a particular hazard. The hazards shown are Flammability (red), Health Hazard (blue), Reactivity (yellow), and Special (white). The number within each diamond represents the "level" of the hazard. NFPA Ratings The level of each hazard represented by a NFPA diamond is given a 0 to 4 rating: 0 = "least severe hazard" 4 = "most severe hazard" Each level represents a specific degree of hazard depending on the category. Some sections, such as Flammability, are well defined and based on a chemical s flashpoint. However, the Health rating can be somewhat subjective. This could be dependent upon the manufacturer s interpretation of the MSDS and the concentration of a chemical. At times you might see different levels for the same chemical. Let s look into each section in more detail. Southwest Center for Microsystems Education (SCME) Page 3 of 7 Saf_HazMat_PK42_PG_ docx NFPA Ratings/NFPA Diamond PK

14 RED: Flammability Ratings The level of hazard is based on the chemical s flashpoint. 4 Extremely flammable. Will vaporize at normal pressure and normal temperature [Flashpoint below 73 F (23 C)] 3 Ignition may occur under most ambient conditions [Flashpoint below 100 F (38 C)] 2 Must be moderately heated for ignition [Flashpoint below 200 F (93 C)] 1 Must be preheated for ignition [Flashpoint above 200 F (93 C)] 0 - Will not burn BLUE: Health Hazard Ratings 4 Deadly: Exposure may cause death or major residual injury 3 Extreme Danger: Exposure could cause serious injury even if treated 2 Hazardous: Intense or prolonged exposure may cause incapacitation or possible residual injury 1 Slightly Hazardous: May cause irritation or minimal residual injury 0 Normal Material: Hazard no greater than ordinary material Southwest Center for Microsystems Education (SCME) Page 4 of 7 Saf_HazMat_PK42_PG_ docx NFPA Ratings/NFPA Diamond PK

15 YELLOW: Reactivity Ratings 4 Can detonate at normal temperatures or pressures 3 Can detonate with shock or strong ignition source, or reacts explosively with water 2 Unstable. Can undergo violent chemical change at elevated temperatures or pressures. Capable of reacting violently or forming explosive mixtures with water. 1 Normally stable, but can become unstable at elevated temperatures and pressures. May react with water, but not violently. 0 Stable. Not reactive with water. WHITE: Special Hazard / PPE Specific symbols are used to indicate hazards such as Reacts with water Strong Oxidizer Corrosive Radioactive Poison White is also used to indicate if specific personal protective equipment (PPE) is required: goggles acid gear respirator Southwest Center for Microsystems Education (SCME) Page 5 of 7 Saf_HazMat_PK42_PG_ docx NFPA Ratings/NFPA Diamond PK

16 Special Hazards These are some of the symbols used in the WHITE of a NFPA diamond. Let's check your understanding of the rating levels. What flammability rating would be given to a chemical that may ignite under most ambient conditions and has a flashpoint less than 100 F? What health rating would a chemical have that may cause irritation or minimal residual injury? What reactivity rating would a chemical have that was capable of reacting violently or forming explosive mixtures with water? What does COR in the White diamond represent? Which of the following would one NOT find in the white section of a NFPA diamond? 1. COR 2. Goggles required 3. OX 4. Reacts with bleach Which of the following is NOT true in reference to the NFPA diamond? a. Prolonged exposure may cause incapacitation b. Flashpoint is less than 200 F c. Can detonate at normal temperature and pressure d. Do not mix with water Southwest Center for Microsystems Education (SCME) Page 6 of 7 Saf_HazMat_PK42_PG_ docx NFPA Ratings/NFPA Diamond PK

17 Summary The NFPA diamond is a reliable warning symbol used on labels, doors, compressed gas cylinders, and other chemical storage devices. Variations of this diamond are found throughout laboratories, manufacturing facilities, and microsystems fabrication facilities. It is important to be able to interpret the information provided in a NFPA diamond. Food for Thought What are ways to remember the colors and their respective warning (health, fire, reactivity or special)? Develop a formula or system for associating the level's flashpoint temperature with its rating. Develop a formula or system for associating the level's health or reactivity rating. References 1.

29 Interpreting Chemical Labels Activity Activity Participant Guide Introduction Microsystems fabrication facilities use a variety of chemicals. Some of these chemicals are very safe to work with. However, some chemicals have characteristics that introduce potential health and physical hazards to the environment and personal. Therefore, it is important to know what you are working with and what potential hazards exist. When working with a chemical, the first information that you might see is contained on the chemical s label. This information is intended to warn you of any immediate hazards associated with the chemical. Once warned, you should consult the Material Safety Data Sheet (MSDS) for additional information. OSHA (Occupational Safety and Health Association) requires that all in-plant / in-lab containers of chemicals be labeled, tagged, or marked with the chemical s identity and any applicable Chemical Bottle with hazard warnings. Many suppliers place the NFPA (National Manufacturer's Label Fire Protection Association) diamond on the chemical label to indicate the physical and health hazards of a chemical. The manufacturer's address must also be on the original chemical bottle. You should know the terminology associated with hazardous materials and the rules when with working with and around chemicals BEFORE completing this activity. Description and Estimated Time to Complete This activity is a Scavenger Hunt. You will locate specific information commonly found on chemical labels. You will demonstrate your ability to locate and extract information from various chemical labels. Using this extracted information, you will develop a NFPA diamond for at least two chemicals. Estimated Time to Complete Allow at least 60 minutes Objectives Locate specific chemical characteristics or warnings on at least 4 different common household or laboratory chemicals List the required items for each chemical label Develop NFPA diamonds for at least two chemicals Southwest Center for Microsystems Education (SCME) Page 1 of 6 Saf_HazMat_AC44-PG_ docx Interpreting Chemical Labels Activity
