Hazard communication Chemical Safety on the Job
We use many chemicals • We want you to know how to use them safely. • You will learn about: • The Hazards of chemicals. • Our written program. • How chemicals are labeled. • Safe use of chemicals. • Material Safety Data Sheets • Basic procedures for spills. • Who you can ask for more information.
Hazards of Chemicals • There are 2 basic types of chemical hazards: • Physical Hazards • Health Hazards • The first rule of Chemical safety is… "Know what you are working with and how to protect yourself and others.“
Physical Hazards • Chemicals are classified as having Physical Hazards if they are: • Explosive • Compressed Gas • Combustible Liquids • Flammable • Unstable • Water Reactive • Oxidizers
Physical Hazards • Some chemicals may be safe by themselves, but become dangerous when in contact with other substances.
Chemicals with Physical Hazards • Used only by trained employees. • Stored in a safe manner. • Never mixed with other chemicals unless by an approved procedure.
Health Hazards • Chemicals are classified as being a health hazard if they: • Can cause cancer. • Are poisonous (toxic). • Cause harm to your skin, internal organs, or nervous system. • Are corrosive - such as acids. • Cause allergic reactions after repeated exposure.
Ways Chemicals can enter the body • Your lungs if you breath fumes, mists or dust. • Your skin if liquid or dust touches or spills on you or splashes in your eyes. • Your mouth if you eat after handling chemicals. • Accidental swallowing of a chemical.
Health Effects • Some chemicals affect specific organs such as your kidneys, liver, reproductive or nervous system.
Our Written Hazard Communication Program provides • Written information on hazards. • Lists Chemicals we use and their hazards. • System for ensuring chemicals are labeled. • Means to ensure we have an Material Safety Data Sheet (MSDS) for each chemical.
Our Written Hazard Communication Program • Lists who is responsible for the program. • Provides chemical specific safety training methods. • Tells you where to find chemical safety information. • You can see a copy of our written program by asking you supervisor.
Labeling of Chemicals • Chemical Labels provide information on Identity, Hazards and Safe Use. • All chemical containers are labeled by the manufacturer. • Our company may place additional labels on the containers.
Labeling of Chemicals • If chemicals are placed in another container, this new container must have a label placed on it. • All containers must be properly labeled.
Uniform Labeling System • Our Company “Uniform Labels” are used to ensure we have one labeling system. • These may be placed on containers when chemicals are delivered to us or chemicals are transferred to other containers.
2 Basic “Uniform Labels” • HMIS - Hazardous Material Identification System • NFPA - National Fire protection Association Both types must identify the chemical name and hazards
Uniform Labels • Pictures may be used to identify hazards and required protection. • This Information may also be on the Manufacturer’s label.
HMIS & NFPA labels are very similar • Both use colored boxes to identify specific hazards. • Numbers or codes in the boxes tell you the hazard value - higher number = higher hazard.
NFPA & HMIS Label Colors • Red - Fire Hazard • Blue - Health Hazard • Yellow - Reactivity Hazard - explosive, unstable • White - Special Hazards - corrosive, radioactive, water reactive, acid
NFPA Label • The purpose of the NFPA 704 labeling system is to provide a way of quickly identifying the various fire related hazardous associated with a particular material. The NFPA 704 "diamond" is commonly found on bulk storage containers, but is also widely used on chemical containers and MSDS sheets.
NFPA Flammability Codes • 4 Materials that will rapidly or completely vaporize at atmospheric pressure and normal ambient temperature, or that are readily dispersed in air and that will burn readily. Liquids with a flashpoint below 73ºF and a boiling point below 100ºF.
NFPA Flammability Codes • 3 Liquids and solid that can be ignited under almost all ambient temperature conditions. Liquids with a flashpoint below 73ºF and a boiling point above 100ºF or liquids with a flashpoint above 73ºF but not exceeding 100ºF and a boiling point below 100ºF.
NFPA Flammability Codes • 2 Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur. Liquids with flashpoint above 100ºF but not exceeding 200ºF.
NFPA Flammability Codes • 1 Materials that must be preheated before ignition can occur. Liquids that have a flashpoint above 200ºF. • 0 Materials that will not burn.
NFPA Health Hazard Codes • 4 Materials that on very short exposure could cause death or major residual injury. • 3 Materials that on short exposure could cause serious temporary or residual injury.
NFPA Health Hazard Codes • 2 Materials that on intense or continued, but not chronic exposure could cause incapacitation or possible residual injury.
NFPA Health Hazard Codes • 1 Materials that on exposure would cause irritation but only minor residual injury. • 0 Materials that on exposure under fire conditions would offer no hazard beyond that of ordinary combustible material.
NFPA Reactivity Hazard Codes • 4 Materials that in themselves are readily capable of detonation or of explosive decomposition or reaction at normal temperatures and pressures.
NFPA Reactivity Hazard Codes • 3 Materials that in themselves are capable of detonation or explosive decomposition or reaction but require a strong initiating source or which must be heated under confinement before initiation or which react explosively with water.
NFPA Reactivity Hazard Codes • 2 Materials that readily undergo violent chemical change at elevated temperatures and pressures or which react violently with water or which may form explosive mixtures with water.
NFPA Reactivity Codes • 1 Materials that in themselves are normally stable, but which can become unstable at elevated temperatures and pressures.
NFPA Reactivity Codes • 0 Materials that in themselves are normally stable, even under fire exposure conditions, and which are not reactive with water.
NFPA Special Hazard Codes • ACID = Acid Products • ALK = Alkali or Bases • COR = Corrosive Products • OX = Oxidizer • W =Reacts with water • Radioactive
What do I do • Ff there is no label or I cannot read the label? • STOP - do not use the chemical. • TELL your supervisor. • READ the MSDS and have another label put on the container.
Chemicals can be safely used if • You know the hazards and how to protect yourself. • They are used only for approved purposes. • They are stored properlyyou use the correct personal protective equipment. • You do not eat in areas where chemicals are used. • You wash immediately if you come in contact with chemicals.
Chemical Disposal • Each chemical and container must be disposed of properly. • No container is truly "empty" unless properly cleaned. • Follow MSDS requirements for container disposal. • Recycle unused chemicals. • Do not place hazardous chemicals in normal trash receptacles. • Do not pour chemicals into sinks, onto the ground or in storm drains.
Safe Storage • Store incompatible chemicals in separate areas. • Limit the amount of flammable material to the minimum needed. • Store flammable liquids in approved flammable storage lockers. • Store acids in separate flammable storage lockers. • Do not store chemicals in a refrigerator used for food storage. • Do not store food in refrigerators used for chemical storage.
In case of an emergency • Implement the proper Emergency Action Plan. • Evacuate people from the area. • Isolate the area- keep other from entering. • Turn off ignition and heat sources. • Only trained employees are permitted to clean up spills.
Material Safety Data Sheets (MSDS) • Show chemical safety information. • Each chemical has a separate MSDS. • MSDS is written by the chemical manufacturer. • MSDS are kept in the workplace for your use. • If you can't find an MSDS, ask your supervisor. • Are provided by the chemical manufacturer to provide additional information concerning safe use of the product.
Each MSDS tells you • Common Name and Chemical Name of the material. • Name, address and phone number of the manufacturer. • Emergency phone numbers for immediate hazard information. • Date the MSDS was written. • Hazardous ingredients. • Physical & Health Hazards of the chemicals. • Identification of chemical and physical properties. • First Aid / Emergency Information. • Safe handling and use information.
MSDS • Have specific hazard information on: • Fire & Explosion • Chemical Reactions • Control Measures • Health Hazards • Spill & Leak Procedures
MSDS Fire & Explosion Information • Material Flash Point, auto-ignition temperature and upper/lower flammability limits. • Fire extinguishing agents to be used. • Fire fighting techniques. • Any unusual fire or explosive hazards.
MSDS Reaction Information • Stability of chemical. • Conditions and other materials which can cause reactions with the chemical. • Dangerous substances that can be produced when the chemical reacts.
MSDS Control Measures • Engineering Controls required for safe product use. • Personal protective equipment required for use of product. • Safe storage requirements and guidelines. • Safe handling procedures.
MSDS Health Hazards • Permissible Exposure and Threshold Limits (PEL & TLV). • Symptoms of exposure. • Routes of entry into the body. • Medical conditions that can be made worse by exposure. • Cancer causing properties. • Emergency & First Aid Procedures.
MSDS Spill & Leak Procedures • Clean up techniques. • Personal Protective Equipment to be used during cleanup. • Disposal of waste & cleanup material.
Protecting Yourself • Personal Protective Equipment (PPE) may be needed to protect yourself from chemical hazards. • Use the PPE our Company has required for each chemical. • Check the PPE before use to make sure it is not damaged. • Use face shield and Goggles if there is a splash hazard. • Use the proper respirator for dusts, mists and fumes. • Use the right gloves when handling chemicals. • Properly clean and store your PPE after use. • Don't take PPE home - why risk exposing your family?
Stay safe when using chemicals • Know what you are working with. • Know where MSDS are located and how to use them. • Ask your supervisor if you have questions. • Only trained employees may use chemicals.
Stay Safe • Make sure all containers are properly labeled. • Use the proper protective equipment. • Store chemicals only in approved areas. • Immediately report leaks and spills. • Dispose of used chemicals and containers properly.
