HAZARD COMMUNICATION Bradley Jones Hazard Communication 29 CFR 1910.1200
HAZARD COMMUNICATION • OSHA created the Hazard Communication Standard to help ensure your safety when working with hazardous chemicals. • You have a RIGHT TO KNOW about the hazardous chemicals you use on the job and how to work safely with those chemicals.
HAZARD COMMUNICATION • What are hazardous chemicals, • What are material safety data sheets, • What is on product labels, • How hazardous chemicals affect the body, • What are the different types of hazardous chemicals, • How to protect yourself from hazardous chemicals.
Do I need a Hazcom Program? • Do you: • Sell • Store • Transport • Use chemicals in your process
HAZARDOUS CHEMICALS • “Hazardous chemical" means any chemical which is a physical hazard or a health hazard. • Most chemicals used in the industrial world can harm you in some way.
LABELING • The manufacturer, • The name of the product, • A hazard warning, • A list of hazardous ingredients
MSDS Sheets • Names of hazardous chemicals in a product, • Physical and chemical properties of the product, • Physical hazards of working with the product, • Health hazards of working with the product (including signs and symptoms of overexposures) ACETONE FLAMMABLE AND HIGHLY VOLATILE BURNS HEADACHES, EYE IRRITATION
MSDS Inhalation • The main way the chemical enters the body • The legal limit allowed in the air • If the chemical is a carcinogen • Precautions for safe use of the hazardous chemical 750 ppm No Use with adequate ventilation, keep away from open flame
MSDS Wear respirator, rubber gloves • Exposure control methods, including personal protective equipment, • Emergency and first aid procedures, • The date the MSDS was prepared or revised, • Name, address and phone number of the person responsible for the information in the MSDS. Eyes: flush with water for 15 minutes 1996 John Doe 1234 Maple St. Anywhere, USA
TYPES OF EXPOSURE • Ingestion – swallowing the chemical • Inhalation – breathing in the chemical • Absorption – the chemical soaks through the skin
Types of Hazardous Chemicals • Solids: • Powder • Dust • Fumes • Fibers • Liquids: • Mist • Concentrates • Mixtures • Gas: • Vapors
EXPOSURES LIMITS • Many chemicals have exposure limits, or allowable amounts of a chemical in the air. • These limits are often called “Permissible Exposure Limits” • They are based on 8-hour average exposure or ceiling or peak levels. • Levels must be kept below these limits for safety.
CARCINOGENS • Carcinogens are cancer-causing compounds. • Some chemicals are known human carcinogens, others are only suspected as carcinogens. DOSH (California Division of OSH) has regulations covering the general use of carcinogens, and has specific regulations for several known human carcinogens.
CORROSIVES • Sulfuric Acid • Ammonia • Chromic acid • Lye • Acetic Acid • Chlorine
FLAMMABLE LIQUIDS • The vapor of a flammable liquid ignites and causes fire or explosion – not the liquid itself. • The flammability of a liquid depends on its physical properties: • Vapor Pressure • Flash Point • Limits of Flammability • Vapor Density
LABELING NFPA = National Fire Protection Association Blue = Health Red = Flammability Yellow = Reactivity White = Other hazards or special handling Scale: 0 (No Hazard) to 4 (Extreme Hazard)
HMIS Labeling • The HMIS labeling system operates on the same principle as the NFPA diamond. • It also uses a numerical system from 0-4 to indicate the severity of the hazard. • These labels should be used on individual containers of hazardous materials • Barrels, bottles, cans, buckets, tubs, etc
CARCINOGENS • Signs available from multiple vendors • Compliancesign.com • Labelmaster.com • Uline.com
PROTECTION FROM HAZARDS • Engineering / job specific controls • Knowing what is in the product your work with • Using the smallest amount of a chemical to do the job • Maintaining machinery and equipment to prevent leaks or releases
PROTECTION FROM HAZARDS • Using available ventilation to reduce amounts of chemicals in the air Keeping lids, doors or covers closed on chemical processes
Personal Protective Equipment • Dust masks and respirators • Glasses, goggles, and face shields • Hearing protection • Gloves • Foot protection • Head protection • Aprons or full-body suits
Administrative Controls • Change the chemicals being used for less toxic substitutes • Rotating workers in shifts in hazardous areas • Separating work / eating areas to reduce exposure • Implementation of hand washing procedures
Training • 1910.1200 (h) • Employers shall provide employees with effective information and training on hazardous chemicals in their work area at the time of their initial assignment, and whenever a new physical or health hazard the employees have not previously been trained about is introduced into their work area.
Recordkeeping • 1910.1020(d)(1)(i)(C)The medical records of employees who have worked for less than (1) year for the employer need not be retained beyond the term of employment if they are provided to the employee upon the termination of employment. • 1910.1020(d)(1)(ii)"Employee exposure records." Each employee exposure record shall be preserved and maintained for at least thirty (30) years, except that:
Recordkeeping • 1910.1020(d)(1)(ii)(B)Material safety data sheets and paragraph (c)(5)(iv) records concerning the identity of a substance or agent need not be retained for any specified period as long as some record of the identity (chemical name if known) of the substance or agent, where it was used, and when it was used is retained for at least thirty (30) years
