Hazard Communication = Right-To- Know Training OSHA’s Hazard Communication or Right-To-Know
Hazard Communication • Hazard communication (3 W’s and One H) Do you know: 1.Where to find information concerning the hazards of the chemicals present in your work area? 2. When to use a laboratory chemical hood? 3. How to select appropriate eye protection? What about gloves? 4. What to do in case you are involved in a fire or chemical emergency? • These are information that you need to know to help you do your work in the safest manner possible. • It is also information that you have a right to know under OSHA standards enacted to protect your health and safety through better communication, better training, and better work practices.
OSHA’s Hazard Communication Program • The Hazard Communication Standard was created to: • Ensure that the hazards of all chemicals produced or imported are evaluated, • Transmit all information to all employees.
Information Requirements • Employees must be informed of: • Requirements of the Hazard Communication Standard. Employer: Notification, Information, Record-keeping • Health effects (Acute Vs. Chronic) • Operations in work areas where there are hazardous chemicals. Labs, shops, storage and preparation rooms. • Location/availability of written Hazard Communication Program. EHS Office at HE-1211A
Training Requirements • Employees must be trained on the following: • Methods to detect the presence. (Labels, MSDS) • Physical and health hazards of chemicals in work area. (Health, Flammability, Reactivity, etc.) • Personal protection

User Labeling • EVERY bottle must be labeled to identify its contents (even soap and water, if there is no original label) • You may use a piece of tape, a sharpie, or print out a label • As long as it is clearly legible and includes the commonly recognized name of the contents (not the chemical formula) and its hazard(s) Rubbing Alcohol Flammable
Chemical Storage • Chemical storageSafe storage of chemicals is a necessity in every laboratory. It will: - Provide for effective management of chemicals. - Lessen the risk of fire. - Prevent accidental mixing of incompatible chemicals in emergencies. - Minimize exposure to corrosive and toxic chemicals.Safe chemical storage may seem to be a matter of common sense. Yet in fact, it requires an awareness of each chemical's potential hazards, and a lot of thought.
Rules of thumb for safe storage • Rules of thumb for safe storage 1. Store chemicals that can ignite at room temperature in a flammables cabinet. If flammable chemicals require cold storage, store only in refrigerators approved for such use. 2. Storage areas for corrosive, toxic, flammable, and highly reactive chemicals should be near a laboratory chemical hood to encourage use of the hood when transferring chemicals. 3. Store only cleaning materials directly under the sink. 4. Never store liquid hazardous chemicals above eye level. 5. Store heavy chemical containers on lower shelves, not on the floor. 6. Store chemicals on shelves with raised edges.
WARNING-PEROXIDE FORMER This material will form explosive peroxides during storage and must not be kept for more than _____months after opening.(see Peroxide Policy at http://www.hunter.cuny.edu/ehs) Date Received_____________Date Opened _____________Discard unopened container 12 months after receipt. Call EH&S at ext. 4462 for disposal. DO NOT USE IF OPENED MORE THAN ________MONTHS. Safe Storage Handling and Disposal of Peroxide-Forming Chemicals - Do not store more chemicals than you will need over a reasonable period. - Peroxide-forming chemicals should be labeled showing (Date of Receipt, Date of Opening). Use this label: - Never store highly reactive chemicals for longer than 6 months. - Never store a chemical with an obscured or missing label. - Separate chemicals into compatible groups and store alphabetically within the groups. - Designate separate storage areas for highly toxic chemicals.
Dry Chemical Storage • Dry chemical storage Dry chemicals can be stored together. To ensure compatibility, keep organic and inorganic chemicals segregated. • Liquid chemical storage The first step is to determine the major storage groups such as acids, bases, flammables, oxidizers, and highly toxic chemicals. • Acids. Acids should be stored in trays that will catch any spill and provide adequate segregation. • Organic acids, organic bases, and flammables. Organic acids and organic bases may be stored with the flammables, but acid resistant plastic trays must carefully segregate them. • Oxidizers. Oxidizers are highly reactive. They should be separated from other chemicals.
Highly toxic chemicals • Highly toxic chemicals - Toxic materials like carcinogens and reproductive hazards should be stored in a separate cabinet.- Volatile toxic materials should be stored in an enclosure.- An inventory should be kept of all highly toxic and highly reactive chemicals.
PPE (Personal Protective Equipment) Always protect your eyesSafety glasses with side eye shields, splash goggles, and full face shields offer varying degrees of protection against splattering chemicals and airborne objects. Choose safety glasses with side eye shields when there is a splash hazard with a small quantity of a hazardous chemical.
PPE (Goggles, Face shields) • GogglesWear goggles when you are handling a chemical that is highly caustic or in a larger volume, perhaps a liter or more.Face shieldsWear a face shield when you are handling a very large volume of a hazardous chemical, or when you need to protect your face and your eyes.
PPE (Gloves) • GlovesWearing gloves is a simple and effective way to protect yourself from chemical contact, but the gloves must be resistant to the specific chemical with which you are working.No glove material is impermeable to all chemicals, therefore, the most effective practice in using protective gloves is to change them frequently and whenever they are contaminated.
Emergency Procedures • Emergency Procedures Eye Splash 15 mins eye shower, keep lids open, consult a physician/opthalmologist. Chemical spill on clothes remove contaminated clothes, activate emergency shower, remove shoes, consult a physician.
Lab Safety Standard Training Lab Safety Standard or Occupational exposure to hazardous chemicals in laboratories(29 CFR 1910.1450)
OSHA Lab Standard, 29 CFR 1910.1450. • A standard (may 1, 1990) for occupational exposure to hazardous chemicals in industrial, clinical and academic laboratories • Provide work practices, procedures and policies to ensure the protection of employees from potentially hazardous chemicals in use in their work area. • Requires a Chemical Hygiene Plan
Chemical Hygiene Plan • Chemical Hygiene PlanHunter College has a written Chemical Hygiene Plan. The Plan conveys the hazards of chemicals which may be present in your work area, and describes appropriate work practices, procedures and controls which are in place to protect you from those hazards.You should become familiar with the Chemical Hygiene Plan or other laboratory safety documents. You may request copies of these materials from: 1) supervisor or 2) Environmental Health and Safety office.
What is a Hazardous Chemical? Two Types of Hazards • Physical Hazard • Flammables/Combustibles • Corrosives • Reactives • Health Hazard • Causing acute or chronic health effects • (Neurotoxin, carcinogen, mutagen, teratogen, infectious agents.)
Physical Hazards • Research employee injuries, 1993 - 1997*The most common serious injuries: cuts due to careless use of razor blades.
Physical Hazards • Laboratory support injuries, 1993 - 1997*The most common serious injuries: strains and fractures due to falls and improper lifting of heavy objects
Physical Hazards • Administrative support injuries, 1993 - 1997*The most common serious injuries: strains and fractures due to falls and improper lifting of heavy objects.
Physical Hazards HazardsRespect the dangers of high voltage, ultraviolet light, heat sources, and cryogenic materials • When transporting hazardous substances, make certain that the containers are sealed and use secondary containers. Try not to take routine manipulations for granted, especially those involving glass, needles, or sharps. • And, if you are fatigued or distracted, take a break, relax and refocus. If you notice any unsafe conditions or have an accident or injury, talk with your supervisor.
