Hazard Communication Office of Environmental Health and Safety Hunter College of CUNY
Overview • Understanding the Hazard Communication Standard (29 CFR 1910.1200) • Chemical Properties and Characteristics • Labels • Spill Procedures • MSDS – Material Safety Data Sheets CUNY HazCom
Purpose • The Hazard Communication Standard was created to ensure that the hazards of all chemicals produced or imported are evaluated, and that this information is transmitted to all employees CUNY HazCom
Hazard Communication = Right to Know Employees have the right to know what kinds of hazardous chemicals they work with or are exposed to in their work environment and what possible health effects these chemicals might pose CUNY HazCom
Elements of a Written Hazard Communication Program • Staff Responsibilities • Labeling Procedures • MSDS Procedures (obtaining / maintaining) • Training Program CUNY HazCom
Information Requirements • Employees must be informed of: • Requirements of the Hazard Communication Standard • Operations in work areas where there are hazardous chemicals • Location/availability of written Hazard Communication Program CUNY HazCom
Training Requirements • Employees must be trained in • Methods to detect the presence or release of hazardous chemicals • Physical and health hazards of chemicals in work area • Personal protection CUNY HazCom
Where will you find chemicals at CUNY? • Cleaning supplies • Bleach, ammonia, detergents • Paint Shop • Paints, paint thinners, paint strippers • Laboratories • Assorted chemicals and chemical waste • Mechanical Rooms / Boiler Rooms • Oils, grease, cleaners CUNY HazCom
What is a Hazardous Chemical? 2 Types of hazards: • Physical hazard • Flammables • Corrosives • Reactives • Health hazard Causing acute or chronic health effects (Neurotoxin, carcinogen, mutagen, teratogen, irritant, etc.) CUNY HazCom
Flammables • Aerosols • Gases • Liquids • Solids CUNY HazCom
Flammability FLAMMABLE = IGNITE EASILY • Vaporizes quickly at room temperature • May cause dizziness, nausea, and headaches if inhaled • Reacts violently with oxidizers CUNY HazCom
Examples of Common Flammable Materials • Gasoline • Alcohol • Paint Thinner • Aerosol cans CUNY HazCom
Fire Triangle 3 Necessary Ingredients for Fire FUEL something that will burn AIR oxygen IGNITION SOURCE spark CUNY HazCom
Corrosives • Solid • Liquid • Gas CUNY HazCom
Corrosivity CORROSIVE = BURNS • Destroy or damage living tissue irreversibly • Acids (low pH) or Caustics (high pH) CUNY HazCom
The pH Scale CUNY HazCom 16 CUNY HazCom
Examples of Common Corrosive Materials • Bleach (Sodium Hypochlorite) • Ammonia • Vinegar (Acetic Acid) CUNY HazCom
Reactives States • Solids • Liquids • Gases Types • Air or water reactive • Shock, heat or friction sensitive • Explosive CUNY HazCom
Examples of Common Reactive Materials • Metallic sodium • Metallic calcium • Dry picric acid Reactives should only be found in laboratories and should be carefully stored and monitored. CUNY HazCom
Toxicity TOXIC = POISONOUS High Toxicity – small dose causes severe effect Chronic Toxicity – effect from repeated exposure over long periods of time Acute Toxicity – immediate and severe effect CUNY HazCom
Classes of Toxicity Carcinogens - cancer causing or potentially cancer causing Irritants - non-severe, short term effect that is reversible Sensitizers - may cause allergic reaction after repeated exposure CUNY HazCom
NFPA Hazard Diamond CUNY HazCom CUNY HazCom
Labels • Every bottle ordered and received should come with an affixed label containing: • Name of product and constituents • Hazards • Manufacturer’s Name CUNY HazCom
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 CUNY HazCom
Old Chemical Bottles Do not keep old bottles of chemicals that you will not use If a label is deteriorating or falling off, make a new one or the chemical will be considered as an UNKNOWN CUNY HazCom
Routes of Exposure • Breathing (inhalation) • Skin contact (dermal absorption) • Swallowing (ingestion) • Puncture (injection) CUNY HazCom
PPE Know what Personal Protective Equipment (PPE) is available and where to get it • Gloves • Eye protection (safety glasses, goggles) • Respiratory Protection • Apron / coveralls Some people may be sensitive or allergic to latex gloves CUNY HazCom
What should you do if you spill a chemical or find a spilled chemical? CUNY HazCom
Small Spill Clean up a spill only if you: • Are familiar with the substance that was spilled • Know the substance’s toxicity • Have adequate personal protective equipment • Feel completely comfortable cleaning it up CUNY HazCom
Large Spill For a large spill that requires assistance to clean up, call: • Environmental Health and Safety • Public Safety CUNY HazCom
Spill Kits A spill kit should be available in all areas where chemicals are stored or used The spill kit should contain (at a minimum): • Gloves & Goggles • Absorbent / Neutralizer • Scoop / mini shovel • Bag / container Restock the spill kit as soon as possible whenever anything is used or removed from it CUNY HazCom
Fire Extinguishers 4 Classes • Class A - paper, lumber, cardboard, plastics. • Class B - gasoline, kerosene, organic solvents. • Class C - energized electrical equipment including appliances, switches, panel boxes, power tools, hot plates and stirrers. • Class D – combustible/pyrophoric/organometallic metals, such as magnesium, sodium, and potassium. These materials burn at high temperatures and will react violently with water, air, and/or other chemicals. Handle with care!! CUNY HazCom
Gasoline, propane, and solvents. Computers, fax machines, and copiers. Trash, paper, and cloth. CUNY HazCom
Fire Extinguisher Use If you use a fire extinguisher to put out a small fire, remember: Pull the pin Aim at base of fire Squeeze the trigger Sweep from side to side CUNY HazCom
Safety Showers • Know the location of the nearest safety shower in case of emergency • Make sure it’s accessible, in good working order, and that its inspection is up-to-date CUNY HazCom
Eye Wash • Know the location of the nearest eye wash in case a chemical comes in contact with your eye • Flush your eye(s) for at least 15 minutes • Eye wash stations should be flushed weekly CUNY HazCom
Material Safety Data Sheets(MSDS) CUNY HazCom
Where can you find an MSDS for a chemical? • An MSDS MUST be available anywhere a chemical is used or stored • Each person must know how and where to find an MSDS in the immediate area • An MSDS should be included with the purchase of a chemical. Many are available online. • Ask EH&S if you have having difficulty locating an MSDS or getting one from a manufacturer CUNY HazCom
