Hazard Communication
Office of Environmental Health and SafetyHunter College of CUNY
CUNY HazCom 2
Overview
• Understanding the Hazard Communication Standard (29 CFR 1910.1200)
• Chemical Properties and Characteristics
• Labels
• Spill Procedures
• MSDS – Material Safety Data Sheets
CUNY HazCom 3
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 4
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 5
Elements of a Written Hazard Communication Program
• Staff Responsibilities
• Labeling Procedures
• MSDS Procedures (obtaining / maintaining)
• Training Program
CUNY HazCom 6
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 7
• 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
Training Requirements
CUNY HazCom 8
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 9
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 11
Flammability
FLAMMABLE = IGNITE EASILY
• Vaporizes quickly at room temperature
• May cause dizziness, nausea, and headaches if inhaled
• Reacts violently with oxidizers
CUNY HazCom 12
Examples of Common Flammable Materials
• Gasoline
• Alcohol
• Paint Thinner
• Aerosol cans
CUNY HazCom 13
Fire Triangle 3 Necessary Ingredients for Fire
FUELsomething that will burn
AIRoxygen
IGNITION SOURCE spark
CUNY HazCom 15
Corrosivity
CORROSIVE = BURNS
• Destroy or damage living tissue irreversibly
• Acids (low pH) or Caustics (high pH)
CUNY HazCom 17
Examples of Common Corrosive Materials
• Bleach (Sodium Hypochlorite)
• Ammonia
• Vinegar (Acetic Acid)
CUNY HazCom 18
Reactives
States
• Solids
• Liquids
• Gases
Types
• Air or water reactive
• Shock, heat or friction sensitive
• Explosive
CUNY HazCom 19
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 20
ToxicityTOXIC = 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 21
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 23
Labels
• Every bottle ordered and received should come with an affixed label containing:
– Name of product and constituents
– Hazards
– Manufacturer’s Name
CUNY HazCom 25
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 AlcoholFlammable
CUNY HazCom 26
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 27
Routes of Exposure
• Breathing (inhalation)
• Skin contact (dermal absorption)
• Swallowing (ingestion)
• Puncture (injection)
CUNY HazCom 28
PPEKnow 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 30
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 31
Large Spill
For a large spill that requires assistance to clean up, call:
• Environmental Health and Safety
• Public Safety
CUNY HazCom 32
Spill KitsA 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 33
Fire Extinguishers4 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 34
Trash, paper, and cloth.
Gasoline, propane, and solvents.
Computers, fax machines, and copiers.
CUNY HazCom 35
Fire Extinguisher UseIf 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 37
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 38
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
