Session Objectives • You will be able to: • Understand the hazards of materials in your work area • Interpret information on warning labels • Understand material safety data sheets (MSDSs) • Protect yourself • Respond to emergencies
Encounters with Hazardous Materials • We encounter potentially hazardous materials almost every day: • Filling your vehicle with gasoline • Cleaning the house • Applying pesticides or insecticides • Using solvents or acids at work Many materials can cause injury or illness!
Encounters with Hazardous Materials (cont.) • 30 million workersexposed or potentiallyexposed to 650,000materials annually • 20,000 incidents ofexposure annually result in lost workdays
Hazard Communication Law • As an employer, we must provide you with: • A written hazard communication program • A list of hazardous materials • MSDSs • Training
Hazard Communication Law(cont.) • You must be able to: Read labels and MSDSs Follow employer instructions and warnings Identify hazards before starting a job Participate in training

Health Hazards • Short-term effects • Headache, dizziness, skin irritation • Long-term effects • Liver or lung damage or cancer • Materials with health hazards include those labeled as: • Corrosive • Toxic
Hazardous Materials At This Facility • Types of hazardous materials • Locations of hazardous materials
How Hazardous Materials Enter Your Body • Skin absorption and eye contact • Inhalation
How Hazardous Materials Enter Your Body (cont.) • Ingestion (eatingcontaminated food) • Penetration through a cut, puncture, or injection
How Hazardous Materials Affect Your Body Match the term with its explanation below. Chronic Effects Acute Effects Dosage Amount of hazardous material you are exposed to Short-term effects that usually disappear when you are no longer exposed Long-term effects that develop over a period of exposure
PEL TLV TWA STEL Exposure Limits • Permissible exposure limit (PEL) • Threshold limit value (TLV) • Time-weighted average (TWA) • Short-term exposure limit (STEL)
What’s Wrong Here? • Worker assigned to clean screens • Given a cleaner, brush, and rag • Identify the hazard(s)

Review animation Read the Label • Identity of the material • Manufacturer contact information • Physical/health hazards • Special handling • PPE recommendations • First aid, fire response,and spill cleanup
What’s on the Label? The product label shows: • The name of the material • The manufacturer • Miscellaneous safety information • Hazard warnings • List of hazardousingredients • The product label shows: • The name of the material • The manufacturer • Miscellaneous safety information • Hazard warnings • List of hazardousingredients Image Credit: University of Utah, Physics Department
NFPA Labeling Systems • Blue = Health hazard • Red = Flammability • Yellow = Instability • White = Other hazards • Numbers: 0 (No Hazard) to 4 (Extreme Hazard)
In-Plant Labeling • Use for: • Secondary containers • Stationary process containers or vessels • Portable or temporary containers • Include tags and process batch sheets
Information Resource: The MSDS • Is a written description of a hazard related to a material • Describes the risks, precautions, and remedies to exposure • Must be readily available to you • Read the MSDS before working with any material!
The MSDS(cont.) • Identity of material and manufacturer • Ingredients • Hazards • First-aid and fire-fighting measures
The MSDS(cont.) • Accidental release • Handling and storage • Exposure controls and PPE • Physical and chemical properties • Stability, reactivity, toxicity • Ecological and disposal info • Transportation, regulatory, and other info
Labels and MSDSs • Do you understand about properties of materials, labeling, and the contents of MSDS?
Image Credit: Web Soft Safety Solutions PPE: Physical Protection • Face shields/goggles • Gloves • Foot protection • Head protection • Aprons or full bodysuits
PPE: Respiratory Protection • During installation of engineering controls • During maintenance • Nonroutine tasks • Emergency response • When other controls are inadequate • When other controls are not feasible
Emergency Response to Spills • Eyes: Flush with water for 15 minutes • Skin: Wash with soap and water, remove contaminated clothing • Inhalation: Move to fresh air • Swallowing: Get emergency medical assistance
Emergency Response to Spills or Leaks • Evacuate the area • Notify a supervisor or the emergency response team • Stay away
What Should Be Done? • Receive right-to-know training • Access MSDS • Read labels • Wear PPE
Key Points to Remember • Identify hazards. • Read labels and MSDSs. • Follow warnings and instructions, or ask your supervisor if in doubt. • Use the correct PPE. • Practice sensible, safe work habits. • Learn emergency procedures.
