Presentation Transcript

  1. Hazards Properties & Toxicology • Definitions • Hazard • Mishap • Risk • Outrage?

  2. Hazards Properties & Toxicology • Hazards: • Chemical • Physical • Biological • Uncontrolled environment • Number & variety of substances • Disorderly physical environment

  3. Hazards Properties & Toxicology • The majority of health hazards arising from work at a TSDF comes from contact w/ chemicals • Toxicology is the science of these health effects, but • Toxicology is based on the physical properties.

  4. Hazards Properties & Toxicology • Physical State • Gases/Vapors • Liquids • mists, fog, aerosols • Solids • dusts, fumes, smoke

  5. Hazards Properties & Toxicology • Chemical Properties • Toxicity • Corrosiveness • Flammability • Flash point, LEL/UEL • Vapor Pressure/Vapor Density • Stability/Reactivity

  6. Hazards Properties & Toxicology • Toxicology • Dose Response Curves • Acute vs Chronic • Routes of Entry • Detoxification • Toxic Effects

  7. Hazards Properties & Toxicology • Toxicology Measures • LC50, LD50 • TLV, PEL, OEL, REL, MAC • TWA, STEL, Ceiling • IDLH

  8. Hazards Properties & Toxicology • Monitoring • Personal • General Area • Process • Continuous • Periodic • Direct Reading vs Grab vs Shift

  9. Hazards Properties & Toxicology • Monitoring Weather Factors • Wind Speed/Stack Speed • Temperature/Pressure changes • Instrumentation • FIDs, PIDs • Sampling Pumps (filters/sorbents) • Colorimetric Tubes

  10. Hazards Properties & Toxicology • PPE Selection Should be based on the actual hazard present • Fit Factors • Permeation Data • May be based on the concntration present if no data is known • 0-5ppm, 5-500ppm, 500-1000ppm

  11. HazardsDiscussion • What are the 3 states of matter? • Name an physical illness hazard? • What is a fume? • What is the flash point? • What is a vapor • What are the 4 routes of entry? • What is a PEL? LC50?, TWA?
