Transcript

  • 1. Laboratory Safety Procedures Presented by: Manar Hassan Safety is our FIRST priority
  • 2. Outlines <ul><li>Health Hazards of Chemicals (Basic Toxicology, Routes of Entry…..). </li></ul><ul><li>Toxic Effects of Chemical Exposure. </li></ul><ul><li>Laser Safety in Lab. </li></ul><ul><li>First Aid. </li></ul><ul><li>Rules to be followed during work in Lab. </li></ul>Safety is our FIRST priority
  • 3. <ul><li>The health effects of hazardous chemicals are often less clear than the physical hazards. </li></ul><ul><li>RISK = TOXICITY x EXPOSURE </li></ul><ul><li>The actual health risk of a chemical is a function of the toxicity and the actual exposure. No matter how toxic the material may be, there is little risk involved unless it enters the body. </li></ul><ul><li>Routes of Entry </li></ul><ul><li>Skin and Eye Contact </li></ul><ul><li>Inhalation </li></ul><ul><li>Ingestion </li></ul><ul><li>Injection </li></ul>Safety is our FIRST priority
  • 4. <ul><li>Toxic Effects of Chemicals </li></ul><ul><li>The toxic effects of a chemical may be  local  or  systemic . </li></ul><ul><li>Local injuries such as strong acids, alkalis or oxidizing agents. </li></ul><ul><li>Systemic injuries such as , methanol that has been ingested may cause blindness, while a significant skin exposure to nitrobenzene may effect the central nervous system. </li></ul><ul><li>Certain chemicals may affect a target organ. For example, lead primarily affects the central nervous system, kidney and red blood cells; isocyanates may induce an allergic reaction (immune system); and chloroform may cause tumors in the liver and kidneys. </li></ul><ul><li>Acute  toxicity results from a single, short exposure. Effects usually appear quickly and are often reversible.  Chronic  toxicity results from repeated exposure over a long period of time. Effects are usually delayed and gradual, and may be irreversible. </li></ul>Safety is our FIRST priority

  • 12. <ul><li>Laser Safety </li></ul>Safety is our FIRST priority
  • 13. Safety is our FIRST priority
  • 14. Safety is our FIRST priority Be Laser Safe! High-power lasers are in use in many research labs and are fundamental to making many of today&apos;s scientific discoveries. Every employee should know the meaning of laser safety signs to prevent inadvertent injury from entering a laser use area.
  • 15. Safety is our FIRST priority Danger! Very high-power lasers may be in use. Even momentary exposures may cause burns or permanent eye damage. Do not enter unless authorized to do so.
  • 16. Safety is our FIRST priority Caution! High power lasers may be in use. Extended exposures may damage the eyes. Do not enter unless authorized to do so.
  • 17. Safety is our FIRST priority Notice! Laser installation, repair, set-up, or modification is in progress. Do not enter.  
  • 18. <ul><li>First Aid in Lab. </li></ul>Safety is our FIRST priority
  • 19. Science Lab Safety Rules Safety is our FIRST priority
  • 20. Safety is our FIRST priority <ul><li>Please don’t be that person. </li></ul>
  • 21. Thanks for your Attention
