Presentation Transcript

  1. Welcome • 3 Components in 1 • Chemical Safety Awareness • The Environmental and Safety aspects of Spills • One builds on the other

  2. Material Safety Data Sheets What You Need To Know

  3. WHY- From The L&I Core Rules • WAC 296-800-14020 - APP • WAC  296-800-160 - PPE • WAC  296-800-180 - MSDSs • WAC  296-800-170 - ECHC • Chemical Hazard Communication

  4. Why – Your Health • Your medical record • MSDS is a record of your exposure to chemicals • Employers must have one for each chemical • Must be kept for 30 years plus the length of employment • You have right to know • As part of understanding how to respond to daily use and spill response

  5. Who Needs This Training? • Any individual that might come in contact with a chemical. • We all do!

  6. Nothing New • People have been writing about chemical exposure for over 2000 years • Pliny the elder, who died in 70 BC, wrote about the dangers of mercury and asbestos • Awareness is part of many classes

  7. Your Health & Safety • The MSDS covers the details • Industrial Hygiene overview covers the big picture and the science • Anticipation • Recognition • Evaluation • Control

  8. Hierarchy of Controls

  9. The Air We Breathe Contaminants • Particulates - solid or liquid • Non-respirable particles - bigger > 10 m in diameter • Respirable particles –smaller, the harmful ones < 10 m in diameter • Gas - not solid or liquid • formless fluids, like air, that expand to occupy a space

  10. Types of Air Contaminants • Particulate – solid or liquid, smaller are worse • Dusts • Fumes - volatilized solids condenses in cool air • hot vapor + air (reaction with) = oxide, < 1.0 m in diameter – Very SMALL! • Mists - suspended solid droplets • Fibers - solid, slender, elongated structures • Gases –like air and carbon monoxide (CO) • Arc-welding, internal combustion engine exhaust • Vapors • liquid changed to gas • organic solvents

  11. Units of Concentration • ppm - parts per million • mg/m3 - milligrams per cubic meter • Mppcf - millions of a particle per cubic foot • f/cc - fibers per cubic centimeter

  12. Acronyms • Regulators for Worker Safety • Federal- OSHA, Occupational Safety and Health Administration • State of Missouri- DLIR-DLS, Department of Labor and Industrial Relations, Division of Labor Standards • NIOSH • National Institute of Occupational Safety and Health • ACGIH • American Conference of Governmental Industrial Hygienists

  13. Exposure LimitsAir Contaminants • Three types of Air Contaminant Limits • TWA - 8-hour Time Weighted Average • STEL – Short Term Exposure Limit (15 min.) • Ceiling – Not to exceed! • OSHA-PEL, ACGIH-TLV, NIOSH-REL, WEEL • Many groups publish limits

  14. Exposure LimitsAir Contaminants • OSHA - Legally enforceable • PEL - Permissible Exposure Limit • Action Level • NIOSH - Center for Disease Control (CDC) • REL - Recommended Exposure Limit • IDLH – Immediately Dangerous To Life or Health • ACGIH American Conference of Government Industrial Hygienists • TLV - Threshold Limit Value

  15. Hazard + Exposure = Potential for Harm

  16. How Chemicals Enter the Body Three Routes of Exposure: Ingestion – swallowing the chemical Inhalation – breathing in the chemical Absorption – the chemical soaks through skin

  17. Hazard + Exposure = Potential for Harm

  18. Best Management Practices • Controls • Regular maintenance • Preventative maintenance • The goal is to reduce the potential for harm

  19. What Products Are Covered? • Chemicals. Ones that create physical and health hazards. Even soaps and lotions if used in the work place as part of our work • What is a chemical? According to L & I • Any element, chemical compound, or mixture of elements and/or compounds. • A chemical can be solid, liquid, or gas

  20. What Makes A Chemical Hazardous? • A chemical, mixture, or physical agent that may cause health effects in short- or long-term exposed employees. • Based on statistically significant evidence from at least one study conducted using established scientific principles. • There is the potential for harm.

  21. Hazards Can Be Physical • Combustible liquid • Compressed gas • Explosive • Flammable • Organic peroxide • Oxidizer • Pyrophoric (spontaneously combustible) • Unstable (reactive) • Water reactive

  22. And To Our Health • Carcinogens ,Toxic or highly toxic agents • Reproductive toxins, Irritants, Corrosives • Sensitizers • Hepatotoxins • Nephrotoxins • Neurotoxins • Substances that act on the hematopoietic system (blood or blood-forming system) • Substances that can damage the lungs, skin, eyes, or mucous membranes • Hot or cold conditions

  23. Health Hazards Translated • Carcinogens • Cause cancer • Toxic or highly toxic agents • Hurt or kill you quickly or with just a little exposure • Reproductive toxins affect • Ability to have children, or • Developing fetus • Sensitizers • Cause allergy-like reactions and as you get sensitized, smaller and smaller amounts of the chemical can cause a response

  24. Hepatotoxins Nephrotoxins Neurotoxins Hematopoietic system toxins Liver Kidney Nervous system brain or other nerves Blood or blood-forming system (bone marrow, etc.) Health Hazards Can Have A “Target Organ” Toxins Organs damaged/ affected

  25. Now in English! • For our purposes, chemicals are the products we use in workplace. They can be: • Liquid - diesel or gasoline • Solids - welding rods • Pastes, creams, etc. • They can make you sick

  26. In English, Again • A hazardous chemical is any chemical that can harm you, if you are exposed to it. • Many industrial chemicals can harm you at some level. • It depends how much gets into your body.

  27. How They Affect Us • Acute • Short time between exposure and onset of signs and symptoms • Chronic • Long time between exposure and the onset of signs and symptoms

  28. You Can Protect Yourself Know what you’re working with and what’s in it, Use the smallest amount of a chemical needed to do the job, Do not use chemicals on tasks where they are not approved, (For example: Brake clean is not an all purpose degreaser!)

  29. You Can Protect Yourself By: Maintaining machinery and equipment to prevent leaks or releases.

  30. Now You Really Want To Read The MSDS

  31. What Is An MSDS • Material safety data sheets (SDS or MSDSs) are the primary way to communicate detailed chemical hazard information to employees. • SDS, or safety data sheet, is another way of saying MSDS.

  32. Not All Forms Are The Same • Some have 8 sections • Some have 16 • There may be pictograms or warning signs or not • They are required to have specific information • The future of MSDS is the GHS, or Globally Harmonized System

  33. Globally Harmonized System The GHS is a system for standardizing and harmonizing the classification and labeling of chemicals. It is a logical and comprehensive approach to information delivery

  34. Again, English • GHS changes MSDS to SDS • Standardizes layout, format and pictograms • The European Union, The US, Canada, Mexico and many other nations are adopting it • It should help multinational companies and us.

  35. Names of hazardous chemicals Physical and chemical properties Physical hazards of working with it Health hazards of working with it (including signs and symptoms of overexposures) Acetone Flammable & highly volatile Burns Headaches, eye irritation What Information Is In The MSDS

  36. The main way the chemical enters the body The legal limit allowed in the air If the chemical is a carcinogen Precautions for safe use of the hazardous chemical Inhalation 750 ppm No Use with adequate ventilation, keep away from open flame What Information Is In The MSDS

  37. Exposure control methods, including personal protective equipment Emergency and first aid procedures The date the MSDS was prepared or revised Name, address and phone number of the person responsible for the information in the MSDS. Wear respirator, Butyl unsupported Eyes: flush with water for 15 minutes 2011 John Doe 1234 Maple St. Anywhere, USA Continued

  38. When do you need an MSDS? At the Kansas City Streetcar, before an employee uses a chemical • An MSDS is • Required • Must be reviewed and approved

  39. Where to find an MSDS? MSDS for approved chemicals can be found online @ https://www.osha.gov/Publications/HazComm_QuickCard_SafetyData.html

  40. Found It, Read It, And Still Don’t Understand It! • We don’t expect you to be a scientist • Talk to your supervisor or Safety Officer • Make sure that you are up to date on all of your training, including: • Any training specific to your job • First Aid

  41. I Looked Up My Product And It Was Not There • We are in the process of finding, counting, and documenting every product used in KCMT • If you have questions about a product, ask your supervisor or Safety Officer • Please do not bring in products with out proper approval

  42. Found It, Read It, Understand It & Ready To Work • Does the product have to be transferred to a secondary container? • Are all the labels in place? • Are all controls in place? • Ventilation, good housekeeping, PPE, • Is the eyewash in working order?

  43. PPE • The MSDS may or may not have specific requirements • Know what you work with and what is required • All PPE is not equal

  44. Is The PPE The Right PPE? • Gloves, eyewear, and respiratory protection are specific to the chemical • Know what gloves you need. • Safety glasses, goggles, or face shield?

  45. PPE - Chemical Resistance Gloves • These gloves may be made of rubber, neoprene, polyvinyl alcohol or vinyl, etc. The gloves protect hands from corrosives, oils, and solvents. When selecting chemical resistance gloves, be sure to consult the manufacturers recommendations, especially if the gloved hand will be immersed in the chemical

  47. PPE – Eye Protection • Some MSDS require that NO contacts be worn when using the product. • Wearers of contact lenses must also wear appropriate eye and face protection. • Face shields should only be worn over primary eye protection (glasses or goggles).

  48. PPE – Eye Protection • Safety glasses, low hazard, general use • Goggles, medium hazard, threat of spill or splashing • Goggles and face shield,high hazard, acids and other toxic chemicals

  49. Eyewash And Shower Required • Corrosives • Acids with a pH of 2.5 or below • Alkaline/bases with a pH of 11 or above. • Irritants – a chemical that creates inflammation or painful reaction • Toxicants - a chemical has the potential of causing injury or illness or death of a living organism

  50. Warning Labels Flammable • Liquids can catch on fire. The difference between flammable and combustible is a matter of degree. • Under 100o F and it is flammable • Over 100o F and it is combustible • They both burn
