  1. TheGlobally Harmonized System of Classification and Labeling of Chemicals (GHS), Safety Data Sheets, Labels, OSHA, and You Janet L. Keyes, CIH 11 April 2013

  2. What’s GHS? Why? Lots of chemicals out there Lots of international trade Can’t we just agree? 1992, Rio, UN Conference on Environment & Development 2002: first version approved 2012: OSHA adopted

  3. What GHS tries to do Classify chemicals according to hazard Standardize the language, warnings Make it easier for: Suppliers/manufacturers Users And not conflict with transport

  4. GHS in the US OSHA: adopted Revision to HazComm standard and others EPA: pondering Pesticides DOT: adopted in hazmat (49CFR) regs CPSC: began considering Federal Hazardous Substances Act

  5. What does OSHA’s adoption of GHS mean? 2013, December 1:Employees trained on labels, SDS 2015, June 1: MSDSs replaced by SDSs Your SDSs updated 2015, December 1:No old labels shipped 2016, June 1: in-house labels updated

  6. Other standards change All substance-specific hazards (e.g., lead), Welding standard Change warning sign language Laboratory, PSM, Hazwoper Flammable Liquids (use, spray, dip) Change definitions Combustibles (IIIB) goes away

  7. What’s changed in HazComm? • Classification of hazards • Based on specific criteria • Physical hazards – 16 classes • Health hazards – 10 classes • Environmental hazards – 2 classes • Standardization of language • For hazard statements and for precautionary statements

  8. Physical hazard classes 11 Self-Heating Substances 12 Substances Which in Contact with Water Emit Flammable Gases 13 Oxidizing Liquids 14 Oxidizing Solids 15 Organic Peroxides 16 Substances Corrosive to Metal 1 Explosives 2 Flammable Gases 3 Flammable Aerosols 4 Oxidizing Gases 5 Gases Under Pressure 6 Flammable Liquids 7 Flammable Solids 8 Self-Reactive Substances • Pyrophoric Liquids • Pyrophoric solids

  9. Health hazard classes 1 Acute Toxicity 2 Skin Corrosion 3 Skin Irritation 4 Eye Effects 5 Sensitization 6 Germ Cell Mutagenicity 7 Carcinogenicity 8 Reproductive Toxicity 9 Target Organ Systemic Toxicity: Single Exposure & Repeated Exposure 10 Aspiration Toxicity

  10. Environmental Hazard ClassesNot mandated by OSHANot yet required by EPA Acute aquatic toxicity Chronic aquatic toxicity based on fish, crustaceans, algae Hazardous to the ozone layer

  11. Other ClassesSpecific to OSHA Not part of UN GHS Simple asphyxiant such as helium, nitrogen Combustible dust flour dust, grain dust Pyrophoric gases Washburn A Mill, 1878

  12. Material safety data sheet: Really old version Not that you can read this small type...

  13. Material Safety Data Sheet ANSI 16-part Not that you can read this small type...

  14. Safety Data Sheet: GHS version

  15. Safety Data Sheets will still have: • What is it, what’s in it – Section 1 & 3 • What’s the hazard – Section 2 • Emergency info – first aid, fire, spills • Safe use, handling and storage • Recommended PPE • How it behaves • Toxicology • Not mandatory: ecotoxicity, disposal, transport, regulatory

  16. Order will be consistent • Toxicological information • optional • Ecological information • Disposal considerations • Transport information and • Regulatory information. • required • Other information, including date of preparation or last revision. • Identification • Hazard(s) identification • Composition/information on ingredients • First-aid measures • Fire-fighting measures • Accidental release measures • Handling and storage • Exposure controls/personal protection • Physical and chemical properties • Stability and reactivity

  17. SDS Section 2 - acetone Similar to label

  18. Old labels

  19. Labels are changing • Pictograms • Danger or Warning signal words • Hazard statement & Precautionary statement

  20. DOT placard can be used of pictograms on original shipping container

  21. Hazard Statement for a paint thinner Danger: Highly flammable liquid and vapor. May be fatal if swallowed and enters airways. Causes damage to liver or nervous system through prolonged or repeated exposure if inhaled. Causes skin irritation and serious eye irritation. May cause drowsiness or dizziness.

  22. Precautionary Statements for a Thinner (in part) Prevention Keep away from ignition sources such asheat/sparks/open flame Ground/Bond container and receiving equipment. Use only outdoors or in a well-ventilated area. Do not breathe vapors or spray. Wear protective gloves and eye/face protection as specified… Response In case of fire, use a fire extinguisher rated for Class B fires. Do not use water. IF IN EYES: Rinse cautiously with water for several minutes. If eye irritation persists, get medical advice/attention. Wash hands after handling IF ON SKIN: Wash with plenty of soap and water. Take off contaminated clothing and wash before reuse. If skin irritation occurs, seek medical attention. Storage Store container tightly closed in cool, well ventilated place. Store locked up. Disposal Dispose of contents in accordance with local, state, and federal regulations.

  23. Pictograms Meant to quickly convey hazard Always: Diamond black & white, red border Similar to DOT placards Nine types Know what they mean? You probably do

  24. This symbol is used for: • Flammables • Gases under pressure • Things that can hit you • Paddles

  25. Which products would get this symbol? • Muriatic acid • Oxygen • LP gas • Isopropyl alcohol Only application: gases under pressure

  26. Gases under pressure symbol includes: Compressed gases ≥29 psi Liquefied gas Refrigerated liquefied gas Dissolved gas (acetylene)

  27. This symbol is used for: • Fireplaces • Oxidizers • Flammables • Things that you can smoke

  28. Which products would get this symbol? • Acetone • Isopropyl alcohol • Latex paints • Battery acid

  29. Flame symbol is for: Flammable liquids Flammable gases Flammable solids Pyrophorics Self-heating Self-reactive Emit flammable gas Organic peroxides Flammable aerosols, too

  30. Fire Hazard Examples Flammable solids: aluminum powder, magnesium ribbons Pyrophorics: organometallics, silane Self-heating: linseed oil rags Flammable gases: acetylene, hydrogen Self-reactive: acetylene, azides Emit flammable gas: lithium, calcium carbide Organic peroxides: MEK peroxide

  31. Flammable Liquids are divided into categoriesCategory 1 = higher hazard

  32. This symbol means the chemical: • Is surprised • Is highly reactive • Will contribute oxygen and promote fires • Is highly flammable Oxidizer

  33. ? Which products would get this symbol? • Nitric acid • Silica • LP gas • Oxygen Only application: oxidizers

  34. This symbol means the chemical: • Can explode • Decomposes • Will blow up easily • Catches fire easily

  35. ? Which would get this symbol? • Ammunition • Aerosol cans • Fireworks • Acids • Oxygen

  36. Exploding Bomb symbol is for • Explosives • Self-reactives • Organic peroxides Unstable – by themselves, cause violent chemical reaction

  37. ? This symbol means • The fishing’s bad • The chemical is an environmental pollutant • Trees kill fish • You’re a bad fisherman

  38. This symbol means the chemical: • Will cause burns or strong irritation • Will damage pirates who drink it • Is acutely toxic • Will try to take over the world

  39. Skull and Crossbones criteria are different than for consumer products For chemicals that can kill at pretty low doses Won’t apply to many chemicals in commercial use

  40. Acutely Toxic is divided into categoriesCategory 1 = higher hazard

  41. ? This symbol means the chemical: • Can cause acute toxicity • Dissolves metals • Has a pH of 7 or more • Causes skin burns or severe eye irritation

  42. ? Which products would get this symbol? • Battery acid • Isopropyl alcohol • Nitric acid • Carbon monoxide • Amorphous silica

  43. Corrosion symbol is for: Skin corrosion/burns Severe (permanent) eye damage Corrosive to metals pH ≤2, ≥11.5 Not as corrosive irritant

  44. ? This symbol means the chemical can: • Makes your chest explode • Cause long term health harm • Cause cancers • Cause allergic lung reactions (asthma) more than one correct answer

  45. ? This symbol means the chemical is: • An alien that sucks out your lifeblood • A skin penetrant • A specific target organ toxicant • Blow up in your face

  46. The exploding torso is used for: Respiratory sensitizers Mutagens Carcinogens Reproductive toxicants Specific target organ toxicity (single or repeated exposure) Aspiration hazard Serious health hazards, short of death

  47. ? This symbol means the chemical: • Could cause irritation or allergic skin reactions • Can burn intensely • Can cause asthma • Should be listened to

  48. ? This symbol means the chemical could: • Make you a more sensitive, caring person • Rapidly decompose • Give you pimples • Make you dizzy and lightheaded

  49. Exclamation point symbol will be for: Health hazards, but not that severe irritant to eye, skin, breathing skin sensitizers narcotic effects And hazard to ozone layer
