Work environment Risky Materials Data Framework (WHMIS)

Presentation Transcript

  1. Workplace Hazardous Materials Information System (WHMIS)

  2. “No employer may allow the use, handling or storage of a Controlled Productin a workplace unless the product carries a label and a material safety data sheet which meet the requirements of this Act and the regulations and unless the worker has received the training and information required to carry out the work entrusted to him safely”- Article 62.1, An Act respecting occupational health and safety R.S.Q., S-2.1

  3. What are Controlled Products? Class A: Compressed Gas Class B: Flammable and Combustible Material

  4. Controlled Products Class C: Oxidizing Material

  5. Class D Controlled Products Division 1: Materials Causing Immediate and Serious Toxic Effects Division 2: Materials Causing Other Toxic Effects Division 3: Biohazardous Infectious Materials

  6. Controlled Products Class E: Corrosive Material Class F: Dangerously Reactive Material

  7. Not Classified as Controlled Products: explosives radioactive materials

  8. Not Classified as Controlled Products: domestic goods cosmetics

  9. Not Classified as Controlled Products: Food & food additives Drugs & diagnostic chemicals

  10. Not Classified as Controlled Products: pesticides hazardous waste

  11. DIMETHYL MEGADEATH WHMIS Main Elements • Labels • supplier • workplace • laboratory • Material safety data sheets • supplier • workplace • Training • core • job specific

  12. Supplier’s Label TOLUENE SULFONIC ACID PRODUCT IDENTIFIER RISK PHRASES: Highly irritating to skin, eyes, and nose HEALTH HAZARD DATA: Strong Acid: Treat as sulphuric acid EFFECTS OF OVEREXPOSURE: ACUTE ABC Chemicals 123 Chemical Drive Chemical City 1-800-CHE-MICAL Supplier identifier PRECAUTIONARY MEASURES: PERSONAL PROTECTIVE EQUIPMENT EYE: Face shield and goggles GLOVES: Rubber OTHER CLOTHING AND EQUIPMENT: Rubber apron, rubber boots FIRST AID: EYES: Flush with water for 15 minutes. Consult with physician SKIN: Flush with water as per sulphuric acid INGESTION: Treat as per sulphuric acid. Consult with physician Refer to Material Safety Data Sheet FRANCAIS AU VERSO

  13. Workplace Label Methyl Alcohol PRODUCT IDENTIFIER Precautions: Use in well ventilated area Avoid contact with skin and eyes Keep away from spark and flame Refer to Material Safety Data Sheet FRANCAIS AU VERSO

  14. Workplace Labels Required: • On controlled products produced and used in the workplace, • if the label becomes illegible. • received from a supplier and transferred to another container* *not required if transferred material is used in its entirety prior to the end of the work shift

  15. Workplace Labelsin Research Labs • MSDS must be available • Not to be transported out of lab • Product identifier (name) Agent Green

  16. Material Safety Data Sheets • Supplier must provide • Accessible to ALL workers in the workplace • Must be kept up to date • Must be made available to doctor in the event of exposure

  17. What’s in an MSDS? 1. Product Information Item Name: VARSOL-1 SOLVENT Company's Name: EXXON CO, 800 BELL ST., HOUSTON, TX, US, 77252-2180 Emerg Ph #: 713-656-3424 /800-424-9300(CHEMTREC) Part Number: 131030-00627

  18. What’s in an MSDS? 2. MSDS Preparation Date MSDS Prepared: 12APR95 Safety Data Review Date: 13JUN96 MSDS Preparer's Name: MARKETING TECHNICAL SER Preparer's Company: EXXON COMPANY, USA (713-656-5949)

  19. What’s in an MSDS? 3. Ingredients Ingredient: STODDARD SOLVENT Ingredient Sequence Number: 01 Percent: 100 CAS Number: 8052-41-3 OSHA PEL: 500 PPM ACGIH TLV: 100 PPM

  20. Definition: Threshold Limit Value • TLV (TWA) is an 8-hour time-weighted average believed to be the average concentration to which most workers can be exposed during an 8-hour workday, day after day, without harmful effects. • TLV (STEL) is a 15 minute “short term exposure limit” • Ceiling (C) is a maximum concentration never to be exceeded

  21. Stoddard Solvent? Ingredient: C*7-C*10 saturated hydrocarbon, Percent: 83.0 Ingredient: 1,2,4-trimethylbenzene. Percent: 4.0 Ingredient: C8+ aromatics, Percent: 17.0

  22. What’s in an MSDS? 4. Physical Properties Appearance and Odor: clear water-white liquid, mineral spirits odor. Boiling Point: 315F,157C Melting Point: <0F,<-18C Vapor Pressure (MM Hg/70 F): 1.6MM @20C

  23. What’s in an MSDS? 4. Physical Properties (cont’d) Vapor Density (Air=1): 3.5 Specific Gravity: 0.80 Evaporation Rate And Ref: 0.1 (N-butyl acetate=1) Solubility In Water: negligible Percent Volatiles By Volume: 100 pH: NEUTRAL

  24. What’s in an MSDS? 5. Fire and Explosion Data Flash Point: 104F,40C Flash Point Method: TCC Lower Explosive Limit: 2.1% Upper Explosive Limit: 13.3%

  25. Definition: Flash Point • The flash point is the lowest temperature at which a liquid produces enough vapour to ignite in the presence of a source of ignition. • The lower the flash point, the greater the risk of fire.

  26. Flash Points oC acetone -18 ether (diethyl) -45 natural gas - 88 ethyl alcohol 13 methyl alcohol 11 gasoline -43 varsol 40

  27. What’s in an MSDS? 5. Fire and Explosion Data, cont’d Extinguishing Media: foam, H2O spray(fog), dry chem, CO2 Special Fire Fighting Proc: keep fire-exposed containers cool w/H2O Unusual Fire And Expl Hazards: liq is volatile/gives off invisible vapour; may settle in low areas

  28. What’s in an MSDS? 6. Product Reactivity Stability: YES Cond To Avoid: keep product away from ignition sources such as heat,sparks,pilot lights,static electricity, open flames. Materials To Avoid: strong oxidants e.g., chlorine; O2, sodium and calcium hypochlorite.

  29. What’s in an MSDS? 6. Product Reactivity • Hazardous Decomposition Products: fumes, smoke, CO, sulfur oxides, aldehydes • Hazardous Polymerization?: NO

  30. What’s in an MSDS? 7. Toxicological information LD50-LC50 Mixture: ORAL LD50 (RABBIT) >3.16G/KG OF BODY WT Route Of Entry - Inhalation: YES Route Of Entry - Skin: YES Route Of Entry - Ingestion: NO

  31. Definition: LD50 • LD50 (Lethal Dose50) is the amount of a substance that, when administered by a defined route of entry (e.g. oral or dermal) over a specified period of time, is expected to cause the death of 50 per cent of a defined animal population.
