Ask Dr Safety about Reactives

  1. 1. ASK Dr SAFETY Reactive and Air/Water Sensitive Chemicals
  2. 2. Ask Dr. Safety Neal Langerman Advanced Chemical Safety Harry Elston Midwest Chemical Safety
  3. 3. Avoid these numbers! The average number of chemical  2 accidents every day  Percent of chemical accidents which  6 result in death  Every 45 days there is a major  45 chemical accident   Million dollars of property damage  600 resulted from major chemical accidents  1980‐01  Thousand dollars is the average cost for a  15 single workers compensa7on claim  For details on sources, please see the business case.
  4. 4. What we are talking about   Pyrophoric •  Silane •  Metal alkyls (t-Butyl Lithium)   Air/Moisture Sensitive •  Alkali metals •  Organic halides (Acetyl chloride) •  Metal hydrides (Lithium Aluminum Hydride) Advanced Chemical Safety www.chemical-safety.com Lab RAT Pyrophorics Solutions@chemical-safety.com
  5. 5. Information Sources •  Bretherick's Handbook of Reactive Chemical Hazards [Urben 2006] •  Sax's Dangerous Properties of Industrial Materials [Lewis 2004] •  NOAA Chemical Reactivity Worksheet (discussed later in this section) - (http://response.restoration.noaa.gov/chemaids/react) •  International Chemical Safety Cards (accessible from CDC website at (http://www.cdc.gov/niosh/ipcs/icstart.html) •  NIOSH Pocket Guide to Chemical Hazards (online version available at (http://www.cdc.gov/niosh/npg/npg.html) •  NFPA Fire Protection Guide to Hazardous Materials [NFPA 2002] •  Coast Guard Hazardous Information System (http://www.chrismanual.com) •  Data from manufacturers/suppliers, including Material Safety Data Sheets (MSDSs) •  For more information on the OSHA alliance, visit: (www.osha.gov/dcsp/ alliances/reactives/reactives) Chemical Reactivity Hazards Page 5
  6. 6. Hazmat Explorer = Chemical Safety Hazmat Explorer is an authorita7ve online resource for  chemical safety informa7on for chemists who need to  avoid chemical accidents.  •  Quickly find and isolate high‐quality chemical safety informaEon  •  Reduce the likelihood of accidents, injuries and harm to the  environment  •  Save Eme with the ability to search by chemical sub‐structure  and similarity as well as chemical name, molecular formula and  CAS number  •  Be able to link directly to associated material to make efficient  and effecEve chemical safety decisions 
  7. 7. Complete & Robust Content Hazmat Explorer  A reliable, easy‐to‐use source of  industrial chemical safety  Browse and Search  informaEon. Core content:   by text and/or chemical  structure  5 Leading book titles  Extensive Linking  Reactive Link to Scopus and  5,000 chemical ScienceDirect ‐ connecEng  hazards through to primary content  and based on chemical  idenEficaEon  2,200 Chemical regulations 1,000 Flammability records Entries on 700 toxicology dangers
  8. 8. Sneak Peek From start to finish, the research process takes mere seconds to deliver the information you need —when and where you 8 need it.
  9. 9. HANDLING AIR SENSITIVE CHEMICALS   Syringe method •  50 ml in a 100 ml gas tight syringe, MAX •  Single use syringe   Double-ended needle method •  Larger volumes   Glove box •  Best choice Advanced Chemical Safety www.chemical-safety.com Lab RAT Pyrophorics Solutions@chemical-safety.com
  10. 10. Lab Rat Advanced Chemical Safety www.chemical-safety.com Lab RAT Pyrophorics Solutions@chemical-safety.com
  11. 11. Handling   Experimental Set-up •  Gloves can be •  “Pilots Gloves” •  Kevlar •  Leather •  Nitrile (thin mil) under, if desired •  Gas tight syringe, 15 – 60 cm SS needle (NOTE: photo is example setup; done by John Palmer at UCSD) Advanced Chemical Safety www.chemical-safety.com Lab RAT Pyrophorics Solutions@chemical-safety.com
  12. 12. Handling   Second Person Essential   Fire retardant clothing   Faceshield/Proper us of sash   Clear work space   Adequate fire suppression   Clear understanding of task
  13. 13. Handling   Lab is fully equipped and experienced in handling pyrophoric liquids   Lab has a detailed, well-tested written procedure •  If these BOTH are not met, should the task be done?
  14. 14. IDENTIFYING REACTIVE HAZARDS Reactive Metal & Solvent Fire
