  • All containers are clearly labeled with the identify of the HHC

  • Designated storage and use locations within laboratory have signage identifying the HHC hazards present in those locations.

Medical Attention and First Aid

  • Laboratory personnel should seek medical attention when:
    - signs or symptoms associated with a hazardous chemical exposure are experienced, or
    - exposure monitoring reveals an exposure level routinely above acceptable levels, or
    - a spill, leak, explosion or other event results in the likelihood of a hazardous expsoure.

  • Emergency medical provider:

  • Location:

  • Contact information:

  • Are specific first aid supplies/procedures required (e.g., antitoxin) for work with this material? If yes, document the the specific procedures to be followed post-exposure.

Decontamination

  • List all required supplies/equipment with locations:

Waste Management and Disposal

  • Identify waste management methods for all research and waste by-products associated with this HHC:

  • Chemical wastes are collected and disposed as hazardous waste via EHS, including chemically-contaminated sharps.

  • Neutralization or deactivation in laboratory prior to disposal

  • Describe method - this option requires EHS pre-approval

  • HHC is EPA acutely toxic chemical. Collect sharps and used containers as hazardous waste.

  • Other disposal method

  • Describe method - this option requires EHS pre-approval

  • Chemical waste storage location

Training

  • All laboratory personnel must at a minimum completed safety training on an annual basis. Additionally, laboratory personnel who handle or use the High Hazard Substance must demonstrate specific competency and familiarity regarding the safe handling and use of this HHC prior to purchase or use. The Principal Investigator is responsible for ensuring all laboratory personnel handling and using this HHC are trained in the following:

  • Review of HHC Checklist and associated documentation including Exposure Controls and PPE

  • Review Safety Data Sheets including signs and symptoms of exposure

  • Hands-on training with the Principal Investigator or other knowledgeable an experienced senior laboratory staff member on the safe handling and use of the HHC

  • New personnel must work under close supervision of Principal Investigator or other knowledgeable and experienced laboratory staff member.
