  Personal Protective Equipment (PPE)

  • Specify the required PPE, including:
    • Safety glasses or face shield
    • Impervious gloves (e.g., nitrile or neoprene)
    • Lab coat or apron
    • Closed-toe shoes

  Handling Procedures

  • Emphasize the importance of working in a well-ventilated area or under a fume hood.
  • Stress the need to handle NaH under an inert atmosphere (nitrogen or argon) to prevent reaction with air and moisture.
  • Describe the proper techniques for dispensing and transferring NaH, using specialized equipment if necessary (e.g., syringe techniques under inert gas).
  • DO NOT use water to clean up spills.

  Storage

  • Specify the storage conditions:
    • Store in a tightly sealed container under an inert atmosphere.
    • Store in a cool, dry, and well-ventilated area, away from incompatible materials.
    • Keep away from sources of ignition.

  Disposal

  • Describe the proper disposal methods, which often involve quenching the NaH with a controlled reaction with a suitable reagent (e.g., isopropanol) under controlled conditions.
  • Emphasize the importance of following local and national regulations for hazardous waste disposal. Consider consulting a qualified waste disposal service.
  • Illustrative Example: Controlled quenching of NaH with isopropanol:
  • • Slowly add isopropanol to a mixture of NaH in a suitable inert solvent (like mineral oil) under continuous stirring.
  • • Monitor the reaction for gas evolution (hydrogen).
  • • Once the reaction is complete, the mixture can be neutralized and disposed of as per local regulations. This should only be carried out by trained personnel.

  First Aid Measures

  • Provide instructions for first aid in case of accidental exposure:
    • Skin Contact: Immediately wash the affected area with plenty of water for at least 15 minutes. Seek medical attention.
    • Eye Contact: Immediately flush the eyes with plenty of water for at least 15 minutes, holding the eyelids open. Seek medical attention.
