3. Surgical or wound disinfection: spray the wound with 1% mist or wash it with 0.05% water solution.

4. Surgical instruments disinfection: soak with 0.1% water solution. (Add 0.5% sodium nitrite to prevent the instruments from rusting.) The instrument can be soaked in a 0.02% water solution for storing purposes. (Also add 0.1% sodium nitrite.) The water solution should be changed every two weeks.

5. Burns and scalding: 0.5% mist spray or scream.
