Never give anything by mouth to an unconscious person.
Note to Physicians:
Treat symptomatically.

HANDLING AND STORAGE
Handling:
Use appropriate PPE including chemical-resistant gloves and safety glasses.
Avoid prolonged skin contact and avoid splashing into eyes.
Use closed transfer or controlled pouring to reduce mist formation and spills.
Ventilation:
