Guidance on Safe Use

First-aid measures

4.1	Description of first aid measures
General information
Remove contaminated clothing and shoes immediately, and launder thoroughly before reusing. In case of accident or if you feel unwell, seek medical advice immediately. If the patient is likely to become unconscious, place and transport in stable sideways position.
After inhalation
Remove affected person from the immediate area. Ensure supply of fresh air. Irregular breathing/no breathing: artificial respiration. Call a doctor immediately.
After skin contact
When in contact with the skin, clean with soap and water.
After eye contact
