Emergency First Aid Measures
Critical first aid procedures for chemical exposure incidents and medical emergencies
🫁 Inhalation Exposure
If breathed in, move person into fresh air. If not breathing give artificial respiration. Consult a physician.
🖐️ Skin Contact
Wash off with soap and plenty of water. Consult a physician.
👁️ Eye Contact
Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.
🍽️ Ingestion/Swallowing
Do NOT induce vomiting. Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.
Fire Fighting Measures & Emergency Response
Fire suppression methods, extinguishing media, and firefighting safety procedures
✅ Suitable Extinguishing Media
For small (incipient) fires, use media such as "alcohol" foam, dry chemical, or carbon dioxide. For large fires, apply water from as far as possible. Use very large quantities (flooding) of water applied as a mist or spray; solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water.
🛡️ Firefighter Protection Equipment
Wear self contained breathing apparatus for fire fighting if necessary.

😷 Respiratory Protection
Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).
🦺 Skin/Body Protection
Choose body protection according to the amount and concentration of the dangerous substance at the work place.
