First Aid Measures
Emergency procedures for chemical exposure incidents
Upon breathing difficulties or irritation of the respiratory tract: Bring the person into fresh air and stay with him/her.
Symptoms: irritation of the respiratory tract
Flush exposed area with water for a long time – at least 30 minutes. It may be necessary to flush for several hours. Use a comfortable water temperature (20-30 °C). Contact Poison Information/doctor/hospital for further advice on follow-up and treatment. Upon irritation: rinse with water. In the event of continued irritation, seek medical assistance.
Symptoms: skin corrosive properties, irreversible effects
If in eyes: Flush eyes with plenty of water or salt water (20-30 °C) for at least 30 minutes and continue until irritation stops. Remove contact lenses. Make sure you flush under the upper and lower eyelids. Seek medical assistance immediately and continue flushing during transport.
Symptoms: irreversible effects
In the case of ingestion, contact a doctor immediately. If the person is conscious, give them water. DO NOT try to induce vomiting unless this is recommended by a doctor. Hold head facing down to prevent vomit from returning to the mouth and throat. Prevent shock by keeping the injured person warm and calm. Initiate immediate resuscitation if breathing stops. If unconscious, roll the injured person into recovery position. Call an ambulance.
Immediate Medical Attention
Get immediate medical advice/attention.
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
Alcohol-resistant foam, carbon dioxide, powder, water mist.
Waterjets should not be used, since they can spread the fire.
Fire will result in dense smoke. Exposure to combustion products may harm your health.
Closed containers, which are exposed to fire, should be cooled with water.
Firefighter Protection
Wear self-contained breathing apparatus and protective clothing to prevent contact.
Accidental Release Measures
Spill cleanup procedures, containment, and environmental protection
Storages not yet ignited must be cooled by water mist. Remove flammable materials if conditions allow it. Ensure sufficient ventilation. Avoid direct contact with spilled substances. Ensure adequate ventilation, especially in confined areas. Contaminated areas may be slippery.
Avoid discharge to lakes, streams, sewers, etc.
Limit spillage and collect using granular absorbent or similar materials. Contain and collect spillage with non-combustible, absorbent material. Cleaning should be performed with normal cleaning agents.
Materials: granular absorbent or similar materials, sand, earth, vermiculite or diatomaceous earth
