Section IV – First Aid Measures

Description of first aid measures

Eye Contact: Immediate medical attention is required. Take victim immediately to hospital. Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Rinse the eyes with a calcium gluconate 1 % solution in physiological serum (10 ml of calcium gluconate 10% in 90 ml of physiological serum). In the case of difficulty of opening the lids, administer an analgesic eye wash (oxybuprocaine).

Skin Contact: Call a physician immediately. Take victim immediately to hospital. Take off contaminated clothing and shoes immediately. Wash off with plenty of water. Immediately apply calcium gluconate gel2.5o/o and massage into the affected area using rubber gloves; continue to massage while repeatedly applying gel until 15 minutes after pain is relieved. If fingers/finger nails are touched, even if there is no pain, dip them in a bath of 5% calcium gluconate for 15 to 20 minutes. Keep warm and in a quiet place. e.

Inhalation: In case of accident by inhalation: remove casualty to fresh air and keep at rest. Oxygen or artificial respiration if needed. Victim to lie down in the recovery position, cover and keep him warm. Call a physician immediately. Take victim immediately to hospital.

Ingestion: Call a physician immediately. Take victim immediately to hospital. If victim is conscious. lf swallowed, rinse mouth with water (only if the person is conscious). Give to drink a 1% aqueous calcium gluconate solution, Do NOT induce vomiting. Artificial respiration and/or oxygen may be necessary. lf victim is unconscious but breathing: Oxygen or artificial respiration if needed.

Potential Effects of Exposure

See Section 11 for more information


Section V – Fire Fighting Measures

Suitable Extinguishing Media

Use an extinguishing agent suitable for the surrounding fire.

Unsuitable Extinguishing Media: No data available.

Specific Hazards Arising from the Chemical

Hazardous decomposition products formed under fire conditions. – Hydrogen fluoride, and oxides of sulfur.

Protective Equipment and Precautions for Firefighters

Wear self-contained breathing apparatus and protective suit. – Fire fighters must wear fire resistant personnel protective equipment. – Wear chemical resistant over suit – Protect intervention team with a water spray as they approach the fire. Cool containers / tanks with water spray. Keep from any possible contact with water. Approach from upwind. Suppress (knock down) gases/vapors/mists with a water spray jet. After the fire, proceed rapidly with cleaning

of surfaces exposed to the fumes in order to limit equipment damage.


Section VI –Accidental Release Measures


Personal Precautions, Protective Equipment and Emergency Procedures

Eliminate all ignition sources (no smoking, flares, sparks or flames in the immediate area). Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Do not get water inside the containers. Approach from upwind. Isolate the area. Wear self-contained breathing apparatus in confined spaces, in cases where the oxygen level is depleted, or in case of significant emissions. Prevent further leakage or spillage if safe to do so. Keep away from incompatible products. Suppress (knock down) gases/vapors/mists with a water spray jet. Avoid spraying the leak source. Protect intervention team with a water spray as they approach the fire.

Methods and Material for Containment and Cleaning Up
