First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.

Skin contact

Wash with soap and water. Cover the irritated skin with an emollient. Cold water may be used.

Symptoms: irritated skin

Eye contact

Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Cold water may be used.

Ingestion

Do NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. If large quantities of this material are swallowed, call a physician immediately. Loosen tight clothing such as a collar, tie, belt or waistband.

Immediate Medical Attention

Get medical attention if irritation occurs (eye), if irritation develops (skin), or if inhaled. Call a physician immediately if large quantities are swallowed.

Firefighting Measures

Extinguishing media, specific hazards, and firefighter protection

Suitable media

Not applicable.

Specific hazards

When heated to decomposition it emits toxic fumes of sulfur oxides, hydrogen sulfide, and sodium oxide

Instructions

Not applicable.

06

Accidental Release Measures

Spill cleanup procedures, containment, and environmental protection

Small spill

Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to local and regional authority requirements.

Large spill

Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow to evacuate through the sanitary system.
