First Aid Measures
Emergency procedures for chemical exposure incidents
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Wash with soap and water. Cover the irritated skin with an emollient. Cold water may be used.
Symptoms: irritated skin
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.
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
Not applicable.
When heated to decomposition it emits toxic fumes of sulfur oxides, hydrogen sulfide, and sodium oxide
Not applicable.
Accidental Release Measures
Spill cleanup procedures, containment, and environmental protection
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.
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.
