Hazards and Protection.
Store in accordance with all current regulations and standards.
Handle in accordance with all current regulations and standards.
Wear appropriate chemical protective clothing and gloves. Wear splash resistant safety goggles with a faceshield. Provide an emergency eye wash fountain and quick drench shower in the immediate work area.
Wear positive pressure self-contained breathing apparatus.
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors.
Keep away from bases and oxidizing materials.

Do not extinguish fire unless flow can be stopped. Do not apply water to point of leak in tank car or container. Use water in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use alcohol foam, dry chemical or carbon dioxide.
Flammable; may be ignited by heat, sparks or flames. May form explosive mixtures with air.
Flammable; may be ignited by heat, sparks or flames. May form explosive mixtures with air. May polymerize explosively when heated or involved in a fire. Vapors from liquefied gas are initially heavier than air and spread along ground. Vapors may travel to source of ignition and flash back. Some of these materials may react violently with water. Containers may explode when heated. Ruptured cylinders may rocket. Runoff may create fire or explosion hazard.
Fire will produce irritating, corrosive and/or toxic gases.
Nausea and vomiting may be noted. Weight loss can be seen with chronic exposure.
Respiratory depression, cyanosis, pulmonary edema, bronchitis, and dyspnea may be noted following exposure to non-fatal concentrations.
Skin exposure may result in severe pain, itching, and erythema, especially in moist areas. Cyanosis may be noted following severe exposure.
Contact may cause burns, severe injury and/or frostbite.
Hydrogen sulfide is a gas at room temperature making ingestion unlikely.
Immediately move patient to fresh air and administer 100 percent oxygen. Prevent self-exposure and possible death by wearing a self-contained breathing apparatus to rescue the victim.
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
Immediately flush with running water for at least 20 minutes.
