                First Aid Measures

                Ingestion
                Give water; induce vomiting; call a doctor.
                Inhalation
                Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
                Skin
                Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush with running water for at least 20 minutes.
                Eyes
                In case of contact with substance, immediately flush with running water for at least 20 minutes.

                Handling and Storage

                Storage
                Protect against physical damage. Separate from acids, oxidizing materials, and possible sources of ignition.
                Handling
                Containers of this material may be hazardous when emptied. Since emptied containers retain product residues (vapor, liquid, and/or solid), all hazard precautions given in the data sheet must be observed.

                Hazards Identification

                Inhalation
                Stridor, dyspnea, upper airway injury, and pulmonary edema, especially following inhalation of vaporized caustics, may occur.
                Skin
                Severe skin irritation and/or burns may occur.
                Eyes
                See Skin.
                Ingestion
                Burns of the esophagus and less commonly the stomach may occur after caustic ingestion; the absence of oral mucosal injury does not reliably exclude esophageal burns. Patients with stridor, drooling or vomiting are more likely to have esophageal burns.
                Hazards
                When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards. May polymerize explosively when heated or involved in a fire. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.

                Exposure Controls/Personal Protection

                Personal Protection
                Goggles or face shield. Wear special protective clothing and positive pressure self-contained breathing apparatus.
                Respirators
                Wear positive pressure self-contained breathing apparatus (SCBA).
                Exposure Effects
                Patients may acutely present with low heart rate, rapid heart rate, hyperventilation, respiratory depression even to the point of apnea, and/or hypo-/elevated blood pressure. Asphyxial seizures, coma, and death associated with rapid respiratory paralysis may be noted following exposure to high concentrations. Headache, sweating, vertigo, anosmia, irritability, staggering gait, disorientation, somnolence, weakness, confusion, and delirium may be noted following exposure to non-fatal levels. Spontaneous abortions have occurred after exposure to life-threatening concentrations.

                Fire Fighting Measures

                Fire Fighting
                Flood with water.
                Fire Potential
                May burn but does not ignite readily.

                Accidental Release Measures

                Small spills/leaks
                Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard.

                Stability and Reactivity

                Incompatibilities
                Liberates toxic hydrogen sulfide on contact with acids. Reacts violently with carbon; diazonium salts; n,n-dichloromethylamine; 0-nitroaniline diazonium salt; water. Reacts with acid more vigorously, producing corrosive solutions and hydrogen sulfide.
                Stability
                Unstable - can explode with shock or heat reactive at high temperature or pressure.
                Decomposition
                When heated to decomposition, emits toxic fumes of sulfur oxides and disodium oxide.
                Combustion Products
                Irritating sulfur dioxide is produced in fire.
