硫化アンモニウム

· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.

· ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.

Get medical attention following all overexposures to this compound.

General First Aid:

Extinguish with water, dry chemicals or carbon dioxide.

Do not extinguish fire unless flow can be stopped or safely confined. Use water in flooding quantitites as fog. Solid streams of water may be ineffective. 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.

Separation process which combines liq membrane permeation & conventional steam stripping, effectively removed (NH4)2S from wastewater.

Refinery sour water containing 500-15000 ppm ammonium sulfide is mixed with hydrocarbon emulsion at top of stripping tower at 185 °F & steam is simultaneously passed into bottom of tower. Ammonia is removed with emulsion & hydrogen sulfide is stripped by steam.

Collect and remove with a broom into a large bucket. Dilute with water and neutralize with 6M hydrogen chloride. Drain into a sewer with sufficient water.

Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Absorb bulk liquid with fly ash or cement powder.

Stay upwind. Use water spray to knock down vapor.

Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Do not handle broken packages unless wearing appropriate personal protective equipment.

/SIGNS AND SYMPTOMS/ /It/ manifests ... on all mucous membranes causing conjunctivitis, palpebral edema, keratitis, photophobia & defects of cornea resulting in foggy vision & perception of color rings around lights. It causes ... rhinitis, tracheitis, bronchitis ... & greenish cyanosis. Exposure to high concn results in sudden collapse, convulsions, and death from resp paralysis. With less severe exposure there may be nausea & vomiting & resp becomes depressed. Reactions may be associated with or followed by somnolence, amnesia, unconsciousness, delirium, & hallucinations. The patient may have dysphagia, tachycardia, hypotension, and the urine may contain albumin, casts, and a few red blood cells. The pupils are nonreactive, and there may be strabismus, diplopia, and exophthalmos. The acute poisoning may be followed by bronchitis or pneumonia, bradycardia, myocarditis, cardiac dilatation, peripheral ... /SRP: neuropathy/ and gastrointestinal disturbances. Chronic exposure to low concentrations may cause headache, irritability, insomnia, bradycardia, loss of appetite, nausea, and vomiting. /Sulfides & deriv/

/SIGNS AND SYMPTOMS/ Inhalation of 500 ppm for 30 min produces headaches, dizziness, bronchial pneumonia; 600 ppm for 30 min can cause death. Ingestion causes severe irritation of mucous membranes and stomach. Contact with liquid causes severe burns of eyes & severe skin irritation. May be absorbed through skin & cause hydrogen sulfide poisoning.

/OTHER TOXICITY INFORMATION/ If free gastric acidity is high, the ingestion of these salts may result in their decomp to hydrogen sulfide in stomach with subsequent systemic poisoning. /Alkaline sulfide salts/

/LABORATORY ANIMALS: Acute Exposure/ In addition to increased ventilation, small parenteral doses of sulfide in lab animals produce fleeting rise followed by profound (perhaps irreversible) fall in blood pressure. Death ... is invariably result of central resp paralysis. /Hydrogen sulfide/

According to the 2006 TSCA Inventory Update Reporting data, the number of persons reasonably likely to be exposed in the industrial manufacturing, processing, and use of diammonium sulfide is 1000; the data may be greatly underestimated(1).

NIOSH (NOES Survey 1981-1983) has statistically estimated that 4,271 workers (1,482 of these were female) were potentially exposed to diammonium sulfide in the US(1). Occupational exposure to diammonium sulfide may occur through inhalation and dermal contact with this compound at workplaces where diammonium sulfide is produced or used. Use data indicate that the general population may be exposed to diammonium sulfide via ingestion of food and dermal contact with consumer products containing diammonium sulfide(SRC).

Emergency and supportive measures: NOTE: Rescuers should use self-contained breathing apparatus to prevent personal exposure. Maintain on open airway and assist ventilation if necessary. Administer high-flow humidified supplemental oxygen. Observe for several hours for delayed-onset chemical pneumonia or pulmonary edema. Treat coma, seizures, and hypotension if they occur. /Hydrogen sulfide/

Decontamination. Remove the victim from exposure and give supplemental oxygen, if available. /Hydrogen sulfide/

Enhanced elimination. There is no role for enhanced elimination procedures. Although hyperbaric oxygen therapy has been promoted for treatment of hydrogen sulfide poisoning, this is based on anecdotal cases, and there is no convincing rationale or scientific evidence for its effectiveness. /Hydrogen sulfide/

Inhalation of corrosive gases (eg, chlorine and ammonia) may cause upper respiratory tract injury, with stridor, hoarseness, wheezing, and noncardiogenic pulmonary edema. Pulmonary symptoms may be delayed after exposure to gases with low water solubility (eg, nitrogen dioxide and phosgene). /Caustic and corrosive agents/

Ammonium sulfide is a food additive permitted for direct addition to food for human consumption, as long as 1) the quantity added to food does not exceed the amount reasonably required to accomplish its intended physical, nutritive, or other technical effect in food, and 2) when intended for use in or on food it is of appropriate food grade and is prepared and handled as a food ingredient.

Persons in charge of vessels or facilities are required to notify the National Response Center (NRC) immediately, when there is a release of this designated hazardous substance, in an amount equal to or greater than its reportable quantity of 100 lb or 45.4 kg. The toll free number of the NRC is (800) 424-8802. The rule for determining when notification is required is stated in 40 CFR 302.4 (section IV. D.3.b).

Ammonium sulfide is designated as a hazardous substance under section 311(b)(2)(A) of the Federal Water Pollution Control Act and further regulated by the Clean Water Act Amendments of 1977 and 1978. These regulations apply to discharges of this substance. This designation includes any isomers and hydrates, as well as any solutions and mixtures containing this substance.
