| Hazards and Protection. | |
| Storage | Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage. |
| Handling | All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood. |
| Protection | Wear appropriate protective gloves, clothing and goggles. |
| Respirators | Wear positive pressure self-contained breathing apparatus (SCBA). |
| Small spills/leaks | Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Use water spray to knock-down vapors. Do not use water on material itself. Neutralize spilled material with crushed limestone, soda ash, or lime. Vapor knockdown water is corrosive or toxic and should be diked for containment. 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. Neutralize with agricultural lime (CaO), crushed limestone (CaCO3) or sodium bicarbonate (NaHCO3). Water spill: Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3). Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates. |

| Stability | Stable at ambient temperature. |
| Incompatibilities | Can react violently with oxidizing agents to form toxic gases Reacts violently with sodium peroxide, chromyl chloride, phosphorus trioxide Reacts exothermically with tin, antimony, antimony sulfide, arsenic sulfide, mercury oxide Reacts particularly violently with dimethyl sulfoxide. |

| Autoignition, °C | 410 | |||
| Fire fighting | Use dry chemical, dry sand, or carbon dioxide. Do not use water on material itself. If large quantities of combustibles are involved, use water in flooding quantities as spray and fog. Use water spray to knock-down vapors. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. | |||
| Fire potential | Sulfur chloride is flammable liquid which gives rise to moderate fire hazard. | |||
| Hazards | Substance will react with water (some violently), releasing corrosiveand/or toxic gases. | |||
| Combustion products | Toxic and corrosive fumes are evolved when heated. | |||

| Exposure effects | Shock, rapid breathing and pulse, circulatory collapse and other changes to pulse, blood pressure, and respirations may occur. Fetotoxicity, developmental abnormalities, and possible resistance to hydrogen chloride by inhalation during pregnancy have been noted. <br>No data were available on the possible effects of hydrogen chloride exposure during lactation. <br>No information about possible male reproductive effects was found in available references. |
| Ingestion | Gastritis, burns, gastric hemorrhage, dilation, edema, necrosis, and strictures may occur. |
| Inhalation | Changes in breathing pattern, irritation, changes in pulmonary function, corrosion and edema of the respiratory tract, chronic bronchitis and noncardiogenic pulmonary edema have been observed. |
| Skin | Burns, ulceration, scarring, blanching, and irritation may occur. |
| Eyes | Dental discoloration or erosion, bleeding gums, corneal necrosis, inflammation of the eye, eye and nasal irritation, nasal ulceration, nose bleeds, throat irritation and ulceration have been observed. |
First aid |
|
| Ingestion | The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation. Activated charcoal activated charcoal binds most toxic agents and can decrease their systemic absorption if administered soon after ingestion. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents. |
| Inhalation | Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols. |
| Skin | Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. |
| Eyes | Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility. |
