The New Jersey Worker and Community Right to Know Act requires public and private employers to provide information about hazardous substances at their workplaces. (N.J.S.A. 34:5A-1 et. seq.)

Excerpt from ERG Guide 137 [Substances - Water-Reactive - Corrosive]:；EXCEPT FOR ACETIC ANHYDRIDE (UN1715), THAT IS FLAMMABLE, some of these materials may burn, but none ignite readily. May ignite combustibles (wood, paper, oil, clothing, etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. Flammable/toxic gases may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. Substance may be transported in a molten form. (ERG, 2024)

Combustible. Gives off irritating or toxic fumes (or gases) in a fire.

Highly corrosive to skin; [Quick CPC] Liquid causes second or third degree burns after short contact; [CHRIS] Sulfur monochloride is a respiratory irritant with a nauseating odor; it hydrolyzes into HCl and SO2. [ACGIH] Tear drawing. A corrosive substance that can cause pulmonary edema; [ICSC] Sulfur chlorides release HCl, SO2, and H2S when spilled in water; [ERG 2016]

The major hazards encountered in the use and handling of sulfur monochloride stem from its toxicologic properties. Toxic by all routes (ie, inhalation, ingestion, and dermal contact), exposure to this yellowish-red, strong smelling, oily liquid may occur from its use as an intermediate and chlorinating agent in the manufacture of high pressure lubricants and cutting oils, sulfur dyes, and insecticides, as a cross-linking catalyst in polymer technology, as a solvent for sulfur compounds, as a rubber extender, and in the purification of sugar juices. Effects from exposure may include headache, dizziness, nausea, burns to the skin and eyes, shortness of breath, respiratory irritation, pulmonary edema, respiratory distress and failure. OSHA has established a Ceiling limit of 1 ppm as a final standard to become effective December 31, 1992. In activities and situations where over-exposure may occur, wear a self-contained breathing apparatus with a full facepiece, and chemical resistant protective clothing specifically recommended by the shipper or producer. If contact should occur, immediately irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes, and wash exposed skin thoroughly with soap and water. Facilities for quick drenching of the body should be provided in sulfur monochloride work areas. Contaminated clothing should be removed and left at the worksite for cleaning. While sulfur monochloride does not ignite easily, it may ignite other combustible materials (eg, wood, paper, oil). Also, it may create an explosion hazard if its heavier-than-air vapor is allowed to accumulate in confined spaces such as sewers. For fires involving sulfur monochloride, extinguish with dry chemical, CO2, or Halon. Because sulfur monochloride may react with water, use water only if large quantities of combustibles are involved. If water is used, apply it in flooding quantities as spray or fog, from as far a distance as possible. Sulfur monochloride should

Excerpt from ERG Guide 137 [Substances - Water-Reactive - Corrosive]:；Do not touch damaged containers or spilled material unless wearing appropriate protective clothing.

Keep combustibles (wood, paper, oil, etc.) away from spilled material.；SMALL SPILL: Cover with DRY earth, DRY sand or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain. Use clean, non-sparking tools to collect material and place it into loosely covered plastic containers for later disposal. Prevent entry into waterways, sewers, basements or confined areas. (ERG, 2024)

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

Preemployment and periodic examinations should give special emphasis to the skin, eyes, and respiratory system. Pulmonary function tests may be useful. /SRP: for baseline purposes/

The following medical procedures should be made available to each employee who is exposed to hydrogen chloride at potentially hazardous levels: 1. Initial medical examination: A complete history and physical examination: the purpose is to detect existing conditions that might place the exposed employee at increased risk, and to establish a baseline for future health monitoring. Examination of the respiratory system, skin, and eyes should be stressed. -- 14" x 17" chest roentgenogram: Hydrogen chloride causes lung damage. Surveillance of the lung is indicated. -- FVC and FEV (1 sec): Hydrogen chloride is a respiratory irritant. Persons with impaired pulmonary function may be at increased risk from exposure. Periodic surveillance is indicated. 2. Periodic Medical Examination: The aforementioned medical examinations should be repeated on an annual basis, except that an X-ray is necessary only when indicated by the results of pulmonary function testing or by signs and symptoms of respiratory disease. /Hydrochloric acid/

/SIGNS AND SYMPTOMS/ Sulfur monochloride vapors are corrosive and irritating to eyes, nose, and throat, inducing tearing and affecting breathing. Even 2 to 9 ppm in air are irritating to eyes.

/SIGNS AND SYMPTOMS/ It is a fuming, corrosive liquid ... The vapor is irritating to the lung and mucous membrane. In contact with skin, liquid can cause chemical burns.

/SIGNS AND SYMPTOMS/ Symptomatology (after ingestion or skin contact): 1. Corrosion of mucous membranes of mouth, throat, and esophagus, with immediate pain and dysphagia. The necrotic areas are at first grayish white but soon acquire a blackish discoloration and sometimes a shrunken or wrinkled texture; the process is described as a "coagulation necrosis." 2. Epigastric pain, which may be associated with nausea and the vomiting of mucoid and "coffee-ground" material. At times, gastric hemorrhage may be intense, and the vomitus then contains fresh blood. Profound thirst. 3. Ulceration of all membranes and tissues with which the acid comes in contact. After the ingestion of concentrated mineral acid, this corrosion may lead within a few hr or a few days to gastric perforation and peritonitis. 4. Circulatory collapse with clammy skin, weak and rapid pulse, shallow respirations, and scanty urine. Circulatory shock is often the immediate cause of death. 5. Asphyxial death due to glottic edema. 6. Late esophageal, gastric and pyloric strictures and stenoses, which may require major surgical repair, should be anticipated. Signs of obstruction commonly appear within a few weeks but may be delayed for months and even years. Permanent scars may also appear in the cornea, skin and oropharynx. 7. Uncorrected circulatory collapse of several hours' duration may lead to renal failure and ischemic lesions in the liver and heart. /Acids/

/SIGNS AND SYMPTOMS/ As result of its ability to release hydrochloric acid on contact with moisture, this compound is considered to be an upper respiratory tract irritant ... Under some conditions, however, the undecomposed vapor might reach the lungs, in which case it would be more toxic than an equivalent quantity of hydrogen chloride. The above data indicate a considerably greater acute toxicity than that of hydrogen chloride.

Prepared by passing chlorine into molten sulfur, can be purified by fractional distillation.

Disulfur dichloride is generally produced from the elements. In the batch process, chlorine is passed into a solution of sulfur in S2Cl2 with cooling at about 50 - 70 °C until the correct chlorine content is reached. In the continuous process, gaseous chlorine is passed into molten sulfur at 220 - 260 °C, and the gaseous S2Cl2 leaving the reactor is then condensed.

Disulfur dichloride is an intermediate in the production of carbon tetrachloride ... and trichloromethylsulfenyl chloride ... from CS2 and can be obtained from the process as a byproduct.

Sulfur monochloride is made commercially by direct chlorination of sulfur, usually in a heel of sulfur chloride from a previous batch. The chlorination appears to proceed stepwise through higher sulfur chlorides ... If conducted too quickly, the chlorination may yield products containing SCl2 and SxCl2 as well as S2Cl2. A catalyst, eg, iron, iodine, or a trace of ferric chloride, facilitates the reaction. The manufacture in the absence of Fe and Fe salts at 32-100 °C has also been reported.
