First Aid Measures：

Reactivity Profile：
SULFUR MONOCHLORIDE poses a fire hazard in contact with organic matter. Can react violently with oxidizing agents to form toxic gases. Reacts violently with sodium peroxide, chromyl chloride, phosphorus trioxide. Emits highly toxic fumes of sulfur oxides and chlorides when heated to decomposition [Lewis, 3rd ed., 1993, p. 1196]. Reacts exothermically with tin, antimony, antimony sulfide, arsenic sulfide, mercury oxide. A mixture with potassium is shock-sensitive and explodes violently on heating [Mellor, 1947, 10, p.642]. Reacts particularly violently with dimethyl sulfoxide [Buckley, A., J. Chem. Ed., 1965, 42, p. 674].
Signs and Symptoms：
irritation eyes, skin, mucous membrane; lacrimation (discharge of tears); cough; eye, skin burns; pulmonary edema
Storage Conditions：
Aldehydes and epoxides in the presence of hydrochloric acid cause violent polymerization. Alcohol and glycols in the presence of hydrochloric acid lead to dehydration reactions. /Hydrochloric acid/
Exposure Prevention：
AVOID ALL CONTACT!
Firefighting Hazards：
Confined fires with high fuel loads of polyvinyl chloride, such as a fire in a vault with a high load of polyvinyl chloride-coated electrical wiring, may generate sufficient hydrogen chloride to cause irritation in fire fighters. Rapid combustion of relatively large amt of polymer may yield ... hydrogen chloride ... . /Hydrochloric acid/
Ingestion Prevention：
Do not eat, drink, or smoke during work.
Medical Surveillance：
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 aforemen...
Inhalation Prevention：
Use ventilation, local exhaust or breathing protection.
NIOSH Recommendations：
Recommended Exposure Limit: Ceiling value: 1 ppm (6 mg/cu m).
Nonfire Spill Response：
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)
Air and Water Reactions：
Based on a scenario where the chemical is spilled into an excess of water (at least 5 fold excess of water), half of the maximum theoretical yield of Hydrogen Chloride gas will be created in 1.8 minutes. Experimental details are in the following: "Development of the Table of Initial Isolation and Protective Distances for the 2008 Emergency Response Guidebook", ANL/DIS-09-2, D.F. Brown, H.M. Hartmann, W.A. Freeman, and W.D. Haney, Argonne National Laboratory, Argonne, Illinois, June 2009.
Packaging and Labelling：

Fire Fighting Procedures：
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty). 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. /Hydrochloric acid/
Isolation and Evacuation：
FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2024)
