安全保管Separated from food and feedstuffs and incompatible materials. Dry. Well closed. Keep in a well-ventilated room. Store in an area without drain or sewer access.
暴露管理・個人防護· Wear positive pressure self-contained breathing apparatus (SCBA).TIH (Toxic Inhalation Hazard) - Term used to describe gases and volatile liquids that are toxic when inhaled. Some are TIH materials themselves, e.g., chlorine, and some release TIH gases when spilled in water, e.g., chlorosilanes. [ERG 2016].
消火手順If material on fire or involved in fire: Do not extinguish fire unless flow can be stopped. Use water in flooding quantities 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.
清掃方法Environmental considerations- land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Absorb bulk liquid with fly ash, cement powder, or commercial sorbents.Environmental considerations- water spill: Use natural barriers or oil spill control booms to limit spill travel. Remove trapped material with suction hoses.Environmental considerations- air spill: Apply water spray or mist to knock down vapors.
非火災時の漏出対応Excerpt from ERG Guide 156 [Substances - Toxic and/or Corrosive (Combustible / Water-Sensitive)]:
処分方法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 qualitypotential migration in soil or watereffects on animal, aquatic, and plant lifeand conformance with environmental and public health regulations.
漏出処分Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Collect leaking and spilled liquid in sealable dry containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer.
Preventive MeasuresIf material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors.Personnel protection: Avoid breathing vapors. Keep upwind. ... Avoid bodily contact with the material. ... Do not handle broken packages unless wearing appropriate personal protective equipment Wash away any material which may have contacted the body with copious amounts of water or soap and water.SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

環境中動態TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 6.1(SRC), determined from a structure estimation method(2), indicates that methanesulfonyl chloride is expected to have very high mobility in soil(SRC). Volatilization of methanesulfonyl chloride from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 4.4X10-5 atm-cu m/mole(SRC), using a fragment constant estimation method(3). Methanesulfonyl chloride is expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 3.1 mm Hg(SRC), determined from a fragment constant method(4). Biodegradation data were not available(SRC, 2007).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 6.1(SRC), determined from a structure estimation method(2), indicates that methanesulfonyl chloride is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 4.4X10-5 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 15 hours and 11 days, respectively(SRC). According to a classification scheme(5), an estimated BCF of 1.9(SRC), from an estimated log Kow of 1.3(SRC) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Methanesulfonyl chloride hydrolyzes slowly in water(7). Biodegradation data were not available(SRC, 2007).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), methanesulfonyl chloride, which has an estimated vapor pressure of 3.1 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase methanesulfonyl chloride is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be 150 days(SRC), calculated from its rate constant of 1.1X10-12 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Methanesulfonyl chloride does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight(4).

Signs and SymptomsCough. Sore throat. Burning sensation. Laboured breathing. Shortness of breath.Redness. Pain. Blisters.Redness. Pain. Severe burns.See Inhalation.
ICSC Environmental DataThe substance is harmful to aquatic organisms.
Soil Adsorption/MobilityUsing a structure estimation method based on molecular connectivity indices(1), the Koc of methanesulfonyl chloride can be estimated to be 6.1(SRC). According to a classification scheme(2), this estimated Koc value suggests that methanesulfonyl chloride is expected to have very high mobility in soil.
Human Toxicity Excerpts/SIGNS AND SYMPTOMS/ Methanesulfonyl chloride is corrosive to eyes, skin, and mucous membranes.
Artificial Pollution SourcesMethanesulfonyl chloride's production and use in flame-resistant products, as a stabilizer for liquid sulfur trioxide, as a biological chemical, as a chemical intermediate(1) in the photographic, fiber dye, agricultural, and pharmaceutical industries, a catalyst, curing agent, and chlorinating agent(2) may result in its release to the environment through various waste streams(SRC).
Environmental BioconcentrationAn estimated BCF of 1.9 was calculated for methanesulfonyl chloride(SRC), using an estimated log Kow of 1.3(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Volatilization from Water/SoilThe Henry's Law constant for methanesulfonyl chloride is estimated as 4.4X10-5 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that methanesulfonyl chloride is expected to volatilize from water surfaces(2). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 15 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 11 days(SRC). Methanesulfonyl chloride's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Methanesulfonyl chloride is expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 3.1 mm Hg(SRC), determined from a fragment constant method(3).
Non-Human Toxicity Excerpts/LABORATORY ANIMALS: Acute Exposure/ The 1-hr and 4-hr inhalation LC50 values in rats were approximately 200 ppm and 25 ppm, respectively. Clinical signs during exposure included salivation and marked eye and respiratory tract irritation. Effects noted postexposure included lethargy, persistent disturbances in respiratory pattern, decreases in body weight and food and water intake, lung congestion, and damage to the corneal surface of the eyes.[Bingham, E.Cohrssen, B.Powell, C.H.Patty's Toxicology Volumes 1-9 5th ed. John Wiley & Sons. New York, N.Y. (2001)., p. 7:747]/LABORATORY ANIMALS: Acute Exposure/ In rabbits, irrigation of the eye 20 to 30 sec after instillation reduced the response, but corneal opacity and congestion of the iris with no pupillary light reaction were still noted.[Bingham, E./LABORATORY ANIMALS: Acute Exposure/ A single dermal application of 2000 mg/kg to rabbits killed all animals within 24 hr. No deaths occurred following a dermal application of 200 mg/kg.[Bingham, E./LABORATORY ANIMALS: Acute Exposure/ The oral LD50 in rats was 255 mg/kg and there were clinical signs of hypertonia, general distress, and stomach irritation.[Bingham, E.For more Non-Human Toxicity Excerpts (Complete) data for METHANESULFONYL CHLORIDE (6 total), please visit the HSDB record page.
