SECTION 5: Firefighting measures
Suitable extinguishing media
Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: SMALL FIRE: Dry chemical, CO2 or water spray. LARGE FIRE: Dry chemical, CO2, alcohol-resistant foam or water spray. Move containers from fire area if you can do it without risk. Dike fire-control water for later disposal; do not scatter the material. FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2016)
Specific hazards arising from the chemical
Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. For electric vehicles or equipment, ERG Guide 147 (lithium ion batteries) or ERG Guide 138 (sodium batteries) should also be consulted. (ERG, 2016)
Special protective actions for fire-fighters
Wear self-contained breathing apparatus for firefighting if necessary.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.
Environmental precautions
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
Methods and materials for containment and cleaning up
Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.
SECTION 7: Handling and storage
Precautions for safe handling
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Keep in cool place. Keep contents under ... (appropriate liquid to be specified by the manufacturer). Keep under ... (inert gas to be specified by the manufacturer). Keep container tightly closed. Keep container dry. Keep container in well-ventilated place. Do not keep the container sealed.

Appropriate engineering controls
Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Individual protection measures, such as personal protective equipment (PPE)
Wear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.

SECTION 9: Physical and chemical properties and safety characteristics
-
Physical state：
Technical cyhexatin is a nearly odorless white crystalline powder that has no true melting point but degrades to bis(tricyclohexyl)tin oxide at 121 to 131°C which decomposes at 228°C; a melting point of 195-198°C is also reported. Very insoluble in water (less than 1 mg/L at 25°C), but wettable by water. Soluble in some organic solvents (acetone 1.3 g/L; xylenes 3.6 g/L; carbon tetrachloride 28 g/L; dichloromethane 34 g/L). Used as an acaricide (an agent to kill plant-feeding mites) in almonds, walnuts, hops and some fruits.

SECTION 10: Stability and reactivity
Reactivity
80 mg/cu m [25 mg/cu m (as Sn)]
Chemical stability
Stable to 100 deg c in aqueous suspensions from slightly acid (ph 6) to alkaline; degraded by u.v. light.
Possibility of hazardous reactions
CYHEXATIN is incompatible with strong oxidizing agents. Soluble in some organic solvents (acetone 1.3 g/L; xylenes 3.6 g/L; carbon tetrachloride 28 g/L; dichloromethane 34 g/L). Stable in aqueous suspensions in neutral and alkaline pH (above pH 6), but reacts exothermically as a base in the presence of strong acids to form salts. Converts to dicyclohexyltin oxide and further to cyclohexylstannoic acid upon exposure to ultraviolet radiation.
Conditions to avoid
no data available
Incompatible materials
Strong oxidizers, ultraviolet light.
Hazardous decomposition products
When heated to decomp ... emits acrid smoke and irritating fumes.

Persistence and degradability
Studies with plictran indicated degradation proceeded to inorganic tin compounds with stannic acid as the main product.
Bioaccumulative potential
An experimental BCF of 5 has been determined for tricyclohexyltin hydroxide in static ecosystems tests using an unreported species of fish(1). The BCFs in crucian carp obtained in a 7-day experiment were 50(muscle), 50 (vertebra); 112 (liver); and 31 (kidney)(2). According to a classification scheme(3), these BCF values suggest the potential for bioconcentration in aquatic organisms is moderate(SRC).
Mobility in soil
The Koc for tricyclohexyltin hydroxide is >4365(1). According to a classification scheme(2), this Koc value suggests that tricyclohexyltin hydroxide is expected to be immobile in soil. Tricyclohexyltin hydroxide appears to be strongly bound to soil based on a field experiment in which 90% of the cyclohexyltin compounds found in the soil of an orchard sprayed with a tricyclohexyltin hydroxide formulation was present in the uppermost 1 cm layer of the soil(3).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
