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
In case of fire in the surroundings, use appropriate extinguishing media.

Chemical stability
Stable at temp up to 60 deg c, in neutral & acidic media
Possibility of hazardous reactions
RONNEL is non-flammable and non-combustible. Decomposes with heating to evolve toxic and corrosive vapors (hydrogen chloride, phosphorus oxides, sulfur oxides). Incompatible with strong oxidizing agents.
Conditions to avoid
no data available
Incompatible materials
Strong oxidizers.
Hazardous decomposition products
When heated to decomposition it emits very toxic fumes of /hydrogen chloride/, oxides of phosphorus and oxides of sulfur.

SECTION 12: Ecological information
Toxicity
- Toxicity to fish: LC50 Lepomis macrochirus (bluegill) 1300 ug/l (95% confidence limit 1180-1430 ug/l), wt 1.0 g. Static bioassay without aeration, pH 7.2-7.5, water hardness 40-50 mg/l as calcium carbonate and alkalinity of 30-35 mg/l. /Technical material, 95%)
- Toxicity to daphnia and other aquatic invertebrates: no data available
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
Persistence and degradability
Strains of microorganisms, Bacillus subtilis isolated from polluted water samples, completely degraded 8 ppm ronnel solution in less than 6 days(1). The mean of second order rate constant for microbial transformation of ronnel in natural river and pond waters was estimated to be 1.9X10-11 l/organisms-hr(2). Assuming that the concentration of microorganisms to be constant at 1.8X10+8 organisms/l(2), the half-life for the pseudo first order biotransformation rate can be estimated as 8.4 days(SRC). In a natural water sample, the biodegradation of ronnel showed a lag period of greater than 3 days. When a natural water sample was amended with inorganic nutrients (nitrogen, phosphorus, and traces of iron and magnesium), the lag period decreased by about 45% and of biodegradation half-life decreased to about half the value of an unamended solution(2).
Bioaccumulative potential
In a continuous flow-through system, the equilibrium bioconcentration factor (BCF) for ronnel in the guppy (Poecilia reticulata) was 43650 on the lipid weight basis(2). Based on a regression equation(1) and a log Kow value of 4.98(3), a whole-body BCF value of 3588 is estimated for ronnel(SRC). Therefore, bioconcentration of ronnel in aquatic organisms may be an important fate process(4,SRC).
Mobility in soil
Based on regression equations(3), log Koc values of 3.64 and 4.09 are estimated assuming a water solubility of 1 mg/l at 20 deg C(2) and a log Kow value of 4.98(1), respectively(SRC). These log Koc values indicate that ronnel would have a very low mobility in soil(4). Conversely, ronnel would remain strongly adsorbed to sediment and suspended solids in water(SRC). In sediment from Mississippi River that contained 1.4% organic carbon, 96% of ronnel was found in the sediment-sorbed phase(5).
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.
