SECTION 5: Fire-fighting measures
5.1 Suitable extinguishing media
Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (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)

SECTION 12: Ecological information
12.1 Toxicity
- Toxicity to fish: LC50 Brachydanio rerio (Zebrafish) 0.16-0.26 mg/L/96 hr /Conditions of bioassay not specified in source examined
- Toxicity to daphnia and other aquatic invertebrates: no data available
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
12.2 Persistence and degradability
In a Warburg respirometer study using aniline-acclimated activated sludge, phenylhydrazine was found to be appreciably more resistant to biological oxidation than aniline(1). Phenylhydrazine, in the static Zahn-Wellens test, was 85% biodegraded in 9-13 days; circa 25% biodegradation of this compound was reported for other laboratories using respirometer tests(2).
12.3 Bioaccumulative potential
An estimated BCF value of 2 was calculated for phenylhydrazine(SRC), using a measured log Kow of 1.25(1) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soil
The Koc of phenylhydrazine is estimated as approximately 110(SRC), using a measured log Kow of 1.25(1) and a regression-derived equation(2). According to a recommended classification scheme(3), this estimated Koc value suggests that phenylhydrazine has high mobility in soil(SRC). The pKa of phenylhydrazine has been reported as 5.21(4), suggesting this compound exists as a cation in moist soils, and cations tend to adsorb more to soils than neutral compounds(5).
12.5 Other adverse effects
no data available
SECTION 13: Disposal considerations
13.1 Disposal methods
Product
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.
