5.Fire-fighting measures

5.1 Extinguishing media

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)

5.2 Specific hazards arising from the chemical

Special Hazards of Combustion Products: Irritating vapors and toxic gases, such as nitrogen oxides and carbon monoxide, may be formed when involved in fire. Behavior in Fire: May ignite spontaneously when spread on a large surface or when in air and in contact with porous materials such as soil, asbestos, wood, or cloth. (USCG, 1999)

5.3 Special protective actions for fire-fighters

Wear self-contained breathing apparatus for firefighting if necessary.

6.Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures

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

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.

Contaminated packaging

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.
