SECTION 5: Fire-fighting measures
5.1 Suitable extinguishing media
Piperazine is a combustible liquid. Use dry chemical, carbon dioxide, water spray, or alcohol foam extinguishers. Piperazine may burn, but does not readily ignite. Extinguish fire using an agent suitable for type of surrounding fire. Poisonous gases including nitrogen oxides and hydrogen chloride (hydrochloride) are produced in fire. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Notify local health and fire officials and pollution control agencies. Containers may explode in fire. From a secure, explosion-proof location, use water spray to cool exposed containers. If cooling streams are ineffective (venting sound increases in volume and pitch, tank discolors, or shows any signs of deforming), withdraw immediately to a secure position. If employees are expected to fight fires, they must be trained and equipped in OSHA 1910.156.
5.2 Specific hazards arising from the chemical
Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]: Combustible material: may burn but does not ignite readily.

12.1 Toxicity
- Toxicity to fish: no data available
- 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
AEROBIC: Piperazine, present at 100 mg/L, reached 1.4% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(1). In a total organic carbon (TOC) die-away test, piperazine, at an initial concentration of 36 ppm, was degraded by greater than 51% after 28 days in 3 out of 4 artificial river water inocula containing river water microorganisms collected in both spring and autumn(2). Only 0-15% biodegradation occured after 28 days in the fourth inoculum, which contained river water microorganisms collected during the spring(2). Piperazine, at 20 ppm, was degraded by 20% in river water and 77% in sea water after 3 days using the cultivation method(3).
12.3 Bioaccumulative potential
BCF values less than 0.3 to 0.9 and less than 3.9 were measured using orange-red killifish (Oryzias latipes) which were exposed to 1 and 0.1 ppm, respectively, over an 8-week period(1). According to a classification scheme(2), these BCF values suggest the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soil
The Koc of piperazine is estimated as 3.6(SRC), using a log Kow of -1.50(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that piperazine is expected to have very high mobility in soil. Measured pKa values of 9.73 (first nitrogen) and 5.33 (second nitrogen)(4), indicate that this compound will primarily exist in cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).
12.5 Other adverse effects
no data available
