Cover skin burns with dry sterile dressings after decontamination ... . /Poisons A and B/

5.Fire-fighting measures

5.1 Extinguishing media

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. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form. (ERG, 2016)

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

Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.

6.2 Environmental precautions

Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Ventilation. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

6.3 Methods and materials for containment and cleaning up

Evacuate persons not wearing protective equipment from area of spill or leak until clean-up is complete. Remove all ignition sources. Collect powdered material in the most convenient and safe manner and deposit in sealed containers. Ventilate area after clean-up is complete. It may be necessary to contain and dispose of this chemical as a hazardous waste. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Contact your Department of Environmental Protection or your regional office of the federal EPA for specific recommendations. If employees are required to clean-up spills, they must be properly trained and equipped. OSHA 1910.120(q) may be applicable.

7.Handling and storage

7.1 Precautions for safe handling

Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.

7.2 Conditions for safe storage, including any incompatibilities

Separated from strong acids, strong oxidants, acid anhydrides, metals and food and feedstuffs. Dry. Well closed.Piperazine must be stored to avoid contact with oxidizers (such as perchlorates, peroxides, permanganates, chlorates, and nitrates) since violent reactions occur. . Sources of ignition such as smoking and open flames are prohibited where piperazine is used, handled, or stored in a manner that could create a potential fire or explosion hazard. Store in tightly closed containers in a cool, well vented area away form oxidizers. Where possible, automatically transfer material from drums or other storage containers to process containers. Metal containers involving the transfer of this chemical should be grounded and bonded. Wherever this chemical is used, handled, manufactured, or stored, use explosion-proof electrical equipment and fittings.

  • 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

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.
