5.Fire-fighting measures

5.1 Extinguishing media

Suitable extinguishing media

This chemical is a flammable liquid. Small fires: dry chemical, carbon dioxide, water spray, or alcohol foam. Large fires: water spray, fog, or alcohol foam. Move container from fire area if you can do so without risk. Do not get water inside container. Cool containers that are exposed to flames with water from the side until well after fire is out. Withdraw immediately in case of rising sound from venting safety device or any discoloration of tank due to fire. Keep unnecessary people away; isolate hazard area and deny entry. Stay upwind; keep out of low areas. Wear self-contained (positive pressure if available) breathing apparatus and full protective clothing. Isolate for ½ mile in all directions if tank car or truck is involved in fire. Poisonous gases including nitrogen oxides are produced in fire. Vapors are heavier than air and will collect in low areas. Vapors may travel long distances to ignition sources and flashback. Vapors in confined areas may explode when exposed to fire. Containers may explode in fire. Storage containers and parts of containers may rocket great distances, in many directions. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Notify local health and fire officials and pollution control agencies. 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

Piperidine evolves explosive concentrations of vapor at normal room temperatures. When heated to decomposition, it emits highly toxic fumes of nitrogen oxides. Dangerous, when exposed to heat, flame, or oxidizers. Avoid 1-Perchlorylpiperidine and oxidizing materials. Piperidine is a reactive compound and forms complexes with the salts of heavy metals. It evolves explosive concentrations of vapor at normal room temperatures. Keep away from igniting sources and heat. (EPA, 1998)

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: self-contained breathing apparatus. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

6.3 Methods and materials for containment and cleaning up

Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. (Extra personal protection: self-contained breathing apparatus.)

7.Handling and storage

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: LC50 Pimephales promelas (fathead minnow) 129.594 mg/L /96 hr. /Conditions of bioassay not specified
  • Toxicity to daphnia and other aquatic invertebrates: LC50 Daphnia magna /water flea/ 8.234 mg/L /48 hr. /Conditions of bioassay not specified
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Piperidine, present at 100 mg/L, reached 66.9 % of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(1). Piperidine is readily biodegradable in screening tests using mixed soil and sewage(2) or sewage(3) inocula. Greater than 30% BOD theoretical in 2 weeks was observed with the mixed inoculum BOD test(2). There is some evidence from pure culture studies that suggests that under certain situations microorganisms may form N-nitrosopiperidine(4); however, other pure culture studies suggest that piperidine is not nitrosated(5).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for piperidine(SRC), using a log Kow of 0.84(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

The Koc of piperidine is estimated as 68(SRC), using a log Kow of 0.84(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that piperidine is expected to have high mobility in soil. The pKa of piperidine is 11.28(3), indicating that this compound will primarily exist in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).

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.
