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 ? 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
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)
Wear self-contained breathing apparatus for firefighting if necessary.
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.
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.
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.)
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.
Fireproof. Separated from strong oxidants, acids and incompatible materials. See Chemical Dangers.Fireproof. Separated from strong oxidants, acids, incompatible materials See Chemical Dangers.

Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.
Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Wear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
Wear dust mask when handling large quantities.

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).
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).
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).

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.
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.
