Hazards and Protection.
Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from strong acids. Flammables-area.
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in a well ventilated area. Ground and bond containers when transferring material. Do not get in eyes, on skin, or on clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Avoid contact with heat, sparks and flame. Do not ingest or inhale. Discard contaminated shoes. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Remove all sources of ignition.
Stable under normal temperatures and pressures.

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Combustion generates toxic fumes. Can release vapors that form explosive mixtures at temperatures above the flashpoint. To extinguish fire use water fog, dry chemical, carbon dioxide or alcohol type foam.
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.
Fire will produce irritating, corrosive and/or toxic gases.
Repeated inhalation may cause chronic bronchitis. Prolonged or repeated contact may cause skin necrosis and/or ulceration of the skin. May cause chronic cough.
Harmful if swallowed. Causes gastrointestinal tract burns. Can cause nervous system damage. May cause tremors and convulsions.
May cause severe irritation of the respiratory tract with sore throat, coughing, shortness of breath and delayed lung edema. Causes chemical burns to the respiratory tract.
Harmful if absorbed through the skin. Penetration may continue for several days. Causes skin irritation and possible severe skin irritation especially if the skin is wet or moist.
Causes eye irritation. Contact with liquid or vapor causes severe burns and possible irreversible eye damage. Eye damage may be delayed. May cause blindness.
Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Get medical aid immediately. Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen.
Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed. Extensive irrigation is required (at least 30 minutes). SPEEDY ACTION IS CRITICAL!
