Use caution: Liquids with this reactive group classification have been known to react with the absorbent listed below. More info about absorbents, including situations to watch out for...
- Mineral-Based & Clay-Based Absorbents
As an immediate precautionary measure, isolate spill or leak area for at least 50 meters (150 feet) in all directions.
SPILL: Increase, in the downwind direction, as necessary, the isolation distance shown above.
FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)
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 it 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. (EPA, 1998)
Fully encapsulating, vapor-protective clothing should be worn for spills and leaks with no fire. ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. A vapor-suppressing foam may be used to reduce vapors. Absorb with earth, sand or other non-combustible material and transfer to containers (except for Hydrazine). Use clean, non-sparking tools to collect absorbed material.
LARGE SPILL: Dike far ahead of liquid spill for later disposal. Water spray may reduce vapor, but may not prevent ignition in closed spaces. (ERG, 2016)
Signs and Symptoms of Piperidine Exposure: Signs and symptoms of acute exposure to piperidine may include irritation and burning of skin and mucous membranes. It may cause respiratory tract, liver, gastrointestinal tract, kidney, and CNS damage. Respiratory distress, asthmatic breathing, nausea, vomiting, abdominal pain, anorexia, and diarrhea have been reported.
Emergency Life-Support Procedures: Acute exposure to piperidine may require decontamination and life support for the victims. Emergency personnel should wear protective clothing appropriate to the type and degree of contamination. Air-purifying or supplied-air respiratory equipment should also be worn, as necessary. Rescue vehicles should carry supplies such as plastic sheeting and disposable plastic bags to assist in preventing spread of contamination.
1. Move victims to fresh air. Emergency personnel should avoid self-exposure to piperidine.
2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support.
3. Obtain authorization and/or further instructions from the local hospital for performance of other invasive procedures.
4. Transport to a health care facility.
1. Remove victims from exposure. Emergency personnel should avoid self-exposure to piperidine.
2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer 100% humidified oxygen or other respiratory support.
3. Remove contaminated clothing as soon as possible.
4. If eye exposure has occurred, eyes must be flushed with lukewarm water for at least 15 minutes.
5. Wash exposed skin areas three times with soap and water.
6. Obtain authorization and/or further instructions from the local hospital for performance of other invasive procedures.
7. Transport to a health care facility.
1. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer 100% humidified oxygen or other respiratory support.
2. DO NOT induce vomiting.
3. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.
4. Immediately dilute with 4 to 8 ounces (120 to 240 ml) of water (not to exceed 15 ml/kg in a child).
5. Activated charcoal may be administered if victims are conscious and alert. Use 15 to 30 gm (1/2 to 1 oz) for children, 50 to 100 gm (1-3/4 to 3-1/2 oz) for adults, with 125 to 250 mL (1/2 to 1 cup) of water.
6. Promote excretion by administering a saline cathartic or sorbitol to conscious and alert victims. Children require 15 to 30 gm (1/2 to 1 oz) of cathartic; 50 to 100 gm (1-3/4 to 3-1/2 oz) is recommended for adults.
7. Transport to a health care facility. (EPA, 1998)
