Reactivity Alerts
- Highly Flammable
Air & Water Reactions
Highly flammable.
Fire Hazard
Vapors form explosive mixtures in air or in sewers. Hazardous peroxides and acids emitted when heated to decomposition. Avoid nitric acid. Unstable, avoid oxygen, heat, elevated pressures. Hazardous polymerization may occur. Avoid contact with alkaline materials such as caustic ammonia or amines, or at elevated temperatures. (EPA, 1998)
Health Hazard
Although slightly less toxic, crotonaldehyde is similar chemically and toxicologically to acrolein, which is rated as extremely toxic. Toxic concentrations for human inhalation have been reported at 12 mg/m3/10 minutes. Irritant dose to human eye is 45 ppm. As with acrolein, vapor exposures cause severe and painful eye irritation, damage to cornea, lacrimation (tearing), irritation of nasal membranes, pulmonary edema (filling of lungs with fluid) and gastrointestinal distress when ingested. (EPA, 1998)
Reactivity Profile
(E)-CROTONALDEHYDE is an aldehyde. It can react violently with strong oxidizing reagents, e.g., reaction with conc. nitric acid leads to instantaneous ignition [Andrussow, L., Chim. Ind. (Paris), 1961, 86, p. 542]. In contact with strong acids or bases it will undergo an exothermic condensation reaction. Reaction with 1,3-butadiene is particularly violent [Greenlee, K. W., Chem. Eng. News, 1948, 26, p. 1985]. Crotonaldehyde may rapidly polymerize with ethyl acetoacetate (Soriano, D.S. et al. 1988. Journal of Chemical Education 65:637.).

Firefighting
All exposed skin surfaces should be covered. Wear protective clothing including self-contained breathing apparatus, coat, pants, gloves, boots, and bands around arms, wrists, legs, and waist. Massive or advanced fires should be fought from a safe distance or protected location. Isolate area for one-half mile in all directions if tank car or truck involved in fire.
Use dry chemical, foam, or carbon dioxide; water may be ineffective but should be used to keep fire-exposed containers cool. If leak or spill has not ignited, use water spray to disperse vapors. Water spray may be used to flush spills away from exposures. (EPA, 1998)

Non-Fire Response
Remove all ignition sources and ventilate area of spill. No flares, smoking, or flames in hazard area. Do not touch spilled material; stop leak if you can do so without risk. (EPA, 1998)
Protective Clothing
For emergency situations, wear a positive pressure, pressure-demand, full facepiece self-contained breathing apparatus (SCBA) or pressure- demand supplied air respirator with escape SCBA and a fully-encapsulating, chemical resistant suit. (EPA, 1998)

First Aid
Warning: Crotonaldehyde, (E)- is an extreme eye, respiratory, and skin irritant and can cause corneal damage. Caution is advised.
Signs and Symptoms of Crotonaldehyde, (E)- Exposure: Signs and symptoms of acute exposure to crotonaldehyde, (E)- may include irritation of the eyes, skin, mucous membranes, nose, throat and upper respiratory tract. Delayed onset of pulmonary edema is possible following inhalation. Corneal damage may occur as may allergic contact dermatitis. Seizures may also be observed.
Emergency Life-Support Procedures: Acute exposure to crotonaldehyde, (E)- may require decontamination and life support for the victims. Emergency personnel should wear protective clothing appropriate to the type and degree of contami-nation. 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.
Inhalation Exposure:
1. Move victims to fresh air. Emergency personnel should avoid self-exposure to crotonaldehyde, (E)-.
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. Obtain authorization and/or further instructions from the local hospital for performance of other invasive procedures.
4. Transport to a health care facility.
Dermal/Eye Exposure:
1. Remove victims from exposure. Emergency personnel should avoid self-exposure to crotonaldehyde, (E)-.
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 thoroughly 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.
Ingestion Exposure:

2. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.
3. DO NOT induce vomiting.
4. Activated charcoal may be administered if victims are conscious and alert. Use 15 to 30 g (1/2 to 1 oz) for children, 50 to 100 g (1-3/4 to 3-1/2 oz) for adults, with 125 to 250 mL (1/2 to 1 cup) of water.
5. Promote excretion by administering a saline cathartic or sorbitol to conscious and alert victims. Children require 15 to 30 g (1/2 to 1 oz) of cathartic; 50 to 100 g (1-3/4 to 3-1/2 oz) is recommended for adults.
