Acrolein

CAS RN: 107-02-8

Other Preventive Measures

ACCIDENTAL RELEASE MEASURES: Personal precautions, protective equipment and emergency procedures: Wear respiratory protection. Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Remove all sources of ignition. Evacuate personnel to safe areas. Beware of vapors accumulating to form explosive concentrations. Vapors can accumulate in low areas. Environmental precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided.
Precautions for safe handling: Avoid contact with skin and eyes. Avoid inhalation of vapor or mist. Use explosion-proof equipment. Keep away from sources of ignition - No smoking. Take measures to prevent the build up of electrostatic charge.
Appropriate engineering controls: Avoid contact with skin, eyes and clothing. Wash hands before breaks and immediately after handling the product.
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.
Employees should wash immediately with soap when skin is wet or contaminated. Remove nonimpervious clothing immediately if wet or contaminated. Provide emergency showers and eyewash.
Persons exposed only to acrolein vapor do not pose secondary contamination risks. Persons whose clothing or skin is contaminated with liquid acrolein can secondarily contaminate others by direct contact or off-gassing vapor.
Its odor threshold of 0.16 ppm is similar to the OSHA permissible exposure limit (0.1 ppm); thus odor may provide an adequate warning of potentially hazardous concentrations.
Basic Decontamination. Victims who are able may assist with their own decontamination. Quickly remove and double-bag contaminated clothing and personal belongings. Flush exposed skin and hair with copious amounts of water. Wash with soap and rinse thoroughly with water. Use caution to avoid hypothermia when decontaminating victims, particularly children or the elderly. Use blankets or warmers after decontamination as needed. Flush exposed or irritated eyes with tepid water for 15 minutes. Remove contact lenses if easily removable without additional trauma to the eye. Continue eye irrigation during other basic care and transport. If pain or injury is evident, continue irrigation while transferring the victim ...
All tanks, processing vessels, pumps, reactors, heat exchangers, & similar equipment should be protected by adequate emergency vent-relief devices. Acrolein vapors are not inhibited & can form polymers in vent lines, valves, & flame arresters with subsequent stoppage of the vent.
In case of /acrolein/ contamination with mineral acids or alkalis, depending on the amt involved, the temp rise may be slow enough to permit control injection of a buffer solution /of acetic acid, glacial or hydroquinone, photo-grade or sodium acetate, anhydrous/. An emergency supply should be available at all times in areas where acrolein is handled. The effectiveness of stored buffer is unchanged by discoloration.
Hazardous situations are most likely to occur when it is necessary to deviate from standard operating procedures. The acrolein system should be a dedicated system & almost completely isolated, so that the possibility of contamination can only occur when temporary tie-ins are made. No hoses or lines should be used in blowing lines, washing equipment ... unless the past history of the hose is known & the hose is thoroughly cleaned.
SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
SRP: Contaminated protective clothing should be segregated in a manner such that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. The completeness of the cleaning procedures should be considered before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at the end of shift, but should remain at employee's place of work for cleaning.
Air packs or fresh air breathing masks should be available in an area where acrolein is handled. Safety showers & eye baths must be avail in the area.
Evacuation: If material leaking (not on fire), consider evacuation from downwind area based on amount of material spilled, location, and weather conditions. /Acrolein, stabilized/
Personnel protection: Avoid breathing vapors. Keep upwind. ... Avoid bodily contact with the material. ... Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water. /Acrolein, stabilized/
If material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard. Use water spray to disperse vapors and dilute standing pools of liquid. /Acrolein, stabilized/
Eating and smoking should not be permitted in areas where liquid acrolein is handled, processed, or stored.
The worker should immediately wash the skin when it becomes contaminated.
Work clothing that becomes wet should be immediately removed due to its flammability hazard (i.e., for liquids with a flash point <100 deg F).
