Section V. Toxicological Properties
PROPIONALDEHYDE page 2/4
Use DRY chemical, carbon dioxide, or alcohol-resistant foam. Water may be ineffective to extinguish fires. Wear
adequate personal protection to prevent contact with material or its combustion products. Self contained breathing
apparatus with a full facepiece operated in a pressure demand or other positive pressure mode. Cool containing vessels
with flooding quantities of water. Fight fire from maximum distance or use unmanned hose holders or monitor nozzles.
Extremely flammable. Vapor may travel considerable distance to source of ignition and flash back, eliminate all
sources of ignition. Vapor forms explosive mixture with air. Container explosion may occur under fire conditions or
when heated. Contact with oxidizers may cause fire and/or explosion. Empty container may contain explosive or
flammable residue. Sensitive to static discharge. Forms explosive peroxides on prolonged storage. Emits toxic
fumes under fire conditions.
Routes of entry Ingestion and inhalation. Eye contact. Skin contact. Skin absorption.
Effects of Acute
Exposure
Skin
Inhalation
Ingestion
Oxides of carbon (CO, CO2).
Harmful by inhalation, in contact with skin and if swallowed. Corrosive. Target organs: eyes, skin, respiratory
system.
Eye Causes severe burns and loss of vision. May cause permanent damage. IRRITATION: EYE-RABBIT 41 mg
SEVERE
Causes severe burns.
Material is extremely destructive to tissue of the mucous membranes and upper respiratory tract. Inhalation may be
fatal as a result of spasm, inflammation and edema of the larynx and bronchi, chemical pneumonitis and pulmonary
edema. Symptoms of exposure may include burning sensation, coughing, laryngitis, dyspnea, headache, nausea, and
vomiting. High concentrations may cause narcosis and loss of consciousness.
Burns in mouth, pharynx and gastrointestinal tract. See inhalation.

If conscious, wash out mouth with water. Never give anything by mouth to an unconscious or convulsing person.
Seek immediate medical attention.
Section VII. Reactivity Data
Reaction Products
Unstable. Air sensitive. Forms explosive peroxides on contact with air. Conditions to avoid: High temperatures,
sparks, open flames and all other sources of ignition, contamination.

Carcinogenic effects: Not available. Mutagenic effects: Not available. Teratogenic effects: Not available. Toxicity of the
product to the reproductive system: Not available. To the best of our knowledge, the chemical, physical, and toxicity of
this substance has not been fully investigated.
Immediately flush eyes with copious quantities of water for at least 15 minutes holding lids apart to ensure flushing of
the entire surface. Call a physician.
Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Call a physician. Wash contaminated clothing before reusing.
Remove patient to fresh air. Administer approved oxygen supply if breathing is difficult. Administer artificial respiration
or CPR if breathing has ceased. Seek immediate medical attention.
Oxidizing materials, acids, bases, reducing materials, amines, organic acids, halogens, alcohols. Polymerizes
violently in presence of methyl methacrylate.
Forms explosive peroxides on prolonged storage. If they become concentrated, these peroxides may present an
explosion hazard.

Spill and leak
Waste disposal
Storage and Handling
Wear self-contained breathing apparatus, rubber boots and heavy rubber gloves.
Evacuate the area. Eliminate all sources of ignition and ensure that all handling equipment is electrically grounded.
Stay upwind: Keep out of low areas. Cover with an activated carbon adsorbent. Place in a suitable container and
mark for disposal. Use non-sparking tools. Transport outdoors. Ventilate area and wash spill site after material pick
up is complete. DO NOT empty into drains. DO NOT touch damaged container or spilled material. Runoff to sewer
may create fire or explosion hazard.
Burn in a chemical incinerator equipped with an after burner and scrubber. According to all applicable regulations.
Harmful to aquatic life at low concentrations. Can be dangerous if allowed to enter drinking water intakes. Do not
contaminate domestic or irrigation water supplies, lakes, streams, ponds, or rivers.
May develop pressure. Refrigerate. Store in a cool place away from heated areas, sparks, and flame. Store in a well ventilated area.
Store away from incompatible materials. Do not add any other material to the container. Do not wash down the drain. Do not breathe
gas/fumes/vapor/spray. In case of insufficient ventilation, wear suitable respiratory equipment. Keep away from direct sunlight or strong
incandescent light. Keep container tightly closed and dry. Store under nitrogen. Manipulate under an adequate fume hood. Take
precautionary measures against electrostatic discharges. Ground the container while dispensing. Ground all equipment containing
material. Use explosion proof equipment. Use non-sparking tools. Watch for accumulation in low confined areas. Empty containers may
contain a hazardous residue. Do not use pressure to dispense. Handle and open container with care. Take off immediately all
contaminated clothing. This product must be manipulated by qualified personnel. Do not get in eyes, on skin, or on clothing. Wash well
after use. In accordance with good storage and handling practices. Do not allow smoking and food consumption while handling. Never
use welding or cutting torch on or near drum (even empty) because product (even just residue) can ignite explosively.

Section X. Other Information
PROPIONALDEHYDE
page 4/4
Face shield and splash goggles. Impervious gloves, apron, coveralls, and/or other resistant protective clothing. Sufficient to protect skin. If use conditions generate
vapors or mists, wear a NIOSH-approved respirator appropriate for those emission levels. Appropriate respirators may be a full facepiece or a half mask air-purifying
cartridge respirator equipped for organic vapors/mists, a self-contained breathing apparatus in the pressure demand mode, or a supplied-air respirator. Do not wear
contact lenses. Make eye bath and emergency shower available. Ensure that eyewash station and safety shower is proximal to the work-station location.
Engineering controls Use in a chemical fume hood. Use explosion-proof ventilation equipment. Use adequate ventilation. Do not use in
unventilated spaces.
Special Precautions or
comments
Extremely flammable liquid! Corrosive! Stench. Do not breathe vapor. Avoid all contact
with the product. Avoid prolonged or repeated exposure. Use in a chemical fume hood.
Keep away from heat, sparks and flame. Use non-sparking tools. Take precautionary
measures against static discharges. Bond and ground transfer containers and equipment to
avoid static accumulation. Air sensitive. Forms explosive peroxides on prolonged storage.
Store under nitrogen. May develop pressure. Refrigerate. Open carefully. Do not allow to
evaporate to near dryness. CAUTION: This product tends to form peroxides which are
relatively unstable and decompose violently. Therefore, any peroxide forming material
should be tested to the presence of peroxides before use. No propionaldehyde should be
distilled to dryness or concentrated unless peroxides have been proven to be absent.
Handle and open container with care. Container should be opened only by a technically
qualified person.
Synergistic materials: Not available.
