Description of necessary first-aid measures
Fresh air, rest. Refer for medical attention.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .
Most important symptoms/effects, acute and delayed
Vapors will irritate nose and throat, and may cause nausea and vomiting. Liquid causes eye irritation. (USCG, 1999)
Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Aldehydes and Related Compounds
SECTION 5: Firefighting measures
Suitable extinguishing media
A water spray may dilute to a point where combustion will not be supported. Water may be ineffective. Use alcohol foam, carbon dioxide, or dry chemical.
Specific hazards arising from the chemical
Behavior in Fire: Vapor is heavier than air and may travel considerable distance to a source of ignition and flash back. (USCG, 1999)

SECTION 10: Stability and reactivity
Reactivity
The substance can presumably form explosive peroxides. The substance may polymerize under the influence of acids, bases, amines and oxidants. This generates fire or explosion hazard. Decomposes on burning. This produces toxic gases and irritating fumes.
Chemical stability
no data available
Possibility of hazardous reactions

Persistence and degradability
AEROBIC: Propionaldehyde, present at 100 mg/L, reached 94% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(1). Laboratory tests confirm the degradability of propionaldehyde by acclimated sludge and sewage(1-5) with theoretical BODs of 38% in 5 days(2), 100% in 5 hrs(3), and 29% in 24 hrs(4). Propionaldehyde is generally degraded to propionic acid and then further degraded to carbon dioxide and water(5). Six day BOD:ThOD ratios for propionaldehyde ranged from 0.35 to 0.53 using an activated sludge inocula(5). Percentages of ThOD biodegraded after 6, 12, and 24 hrs were 14.4, 24.9, and 28.8, respectively(5).
Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for propionaldehyde(SRC), using a log Kow of 0.59(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc of propionaldehyde is estimated as 50(SRC), using a log Kow of 0.59(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that propionaldehyde is expected to have very high mobility in soil.
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
