SECTION 4: First aid measures
Description of necessary first-aid measures
Fresh air, rest.
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. Rest.
Most important symptoms/effects, acute and delayed
Inhalation will cause irritation and possibly nausea, vomiting, headache, and loss of consciousness. Contact with eyes causes burns. Skin contact may be irritating. (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
If material on fire or involved in fire: Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Solid streams of water may spread fire. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use foam, dry chemical, or carbon dioxide.
Specific hazards arising from the chemical
Behavior in Fire: Vapors are heavier than air and may travel considerable distance to a source of ignition and flash back. Fires are difficult to control due to ease of reignition. (USCG, 1999)
Special protective actions for fire-fighters
Use foam, powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.
Methods and materials for containment and cleaning up
Contaminated wastewaters containing butyraldehyde are produced during the MFR of poly(vinyl butyral) and poly(vinyl formal ethylal). On tha basis of lab tests, a scheme for treating wastewater is recommended. After neutralization with sodium hydroxide or calcium oxide, the organic fraction is distilled from the wastewater and incinerated.
SECTION 7: Handling and storage
Precautions for safe handling
NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Fireproof. Separated from incompatible materials. See Chemical Dangers. Cool. Keep in the dark. Store in an area without drain or sewer access.On contact with air butyraldehyde is oxidized readily to the butyric acids. Therefore, storage under inert gas is mandatory.

Persistence and degradability
AEROBIC: Butyraldehyde, present at 100 mg/L, reached 100% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(1). Butyraldehyde had a 5-day theoretical BOD of 28% using the AFNOR T test and an inoculum from 3 polluted surface waters(2). Using a sewage inocula and standard dilution water, butyraldehyde had a 5-day theoretical BOD of 43%(3). Theoretical BODs of 43.4, 59.8, and 68% were measured after 5, 10, and 50 days, respectively, using a sewage seed(4). A 5-day theoretical BOD of 106% was reported for a sewage inocula(5). Using an electrolytic respirometer and an activated sludge inocula, theoretical BODs of 46-57% were observed after 90-135 hr of incubation(6).
Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for butyraldehyde(SRC), using a log Kow of 0.88(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 butyraldehyde is estimated as 72(SRC), using a log Kow of 0.88(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that butyraldehyde is expected to have 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.
