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 of concentrated vapor may irritate eyes, nose and throat. Liquid is irritating to the eyes. Prolonged contact with the skin may cause 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 if 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.
SECTION 5: Firefighting measures
Suitable extinguishing media
Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
Specific hazards arising from the chemical
Excerpt from ERG Guide 129 [Flammable Liquids (Water-Miscible / Noxious)]: HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. (ERG, 2016)
Special protective actions for fire-fighters
Use water spray, foam, powder, carbon dioxide.
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 and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.
Environmental precautions
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 and spilled liquid in sealable containers as far as possible. 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
ACCIDENTAL RELEASE MEASURES: Personal precautions, protective equipment and emergency procedures: Use personal protective equipment. 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. Methods and materials for containment and cleaning up: Contain spillage, and then collect with an electrically protected vacuum cleaner or by wet-brushing and place in container for disposal according to local regulations. Keep in suitable, closed containers for disposal.
SECTION 7: Handling and storage
Precautions for safe handling
NO open flames. Above 63°C use a closed system and ventilation. 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.

SECTION 10: Stability and reactivity
Reactivity
The substance can form explosive peroxides under special conditions. Reacts violently with aluminium, bases, iron, oxidants and phenol. This generates fire and explosion hazard.
Chemical stability
Stable under recommended storage conditions.
Possibility of hazardous reactions
Combustible liquid.A nontoxic, combustible liquid, reacts with oxidizing reagents. BENZALDEHYDE must be blanketed with an inert gas at all times since it is oxidized readily by air to benzoic acid [Kirk-Othmer, 3rd ed., Vol. 3, 1978, p. 736]. In contact with strong acids or bases it will undergo an exothermic condensation reaction [Sax, 9th ed., 1996, p. 327]. A violent reaction was observed on contact with peroxyacids (peroxyformic acid) [D'Ans, J. et al., Ber., 1915, 48, p. 1136]. An explosion occurred when pyrrolidine, benzaldehyde, and propionic acid were heated to form porphyrins.
Conditions to avoid
no data available

Persistence and degradability
AEROBIC: Benzaldehyde had a 5 day theoretical BOD of 36% using the AFNOR T test and inoculum from 3 polluted surface waters(1). Using a sewage inocula and standard dilution water, benzaldehyde had a 10-day theoretical BOD of 62%(2). Theoretical BODs of 41-70% were observed (at 500 ppm concentration) in Warburg respirometers using 3 different activated sludge seeds and 6 days of inubation(3). Theoretical BOD of 13% was observed (at 500 ppm concentration) in a Warburg respirometer using a digester sludge seed acclimated to benzene and 6 hr incubation(4). Theoretical BODs of 30-38% were observed (at 250 ppm concentration) in Warburg respirometers using activated sludge seeds acclimated to phenol, benzyl alcohol or anthranilic acid and 12 hr incubation(5). About 99% of initial benzaldehyde was removed (based upon COD) in 5 days of incubation using an activated sludge inocula that had been acclimated to benzaldehyde for 20 days(6). Five-day theoretical BODs of 77.2% and 63.5% were measured using the standard dilution method and seawater dilution method, respectively(7). Benzaldehyde, present at 100 mg/L, reached 66% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test which classified the compound as readily biodegradable(8).
Bioaccumulative potential
An estimated BCF of 4.4 was calculated in fish for benzaldehyde(SRC), using a log Kow of 1.48(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.
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of benzaldehyde can be estimated to be 11(SRC). According to a classification scheme(2), this estimated Koc value suggests that benzaldehyde 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.
