SECTION 4: First aid measures
Description of necessary first-aid measures
Fresh air, rest. Half-upright position. Refer for medical attention.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.
Most important symptoms/effects, acute and delayed
May burn skin or eyes upon short contact. INHALATION: eye and nasal irritation and lacrimation. INGESTION: may cause severe damage to the gastrointestinal tract. (USCG, 1999)
Exposure Routes: inhalation, skin absorption, ingestion, skin and/or eye contact Symptoms: Irritation eyes, skin, respiratory system; eye, skin burns; skin sensitization Target Organs: Eyes, skin, respiratory system (NIOSH, 2016)
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. Organic acids and related compounds
SECTION 5: Firefighting measures
Suitable extinguishing media
Use dry chemical, carbon dioxide, or alcohol foam extinguishers. Vapors are heavier than air and will collect in low areas. Vapors may travel long distances to ignition sources and flashback. Vapors in confined areas may explode when exposed to fire. Storage containers and parts of containers may rocket great distances, in many directions. In advanced or massive fires, fire fighting should be done from a safe distance or from a protected location. If a leak or spill has not ignited, use water spray to disperse the vapors. Water spray may be used to flush spills away from exposures and to dilute spills to nonflammable mixtures. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Notify local health and fire officials and pollution control agencies. From a secure, explosion-proof location, use water spray to cool exposed containers. If cooling streams are ineffective (venting sound increases in volume and pitch, tank discolors or shows any signs of deforming), withdraw immediately to a secure position.
Specific hazards arising from the chemical
Special Hazards of Combustion Products: Toxic vapors are generated when heated Behavior in Fire: May polymerize and explode (USCG, 1999)
Excerpt from ERG Guide 132P [Flammable Liquids - Corrosive]: Flammable/combustible material. May be 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, alcohol-resistant foam, powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Ventilation. 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.
Environmental precautions
Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Ventilation. 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.
Methods and materials for containment and cleaning up
SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.
SECTION 7: Handling and storage
Precautions for safe handling
NO open flames, NO sparks and NO smoking. Above 48°C use a closed system, ventilation and explosion-proof electrical equipment. Vapours will be uninhibited and may polymerize in exhaust or ventilation facilities with risk of breakdown. 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 strong oxidants, strong bases, strong acids and food and feedstuffs. Keep in the dark. Store only if stabilized. Store in an area without drain or sewer access. Storage conditions may vary according to the type of inhibitor used. Refer to the manufacturer's instructions for proper storage conditions. See Notes.Acrylic acid should be stored in a detached, cool, well-ventilated, non-combustible place, and its containers should be protected against physical damage. Acrylic acid can be stored only in vessels lined with glass, stainless steel, aluminum, or polyethylene. In order to inhibit polymerization during transport and storage, 200 ppm MeHQ (the monomethyl ether of hydroquinone) is commonly added to acrylic acid by the manufacturer. The presence of oxygen is required for the inhibitor to be effective. A major concern during the storage of acrylic acid is the avoidance of elevated temperatures as well as freezing, since both can lead to a failure of the inhibitor system. Ideally acrylic acid should be stored within a temperature range of 15 to 25 deg C.

SECTION 10: Stability and reactivity
Reactivity
The substance readily polymerizes due to heating, under the influence of light, oxygen, oxidizing agents such as peroxides or other activators (acid, iron salts). This generates fire or explosion hazard. Decomposes on heating. This produces toxic fumes. The substance is a medium strong acid. Reacts violently with strong bases and amines. Attacks many metals including nickel and copper.
Reacts violently with oxidants oxidants. This generates fire and explosion hazard.
Chemical stability
Acrylic acid and methacrylic acid readily polymerize in the presence of light, heat and oxygen, and also under the action of oxidizing agents such as peroxides.
Possibility of hazardous reactions
Flammable liquid. ... A fire hazard when exposed to heat or flame.Vapours are uninhibited and may polymerize in vents or flame arresters, causing blockage.,Dust explosion possible if in powder or granular form, mixed with air. If dry, it can be charged electrostatically by swirling, pneumatic transport, pouring, etc.ACRYLIC ACID may polymerize violently especially when the frozen acid is partially thawed (freezing point 12°C or 53°F). Frozen acid should be melted at room temperature and the process should be well stirred. Do not use heat during the melting process [Kirk-Othmer, 3rd ed., Vol. 1, 1978, p. 330]. Corrodes iron and steel and polymerization may occur on contact with iron salts. The uninhibited acid polymerizes exothermically at ambient temperature and explodes if confined. The inhibitor (usually hydroquinone) greatly reduces the tendency to polymerize. Explosive polymerization can also occur with strong bases, amines, ammonia, oleum, chlorosulfonic acid, and peroxides. Mixing with 2-aminoethanol, 28% ammonium hydroxide, ethylenediamine or ethyleneimine in a closed container causes an increase in temperature and pressure. Can react violently with oxidizing reagents and strong bases [Bretherick, 5th ed., 1995, p. 419].
Conditions to avoid
no data available
Incompatible materials
Violent reaction with strong oxidizers. Incompatible with sulfuric acid, caustics, ammonia, amines, isocyanates, alkylene oxides, epichlorohydrin, toluene diamine, oleum, pyridine, methyl pyridine, n-methyl pyrrolidone, 2-methyl-6-ether aniline, aniline, ethylene diamine, ethyleneimine, and 2-aminoethanol. Severely corrodes carbon steel and iron; attacks other metals. May accumulate static electrical charges and may cause ignition of its vapors.
Hazardous decomposition products
Acrylic acid rapidly decomposes in the atmosphere by photochemical attack on the double bond.

Reproductive toxicity
No information is available on the reproductive or developmental effects of acrylic acid in humans. Decreased body weight gain and decreased fertility were reported in one study of rats exposed to acrylic acid by ingestion, although the decrease in fertility was not statistically significant compared with the control. Embryotoxic and teratogenic effects (birth defects) were observed in rats injected with acrylic acid.
STOT-single exposure
The substance is corrosive to the eyes and skin. Corrosive on ingestion. The vapour is severely irritating to the eyes and respiratory tract.
STOT-repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the upper respiratory tract and lungs. This may result in reduced lung function and hyperreactivity of the airways. See Notes.
Aspiration hazard
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C , on spraying or dispersing much faster.
SECTION 12: Ecological information
Toxicity
- Toxicity to fish: LC50; Species: Brachydanio rerio (Zebra fish); Conditions: semi-static, open system, measured concentration; Concentration: 222 mg/L/96 hr
- Toxicity to daphnia and other aquatic invertebrates: EC50 - 95 mg/L - 48 h.
- Toxicity to algae: EC50 - 0.04 mg/L - 72 h.
- Toxicity to microorganisms: no data available
Persistence and degradability
AEROBIC: Acrylic acid, present at 100 mg/L, reached 68% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(1). The BOD5/COD ratio for acrylic acid was determined to be 0.22, which is indicative of significant potential for biodegradability(2). A microbial degradation study of acrylic acid in soil indicated that acrylic acid, formed from hydrolysis of acrylamide added to soil, was totally degraded within 15 days of its formation(3).
Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for acrylic acid(SRC), using a log Kow of 0.35(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
Koc values for acrylic acid have been reported as 6 in Washington clay/loam (29% sand, 42% silt, 29% clay, 3.39% organic carbon, pH 6.0), 9 in Canfield loam (45% sand, 42% silt, 13% clay, 4.58% organic carbon, pH 6.1), 29 in Ellsworth loam (35% sand, 40% silt, 25% clay, 1.42% organic carbon, pH 7.2), 137 in Tyner loamy sand (79% sand, 14% silt, 7% clay, 0.46% organic carbon, pH 5.2), and 33 in sandy loam sediment (53% sand, 28% silt, 19% clay, 1.23% organic carbon, pH 7.5)(1) According to a classification scheme(2), these Koc values suggest that acrylic acid is expected to have very high to high mobility in soil. The pKa of acrylic acid is 4.26(3), indicating that this compound will exist almost entirely in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).
Other adverse effects
no data available
