Type of SOP: ☐ Process ☒Hazardous Chemical ☐ Hazardous Class
Purpose
Acrylic acid is a flammable liquid that is also an irritant, and corrosive, and should be treated with care by researchers. Acrylic acid is a hazard due to peroxide initiation of polymerization. It is generally used as a monomer for radical polymerizations. This compound should be inspected prior to use for peroxide crystals that may have collected around the cap, on the inside, or on the outside of the bottle by a starch iodide test paper. Acrylic acid should be labeled as a “peroxide forming chemical”.

Personal Protective Equipment (PPE)
Respirator Protection
Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).
Respirators should be used only under any of the following circumstances:
· As a last line of defense (i.e., after engineering and administrative controls have been exhausted).
· When Permissible Exposure Limit (PEL) has exceeded or when there is a possibility that PEL will be exceeded and the material has adequate warning properties (e.g., odor or taste).
· Regulations require the use of a respirator.
· An employer requires the use of a respirator.
· There is potential for harmful exposure due to an atmospheric contaminant (in the absence of PEL)
· As PPE in the event of a chemical spill clean-up process
Lab personnel intending to use/wear a respirator mask must be trained and fit-tested by EH&S. This is a regulatory requirement.
Hand Protection
Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands.

If used in solution, or mixed with other substances, and under conditions which differ from EN 374, contact the supplier of the CE approved gloves. This recommendation is advisory only and must be evaluated by an Industrial Hygienist familiar with the specific situation of anticipated use by our customers. It should not be construed as offering an approval for any specific use scenario.
NOTE: Consult with your preferred glove manufacturer to ensure that the gloves you plan on using are compatible with Acrylic Acid.

Eye Protection
Tightly fitting safety goggles. Faceshield (8-inch minimum). Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin and Body Protection
Complete suit protecting against chemicals, Flame retardant antistatic protective clothing, the type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.
Hygiene Measures
Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.
Engineering Controls
Work with acrylic acid should be conducted in a fume hood. Sash height should be kept low to avoid escaping fumes. Use explosion proof equipment like a blast shield to protect from explosions in the case of peroxide detonation.
First Aid Procedures
If inhaled
If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician.
In case of skin contact
Take off contaminated clothing and shoes immediately. Wash off with soap and plenty of water. Consult a physician
In case of eye contact
Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician. Continue rinsing eyes during transport to hospital
If swallowed
Do NOT induce vomiting. Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.
Special Handling and Storage Requirements
Avoid contact with skin and eyes. Avoid inhalation of vapor or mist. Keep away from sources of ignition - No smoking. Take measures to prevent the build up of electrostatic charge.
Conditions for safe storage Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Hygroscopic.
Spill and Accident Procedure
Chemical Spill Dial 911
Spill – Assess the extent of danger. Help contaminated or injured persons. Evacuate the spill area. Avoid breathing vapors. If possible, confine the spill to a small area using a spill kit or absorbent material. Keep others from entering contaminated area (e.g., use caution tape, barriers, etc.).
Small (<1 L) – If you have training, you may assist in the clean-up effort. Use appropriate personal protective equipment and clean-up material for chemical spilled. Double bag spill waste in clear plastic bags, label and take to the next chemical waste pick-up.
Large (>1 L) – Dial 911 and EH&S for assistance.
Chemical Spill on Body or Clothes – Remove clothing and rinse body thoroughly in emergency shower for at least 15 minutes. Seek medical attention. Notify supervisor and EH&S immediately.
Chemical Splash Into Eyes – Immediately rinse eyeball and inner surface of eyelid with water from the emergency eyewash station for 15 minutes by forcibly holding the eye open. Seek medical attention. Notify supervisor and EH&S immediately.
Medical Emergency Dial 911
Life Threatening Emergency, After Hours, Weekends And Holidays – Dial 911 or go to the nearest emergency room. Note: All serious injuries must be reported to EH&S within 8 hours.
Non-Life Threatening Emergency – Go to the Occupational Health Facility. At all other times report to the nearest emergency room. Note: All serious injuries must be reported to EH&S at within 8 hours.
Needle stick/puncture exposure (as applicable to chemical handling procedure) – Wash the affected area with antiseptic soap and warm water for 15 minutes. For mucous membrane exposure, flush the affected area for 15 minutes using an eyewash station. Page the needle stick nurse and then enter your extension. At all other times report to the nearest emergency room. Note: All needle stick/puncture exposures must be reported to EH&S within 8 hours.
Decontamination/Waste Disposal Procedure
Drain disposal of chemicals is strictly prohibited. Empty containers of acrylic acid can still pose a significant hazard. The containers should be triple rinsed and the first rinsate (first rinse liquid) collected for disposal as hazardous waste immediately after the last amount is removed. After triple rinsing, if the container is deemed to be free of residue, the label must be crossed out or defaced and the container can be discarded into the regular trash. Recycle glass only.
NOTE: Acrylic acid should be disposed of within one year from the date of opening / within the expiration date which is usually one year. Acrylic acid container that has crossed the expiration date may form shock sensitive crystals and may act as an explosive. Dispose of all the expired acrylic acid containers by taking them to the next scheduled EH&S waste pick-up with a recharge of $100 per expired Peroxide Forming Container. Never guess the opening date on PFC containers.
NOTE: If acrylic acid containers are too old (more than 2 years from the date of opening or expiration date), do not handle such containers by yourself. Call for pick-up from the lab.
Contaminated packaging
Dispose of as unused product
General hazardous waste disposal guidelines:
Label Waste
· Affix an on-line hazardous waste tag on all waste containers using the Online Tag Program as soon as the first drop of waste is added to the container
Store Waste
· Store hazardous waste in closed containers, in secondary containment and in a designated location
· Double-bag dry waste using transparent bags
· Waste must be under the control of the person generating & disposing of it
Dispose of Waste
· Dispose of regularly generated chemical waste within 90 days
· Call EH&S for questions
· Empty Containers
o Dispose as hazardous waste if it once held extremely hazardous waste (irrespective of the container size)
o Consult waste pick-up schedule
Prepare for transport to pick-up location
§ Check on-line waste tag
§ Write date of pick-up on the waste tag
§ Use secondary containment
