Type of SOP: ☐ Process ☐Hazardous Chemical ☒ Hazardous Class
Purpose
Nitrilotriacetic acid and its salts may be harmful if inhaled, ingested, or absorbed through the skin. They may cause irritation to the gastrointestinal tract, respiratory tract, skin, and eyes. They are classified by IARC as Group 2B, possibly carcinogenic to humans. Nitrilotriacetic acid and its salts are used primarily as metal ion chelating and sequestering agents. They are used as a builder in synthetic detergents, in water and textile treatments, in metal plating and cleaning, and in pulp and paper production.

Potential Hazards/Toxicity
Nitrilotriacetic acid and its salts may be harmful if inhaled, ingested, or absorbed through the skin. They may cause irritation to the gastrointestinal tract, respiratory tract, skin, and eyes. They may cause cancer. They may cause kidney damage. The toxicological properties have not been thoroughly investigated.
Engineering Controls
Work with this chemical in a certified ducted fume hood. Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower.
Personal Protective Equipment (PPE)
Respirator Protection
If lab personnel would like to use respirator on a voluntary basis, they must be trained and fit-tested by EH&S. This is a regulatory requirement. (http://www.ehs.ucsf.edu/respiratory-protection-program)
Hand Protection
Handle with nitrile or chloroprene 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.
NOTE: Consult with your preferred glove manufacturer to ensure that the gloves you plan on using are compatible with nitrilotriacetic acid and its salts.

Eye Protection
ANSI approved safety glasses or goggles.
Skin and Body Protection
Lab coats should be worn. These laboratory coats must be appropriately sized for the individual and be buttoned to their full length. Laboratory coat sleeves must be of a sufficient length to prevent skin exposure while wearing gloves. Full length pants and close-toed shoes must be worn at all times by all individuals that are occupying the laboratory area. The area of skin between the shoe and ankle should not be exposed.
Hygiene Measures
Avoid contact with skin, eyes and clothing. Wash hands before breaks and immediately after handling the product.
First Aid Procedures
If inhaled
Move person into fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Consult a physician.
In case of skin contact
Wash off with soap and plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Consult a physician.
In case of eye contact
Flush with plenty of water for at least 15 minutes lifting upper and lower eyelids and removing contact lenses. Consult a physician.
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
Precautions for safe handling: Avoid contact with skin and eyes. Avoid inhalation and ingestion. Avoid dust formation. Ensure normal measures for preventative fire protection.
Conditions for safe storage: Store in secondary containment with carcinogen label on the primary container, secondary containment and the storage location. Keep containers tightly closed in a dry, cool, and well-ventilated place. Avoid strong oxidizing agents.
Spill and Accident Procedure
Chemical Spill Dial 9-911 from campus phone or 415-476-1414 from cell phone or 415-206-8522 (SFGH only)
Spill – Assess the extent of danger. Assist 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 9-911 from campus phone or 415-476-1414 from cell phone or 415-206-8522 (SFGH only) for assistance.
Chemical Spill on Body or Clothes – Remove clothing and rinse body thoroughly in emergency shower for at least 15 minutes. If discomfort persists, proceed to the Emergency Department. If no further discomfort is experienced, have the SDS ready and contact Poison Control Hotline at 1-800-222-1222 for further exposure information. Notify your direct supervisor and EH&S at 415-476-1300 during work hours, or 9-911 during non-working hours and weekends.
Chemical Splash Into Eyes – Immediately rinse eyeball and inner surface of eyelid with water for 15 minutes by forcibly holding the eye open. If discomfort persists, proceed to the Emergency Department. If no further discomfort is experienced, have the SDS ready and contact Poison Control Hotline at 1-800-222-1222 for further exposure information. Notify your direct supervisor and EH&S at 415-476-1300 during work hours, or 9-911 during non-working hours and weekends.
Medical Emergency Dial 9-911 (campus phone) or 476-6911 (cell phone)
Note: All serious injuries must be reported to EH&S at 415-476-1300 within 8 hours.
Non-Life Threatening Emergency– Go to Occupational Health Programs (OHP) Clinic, 415-885-7580, 2330 Post Street, Suite 460 Hours of Operation for Appointments: Monday - Friday 7:30 a.m. - 4:00 p.m. (except Holidays).
Note: All serious injuries must be reported to EH&S at 415-476-1300 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 by dialing 415-353-7842 (STIC).
Decontamination/Waste Disposal Procedure
Clean contaminated surfaces with soap and water and paper towels. Dispose of the paper towels as hazardous waste.
