Purpose
Sodium peroxide is a strong oxidizer that may react violently with water. When exposed to incompatible
conditions, it can cause a fire or explosion. It is a corrosive chemical that can cause burns by all exposure
routes. It may be harmful if inhaled, ingested, or absorbed through the skins. It can cause severe burns to the
tissue of the mucous membranes, upper respiratory tract, skin, and eyes with irreversible damage. Sodium
peroxide is mainly used as an oxidizing and bleaching agent. It is also used as an oxygen source for
submarines and scuba gear.

Potential Hazards/Toxicity
Sodium peroxide is a strong oxidizer with the potential to cause a fire or explosion under incompatible
conditions. It may react violently with water. It may be harmful if ingested, inhaled, or absorbed through the
skin. It may cause severe irritation to the gastrointestinal tract. Material is extremely destructive to the tissue
of the mucous membranes and upper respiratory tract. Causes skin and eye burns with severe eye damage.
Symptoms of exposure include coughing, shortness of breath, headache, vomiting and nausea.
Engineering Controls
Chemical fume hood. Adequate exhaust and capture filtration. Electrically grounded lines and equipment.
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://or.ucsf.edu/ehs/8193-DSY/version/default/part/4/data/)
Hand Protection
Handle with gloves. Nitrile gloves are recommended.
NOTE: Consult with your preferred glove manufacturer to ensure that the gloves you plan on using are
compatible with sodium peroxide.

Eye Protection
ANSI approved, tight-fitting safety glasses/goggles. Face shields are recommended.
Skin and Body Protection
Flame-resistant lab coat preferably made of anti-static material, long pants, and closed-toe shoes.
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.
Consult a physician.

In case of eye contact
Flush eyes with plenty of water for at least 15 minutes lifting upper and lower eyelids and removing contact
lenses. 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
Precautions for safe handling: Avoid contact with skin, eyes, and clothing. Avoid inhalation and ingestion.
Avoid dust formation. Provide adequate exhaust ventilation. Keep away from sources of ignition- No smoking.
Open and handle container with care.
Conditions for safe storage: Keep container tightly closed in a cool, dry, and well-ventilated area.
Incompatible with strong reducing agents, acids, sulfur, organic materials, alcohols and powdered metals. Do
not allow contact with water. Store away from flammables. Store under inert gas.
Spill and Accident Procedure
Chemical Spill Dial 9-911 from campus phone or 415-476-1414 from cell phone or 415-2068522 (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 415-2068522 (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 1-800222-1222 for further exposure information. Notify your direct supervisor and EH&S at 415-4761300 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.
