Sodium peroxide

Excerpt from ERG Guide 144 [Oxidizers (Water-Reactive)]:

NO water. Use dry powder. In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water.

Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.

First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. 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 for medical attention .

· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.

· ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.

General First Aid:

If material on fire or involved in fire: use dry chemical, graphite, or dry earth. Use water only if flooding quantities are available. Apply water from as far a distance as possible.

Evacuation: If fire becomes uncontrollable - consider evacuation of one-half (1/2) mile radius.

In case of fire, water should be applied by the sprinkler system or by hose from a safe distance, preferably with a fog nozzle. Foam may be necessary instead if the peroxide is diluted in a low density flammable solvent. Portable extinguishers should not be used except for very small fires. Peroxides threatened by fire should be wetted from a safe distance for cooling. /Peroxides, Organic and Inorganic/

KEEP TIGHTLY CLOSED & PROTECTED FROM CONTACT WITH ORGANIC OR OXIDIZABLE SUBSTANCES.

...SHOULD...BE STORED IN FIRE-RESISTING BUILDINGS, & SEPARATED FROM FLAMMABLE MATERIALS.

PROTECT AGAINST PHYSICAL DAMAGE & MOISTURE. SEPARATE FROM COMBUSTIBLE, ORGANIC OR OTHER READILY OXIDIZABLE MATERIALS. DO NOT STORE IN AREAS SUBJECT TO MOISTURE. IMMEDIATELY REMOVE & DISPOSE OF ANY SPILLED PEROXIDE.

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT absorb in saw-dust or other combustible absorbents. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. Then store and dispose of according to local regulations.

Burning sensation. Cough. Laboured breathing. Shortness of breath. Sore throat.

Redness. Serious skin burns. Pain.

Redness. Pain. Blurred vision. Severe deep burns.

Sore throat. Abdominal pain. Nausea. Shock or collapse. Burning sensation.

...MAY CAUSE CHEMICAL BURNS OF SKIN & MUCOUS MEMBRANES, ALTHOUGH BURNS CAUSED BY HYDROGEN PEROXIDE ARE LESS SERIOUS THAN THOSE CAUSED BY SODIUM PEROXIDE.

NO PRIMARY SYSTEMIC EFFECTS WHEN INGESTED BECAUSE IT IS DECOMPOSED IN /SRP: GI TRACT/ BEFORE ABSORPTION. DECOMPOSITION MAY RELEASE LARGE VOL OF OXYGEN... LARGE DOSES PRESUMABLY PRODUCE GASTRITIS & ESOPHAGITIS.

IRRITANT AND CORROSIVE

Acute exposures to sodium peroxide via inhalation may cause respiratory irritation and difficulty in breathing.

Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary ... . Monitor for shock and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool ... . Do not attempt to neutralize because of exothermic reaction. Cover skin burns with dry, sterile dressings after decontamination ... . /Oxidizers/

Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious, has severe pulmonary edema, or is in, respiratory arrest. Early intubation, at the first sign of upper airway obstruction, may be necessary. Positive pressure ventilation techniques with a bag valve mask device may be beneficial. Monitor cardiac rhythm and treat arrhythmias as necessary ... . Start an IV with D5W /SRP: "To keep open", minimal flow rate/. Use lactated Ringer's if signs of hypovolemia are present. Watch for signs of fluid overload. Consider drug therapy for pulmonary edema ... . For hypotension with signs of hypovolemia, administer fluid cautiously. Watch for signs of fluid overload ... . Use proparacaine hydrochloride to assist eye irrigation ... . /Oxidizers/

Peroxides should be washed promptly from the skin to prevent irritation. In the case of eye contact, the eyes should be flushed immediately with large amounts of water, and medical attention should be obtained. ... Medical attention should also be obtained in case of accidental ingestion. ... /Peroxides, Organic and Inorganic/
