SRP: Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in air, soil or water; effects on animal, aquatic and plant life; and conformance with environmental and public health regulations. If it is possible or reasonable use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination.

Offer surplus and non-recyclable solutions to a licensed disposal company. Contact a licensed professional waste disposal service to dispose of this material.

Contaminated packaging: Dispose of as unused product.

Precautions for safe handling: Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Provide appropriate exhaust ventilation at places where dust is formed. Keep away from sources of ignition - No smoking. Keep away from heat and sources of ignition. Normal measures for preventive fire protection.

Appropriate engineering controls: Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.

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 material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers.

Excerpt from ERG Guide 140 [Oxidizers]:

Immediate precautionary measure

U.S.B.M. -approved toxic dust respirator; general-purpose gloves; chemical safety goggles; full cover clothing. (USCG, 1999)

Eye/face protection: Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).

Handle with gloves.

Body Protection: Impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.

Respiratory protection: Where risk assessment shows air-purifying respirators are appropriate use a full-face particle respirator type N100 (US) or type P3 (EN 143) 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).

IDENTIFICATION AND USE: Calcium peroxide is white or yellowish powder. It is used as a stabilizer for rubber. Other uses including seed disinfectant, dentifrices, dough conditioners, antiseptic, bleaching of oils, modification of starches, high temperature oxidation. An important application of calcium peroxide is for curing the polysulfide sealants used in double glazing window units. Calcium peroxide is also used at several gold mines in Australia to increase recovery of gold and reduce the consumption of cyanide. Calcium peroxide has been identified as being used in hydraulic fracturing as a breaker. HUMAN EXPOSURE AND TOXICITY: Contact with calcium peroxide can severely irritate and may burn the skin and eyes. Exposure can irritate the eyes, nose, and throat. Prolonged exposure can damage the skin. Higher levels of calcium peroxide can irritate the lungs causing coughing and/or shortness of breath. Still higher exposures may cause a buildup of fluid in the lungs (pulmonary edema). This can cause death. ANIMAL STUDIES: Experiments with calcium peroxide revealed that the compound is not toxic to dogs treated orally. ECOTOXICITY STUDIES: New method was proposed for increasing the oxygen level in lakes using granulated calcium peroxide (CaO2) as a slow oxygen releasing compound. This compound releases oxygen (O2) in a reaction with water during 5 to 7 months. The method was tested in both laboratory and field conditions.

/OTHER TOXICITY INFORMATION/ The sediment and hypolimnion of many Finnish lakes suffer from anoxia due to increasing nutrient loading. The aim of this research was to develop a method for increasing the oxygen level using granulated calcium peroxide (CaO2) as a slow oxygen releasing compound. This compound releases oxygen (O2) in a reaction with water during 5 to 7 months. The method was tested in both laboratory and field conditions. In the field test granulated CaO2 were then spread manually from a rowing boat over the whole surface of the test pond. The granules sink onto and into the sediment. No mixing was needed. The dissolved oxygen concentration increased significantly during a laboratory experiment with a CaO2 amendment of 75 g/sq m and in a pond experiment with a CaO2 amendment of 50 g/sq m. In the pond experiment, the effect was visible for the entire 40-week experiment. In the laboratory, the abundance of aerobic bacteria increased in the sediment after CaO2 addition, while the pond experiment gave more mixed results. The organic matter content of the sediment did not change during the experiment in the control pond, but decreased from 18% to 4% in the pond with the CaO2 amendment. This was possibly due to enhanced microbial activity in the test pond. Although the results show improved oxygen concentrations and effects on the sediment organic matter following CaO2 amendment, the usability of this method in larger lakes remains to be tested.

According to the 2012 TSCA Inventory Update Reporting data, 2 reporting facilities estimate the number of persons reasonably likely to be exposed in manufacturing, processing, or use of calcium peroxide in the United States is unknown due to confidential business information (CBI) or unknown values(1).

NIOSH (NOES Survey 1981-1983) has statistically estimated that 16,652 (1,039 of these were female) were potentially exposed to calcium peroxide in the US(1). Occupational exposure to calcium peroxide may occur through inhalation and dermal contact with this compound at workplaces where calcium peroxide is produced or used(SRC).

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 peroxides/

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.
