Selective Micro 2L500, Selectrocide 2L500

SECTION 2: Hazards identification

EMERGENCY OVERVIEW Intact product is not expected to produce any measurable exposure to ingredients. If product is damaged, avoid contact with dry ingredients. Dry ingredients may cause skin and eye burns. If product contents become wet, product may produce chlorine dioxide gas. See section 11 for hazards of chlorine dioxide gas. The product is designed to release small amounts of chlorine dioxide gas into water when the pouch is filled with water, and the product design limits both the amount of gas generated and the rate of release into solution. The product produces chlorine dioxide gas when the contents are adequately wetted. Once a Selective Micro pouch (either of the 2L500 products) is filled with water or once the envelope of the Selectrocide 1G, 5G,12G, A10, and A15 package is immersed in water, the waiting time prior to use ranges from a minimum of 6 hours to a minimum of 15 hours, as specified on the product label. The quantity of active ingredient that produces chlorine dioxide gas ranges from roughly 4 to 70 grams, and chlorine dioxide gas is not expected to be released in amounts or at a rate where significant exposures could occur in normal handling and use. If not used according to directions, some chlorine dioxide gas could be released into small, enclosed spaces in sufficient quantities to be detectable. If a chlorine-like odor is detected in such a space, leave the space and ventilate it.

Potential health effects

FROM EXPOSURE TO CHLORINE DIOXIDE GAS INHALATION: Chlorine dioxide gas is a strong respiratory irritant. High exposure may cause bronchiospasm and pulmonary edema, which may be delayed in onset. May also cause severe headache. All symptoms may be delayed and long lasting. Prolonged exposure may cause bronchitis. SKIN CONTACT: Skin irritant. Gas phase may be absorbed, causing tissue and blood cell damage. EYE CONTACT: Eye irritant. Exposure may cause visual disturbance such as seeing haloes around lights. INGESTION: Aqueous solutions of chlorine dioxide gas can be irritating and in high concentrations cause chemical burns. Not anticipated from this product. ADDITIONAL DATA: May have increased effects with exposure to chlorine, other chlorine oxides and chlorine-fluorine compounds.
