Shipping Weight: 40lbs Dimensions: 13”x13”x15”. TRANSPORT CONSIDERATIONS Sodasorbâ absorbent is non hazardous as defined in the Hazardous Materials Transportation Act and U. S. Department of Transportation regulations contained in 49 CFR. Because there is less than 4% Sodium Hydroxide (NaOH) active ingredient in the material it is not classified as a corrosive and therefore may be transported by land, sea or air without the need for any special hazard or shipping warnings.

STORAGE & HANDLING Store Sodasorbâ absorbent in an airtight container in a clean, cool and dry environment. Extremes of temperature should be avoided as they may lead to a reduction in efficiency for any absorbent material. High temperatures may evaporate the moisture content of the absorbent. Allowing the material to freeze will cause the moisture content to expand and fragment the granules causing excessive dust. Indicator treated absorbents should also be stored away from intense light, especially ultra-violet light as this degrades the indicator dye.

Because the absorbent is alkaline and caustic in nature, it is recommended that protective clothing such as gloves, goggles and mask be used when handling loose granules in both its fresh and used state.

DISPOSAL Unused Sodasorbâ absorbent is not a federally regulated hazardous waste under Resource Conservation and Recovery Act regulations. Incineration or landfill disposal in accordance with all current local, provincial and federal regulations. Material not incinerated may be alkaline.

In the past, rebreathers were occasionally oxygen-cleaned with chemicals that react adversely with the absorbent material.  Under certain circumstances residual quantities of these cleaning solvents (eg. freon or trichloroethylene) could react with absorbent materials to form highly toxic gases such as phosgene or acetylene.  Although these chemicals are no longer used to clean human life support equipment, it is always wise to verify the safety and reactivity of any and all chemicals used on your rebreather. Material Safety Data Sheets (see below) provide comprehensive information about chemical compounds and are available from the chemical manufacturer.
