5.2 Specific hazards arising from the chemical
no data available
5.3 Special protective actions for fire-fighters

SECTION 6: Accidental release measures
6.1 Personal precautions, protective equipment and emergency procedures
Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.
6.2 Environmental precautions
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
6.3 Methods and materials for containment and cleaning up
Decontamination is most successful when the material can be recycled for use in a nuclear facility since the need to prove releasability (cleanliness) is eliminated. Nevertheless, cleaning material for unrestricted release is also possible in some cases. It may also be possible to decontaminate an item enough to change its classification from TRU/transuranic/ waste to LLW /low-level waste/, thereby allowing immediate disposal of the item, while a relatively small quantity of decontamination waste is stored as TRU waste. Electropolishing to remove the thinnest metal surface has been very effective and produces a relatively small waste volume, especially when one of the wetted sponge units is used rather than an emersion tank. Surface scabbling has been used in decontamination of concrete, and various abrasive blasting methods have also been effective. Strippable and self-stripping coatings may be used to decontaminate surfaces, even though the primary application of strippable coatings has been in preventing contamination of surfaces.

12.3 Bioaccumulative potential
Fish may take up americium, but little builds up in the fleshy tissue(1). BCF values for americium-241 measured for various fish at the Department of Energy's Savannah River Site, SC were reported in 1996 as follows: largemouth bass (muscle), 2,500; bullhead catfish (bone), 4,200. In a study performed at a nuclear waste pond at Hanford, WA, the maximum concentration of actinides, including americium-241, that would accumulate in the whole fish and fish fillet were measured. In this waste pond, the sediment concentration of americium-241 was about 5.5 Bq/g, approximately 3 orders of magnitude above background levels. Both the bluegill and largemouth bass were studied. The concentration of americium-241 in the water was about 7 uBq/mL. The results from the Hanford study indicate that both short- and long-term uptakes of americium were low; that uptake was similar for short-term (5 days) and long-term (430 days) experiments; and that direct sediment-to-fish transfer was the primary route for americium uptake. In both species of fish, there were only a few cases where fillet concentrations were >10 times those in controls. The maximum concentration of americium-241 obtained in bass and bluegill were 1.1 and 1.0 mBq/mL dry weight in fillet and 2.5 and 74 mBq/mL in whole fish(1).
12.4 Mobility in soil
Americium has been shown to be largely associated with the high molecular weight organic factions of dissolved organic matter in the soil solution of two grassland soils, a soddy podzolic soil and a peat soil, in the vicinity of the nuclear reactor at Chernobyl, Ukraine. The distribution coefficients for americium-241 in these soils were (soil type (depth), Kd in mL/g): soddy podzolic-sod layer (0 to 2 cm), 1,220; soddy podzolic-mineral layer (2 to 5 cm), 810; peat (0 to 2 cm), 2,760; and peat (2 to 5 cm), 4,550(1). While it was similarly shown that the concentration of americium-241 was 2 to 3 times higher in organic matter than in whole sediment from Lake Michigan, organic matter was a very minor constituent of the sediment (<0.5%), so organic matter was associated with a smaller percentage of americium despite its higher concentration. The bulk of the americium-241 in Lake Michigan was found in the hydrous oxides fraction of both the sediment core samples and the suspended particulate matter(1).
12.5 Other adverse effects

SECTION 13: Disposal considerations
13.1 Disposal methods
Product
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Contaminated packaging
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
