Methods and materials for containment and cleaning up
Evacuate persons not wearing protective equipment from area of spill or leak until clean-up is complete. Remove all ignition sources. Use HEPA vacuum or wet method to reduce dist during clean-up. Do not dry sweep. Collect powdered material in the most convenient and safe manner and deposit in sealed containers. Ventilate area after clean-up is complete. It may be necessary to contain and dispose of this chemical as a hazardous waste. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Contact your Department of Environmental Protection or your regional office of the federal EPA for specific recommendations. If employees are required to clean-up spills, they must be properly trained and equipped. OSHA 1910.120(q) may be applicable.

Persistence and degradability
AEROBIC: A standard 5 day BOD test of melamine resulted in almost no biochemical oxygen demand(1,2). Based on the five day BOD data, the author considered melamine to be non biodegradable(2). However, pure culture studies using Pseudomonas strain A and 3 mM melamine indicate the degradation pathway of melamine involves the conversion of melamine to ammeline and eventually cyanuric acid(3).
Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for melamine(SRC), using a log Kow of -1.37(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc of melamine is estimated as 50(SRC), using a log Kow of -1.37(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that melamine is expected to have very high mobility in soil. Aromatic amines may bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(4,5), suggesting that mobility may be much lower in some soils(SRC). Adsorption of melamine to suspended clay sediment was reported from pH 1 to 6.5, with a maximum absorption of 500X10-6 mols/g at pH 4.0(6).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
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.
