Personal Protective Equipment: Because fire may product toxic decomposition products, wear a self-contained breathing apparatus (SCBA) with a full facepiece operated in pressure-demand or positive-pressure mode. Chemically compatible gloves should also be used. Spill/Leak: If KRISTALOSE is accidentally released, sweep up the material gently to minimize the dust and place the remains in a plastic bag inside a fiber drum. Seal and label the drum with the pertinent information. The remaining traces can be washed down with water. Cleanup personnel should wear a self-contained breathing apparatus (SCBA) with a full facepiece operated in pressure-demand or positive-pressure mode. Chemically compatible gloves should also be used. Disposal must be conducted according to Federal, State and Local regulations.
