This product does not represent a significant hazard to health, safety or the environment when handled and stored as advised (see Section 7). Repeated, long term inhalation of ferromanganese alloy dust in excess of exposure limits may cause adverse health effects (see Section 11). Flammable and noxious gases may be formed in contact with moisture and/or acids (see Sections 10 and 11). Ferromanganese alloy dust suspended in air may under certain conditions cause dust explosions (see Section 5).
Ferromanganese alloy, as packaged, is not combustible. When suspended in air, dust of ferromanganese alloy can be ignited, will propagate flame readily, and may generate considerable pressure and/or a mild explosion. Avoid generating sparks or ignition sources in areas of high airborne dust levels or in areas with accumulated dust. The degree of combustibility in air is dependent upon particle size, oxide coating, and quality of dispersion. The hazard increases with particle fineness. Thoroughly clean areas or equipment to be maintained prior to dust disturbing or ignition source generation activities.
