Dibasic lead metaphosphate Safety Profile
A poison by ingestion. A flammable solid. When heated to decomposition it emits toxic vapors of lead and POx.
Flammable/combustible material. May be ignited by friction, heat, sparks or flames. Some may burn rapidly with flare burning effect. Powders, dusts, shavings, borings, turnings or cuttings may explode or burn with explosive violence. Substance may be transported in a molten form at a temperature that may be above its flash point. May re-ignite after fire is extinguished.
