SECTION 10: Stability and reactivity

Reactivity

100 mg/cu m Lead (as Pb)

250 mg/cu m (as Cr(II)). Chromium(II) compounds (as Cr)

25 mg/cu m (as Cr(III)). Chromium(III) compounds (as Cr)

15 mg/cu m (as Cr(VI)). Chromic acid and chromates

NIOSH considers chromic acid and chromates to be potential occupational carcinogens. Chromic acid and chromates

Decomposes on heating. This produces toxic fumes including lead oxides. Reacts violently with many substances such as combustible substances, amines, bases and metals. This generates fire and explosion hazard.

Chemical stability

Stable under recommended storage conditions.

Possibility of hazardous reactions

LEAD CHROMATE reacts violently with ferric ferrocyanide (NTP, 1992). The mixture of sulfur and the chromate is pyrophoric, as is the case of tantalum and the chromate. Under certain conditions, combinations of dry mixtures of lead chromate pigment and azo-dyes (nitrobenzeneazo derivatives) may lead to explosions. When these materials are intimately mixed, violent reactions may result [Loss Prev. Bull., 1978, (022), 117].

Other Information

Chromates are classified as human carcinogens, but evidence for this substance is limited.Lead chromate pigments may contain appreciable quantities of water-soluble lead compounds.Toxic fumes (lead and chromium compounds) are also liberated during welding, cutting and heating of material treated with lead chromate.Depending on the degree of exposure, periodic medical examination is suggested.Do NOT take working clothes home.Lead chromate occurs in nature as the minerals crocoite, phoenicochroite.NEVER use a domestic-type vacuum cleaner to vacuum the substance, only use specialist equipment.
