Zinc chromate is an odorless yellow solid. Sinks in water. (USCG, 1999)

3.40 g/cm³

316 °C

Solubility in water: none

Storage site should be as close as practical to lab in which carcinogens are to be used, so that only small quantities required for expt need to be carried. Carcinogens should be kept in only one section of cupboard, an explosion-proof refrigerator or freezer (depending on chemicophysical properties ) that bears appropriate label. An inventory should be kept, showing quantity of carcinogen & date it was acquired Facilities for dispensing should be contiguous to storage area.

Strong Oxidizing Agent

Oxidizing agents, such as ZINC CHROMATE, can react with reducing agents to generate heat and products that may be gaseous (causing pressurization of closed containers). The products may themselves be capable of further reactions (such as combustion in the air). The chemical reduction of materials in this group can be rapid or even explosive, but often requires initiation (heat, spark, catalyst, addition of a solvent). Explosive mixtures of inorganic oxidizing agents with reducing agents often persist unchanged for long periods if initiation is prevented. Such systems are typically mixtures of solids, but may involve any combination of physical states. Some inorganic oxidizing agents are salts of metals that are soluble in water; dissolution dilutes but does not nullify the oxidizing power of such materials. Organic compounds, in general, have some reducing power and can in principle react with compounds in this class. Actual reactivity varies greatly with the identity of the organic compound. Inorganic oxidizing agents can react violently with active metals, cyanides, esters, and thiocyanates.
