01 · Identification
What Nickel Sulfate is
Nickel Sulfate is green-yellow crystals and is odorless. Its molecular formula is NiO4S and its molecular weight is 154.76 g/mol. It boils at 103 °C, melts at 840 °C.
Under the GHS it carries the signal word Danger. It is classed as carcinogens.

Storing and handling Nickel Sulfate
Storage conditions
PRECAUTIONS FOR "CARCINOGENS": 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. /Chemical Carcinogens/

Reactivity
Gives an acidic solution when dissolved in water. Emits highly toxic fumes of metallic nickel, oxides of sulfur, and oxides of nitrogen when heated to decomposition [Lewis, 3rd ed., 1993, p. 910].
