Is MgO Powder Hazardous for Lab Use?

[hokhani]

Dear all,
I got 20 grams of Mgo powder to be milled (to obtain Nano-powder). The person in charge of the lab said, being explosive (or something else), Mgo is a dangerous material to work with. Is it true? (since I have not found this anywhere else and some friends said it is not the case)
