Is it Dangerous

It may catch fire if large quantities space self-heated. MgS is acutely toxic as soon as swallowed or carried in call with skin and eyes leading to eye damage. That is corrosive and an extremely harmful come aquatic life. The link is hazardous as soon as it come in contact with moisture developing poisonous hydrogen sulfide gas <1, 4>.
