Dry chemicals for fighting magnesium or metal fires
Isolate and contain burning materials. Smother with Argon
gas or non-reactive dry chemicals. Avoid water. Do not use
Halon.
For solid dense magnet: none.
Powders from chipping, crushing, grinding, slicing etc: may
ignite spontaneously and burn intensely. Rare earth metal
powders burn vigorously in halogen or oxidizing atmospheres

spilled
Waste disposal method
Precautions to be taken in Handling and Storing
Other precautions
Fine chips and powders should be gathered up
by a damp mop or broom. Do not use a vacuum
cleaner.
Metal recycling.
Powders may ignite and burn. Store under inert
gas or vacuum. Storage in water may generate
hydrogen gas.
Use water during machining processes to control
sparking of the swarf.

Garments to protect skin from direct contact
Avoid skin injuries. If powders generated are inhaled,
train workers in safe practices for combustible powders.
Magnetised parts are strongly attracted to each other and
to steel – handle firmly to avoid injury causing impacts.
