Awas husus kudu dilaksanakeun lamun hiji maké pacemaker a, sabab médan magnét kuat bisa ngaruksak éléktronika jero pacemakers.
Ulah ngelek magnét atawa nempatkeun magnet dina jangkauan barudak atawa déwasa impaired mental. Upami magnét ditelan, langsung konsultasi ka dokter sareng / atanapi milarian perhatian médis langsung.
Magnét bumi jarang tiasa nyiptakeun percikan api ngaliwatan kontak dina penanganan, khususna upami diidinan mangaruhan babarengan. Ulah pernah nanganan magnet bumi jarang dina atmosfir ngabeledug sabab sparking bisa ngahurungkeun atmosfir éta.
bubuk langka bumi téh combustible; durukan spontan bisa lumangsung nalika bubuk geus garing. Lamun grinding, salawasna baseuh grind magnet pikeun nyegah durukan spontan tina swarf grinding. Pernah ngagiling garing. Pastikeun gaduh ventilasi nyukupan nalika grinding magnet. Ulah coba mun mesin magnet ngagunakeun parabot konvensional, sabab ieu bisa ngahasilkeun chipping na shattering. Salawasna make kacamata kaamanan.
Salawasna nyimpen bubuk taneuh jarang atawa grinding swarf dina wadahna cai-kaeusi atawa atmosfir inert hermetically disegel pikeun nyegah durukan spontan.
Salawasna miceun bubuk taneuh jarang kalayan ati-ati. Ulah risiko seuneu. Disposing magnetized magnét kudu dipigawé pikeun nyegah tatu nalika nanganan.
