Zusammenfassung:	A safety mask construction comprises a substantially rigid face portion which is receivable over a portion of the face of a wearer and a pair of substantially rigid arm portions which extend rearwardly and inwardly from opposite sides of the face portion for engagement with the rear and upper rear portions of the head of the wearer. The arm portions are preferably hingeably attached to the face portion and biased toward inwardly hinged positions so that when the safety mask is mounted on the head of the wearer, they resiliently embrace the head to retain the face portion in proper orientation thereon.
