The term 'Kind of Mask' can refer to three different types of masks: a SKI mask, a GAS mask, and an OXYGEN mask. A SKI mask is a type of face covering that is typically made of a thick fabric and is designed to keep the wearer's face warm while skiing or engaging in other outdoor activities. A GAS mask is a device that covers the face and filters out hazardous gases and particles from the air. An OXYGEN mask is a device that delivers OXYGEN to the wearer through a tube connected to a tank of OXYGEN.
