Respirators are used to protect the wearer from breathing dangerous gases, dusts, chemicals, toxins, biological hazards or airborne diseases.
Emergency Respirator
An emergency respirator is used for evacuation or rescue in situations involving respiratory hazards. They are generally intended for short-time use of approximately 15 to 30 minutes.
Air-Purifying Respirators
This respirator allows air to pass through an air-purifying filter that removes any harmful contaminants. It purifies environmental oxygen, but does not have an independent oxygen supply.
Self-Contained Breathing Apparatus
This is the type of respirator used by fire fighters. It has a limited air supply that is generated from a tank worn on the back and attached to a face mask.
Atmosphere-Supplying Respirator
This type of respirator is used in situations where oxygen levels are low or to prevent exposure to toxic vapors.
Particulate Respirators
Health care workers wear particulate respirators to protect against airborne pathogens by filtering particles out of the air they are breathing.
