Application
• Chemical oxygen self-rescuer supply the wearer with oxygen which is generated from a chemical (KO2). In
a closed circuit the exhalation air of the user is regenerated and enriched with oxygen. The carbon dioxide
and humidity of the exhalation air react with the chemical, whereby carbon dioxide is removed and
oxygen is generated.
• They are respiratory protective device for self-rescue which functions independently of the ambient
atmosphere, protects the wearer during gas outbursts, fires and after explosions against toxic gases and
oxygen deficiency while escaping or waiting for rescue.
Features
• Anti-fog goggles protects the user against dust, irritating vapors produced in emergency.
• Moisture indicator to check and determine the good condition of equipment.
• Anti-static and shock-resistant.
• Metallic cover protects the bottom of self-rescuer.
• Ergonomically system with waist, with stainless steel buckles, by mean of belt to regulate as the user want.
