Ilmaantuvara

Ilmaantuvara is an Estonian term referring to an emergency air supply or air reserve designed to provide breathable air when the primary source is unavailable or compromised. It is used in safety-critical contexts where rapid access to breathable air can be life-saving, such as in industrial settings, firefighting, diving, aviation, and other high-risk environments.

A typical ilmaantuvara system includes a reserve of compressed air or oxygen, a regulator to control flow, and a delivery method such as an emergency mask, hood, or portable breathing apparatus. The reserve is stored under safe pressure and is designed for quick activation, either manually or automatically when an airflow failure or hazardous condition is detected. Systems may be fixed in a facility, integrated into a vehicle or vessel, or carried as portable equipment.

Operation and management emphasize reliability and readiness. Regular inspections, leak testing, and component replacement are required, along with routine drills and user training. Storage and labeling standards help ensure quick identification and safe handling of gases. Maintenance responsibilities typically reside with safety officers, equipment managers, or similar roles, with clear procedures for testing, replacement, and documentation.

Ilmaantuvara practices are governed by applicable national and European safety standards and regulations, which specify criteria for performance, testing, maintenance, and training. The concept is general across sectors, with device configurations and activation methods tailored to specific risks and operational needs.
