At the same time, the system reliably removes used air and continuously reduces CO\u2082 levels within the space. <\/p>\n<p data-start=\"1313\" data-end=\"1647\">Under normal conditions, the system operates with fresh air intake. In emergency situations, it can be quickly and easily switched to <strong data-start=\"1426\" data-end=\"1446\">gas filter mode<\/strong>. This is achieved by disconnecting the flexible hoses, enabling filtered air supply in the event of chemical, biological, or other hazardous contamination.  <\/p>\n<h3 data-start=\"1654\" data-end=\"1692\">Standards, Certification, and Type Approval<\/h3>\n<p data-start=\"1693\" data-end=\"1930\">All VA-40 ventilation systems supplied by BSSD are manufactured in accordance with the regulations of the <strong data-start=\"1774\" data-end=\"1819\">Federal Office for Civil Protection (BABS) <\/strong>and are type-tested by the <strong data-start=\"1849\" data-end=\"1916\">Spiez Laboratory of the Swiss Federal Department of Defence (VBS).<\/strong><\/p>\n<p data-start=\"1932\" data-end=\"1967\"><strong data-start=\"1932\" data-end=\"1967\">Approvals<\/strong> (depending on manufacturer): BZS T 87-003, BZS TE 98-005<\/p>\n<p data-start=\"2004\" data-end=\"2165\">Approval depends on the specific configuration and manufacturer.
