Hydrogen Cyanide (HCN)

NIST-Traceable Hydrogen Cyanide (HCN) Calibration Gas: Critical life-safety span and bump test standards for fire service overhaul operations, hazmat response teams, and industrial hygiene monitoring. Specifically formulated to verify single-gas badges and multi-gas monitors detecting toxic combustion byproducts (the "Toxic Twins" – CO & HCN). Supplied in passivated aluminum cylinders to prevent reactive gas loss.

• Firefighter Benchmark: 10 PPM HCN Balance Nitrogen (matches OSHA PEL & NIOSH STEL thresholds) • Featured Cylinder: 34L Aluminum (SKU: 34L-HCN-10) with standard C-10 (5/8"-18 UNF) connection • On-Demand Certification: Instant NIST Certificate of Analysis (CoA) accessible directly via cylinder QR code • Hardware Requirement: Use stainless steel or PTFE-lined regulators (such as 70-SS series) or 75-DFR-SS for reactive stability

Fire Service Overhaul & The "Toxic Twins"

Modern structure fires release massive concentrations of Hydrogen Cyanide from burning synthetic polymers, foams, and treated fabrics. Operating up to 35 times more toxic than Carbon Monoxide, HCN targets cellular respiration. Post-fire overhaul monitoring requires verified electrochemical sensor calibration to confirm safe respiratory removal below dangerous thresholds.

Passivated Aluminum & Instant QR Code CoA

Hydrogen Cyanide is an aggressive reactive gas that readily binds to untreated container walls. Every cylinder is packaged in chemically passivated aluminum (34L, 58L, 116L) with standard C-10 valves to ensure concentration stability throughout shelf life. To streamline field paperwork, quality audits, and ISO compliance, the batch-specific NIST-traceable Certificate of Analysis (CoA) is accessible directly by scanning the QR code printed on the cylinder label.
