Certified 275N Industrial Lifejackets for Ports, Construction, Commercial Fishing & Offshore

Personnel working across commercial shipping, quaysides, cargo terminals, marine engineering, and fishing decks routinely wear heavy PPE: high-visibility parkas (EN ISO 20471), flame-retardant suits, heavy PVC oilskins, steel-toe boots, or tool belts. Upon accidental water immersion, trapped air within heavy garments counteracts natural buoyancy. A standard 150 Newton lifejacket often lacks the righting torque required to rotate an incapacitated person into a safe face-up attitude.

A 275 Newton lifejacket (certified compliant with EN ISO 12402-2) is purpose-engineered to overcome garment air-entrapment and provide immediate, commanding righting torque. Delivering actual positive buoyancy between 275 and 320 Newtons, it elevates the casualty's head significantly above chop and spray, preserving clear airways in severe conditions.

• Exceptional Self-Righting Torque: Engineered to turn an unconscious person wearing bulky winter workwear or industrial clothing within 5 seconds.
• High-Capacity 60g CO₂ Charge: Powered by heavy-duty 60-gram CO₂ gas cylinders (1/2"-20 UNF standard thread) providing instantaneous chamber inflation.
• Durable Valise Options: Available in high-abrasion Cordura® nylon, flame-retardant/antistatic (FR AST) textiles, or wipe-clean PVC outer covers resistant to oils, grease, and industrial chemicals.
• SIOEN PPE Compatibility: Mullion 275N vests are cut specifically to integrate over SIOEN hi-vis jackets and heavy foul weather gear without restricting mobility.
