MSA – W65 Self-Rescuer Respirator

The MSA W65 Self-Rescuer Respirator is a compact, one-time-use air-purifying escape device designed to protect workers from toxic carbon monoxide (CO) and other harmful gases released during underground mine fires or explosions. Engineered for fast deployment and intuitive use, the W65 Self-Rescuer activates immediately once removed from its sealed stainless steel container, delivering crucial respiratory protection in emergency escape scenarios.

Equipped with a latex-free mouthpiece and nose clip, the W65 Self-Rescuer ensures a reliable seal against contaminated air, while the adjustable head harness offers a secure fit and hands-free operation, critical when navigating hazardous environments. Its lightweight design, durable construction, and belt- or shoulder-carrying options make it easy to wear during daily operations, so it’s always within reach when seconds count.

The W65 Self-Rescuer uses a unique catalyst system combining noble metal and hopcalite to filter and neutralise carbon monoxide, extending protection for over 4 hours. A trainer version is also available for effective and economical instruction.
