  • A self-rescuer is a device to be used in case of emergency for escape through atmosphere containing carbon monoxide

  • All personnel in underground mines need to know how to use a self-rescuing device and to be aware of its limitations


Goals of the course

Goals of the Course

  • To establish a working knowledge of the self-rescuer

  • To enable the students to use the self-rescuer in an emergency procedure


Objectives

Objectives

  • Know how to operate a self-rescuer

  • Know when the self-rescuer should be used

  • Know the limitations of the self-rescuer: time, carbon monoxide and storage

  • Explain the examination procedure

  • Demonstrate the correct procedure for donning the device


What is the self rescuer

What is the Self-Rescuer?

  • Protects the wearer from carbon monoxide

  • Small enough to be carried on your belt

  • Readily available in case of emergency

  • Used at the first indication of a fire or explosion


Diagram of a self rescuer

Basic substance contained in the self-rescuer is hopcalite

Hopcalite changes carbon monoxide, a poisonous gas, into carbon dioxide, a relatively harmless gas

W 65 protection facts

W-65 Protection Facts

  • Tests conducted by the Bureau of Mines state the W-65 provides adequate protection for 60 minutes in 1% concentration of carbon monoxide

  • You must keep the self-rescuer in place regardless of the heat generation


W 65 protection facts1

W-65 Protection Facts

  • The only purpose of the W-65 is for escape or self-rescue from an atmosphere containing carbon monoxide

  • It will not provide protection in an atmosphere in which there is not enough atmosphere to function properly (less than 16.25 percent oxygen)


W 65 protection facts2

W-65 Protection Facts

  • The self-rescuer is made of durable metal enclosed in a corrosion-resistant stainless steel case

  • It cannot be reused

  • Once the seal on the self-rescuer has been broken, it must be used immediately and then discarded

  • If it is damaged, replace it with another one

Inspection and maintenance2

Inspection and Maintenance

  • The standard 30 CFR 57.15030 states an effective inspection program must be established by the operator and include both a visual inspection and weighing of the device


Inspection and maintenance3

Inspection and Maintenance

  • A visual inspection serves to identify surface defects, such as a crushed case or broken seal

  • Weighing is necessary because it is the most reliable test in determining the serviceability of a self-rescuer


Inspection and maintenance4

Inspection and Maintenance

  • The inspection program for weighing self-rescuers shall not exceed a 90-day period and provide a record of weight for each device

  • The weight gain should not be 10 or more grams

    • A device has a crushed or deeply dented case

    • A device has dents or damage around the seal area
