  • 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?

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
regulations for self rescue devices

inspection and maintenance
Inspection and Maintenance
  • Before going underground examine your self-rescuer for any external damage
  • If it is damaged, replace it with another one
inspection and maintenance1
Inspection and Maintenance
  • Should the self-rescuer be damaged while underground, it may be impossible in cases of emergency to remove the respirator from the container
  • In this case, the wearer can still breathe with the filter in the container
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
