2PurposeA self-rescuer is a device to be used in case of emergency for escape through atmosphere containing carbon monoxideAll personnel in underground mines need to know how to use a self-rescuing device and to be aware of its limitations
3Goals of the CourseTo establish a working knowledge of the self-rescuerTo enable the students to use the self-rescuer in an emergency procedure
4Objectives Know how to operate a self-rescuer Know when the self-rescuer should be usedKnow the limitations of the self-rescuer: time, carbon monoxide and storageExplain the examination procedureDemonstrate the correct procedure for donning the device
5What is the Self-Rescuer? Protects the wearer from carbon monoxideSmall enough to be carried on your beltReadily available in case of emergencyUsed at the first indication of a fire or explosion
6Diagram of a Self-Rescuer Basic substance contained in the self-rescuer is hopcaliteHopcalite changes carbon monoxide, a poisonous gas, into carbon dioxide, a relatively harmless gas
7W-65 Protection FactsTests conducted by the Bureau of Mines state the W-65 provides adequate protection for 60 minutes in 1% concentration of carbon monoxideYou must keep the self-rescuer in place regardless of the heat generation
8W-65 Protection FactsThe only purpose of the W-65 is for escape or self-rescue from an atmosphere containing carbon monoxideIt will not provide protection in an atmosphere in which there is not enough atmosphere to function properly (less than percent oxygen)
9W-65 Protection FactsThe self-rescuer is made of durable metal enclosed in a corrosion-resistant stainless steel caseIt cannot be reusedOnce the seal on the self-rescuer has been broken, it must be used immediately and then discarded
10Regulations for Self-Rescue Devices 30 CFR a one hour self-rescue device approved by the Mine Safety and Health Administration shall be made available by the operator to all personnel underground
11Regulations for Self-Rescue Devices 30 CFR Must be worn at all times or carried by all persons underground except for the following:when it is hazardous to a person to wear or carry the device, it shall be located at a distance no greater than 25 feet from such personwhen a person works on or around mobile equipment, it may be placed in a readily accessible location on such equipment
12Operation of W-65 Self-Rescuer Open self-rescuer by firmly pulling lever up to break canister seal
13Operation of W-65 Self-Rescuer Pull and remove lever
14Operation of W-65 Self-Rescuer Remove cover and discard
15Operation of W-65 Self-Rescuer Remove the unit from the container by wrapping the headstrap around the wrist and pulling firmly
16Operation of W-65 Self-Rescuer Grip rubber tips of mouthpiece firmly between teeth, making an airtight seal with lips and mouthpiece
17Operation of W-65 Self-Rescuer Close nostrils with the nose clip
18Operation of W-65 Self-Rescuer Remove hat and place head strap on head.Replace hat
19Operation of W-65 Self-Rescuer Go to fresh air immediately as you breathe only through the self-rescuerA breathing resistance, similar to breathing through a dust respirator, will be experienced
20Inspection and Maintenance Before going underground examine your self-rescuer for any external damageIf it is damaged, replace it with another one
21Inspection and Maintenance Should the self-rescuer be damaged while underground, it may be impossible in cases of emergency to remove the respirator from the containerIn this case, the wearer can still breathe with the filter in the container
22Inspection and Maintenance The standard 30 CFR states an effective inspection program must be established by the operator and include both a visual inspection and weighing of the device
23Inspection and Maintenance A visual inspection serves to identify surface defects, such as a crushed case or broken sealWeighing is necessary because it is the most reliable test in determining the serviceability of a self-rescuer
24Inspection and Maintenance The inspection program for weighing self-rescuers shall not exceed a 90-day period and provide a record of weight for each deviceThe weight gain should not be 10 or more grams
25Miner’s Responsibility Remove the self-rescue device if they are not in good condition or any of the following exists:A device has a crushed or deeply dented caseA device has dents or damage around the seal areaA device has a broken seal or has lost its vacuum sealA device has a weight gain of 10 grams or more above the manufacturer’s weight imprinted
26W-65 Self-Rescuer Quiz When should a person use the self-rescuer? The rescuer should be used immediately at the first indication of a fire or explosion even though no smoke is visible.
27W-65 Self-Rescuer QuizHow long will the self-rescuer protect you once it is activated?One hour
28W-65 Self-Rescuer Quiz When should you remove the self-rescuer? Do not remove the self-rescuer until you are in fresh air.
29W-65 Self-Rescuer Quiz What is the use life of a self-rescuer? Remove the self-rescuer from service if it has a weight gain of 10 grams or more above the manufacturer’s weight imprinted on the self-rescuer case.
30W-65 Self-Rescuer QuizIf the container does not come off when you open the device, what should you do?If the container is damaged, it may not be possible in an emergency to remove the respirator from the container. The wearer can still breathe with the filter in the container.
31W-65 Self-Rescuer QuizIf the device begins to get hot, what should you do?The wearer must keep the self-rescuer in place regardless of how hot it becomes. To remove a self-rescuer under such circumstances would almost certainly result in death.
32W-65 Self-Rescuer Quiz Why was the self-rescuer designed? As the name implies, the self-rescuer is intended to help the wearer escape.
33W-65 Self-Rescuer QuizFrom what gases does the self-rescuer protect you?The self-rescuer is designed to protect the wearer from carbon monoxide present in the air following a fire or an explosion. It does not provide oxygen.
34W-65 Self-Rescuer QuizAfter you don the self-rescuer, what should you do?Go to fresh air immediately.
35W-65 Self-Rescuer QuizShould the self-rescuer be used t o fight fires?No
