Operation Manual of ZL60 Filter Self-Rescuer （20090512）
A． Introduction
1. Application
ZL60 Filter Self-Rescuer （short for self-rescuer）applies to no coal, gas and carbon dioxide outburst mine. The oxygen concentration in the ambient atmosphere should not less than 18%, carbon monoxide concentration not more than 1.5%, and no other poison gas exits. It is a protective device for personal breathing which can be used to protect from carbon monoxide poisoning in a fire or gas explosion at the mine environment. Operating personnel must carry about it for emergency. It only used as personal escape.

B. Working principle and Structure
The self-rescuer was designed by the principle that under normal temperature the carbon monoxide in air can generate the carbon dioxide by carbon monoxide accelerant (accelerant, same below) when chemical reaction. The chemical reaction equation is as follows:
The chemical reaction equation reveals that heat has been produced during the reaction, so there is a device in the self-rescuer designed to reduce the temperature.
A canister of the self-rescuer is sealed in a case shell which consists of the upper/bottom shells, sealing ring, sealing strap, unlocking-wrench, waistband suspension loop, sealing stamp and number-plate. The case shell is resistance to collide, that the self-rescuer can be durable to use and storage for a long time. See figure 1 for the structure of the self-rescuer and see figure 2 for canister structure.

Figure 1.
When using the canister, the air contained carbon monoxide enters into the drying agent layer through dust-filtered layer; which can absorb the water in the air effectively so that the accelerant is protected from been poisoning to fail.Then the dried air into accelerant layer to make an oxidation reaction, oxidizing.poisonous carbon monoxide（CO） into innoxious carbon dioxide（CO2）. The innoxious air will cool down,through a temperature reduction net before being breathed by mouthpiece and the exhalation will be directly discharged via an exhalation valve. In avoid of rocking and colliding which make a free space of the drying agent layer, the canister is equipped with a set of compensating spring.
The carbon monoxide accelerant complies with requirement of MT 869-2000《Carbon Monoxide Accelerant for Filter Self-Rescuer》
The drying agent complies with requirement of MT 868-2000 《Drying Agent for Filter Self-Rescuer》

D. Application drawing of wearing a self-rescuer
1、Put the belt through the waistband suspension loop of the self-rescuer and fasten the belt.
2、Take down the protection cover firstly when using.
3、Open the red-marked unlocking-wrench andthe sealing strap drop off. The self-rescuer is turned on.
4、Open the upper shell of self-rescuer.
5、Hold of the headband and pull out the canister
6、Take down the safety cap and wear the headband well.
7、Unhinge the nose clip and clip it onto nose.
8、Put the mouthpiece in mouth and bite it. Close lips tightly.
9、Put on the safety cap and pullout from the site.
10、In case the case shell is impaired and unable to take out the canister, just hold the bottom of shell for normal breathing.
