INSTRUCTIONS FOR USE
Respirator equipped with calcium hydroxide in the cleaning tank, the system must be closed. Otherwise, the failure of the absorbent will lead to carbon dioxide poisoning accidents.
The calcium hydroxide filled in the cleaning tank must be tested and qualified, and the unused time shall not exceed three months. If it exceeds the prescribed time limit, carbon dioxide poisoning accidents may occur during use.
The cleaning tank must be refilled with calcium hydroxide after one use. Even if the wearing time is short, new calcium hydroxide must be replaced.
It is strictly forbidden to use in the environment below -20℃ and above 60℃. Otherwise, it will damage the performance of the respirator and cause personal accidents.
It is strictly forbidden to use the respirator in the environment where the pressure exceeds 0.05MPa (gauge pressure). Otherwise, oxygen poisoning accidents may occur under high pressure.
In the filling of oxygen cylinders and other operations, it is strictly forbidden to touch open flames or be contaminated with grease. Otherwise, it will cause burning and other accidents.
