Chemical Oxygen Self Rescuer Precautions

1) Before use, the Chemical Oxygen Self Rescuer must be tested to see if it is normal, otherwise it may cause the user's life to be in danger.

2) The mask must be properly worn to ensure effective protection. The respirator must not be used by people with whiskers and glasses.

3) Always pay attention to changes in the pressure gauge during the work of the Chemical Oxygen Self Rescuer. When the cylinder pressure reaches 5, 5 ± 0, 5 MPA, the alarm whistle starts to buzz. When the alarm whistle begins to buzz, it must immediately evacuate the toxic working environment to a safe area, otherwise there will be danger to life.

4) In case of bad and urgent situations (such as injuries or breathing difficulties) or when the user needs additional air supply, open the forced air supply valve (by pressing the air supply valve yellow button). The respiratory flow will increase to 450 liters/minute.
