How to wear a gas mask correctly

The steps to wear a gas mask correctly are crucial to ensure personal safety. The following are detailed steps based on the information in the reference article:

Preparation stage:

Check the appearance and performance of the gas mask to ensure that there is no damage or deformation, and the headband is elastic.

Check the shelf life of the gas canister (filter element) and filter cotton to confirm that they are clean and uncontaminated.

Make sure that the exhalation valve plate and inhalation valve of the gas mask are intact, without damage, deformation and cracks.

Wash your hands to ensure that your hands are clean.

Wearing steps:

Open the gas canister cover of the gas mask and put on the mask.

Put the mask part of the mask over your mouth and nose, and cover the mouth and nose with one hand.

Use the other hand to pull up the upper headband so that the headband is comfortably placed on the top of the head.

Pull the lower headband to the back of the neck and buckle the headband buckle.

Buckle the bottom buckle of the gas mask headband behind the neck with both hands to ensure that the mask is firmly fixed on the face.

Adjust the tightness of the headband, pull the end of the gas mask headband to adjust the tightness of the headband so that the gas mask fits well with the face. First adjust the headband on the gas mask head frame, then adjust the neck headband, and be careful not to pull it too tight.

Check whether the wearing is qualified:

Use clean hands to block the mouth of the gas filter canister and observe whether you can't inhale. If you can still inhale normally after blocking the mouth of the canister, or you hear a leak in the gap of the edge of the mask when inhaling, it means that the wearing is not qualified or the gas mask itself is leaking.

You must lower your head to confirm once again, and then raise your head to confirm again. If this requirement is met three times, it means that the overall wearing is compliant. This step is to confirm that the airtightness is still good when the head is at different angles.

Note:

Different gas mask brands and models may vary, so it is recommended to read the instructions carefully or consult customer service staff when using it for the first time or without experience.

Make sure the gas mask fits your face shape. If you feel uncomfortable or have difficulty breathing when wearing it, you should stop using it immediately.

Before and during use, the gas mask should be kept clean and intact, and the filter canister and filter cotton should be replaced regularly.
