Dust masks for woodworking are one of the labor protection tools to ensure safety for people. However, users still do not fully understand things that need to do when using a dust mask for woodworking.
- How to check adhesion:
Step 1: Check whether the gas mask has a suction device and an exhaust valve.
Step 2: Check that both suction devices and exhaust valves are in good working condition.
Step 3: Put on the gas mask.
Step 4: Tighten the belt over the head until the gas mask attaches to the wearer’s face comfortably.
Step 5: Airtightness test
How to check negative pressure and positive pressure:
Negative pressure is created in the gas mask when the wearer inhales.
Positive pressure is created in the gas mask when the wearer breathes.
Step 1: cover the suction device of the gas mask with your palm, using a small piece of plastic or a specially made equipment.
Step 2: create a vacuum in the gas mask by breathing in slightly and holding your breath for 10 seconds.
Step 3: Check the pressure
Negative pressure: the airtight respirator will move close to the face, remain in this position, and no air will escape from the side or from above or below. If the mask does not move inwards to the face or does not remain in that position, it will have gas leaking. Therefore, you should check the exhaust valve, change the location of the gas mask, and adjust the straps over the head.
If positive pressure: airtight respirator will expand and remain in this position, and no air will escape from the side or from above and below. If there is air coming out, check the suction device, change the location of the respirator, and adjust the strap over the head.
Step 4: Please recheck the airtightness.
- Clean the gas mask while working:
Sometimes the wearer may clean the gas mask during his / her working hours. Use a few minutes after the break or mealtime to clean the inside of the respirator using a wet cloth.
- Clean the gas mask regularly
Step 1: Remove the filter:
The filter should not be wet or wet.
Clean the outside of the filter with a wet cloth
Do not clean the inside of the screen
Replace the filter if paint or any other contaminant slowly contaminate it.
Step 2: You remove the straps over the head, washers, and exhaust valves.
Step 3: Dip the mask in warm water and wash carefully. Do not use hot water because it may change the shape of the cover. Note:
Use mild soap
Use a soft brush to remove hard dust and stains
Never use organic solvents such as pine oil or gasoline to clean your respirator.
Step 4: Use clean, warm water to remove soap bubbles and disinfectant from the mask.
Step 5: Dry the mask using a clean surface or hanging on a clothesline in the following steps:
Place the cover where the shape of the cover does not change during the drying process.
Use a soft, lint-free cloth to wipe excess moisture before drying the mask completely.
Step 6: Rinse the drain valve and seal carefully
Dry in a humid atmosphere. Set to dry in position will help maintain the original shape of the exhaust valve.
Replace any bent or damaged exhaust valve with a new valve.
Step 7: Replace the parts of the respirator mask with genuine parts certified by the manufacturer. Assemble the pieces in the correct order.
Step 8: reassemble the filter.
(Note: The procedures for cleaning and disinfecting a respirator mask may vary. Please refer to the manufacturer’s instructions before cleaning the respirator.)
Store dust masks for woodworking
Make sure your respirator mask is clean by storing it in a resealable plastic bag.
Store the respirator in a resealable plastic bag to protect it from dust and pollutants.
- Make sure plastic bags with zippers are clean.
- Confirm that the plastic bag can be pulled back and not damaged.
- Replace plastic bags if necessary.
Make sure that the respirator mask and the belt do not get stretched during storage.
Do not store the respirator mask with other equipment. The device may damage gas masks.
When storing the respirator in a vehicle or a location prone to temperature fluctuations, open the plastic bag with a soft pull cover to prevent condensation.
Management of disposable respirators
Single respirator: Single-use respirator type of cup or fold type. Some have exhaust valves; Some other brands do not have this feature.
How to maintain it:
- The gas mask has two straps to fasten the cover to the face. Always have both straps.
- Wear straps under helmets, hats, or earmuffs. Wearing improper thongs can bend the mask part of the gas mask or tighten belts, which can lead to poor adhesion to the face.
- Store the cup-shaped respirator in its original shape. Do not fold as folding can cause the filter to create and result in poor adhesion to the face. Folding gas masks can be folded for storage.

- How to measure mask:
Step 1: Place the gas mask in the palm with the cover of the hood on the fingers.
Step 2: Put the gas mask on the nose, mouth, and chin.
Step 3: Use your other hand to pull the upper straps above the ears and behind the head
Step 4: Pull the lower straps to the back of the head and below the ears. The bottom straps of some types of gas masks with clamps can tighten behind the head.
Step 5: Use the tip of your finger to gently press the nose of the cover down towards his nose
Step 6: Close the respirator mask with both hands and check the adhesion. Gas masks are slightly wrinkled when inhaled; No air comes out when exhaling.
- Gas pressure test:
Step 1: Use both hands to cover the entire gas mask or use a plastic cup provided by the manufacturer to check for airtightness.
Step 2: If the gas mask comes with a drain valve, use your palm to seal it.
Step 3: Put on a gas mask and try breathing in, breathing out. If airtight, the cover will be slightly wrinkled when inhaled, and no gas will exhale.
Step 4: If air leaks around the nose, press on the side of your nose to make the mask fit snugly. If air leaks out at the corners of the gas mask, adjust the straps.
Step 5: If air tightness is not guaranteed, notify supervisors and leave the mask outside the contaminated area.
Many people still think that gas masks are just an ordinary mask. Therefore, attention to the functions or use of them is neglected. Hopefully, after this article, people will pay more attention when using gas masks.
