OSHA defines the protection provided by respirators in two main categories. The first is the removal of contaminants from the air. This includes particulate respirators, which filter out airborne particles, and air-purifying respirators with cartridges or canisters that filter out chemicals and gases.

The second category protects users by supplying clean, breathable air from an external source. This includes airline respirators, which use compressed air from a remote source, and self-contained breathing apparatus (SCBA), which come with their own air supply.

Liberty Safety™ offers the following types of respiratory protection:

• N-95 Particulate Respirators: These filter at least 95% of airborne particles but are not resistant to oil-based particles.
• Nuisance Masks: Designed to be worn with safety glasses, these masks offer protection against airborne particles such as pollen, dust, and sand.
• 3-Ply Face Masks: Suitable for use when a respirator or surgical mask is not required, these masks provide some protection against airborne particles.

Hazardous substances like gases, solvents, powdered chemicals, and sprays can be found in various physical forms in the workplace. This is why OSHA recommends respiratory protection for millions of workers across the United States.

Respirators safeguard workers from environments with insufficient oxygen, as well as harmful dust, fog, smoke, mist, gas, vapor, and spray exposure. These hazards can lead to serious health issues, including cancer, lung impairment, diseases, and even death.

Air contaminants are generally categorized as particulates or gas and vapor contaminants.

Adhering to the OSHA Respiratory Protection Standard could prevent hundreds of fatalities and thousands of illnesses each year caused by these harmful substances.

Explore the various mask models available to find one that fits well. You shouldn’t have to settle for a mask that doesn’t sit comfortably on your face. It’s a good idea to practice putting on your mask in a clean space before using it in public or at work.

Whichever mask you choose, ensure it:

• Covers your chin, mouth, and nose
• Fits snugly without any gaps
• Does not obstruct your vision
• Is as comfortable as possible

Face masks with ear loops offer several advantages. They tend to be more flexible and can feel more comfortable when worn with work or recreational headgear.

On the other hand, headbands or head straps provide a more secure fit that minimizes leakage. However, their stretchy material can be prone to breaking if overstretched, and they may be more challenging to manage with thick hair.

For best practice, follow the instructions included in the packaging.

Outdoor face masks are recommended in certain situations, so be sure to check your employer’s guidelines and worksite requirements.

When wearing a mask, whether indoors or outdoors, keep the following in mind:

• Ensure it covers both your nose and mouth.
• Make sure it fits snugly to minimize gaps.
• Avoid touching the mask; wash your hands if you do.
• Choose a mask specifically designed for your work environment to reduce the risk of transferring airborne particles.
