The Benefits of Gas Masks

A gas mask is an item of personal protective equipment that protects the wearer from inhaling airborne pollutants and toxic gases. It usually forms a sealed cover over the nose and mouth, but may also protect other vulnerable soft tissues of the face.

Inhalable gases can cause a range of harmful effects, including irritation, choking, lung damage and even death. Inhaled particles, such as bacteria, viruses and other microscopic organisms, can also harm the wearer’s health by entering their bloodstream or causing inflammatory reactions. Fortunately, a gas mask is able to filter out the most dangerous contaminants.

The CM-6 mask combines cutting-edge engineering and design to deliver superior comfort and performance. Its bromobutyl rubber is hypoallergenic and provides a snug fit. Its flexible 5-point harness offers a wide range of adjustments, and its left or right inhalation chamber can be fitted with a variety of filters compatible with EN 148-1 standard 40 mmx1/7″ threads. A glass insert can be attached for use with eyewear, and the unused inhalation chamber can be closed off with a filter plug.

The filtration efficiency (EF) of a mask depends on several factors, such as aerosol particle size and type, gas flow and pressure differential, and fitness. A quantitative fitness test uses a breathing simulator and measures the concentration of inhaled particles inside and outside the mask during a number of tasks, such as deep breathing, head side to side movement, talking and bending over. Other factors affecting EF include the temperature, humidity and electrostatic attraction of the filter material, and decontamination methods, such as hydrogen peroxide or chlorine dioxide.
