The recent audiotape released by Al-Qaeda, warning more terrorist attacks inside the United States prompts us to take a pre-emptive measure of safeguarding ourselves by procuring safety equipment like gas masks. Gas mask or respirator masks are an essential part of protecting yourself from biological and chemical attacks.
Respirator masks, however, are also frequently used for industrial safety on a regular basis. They can prevent the chemicals in paint and all manner of airborne pollutants from affecting your respiratory system. For those in the field of agriculture, a quality mask is essential. You can buy quality gas masks from Gas Mask Pro.
There are three ways in which a respirator mask filter and purify the air: particle filtration, chemical neutralization, and chemical absorption. Particle filtration uses a filter to block organisms or substances that are larger than the pores in the filter. Once the filter becomes clogged, it must be replaced to remain effective. Particle filtration gas masks, however, will not be helpful against chemicals and a different approach must be taken.
Chemical neutralization works by using chemicals to react with certain substances, such as chlorine or ammonia, to make it non-toxic. Different filters are available for any type of chemicals that need to be eliminated. These respirator masks are ideal for industrial applications and the filters are coded by the National Institute for Occupational Safety and Health, a branch of the CDC.
