Lung Protection in High Risk Environment

KTF Africa supplies high quality respiratory masks for industrial use, construction and high risk environments. The Breathing in of fumes, fine dust, vapours and gases has long term effects on the users lung health and quality of life. Mask classification of respiratory masks is done according to the environment they are being used.  The masks are either re-usable and disposable.

Choosing a respirator  it is equally important to check: 

  • First it should fit snugly, covering mouth and nose but leaving eye sight clear
  • The mask needs to fit the job.


Lung Hazards Categories

These are particles that vary in size resulting from the breaking up of solids. The smaller the particle the greater the hazard that it presents.

These are clouds of fine droplets or particles formed by spraying, which can be water or oil based. Mists are often combinations of several hazardous ingredients formed by processes that involve atomisation and consist of tiny liquid droplets. Are organic or inorganic compounds that become airborne and are able to diffuse or spread freely. Gases can travel very far very quickly. These are solid aerosols that are formed when metallic vapours condense on cooling and may be produced by welding, galvanising or similar processes involving hot metal. When an atmosphere is likely to contain less than 19% oxygen, or where conditions may exist in the future to cause this to happen, the area is considered oxygen deficient and a hazard.




  1. What is the oxygen content?
  2. Are there asphyxiants present?
  3. How is the atmosphere immediately dangerous to life or health?
  4. How is the atmosphere corrosive or likely to become so?
  5. How is the atmosphere explosive or likely to become so?
  6. How is there a potential of permeation of air contaminants?
  7. What is the contaminant?
  8. Are there climatic extremes?
