12
Why use respiratory protection?
Welding produce up to 40 g / h of air-borne fume and particulates:
•Our lungs can be exposed to significant contamination
for long periods of time
•We breath 4 000 l air in 8 hour work shift
•Welding fumes include elements which
are dangerous to health
•If unprotected, tiny fume particles can
pass deep into lung structure’s
•This can cause variety of health issues
Hazardous materials:
Enter to body in three ways:
•Ingestion –through the mouth
•Absorption –through the skin, eyes
•Inhalation –through the lungs
Occupational lung diseases are the number one cause of work-related illness in terms
of frequency, severity, and preventability

13
Common route of exposure for most health hazards is inhalation:
•Includes breathing dust, fumes, oil mist, vapors from solvents and various gases
•Some particular chemicals have damaging
effects on lungs
•Others absorbed into bloodstream
and damage various organs
Target organs in human body:
•Central nervous system
•Brain
•Spinal cord
•Heart
•Lungs
•Kidneys
•Liver
Why use respiratory protection?

Airborne pollutants
14
Risks caused by airborne contaminants mainly depend upon:
•Physical, biological and chemical properties of contaminants, particle size and form
•Concentration in ambient air and time of exposure
•Volume of inhaled air
•More rapid respiration, more inhaled airborne contaminants
Size comparison of various types of airborne pollutants ( μm):

Welding fumes
15
Can composition of welding fumes vary?
•Welding fumes contain oxides of metals from welded material
•Fluxes containing silica or fluoride produce amorphous silica, metallic silicates and fluoride fumes
•Mild steel welding contains mostly iron with small amounts of additive metals (Chromium, Nickel, Manganese,
Molybdenum, Vanadium, Titanium, Cobalt, Copper etc.)
•Stainless steels have larger amounts of Chromium and Nickel, lesser amounts of iron
•Nickel alloys have much more Nickel in fume and very little iron
How coatings change composition of welding fumes?
•Vapours or fumes can come from coatings and residues of welded metal
•Some ingredients in coatings can have toxic effects
Ingredients include:
•Metal working fluids, oils and rust inhibitors
•Zinc on galvanized steel ( vaporizes to produce zinc oxide fume )
•Cadmium plating vapours from paints and solvents
•Lead oxide, primer paints some plastic coatings
Metal coatings are a hazardous fume source FresAir welding respirators offer the
ideal protection against the risks of
welding fumes

Air flow test:
•Disconnect air hose from hood
•Cover disconnected end of air hose with hand
•Blower starts to run faster after about 20 seconds
•Audible alarm activates
•Control panels LED diodes start blinking
•Remove hand
•Blower speed should decrease
•If blower speed does not change
•Check unit
