vomiting, irritation of throat, and body ache. Recovery may take up to 48 hours after the
overexposure.
Nickel and Nickel Compounds : Overexposure may cause metal fume fever, metallic taste, tightness
in chest, nausea, and allergic reaction.
Silica (amorphous) : Dust and fumes may cause irritation of respiratory system, skin, and eyes.
Titanium Dioxide : May cause irritation of respiratory system.
Zirconium : May cause irritation of eyes, nose, and throat.
Long Term (Chronic) Overexposure Effects
Welding Fumes : Excess levels may cause bronchial asthma, lung fibrosis, pneumoconiosis or siderosis
Aluminum Oxide : May cause pulmonary fibrosis and emphysema.
Antimony Compounds: May cause metal fume fever, dermatitis, keratitis, conjunctivitis, and ulceration
and perforation of nasal septum. Guard against Hydrogen coming in contact with antimony; this
can form stibine which is extremely toxic.
Barium : Long term exposure in soluble barium compounds can affect nervous system and also may
affect heart, muscles and circulation.
Chromium : Inhalation of fume with Cr VI compounds, can cause irritation of the respiratory system,
lung damage, and asthma-like symptoms. Swallowing Chromium VI salts can cause severe
injury or death. Dust on skin can form ulcers. Eyes may be burned by Chromium VI compounds.
Chromium III can add to the harmful effects of other chromium compounds. Ulceration and
perforation of septum is also possible on long exposure to chromium compounds.
Fluorides : Long term overexposure to fluorides may lead to bone erosion, osteoporosis and mottling of
teeth.
Iron and Iron Oxides : Long term exposure can cause siderosis that affects pulmonary function.
This is , however, reversible.
Lithium Compounds : Overexposure may cause malformations in the body.
Magnesium and Magnesium Oxide : No long term effect is known.
Manganese and Manganese Oxide : Long term exposure may affect central nervous system .
The symptoms could be muscle spasm, slowness, tremors, change in behavioural patterns, etc.
Overexposure to manganese and manganese compounds can cause irreversible damage to
central nervous system and neurological damages with slurred speech, lethargy, tremor, and
muscular weaknesses.
Nickel and Nickel Compounds : Long term exposure can cause lung fibrosis or pneumoconiosis and
lung and nasal cancers.
Silica (amorphous) : Amorphous silica present in weld8ing fumes can cause pneumoconiosis.
Titanium Dioxide : May cause pulmonary irritation and fibrosis.
Zirconium : May cause pneumoconiosis and pulmonary fibrosis.
Medical Conditions Aggravated by Exposure : Persons with impaired lung and heart functions
such as with asthmatic conditions, heart with pacemaker, or other heart conditions should take
precautions in going near to a welding operation. They should consult a doctor before doing so.
Respirators and other personal protective devices should be used as much as possible.
Emergency and First Aid Procedures: Call for medical aid. Employ first aid techniques recommended
