All Turning, Grooving, Milling, Threading and Boring Tool Holders

SECTION 2: Hazards identification

Directive 67/548/EEC: All Tools Holders in their solid state and under normal conditions do not present an inhalation, ingestion or skin hazard. However, operations resulting in fume or dust formation such as welding, sawing, brazing, grinding and machining may present health hazards.

Principle Routes of Exposure

Inhalation and skin contact F

Potential chronic health

Chronic and prolonged inhalation of high concentrations of fumes or dust of the 1 0 following elements may lead to the conditions listed: H 2 1 0 0 R Chromium or nickel- various forms of dermatitis, inflammation and/or ulceration of the upper respiratory tract and possibly cancer of nasal passages and lungs. Based on available information, there does not appear to be any evidence that exposure to welding fume induces human cancer. Cobalt- Chronic exposure to respirable dusts, fumes and mists containing cobalt carry the potential to cause permanent respiratory diseases, including occupational asthma, interstitial pneumonitis and fibrosis (hard-metal disease) and emphysema. Symptoms include productive cough, wheezing, dyspnea upon exertion, pleuritic chest pain, nausea and weight loss. Skin sensitization is noted in a small percentage of cases. Reports originating outside of the industry suggest that ingestion of significant amount of cobalt can cause blood, heart and other organ effects. Long-term or repeated exposure to dusts may have effects on the central nervous system. Copper- irritation of the upper respiratory tract and metal-fume fever, presents symptoms similar to a flu-like illness. Iron (as an iron oxide)- prolonged exposure may produce pulmonary effects and/or Siderosis. Lead - prolonged exposures can cause behavioral changes, kidney damage, peripheral neuropathy characterized by decreased hand grip strength and adverse reproductive effects. Manganese- bronchitis, pneumonitis, lack of coordination. Tungsten- some evidence of pulmonary involvement such as cough (see also cobalt). Vanadium (as vanadium pentoxide)- eye and respiratory tract irritant.

Potential Acute Health Effects

Excessive inhalation of metallic fumes and dusts may result in irritation of eyes, nose, and throat. High concentrations of fumes and dusts of iron oxide, manganese, copper, zinc and lead may result in metal fume fever. Typical symptoms consist of a metallic taste in the mouth, dryness and irritation of the throat, chills and fever. These symptoms may persist from 12 to 48 hours. Carcinogenic Assessment: Chromium ACGIH A4 - Not classifiable as human carcinogen. IARC GROUP 3 -Unclassifiable as to carcinogenicity to humans. Cobalt ACGIH A3 - Confirmed animal carcinogen. IARC GROUP 2B - Possibly carcinogenic to humans. Lead ACGIH A3 - Confirmed animal carcinogen. IARC GROUP 2B - Possibly carcinogenic to humans. NTP 2 - Reasonably anticipated to be a human carcinogen. Nickel ACGIH A5 - Not suspected as human carcinogen. IARC GROUP 2B - Possibly carcinogenic to humans. NTP 2 - Reasonably anticipated to be a human carcinogen. NIOSH - Carcinogenic.
