Security in the machining information about safety during grinding carbide material composition of products containing carbide tungsten hospital carbide and cobalt, and also include titanium carbide, carbide with tantalum, niobium carbide, chromium carbide, molybdenum carbide or vanadium carbide. Some grades contain titanium carbonitride and / or nickel. The exhibition forms of redress process or heat a piece of hard metal or a product made with carbide generates dust or fumes containing dangerous to health, in the case of inhaled, ingested or come into contact with skin and eyes. Acute toxicity The dust generated is toxic when inhaled. This inhalation may cause irritation and inflammation in the respiratory system. It has been found much more acute toxicity during simultaneous inhalation of cobalt and tungsten carbide, compared with inhalation of cobalt alone. Contact with skin may cause irritation and itching. Susceptible humans may experience an allergic reaction. Chronic repeated inhalation of aerosols containing cobalt may cause insurance obstruction of the airways. Source: Paul Ostling. Prolonged inhalation in high concentrations can cause fibrosis or lung cancer. Epidemiological studies indicate that workers previously exposed to high concentrations of tungsten carbide / cobalt are at greater risk of developing lung cancer. Cobalt and nickel are potential sensitizers. A prolonged or repeated contact may cause irritation. Toxic hazards: Risk of serious damage to health by prolonged exposure through inhalation Toxic by inhalation risk of irreversible effects may cause sensitization by inhalation and skin contact Preventive measures’ Avoid Health insurance dust formation and inhalation. Use an adequate local exhaust ventilation to limit exposure of workers to values well below the authorized limits in your country. ‘If you can provide good ventilation, or is not appropriate, use respirators approved for this purpose. ‘Wear safety glasses with side shields when needed. ‘Avoid repeated contact with skin. Use suitable protective gloves. Wash thoroughly the part in contact with the material after handling. a nationwide provider of health insurance, objective is to deliver and design a lower cost alternative which allows individuals and families to have access to high quality healthcare ‘Use appropriate protective equipment. Wash clothes whenever necessary. ‘Do not eat or drink or smoke in work area. Wash thoroughly before eating, drinking or smoking.
