Cadmium (Cd) is a soft, malleable, bluish white metal found in zinc ores, and to a much lesser extent, in the cadmium mineral greenockite. Most of the cadmium produced today is obtained from zinc byproducts and recovered from spent nickel-cadmium batteries.

2024年4月8日 · The PELs listed in 29 CFR 1910.1000 Table Z-2 for cadmium fume and cadmium dust apply to any operations or sectors for which the Cadmium standard, CFR 1910.1027, is stayed or otherwise not in effect. Notes: CARCINOGEN (Ca): REDUCE EXPOSURE TO LOWEST FEASIBLE CONCENTRATION (LOQ 0.1 mg/m³). See Appendix A, NIOSH Potential Occupational Carcinogens

Hazardous decomposition products: The heated metal rapidly forms highly toxic, brownish fumes of oxides of cadmium. C. Spill, Leak and Disposal Procedures . 1.

Occupational exposure to cadmium can lead to a variety of adverse health effects including cancer. Acute inhalation exposure (high levels over a short period of time) to cadmium can result in flu-like symptoms (chills, fever, and muscle pain) and can damage the lungs.

Cadmium, a naturally occurring element found in the earth’s crust, was discovered in 1817, but was not used commercially until the end of the 19th century. This soft, silver-white metal was first used in paint pigments and as a substitute for tin in World War I. Today, about three-fourths of cadmium is used as an electrode

Appearance: Cadmium metal - soft, blue-white, malleable, lustrous metal or grayish-white powder. Some cadmium compounds may also appear as a brown, yellow, or red powdery substance. Health Hazard Data

metal fume. Brazing is a metal-joining process where only the filler metal is melted. Welder using local exhaust ventilation to remove fume from breathing zone.

2020年12月18日 · NIOSH: Pocket Guide to Chemical Hazards - Cadmium fume (as Cd) Literature References ACGIH: Documentation of the Threshold Limit Values (TLVs) and Biological Exposure Indices (BEIs) - Cadmium [7440-43-9] and compounds, as Cd. See annual publication for most recent information.

The most effective way to prevent exposure to a hazardous metal such as cadmium is through elimination or substitution. Substitution with viable, less toxic alternatives to cadmium is available for rechargeable batteries (nickel-metal hydride), plating (zinc, vapor-deposited aluminum), pigments (cerium sulfide), and plastics stabilizers.

Cadmium is an extremely toxic metal commonly found in industrial workplaces, particularly where any ore is being processed or smelted. Several deaths from acute exposure have occurred among welders who have unsuspectingly welded on …
