Final answer:
In the context of metalworking fluids, hazardous substances such as chlorinated aliphatic hydrocarbons and cadmium can present significant health risks. These chemicals, if mishandled, can be corrosive and toxic. Proper handling and adherence to safety standards and regulations are crucial for worker safety.
Step-by-step explanation:
Metalworking fluids (MWFs) serve as coolants and lubricants in the metalworking industry. They can be composed of various chemicals that pose several health risks to those who handle them without proper protection. Exposure to MWFs can lead to respiratory issues, skin conditions, and other health problems if they contain hazardous substances such as chlorinated aliphatic hydrocarbons, which can be quite corrosive to tissue and metals alike. It is essential to handle these substances with care and use appropriate PPE (Personal Protective Equipment).
Examples of hazardous ingredients in metalworking fluids include formaldehyde, which is a known carcinogen, and dioxins, which can lead to a range of adverse health effects. Substances like cadmium are also often present, which is toxic and harmful to the human body, especially the kidneys and bones. Industries must adhere to the OSHA List of Highly Hazardous Chemicals when managing or disposing of these fluids.
Furthermore, MWFs can become contaminated with other substances during use, such as heavy metals from the workpieces being processed. Workers must be adequately trained in handling these fluids and be aware of the potential risks involved.
