What form of contact with chemicals can lead to health risks?

Inhalation and skin contact with chemicals can lead to significant health risks because these two routes of exposure are common ways that harmful substances can enter the body. When a person inhales chemical vapors, fumes, or dust, these substances can reach the lungs and enter the bloodstream, potentially causing various respiratory issues, systemic toxicity, or other health-related problems.

Similarly, skin contact can result in the absorption of chemicals through the dermal layers, which can lead to localized effects like irritation or chemical burns, as well as systemic issues if the substance is highly permeable or toxic. The skin acts as a barrier, but it is not impenetrable for all chemicals, especially those designed to be absorbed, and prolonged or significant contact can enhance the risk.

In contrast, staying indoors may reduce exposure to outdoor chemicals, but it does not eliminate the risk of exposure to indoor pollutants. Proper ventilation is crucial for reducing concentrations of inhaled chemicals in enclosed spaces. Using gloves is a protective measure that minimizes skin contact with hazardous materials, but it does not address the inhalation route of exposure. Therefore, recognizing inhalation and skin contact as primary contact routes highlights the importance of safety practices when handling chemicals.
