What is the primary concern regarding dermal exposure to hazardous substances?

The primary concern regarding dermal exposure to hazardous substances is the potential for systemic effects. When hazardous substances come into contact with the skin, they can be absorbed into the bloodstream and distributed throughout the body, potentially affecting internal organs and systems. This systemic absorption can lead to a variety of health issues that might not be immediately apparent as a result of skin contact alone.

In contrast, while direct toxicity to the skin is certainly a concern—such as irritation, burns, or allergic reactions—these effects are often localized. Understanding the systemic implications highlights the need for proper protective measures and handling practices to mitigate risks associated with skin exposure. Monitoring and addressing the potential for systemic effects ensure a comprehensive approach to workplace safety and health.
