Which precaution is the least effective against occupational dermatoses?

1. Frequent washing of the face and hands with an organic solvent followed by soap and water

2. Use of good housekeeping and frequent washing with soap and water

3. Good hygiene practices and use of gloves

4. Frequent washing with soap and water and the use of barrier cream

The correct answer is: Frequent washing of the face and hands with an organic solvent followed by soap and water

Frequent washing of the face and hands with an organic solvent followed by soap and water is considered the least effective precaution against occupational dermatoses because using an organic solvent can strip away essential oils and natural moisture from the skin, potentially leading to irritation or even damage. This action can make the skin more susceptible to harmful substances and allergens typically present in occupational settings. In contrast, maintaining good hygiene practices, such as washing with mild soap and water, using gloves, and employing barrier creams, provides protection against irritants and allergens. These methods help to keep the skin intact, hydrated, and less susceptible to occupational dermatoses. Therefore, while washing is essential, combining it with gentle methods rather than harsh solvents is crucial for effective skin protection in the workplace.
