Safety GuidelinesUtilizing and Storing Paint Thinner

The vapors are especially hazardous. In fact, the American Conference of Governmental Industrial Hygienists set a specific threshold limit for this type of compound, which is the maximum concentration that can be breathed by any person in a 40-hour work week.

6. Keep Away From Combustible Materials and Heat

Paint thinner is a volatile substance that must be kept away from combustible materials, liquids, heaters, and open flames.

7. Never Consume Food in the Vicinity

Never eat or drink in the work area when you are handling paint thinners. The food substances can easily be contaminated and you may unknowingly ingest paint thinner.

If you have paint thinner or oil-based paint on your hands, and you want to eat between tasks, leave the room and wear latex or nitrile gloves on your hands while you eat.
