Invisible Gloves
Wear chemical-resistant gloves whenever working with hazard- ous substances. Consider applying a generous amount of hand lotion to your hands just before donning the gloves. The lotion acts as a barrier to corrosive or defatting organic solvents. Gloves sometimes develop leaks, and your “invisible gloves” may be a second line of defense.
