When painting with oils, it is important to take some safety precautions. Oil paint takes a little extra consideration, but I love the final results. So I take the time to follow some basic painting safety such as adequate ventilation, keeping paint off my skin, keeping pets and kids away from painting supplies, washing my hands many times, and not eating in the studio.
Okay I'm not so good at that last one. I try to eat before I start painting so that it isn't an issue. I also use good hand cleaner. I haven't painted with gloves yet but am considering it since I am spending a lot more time with my paint.
Keeping hydrated and painting in the shade are important. My outside studio in the summer is unbearable except in the early morning or late evening.
