  • Always keep out of reach of children and animals;

  • Do not take in orally - harmful if swallowed. Seek medical attention and do not induce vomiting;

  • If accidental contact with skin, wash immediately with soap and water or a good quality skin cleaner;

  • If accidental contact with eyes, rinse immediately with plenty of water and seek medical advice;

  • Do not let a freshly painted room be occupied, particularly not by older people, children, or pets;

  • Wear a respirator if the area being painted cannot be adequately ventilated, and work for short periods only;

  • Ventilate the area to be painted, opening all doors and windows and using fans during application and drying;

  • Protect floors with cloth dropcloths, not plastic, which is far more slippery;

  • Do not paint or store paint near any heat source such as a water heater or fireplace, and never smoke while painting;

  • Make sure your ladder is in good shape. Set the legs on an even surface and lock the cross braces. Do not stand on the top of the ladder nor on the utility shelf. If you are having difficulty reaching a spot, get down from the ladder and move it rather than leaning out;

  • Clean up carefully and thoroughly when you are done for the day;

  • If rags have alkyd paint or thinner on them, leave them to dry outside to avoid any chance of spontaneous combustion;

  • Choose an area inaccessible to children and pets, and when they are thoroughly dry, take them to a toxic-waste dump site.
