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

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

• 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.
