Patinas are made up of toxic chemicals that can be harmful if inhaled, or if it comes into contact with skin or eyes, and they are flammable. All proper safety attire and precautions must be taken when using patinas. As a good rule of thumb, any equipment you would wear or use in a chemical science lab should also be used when applying patina chemicals, including gloves and goggles, and proper ventilation should be used. All work surfaces should be protected with non porous materials to protect them while working with patinas. If using patinas on wearable items, the chemical should not be applied to any part of the object that will be in contact with skin, even if it is sealed, and they should never be used on items that are used with food. Be sure to use a proper sealant when the patination is complete to protect it.
