These guidelines are derived from documents published by the Iowa department of public health childhood lead poisoning prevention program entitled "eliminating lead based paint hazards".
      1.   Remove lead based paint carefully! You should never dry scrape or dry sand lead based paint on the inside or outside of your home. Always mist surfaces with water before scraping or sanding them. Use a tarp or piece of plastic to catch paint chips when you are working on the outside of your house. This will keep paint chips from falling on the soil. If you are working outside, close windows to prevent lead dust from entering the home.
      2.   Do not sandblast or waterblast lead based paint on the outside of your home. You do not want the paint chips to end up all over your yard or the neighbor's yard. Sandblasting and waterblasting is safe only if you have a special machine that will catch the paint chips.
      3.   Remove furniture, drapes, and if possible, carpet from the room you will work in before starting work. Cover the floor and furniture that cannot be removed from the room with a sheet of six (6) mil plastic. Seal each room from the rest of the house with plastic while working in it. Be careful not to track dust and paint chips into other areas of the home.
      4.   Wear a negative pressure, half mask respirator with a magenta (purple) HEPA filtration canister. You can buy these respirators at auto parts stores (used for brake and clutch work). The respirator will say "HEPA Filters - Asbestos Approved". Be sure to read the instructions for positive and negative face fit tests and for cleaning the respirator. If the respirator does not fit properly, it will not protect you. It will also not protect you if it is dirty. These masks do not protect against organic vapors from heat guns or paint strippers. So, use heat guns and paint strippers only where there is good ventilation. This will help disperse any organic vapors from the strippers or from heating the paint.
      5.   Replace the filters on the respirator if they are damaged. You should also replace them if it gets hard to breathe. This means that the filters are plugging. Wash the face piece (without the filters) with mild soap. Store the respirator in a bag outside of the work area.
      6.   If you have asthma, emphysema, or heart problems, do not try to wear a respirator. Take off the respirator immediately if you feel short of breath. If you have a perforated eardrum that has not been repaired, this respirator will not protect you from inhaling lead dust.
      7.   If you will be using a heat gun, make sure it is a low temperature heat gun that operates below one thousand one hundred degrees Fahrenheit (1,100°F).
      8.   Do not eat, drink, or smoke until you have left the work area and thoroughly washed your hands and face. Take a shower, wash your hair, and change clothes before coming in contact with others.
      9.   Keep pregnant women and children out of the room if you are working on a small project. A small project would be working on only a few surfaces in one room at a time. For larger projects, keep pregnant women and children out of the home until you complete the job.
      10.   After you complete the job, wash all surfaces thoroughly with any household detergent. Vacuum with a HEPA vacuum or a regular vacuum with microfilter bags. Shampoo carpets using a machine that pumps liquid into the carpet and pulls it back out.
      11.   Place paint chips, dust, and pieces of wood in a plastic bag at the end of each day. Put this with your garbage that will go to the landfill.
After you complete work to eliminate lead based paint hazards, you must maintain the remaining lead based paint in good condition. You should also frequently clean the house. Wash floors, window sills, areas between the windows, and other places where dust and dirt accumulate at least once a week. Check the condition of lead based paint frequently. You need to repair paint when it begins to deteriorate. (Ord. 08-4315, 9-9-2008)
