These are areas where there is a social-political responsibility, but with the exception of petrol, the opportunity to influence the situation on a direct personal level is low. With the remaining source of lead poisoning, old paint, the individual is responsible. The British Coatings Federation publish booklets outlining safe procedures. Any paint work from before 1960 should be tested for lead. Testing kits can be bought from some Trade counters, and Merchants.
Lead based paint becomes dangerous when it starts to deteriorate.
Paint flakes and dust can then be taken in through the mouth or lungs. Dry sanding is dangerous. Protective gloves, overalls, and mask, when dealing with lead paint are essential. Safe removal is based on keeping debris as coarse as possible, and contained. Carpets and material that would harbour dust are cleared from the work area.
