Lead Base Paint Sampling

LEAD BASED PAINT

Lead reduction is an activity designed to permanently eliminate risks to human health from lead-based paint. The reduction is ordered by a state or local government, and may involve specialized techniques not typical of most residential contractors; for this reason, it is advisable that only an expert and certified agent such as our company Pure Air, can take care of this procedure.

Inspections can determine the existence of lead-based paint through surface in the residences or commercial establishments; The zones or structures more passed by the children and objects that have had some contact with the contaminant, as specified by the client. In accordance with EPA requirements, the inspection should be carried out using documented methodologies and appropriate quality control measures and the results are incorporated into a report. Paint samples should be sent for laboratory analysis to determine their level of contamination.

The EPA requires that only certified companies such as ours can design projects for the renovation and repair of lead paint in homes, commercial premises, nurseries, preschools, universities, among others, built before 1978. In addition, the EPA says only certified companies such as Pure Air are trained, and approved to conduct safe work practices for lead removal.

Who are at risk?

Children

Lead is particularly dangerous to children because their bodies are growing and may absorb more lead than adults; plus their brains and nervous systems are more sensitive to the harmful effects of lead. Babies and young children may also be more exposed to lead as they often put their hands and other objects that may have dust or lead into them in their mouths. Children may also be exposed to lead by eating and drinking food or water containing lead; In the same way, in the use of plates or glasses that contain lead; Inhaling lead dust, lead-based paint or contaminated soil when playing with their toys.

Adults, including pregnant women

Adults may be exposed to lead by eating and drinking food or water containing lead; Using dishes or glasses containing lead. They can also breathe lead dust by spending time in areas where lead-based paint is deteriorating and during renovation or repair work that disrupts painted surfaces in homes and old buildings. Working in one place or participating in hobbies where lead is used, such as the manufacture of colored glasses can increase exposure by using certain popular lead-containing remedies. A pregnant woman's exposure to lead from these sources is of particular concern because it can cause her many problems in the development of her baby.

The EPA uses CDC data to show trends in blood lead levels in children in the United States and the environment.

What are the effects of lead on health?

Lead can affect almost every organ and system in your body. Children six years of age or younger are the most susceptible to the effects of lead.

Children

Even low levels of lead in the blood of children can affect in:

  • Behavior and learning problems
  • Lower IQ and hyperactivity
  • Growth process to make it slower
  • Listening problems
  • Anemia
  • And in some cases lead ingestion can cause seizures, coma and even death.

Pregnant women

Lead can build up in our bodies over time in bones along with calcium. For this reason, during pregnancy, lead is released from the bones as maternal calcium and is used to help form the bones of the fetus. This is particularly true if a woman does not have enough calcium in her diet. Lead can also cross the placental barrier exposing the fetus to lead. This can result in serious effects for the mother and her developing fetus, including:

  • Reduced fetal growth
  • Premature birth

RISK EVALUATION

The risk assessment includes a visual assessment of the condition of the paint in the building, residence or commercial premises. Sampling locations are selected based on usage patterns and visual observations. Dust samples are typically collected in areas such as the entrance, common spaces, kitchen, living room, a child's bedroom and playroom. Samples can be collected from floors, interior window boards (stools), window troughs, (window pits) and other suspect surfaces from contamination. All hazards identified as well as acceptable control measures, including provisional control and degression options.

Pure Air, is EPA certified to inspect lead-based paint. And in accordance with EPA requirements, authorization must be made at least one (1) hour after completion of the reduction activities.

 

The inspector must perform a visual examination to determine:

  1. If all required work is completed,
  2. If all hazards of lead-based paint have been controlled.
  3. There is no visible seated dust, paint chips or debris inside or around the outside. If the visual inspection is satisfactory, sampling of cleaning ducts of the floors, the internal shelves of the windows and of the watering places of the windows.
