The Roles Of A Lead Inspector In San Diego

By Marcia Marks


It is for the purposes of safety and good health that a lead inspector in San Diego is invited to carry out testing procedures. This is usually due to the state law requirements which were put in place after it was observed that lead has negative implication on human life. The term used to refer to the effect of the chemical in the body is lead-poisoning. This is experienced as a result of elevated levels of this chemical in the blood.

The extent Pb poisoning manifestation depends on the age of the affected person. Children are the most affected, and those poisoned show the following characteristics: stunted growth, attention deficit disorder, low IQ, learning disability among others. Adults are only affected by high levels of Pb, and those that are already poisoned will exhibit the following symptoms: nerves disorder, fertility problem, increased blood pressure just to mention a few. Medical intervention should be sought early enough to avoid fatality from happening.

Detecting the presence of Pb or its elements in a property is not always an easy affair. The process involves a series of sample collection from different parts in the property. The samples are then packaged and labeled appropriately then taken to the laboratory. It is important to note that not all laboratories have the capability of performing the required sample analysis, in this case a certified Pb analysis laboratories should be used.

Sampling is the first and the most important aspect of Pb analysis, and care should be taken when undertaking this stage to yield the best results. There are three methods that are commonly used by Pb inspectors to sample property for Pb. The reason for using different method of sampling is because of the variations in the material used in construction.

The first method is known as dust wipe sampling. Samples are collected from areas such as interior window sills, window troughs and floors. One should avoid surfaces such as bricks, cloth-covered furniture, carpets because they will not produce good results. In this method, one collects dust with a moist wipe after which it is folded with the contaminated side facing inward and this should be done aseptically. When sampling, one should have gloves on.

The next method is known as soil sampling. This done because of the fact that gravitational force tends to pull falling Pb particles to the ground. Peeling paint normally ends up in the ground or even exhausts gases from vehicles in properties next to the road. Soil samples are however not required for compliance to hazardous waste regulations but are necessary for safety within the home.

Samples are then taken of paints used in the home through the last method called paint chipping. This is compulsory as many paints are made using Pb elements. This process can be done either manually or by the use of a portable device that can measure the Pb content in the required surface.

After the analysis has been done and the results are out, the lead inspector in San Diego reads and interprets those results. From there he draws conclusions on the extent of Pb poisoning and suggests what should be done to eliminate hazards. Another sampling is then done to ascertain no lead is present in the area.
