Hippocrates found that human children in addition to adults were getting sick; it was he who realized the sickness was from the negative effects from working around lead fumes. Introduced the first air filtering system using a pig bladder. Illness seemed to follow exposure to lead, so by the mid 1800s they started to decrease the use of lead in certain products that humans would come in contact with. 29 CFR 1910.1025 1910.1025(c)(1) The employer shall assure that no employee is exposed to lead at concentrations greater than fifty micrograms per cubic meter of air (50 ug/m(3)) averaged over an 8-hour period.1910.1025(c)(2) If an employee is exposed to lead as long as more than 8 hours in any work day, the permissible exposure limit, as a time weighted average (TWA) as long as that day, shall be reduced according to the following as long as mula: Maximum permissible limit (in ug/m(3))=400 divided by hours worked in the day.
Main exposure pathways: Inhalation, ingestion, in addition to absorption OSHA PEL – .05 mg/m3 NIOSH REL in addition to PEL match OSHA IDLH – 100 mg/m3 Due to the many health concerns, many companies will prohibit women from working in conditions that have a high risk of lead exposure during childbearing years; men are not wholly excluded from this They do this as long as the protection of children that might be born to these women
Target Organs in addition to other health effects that can occur: Kidneys Nervous system Anemia high blood pressure impotence, infertility, in addition to reduced sex drive Lead poisoning Neurological effects Mental retardation have occurred in the children of workers engaged in the occupations where there is lead exposure In the past, lead was used as long as the following: Paint Plumbing Preservatives Gasoline Bullets Determine if there is any lead in campus daycare toys Determine the amount of lead in paint if there is any
Picked two locations to per as long as m test Knee High Day Care in addition to Campus View Apartments Day Care Contacted both in addition to set up times to inspect toys Set up area to per as long as m test Selected toys to be tested Tested toys in addition to analyzed data OSHA Tech Manual Sec. I The Use of Surface Contamination Sampling in Evaluating Safety in addition to Health Programs 29 CFR 1910.132 requires the assessment of the [day care] to determine if it is likely to have [lead] present Controlled Work Area Requiring PPE Controlled Work Area Requiring Special Cleaning Non-controlled Work Area [no PPE required] It was determined that Day Cares are: Non-controlled Work Areas Meaning that there is no reason to believe that there would be an exposure to lead or significant contamination
Instant Lead Testing Swabs Ghost Wipe Patches XFR 1. Squeeze the swab to crush the front glass vial inside. 2. Squeeze the swab to crush the rear glass vial inside. 3. Shake the swab to mix the reagents. 4. While squeezing the swab, rub the surface to be tested as long as approximately 30 seconds. Within one minute, the swab will turn color if the contaminant is present. One wipes the surface that is desired to be tested in addition to then sends sample to the lab as long as further analysis of the contents absorbed.
Uses a radiation source to detect any lead in a 1x 1 surface section. It has the capabilities to accurately detect up to six layers . Measures in mg/cm2 Each room with toys was thoroughly looked in in addition to each type of toy was examined in addition to set aside as suspect or not. Suspect determined by Age of the toy List from EPA Makeup of the toy The XRF was then used in addition to if any reading of lead came up then a second in addition to third test was run with the XRF. These were averaged together. After XRF confirmed, the wipe in addition to instant lead test was used. Any positive readings from these tools in addition to the toy is asked to be removed. The toy is then taken back in addition to sent to a lab if needed Exterior paint was shown to have very high concentration of lead; however, there is NO RISK of exposure. The house has been fully re-sided A stool was found to have small traces of lead Certain paint brush h in addition to les were found to have small traces of lead Little wooden toys had traces of lead
The little wooden stool with traces of lead needs to be s in addition to ed down in addition to repainted Little wooden toys with half the allowed concentration should be taken out in addition to replaced Remediation of the outside of Day Care Has recently been fully re-sided; no way as long as there to be any exposure to the children as the main play area is well away from the house Day Care Administration has been through their toys in addition to removed any that may be suspect already. Continued monitoring by staff in addition to others should be on going especially when new toys are introduced. One day care had a child that tested very high as long as lead in their system. It is thought to come from the home not the day care.
