Lead Paint Removal >> Dispose Of Lead Paint Chips

The permissible exposure limit(PEL) set by the standard is 50 micrograms of lead per cubic meter of air (50 µg/m3), averaged over an 8-hour workday. E. Action level: The interim final standard establishes an action level of 30 micrograms of lead per cubic meter of air(30 µg/m3), averaged Dispose Of Lead Paint Chips over an 8-hour workday. 

The action level triggers several ancillary provisions of the standard such as exposure monitoring, medical surveillance, and training. II. Health Hazard Data A. Ways in which lead enters your body. When absorbed into your body in certain doses, Dispose Of Lead Paint Chips lead is a toxic substance. The object of the lead standard is to prevent absorption of harmful quantities of lead. 

The standard is intended to protect you not only from the immediate toxic effects of lead, Dispose Of Lead Paint Chips but also from the serious toxic effects that may not become apparent until years of exposure have passed. Lead can be absorbed into your body by inhalation (breathing) and ingestion (eating). Lead (except for certain organic lead compounds not covered by the standard, such as tetraethyl lead) is not absorbed through your skin. 

When lead is scattered in the air as a dust,fume or mistit can be inhaled and absorbed through yourlungs and Dispose Of Lead Paint Chips upper respiratory tract. Inhalation of airborne lead is generally the mostimportant source of occupational lead absorption. You can also absorb lead through your digestive system if lead gets into your mouth and is swallowed. 

If you handle food, cigarettes, chewing tobacco, or make-up which have lead on them or handle them with hands contaminated with lead, this will contribute to ingestion. A significant portion of the lead that you inhale or Dispose Of Lead Paint Chips ingest gets into your blood stream. Once in your blood stream, lead is circulated throughout your body and stored in various organs and body tissues. 

Some of this lead is quickly filtered out of your body and excreted, but some remains in the blood and othertissues. As exposure to lead continues, Dispose Of Lead Paint Chips the amount stored in your body will increase if you are absorbing more lead than your body is excreting. Even though you may not be aware of any immediate symptoms of disease, this lead stored in yourtissues can be slowly causing irreversible damage, first to individual cells, then to your organs and whole body systems. 

B. Effects of overexposure to lead (1) Short term (acute) overexposure. Lead is a potent, Dispose Of Lead Paint Chips systemic poison that serves no known useful function once absorbed by your body. Taken in large enough doses, lead can kill you in a matter of days. A condition affecting the brain called acute encephalopathy may arise which develops quickly to seizures, coma, and death from cardiorespiratory arrest. 

A short term dose of lead can lead to acute encephalopathy. Short term occupational exposures of this magnitude are highly unusual, but not impossible. Similarforms of encephalopathy may, Dispose Of Lead Paint Chips however, arise from extended, chronic exposure to lower doses of lead. There is no sharp dividing line between rapidly developing acute effects of lead, and chronic effects which take longer to acquire. 

Lead adversely affects numerous body systems, and causes forms of health impairment and disease which arise after periods of exposure as short as days or Dispose Of Lead Paint Chips as long as several years. (2) Long-term (chronic) overexposure. Chronic overexposure to lead may result in severe damage to your blood-forming, nervous, urinary and reproductive systems. 

Some common symptoms of chronic overexposure include loss of appetite, metallic taste in the mouth, anxiety, constipation, nausea, pallor, excessive tiredness, weakness, insomnia, headache, nervous irritability, muscle and Dispose Of Lead Paint Chips joint pain or soreness, fine tremors, numbness, dizziness, hyperactivity and colic.In lead colic there may be severe abdominal pain. 

Damage to the central nervous system in general and Dispose Of Lead Paint Chips the brain (encephalopathy) in particularis one of the most severe forms of lead poisoning. The most severe, often fatal, form of encephalopathy may be preceded by vomiting, a feeling of dullness progressing to drowsiness and stupor, poor memory, restlessness, irritability, tremor, and convulsions.

It may arise suddenly with the onset of seizures, Dispose Of Lead Paint Chips followed by coma, and death. There is a tendency for muscular weakness to develop at the same time. This weakness may progress to paralysis often observed as a characteristic "wrist drop" or"foot drop" and is a manifestation of a disease to the nervous system called peripheral neuropathy. 

Chronic overexposure to lead also results in kidney disease with few, if any, symptoms appearing until extensive and Dispose Of Lead Paint Chips mostlikely permanent kidney damage has occurred. Routine laboratory tests reveal the presence of this kidney disease only after about two-thirds of kidney function is lost. When overt symptoms of urinary dysfunction arise, itis often too late to correct or prevent worsening conditions, and progression to kidney dialysis or death is possible. 

Chronic overexposure to lead impairs the reproductive systems of both men and women. Overexposure to lead may result in decreased sex drive, impotence and Dispose Of Lead Paint Chips sterility in men. Lead can alterthe structure of sperm cells raising the risk of birth defects. There is evidence of miscarriage and stillbirth in women whose husbands were exposed to lead or who were exposed to lead themselves. 

Lead exposure also may resultin decreased fertility, and abnormal menstrual cycles in women. The course of pregnancy may be adversely affected by exposure to lead since lead crosses the placental barrier and Dispose Of Lead Paint Chips poses risks to developing fetuses. Children born of parents either one of whom were exposed to excess lead levels are more likely to have birth defects, mental retardation, behavioral disorders or die during the first year of childhood. 

Overexposure to lead also disrupts the blood-forming system resulting in decreased hemoglobin (the substance in the blood that carries oxygen to the cells) and Dispose Of Lead Paint Chips ultimately anemia. Anemia is characterized by weakness, pallor and fatigability as a result of decreased oxygen carrying capacity in the blood. (3) Health protection goals ofthe standard. 

Prevention of adverse health effects for most workers from exposure to lead throughout a working lifetime requires that a worker's blood lead level (BLL, also Dispose Of Lead Paint Chips expressed as PbB) be maintained at or below forty micrograms per deciliter of whole blood (40 µg/dl). The blood lead levels of workers (both male and female workers) who intend to have children should be maintained below 30 µg/dl to minimize adverse reproductive health effects to the parents and to the developing fetus.
