effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher)
<br />than outdoors. VOCs are emitted by a wide array of products numbering in the thousands.
<br />Examples include: paints and lacquers, paint strippers, cleaning supplies, pesticides, building
<br />materials and furnishings, office equipment such as copiers and printers, correction fluids and
<br />carbonless copy paper, graphics and craft materials including glues and adhesives, permanent
<br />markers, and photographic solutions.
<br />Health effects include eye, nose, and throat irritation; headaches, loss of coordination, nausea;
<br />damage to liver, kidney, and central nervous system. Some organics can cause cancer in animals;
<br />some are suspected or known to cause cancer in humans. Key signs or symptoms associated
<br />with exposure to VOCs include conjunctival irritation, nose and throat discomfort, headache,
<br />allergic skin reaction, dyspnea, declines in serum cholinesterase levels, nausea, emesis, epistaxis,
<br />fatigue, and dizziness.
<br />Polycyclic Aromatic Hydrocarbons (PAHs)
<br />PAHs are a group of over 100 different chemicals that are formed during the incomplete burning
<br />of coal, oil and gas, garbage, or other organic substances like tobacco or charbroiled meat.
<br />PAHs are usually found as a mixture containing two or more of these compounds, such as soot.
<br />Some PAHs are manufactured. These pure PAHs usually exist as colorless, white, or pale
<br />yellow-green solids. PAHs are found in coal tar, crude oil, creosote, and roofing tar, but a few
<br />are used in medicines or to make dyes, plastics, and pesticides.
<br />Mice that were fed high levels of one PAH during pregnancy had difficulty reproducing and so
<br />did their offspring. These offspring also had higher rates of birth defects and lower body weights.
<br />It is not known whether these effects occur in people. Animal studies have also shown that
<br />PAHs can cause harmful effects on the skin, body fluids, and ability to fight disease after both
<br />short- and long-term exposure. But these effects have not been seen in people. The
<br />Department of Health and Human Services (DHHS) has determined that some PAHs may
<br />reasonably be expected to be carcinogens. Some people who have breathed or touched
<br />mixtures of PAHs and other chemicals for long periods of time have developed cancer. Some
<br />PAHs have caused cancer in laboratory animals when they breathed air containing them (lung
<br />cancer), ingested them in food (stomach cancer), or had them applied to their skin (skin cancer).
<br />PHYSICAL HAZARDS
<br />General physical hazards associated with operating and working in the vicinity of heavy
<br />equipment will be present at the site (i.e. drilling, sampling and decontaminating equipment).
<br />These hazards will be minimized by allowing only trained, qualified, and licensed personnel to
<br />operate the heavy machinery. Underground utility hazards will also be present at the site.
<br />These hazards will be minimized by contacting GPRS and facility personnel to identify
<br />underground product, electrical, natural gas and sewer lines etc. prior to the beginning of
<br />construction. In the event that previously unidentified lines are discovered, work will be
<br />stopped immediately until proper identification can be made. Safe work practices in compliance
<br />with OSHA standards and this document will be used at all times. The following table lists the
<br />anticipated physical hazards and the associated safety rules for proper control.
