6.3.2.10 Urban Violence and Stray Animals
All contact with transient population, hostile persons, or stray animals will be avoided. If
potentially violent situation arises, project personnel will immediately remove themselves from
the situation and contact the police and the PM.
All site work will be conducted during the day (during day light, prior to sunset). No one will be
allowed to work alone. The buddy system will be utilized at all times.
6.3 BIOLOGICAL HAZARDS
Various biological hazards may be encountered at the Site. These hazards include insects,
spiders, toxic mold, harmful plants, and pathogenic organisms or diseases such as hantavirus.
Due to the location of the site (presence of homeless/transients), there also is a potential of
encountering hypodermic needles and human wastes. Project personnel will avoid contact with
these biological hazards. Sturdy work clothes and steel-toe safety shoes/boots will be worn by
field personnel to defend against unanticipated biological hazards.
6.3.3.1 Insect/Arachnid Bites and Stings
Poisonous insects and insect-like creatures at the site may include red fire ants, bees (honeybees,
bumble bees, wasps, and hornets), mosquitos, and spiders.
Red fire ants may be observed, especially in the vicinity of existing monitoring wells. Do not
stand on, place equipment on, or otherwise disturb the anthills. It is also advisable to place a
four-foot square piece of plywood where personnel need to stand. An insect repellent may be
used if it does not interfere with the desired sampling analyses. Tyvek ® suits can be worn or
latex booties can be taped at the top to the pants of field personnel. Frequent self-checks for
crawling ants should also be performed.
Mild insect stings and bites should be treated by applying a baking soda paste or ice wrapped in a
wet cloth. Do not pull out stingers with tweezers or fingers. Stingers should be gently scraped
from the skin, working from the side of the sting, using your fingernail, the edge of a credit card,
a dull knife blade, or other straightedge object.
Equine encephalitis, an inflammation of the brain, can be carried by mosquitoes. Symptoms
range from none to mild flu-like symptoms (fever, headache, sore throat) to rare infection of the
central nervous system with sudden fever and severe headaches followed quickly by seizures and
coma. In the more severe variety, the mortality rate is up to 60 percent, with permanent brain
damage in many of the survivors. Field personnel must wear long-sleeved clothing and/or use a
DEET (N,N-diethyl-meta-toluamide) containing insect repellent if they are working in areas of
mosquito infestations.
West Nile virus is spread by the bite of an infected mosquito, and can infect people, horses,
many types of birds, and some other animals. Most people who become infected with West Nile
virus will have either no symptoms or only mild ones. On rare occasions, West Nile virus
infection can result in a severe and sometimes fatal illness known as West Nile encephalitis (an
