    small-quantity exemption rules apply).

59
Module 6 Chemicals
  • Check your States laws on intrastate transport
    of small quantities of chemicals in a government
    vehicle.
  • It is not necessary to placard your vehicle when
    transporting small quantities of chemicals.
    Placarding a vehicle informs enforcement and
    emergency response personnel that the vehicle
    contains large amounts of the placarded material.
  • First-response teams might not immediately
    approach a wrecked vehicle that is placarded for
    a highly dangerous or reactive material.

60
Module 6 Chemicals
  • For safe containment and transport of chemicals
  • Protect yourself and passengers in the vehicle by
    stowing and securing chemicals away from the

    vertical position.
  • Never transport cylinders with regulators
    attached or with safety caps missing.
  • When possible, transport chemicals in their
    original DOT-approved shipping containers with
    the package correctly sealed.

61
Module 6 Chemicals
  • Carry spill kit(s) appropriate for the chemicals
    being transported.
  • Label packages as to their contents, and remove
    old, inappropriate labels from containers that
    are being reused.
  • Keep a chemical inventory list in the glove box
    or side door pocket of the vehicle.
  • Waste products should be transported in the same
    safe and approved manner as other hazardous
    materials.

62
Module 6 Chemicals
  • Storage and Disposal
  • Chemicals require strict storage procedures for
    safety reasons.
  • Specific storage areas should be designated in
    your vehicle and office laboratory.
  • Use approved chemical storage cabinets.
  • Separate storage is needed for acids, corrosives,
    and flammables.
  • High purity, laboratory-grade flammables should
    be stored apart from other flammables, such as
    gasoline and solvents.

63
Module 6 Chemicals
  • Chemical and waste disposal requirements, and
    exemptions, are regulated by EPA and supplemental
    state guidelines must also be followedcontact

    safety issues associated with sampling or contact
    with contaminated water during field activities

65
Module 7 Contaminated
water
  • Contaminated Water
  • Communicate known or suspected contamination to
    all personnel who could come in contact with the
    sample or source water.
  • Never drink sample water, no matter how pristine
    the environment appears. For example, a clear
    mountain stream or lake may contain Giardia
    bacteria from beavers.

66
Module 7 Contaminated
water
  • Waterborne, disease-causing organisms (pathogens)
    are found in nearly all surface-water systems
    and occur in many ground-water systems.
  • Most pathogens generally originate from body
    fluids and feces of animals and humans, although
    some (Legionella, Pseudomonas aerogenosa,
    Clostridia spp.) are normal environmental
    inhabitants.

67
Module 7 Contaminated
water
  • Pathogens enter surface-water resources through
    sewage discharge and spills, animal feedlot
    operations, landfills, storm and agricultural
    runoff and direct contact.
  • Microorganisms also are transported on small
    particles such as dust or aerosols.
  • Pathogens enter ground water through infiltration
    from septic tank effluent, leachate from fields
    and ponds, and from faulty well seals and
    casings.
  • Bacteria, viruses, and other pathogenic organisms
    can occur in the most pristine environments.

68
Module 7 Contaminated
water
  • To minimize exposures to and effects from
    contaminated water
  • Receive required periodic (where appropriate)
    inoculations for waterborne pathogens (typhoid,
    tetanus, hepatitis, polio, and rabies).
  • USGS immunization program requires inoculations
    for field personnel working around polluted
    water.

69
Module 7 Contaminated
water
  • Contact the BRRCR Administrative Officer, BRRCR
    Assistant Branch Chief, or your Supervisor about
    receiving inoculations before you sample.
  • Wear rubber boots, coveralls or aprons, latex or
    vinyl gloves, and splash protection. (Note The
    proper way to dispose of contaminated gloves is
    to first turn the gloves inside out while taking
    them off.)

70
Module 7 Contaminated
water
  • Use personal protective equipment, possibly
    including respiratory equipment (certification
    required) when working in contaminated areas.
  • Pathogens can enter your body through many
    opening such as your mouth, eyes, nose, cuts,
    scrapes, or chapped skin.

71
Module 7 Contaminated
water
  • Avoid practices (such as mouth pipeting and
    unnecessary handling of sharps) that may allow
    ingestion of pathogens or other contaminants.
  • Never eat, drink or put items in your mouth while
    sampling.
  • Do not store food or drink in sample coolers.
  • Carry antibacterial soap and wash your hands
    before leaving site and wash again after
    unloading supplies.

72
Module 7 Contaminated
water
  • Disinfect all contaminated surfaces as soon as
    possible and handle bacteria plates carefully and
    autoclave them before disposal.
  • Alert colleagues and laboratory if samples could
    contain large concentrations of hazardous
    materials.
  • Contagious/hazardous biological material should
    be labeled with biohazard stickers.

73
Module 8 Environmental
conditions
  • Module 8 OBJECTIVE To address topics related to
    safety issues associated with exposure to extreme
    environmental conditions during field activities

74
Module 8 Environmental
conditions
  • Temperature and Sun Exposure
  • Prepare for extreme conditions that might be
    experienced in your area.
  • Before leaving for the field, check the weather
    forecast.
  • Comfort range for humans is between 60 to 90
    degrees Fhypothermia and hyperthermia can occur
    in temperatures outside this range

75
Module 8 Environmental
conditions
  • Hypothermia is a condition of reduced body
    temperature caused by exposure to cold, and
    aggravated by wet clothes, wind, hunger, and
    exhaustion

76
Module 8 Environmental
conditions
  • Warning signals of hypothermia are uncontrollable
    shivering, incoherence, listlessness, fumbling
    hands, frequent stumbling, drowsiness, inability
    to get up after resting.
  • Victims should be moved to a sheltered area,
    remove/replace wet clothes, and provide external
    warmth if possible.

77
Module 8 Environmental
conditions
  • Hyperthermia is a condition of increased body
    temperature caused by exposure to excessive heat.
  • Warning signals of hyperthermia are throbbing
    pressure in the head, unsteadiness, dizziness,
    nausea, dry skin, rapid pulse, and muscle pains
    and spasms.
  • Treat immediatelyfirst aid involves cooling down
    and rehydrating.

78
Module 8 Environmental
conditions
  • to prevent hyperthermia
  • Drink water in moderate amounts on a scheduled
    basis.
  • The normal body requirement for fluids in
    temperate regions is 2 1/2 quarts per day desert
    conditions require more fluid.
  • Avoid alcohol and caffeine (diuretics).
  • Wear lightweight clothing and wide-brimmed hat.
  • Schedule activities that require the most
    exertion in early morning or late afternoon.

79
Module 8 Environmental
conditions
  • Sun exposure can have painful and dangerous
    short-term and long-term effects.
  • To prevent excessive sun exposure wear a
    broad-brimmed hat, lightweight clothing, and
    apply sunscreen to all exposed skin to avoid
    burning and skin cancer.
  • Wear sunglasses with polarized lenses to protect
    eyes, reduce glare, and improve vision,
    especially when working on water or snow.

80
Module 8 Environmental
conditions
  • Thunderstorms and Tornadoes
  • Thunderstorms are often accompanied by high
    winds, lighting, and hail, are often predicted by
    weather forecasts - but also can move into an
    area with almost no warning. Afternoon summer
    thunderstorms are quite common in the Colorado
    Front Range.

81
Module 8 Environmental
conditions
  • To protect yourself during thunderstorms seek
    shelter inside a vehicle or building.
  • Keep away from open doors and windows, plugged in
    appliances, and metal.
  • In case of a lightning strike, someone must be
    able to begin revival techniques, such as CPR.
  • Put on rubber boots or rubber-soled shoes.
  • Do not work on electrical lines, pipes,
    cableways, or steel structures.
  • Do not use metal objects such as wading rods,
    bridge cranes, and well-logging equipment.

82
Module 8 Environmental
conditions
  • If caught in the open, crouch down low, but do
    not lie flat on the ground.
  • Avoid standing near isolated trees.
  • Avoid working on streams and lakes.
  • Seek lower elevations such as valleys or
    canyonsavoid being on peak or ridges.
  • If you feel your hair standing on end and your
    skin tingling, this is a sign that lightning
    might be about to strikecrouch immediately (feet
    together, hand on knees).

83
Module 8 Environmental
conditions
  • Tornadoes sometimes accompany thunderstormsthey
    are rapidly rotating columns of air that descend
    from the clouds in a funnel formation.
  • Tornados occur fairly often in the high plains
    area east of the Denver Front Range foothills.
  • Micro-burst downdrafts are localized high-wind
    phenomena in mountainous areas that can have much
    the same effect as a tornado.

84
Module 8 Environmental
conditions
  • To protect yourself during a tornado seek shelter
    immediately if there is a sudden, violent change
    in weather involving wind, rain, hail, or
    funnel-shaped clouds.
  • Avoid occupying vehicles or mobile homes.
  • If caught outside, find a ravine, ditch, or
    culvert and lie flat (but watch out for flash
    floods).
  • If inside, go to basement or lowest interior
    reinforced part of the structure (closet or
    bathroom) stay away from windows.

85
Module 8 Environmental
conditions
  • Floods
  • Rain can fall at a rate of several inches per
    hour and rapidly create dangerous flash flood
    conditions especially in the narrow canyons of
    the Front Range foothills such as Bear Creek,
    Boulder Creek, and Clear Creek.

86
Module 8 Environmental
conditions
  • Weather forecasts are helpful in planning your
    activities, but be aware of changing conditions.
  • Be aware of dry creekbeds that can become raging
    rivers in a short period (plan your escape ahead
    of time so you can act immediately).

87
Module 8 Environmental
conditions
  • Earthquakes, Landslides, and Rockfalls
  • Although earthquakes occur more frequently in
    tectonically active areas, an earthquake can
    occur anywhere and without warning.

88
Module 8 Environmental
conditions
  • The greatest danger in an earthquake is from
    falling objects and collapsing buildings.
  • Take cover under a solid structure able to
    withstand impacts from above.
  • If you are driving, slow down and pull over to
    the side of the road.
  • Avoid overhead structures such as bridges and
    signs.

89
Module 8 Environmental
conditions
  • Landslides and Rock falls Small roadside
    landslides and small to large rockfalls are
    common along roads in mountainous areas of
    Colorado. Fatal rockfalls have occurred along
    I-70 near Georgetown and along Highway 6 in Clear
    Creek Canyon near Golden. I-70 through Glenwood
    Canyon has been closed due to large boulder falls
    onto the highway. These events typically occur
    during or follow periods of heavy rain. Be aware
    of small rocks fallen onto the roadway they may
    be indicators of larger things to come! Take the
    Falling Rocks warning sign along a highway
    seriously.

90
Module 8 Environmental
conditions
  • Fire Forest fires are a common occurrence in
    Colorado and the Rocky Mountain region.
  • Fire can spread out of control rapidlycall 911
    if you notice a brush or forest fire, or if your
    own fire gets out of control.
  • Be aware of, and comply with, any burning bans in
    effect for your field site.
  • Take care to properly extinguish any burning
    materials and dispose of safely.
  • Remember You can help prevent Forest Fires!

91
Module 8 Environmental
conditions
  • Snow and Ice
  • Snow and ice are dynamic mediums that change
    quickly in structure and strength.
  • Snow and ice can accumulate rapidly, hiding
    hazards, and creating slippery conditions.
  • Heavy snowfall (white-outs) can be disorienting
    and can produce avalanche conditions in steep
    terrain.

92
Module 8 Environmental
conditions
  • Wear layers of appropriate clothing and work in
    teams.
  • Working on ice requires experience, training and
    knowledge of the water body over which the ice
    has formed. If possible, engage or consult
    personnel familiar with such work.
  • When in Doubt, Dont Go Out (on the ice).

93
Module 9 Animals
  • Module 9 OBJECTIVE To address topics related to
    safety issues associated with animal hazards
    during field activities
  • For guidelines on potentially dangerous animals,
    see web site
  • http//water.usgs.gov/owq/FieldManual/Chap9/A9.9.
    html
  • Before a field trip, find out which species
    inhabit the area and how to deal with them.
  • Most animals will vigorously protect their young
    and should not be approached or disturbed.

94
Module 9 Animals
  • Arachnids and Insects
  • Most common remedy for bites and stings involves
    basic first aid, followed by professional medical
    attention if symptoms warrant.
  • Persons with known allergic reactions to insects
    should wear or carry on their person medical
    alert identification, and carry sting kits for
    use in emergencies.

95
Module 9 Animals
  • Scorpions, spiders, and ticks
  • Spiders, and ticks are commonly found in Colorado
    and Rocky Mountain area.
  • Spiders and scorpions are known to inhabit
    enclosed, dark spaces, for example - inside well
    houses and streamgage shelters.

96
Module 9 Animals
  • Scorpions are known to frequent the desert, but
    are also found in more temperate areas.
  • They often blend in with the terrain.
  • Stings often involve an encounter between a big
    toe and a scorpion that has crawled into a shoe.
  • Check shoes and boots left in the field vehicle
    before putting them on.
  • Beware of putting your hands and feet into small,
    dark spaces.

97
Module 9 Animals
  • Only a few spiders in North America bite people,
    and the venom of most is harmless - exceptions
    include the black widow and the brown recluse.
  • Black widow spider is common in Colorado often
    found in wood piles and basement areas.
  • Brown Recluse spiders are found in much of
    Colorado their bite can be serious.

98
Module 9 Animals
  • Brown recluse spider (Loxosceles reclusa)
    frequents areas of human habitation and prefers
    dark spaces, such as equipment shelters, as well
    as areas in the wild.
  • Be familiar with the area in which you are
    working and take care when walking and when
    reaching into small spaces.
  • See web site showing picture of spiders
  • http//water.usgs.gov/owq/FieldManual/Chap9/A9.9.

99
Module 9 Animals
  • Ticks are found nearly everywhere in North
    America.
  • Transmitted diseases include Rocky Mountain
    spotted fever and Lyme disease.
  • To reduce exposure, wear long pants, tuck the
    pant legs into your socks.
  • Use a repellant containing DEET
    (N-diethyl-meta-toluamide).
  • Check regularly for ticks - including neck,
    scalp, and groin areas.

100
Module 9 Animals
  • Bees and Wasps
  • Bee stingers are equipped with barbs that should
    be scraped off if a person is stung--using
    forceps or tweezers to pull the stinger out can
    force more venom into the wound.
  • Wasp stingers has no barb the venom is injected
    and the stinger usually slides out.
  • Seek medical attention if symptoms warrant.

101
Module 9 Animals
  • Snakes
  • Only 10 percent of the approximately 3,000
    species in the world are poisonous.
  • In the event of snakebite, take victim to nearest
    medical facility as soon as possible.
  • Even if a person has been bitten by a
    nonpoisonous snake it should be treated by
    medical personnel (some people are allergic to
    the foreign protein in snake saliva).

102
Module 9 Animals
  • Common symptoms of poisonous snakebites from pit
    vipers are
  • burning, fiery, stinging pain at the bite site
  • swelling skin discoloration nausea and
    vomiting a minty, metallic, rubbery taste in the
    mouth sweating and chills
  • If pain does not get any worse and remains
    localized, venom probably was not passed.
  • If the pain becomes severe, venom was probably
    injected.

103
Module 9 Animals
  • Common poisonous snakes are copperheads,
    cottonmouths, water moccasins, coral snakes and
    rattlesnakes.
  • See web site showing picture of poisonous snakes

104
Module 9 Animals
  • Bears
  • Bear behavior is unpredictableaccording to
    Guidelines for Safe Geologic Field Work in Alaska
    (U.S.G.S, May 1978). Bears fiercely defend any
    carcasses and will often bury or partially cover
    such prizes for later.
  • Bears can see almost as well as people, but trust
    their noses much more than their eyes or ears.
  • Make frequent noise when traveling along trails
    that bears might use.

105
Module 9 Animals
  • Avoid carrion (dead and decaying animals or
    fish), fresh kill, or gut piles.
  • Avoid berry patches, or other areas abundant with
    plants that bears use for food.
  • Avoid willow and tall grass patches bears
    sometimes use these area for daybeds.

106
Module 9 Animals
  • Avoid areas with fresh bear tracks.
  • Make noise or wear bells when moving so as not to
    surprise bears.
  • Work in teams of two or larger.
  • If you find yourself close to a bear, give the
    bear all the room you can.
  • Let the bear know you are humantalk in a normal
    voice and wave your arms.

107
Module 9 Animals
  • DO NOT RUN! Bears will often make bluff charges
    without making contact.
  • If a bear actually makes contact, surrender! Fall
    to ground, curl up into a ball, and play dead.
    Typically a bear will break off its attack once
    it feels the threat has been eliminated.
    However, if a BLACK Bear continues to attack,
    FIGHT BACK.

108
Module 9 Animals
  • Mountain Lions
  • Mountain lions are a species of large cats found
    in the North Americaprimary habitat is within
    and west of the Rocky Mountains. Mountain Lions
    have been increasingly encountered in the Front
    Range foothills area of Colorado west of Denver.

109
Module 9 Animals
  • They are active during the day and night
    searching for food such as deer and smaller
    animals.
  • Be alert to reports of mountain lion attacks or
    sightings in your field site area.
  • Turning and running can evoke a predatory attack
    response.
  • Try to appear as large as possible raise your
    hands above your head holding a coat or other
    object.

110
Module 9 Animals
  • Rodents and other Small Mammals
  • Rodents and other small mammals can be disease
    carriers.
  • Known carriers of Hantavirus include the deer
    mouse, pinon mouse, brush mouse, cotton rat, and
    western chipmunk.
  • Hantavirus does not cause apparent illness in the
    host, but infected individual sheds the virus in
    saliva, urine, and feces for weeks.

111
Module 9 Animals
  • Rabies infection is another hazard of contact
    with small animals, especially skinks, raccoons,
    foxes, coyotes, bats, cats and dogs.
  • Structures with heavy rodent infestation should
    be approached with extreme caution and may
    require special decontamination procedures by
    trained safety personnel.
  • Do not attempt to remove or decontaminate a
    rodent infested area without first being trained
    in specific procedures and Do Not enter an
    infested area with such decontamination done
    first!

112
Module 9 Animals
  • Domestic Animals
  • Field work may involve working in areas where
    cats, dogs, cows, horses, and other animals can
    be carriers of disease.
  • Do not pet, feed, or have contact with these
    animals.
  • Before entering private property, obtain
    permission to enter.
