<br /> shoes or boots are also required. The shoes must be chemically resistant or protected with appropriately selected boots/coverings where
<br /> necessary. Unless otherwise specified,normal work clothes must be worn. Long sleeves and gloves are also required whenever necessary
<br /> to protect against hazardous contact,cuts,abrasions or other possible skin hazards.
<br /> ® Electrical. OSHA regulations require that employees who may be exposed to electrical equipment be trained to recognize the associated
<br /> hazards and the appropriate control methods. All extension cords used for portable tools or other equipment must be designed for hard or
<br /> extra usage and be(three-wire)grounded. All 120-volt,single-phase 15-and 20-ampere receptacle outlets on construction sites and other
<br /> locations where moisture/water contact may occur must be equipped with ground-fault circuit interrupters(GFCI)units. GFCI units
<br /> must be attached directly to or as close as possible to the receptacle. GFCI located away from the receptacle will not protect any wiring
<br /> between the receptacle and the GFCI unit. Only the wiring plugged into the GFCI and outward will be protected by the GFCI. All
<br /> (temporary lighting)lamps for general illumination must be protected from accidental breakage. Metal case sockets must be grounded.
<br /> Portable lighting in wet or conductive locations should be 12 volts or less.
<br /> ❑ Drums and Buried Drums. As a precautionary measure,personnel must assume that labeled and unlabeled drums encountered during
<br /> field activities contain hazardous materials until their contents can be confirmed and characterized. Personnel should recognize that drums
<br /> are frequently mislabeled,particularly drums that are reused.
<br /> Only trained and authorized personnel should be allowed to perform drum handling. Prior to any handling,drums must be visually inspected
<br /> to gain as much information as possible about their contents. Trained field personnel must look for signs of deterioration such as corrosion,
<br /> rust or leaks,and for signs that the drum is under pressure such as swelling or bulging. Drum-type and drumhead configuration may provide
<br /> the observer with information about the type of material inside(e.g.,a removable lid is designed to contain solids,while the presence of a
<br /> bung indicates liquid storage).
<br /> Although not usually anticipated,buried drums can be encountered when digging test pits. Therefore,the following provisions must be
<br /> observed if drums are encountered:Machine excavation(e.g.,backhoe)should cease immediately anytime a drum is encountered. The
<br /> appropriate management personnel should be notified immediately. All personnel should be instructed to immediately leave the work area.
<br /> Even authorized personnel must not enter an excavation where drums have been uncovered, even for monitoring purposes, unless all
<br /> provisions of OSHA's trenching and excavation standard have been met and the appropriate level of PPE is utilized. Sampling of unknown
<br /> drums usually requires Level B protection. Buried drums must not be moved unless it can be accomplished in a safe manner and overpack
<br /> drums are available.
<br /> ® Fire and Explosion. The possibility of flammable materials being encountered during field activities must be recognized and the
<br /> appropriate steps necessary to minimize fire and explosion must be observed. This includes situations where excessive organic vapors or
<br /> free product are encountered. When this occurs,monitoring with a combustible gas indicator(CGI)is required.
<br /> Excessive organic vapors,for the purposes of initiating the use of a CGI,are defined as sustained readings(i.e.,continuous for at least 5
<br /> minutes)at or above 250 units or as an instantaneous reading at or above 1,000 units on the PID or FID,in close proximity(within 1 foot
<br /> or less)of the borehole,test pit,sampling location,or other area of potential exposure.
<br /> In situations where hexane and/or methanol are needed for field activities,the following precautions must be observed: Keep flammable
<br /> and combustible materials away from heat,sparks and open flames;do not smoke around flammable or combustible materials;and keep all
<br /> flammable and combustible liquids in approved and properly labeled safety containers.
<br /> ❑ Landfill/Methane Hazards. Fire and explosion should be regarded as one of,if not the,most significant potential hazards associated with
<br /> drilling operations and other intrusive work conducted at a landfill. Accordingly,all sources of ignition must be fully controlled. Failure
<br /> to control ignition sources could result in fire,explosion,and pose a serious threat to life and health. Control methods may include forced
<br /> ventilation and/or filling the borehole with enough water to inhibit the release of methane and other gases that would otherwise escape
<br /> through the top of the borehole.
<br /> If forced(mechanical)ventilation is to be used,all such equipment must be approved for Class I,Division I hazardous atmospheres. The
<br /> blower must be positioned to blow across the top of the borehole so that gases and vapors may be diluted as they exit the borehole. Do not
<br /> attempt to suck out the gases or vapors. Blowers,all other mechanical equipment,and tools taht could release sparks or static electricity
<br /> must be bonded and grounded.
<br /> Regardless of the gas/vapor control method used,the atmosphere surrounding the borehole must be frequently monitored using direct
<br /> reading instruments approved for Class I,Division I hazardous atmospheres. Monitoring should be conducted within 1 to 2 feet of the top
<br /> of the borehole. Do not insert sampling devices into the borehole. Never approach the auger or drill shaft while it is in operation.
<br /> Regardless of actual instrument readings,if all sources of ignition cannot be controlled,operations should be immediately shut down and
<br /> the area evacuated if readings equal or exceed 10%of LEL until ignition sources have been eliminated. Ignition sources include,but are
<br /> not limited to,smoking,static electricity,lighting,open flames,spontaneously ignitable substances,frictional heat or sparks,hot surfaces,
<br /> radiant heat,electrical sparks,stray currents,cutting and welding,ovens,furnaces,and heating equipment.
<br /> ® Heat and Cold Stress. Overexposure to temperature extremes can represent significant risks to personnel if simple precautions are not
<br /> observed. Typical control measures designed to prevent heat stress include dressing properly,drinking plenty of the right fluids, and
<br /> establishing an appropriate work/break regimen. Typical control measures designed to prevent cold stress also include dressing properly,
<br /> and establishing an appropriate workibreak regimen.
