establishing an appropriate work/break regimen. Typical control measures designed to prevent cold stress also include dressing property,
<br /> and establishing an appropriate work/break regimen.
<br /> ❑ Moving Vehicles,Tragic Safety. All vehicular traffic routes that could impact worker safety must be identified and communicated.
<br /> Whenever necessary,barriers or other methods must be established to prevent injury from moving vehicles. This is particularly important
<br /> when field activities are conducted in parking lots,driveways,ramps or roadways. OSHA 1926.201 specifies that when signs,signals or
<br /> barricades do not provide adequate protection from highway or street traffic,flagmen must be utilized. Flagmen must wear red or orange
<br /> garments. Garments worn at night must be reflective.
<br /> ® Noise. Noise exposure can be affected by many factors including the number and types of noise sources(continuous vs. intermittent or
<br /> impact)and the proximity to noise intensifying structures(e.g.,walls or buildings)that cause noise to bounce back or echo. The single
<br /> most important factor effecting total noise exposure is distance from the source. The closer one is to the source,the louder the noise. The
<br /> operation of a drill rig,backhoe,or other mechanical equipment can be sources of significant noise exposure. In order to reduce the
<br /> exposure to this noise,personnel working in areas of excessive noise must use hearing protectors(e.g.,can plugs,ear muffs).
<br /> Rule-of-Thumb: Wherever actual data from sound level meters or noise dosimeters is unavailable and it is necessary to raise one's voice
<br /> above a normal conversational level to communicate with others within 3 to 5 feet away,hearing protection should be wom.
<br /> ❑ Overhead Utilities and Hazards. Overhead hazards can include low hanging structures that can cause injury due to bumping into them.
<br /> Other overhead hazards include falling objects, suspended loads, swinging loads, and rotating equipment. Hardhats must be worn by
<br /> personnel in areas were these types of physical hazards may be encountered. Barriers or other methods must also be used to exclude
<br /> personnel from these areas where appropriate. Electrical wires are another significant overhead hazard. According to OSHA(29 CFR
<br /> 1926.550),the minimum clearance that must be maintained from overhead electrical wires is 10 feet from an electrical source rated<50
<br /> kV. Sources rated >50 kV require a minimum clearance of 10 feet plus 0.4 inch per kV above 50 kV.
<br /> ® Pedestrian Traffic. The uncontrolled presence of pedestrians on a drilling or excavation site can be hazardous to both pedestrians and
<br /> site workers. Prior to the initiation of site activities,the site should be surveyed to determine if, when,and where pedestrian may gain
<br /> access. This includes walkways,parking lots,gates, and doorways. Barriers or caution tape should be used to exclude all pedestrian
<br /> traffic. Exclusion of pedestrian traffic is intended to prevent injury to the pedestrians and eliminate distractions that could cause injury to
<br /> Partner personnel or other site workers.
<br /> ❑ Test Pit and/or other Excavations. All provisions of the OSHA trenching and excavation standard(29 CFR 1926.650-652)must be
<br /> followed during excavation activities. This includes all test pit excavation and sampling activities. The estimated location of utility
<br /> installations such as sewer,telephone,electric, water lines,and other underground installations that may reasonably be expected to be
<br /> encountered during excavation work,must be determined prior to opening an excavation.
<br /> Excavations in contaminated or potentially contaminated areas must be tested for confined spaces atmospheric hazards prior to entry.
<br /> Excavations should not be entered if other means me available to perform the task requiring entry. If entry into an excavation is required,
<br /> the atmosphere within the space must be monitored by a trained person to assure that oxygen concentrations are at greater than or equal to
<br /> 19.5 percent, that combustible gas levels are less than 10 percent, and that vapor levels are within applicable safe exposure(PEL and
<br /> TLV)limits.
<br /> A ladder or similar means of egress must be located in excavations greater than 4 feet in depth so as to require no more than 25 feet of
<br /> lateral travel for employees. No person should be allowed to enter an excavation greater than 5 feet in depth unless the walls of the
<br /> excavation have been protected using an approved shield(trench box),an approved shoring system,or the walls have been sloped back an
<br /> appropriate angle,the excavation is free of accumulated water,and the excavation has been tested for hazardous atmospheres as noted
<br /> previously. If personnel enter an excavation,the spoils pile and all materials must be placed at least 2 feet from the edge of the excavation
<br /> to prevent the materials from rolling into the excavation. Personnel must remain at least 2 feet away from the edge of the excavation at all
<br /> times. Upon completion of a test pit exploration,the excavation should be backfilled and graded. Excavations should never be left open
<br /> unless absolutely necessary,and then only with proper barricading and controls to prevent accidental injury.
<br /> ® Underground Utilities and Hazards. The identification of underground storage tanks(USTs),pipes, utilities,and other underground
<br /> hazards is critically important prior to all drilling,excavating and other intrusive activities. In accordance with OSHA 29 CFR 1926.650,
<br /> the estimated location of utility installations,such as sewer,telephone,electric,water lines and other underground installations that may
<br /> reasonably be expected to be encountered during excavation work, must be determined prior to opening an excavation. The same
<br /> requirements apply to drilling operations and the use of soil-gas probes. Where public utilities may exist,the utility agencies or operators
<br /> must be contacted directly or through a utility-sponsored service such as Dig-Safe. Where other underground hazards may exist,
<br /> reasonable attempts most be made to identify their locations as well. Failure to identify underground hazards can lead to fire,explosion,
<br /> flooding,electrocution,or other life threatening accidents.
<br /> ❑ Water Hazards and Boat Sampling. The collection of water or sediment samples on or immediately adjacent to a body of water can
<br /> pose significant hazards. In addition to the slip,trip,and fall hazards associated with wet surfaces,the potential for drowning accidents
<br /> must be recognized. These hazards can be intensified by the use of some PPE,particularly if respiratory protection is worn. OSHA 29
<br /> CFR 1926.106 requires that all employees working over or near water, where the danger of drowning exists, must wear a U.S. Coast
<br /> Guard-approved lifejacket or buoyant work vest. Ring buoys and emergency standby personnel must also be in place.
