5. EXECUTION OF BLASTING

5.1 On the day of the blasting activity, the CONTRACTOR's shot firer(s) will
obtain the needed explosive material and transport it to the WORK Site. The
CONTRACTOR's lead shot firer shall be in charge of all operations present
in the blasting area. He and the Company Representative shall ensure the
hot work permit is authorized prior to commencing WORK. Only then can
the unloading of the explosives from the truck take place. The unloading and
priming of explosives in the holes, as well as stemming, shall be performed
under the supervision of the CONTRACTOR's lead shot firer. The laying or
placing of delays and tying in of the shot shall be performed by the
CONTRACTOR's shot firer or one of his designated and qualified assistants.
The placement of covering material shall be supervised by the
CONTRACTOR's lead shot firer and completed to his and Company
Representative's satisfaction.

5.2 At the time, approximately fifteen (15) minutes prior to the shot, there shall
be one long siren signal. At this time, all personnel in the vicinity of the shot
must begin clearing out. At approximately five (5) minutes prior to the blast,
a series of long siren signals shall be given to warn all to stay clear. By this
time, CONTRACTOR shall have posted guards at a safe distance from the
shot with warning flags, and deny all except the CONTRACTOR's shot firer,
access to the blast area. One last warning will be sounded by a series of
short-siren signals when the CONTRACTOR's Shot Firer has assured
himself everyone is clear and the shot is ready for detonation. After the
detonation, an all-clear signal consisting of two (2) long signals using the
siren shall be sounded. This shall be given only when the CONTRACTOR's
lead shot firer has assured himself it is safe to return to the shot area.

5.3 Cancellation of Blast

Should the shot crew find it impossible to shoot for any reason, the
appropriate form, Cancellation of Blast AB-0020, must be executed and
acknowledged by the signature of appropriate project personnel and the
CONTRACTOR's lead shot firer.

2.2.7.1 The ability for the equipment operator to view the area
behind the equipment to a distance of at least ten (10)
meters.

2.2.7.2 A minimum of four color camera inputs to a color display

for the equipment operator which shall be of minimum 7”
diagonal screen size, with the capability of monitoring all
cameras simultaneously on the same display with
adequate resolution and color rendition to allow the easy
visual identification of hazards around the vehicle.

2.2.7.3 The ability to operate effectively in low light environments

(illumination greater than or equal to 5 foot-candles or 54

document that all Proximity Warning System Equipment installed on
earthmoving and construction equipment is operating correctly at
the beginning of each day.

2.3.3 CONTRACTOR shall ensure that for all equipment on the Job,
Laydown, and Fabrication Sites, the PWAS alert threshold detection

personnel without correctly operating Proximity Warning System
Equipment shall not be permitted to access or perform work at the
Job, Laydown, and Fabrication Sites.

2.3.5 CONTRACTOR shall ensure that all equipment operators shall be

provided with training on the purpose, use, and maintenance of
PWAS and RVCCCS prior to operating any equipment with the
system installed, and the administration of such training shall be
documented in the project safety records.

2.4 Normal and Incident Trend Reporting and Investigation Requirements

The Proximity Warning System Coordinator shall conduct weekly, and

monthly trend reporting of any incidents, including “near misses,” that either
activate proximity alarms or should reasonably have activated such alarms
shall be investigated and such investigation shall document the status of
installation, use, operation, maintenance, and effectiveness of the Proximity
Warning System Equipment, including any data recorded by Data Logger
equipment if available.
