at least one other worker. During initial site entry, it may be appropriate to utilize a "buddy
system" in which additional workers are assigned to provide safety backup.
The Field Team Leader, who is responsible for enforcing the "buddy system", should implement
the system at the Access Control Point for workers entering the Exclusion Zone.
As part of the buddy system, workers should remain in close proximity and maintain visual
contact with each other to provide assistance in the event of an emergency. Should an
emergency situation arise, workers should use prearranged communication signals agreed upon
prior to entering the contaminated area. The responsibilities of workers utilizing the buddy
Providing his or her partner with assistance,
Observing his or her partner for signs of chemical or heat exposure,
Periodically checking the integrity of his or her partner's PPE, and
Notifying the Project Manager or other site personnel if emergency assistance is needed.
Workers should not rely entirely on the "buddy system" to ensure that help will be provided in
the event of an emergency. To augment this system, workers in contaminated areas should
remain in line-of-sight or direct communication contact with the command post or Field Team
Leader at all times.
9.5. COMMUNICATION NETWORK AND PROCEDURES
Communication systems should be established for both internal and external communication.
Internal communication refers to communication among workers operating in the Exclusion
Zone or Contamination Reduction Zone, or between the Command Post and those workers.
Routine checking for proper operation should be addressed.
An internal communication system may be established using standard communication devices
such as radio, noisemakers, or visual signals. Verbal communication can be difficult as a result
of onsite background noise and the use of PPE. Therefore, pre-arranged commands and audio or
visual cues should be developed prior to entering the Exclusion Zone. A secondary set of non-
verbal signals should be established for use when communication devices fail or when
emergency situations occur.
External communication refers to communication between onsite and offsite personnel. An
external communication system should be maintained in order to:
Coordinate emergency response efforts with offsite responders,
Report progress or problems to management, and
Maintain contact with essential offsite personnel.
