RISKS IDENTIFICATION

• Several cases we face most of the time
• Damage on the ground (offices, telecom rooms, )
• Manual work (machines, chassis weight, )
• Road risk (access track in altitude, road
  border)
• Electricity (near HV materials, TCM equipments )
• Outdoor work (insects, storm during work on PSTN
  connecting box)
• Optical fibber utilization (laser, skin
  penetration by fibber, )
• Falls from heights (line traps control, )
• Antenna (magnetic radiation, )
• Fire (by electricity, forest fire in period of
  drought near TCM installations, )

PREVENTIVE ACTIONS

• Enable accidents to be avoided
• Reference data for standardized protection
  equipments (gloves, goggles, )
• Documented procedures for preventative measures
• Trainings
• Operating methods and specific documented
  operating methods (delimited intervention area,
  work on TCM lead cables, )
• Single-use protection equipments
• Hearing protection
• Mandatory clearances for workers, level depending
  on work type

5
PTI CASE SPECIFIC TOOLS

• Lone worker protection system that are used for
  TCM works in RTE sites (Protection du Travailleur
  Isolé - substations, district control centers)
• Loss of verticality alarm system
• Dead-man detection system timer that need to
  be periodically manually activated otherwise
  alarm generation
