  • All ACT team members required to work on the site must consult their physicians to verify there are no medical conditions that make it inadvisable to work at high altitude.
  • ACT or the designated sponsoring institution shall pay for the medical exam.
  • It is each individual's responsibility to have the required medical exams performed before arrival to Chile. Everyone should consult their doctor annually.
