SLD45I91-204 addresses launch risk forecasts, employee education, launch notifications, toxic shelters, and on-base risk mitigation. It requires training, shelter procedures, hazard announcements, and continuing evaluation of launch conditions.

Applies to: This instruction establishes procedures to ensure that all CCSFS personnel and visitors can be protected from launch hazards resulting from any vehicle launched from either CCSFS or KSC.

Topics covered

  • Toxic dispersion hazards
  • Distant focusing overpressure
  • Inert and explosive debris
  • Launch risk forecasts
  • Employee education
  • Launch toxic shelters
  • Aural warning announcements

Questions and answers

What launch hazards must personnel be protected from?

All personnel must be protected from toxic dispersion, distant focusing overpressure (DFO), and inert/explosive debris (hereafter termed “launch hazards”) during launches, landings, and static fires (hereafter termed “launch”) from Cape Canaveral Space Force Station (CCSFS) and/or Kennedy Space Center (KSC). (paragraph 1)

What must supervisors do after an employee receives launch hazard training?

Once a new employee has received training, the supervisor will document this training in the employee’s personnel records. (paragraph 3)

When are scheduled launch announcements broadcast?

Cape Support will broadcast Message 1 (Attachment 2) via the Cape Aural Warning System (CAWS) every 4 hours (i.e., twice per shift) starting 2 days prior to the scheduled launch, or later if the launch date is still classified at that time. (paragraph 3)

Do unoccupied shelters have to open during non-duty hours?

During non-duty hours, shelters that would normally be unoccupied during the launch period need not be opened merely for shelter purposes and the Facility Manager or representative is not considered launch essential. (paragraph 91-710)

What determines launch shelter activation?

Shelter activation will be based on T-0 forecasted and real-time meteorological data along with SLD 45/SE physics models. (paragraph 91-710)
