A B777 captain advised he considers the elevated runway modifications to the east end of runway 10R/...

Narrative:

Fll runway 10R/28L; currently under construction and slated for completion in sept 2014; is an unsafe and dangerous design.with its approximately 60 foot high mse walls surrounding three sides of the east end of the runway and parallel taxiway; and more specifically the planned east end 600 ft emas bed; the design of runway 10R/28L makes it virtually impossible for passengers to safely evacuate and egress from an aircraft stopped in the emas.this untenable situation is further complicated in the event of an aircraft fire. As the prevailing winds at fll are generally out of the east/southeast; evacuating passengers would be trapped in the confined and elevated 'safety area.' the 60 ft high walls effectively prevent passengers and crew from distancing themselves from the disabled aircraft and responding arff equipment.the B777-200 configuration that my company currently utilizes is 289 passengers; 11 flight attendants; and 4 pilots. Given the extremely constrained east end emas area; as pilot in command; I will not takeoff from or land on runway 10R at fll. To do otherwise would be to jeopardize the safety and well being of my passengers and crew.
