The Emergency Bunker is a room located underneath the laboratory that is accessible in emergencies like the Isla Nublar incident.
The emergency bunker is roughly 10 ft below ground and can be accessed from the outside by the Holding Pen, or inside from the Control Room. It has:
- Shelves with maps of the park
- Cabinets stocked with SPAS-12 shotguns and ammunition
- Stone walls
- Iron Doors
- Emergency Lights
After one climbs some stairs, the outside is a concrete building, with iron doors to shield people inside from potential dinosaur attack. The door also has a small window.
The Emergency Bunker never appears in the novel, but is replaced by the Safari Lodge; the heavily armored hotel for Jurassic Park.
