The staff of Jurassic Park has uniforms and equipment.
Raincoats[]
Ellie in yellow raincoat
In Jurassic Park Ellie Sattler, Robert Muldoon, and Dennis Nedry wear yellow raincoats with the yellow/black Jurassic Park Logo on it. This raincoat design might be inspired by the yellow raincoat that Ed Regis wears in the chapter Prologue: The Bite of the Raptor of the Jurassic Park novel.
Security Uniforms[]
In the novels, it is implied that the uniform was similar to that of policemen. In the movies, however, the uniform is a blue jumpsuit with an orange helmet.
Veterinarian Uniforms[]
The vets' uniform is different shades of green (most likely for camouflage) with a green cap.
