The bio-hazard symbol was created by the DOW chemical company in 1966 as a universal label for their hazardous products, and became the universal symbol of biological hazards in 1967 and is commonly used in the medical field. It was chosen because of its memorability, lack of meaning, universally accepted, symmetrical and easy to draw. It is seen in use in Jurassic Park as a label for the laboratory door as well as the numerous toxic substances used in the cloning process at Jurassic Park.
