Each visitor is asked to answer a medical questionnaire before he or she is allowed to visit the Czech facility of Canadian EMS-provider Celestica in Ráječko. However, this is not something that is exclusive to the Czech facilities. A similar form awaits visitors to all of the Celestica's facilities around the globe.

This is said to be a precautions measure, as two of Celestica's facilities are located in Mexico: in Monterrey and in Reynosa.
