- This method was useful on transmitters that were required to be silent between sentences to allow rebroadcast due to signals not being strong enough, and putting input on closed circuit and knowing the general emergency broadcast system to do so.
- Using closed circuit and advanced security systems was deemed necessary for the protection of staff members working in laboratory sections specifically designated as "safe"
- All staff members are safe through the emergency closed circuit process whose ultimate goal is to assist in securing safe perimeters around laboratory and research centers worldwide to deter and respond urgently and safely to future emergencies.
