There is razor wire woven in between the chain links as to deter SCP 5106-B from scaling send fence and a reinforced steel roof approximately 3 in thick going the whole length of the 2.1 kilometre long fence. The fence is constantly kept at 100 kilowatts of electricity personnel including D class personnel are not permitted to go within 2 metres because the consequences of touching the water could result in this person being given a job suitable for amputees.
