Predicted risks and mitigation strategies

Risk	Mitigation strategy
Loss of power	Generator/UPS
CO2/special gas mix failure	Automatic gas changeover manifold; regulators
Liquid nitrogen storage tank emptying	Liquid nitrogen level alarms
	Regular measuring/top-up of tanks. Replacement at end of life span. Safety training is a must
Staff member injured	Low oxygen level and high CO2 alarms PPE
	Fire alarms/extinguishers
Break into laboratory	Security monitoring; security response; locks on liquid nitrogen tanks
Equipment failure	Alarm system; spare equipment; service/maintenance contracts; arrangements with competitors
IT virus/hacking – loss of data	Regular backups (stored offsite); antivirus software

PPE=Personal protective equipment, UPS=Uninterruptible power supply
