🎯 Key Takeaways for quick navigation: Electron microscopes require lead shielding to absorb x-rays emitted by high-energy electrons. Cooling channels with water are essential for maintaining thermal equilibrium in electron microscopes. Microscopes are sensitive to temperature changes, even body heat from people entering the room. Water leaks from cooling channels and basement floods pose electrocution hazards. Electron microscopes can pose asphyxiation hazards due to leaks of odorless and colorless gases like sulfur hexafluoride. Liquid nitrogen used in cryo-EM can displace oxygen, leading to asphyxiation. Handling liquid nitrogen in cryo-EM poses risks of burns from exposure to cold surfaces. Climbing ladders or standing on desks to pour liquid nitrogen can lead to falls or injuries.
