![]() ![]() If there is a risk of a splash, a face shield may be required. When refilling dewars or otherwise working with cryogens, safety goggles, lab coat and cryo gloves are required. Because samples are sealed, PPE – gloves, goggles, and lab coats are not required. Long pants (covered legs) and proper footwear (covered feet) is the minimum attire required to access the NMR facility. Proper laboratory attire is required in the NMR facility. It’s extremely important to pay close attention to the Gauss lines and to remove any magnetic materials from your person before accessing the magnet. ![]() Magnetic field (Gauss) are marked and blocked around the magnet, showing the areas where magnetic materials are not permitted. There are no areas in the NMR facility appropriate for sample prep. All samples must be prepared outside of the NMR facility in the research lab and must be properly sealed before entering the facility. Chemical hazards are minimized by the use of small samples in sealed tubes. The major hazards in the NMR facility are the strong magnetic fields around the magnets and the use of liquid cryogens – liquid nitrogen and liquid helium. ![]()
