Match the protection to the task rather than issuing one set for everything. Retrieving a cane from a vessel, decanting into an open dewar and filling a bulk vessel carry different splash risks, and staff will quietly stop wearing kit that is wrong for the job in front of them.

For routine handling and retrieval: loose fitting cryogenic gloves with a gauntlet cuff worn outside the sleeve, safety glasses, a laboratory coat and closed shoes. For decanting, filling or any operation where liquid is moving: add a full face shield over the glasses, and an apron where the transfer is above waist height.

The point about gloves is worth stating plainly, because it is the most common mistake. Cryogenic gloves are splash protection, not immersion protection. No laboratory glove is rated for putting a hand into liquid nitrogen, and a close fitting glove that traps liquid against the skin causes a worse injury than bare skin would, since liquid on skin largely boils off. Loose is the safety feature.

Two things belong with the PPE rather than after it: trousers worn over the top of boots so that splashes cannot run in, and a written instruction that anyone working alone in a store carries a personal oxygen monitor.
