Handling of Cleanroom Boots

• Boots in principle are worn over lab shoes; however, if users prefer, they may wear boots directly without shoes.
• Clean boots are available in the leftmost cabinet in the wardrobe/entrance.
• The team will take away boots for washing together with the overalls, but only for users with shared shoes.
• Users with personal shoes must themselves put the boots in the washing bins, in general the day before the overalls are changed (Wednesday evening).
• Sizes: ES up to size 36 for green (shared) shoes, S for 37/38, M for 39/40, L for 41/42/43, EL for 44 and larger. For white personal shoes, subtract about 2 sizes, i.e L is for sizes 43/44/45 approximately.

storage

• users with personal shoes: keep boots on shoes, store them in personal compartment
• users with shared shoes: keep boots attached to right leg of overall (see below)

putting on new pair of boots

1. take shoes as usual, proceed to change area and put them on
2. unpack boots, open buttons, zippers and buckles and place boots on floor, but keep everything on top of sole (not touching floor)
3. don overall, put shoes back on
4. slip into one boot, lifting textile part of boot
5. close zipper fully up
6. close and adjust buckle (tight around foot/shoe)
7. close top button (tight around leg, to prevent gliding down)
8. slip into second boot and proceed as with first one

see video clip for steps 4 to 8 — although you should wear gloves, not like the guy demonstrating it ^-^ but who did not actually enter the cleanroom
