Storage

In AIRLab, access to resources such as tools and materials is specified using a three-colour code.

Colour codes are green, orange and red.
Usually the code is specified on the container (e.g.: box, cabinet) where the resource is stored.

The colour code determines what a user must do before they can use the resource. (What they must do after use does not depend on colour.)

Special cases:

  • For nested containers with different codes, the colour of the innermost one prevails. (E.g.: the contents of a green box stored in an orange cabinet are green).
  • Resources which are not colour-coded should be considered as green.

What to do before use

Green resources: nothing.

Orange resources: ask your supervisor for permission to use the resource. Any means of communication (including speech) is OK, but you must get their (positive) answer before you can use the resource.

Red resources: arrange for your supervisor’s physical presence during your use of the resource. You cannot use it on your own.

What to do after use [all colours]

Put the resource back in its correct place. If you don’t know where such place is, ask. Never leave a resource lying around the lab: it’s your responsibility to find out what is its proper place, and to put it back there (even if you found it somewhere else!).

If the resource is a consumable, write an email to your supervisor specifying the remaining quantity of it.
Examples of consumables are: M5x20 screws; tin lead; masking tape; vynil glue; yellow LEDs; servo gears; Post-Its; lens caps; EEG electrodes; wood panels; cables; cloth; AAA batteries; black markers; saw blades; aluminium profiles; plastic sheets; cable shrink wrap; paint.
More generally: anything that reduces in quantity with use is a consumable.

If the resource is broken or malfunctioning, write an email to your supervisor describing the problem (photos often help). This also applies when you broke or damaged either the resource or anything else (it happens!). We need to know so we can repair or replace stuff.

Important!

If you see a resource that is damaged in a way that can cause harm to people (e.g.: broken shell which makes 230VAC parts reachable; damaged power cord; broken handle of a tool; bloated battery; power tool that makes an alarming noise) remove the resource from use, place it in a safe (hidden) place and tell your supervisor immediately.
