This variation on the standard spacesuit appeared in a number of Year 2 episodes. There seem to be just two suits.
They first appeared on technicians in The Exiles. The Swift in Brian The Brain has a silver spacesuit with orange back pack and re-detailed chest pack (although the neck ring is orange). Koenig wears the same suit and helmet in The Seance Spectre as an "Anti Radiation" suit. In Dorzak Helena and a medic wear the suits, without helmets or equipment, as "Anti Contamination" suits.
The Alphan firemen in Space Warp and The Bringers Of Wonder part 1 wear identical silver suits with fire hoods instead of helmets, and a fire extinguisher back pack.
The two suits were purchased by Group 3 for the film Into Infinity, filmed prior to Year 2.
Brian The Brain: the chest pack is essentially the same as the standard pack, with more graphics.
The backpack is a new orange design. It looks suspiciously like a plastic tray for draining dishes after washing up (and there's another one, in grey and upside down, on the wall).
The same backpack is seen outside the vacuum chamber in The Beta Cloud (the vacuum chamber was used for testing spacesuits).
And here it is again, in the Records Lab in Bringers Of Wonder part 1
Dorzak "anti contamination" suits. Helena carries a normal spacesuit helmet with orange neckring.
The Seance Spectre: a standard chest pack and back pack. The neck ring is silver, and the helmet and arm badge read "ANTI RADIATION".
The fire-fighters in Space Warp. The backpacks are numbered 6 and 7. These fire-fighters wear fire hoods, not astronaut helmets.
As do these fire-fighters, in The Bringers Of Wonder part 1 (although they enter from the lunar surface).
The Exiles: no insignia.
