Every AlphaTec® gas-tight suit (formerly known as TRELLCHEM®) manufactured has a unique number, which makes it possible to trace when it was manufactured, as well as which materials and components were used. This number is called "Production number", "Batch number", "Serial number" or simply the "Suit number".
You will find the number on the Inner label glued inside the suit, in the back or in the hump.
On TRELLCHEM® branded suits you will find the number on the Inner label (NFPA 1991) or Inner label (CE).
