GTR Regular Robustness Gas-Tight Suit

The GTR is a fully encapsulating, regular robustness gas-tight suit that protects emergency responders against toxic or corrosive gases, liquids and solid chemicals. It meets EN 943-2:2019 Type 1a-ET and is designed to be worn with self-contained breathing apparatus (SCBA) inside the suit. The GTR is available in two high-performance chemical barrier materials, DuPont™ Tychem® TK and Respirex Chemprotex™ X.

Both versions share the same design, features and EN 943-2:2019 Type 1a-ET certification, and both achieve breakthrough times of more than 480 minutes against all 15 chemicals in the EN 943-2 test battery. The main differences are in the material performance. Chemprotex™ X offers higher puncture resistance (Class 3) and tear resistance (Class 6), while the two materials perform differently against some individual chemicals. Comparing both against the substances you expect to encounter, using the permeation data on this page, is the best way to choose.

The GTR is worn with self-contained open-circuit compressed air breathing apparatus conforming to EN 137, which is fully enclosed inside the suit. An optional low pressure or high pressure pass-through allows a second cylinder or an airline to be connected to the breathing apparatus during decontamination, extending the time available to the wearer.

Yes. The GTR has bat-wing sleeves that allow the wearer to withdraw their hand from the glove and check gauges or other equipment inside the suit, such as the breathing apparatus pressure gauge. The large flexible visor also gives a wide field of view during operations.

Yes. A training version of the GTR is available, manufactured in green PVC and designed for repeated use with no testing required. It allows teams to practise donning, doffing and working in a gas-tight suit without using operational stock.
