Exo – Gas Protection Helmet
Exo the gas protection helmet is designed for oil and gas
industry workers in order to provide them an enhanced
safety with increased comfort.

Exo – Gas Protection Helmet
“When it’s too much poisonous gas, you can’t smell it!” Hans Cray: Dräger Protection Solutions Manager
How does it feel?
We’ve been to Gothenburg Preemraff Gas Refinery, and tested all the safety equipment in the Employee Training Center.
Choosen Product Category
The safety and rescue equipment of Dräger Safety has bunch of products for application on the head of the workers. The products serve different type of benefits and features, but there is a missing point of optimization. Although, the number of products has the plus of variable usage, it has the lack of modularity.
Looking at the product range and their appearance I notice that they seem so individual. But wouldn’t it be good for workers if the protection equipment would be able to work together as a ‘team’?
To gain a true understanding of Dräger Safety as a brand, we spent a couple of days analyzing the products and the brand and tried to put them into clusters.
Color Material Finish
We divided the product categories with considering CMF, product features and specialties.
In this phase, we checked the current technologies, in development technologies, and the
upcoming technology predictions. Later on I prepared a matrix from today to future in
scale of relevant and inspirational technologies.
How Might We?
5 hours means 539 ideas to us! We asked the question “How Might We?” to bring up golden ideas for the problems we analyzed.
Accessibility of the Safety Equipment
During an emergency in a gas refinery, workers have some troubles to find the safety equipment during that chaotic situation.
The safety equipments are uncomfortable and inflexible which even causes injuries and illnesses.
Lack of Feedback
There is not enough feedback if a safety mask is sealed properly.
Lack of Visibility
Due to the thick equipment, workers have some visibility issues that affects their work and comfort.

Ergonomics & Proportions
I’ve studied ergonomics and proportions through a 1:1 clay model that I did some user test with later on the process.
Exploring more with 1:1 sketches to refine the form and proportions
Getting the right proportions as fast as possible for the CAID model.
exo – Gas Protection Helmet
Exo is connected to a Powered Air Purifying Respirator (PAPR) during the usage, providing safety
especially for the poisonous gas accidents in the gas refineries.
In Case of an Accident…
Integrated gas detector notifies the chemical gas in the environment and sends the signal for
the activation of the PAPR device.
It is located to be as close as to the head for critical situations, since different chemical gases have
various densities rather than air which doesn’t mostly diffuse homogeneously together.
Detection of the harmful chemicals around triggers the safety mode, and Exo immediately releases the Split-Visor© and fills the inner area with positive air pressure, so there wouldn’t be any other gases leaking inside the mask.
This feature eliminates the time consumed while trying to access the safety equipment in the gas refinery during an accident which may save lives.
Split Visor and Positive Air Pressure
Turning the safety mode on and releasing the split visor to avoid chemical gases don’t need any extra energy source than the air pressure itself from the PAPR device.
Air is directed through a conical form to increase it’s pressure until the air outlets are open and air overflows between the Split-Visor© and face of the gas refinery worker.
Due to the design of the Split-Visor©, there isn’t any safety equipment that might block the sight of the gas refinery worker while the safety mode on.
Safety During Critical Tasks
Safety mode can be turned on manually by pulling down the jaw part of the Split-Visor© which will trigger the PAPR device to start the air flow.
