Our Confined Space Training units are designed to accurately duplicate the obstacles or challenges discovered within the many confined space scenarios in the real world. Our simulators eliminate the need to rent spaces out of service or search for places to have realistic training scenarios; everything your team needs for a successful training program can be found in the unit. Safety and training are the top priorities in our designs so trainees in our simulators can endure mistakes without the risk of injury!

What is a confined space?

A confined space is any space that is not intended for continuous human occupancy and has limited or restricted means for entry or exit. Many workplaces contain areas that are considered “confined spaces” because while they are not necessarily designed for people, they are large enough for workers to enter and perform certain jobs. Confined spaces include, but are not limited to, tanks, vessels, silos, storage bins, hoppers, vaults, pits, manholes, tunnels, equipment housings, ductwork, pipelines, etc.

What is a Containerized Confined Space Simulator?

Our confined space training containers are mobile training units that allow for realistic and immersive confined space training. Our containers are specially designed to simulate real-life confined space environments. They can be used to teach workers about the dangers of confined spaces and how to safely enter, exit, and perform tasks within them. Confined space training units can be customized to suit any level of experience and can be delivered on-site.

Our Confined Space Simulator Expertise:

Our confined space simulators are affordable, mobile, can be built & delivered quickly, and help firms offer a safe space to train their employees. Safety and training is critical and we help firms with a straightforward solution to address a dangerous job activity.

Confined Space Simulator Build Options: ROXBOX Models vs. Custom Projects:

We offer both our standard model (shown below) and custom projects. By choosing our ROXBOX Confined Space Simulator model, you are greatly reducing the time and cost of your project, especially from a pre-construction standpoint as all of the designs are already completed and approved. For an added cost, models have various add-ons that you can choose from (such as night vision cameras and an external monitoring station) and can be painted/branded to whatever your preference is to truly make the box your own.

Custom Confined Space Simulator projects allow our customers to design a unit that perfectly fits their needs and matches their brand. With custom projects, we collaborate with our in-house design team to design + build your vision from scratch, bringing a napkin sketch to reality. Therefore, this pathway adds significant cost & time to a project.

ROXBOX Confined Space Simulator FAQs

On-Site Moving: We offer caster wheels for movement on-site. Moving the unit on-site is best done with heavy equipment (forklift or crane).

Short Distance/Local Moving: A tilt-bed tow-truck can easily move the unit locally for a relatively low cost.

Long Distance Moving:  If you are moving the unit long-distance, a low-boy flatbed truck is the ideal transportation method.

Anywhere in the world – that’s the beauty of building our simulators out of shipping containers!

*Some very remote locations may require specialized transportation and logistics – including international shipping on a boat.

ROXBOX offers a 1-year warranty on our work. We take great pride in our craftsmanship.

Yes. The units we offer typically are classified as pieces of equipment and therefore have the same financial ramifications as any piece of business equipment. For more information on financing, visit the “Financing” page under the “How It Works” tab in the menu above.
