July 24, 2025 [Tank Storage]- Square Robot, Inc., a global leader in robotic tank inspections, has knocked down two more barriers for its onstream, robotic tank inspections.

 
The SR-3 submersible robot has formally received the NEC/CEC Class I Division 2 (C1D2) certification and Square Robot’s Side Launcher has received the NEC/CEC Class I Division 1 (C1D1) certification.
 

The C1D2 and C1D1 certifications were issued by third-party Nationally Recognized Test Lab, FM Approvals, proving Square Robot’s systems safe for use in hazardous locations.

As part of the operating methodology for launching into floating roof tanks, often containing low flashpoint products, the Side Launcher’s C1D1 certification confirms the safe deployment and retrieval of the SR-3 robot in these environments. The SR-3 robot and Side Launcher became commercially available in Autumn 2023, after completing initial milestone testing in partnership with ExxonMobil.

These certifications expand Square Robot’s service portfolio, allowing it to tackle a market that was previously only available for inspections by taking the tank offline. The combination makes Square Robot the first robotic company to safely inspect a new group of low flash point product tanks – the full list of which can be found here.

‘Our customers have been eagerly awaiting the certifications since our witness testing in 2024. With the C1D2 and C1D1 stamps now in hand, it opens up a new group of tank candidates available for robotic tank inspections. We’re proud to be pioneers in this industry, and continue to develop new technology based on our clients needs,’ says John Hazel, VP operations & chief inspector.
