Department of Transportation (DOT) & Hazmat Fire Protection

No matter what type of cylinders you use for your business, it’s important that they be properly tested to ensure they are in working order. At Fire Pros, you can count on our certified Department of Transportation (DOT) and hazmat staff to conduct tests on cylinders, tanks, and cartridges. We also offer cylinder recharge, cylinder maintenance, and cylinder exchange services.

We follow fire protection regulations and codes set by DOT and hazmat policies when testing cylinders. We also check for pressure tightness and test the cylinder’s structural integrity. This is all part of our standard cylinder testing services.
