Saf-T-Cart 401-14FW Firewall Cylinder Cart

The Saf-T-Cart 401-14FW carries one large oxygen cylinder and one fuel-gas cylinder on one frame, with a steel firewall between them, so the oxygen and fuel gas stay separated while both ride on one cart. It suits a shop that keeps its oxy-fuel rig on the cart between jobs.

Pick the build:

• Standard (401-14FW): one oxygen cylinder up to 9-1/2 in across and one acetylene cylinder up to 12-1/2 in across.
• Propane (401-14FW-P): Saf-T-Cart's product page says it carries a large oxygen cylinder and a 100 lb propane cylinder. Its 2021 drawing shows a 27-1/2 in x 12 in baseplate, 4 in wider than the standard's.

The 14 in the model number is the wheel size, not a cylinder size. Measure across the body of your cylinder, not the cap or the foot ring. The photo shows the standard build. How to check your cylinders.

Why the firewall: OSHA requires oxygen cylinders in storage to be kept 20 ft from fuel-gas cylinders and combustible materials, or separated from them by a noncombustible barrier at least 5 ft high with a fire-resistance rating of at least half an hour (OSHA 1910.253(b)(4)(iii)). Saf-T-Cart states its firewalls are at least 60 in tall, block the line of sight between the oxygen and fuel-gas cylinders and carry a 30-minute burn rating, and says its firewall carts meet and exceed OSHA 1910.253.
