Saf-T-Cart 552-16FW Firewall Cylinder Cart

The Saf-T-Cart 552-16FW carries one large oxygen cylinder and one large fuel-gas cylinder with a steel firewall between them, so the oxygen and fuel gas stay separated while both ride on one cart. Two 1/4 in steel permaclamps hold the cylinders, 16 in pneumatic tires carry it over rough ground (the -101611 has semi-pneumatic hard-rubber wheels instead), and a lifting eye lets you hoist it. Saf-T-Cart says it suits large construction and industrial sites.

Pick the build:

• Standard (552-16FW): one oxygen cylinder up to 9-1/2 in across and one acetylene cylinder up to 12-1/2 in across. It fits the common 300 cu ft acetylene cylinder, about 12 in across.
• 8-1/2 in acetylene (552-16FW-SM): for 8-1/2 in acetylene cylinders (Saf-T-Cart's catalog), with a small permaclamp, so a smaller cylinder does not sit loose.
• Propane (552-16FW-P): an oxygen cylinder up to 9-1/2 in and a propane cylinder up to 15 in across (Saf-T-Cart's product page), on a 27-1/2 in x 11-29/32 in baseplate (its 2020 drawing).
• Forklift pockets (552-16FW-FL): adds forklift pockets of heavy-duty square steel tubing (Saf-T-Cart's product page).
• Semi-pneumatic wheels (552-16FW-101611): the standard cart on Saf-T-Cart's 101611 wheels, 16 in semi-pneumatic (hard rubber), rated 280 lb each.
• Stainless steel floor (552-16FW-SS): the standard cart with a stainless steel floor.

The 16 in the model number is the wheel size, not a cylinder size. The photos show the standard, -SM, propane and forklift builds. The -101611 and -SS are shown by the standard build's photo; their wheels or floor differ as described above. 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. When a firewall cart is the right call: the firewall requirement. How separation works in a shop or on a jobsite: gas cylinder storage guide.
