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

The Saf-T-Cart 552-16H-FW is Saf-T-Cart's 552-16FW with a hood over the cylinder tops. It carries an oxygen cylinder and an acetylene cylinder with a steel firewall between them, held by two 1/4 in steel permaclamps, with a toolbox, a lifting eye rated 1,000 lb and 16 in pneumatic tires. Saf-T-Cart says it suits large construction and industrial sites.

Which cylinders fit: Saf-T-Cart lists cylinder capacity as 9-1/2 in and 12-1/2 in diameter. How to check your cylinders.

Saf-T-Cart's 2017 catalogs list this cart taller (75 to 78 in) and wider (35 to 38 in), on a 13 in x 24 in floorplate. Saf-T-Cart's 2020 drawing gives 70-1/2 in tall and 25-1/2 in across the frame, with the wheels mounted outside the frame. If the width across the wheels matters for your doorways, ask us before ordering.

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.
