This portable fire extinguisher stand holds a 2-1/2, 5, 10, or 20 lb. fire
extinguisher. The base holds up to 35 lbs. of sand for stability.
Note: OSHA 29 CFR 1910.157(c)(1) requires extinguishers to be “mounted,
located and identified” so they are readily accessible. OSHA's separate
requirement for an “approved” product applies specifically to the portable fire
extinguisher, not expressly to the stand.
