Rubbermaid's "Caution Wet Floor" sign is a must for any commercial building or school where the floors get mopped regularly. Its folding design means it fits snugly in standard janitor carts. The caution message is on both sides of the sign, so people coming from either direction will be warned in advance. The durable plastic will not rust, corrode, or fade over time. The 25-inch two-sided, bright yellow sign meets OSHA requirements.
