Exposure 1: OSB suitable for uses not permanently exposed to the weather. Panels classified as Exposure 1 are intended to resist the effects of moisture on structural performance as may occur due to construction delays, or other conditions of similar severity.
Class III or C
76-200, smoke developed index <450
Whenever possible, store panels under a roof. Keep sanded panels and appearance-grade products away from high-traffic areas to prevent damage to surfaces. Use pieces of lumber to weigh down the top panel in a stack to reduce warpage from humidity. If moisture absorption is expected, cut steel bands on bundles to prevent edge damage.
If panels must be stored outside, stack them on a level platform supported by at least three 4x4s to keep them off the ground. Place one 4×4 in the center and the other two 4x4s 12 to 16 inches from the ends. Never leave panels or the platform in direct contact with the ground.
Cover the stack loosely with plastic sheets or tarps. Anchor the covering at the top of the stack, but keep it open and away from the sides and bottom to ensure good ventilation. Tight coverings prevent air circulation and when exposed to sunlight, may promote mold or mildew. (Source: APA Builder Tip U450: Storage and Handling of APA Trademarked Panels)
