5. MAINTENANCE OF YOUR NINJA LADDER
At the beginning of each play season:
• Check all moving parts including swing seat, ropes, cables, and chains for wear, rust, or other
deterioration. Replace as needed.
• Check all wood members for deterioration and splinters. Sand down splinters and replace deteriorating
wood members.
• X.3.1.1 Loose-Fill Materials:
X.3.1.1 Maintain a minimum depth of 9 in. (23 cm) of loose-fill materials such as wood mulch/chips,
engineered wood fiber (EWF), or shredded/recycled rubber mulch for equipment up to 8 ft. (2.5 m); and 9
in. (23 cm) of sand or pea gravel for equipment up to 5 ft. (1.5 m) high. NOTE: An initial fill level of 12 in.
(30 cm) will compress to about a 9 in. (23 cm) depth of surfacing over time. The surfacing will also
compact, displace, and settle, and should be periodically refilled to maintain a least a 9 in. (23 cm) depth.
Twice a month during play season:
• X.3.1.1 Loose-Fill Materials: X.3.1.1 Maintain a minimum depth of 9 in. (23 cm) of loose-fill materials
