Which material is acceptable for treads used for temporary service?

Wood or other solid materials are deemed acceptable for treads used in temporary service because they provide a durable and sturdy surface necessary for safe passage. These materials can typically support the weight and wear from foot traffic and equipment associated with construction or temporary setups.

Using wood or other solid materials aligns with safety standards, as they can be easily constructed or adjusted on-site, making them practical for temporary applications. Additionally, solid materials offer better traction and stability, reducing the risk of slips and falls, which is a significant consideration in occupational safety.

Other materials, while they might have specific advantages in certain contexts, may not be as suitable for the varying conditions encountered during temporary service work. For example, plastic may be less durable and more prone to breaking or deforming under heavy loads, metal may present issues with slip resistance or require additional treatment for safety, and rubber could lack the structural integrity needed for heavier foot traffic or equipment passage. Thus, wood or similar solid materials remain the preferred choice for treads in temporary service applications.
