How far can a platform extend over its support if it is 10 feet or less in length?

• A. 10 inches (25 cm)
• B. 8 inches (20 cm)
• C. 12 inches (30 cm)
• D. 15 inches (38 cm)

Answer: (C)

When a platform is 10 feet or less in length, industry standards dictate the maximum allowable extension over its support is typically 12 inches (30 cm). This limit is established to ensure safety and stability, minimizing the risk of tipping or failure due to excessive weight or shifting loads. The specification allows for a reasonable overhang that can accommodate various construction scenarios while adhering to safety codes and regulations. Other options provide either shorter extensions or values that do not align with standard best practices in construction safety. Therefore, the maximum safe extension for a platform of this size is indeed 12 inches.
