OSHA 1926, Subpart N- Cranes, Derricks, Elevators- does not appear to DIRECTLY address dunnage under outriggers. However- the standards DO require that a piece of equipment be operated as the maker instructed- and makers will recommend dunnage for almost all surfaces- to spread the ground load, and reduce outrigger slippage.
In most circumstances, adequate dunnage will be minimum 3 inch thick hardwood, tightly spaced (no gaps). Plywood, pallets, and scrap should be avoided. For size, a rough rule of thumb is to divide crane capacity in tons by 5. That will equal the number of sq ft of dunnage under each outrigger pad. Example- 20 ton crane- divide by 5=4. 4 sq ft- or a 2x2 pad, should provide adequate support under MOST soil conditions. Extremes of moisture may require more.
