*** PSF Ratings and depths are based on short term exposure with excavation open a period of time equal to 24 hours or less. Consult manufacturer should long term exposure be required. Depths are based on A, B, C soil types are described in OSHA's 29 CPR Part 1926 Subpart P, October 31, 1989 with Type A not exceeding 25 PSF per foot of depth. Type B not exceeding 45 PSF per foot of depth. Type C-60 not exceeding 60 PSF per foot of depth and Type C-80 not exceeding 80 PSF per foot of depth. Determine actual soil pressures and consult Manufacturers Tabulated Data prior to each use.
