Trenches less than 5 feet in depth shall also be protected when examination of the ground indicates hazardous ground movement may be expected. The safe angle of repose for soil conditions and bracing systems shall be determined by a qualified person.
Refer to the EM 385 for specific details. All excavations must follow 29CFR1910.28, OSHA Standards.
Here is a general listing of scaffolding requirements (for a complete list see the EM 385 and 29CFR1910.28):
Scaffolds or platforms are required for all work that cannot be done safely from the ground.
Work requiring lifting of heavy materials or substantial exertion cannot be done from ladders.
Scaffolds must be kept clear of ice, snow, grease, mud, and such.
All scaffolds and walkways must beat least 18 inches wide.
Ladder jacks, lean-tos, and prop scaffolds are prohibited.
Scaffolds must be placed on a firm, smooth foundation and may not be placed on loose bricks, blocks, or other unstable objects.
Planking must be lapped at least 12 inches.
The EM 385 and 29CFR1910.28 list the correct dimensions and type of scaffold material.
A scaffold in excess of 6 feet in height (4 where horizontal dimension is less than 45 inches) requires standard railing on open sides and ends.
The following safety equipment is required on all project sites. See the EM 385 for additional information.
1. Emergency Plans - Each jobsite must have posted the location of the nearest phone with the telephone numbers and reporting instructions for ambulance, hospital, physician, police, and fire department personnel.
2. First-Aid/CPR Qualified Personnel - If a medical facility is not readily accessible (due to time or distance), two crew members must be first-aid and CPR qualified.
