SOP 138-68HV

TRENCHING AND EXCAVATION

VA Hudson Valley Health Care System Issue Date: 5.28.2013 Update: 5.28.2016

1. PURPOSE: To establish policy, responsibilities, procedural guidance, and safety requirements for trenching and excavation operations by VA Hudson Valley HCS and/or contractor personnel.

2. POLICY:

a. The VA Hudson Valley HCS has established mechanisms to operate under the rules and regulations as outlined by the U.S. Department of Labor, Occupational Safety and Health Standards covering all excavations.

b. The mechanisms include the use of support systems, sloping and benching systems, and other systems which are used as protection against excavation cave-ins, the means of access to and egress from excavations and also the employees’ exposure to vehicular traffic, falling loads, hazardous atmospheres, water accumulation, and unstable structures in and adjacent to excavations.

3. RESPONSIBILITIES:

a. The Chief, Engineering Service is responsible for the implementation and reinforcing the requirements outlined in this policy

b. The Engineering Shop Supervisors or designees are responsible for:

1) Ensuring that the excavation or trench is safe and in compliance with 29 CFR 1926, Subpart P

2) Acting as "competent persons" after the completion of excavation training, as designated.

c. Engineering Employees are responsible for following the requirements of this policy and 29 CFR 1926,Subpart P.

d. Project Section Employees are responsible for ensuring contractors comply with the requirements of this policy and 29 CFR 1926, Subpart P.

4. PROCEDURES:

a. Definitions:

1) Cave-in means the separation of a mass of soil or rock material from the side of an excavation either by falling or sliding, in sufficient quantity so that it could entrap, bury or otherwise injure and immobilize a person.

2) Competent person means one who is capable of identifying existing and predictable hazards in the environment, or working conditions which are unsanitary, hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them.

3) Excavation means any man-made cut, cavity, trench, or depression in an earth surface, formed by earth removal.

4) Hazardous atmosphere means an atmosphere which by reason of being explosive, flammable, poisonous, corrosive, oxidizing, irritation, oxygen deficient, toxic, or otherwise harmful, may cause death, illness, or injury.

5) Trench (Trench excavations) means a narrow excavation (in relation to its length) made below the surface of the ground. In general the depth is greater than the width. If the width of a trench (measured at the bottom) is not greater than 15 feet, then the excavation is also considered a trench.

6) Bell-bottom Pier Hole means a type of shaft or footing excavation, the bottom of which is made larger than the cross section above to form a bell shape.

b. Mandatory Requirements:

1) New York state law requires that you call Dig Safety New York prior to any type of excavation work. Call center operators at Dig Safely New York are available 24 hours a day, seven days a week to receive and process calls to the toll-free phone number at (1- 800-962-7962).

Customer Service Representations will provide a faxed copy of the request with a ticket reference confirmation number. Each Excavation request requires a (2) to (10) day advance notice of the planned start date (not counting the day of the call).

Dig Safety New York will notify all member utilities of the pending excavation so each can come out and mark the location of their underground lines. Confirmation must be received from each utility and have marked the ground area being disturbed. Work may not start before the stated commencement date, unless you have been notified by EVERY operator that they have no underground utilities in your work area.

2) The walls and faces of trenches 5 feet or more deep and all excavations in which employees are exposed to changes from moving grounds or cave-in shall be guarded by a shoring system, sloping of the ground or a shielding system.

3) Trenches 4 feet or more deep shall have an adequate means of exit such as ladders, steps, or ramps located so as to require no more than 25 feet of lateral travel. Ladders must be secured and must extend 36 inches above the landing.

4) In all excavations which employees may be required to enter; all equipment, excavated material, or other material shall be effectively stored and retained at least 2 feet or more from the edge of the excavations.

5) Daily inspections of excavations, protective systems, and adjacent areas shall be made by a competent person for any hazardous conditions which might exist. An "Excavation Checklist" (Attachment A) will be used as a guide for compliance and will be filled out for each excavation or trench. Where a competent person finds such a hazard, exposed employees shall be removed from the area until actions have been taken to insure their safety. These inspections are required only when employee exposure is reasonably anticipated.

6) All material removed from an excavation will be considered Class C soil unless otherwise determined. All protective systems will; therefore, be constructed for Type C soil. The maximum allowable slope will be 35 degrees (1 ½:1) on all Type C excavations.

7) When an excavation is near vehicular traffic, exposed employees shall be provided with, and shall wear warning vests or other suitable garments marked with or made of reflectorized or high-visibility material.

8) Prior to opening an excavation, as-built plans or any other feasible method will be used to determine the location of utility installations such as sewer, telephone, fuel, electrical/water lines, or any other installation.

c. Additional Requirements:

1) In excavations where hazardous atmospheres or engulfment may exist, the excavation will be treated as a permit-required confined space. The procedures of the confined space policy shall be followed.

2) Mobile equipment shall be protected by using hand signals, barricades, or stop logs if operator visibility is restricted.

3) Excavations shall be protected from the accumulations of water by water-removal equipment, dikes, diversion ditches, or other suitable means. Excavations subject to heavy rains or run-off shall be inspected by a competent person prior to entering the excavation.

4) Employees shall be protected with personal protective equipment for the protection of the head, eyes, respiratory tract, feet and other body parts as required.

5) Unattended excavations or trenches will be effectively guarded against unauthorized entry by chain link fencing no lower than 10 feet high that will include appropriate construction-site signage as necessary.

6) Unattended machinery, equipment and construction dumpsters must be secured by a chain link fence no lower than (8) feet high that will include warning signage

6) Steel Trench Plates are permitted as an alternative to chain link fencing providing that the plates extend beyond the edges of the trench wall a minimum of (12”) inches.

7) Excavated areas protected by temporary trench plates must be protected by a ( 48”) high orange colored Snow/Safety fence staked at intervals not less than every (8’)

8) Signage reading: Construction Site, Hard Hats Required must be attached to each side of any fencing installed every 10 feet or each fence panel.

9) No employee shall be permitted underneath loads handled by lifting or digging equipment. Employees must stand away from any vehicle being loaded or unloaded to avoid being struck by any spillage or falling materials.
