3185.090.001 01 50 01-1

SECTION 01 50 01

HEALTH AND SAFETY PROVISIONS

PART 1 - GENERAL

1.01 REQUIREMENTS

A. The Contractor's attention is directed to the fact that the work site is adjacent to an existing refuse landfill and that unsafe conditions may occur. The Contractor is advised that leachate, methane, hydrogen sulfide and other toxic gases may be encountered in excavations for this project.

B. The Contractor shall be responsible to monitor working conditions at all times during construction and, as necessary, to provide appropriate protective clothing, equipment and facilities for his personnel, and to establish workplace procedures to ensure their safety, and to enforce the use of these procedures, equipment and facilities in accordance with the following guidelines:

1. Safety and Health Regulations Promulgated by the U.S. Department of

Labor

2. OSHA:

a. 29 CFR 1910 – Occupational Safety and Health Standards

b. 29 CFR 1920 – Safety and Health Regulations for Construction

c. 30 CFR 1 to 199 – Mine Safety and Health Administration

3. U.S. Environmental Protection Agency Interim Standard Operating Safety Guides – Office of Emergency and Remedial Response – Hazardous Response Support Division, Rev. September 1982.

4. U.S. Environmental Protection Agency Medical Monitoring Program Guidelines.

C. The Contractor shall implement a Health and Safety protection program. The program shall include provisions for stations allowing workers to wash and to put on and remove protective clothing, and stations for vehicles to be cleaned, if necessary, before leaving the site.

D. The Contractor shall engage a qualified Health and Safety expert having experience in similar landfill conditions, to monitor site conditions and recommend all necessary Health and Safety protection for the Contractor’s personnel and the personnel of the Owner and Engineer, as may be affected.

E. The Contractor shall comply with all Federal, State and local safety requirements related to the presence of combustible and nausea-inducing gases.

F. The Contractor shall comply with all health and safety provisions included in the Owner’s service agreement.

HEALTH AND SAFETY PROVISIONS 2.23

01 50 01-2 3185.090.001

G. In addition to the above requirements, the Contractor shall comply with the following requirements:

1. All construction equipment on the site shall be equipped with vertical exhaust pipes or a sparkproof exhaust.

2. Smoking shall not be permitted in any area where gases can accumulate.

3. When working in the presence of a detectable concentration of methane, the soils shall be wetted to the satisfaction of the Engineer.

4. Welding or open flames shall not be permitted in enclosed areas. In other areas in which a detectable concentration of methane is found, ground mats shall be used.

5. Toxic gas indicators, combustible gas indicators, and fire extinguishers shall be available at all times during operations. Continuous monitoring shall be employed with the Contractor furnishing daily to the Engineer, three (3) copies of a certified statement of their findings.

H. If, at any time, the Owner or the Engineer is apprised of a safety hazard which demands immediate attention because of its high potential for harm to public travel, persons on or about the work, or public or private property, the Owner or the Engineer shall have the right to order such safeguards to be erected and such precautions to be taken as necessary and the Contractor shall comply with such orders. If, under such circumstances, the Contractor does not or cannot immediately put the work into proper and approved condition, or if the Contractor or his representative is not upon the site so that he can be notified immediately of the insufficiency of safety precautions, then the Owner may put the work into such a condition that it shall be, in his opinion, in all respects safe, and the Contractor shall pay all expenses of such labor and materials as may have been used for this purpose by him or by the Owner. The fact that the Owner or the Engineer does not observe a safety hazard or does not order the Contractor to take remedial measures shall in no way relieve the Contractor of the entire responsibility for any costs or claims for loss, damage, or injury by or against any party sustained on account of the insufficiency of the safety precautions taken by him or by the Owner acting under authority of this Section.

I. The Contractor is alerted to the fact that conditions of high hazard are present or can be present at the site during the performance of the work. It is the responsibility of the Contractor to take appropriate safety precautions to meet whatever conditions of hazard may be present during the performance of the work, whether reasonably foreseeable or not. The safety conditions enumerated in the Technical Specifications are the minimum permissible and neither the Owner nor the Engineer make any representation that the safety standards provided herein will be adequate to meet all eventualities. The Contractor is therefore alerted to the fact that it shall be its responsibility to anticipate and provide such additional safety precautions, facilities, personnel and equipment as shall be necessary to protect life and property from whatsoever conditions of hazard are present or may be present.

2.23 HEALTH AND SAFETY PROVISIONS

3185.090.001 01 50 01-3

J. The Contractor shall, at a minimum, supply and erect highly visible safety fencing a minimum of three (3) feet in height around all construction areas that pose a threat to safety. The Contractor shall erect safety fencing at this own discretion and as directed by the Engineer and shall maintain such fencing until such a time that the potential safety hazard has been rectified. Upon final completion of construction all safety fencing shall be removed offsite by the Contractor, unless otherwise requested by Owner. Safety fencing requirements of OSHA shall be enforced by the Contractor for all subcontractors on-site.
