3.1.7 Respiratory Protection

A written respiratory protection program meeting the requirements of 29 CFR 1910.134 is required for each contractor using respiratory protection at the site. Contractors shall submit a copy of their written respiratory protection program for review by the DDC/Site ES&H director or designee prior to respirator use.

3.2 CONFINED SPACE ENTRY

All confined space entries shall be controlled through the use of a permit system (Note: this includes spaces that meet the OSHA definition of nonpermit-required confined spaces).

Contractors shall comply with their own confined space entry program, the use of which requires review and approval by the WTC Emergency Site ES&H director or his designee.

3.3 EXCAVATION, TRENCHING AND PENETRATION

Contractors shall ensure that all personnel performing work in an excavation have awareness training which includes a discussion of the hazards and control measures associated with underground utilities, cave-ins, access and egress, use of protective systems (benching, shoring, sloping, trench boxes), potential atmospheric hazards, equipment operations hazards, water accumulation hazards, stability of adjacent structures, and the contractors excavation inspection program. Contractors shall assign a competent person to each excavation where a hazard to personnel, equipment or facilities may exist. The competent person shall be available on-site (at the excavation area as necessary) and involved in all important aspects of planning and executing excavation work including soil classification, identification and use of protective systems and permit approval. Contractors shall ensure that all employees in an excavation are protected from cave-ins by an adequate protective system for all excavations which are at least 5 feet or deeper, and for excavations less than 5 feet where examination by a competent person indicates a potential for cave-ins. A JHA shall be developed for personnel who are working in and around an excavation that is 4 feet or deeper or where the potential for cave-in is present. Excavated materials (spoils) shall be placed a minimum distance of 2 feet from the edge of the excavation. A means of egress shall be provided, ever 25 feet of lateral distance, from all excavations 4 feet or greater.
