MasTec Network Solutions, LLC has other ES&H requirements that may apply depending on the Contractor's scope of work, site-specific conditions, or when specialized equipment is used. For example, Contractors may be required to submit specific plans to MasTec Network Solutions, LLC for approval prior to starting certain work activities, such as:

• Fall protection plan when working where a fall hazard may exist from a height greater than six feet;
• Standard operating procedures (e.g., performing service or maintenance on equipment or machinery where an un-expected release of hazardous energy may occur, conducting work in a confined space, excavation, or trench); and
• Health protection procedures where workers health may be jeopardized (e.g., exposure to noise above 85 decibels, working in a contaminated environment, handling blood or other bodily fluids).

If selected to bid for work, Contractors will be provided with more detailed information on MasTec Network Solutions, LLC's ES&H requirements. Contractors are expected to demonstrate in their bid proposal that they have applied MasTec Network Solutions, LLC's ES&H requirements to the hazards associated with their scope of work. MasTec Network Solutions, LLC will evaluate Contractor responses and the results will be a factor in determining if the Contractor is awarded the work.

Contractors are responsible for selecting and managing their suppliers and lower-tier subcontractors to the same standards and requirements that apply to their scope of work as set forth in their contract with MasTec Network Solutions, LLC. In the event that MasTec Network Solutions, LLC's ES&H requirements exceed a governmental law, regulation, or requirement, the more stringent requirement will apply. Contractors will be responsible for conducting and documenting regular inspections and periodic evaluations of their work activities to ensure compliance with the project's ES&H requirements. Contractor's inspection and audit results will be made available to MasTec Network Solutions, LLC for review.

MasTec Network Solutions, LLC has adopted a "Zero Accident" philosophy that all work related accidents, incidents, injuries, and illnesses are preventable. This philosophy promotes:

• Constant awareness of each individual's responsibility to identify and eliminate unsafe practices and conditions in the work place;
• Building a safety team mentality where all workers contribute to the effort and each supervisor is fully aware of their team's capabilities and limitations and is held accountable for the team's actions; and
• Building a culture where everyone accepts responsibility and accountability for their own safety and health, as well as the safety and health of their co-workers.

Contractors are responsible for complying with all governing environmental laws, regulations, permits, and project plans [e.g., MasTec Network Solutions, LLC's Construction Environmental Control Plan (CECP)] and are expected to employ effective field control measures, such as:

• Storm water management;
• Spill prevention and response;
• Erosion and sediment control;
• Air emissions and dust control;
• Hazardous materials management;
• Waste management;
• Stop work procedures in the event of an unanticipated discovery (e.g., human remains, artifacts); and
• Cleanup and restoration of disturbed areas.

Contractors, sub-tier contractors, and suppliers will be required to comply with all access restrictions, including prohibitions on access to sensitive resources (e.g., wetlands, archaeological sites, special wildlife habitats) or areas adjacent to the worksite.

Depending on the contract amount and/or the scope of work, Contractors may be required to develop an Environmental Compliance Plan that conforms to all environmental permits governing the project and the requirements of the project-specific CECP.

Contractors are responsible for complying with all applicable safety and health (S&H) laws, regulations, codes, the project's S&H Plan, and the Contractor's own S&H requirements as they apply to their scope of work. Contractors may be required to provide a written S&H Plan that specifically addresses the hazards and corresponding mitigation measures associated with their scope of work. MasTec Network Solutions, LLC receipt, review, and approval of this plan is a condition precedent for mobilization payment.

Unless specified otherwise, Contractors will be responsible for obtaining all necessary safety certifications and permits applicable to their scope of work. Prior to starting work, Contractors will demonstrate to MasTec Network Solutions, LLC that all applicable certifications and permits have been obtained.

Contractors will be responsible for promptly reporting all injuries and near misses to MasTec Network Solutions, LLC's onsite management and conducting an incident investigation in a timely manner. The incident investigation should focus on identifying and documenting the root cause(s), finding(s), and corrective action(s) to prevent a reoccurrence of the incident.
