The APP shall be developed by the Contractor and shall interface with the Contractor's overall Safety and Health Program, such that any portions of the Contractor's overall program referenced in the APP shall be included as appropriate.

The Contractor shall develop the APP in accordance with EM 385-1-1, Appendix A, and shall address each of the elements/sub-elements in the outline contained in the appendix in the order that they are provided in the manual, and as supplemented https://www.e-verify.gov/ https://www.publications.usace.army.mil/Portals/76/Publications/EngineerManuals/EM_385-1-1.pdf https://www.publications.usace.army.mil/Portals/76/Publications/EngineerManuals/EM_385-1-1.pdf herein. If an item is not applicable because of the nature of the work to be performed, the Contractor shall state this exception and provide a justification. The APP shall be written in English by the Prime Contractor and shall articulate the specific work, work processes, equipment to be used, and hazards pertaining to the contract. The non-mandatory APP Checklist, Form A-2 of the EM 385-1-1, may be used to ensure each area of required information has been provided as part of the APP to the Contracting Officer.

The Contractor's APP shall be job-specific and must include work to be performed by subcontractors. It is understood that the APP is submitted prior to work starting and some of the project-specific information is not yet known. If sub-contractors and/or suppliers are not known at the time of initial APP submission, the Contractor shall include the following statement in their APP: "The subcontractors for the following defined features of work (DFOW)/activities are not known at this time, but additional information will be submitted to the APP for acceptance prior to the start of any activities listed." All known information shall be provided and additional information submitted to the Contracting Officer for acceptance, as it becomes known.

Once accepted by the Contracting Officer, the APP and all attachments will be enforced as part of the contract. Disregarding provisions of this contract or the accepted APP is a cause for stopping of that portion of the work at the direction of the Contracting Officer until the matter has been rectified.

Each sub-contractor shall be provided a copy of the accepted APP and a copy shall be available on the worksite at all times. A signature log shall be completed by each sub-contractor supervisor attesting that they have read and understand the APP. All sub-contractors shall comply with the APP.

The Contractor shall provide on-going evaluations of the APP throughout the life of the project. Changes, revisions, and updates to the APP shall be reviewed and accepted by the Contracting Officer, project superintendent, SSHO, and Quality Control Manger. An APP template is provided in Attachment 4.

Risk Management Risk management is a business process that includes the identification, assessment, and prioritization of risks, followed by coordinated and economical application of resources to minimize, monitor, and control the probability and/or impact of unfortunate events to an acceptable level. A risk management assessment tool, such as activity hazard analysis (AHA), job safety analysis (JSA), or job hazard analysis (JHA) shall be developed by the contractor performing the work for each activity, task, or defined feature of work (DFOW). The assessment shall identify the work sequence, specific anticipated hazards, site conditions, equipment, materials, personnel, and the control measures to be implemented to control the hazards. A Risk Assessment Code (RAC) shall be assigned to each job step based on the residual risk remaining after controls are implemented. A RAC shall then be assigned to the overall activity consistent with the highest RAC identified for the job steps. If developed by a subcontractor, the Prime Contractor shall review and approve the assessment before submission to the Contracting Officer. The Risk Assessment shall be signed by the SSHO, Superintendent, QC Manager, and any subcontracting Foreman performing the work. If

Qualified or Competent Persons are required for a particular activity, they shall be identified and included in the assessment, and their competency/qualification identified.

Work shall not begin until the assessment has been accepted by the Contracting Officer and discussed with all engaged in the activity.

These risk assessment tools are considered living documents and shall be updated as needed. If the RAC increases from what was originally accepted by the Contracting Officer, the assessment shall be re-submitted for acceptance prior to work proceeding.

Changes that do not increase the RAC are not required to be resubmitted for acceptance.

The risk assessment shall be developed in accordance with EM 385-1-1 Section 1, or as specified by the Contracting Officer. Risk assessments shall be submitted for review at least 15 working days prior to the start of the activity, task, or defined feature of work is set to begin. The Government reserves the right to require the Contractor to revise and resubmit any documents if they fail to effectively identify the work sequence, specific anticipated hazards, site conditions, equipment, materials, personnel, and the control measures to be implemented.

Each employee performing work as part of an activity, task, or defined feature of work shall review the risk assessment for the activity and sign the signature log designated for the assessment prior to beginning work. A signature log shall be maintained for each risk assessment.

Completed risk assessments need not be submitted at the time of the APP submission, but the Contractor shall identify each activity, task, or DFOW that will require a risk assessment to be completed at the time of submission.

Implementation of Safety and Occupational Health (SOH) Program The Contractor shall employ a minimum of one Competent Person at each project site to function as the primary Site Safety and Health Officer (SSHO) to implement and administer the Contractor’s safety program and the Government-accepted Accident Prevention Plan (APP). The SSHO is a full-time responsibility and shall be an employee other than the supervisor [unless specified differently in the contract and coordinated with the local SOH Office], that reports directly to a senior project, or corporate, official.

The SSHO shall be present at the project site and be located so they have full mobility and reasonable access to all major work operations during the shift. The SSHO shall meet all training and experience qualifications as outlined in EM 385-1-1 Section 01, Paragraph A.17.

5.5.2. Storage

Store and protect materials from damage and weather in accordance with manufacturer's printed instructions, except as specified otherwise. Keep materials clean and dry. Store and maintain adhesives, sealants, primers and other liquid materials in accordance with manufacturers’ recommendations. Utilize insulated hot boxes or other enclosed warming devices in cold weather. Mark and remove damaged materials from the site. Use pallets to support and canvas tarps to completely cover material materials stored outdoors. Do not use polyethylene as a covering. Storage of materials on the roof will not be permitted. Locate materials temporarily in approved areas. Remove unused materials from the roof at the end of each day’s work.

5.5.3. Handling

Prevent damage to edges and ends of roll materials. Do not install damaged materials in the work. Select and operate material handling equipment so as not to damage materials or applied roofing. Do not use materials contaminated by exposure or moisture. Remove contaminated materials from the site. When hazardous materials are involved, adhere to the special precautions of the manufacturer. Adhesives may contain petroleum distillates and may be extremely flammable; prevent personnel from breathing vapors, and do not use near sparks or open flame.

Environmental Requirements The temperature of the roofing materials shall be as required by the manufacturer. Do not install EPDM sheet roofing during high winds or inclement weather, or when there is ice, frost, moisture, or visible dampness on the substrate surface, or when condensation develops on surfaces during application.

Unless recommended otherwise by the EPDM sheet manufacturer and approved by the Contracting Officer, do not install EPDM sheet when air temperature is below 40 degrees F or within 5 degrees F of the dew point. Follow manufacturer's printed instructions for installation during cold weather conditions.

Wind conditions shall be suitable for installation of insulation: Wind chill may affect the proper application temperatures of materials; hot materials may be blown about, creating safety dangers; insulation boards may become difficult and hazardous to handle; wrappers, coverings, and other debris may become airborne, and possibly contaminate laps and seams.
