# APPENDIX E SAMPLE FALL PROTECTION PLAN NON-MANDATORY GUIDELINES FOR COMPLYING WITH 1926.502(K) (cont.) ## Safety Monitoring System A safety monitoring system means a fall protection system in which a competent person is responsible for recognizing and warning employees of fall hazards. The duties of the safety monitor are to: 1. Warn by voice when approaching the open edge in an unsafe manner. 2. Warn by voice if there is a dangerous situation developing which cannot be seen by another person involved with product placement, such as a member getting out of control. 3. Make the designated erectors aware they are in a dangerous area. 4. Be competent in recognizing fall hazards. 5. Warn employees when they appear to be unaware of a fall hazard or are acting in an unsafe manner. 6. Be on the same walking/working surface as the monitored employees and within visual sighting distance of the monitored employees. 7. Be close enough to communicate orally with the employees. 8. Not allow other responsibilities to encumber monitoring. If the safety monitor becomes too encumbered with other responsibilities, the monitor shall (1) stop the erection process; and (2) turn over other responsibilities to a designated erector; or (3) turn over the safety monitoring function to another designated, competent person. The safety monitoring system shall not be used when the wind is strong enough to cause loads with large surface areas to swing out of radius, or result in loss of control of the load, or when weather conditions cause the walking-working surfaces to become icy or slippery. ## Control Zone System A controlled access zone means an area designated and clearly marked, in which leading edge work may take place without the use of guardrail, safety net or personal fall arrest systems to protect the employees in the area. Control zone systems shall comply with the following provisions: 1. When used to control access to areas where leading edge and other operations are…

# APPENDIX E SAMPLE FALL PROTECTION PLAN NON-MANDATORY GUIDELINES FOR COMPLYING WITH 1926.502(K) (cont.) ## I. Statement of Company Policy (cont.) Each employee must understand their value to the company; the costs of accidents, both monetary, physical, and emotional; the objective of the safety policy and procedures; the safety rules that apply to the safety policy and procedures; and what their individual role is in administering, implementing, monitoring, and compliance of their safety policy and procedures. This allows for a more personal approach to compliance through planning, training, understanding and cooperative effort, rather than by strict enforcement. If for any reason an unsafe act persists, strict enforcement will be implemented. It is the responsibility of (name of competent person) to implement this Fall Protection Plan. (Name of Competent Person) is responsible for continual observational safety checks of their work operations and to enforce the safety policy and procedures. The foreman also is responsible to correct any unsafe acts or conditions immediately. It is the responsibility of the employee to understand and adhere to the procedures of this plan and to follow the instructions of the foreman. It is also the responsibility of the employee to bring to management's attention any unsafe or hazardous conditions or acts that may cause injury to either themselves or any other employees. Any changes to this Fall Protection Plan must be approved by (name of Qualified Person). ## II. Fall Protection Systems to Be Used on This Project Where conventional fall protection is infeasible or creates a greater hazard at the leading edge and during initial connecting activity, we plan to do this work using a safety monitoring system and expose only a minimum number of employees for the time necessary to actually accomplish the job. The maximum number of workers to be monitored by one safety monitor is six (6). We are designating the following trained emp…

# APPENDIX E SAMPLE FALL PROTECTION PLAN NON-MANDATORY GUIDELINES FOR COMPLYING WITH 1926.502(K) Employers engaged in leading edge work, precast concrete construction work and residential construction work who can demonstrate that it is infeasible or creates a greater hazard to use conventional fall protection systems must develop and follow a fall protection plan. Below are sample fall protection plans developed for precast concrete construction and residential work that could be tailored to be site specific for other precast concrete or residential jobsite. This sample plan can be modified to be used for other work involving leading edge work. The sample plan outlines the elements that must be addressed in any fall protection plan. The reasons outlined in this sample fall protection plan are for illustrative purposes only and are not necessarily a valid, acceptable rationale (unless the conditions at the job site are the same as those covered by these sample plans) for not using conventional fall protection systems for a particular precast concrete or residential construction worksite. However, the sample plans provide guidance to employers on the type of information that is required to be discussed in fall protection plans. ## SAMPLE FALL PROTECTION PLANS Fall Protection Plan For Precast/Prestress Concrete Structures This Fall Protection Plan is specific for the following project: <table><tr><th>Location of Job</th></tr><tr><td>Erecting Company</td></tr><tr><td>Date Plan Prepared or Modified</td></tr><tr><td>Plan Prepared By</td></tr><tr><td>Plan Approved By</td></tr><tr><td>Plan Supervised By</td></tr></table> The following Fall Protection Plan is a sample program prepared for the prevention of injuries associated with falls. A Fall Protection Plan must be developed and evaluated on a site by site basis. It is recommended that erectors discuss the written Fall Protection Plan with their OSHA Area Office prior to going on a jobsite. ## I. Statement of Compa…
