Fall Protection
Not anchor - a point of attachment blocked for lines of rescue, thin straps, or devices of deceleration. An anchoring must be able to support a minimum dead load of five thousand (5.000) books (2.268 kilogrammes) for each person attached to him. A point of anchor is often a beam, a beam, a column, or a floor. Nobody qualified - very supervisor who was trained to inspect fall-to stop the equipment such as the horizontal and vertical lines of rescue. Thin strap - a cord (steel or nylon cable) adapted to support a person. Line of rescue - a cord vertically suspended with an end attached to a stationary object (such as a structural member), able to support at least five thousand (5000) books (2.268 kilogrammes) of dead and different load of the end fixed at a harness of thin strap or safety. Inspector qualified - all craftsperson or supervising tested which showed with the projet/à management of site its capacity and competence to inspect the equipment. Retractable line of rescu! e - fall-to stop the device which allows the free voyage, without loose cord, but the locks immediately when a fall starts. Retractable lines of rescue can be used, but the horizontal movement must be limited. Encavateurs of cord (Fall-Interceptor) - automatic devices of line of rescue which act by inertia (resistance to the movement) to seize the line of rescue if a fall occurs. Encavateurs of cord are employed when the vertical movement is required, like the work of the chairs of boatswain or the suspended scaffolding. Harness of safety - a harness of safety is an approved design of the belts which can be fixed about the body of the employees to some extent to distribute fall-stop the surplus of forces at least the thighs, basin, size, trunk, and the shoulders, with means of attaching it to other components of a personnel fall-stop the system. Static line or line of overhead line - a cable or a cord tied up horizontally and/or vertically from one substantial object to ano! ther, to provide average displacement between these two object! s all wh ile maintaining the protection of fall between these objects. Structural/substantial object - any object with which one can join a line of rescue or a thin strap which will support five thousand (5000) books (2.268 kilogrammes) of dead APPROACH of weight.SYSTEMATIC TO FALL RISK MANAGEMENT1. The elimination of fall the first stage in this approach is to evaluate the place of work and work itself at the most preliminary stages of design/technology of the projet/de site and during the stages of planning of all work. The objective is to eliminate all the risks from fall. This evaluation of the projet/de site and the assistances of work not only eliminate from the risks but also identify alternative approaches with the work which can mesurablement increase the productivity. The addressing of the protection of fall in the phases early of a projet/d' site means that safety can be conceived in the process of work. For example, the project/site can be conceived so that anchorings to ! fix fall-stop systems are provided to the strategic places in all the project/site, of this fact improving safety and lowering costs.2. The prevention of fall the second stage in protection continues of fall also requires to evaluate the processes of work and place of work. If one cannot completely eliminate from the risks of fall during the first stage, management must adopt a proactive approach with the prevention of the falls by improving the place of work. The installation early of the staircases, rambardes, the barriers, and the systems of restriction of voyage can ensure a sure work environment.3. The fall stopping the third stage, the last line of defence counters falls, is to employ fall-to stop the equipment. To employ fall-to stop the equipment, however, only after determining that one cannot eliminate from the potential falls by changing the procedures of work or the place of work. The equipment such as harnesses, thin straps, shock absorbers, fall-interceptors, ! lines of rescue, anchorings, and nets of safety can reduce the! risk of damage if a fall occurs. To evaluate the place of work carefully and to work the processes to choose the most suitable equipment and to install it and employ plans of protection WRITTEN by correctly.PREPARING of autumn of PLANS of PROTECTION of FALL will be prepared for high work if the risks of fall exist. Where the risks of fall are significant, the plans should be in the writing. The project/management of site is responsible for determines r quels travaux exigent des plans écrits. La condition pour des plans écrits devrait être incluse dans tous les contrats applicables. Consulter votre directeur de sûreté/directeur pour l'aide en développant l'INSTALLATION écrite de plans.DESIGN DES ÉQUIPEMENTS que machiner devrait inclure la gestion de risque de chute dans toutes les conceptions et devrait considérer ce qui suit : Fournissant l'équipement qui permettra à des équipements d'être actionnés à partir du niveau de catégorie ou d'un accès approuvé de plateforme ou d'entreti! en. Le employant les méthodes de construction qui permettent à l'équipement d'être relié/l'ont installé tandis que sur la terre à éliminer élevait le travail. Dans les cas où le travail élevé est nécessaire, installant des dispositifs d'empêchement de chute tels que des rails sur les objets tandis que sur la terre pour faciliter l'empêchement de chute. Indiquant et insistant sur le fait que les constructeurs fournissent les escaliers et les rambardes permanents avant que de l'acier soit érigé. De cette façon, les escaliers et l'acier peuvent être érigés simultanément, améliorant non seulement la sûreté, mais également l'efficacité. Les employés auront l'acce sûr ss and egress, and the necessity of climbing temporary ladders will be reduced or eliminated.If fall hazard elimination or prevention is not available, identify or install engineered anchor points to facilitate the use of fall-arresting equipment during construction and future maintenance of the facility.TRAIN! ING All personnel performing work at elevated positions shall ! meet the following requirements: must be trained in the use, inspection, and maintenance of fall-arrest systems; must demonstrate competency in initial training; must undergo refresher training as required by changes in the workplace and/or equipment, or as other events indicate that refresher training may be required.PERSONNEL RESPONSIBILITIES When working at an elevation of six (6) feet (1.8 meters) or more above grade, floor, or approved work surfaces such as platforms and scaffolds, or when working in an area where a fall potential of greater than six (6) feet (1.8 meters) exists, employees will utilize a full-body harness with a roper means of attachment.If traversing at an elevation, employees must be tied off at all times, which may require utilizing either two (2) independent shock-absorbing lanyards or a dual (Y) lanyard with a shock-absorbing device.FULL-BODY HARNESS All Contractors/Subcontractors will provide full-body harnesses meeting ANSI (American National Stand! ards Institute). Safety belts are NOT allowed for fall protection.Standard full-body harnesses are not designed for a combined personnel and tool weight in excess of three hundred (300) pounds (137 kilograms). Personnel weighing more than three hundred (300) pounds (137 kilograms), with tools, must consult the Project/Site Safety Representative prior to using fall-arresting equipment.LANYARDS Lanyards must meet the following requirements: Maximum length of a lanyard is six (6) feet (1.8 meters) in length, and it must be equipped with selflocking hooks on each end. The lanyard must be equipped with shock absorber. Snap hooks must be of a double-locking design to prevent accidental disengagement. When not in use, the lanyard must be secured and attached to the harness to prevent tripping or snagging. The lanyard must not be dragged. The lanyard must not be hooked back into itself unless designed for that purpose. Knots must not be tied in a lanyard. This will redu! ce the strength of the lanyard.ANCHOR POINTS Anchor points may! be an e xisting structure, a pipe, or a temporary or permanent engineered device such as an installed eyebolt, slide rail, or cable arrangement (e.g., static line). These anchor points must be inspected daily prior to use, by a qualified inspector. Engineered anchor points must be inspected by a competent person.Anchor points for lanyards/harnesses and vertical lifelines must meet the following requirements: be able to safely support one person falling six (6) feet (1.8 meters); be installed in a manner that prevents accidental disengagement from support structures; be inspected by a competent person on a periodic basis; be placed where attachment and detachment can be done without causing loss of balance; be placed above shoulder height to reduce fall distance; and be free of sharp edges to avoid cutting the lanyard.The following are examples of anchor points for individuals using harnesses, lanyards or vertical lifelines: Adequate For Use structural beams six (6) inc! hes (15.24 centimeters) or greater in depth for one (1) or more people; pipes four (4) inches (10.16 centimeters) or greater for one (1) person; pipes six (6) inches (15.24 centimeters) or greater for two (2) people; fixed permanent ladder rails and clips for one (1) person; permanent platform handrail post below midrail for one (1) person.Not Adequate For Use platform or scaffold handrails (except as noted above); scaffold ladders; conduit/instruments; any part of a valve; and ladder cages and rungs.HORIZONTAL AND VERTICAL LIFELINES Horizontal lifelines must be installed and used according to manufacturer's specifications. The following guidelines should also be followed: Softeners must be used where lifelines contact sharp edges, such as beam flanges. Temporary lifelines must be removed at the completion of a job. Anchor points, connectors, and other system components must be capable of safely supporting one (1) person falling six (6) feet (1.8 met! ers). A vertical lifeline shall be used by only one (1) pers! on at a time.NOTE!!! Horizontal and vertical lifelines must be inspected and maintained by a competent person on a daily basis.ROPE GRAB The rope grab must be used with a rope that meets or exceeds the following requirements: Rope grab size must match rope size; Minimum diameter of five-eighths (5/8) inch (1.59 centimeters) rope; Made of polypropylene, nylon, or polyester; Minimum tensile strength of five thousand (5,000) pounds (2,268 kilograms); and When rope grabs are used with wire rope, it must be a complete system. (Rope grab must be designed for a specific type and size of wire rope.)RETRACTABLE LIFELINES A retractable lifeline is a fall-arresting device used in conjunction with other components of a fall-arrest system. A retractable lifeline should be used by only one (1) person at a time.A properly inspected and maintained retractable lifeline, when correctly installed and used within the fall arrest system, automatically stops a person's descent a short distance ! after the onset of an accidental fall.Retractable lifelines should be considered for use when working in areas such as roofs and scaffolds, tanks, towers, vessels, and manholes. Also, retractable lifelines should be considered when climbing such equipment as vertical fixed ladders and telescoping derricks.Before using a retractable lifeline, the Supervisor and/or the user must address the following: Has the user been trained to use a retractable lifeline correctly? Is the retractable lifeline being used in conjunction with a complete fall-arrest system? Is the equipment under a regular maintenance program?Other considerations include: DO NOT USE ROPE. Attach self-retracting devices using shackles or carabiner. Equipment must be hung up or placed loosely in a clean, dry area when storing.FALL-ARRESTING EQUIPMENT INSPECTION Project/Site Management must ensure that documented monthly inspections are completed on all fallarresting equipment, including harnesses, lan! yards, lifelines, and anchor points.The inspector shall comple! te Form S31-2, Fall-Arresting Equipment Inspection Report, and forward the completed form to the Project/Site Safety Office or the designated person.Prior to each use, a visual inspection shall be made of the safety harness, lifeline, and lanyard(s) by the employee who will be wearing and using the equipment.All components of a fall-protection system must be tagged and inspected on a determined frequency. For devices that require additional certification, the devices shall be returned to the manufacturer or designated representative at the specified intervals for certification. These inspections must be documented.If a fall should occur, Project/Site Management must perform the following: Remove affected fall-arresting equipment from service. Have the equipment inspected and approved by the manufacturer's representative, prior to returning the equipment to service.If the equipment is unfit for further use, cut up the equipment and discard.Inspections must be conducted in the fol! lowing manner: Webbing/Ropes/Harnesses/Lanyards/Cables These items must be checked for the following: Beginning at one end, six (6) inches (15.24 centimeters) to eight (8) inches (20.32 centimeters) of the harness/lanyard must be bent into a U-shape. This helps reveal worn, cut, frayed, burned, or damaged fibers. Both splices and all straps along the entire length must be checked. Webbing must be carefully checked at attachment points to buckles and "D" rings. The shock-absorbing section of the lanyard must be checked for ripped stitches. The harness/lanyard must be checked for broken/frayed strands.Buckles/"D" Rings/Connectors/Retractalock/Ropelock These items must be checked for the following: rough, sharp edges; corrosion; dents or distortion; and freely moving parts.NOTE!!! Also ensure that the clasp on the Ropelock or cable on the Retractalock stops with a quick pull.Snap Hooks (Gate Locking Keepers/Gate Keeper Spring/Connectors)These items must be chec! ked for the following: Snap hooks must be double-locking and! must mo ve freely. Snap hooks must be checked for gaps in closure, sharp edges, burrs, distortion, cracks, corroded surfaces, and pitted surfaces.Labels Each harness and lanyard must have a label that displays the manufacturing date. If the date is more than five (5) years from the current date, the harness or lanyard must be destroyed and a new one obtained.WORK PRACTICES The following are special requirements associated with working at elevated locations or while using fall arresting equipment: Workers must avoid climbing on equipment such as pumps, exchangers, valve hand wheels, transformers, electric motors, handrails, structures, or any other facilities not specifically designed for climbing. Climbing on conduit, cable trays, or other similar equipment is not permitted. Climbing of vertical beams is not permitted. Workers must not climb a ladder while another person is above or below on the same ladder. Fall protection shall be utilized consistent with the specific exem! ptions and clarifications listed in the Fall Hazard Management Requirements Guide.Charles Morrison, Certified Safety Professional has published several articles and has presented papers at professional safety conferences while he has worked for major oil & gas companies and has created his own company, Safety Consulting Services.
