This is for several reasons, but one main reason is so that small items like wrenches, wall ties, jointers, etc. Another item that should be noted is that you never increase the scaffold height by adding boxes, barrels, concrete block, brick etc… to the platform. Supports must bear on base-plates, mudsills, soleplates, or other adequate firm foundation as well as be level and plumb. scaffold shall be protected by both a personal fall arrest system and a guardrail. 22.B.14 Working levels of work platforms shall be fully planked or decked. A red tag makes it clear that nobody can occupy the scaffold because it’s not ready for use, or because there’s a problem with it (or the environment). That height for the first rung is actually quite high, and most people prefer sitting the ladder on the ground so they’re not required to have such a tall first step. There are many different foundations out there; there could be dirt, rock, mud, water, asphalt, grass, a roof, a metal top to a tank or concrete. This requirement is frequently neglected on movable scaffolding. It is suggested many times that a screw jack can only be raised 12 inches. Another not so commonly-known allowance is that a cross brace can be used for a mid-rail if the crossing point of the brace is between 20 and 30 inches above the platform and the ends of the cross brace are no more than 48 inches apart. This is a common question that many people don’t actually know the answer to. One way to enhance the safety of scaffolds is to consider the need for scaffolding when staging construction projects. However, pouring sidewalks, slabs, and other elements early in the project means that you’ll have solid, level surfaces for scaffolds. will not fall through the gap and strike someone below. About 2.3 million construction workers frequently work on scaffolds. Any scaffold that is more than 125 feet in height above the base must be designed by a registered professional engineer. In the introductory text to §1926.451(c)(2), the revised standard requires base plates (and mud sills or other adequate firm foundation) at all times now for support scaffold poles, legs, posts, frames, and uprights. Finally, weather conditions can create or contribute to hazards. Inspect and inspect again Simply put, nobody should be able to set foot on any part of a scaffold without proper training. Construction sites are places of constant change. To ensure stability for more complex scaffolds, drawings should be produced and, where necessary, these may need to be supplemented with specific instructions. 1926.451(c)(2) An additional fact that all of our readers should know is that the out-rigger scaffold is supposed to be a maximum of 3 inches away from the wall. Scaffold 0c8be2a1 9996-490a-99c0-6ef40baed98a 1. Even with a base plate or screw jack, it also needs a wooden mud sill if it’s going to be setting on dirt, gravel, grass etc. This includes ladders, such as extension ladders or step ladders. Overhead equipment poses a hazard for head injuries. Again, it’s for more than one reason, but the main one is because there are no handrails next to your out-rigger facing the masonry wall that you’re working on, therefore they want the wall in front of you and less chance of falling on that side the scaffold. Every system must include a top rail and mid rail. Although they may not get the attention they deserve from the workers who use them, the people who are responsible for those workers’ safety recognize the danger. a. But the more important reason is to ensure their safety. Each scaffolding system is engineered differently. Scaffolds can be built on catwalks, on the space shuttle and anything else that someone may have to work on. As many as 50 workers actually die. Even if the scaffold is only out of level by a very small amount, it is not considered safe. Supported scaffold poles must bear on firm … OSHA rules prohibit using the scaffold’s bracing as a point of access or ascent. as a midrail, it must be between 20 inches (0.5 meters) and 30 inches (0.8 m) above the work platform. We tend to think of scaffolds as simple structures, but they actually depend upon complex engineering and the balancing of different forces. They are the platforms and climbing devices we describe as scaffolding. Have You Fallen for These Common Safety Myths? Another thing that should always be maintained is the proper height of the top rail. Scaffolding. such as tie-ins, as the assembly progresses. For scaffolds that fall outside the scope of a generally recognised standard configuration the design must be such that safe erection and dismantling techniques can also be employed throughout the duration of the works. by rigid triangular bracing or equivalent – bottom, top, and other points as necessary. Scaffolds shall bear on adequate firm foundations such as: a. boxes, barrels b. bricks @base plates set on mudsills d. loose materials piled high enough to achieve level 20. That isn’t the case. Another interesting tidbit about platform construction is that one scaffold board is not permissible to work from. Employers must provide proper training, which must encompass subjects such as fall hazards, falling object hazards, electrical hazards and handing of materials before putting people to work on supported scaffolds. For example, the scaffold legs cannot be placed on a mud foundation without a base to prevent the legs from sinking into the mud." You must check with the manufacturer of the screw jack that you are specifically using. Safety Management Group offers a full complement of state-of-the-art services delivered through a wide variety of channels addressing industry specific issues. Subscribe to our newsletter and stay informed. An adequate foundation is one that, like base plates on mud sills, will prevent the scaffold from settling into the ground. If the scaffold needs to be tied into the structure, proper procedures must be followed. Ask us about our NEW state-of-the art mobile training. Protecting these workers from scaffold-related accidents would prevent an estimated 4,500 injuries and 50 fatalities each year. 22.B.12 Scaffolds shall be plumb and level unless engineered and designed to contour as the structure does. In other words, you can’t take a frame scaffold and just set it on the ground or even on concrete. Depending on the specific condition of the surface, that may include the use of mud sills or base plates. Also, if it is a scaffold board greater than 10 feet, you can have no more than 18 inches over its hand support or there must be guardrails so that someone cannot walk out on the end of those cantilevered boards, they tip up and a person falls. Scaffolds must bear on base plates or screwjacks on a mud sill or other adequate firm foundation. Concrete is the lone exception to this rule, which, because of its structural properties and strength, … Under safety regulations, a competent person is responsible for overseeing and coordinating all aspects of scaffolding. At the beginning of each shift, a competent person inspects the scaffold and attaches one of three tags. Every scaffold must be absolutely level. OSHA gives a little leeway in the top rail; it can be between 38 and 45 inches in height. Scaffolds must always be set on a firm foundation, so if the surface below the legs doesn’t offer sufficient strength to withstand the weight and stress, steps must be taken to compensate. Now, hopefully you already knew all of this, but as you know, the three steps to remembering are Repetition, Repetition, Repetition! One thing that I often see and I’m sure not as many people know as there should be, is that there is only supposed to be 1 inch or less gap between scaffold boards. Competent Persons can have other duties, such as working on the scaffold or other supervisory duties and verification of fall arrest anchor points. That is why hazard analysis needs to be an ongoing process. Supported scaffold poles, legs, posts, frames, and uprights shall bear on base plates and mud sills (or other adequate firm foundation). (2) Every scaffold shall be constructed, erected or installed on structures or foundations of adequate strength. Where materials other than wood are used or where scaffold designs differ from those specified in these Orders, the scaffold and its parts must provide a degree of strength, rigidity and safety equivalent to that provided by the described scaffold it replaces. If the elevation difference between a scaffold and an adjacent surface is greater than 24 inches, a ladder or a step must be used. This is actually not correct. Learn More, By Jordan Hollingsworth, MS, ASP, CHST, CHSP, CRIS® Any scaffold that requires someone to step up more than 24 inches should have a ladder utilized to access the scaffold. Prot\൥cting these workers from scaffold-related accidents would prevent 4,500 injuries and 50 deaths every year, at a saving for Ame對rican employers of $90 million dollars in workdays not lost. It’s common for workers to believe that simply adjusting the legs to the right height will prevent problems from occurring, but the bigger issue is what is supporting those legs. Scaffolds have been used for tissue engineering such as bone, cartilage, ligament, skin, vascular tissues, neural tissues, and skeletal muscle and as vehicle for the controlled delivery of drugs, proteins, and DNA. Here at SoCal Removal we have implement a stringent policy to ensure that employees are not exposed to hazards while working on or with scaffolding or elevated work platforms. Supported scaffolds must bear on base plates and mud sills or other adequate firm foundation. They should be taught to look around to identify adjacent hazards, such as moving equipment, electrical wires, or hot pipes. That brings us to screw jack height. Typically, the biggest hazard is falls, which explains the rationale for requiring guardrails or some type of fall-protection equipment on scaffolds that are at least ten feet above the ground or next level. 1926.451(g)(1) • Guardrail height—The height of the toprail for scaffolds manufactured and placed in service after January 1, 2000 must be between 38 inches (0.9 meters) and 45 inches (1.2 meters). A yellow tag sends the message that the workers can use the scaffold only under certain conditions. • Ensuring that a tag is placed on scaffold indicating its current condition (i.e. Particularly brave –and trained – employees may use stilts on a large, supported scaffold, provided the guardrail height is adjusted to compensate. structure. Workers should be familiar with load ratings, and how those ratings might affect a particular task (such as whether the scaffold will safely accommodate a heavy piece of equipment along with their own weight). They should be installed on all open sides of the scaffold. Competent Persons shall be physically present at the scaffold during such work. When the scaffold is at a greater height, it will be leaning out of plum at a much greater degree. Andre Abajian or SoCal Removals designated competent scaffolding person is responsible for ensuring the following engineering controls, training requirements, and safe work practices are enforced to protect our employees from ha… © 2020 Masonry Magazine masonrymagazine.com All rights reserved. The first rung or bottom rung of the ladder must be a maximum of 24 inches from the ground or walking working surfaces. All wood planking shall be selected for scaffold plank use as recognized … Work Practices Safe work practice training by a Competent Person must be given to workers who erect, dismantle, move, operate, repair, maintain, inspect, and use scaffolding. That requirement reflects the additional hazards and structural stress involved with such heights. That’s important, because nearly 4,500 workers are injured each year in scaffold-related incidents. Any minor damage to those surfaces that is caused by the scaffolds is easy to repair, and the cost of those repairs is usually clearly offset by the time and trouble saved when erecting scaffolds — not to mention the substantially lower risk of injury resulting from a collapse. Depending on the specific condition of the surface, that may include the use of mud sills or base plates. 1926.451(c) Supported scaffolds (contd) Scaffold platforms must be fully planked ; 19 1926.451(c) Supported scaffolds (contd) Must bear on adequate foundations ; Unstable objects will not be used as working platforms ; Plumbed and braced ; 20 1926.451(d) Suspension scaffolds. Use and document a tagging system Typically, that is either a stair tower or a bolt-on ladder. • Providing adequate foundations, proper access, bracing, handrails and toeboards , and adequate decking materials. “It’s close enough.” There’s no such thing as close enough when it comes to getting the scaffold level. Prior to assembly, a qualified person must design the scaffold and set the specifications for using it. timber scaffolds must be rattan or such other material as approved in writing by the chief inspector. Besides meeting the legal requirements, having clear documentation will also help you deal with the insurance company if an incident occurs. Foundations. The inspection should include the work platform itself, as well as the integrity of the entire structure. In other words—they know all there is to know about scaffolds! Additionally, extreme weather conditions may rule out the use of an otherwise safe scaffold. Supported scaffolds with a height to base width ratio of more than 4:1 must be restrained by guying, tying, bracing, or an equivalent means. The competent person will confirm, based on the evaluation, that the supporting surfaces are capable of supporting the loads that will be imposed. • Scaffold poles, legs, posts, frames and uprights must bear on base plates or other adequate firm foundations. That’s especially true when workers are using metal strapping or tools in close proximity to the lines. Re … Numerous scaffolds produced from a variety of biomaterials and manufactured using a plethora of fabrication techniques have been used in the field in attempts to regenerate different tissues and organs in the body. • Providing direction to those employees who may be assisting them in the erecting or dismantling of a scaffold. Scaffolds must be exactly plum and exactly level for it to be considered safe. Because most scaffolds are constructed from metal components, contact with live power lines may create an electrocution hazard. Unless the manufacturer specifically indicates that the components are compatible and can work together, don’t mix them. If the structure of the scaffold or its surrounding area have been altered, or if weather conditions change, it should be re-inspected. Scaffolds can be built on catwalks, on the space shuttle and anything else that someone may have to work on. What I will try to do in this article is to address both things that are commonly found on any construction site and not so obscure that it would never be utilized. A couple of points about scaffold access. Words: Zach Everett, Corporate Safety Director Brazos Masonry Inc., Legacy Masonry Inc. That can lead to anything from a slightly unstable work surface to an actual collapse. Check the hazards at the beginning of every shift Cross braces will not go on as easily or at all, and if the scaffold is leaning out of plum and a load is set on top the chances of it overturning are dramatically higher. A Competent Person shall be available on site at any time scaffolding is in use in the event conditions change or the scaffolding is moved or modified. An “adequate foundation” is what OSHA says that every scaffold must have. Support devices must support 4 x imposed load With many projects, outdoor features such as sidewalks, driveways, and parking areas are often the last items to be constructed, because the architects and construction managers want to limit potential damage. (b) Scaffolds shall be constructed of wood or other suitable materials such as steel or aluminum members of known strength characteristics. The only foundation that does not need a mud sill is concrete. Kidde Recalls Fire Extinguishers with Plastic Handles Due to Failure to Discharge and Nozzle Detachment: One Death Reported, Partnership Renewed between Safety Management Group and the Indiana Manufacturers Assocoaition, Safety Management Group Awarded Wishard OCIP Safety Program Contract, Working safely around pressurized vessels doesn’t have to be a high-pressure task. An “adequate foundation” is what OSHA says that every scaffold must have. The size of the mud sill shall be based on the type of soil the scaffold will be erected upon.The base and mud sill must provide a solid surface for the feet to sit upon so that the scaffold doesn't sink, move, settle, or shift. Another thing that most people that are reading this are aware of is that the ladder must reach at least 3 feet above the scaffold platform. If the work environment involves multiple shifts, a competent person should conduct his or her own inspection for the benefit of the workers on that shift. Access to and from the scaffold can create its own set of hazards, because the potential for slips and falls increases as workers ascend or descend from the scaffold. “All I do is stand on the scaffold,” they’ll say. If he or she notices a yellow or red tag from the previous shift, that person should determine whether the tag is still needed. Here’s one that you may not know; if a board is 10-foot-long or less you cannot have more than 12 inches of the end of the board over it support. Any bracing must be properly secured to ensure that it will not become loose once under stress. Going beyond that limit – even for a task that takes just a few minutes – is inviting trouble. Under construction, damaged) . That’s why the companies that design and build them invest so heavily in engineering – and why it’s so important to ensure that the people entrusted to oversee them on jobsites receive adequate training. Simply tying the scaffold in place with wire may be an accepted practice among workers, but it violates OSHA regulations. Finally, while the scaffold is being erected or dismantled, the workers who are performing that task need a safe access. 22.B.14 Working levels of work platforms shall be fully planked or decked. OSHA 10-Hour Construction Course: Module 5 – Scaffolds Page 1 of 22OSHA MODULE 5 – ScaffoldsLearning ObjectivesUpon completion of the lesson, participants will be able to: • Name the three types of scaffolds and describe their main characteristics • List at least three of the four main hazards to which persons working on a scaffold … (4) In the case of a scaffold exceeding 15m in height or being erected on poorly drained soil, base plates shall bear upon sole plates that are — When scaffold platforms are more than 2 feet above or below a point of access, access is required to be provided. Base plates are required at a minimum. Mudsills are also required unless on an adequate firm foundation (such as a concrete floor). “Why do I need to be trained for that?”. https://quizlet.com/168676654/cfm-345-test-2-part-3-flash-cards For example, the competent person has to decide whether the workers who are assembling or dismantling the scaffold will need fall protection while performing those tasks. If the scaffold includes stair-type ladders, they should include handrails, rest platforms, and treads to reduce the possibility of slipping. Because the most common on construction sites and in manufacturing applications is the fabricated modular frame type that can be assembled into a variety of configurations for different heights and tasks, this article will focus on that type. Supported scaffolds' poles, legs, posts, frames, and uprights must bear on base plates and mud sills, or other adequate firm foundation. The term “little known,” is subjective at best. Pump Jack Scaffold. All footings must be level, sound, rigid, and capable of supporting the scaffold without settling. A firm foundation, such as a flat, level concrete slab, is an adequate surface for a base plate. (3) Where a scaffold is to be founded on soil, the soil shall be adequately consolidated. While they may be ordinary and utilitarian, they tend to fail in dramatic, newsworthy ways. Workers who are accustomed to scrambling up the side braces during assembly are often surprised by (and resistant to) that requirement. Designed and built by, Our core values, mission, and commitments, IOSHA Revises Residential Fall Protection Program, Grain-handling Presents a Variety of Safety Hazards, Improving Contractor Interactions Through the SCARF Model, Components You Need for an Effective ILSM Program, Understanding Ground Fault Circuit Interrupters. Pole or Wood Pole. Read and follow all directions However, most of the concepts and counsel incorporated here also applies to other types. Every other foundation must have a base plate or screw jack and mud sill. The standard recognizes that certain foundations may be of adequate firmness to support a scaffold without the use of mud sills. Interchanging components from other systems or manufacturers may look safe, but it also may compromise the scaffold’s structural integrity. Training: the critical first step Failure to do so makes the scaffold less stable and, while it may not topple, it may sway or move enough to knock someone off the platform. A qualified person has the right background such as education, degree, certification or professional standing that shows they are an expert in designing safe scaffolding. Safety Advisor, Design and Construction. Some are designed to be raised 18 inches and many have a notch or a weld towards the top of the jack which is its maximum raising height and prohibits you from screwing the Jack any higher past that notch. (1926.451(c)(2)) Adequate Foundation. OSHA does allow a ladder to be used on top of the scaffold if many stipulations are met, but this is not a suggested practice. 22.B.15 Planking. Any bracing must be properly secured to ensure that it will not become loose once under stress. A rule of thumb is that scaffolds will become unstable once the overall height reaches four times the length of the shortest part of the base. That includes workers who perform their tasks on or from the scaffold, as well as those who use scaffolding as a means to get to their own worksites. Poles must be secured to . OSHA regulations state that any scaffold must be at least 18 inches wide. They need to be cognizant of fall-protection requirements and other safety features such as toe boards. Regulation 10(2): Work platforms must be provided at intervals of not more than 4 metres for the entire length of the scaffold. This happens more often when platforms are only one or two planks wide and guardrails are missing, as is often the case during erection and dismantling. A green tag signifies that the scaffold has been inspected and is safe for use. There are many different foundations out there; there could be dirt, rock, mud, water, asphalt, grass, a roof, a metal top to a tank or concrete. In addition, scaffolding hazards vary with the nature of the tasks being performed and the operating environment. Ladder jacks must be designed and constructed to bear on the side rails and ladder rungs. 22. Unstable objects, such as bricks, cinder blocks, buckets, scrap lumber, etc., shall not be used to support or level scaffolds. These injuries account for nearly 50 deaths and thousands of injuries each year in the United States alone. Scaffolds seem to be fairly simple structures, and it’s not unusual for workers to start slapping them together without any extra thought, assuming that all systems and applications are exactly the same. Supported scaffolds are required to be plumb and braced. There may be exceptions if there was absolutely no other way to errect the scaffold, but you must be able to prove that. Above all: respect scaffolding The top rail should be able to withstand 200 pounds of downward and outward force placed upon it. Icicles that form on portions of the structure above the scaffold may thaw and suddenly drop on workers. scaffolding or scaffolds must ensure, so far as is reasonably practicable, all workplace activity relating to the plant or structure including its decommissioning or dismantling is without risks to health or safety. Ladders used to support ladder jack scaffolds must be placed to prevent slipping fastened to prevent slipping and or equipped with devices to prevent slipping. A scaffold that was safe a month ago may have become unsafe because of something that was constructed nearby, or because of a task that is now being performed in an adjacent area. Some workers will react to that concept with surprise, or even contempt. It isn’t that scaffolds are any more or less inherently dangerous than other aspects of worksites. They reach to impressive heights, but far too little attention is paid to their connections to the ground. Supported scaffold poles, legs, posts, frames, and uprights shall bear on base plates and mud sills or other adequate firm foundation. Regulation 20(4): Every lift of a scaffold must be crossed by at least one longitudinal bracing member in every 10-metre length of the scaffold. Note that the list includes workers who “use” scaffolding. In closing we cannot talk about safe scaffolding without bringing up the guardrail system. It must have a base plate or screw jack at a minimum. The legs, poles, frames, and uprights shall bear on base plates and mud sills. Copyright ©2020 Safety Management Group. The other type of training is referred to as Competent Person training. B.13 Scaffolds (other than suspended scaffolds) shall bear on base plates upon mudsills or other adequate firm foundation. An estimated 2.3 million construction workers, or 65 percent of the construction industry, work on scaffolds frequently. Guardrail system. D. Suspension Scaffolds • Before a scaffold is used, the competent person shall evaluate all direct connections. (2) You must make sure supported scaffold poles, legs, posts, frames, and uprights, bear on base plates that rest on: (a) Mudsills; or (b) Other firm foundations such as concrete or dry, compacted soil. Scaffolds must always be set on a firm foundation, so if the surface below the legs doesn’t offer sufficient strength to withstand the weight and stress, steps must be taken to compensate. When performing those inspections, focus on the tasks that will be performed that day, and verify that the scaffold will provide a safe platform. “Scaffolding” is a broad term that covers many different types of platforms and systems. Cross braces must not be used as a means of access. B.13 Scaffolds (other than suspended scaffolds) shall bear on base plates upon mudsills or other adequate firm foundation. Scaffolds must be inspected at least once a day by a competent person. In OSHA’s eyes, if you fail to document that you performed the inspection and placed the tag, that never took place. a. No wonder OSHA puts such a strong focus on scaffold safety, with their inspectors making scaffold flaws one of their most-cited violations. 1926.451(g)(4) • Footings—Support scaffold footings shall be level and capable of supporting the loaded scaffold. Officers. HomeArticlesAdvertiseSubscribeVideosContactTerms of ServicePrivacy Policy, Mason Contractors Association of America1481 Merchant DriveAlgonquin, IL 60102, Phone: 800-536-2225 | 224-678-9709Fax: 224-678-9714. A platform that becomes wet or icy creates a risk for skips and falls. Regardless of the tissue type, a number of key considerations are important when designing or determining the suitability of a scaffold for use in tissue engineering: (i)BiocompatibilityThe very first criterion of any scaffold for tissue engineering is that it must be biocompatible; cells must adhere, funct… However, that rule applies only when the scaffold has been properly assembled, has been set on the correct base, and is in plumb. They need to be made aware of correct use of the scaffold and how to handle materials and tools when working on it. In this Guide the scaffolding contractor is the person responsible for installing, constructing and commissioning scaffolds. Safety issues surrounding scaffolds tend to be the result of a lack of awareness of the hazards they present, along with a lack of familiarity with the procedures that will minimize risk. 22. Generally, the adequacy of a foundation to support a scaffold cannot be determined in the abstract because of the numerous factors which may exist at a work site. Each manufacturer designs his screw jack differently, and some design them so that they can be raised higher than 12 inches. For starters, any scaffold should have a base of some sort. 22.B.15 Planking. Walkways and work platforms shall be a minimum of 18 inches wide. 1926.451(c)(2)(i) and (ii) Restraining. 22.B.12 Scaffolds shall be plumb and level unless engineered and designed to contour as the structure does. They’re one of these most common features on construction sites and in industrial settings — and one of the most inherently dangerous. plus 4 times the applied or transmitted load on the scaffold without failure. Even the most carefully engineered and assembled scaffold will be unsafe if it doesn’t have a firm foundation. Placing the tag is only part of the process. Platform construction. By respecting that complexity and ensuring that all employees involved with their erection and use are properly supervised, supervisors will be able to reduce the number of injuries and equipment damage caused by scaffold-related incidents.
