8 /4 /201 5 https://www.osha.gov/Publications/3106.htm lFederal Regulations (CFR), Part 1926.700 through 706 -- sets forth requirements with which construction employers must comply to protect construct ion workers from accidents and injuries resulting from the premature removal of formwork, the failure to brace masonry walls, the failure to sup port precast panels, the inadvertent operation of equipment, and the failure to guard reinforcing steel. Subpart Q prescribes performance-oriented requirements designed to help protect all construction workers from the hazards assoc iated with concre te and masonry construction operations at construction, de molition, alteration, or repair worksites. Other relevant provisions in both general industry and construction standards (29 CFR Parts 1910 and 1926) also apply to these operations. What Are the Key, New Changes to the Standard? OSHA's concrete and masonry standard in cludes the following important changes:

◾ Expands and toughens protection against masonry wall collapses byrequiring bracing and a limited access zone prior to the cons truction of a wall;

◾ Permits employers to use several more recently developed methods of testing concrete instead of just the one currently recogniz ed method; and

◾ Sets and clarifies requirements for both cast-in-plac e concrete and precast concrete during construction. What Are the Components of the New Standard? Subpart Q is divided into the following major groups each of wh ich is discussed in more detail in the following paragraphs:

◾ Scope, application, and definitions (29 CFR 1926.700);

◾ General requirements (29 CFR 1926.702);

◾ Equipment and tools (29 CFR 1926.702);

◾ Cast-in-place concrete (20 CFR 1926.703);

◾ Precast concrete (29 CFR 1926.704);

◾ Lift-slab construction (29 CFR 1926.705); and

◾ Masonry construction (29 CFR 1926.706). What Are the General Requirements of the Standard? Construction Loads Employers must not place construction loads on a concrete structure or portion of a concrete structure unless the employer dete rmines, based on information received from a person who is qualified in structural desi gn, that the structure or portion of the st ructure is capable of supporting the inten ded loads. Reinforcing Steel All protruding reinforcing steel, onto and into which employees could fall, must be guarded to eliminate the hazard of impaleme nt. Post-Tensioning Operations Employees (except those essential to the post-tensioning operations ) must not be permitted to be behind the jack during tension ing operations. Signs and barriers must be erected to limit employee access to the post-tensioning area du ring tensioning operations. Concrete Buckets Employees must not be permitted to ride concrete buckets. Working Under Loads Employees must not be permitted to work under concrete buckets while the buckets are being elevated or lowered into position. To the extent practicable, elevated concrete buckets must be routed so that no employee or the fewest employees possible are ex posed to the hazards a ssociated with falling concrete buckets. Personal Protective Equipment Employees must not be permitted to apply a cement, sand, and wa ter mixture through a pneumatic hose unless they are wearing pro tective head and face equipment. Equipment and Tools The standard also includes requirements for the following equipment and operations:

◾ Bulk cement storage,

◾ Concrete mixers,

◾ Power concrete trowels,

◾ Concrete buggies,

◾ Concrete pumping systems,

◾ Concrete buckets,

◾ Tremies,

◾ Bull floats,

◾ Masonry saws, and

◾ Lockout/tagout procedures. What Are the Requirements for Cast-in-Place Concrete? General Requirements for Formwork Formwork must be designed, fabricated, erected, supported, braced , and maintained so that it will be capable of supporting with out failure all vertical and lateral loads that might be applied to the formwork. As indica ted in the Appendix to the standard, formwo rk that is designed, fabricated, erected, supported, braced, and maintained in conformance with Sections 6 and 7 of the American National Standard for Construction and Demolition Operations -- Concrete and Masonry Work (ANSI) A10.9-1983 also meets the requirements of this paragraph. Drawings or Plans Drawings and plans, including all revisions for the jack layout, formwork (including shoring equipment), working decks, and sca ffolds, must be available at the jobsite. Shoring and Reshoring All shoring equipment (including equipment used in reshoring operations) must be inspected prior to erection to determine that the equipment meets the requirements specified in the formwork drawings. Damaged shoring equipment must not be used for shoring. Erected shoring equipment must be inspected immediately prior to, durin g, and immediately after concrete placement. Shoring equipment that is found to be damaged or weakened after erection must be immediately reinforced. The sills for shoring must be sound, rigid, and capable of carryi ng the maximum intended load. All base plates, shore heads, extension devices, and adjustment screws must be in firm contact and secured, when ne cessary, with the fo undation and the form.

8 /4 /201 5 https://www.osha.gov/Publications/3106.htm lEccentric loads on shore heads must be prohibited unle ss these members have been designed for such loading. If single-post shores are used on e on top of another (tiered), then additional sh oring requirements must be met. The shores must be as follows:

◾ Designed by a qualified designer and the erected shoring must be inspected by an engineer qu alified in structural design,

◾ Vertically aligned,

◾ Spliced to prevent misalignment, and

◾ Adequately braced in two mutually perpendicular directions at the splice level. Each tier also must be diagonally braced in the same two directions. Adjustment of single-post shores to raise formwork must not be made after the placement of concrete. Reshoring must be erected, as the original forms and shores are removed, whenever the concrete is required to support loads in excess of its capacity. Vertical Slip Forms The steel rods or pipes on which jacks clim b or by which the forms are lifted must be (1) specifically designed for that purpos e and (2) adequately braced where not encased in concrete. Forms must be designed to prevent excessive distortion of the structure during the jacking operation. Jacks and ve rtical supports must be positioned in such a manner that the loads donot exceed the rated capacity of the jacks. The jacks or other lifting devices must be provided with mechan ical dogs or other automatic holding devices to support the slip forms whenever failure of the power supply or lifting mechanisms occurs. The form structure must be maintained within all design tolerances specified for plumbness during the jacking operation. The predetermined safe rate of lift must not be exceeded. All vertical slip forms must be provided with scaffolds or work platforms where employees are required to work or pass. Reinforcing Steel Reinforcing steel for walls, piers, columns, and similar vertical structures must be adequately supported to pr event overturnin g and collapse. Employers must take measures to prevent unro lled wire mesh from recoiling. Such meas ures may include, but are not limited to, s ecuring each end of the roll or turning over the roll. Removal of Formwork Forms and shores (except those that are used for slabs on grade and slip forms) must not be removed until the employer determin es that the concrete has gained sufficient strength to support its weight and superimposed loads. Such dete rmination must be based on compli ance with one of the following :

◾ The plans and specifications stipulate conditions for removal of forms and shores, and such conditions have been followed, or

◾ The concrete has been properly tested with an appropriate Americ an Society for Testing and Materials (ASTM) standard test metho d designed to indicate the concrete

compressive strength, and the test results in dicate that the concrete has gained suffi cient strength to support its weight and superimposed loads. Reshoring must not be removed un til the concrete being supported has attained adeq uate strength to support its weight and all l oads placed upon it. Precast Concrete Precast concrete wall units, structural framing, and tilt-up wall panels must be adequately supported to prevent overturning an d to prevent collapse until permanent connections are completed. Lifting inserts that are embedded or otherwis e attached to tilt-up wall panels must becapable of supporting at least two timesthe maximum intended load applied or transmitted to them; lifting inserts for other precast members mustbe capable of supporting four times the load. Lifting hardw are shall be capable of supporting at least five times the maximum intended load applied or transmitted to the lifting hardware. Only essential employees are permitted under precast conc rete that is being lifted or tilted into position. Lift-Slab Operations

◾ Lift-slab operations must be designed and planned by a registered professional engineer who has experience in lift-slab constru ction. Such plans and designs must be

implemented by the employer and must include detailed instructions and sketches indicating the prescribed method of erection. T he plans and designs must also include provisions for ensuring lateral stability of the building/structure during construction.

◾ Jacking equipment must be marked with the manufacturer's rated ca pacity and must be capable of supporting at least two and one- half times the load being lifted

during jacking operations and the equipment must not be overloaded. For the purpose of this provision, jacking equipment includ es any load bearing component that is used to carry out the lifting operation(s). Such equipment includ es, but is not limited to, the following: threaded rods, lifti ng attachments, lifting nuts, hook-up collars, T-caps, shearheads, columns, and footings.

◾ Jacks/lifting units must be designed and inst alled so that they will neither lift nor continue to lift when loaded in excess of their rated capacity; and jacks/lifting units must have a safety device which will cause the jacks/lifting unitsto support the load at any po sition in the event of their ma lfunction or loss of ability to continue to lift.

◾ No employee, except those essential to the jacking operation, sh all be permitted in the building /structure while any jacking op eration is taking place unless the

building/structure has been reinforced sufficiently to ensure its integrity during erection. Th e phrase "reinforced sufficientl y to ensure its integrity" as used in this paragraph means that a registered professional engineer, independ ent of the engineer who designed and planned the lifting opera tion, has determined from the plans that if there is a loss of support at any jack location, that lo ss will be confined to that loca tion and the structure as a who le will remain stable.

◾ Under no circumstances shall any employee who is not essential to the jacking operation be perm itted immediately beneath a slab while it is being lifted. Masonry Construction Whenever a masonry wall is bein g constructed, employers must establish a limited access zone prior to the start of construction . The limited access zone must be as follows:

◾ Equal to the height of the wall to be co nstructed plus 4 feet (1.2 meters), and shall run the entire length of the wall;

◾ On the side of the wall that will be unscaffolded;

◾ Restricted to entry only by employees acti vely engaged in constructing the wall; and

◾ Kept in place until the wall is adequatelysupported to prevent overturning and collap se unless the height of the wall is more than 8 feet (2.4 meters) and unsupported,

in which case it must be braced. The bracing must remain in pl ace until permanent supporting elements of the structure are in p lace. What Other Help Can OSHA Provide? Safety and Health Program Management Guidelines Effective management of worker safety and he alth protection is a decisive factor in re ducing the extent and severity of workrel ated injuries and illnesses and their related costs. To assist employers and employees in developing effe ctive safety and health programs, OSHA published recommended Safety and Health Program Management Guidelines (Federal Register 54(18):3908-3916, January 26, 1989). These voluntary guidelines apply to all places of employment covered by OSHA. The guidelines identify four general elements that are critical to the development of a successf ul safety and health management program:

◾ management commitment and employee involvement,

◾ worksite analysis, 

# Page 3 of 9 Concrete and Masonry Constructio n

8 /4 /201 5 https://www.osha.gov/Publications/3106.htm l◾ hazard prevention and control, and

◾ safety and health training. The guidelines recommend specific actions under each of these general elements to achieve an effective safety and health progra m. A single free copy of the guidelines can be obtained from the U.S. Department of Labor, OSHA/OICA Publications, P.O. Box 37535, Washington, DC 20013-7535, by sending a sel f-addressed mailing label with your request. State Programs The Occupational Safety and Health Act of 1970 encourages states to develop and operate their own job safety and health plans. States administering occupational safe ty and health programs through plans approved under section 18(b) of the Act, must adopt stan dards and enforce requirements that are " at least as effective" as federal requirements. There are currently 25 State Plan states: 23 cover the private and public sector (state and local governments) an d 2 cover the public sector only. For more information on state plans, see the list of states with approved plans at the end of this publication. Free Onsite Consultation Consultation assistance is available on re quest to employers who want help in establ ishing and maintaining a safe and healthful workplace. Largely funded by OSHA, the service is provided at no cost to the employer. Primarily developed for smaller employers with more hazardous operations, the c onsultation service is delivered by state government agencies or universities employing professional safe ty consultants and health consul tants. Comprehensive assistance includes an appraisal of all work practices and environmental hazards of the workpl ace and all aspects of the employer's present job safety and health program. The program is separate from OSHA's inspecti on efforts. No penalties are proposed or citations issued for an y safety or health problems identified by the consultant. The service is confidential. For more information concerning consultation assistance, see the list of consultation projects at the end of this publication. Voluntary Protection Programs (VPPs) Voluntary Protection Programs (VPPs) and onsite consultation services, when coupled with an effective enforcement program, expa nd worker protection to help meet the goals of the Act . The three VPPs -- Star, Merit, and Demonstration -- are designed to recognize outstanding achiev ement by companies that have successfully incorporated comprehensive safety and health programs in to their total management system. They moti vate others to achieve excellent safety a nd health results in the same outstanding way as they establish a cooperative relation ship among employers, employees, and OSHA. For additional information on VPPs and how to apply, contact the OSHA area or regional offices listed at the end of this public ation. Training and Education OSHA area offices offer a variety of info rmation services, such as publications, audiovisual aids, technical advice, and speake rs for special engagements. The OSHA Training Institute in Des Plaines, IL, provides basic and advanced course s in safety and health for federal and state compliance officer s, state consultants, federal agency personnel, and private sector employers, employees, and their representatives. OSHA also provides funds to nonprofit orga nizations, through grants to conduct workpl ace training and education in subjects whe re OSHA believes there is a lack of workplace training. Grants are awarded annually and grant recipients are expected to contribu te 20 percent of the total grant cost. For more information on grants, training, an d education, contact the OSHA Training Inst itute, Office of Training and Education, 1555 Times Drive, Des Plaines, IL 60018; telephone: (847) 297-4810.
