Section § 7250

Explanation

This law defines a 'building' as any steel-framed structure with multiple floors that is taller than two stories while it's being constructed.

As used in this article “building” means any multifloor structural steel framed building more than two stories high in the course of construction.

Section § 7251

Explanation

This law explains that specific construction rules apply to buildings with multiple levels or stories. However, these rules do not apply to steel-framed buildings with large open spaces, like those used for mills, gymnasiums, auditoriums, hangars, arenas, or stadiums.

As defined above, these provisions shall apply to buildings erected in tiers or stories and shall not apply to steel framed buildings having large open spans or areas such as, mill buildings, gymnasiums, auditoriums, hangars, arenas, or stadiums.

Section § 7252

Explanation

In any building, the derrick or working floor must be fully covered with a solid surface except where there are openings for access.

The derrick or working floor of every building shall be solidly decked over its entire surface except for access openings.

Section § 7253

Explanation

This law mandates that during construction work like erecting, riveting, bolting, welding, or painting of beams, a strong temporary floor must be installed within two floors below where the work is happening. If workers are at risk of falling for a short time, they must use safety belts as described in another section.

There shall be a tight and substantial temporary floor within two floors below and directly under that portion of each tier of beams on which erection, riveting, bolting, welding or painting is being done. For operations of short duration of exposure to falling, safety belts shall be required as set forth in Section 7265.

Section § 7254

Explanation

This law requires that temporary floors be made from wood planks that are thick and strong enough to safely support the weight of workers and materials. The planks must be at least two inches thick and should not be smoothed or reduced in size.

Temporary floors shall be wood planking of proper thickness, grade and span to carry the working load, but shall not be less than two inches thick, full size undressed.

Section § 7255

Explanation

This law requires that temporary flooring, like those used in construction projects, must be secured so they don't get moved or damaged by strong winds or other forces.

Provision shall be made to secure temporary flooring against displacement by strong winds or other forces.

Section § 7256

Explanation

Planks used in construction or scaffolding should extend at least 12 inches beyond the center of the supports at each end to ensure safety and stability.

Planks shall extend a minimum of 12 inches beyond centerline of their supports at each end.

Section § 7257

Explanation

This law requires that any gaps or holes near columns, where planks don’t fit snugly, must be covered using wire mesh or exterior-grade plywood. This helps to ensure safety by preventing objects or people from falling through these openings.

Wire mesh or plywood (exterior grade) shall be used to cover openings adjacent to columns where planks do not fit tightly.

Section § 7258

Explanation

If you're using metal decking instead of wooden planks, it needs to be just as strong and must be placed securely so it doesn't move.

Metal decking where used in lieu of wood planking shall be of equivalent strength and shall be laid tightly and secured to prevent movement.

Section § 7259

Explanation

When floor planks are taken out temporarily during work, they must be put back right after the work is done. If they aren't immediately replaced, the open space should be properly secured to prevent accidents.

Floor planks that are temporarily removed for any reason whatsoever shall be replaced as soon as work requiring their removal is completed or the open area shall be properly guarded.

Section § 7260

Explanation

This law requires that before any temporary floor planks are removed, supervisors must instruct employees on how to safely and properly carry out the task, including the correct order of steps to take.

Prior to removal of temporary floor plank, employees shall be instructed by assigned supervision the steps to be taken to perform the work safely and in proper sequence.

Section § 7261

Explanation

This law section requires that when workers are gathering and stacking temporary floor planks on a lower floor for use on an upper floor, they must remove the planks in a specific way. They should start from one end and move towards the last panel, ensuring they are always standing on a planked floor as they work.

When gathering and stacking temporary floor plank on a lower floor, in preparation for transferring such plank for use on an upper working floor, the steel erector’s personnel shall remove such plank successively, working toward the last panel of such floor, so that the work is always being done from the planked floor.

Section § 7262

Explanation

This law requires that when workers are involved in collecting and stacking temporary floor planks, they must wear safety belts connected to a secure lifeline. This ensures their protection while working at heights, using either a catenary line or another strong anchor point.

When gathering and stacking temporary floor planks from the last panel, the steel erector’s personnel assigned to such work shall be protected by safety belts with life lines attached to a catenary line or other substantial anchorage.

Section § 7263

Explanation

This law requires that when building a structure, the methods used for assembling it, like bolting or welding, must always keep the structure stable. It should not only bear its own weight but also support any equipment or external forces during construction.

The sequence of erection, bolting, temporary guying, riveting and welding shall be such as to maintain the stability of the structural frame at all times during construction. This applies to the dead weight of the structure, plus weight and working reactions of all construction equipment placed thereon plus any external forces that may be applied.

Section § 7264

Explanation

In construction projects where a building is being built in multiple sections, each separate section is considered its own distinct building.

Where a building is being constructed in sections, each section constitutes a building as defined in Section 7250.

Section § 7265

Explanation

This law requires the use of safety belts and nets as specified in the Construction Safety Orders, which are guidelines set by the Division of Occupational Safety and Health to ensure worker safety on construction sites.

Safety belts and nets shall be required in accordance with Article 24 (commencing with Section 1669) of subchapter 4 of Chapter 4 of Part 1 of Title 8 of the California Administrative Code, Construction Safety Orders of the Division of Occupational Safety and Health.

Section § 7266

Explanation

This law states that if you are doing any work or have assigned work to someone else, you must use the required safety planking or nets before starting. If you don't, it's considered a misdemeanor offense.

No person shall proceed with any work assigned to or undertaken by him, or require or permit any other person to proceed with work assigned to or undertaken by either, unless the planking or nets required by this article are in place. Violation of this section is a misdemeanor.

Section § 7267

Explanation

This law states that the Division of Occupational Safety and Health is responsible for making sure that the rules and regulations in this article are followed.

The Division of Occupational Safety and Health shall enforce this article.
