CSLB General Building (B) flashcards

Fall protection may not be required on low-slope roofs (slopes 4:12 or less) if work is not performed near an unprotected edge.

• Applies to low-slope roofs
• Slope less than or equal to 4:12
• Work must not be near an unprotected edge

Memory trick: Four-inch rise, twelve-inch run, safety's won!

Side rails of portable ladders used for access must extend at least 3 feet (0.91 meters) above the upper landing surface.

• Applies to portable ladders
• Used for access to an upper landing
• Minimum 3 feet extension

Memory trick: Three feet high, reach for the sky, safely you'll climb!

A means of egress (ladder, ramp, etc.) must be located within 25 feet (7.62 meters) of workers in trenches 4 feet (1.22 meters) or deeper.

• Applies to trenches 4 feet or deeper
• Means of egress required
• Maximum 25 feet horizontal distance

Memory trick: Twenty-five feet, quick retreat!

Cal/OSHA limits the distance between the front edge of a supported scaffold platform and the face of the work to a maximum of 14 inches.

• Maximum 14 inches.
• Prevents falls through the gap.
• Reduces risk of falling objects.
• Exceptions if guardrails or nets are used.

Memory trick: Scaffold Gap is 'Fourteen' inches, no more.

A project management technique used to analyze and represent the tasks involved in completing a project, identifying the 'critical path' of tasks that must be completed on time for the project to finish on schedule.

• Identifies the longest sequence of dependent activities.
• Helps determine the minimum project duration.
• Crucial for projects with complex interdependencies.

Memory trick: CPM charts the critical path to success.

A common architectural and plumbing symbol on blueprints representing a floor drain.

• Typically a circle with an 'X' through it.
• Often labeled 'FD' for clarity.
• Indicates a point where water drains from the floor surface.

Memory trick: Symbols on a map guide your build, like 'FD' for where water's spilled.

Cal/OSHA mandates conventional fall protection (guardrails, safety nets, PFAS) for fall hazards over 7.5 feet or roof slopes greater than 4:12.

• Conventional methods are preferred.
• PFAS is a common and effective method.
• Warning lines/safety monitors have limited application.

Memory trick: Fall protection is 'Guard-Net-Arrest' for serious falls.

Cal/OSHA requires spoil piles to be placed at least 2 feet back from the edge of an excavation to prevent material from falling into the trench and to avoid adding surcharge weight.

• Minimum 2 feet from trench edge.
• Prevents falling material.
• Reduces surcharge on trench walls.

Memory trick: Spoil piles need 'Two Feet' of space.

The official abbreviation for the California Building Code, which sets standards for construction in California.

• Mandatory for all construction in California.
• Based on the International Building Code (IBC).
• Includes state-specific amendments and local ordinances.

Memory trick: When 'CBC' appears, in California, the Building Code is what it steers.

A specific permit required for the installation, modification, or repair of fire sprinkler and other fire suppression systems.

• Issued by the local Fire Department or Fire Marshal.
• Distinct from general building or plumbing permits.
• Ensures compliance with fire safety codes and standards.

Memory trick: For fire safety, don't just build, get the 'Fire Permit' to be fulfilled!

A logical dependency where the successor activity cannot begin until the predecessor activity has completed.

• Most common type of dependency in construction scheduling.
• Ensures sequential order of tasks.
• Example: Foundation must finish before framing can start.

Memory trick: When one task must 'finish' for the next to 'start', that's the FS rule, right from the heart.

A building permit is required for most significant construction, alteration, or repair work that affects the structural integrity, occupancy, or safety of a building, often including related sub-permits.

• Required for structural changes, additions, major remodels.
• Includes mechanical, electrical, and plumbing (MEP) work.
• Ensures compliance with building codes and safety standards.

Memory trick: Big changes need a Big Permit.

Cal/OSHA's Hazard Communication Standard requires employers to inform employees about chemical hazards associated with non-routine tasks.

• Covers tasks not part of regular operations.
• Includes specific hazards and protective measures.
• Ensures comprehensive hazard awareness.

Memory trick: HCS is about 'Written-Labels-SDS-Train-NonRoutine'.

A logical relationship in project scheduling where a successor activity can only begin once its predecessor activity has been completed.

• Most common type of task dependency.
• Ensures sequential order of tasks.
• Example: Painting cannot start until drywall is finished.

Memory trick: Finish First, then Start Second (FFSS).

Determining the length of a common rafter using the roof's run and rise, forming a right triangle.

• Half the building width is the 'run' for one side of the roof.
• The 'rise' is calculated from the run and the roof pitch.
• Rafter length is the hypotenuse: sqrt(run² + rise²).
• This doesn't include overhang or ridge board deduction.

Memory trick: Run, rise, then hypotenuse, for rafter length, no excuse!

Supported scaffolds must be secured against swaying or tipping when their height exceeds four times their minimum base dimension.

• Applies to supported scaffolds
• Ratio is height to minimum base dimension
• Securing prevents swaying/tipping

Memory trick: Four-leaf clover for scaffold height, stability it will have.

The California Building Code (CBC) specifies minimum clear opening dimensions for attic access, particularly when mechanical equipment is present, to ensure serviceability.

• Minimum 22 inches by 30 inches.
• Must be large enough to remove largest piece of equipment.
• Required for maintenance and safety access.

Memory trick: 22 by 30, for the attic's HVAC entry.

For Type C soil, Cal/OSHA mandates a maximum allowable slope of 1.5 horizontal to 1 vertical (1.5:1 or 34 degrees from horizontal) for excavations.

• Type C soil is the least stable common soil type.
• Slope must not exceed 1.5:1 (34 degrees).
• This applies to trenches 5 feet or deeper, or when soil conditions warrant.

Memory trick: Alphabetical soils, increasing slope 'A-B-C' for decreasing stability.

Cal/OSHA requires that all scaffold planks be secured to prevent accidental displacement, regardless of scaffold type.

• Applies to all scaffold platforms.
• Prevents planks from shifting or falling.
• Ensures a stable working surface.

Memory trick: Planks must be 'Secured, Overhanging, and Strong'.

Under Cal/OSHA HCS, a hazardous material is any chemical that is a physical hazard or a health hazard.

• Physical hazards include flammables, explosives, oxidizers.
• Health hazards include carcinogens, irritants, toxins.
• The presence of an SDS alone does not define a hazardous material if no hazard exists.

Memory trick: Hazardous materials are 'Physical-Health' threats.

The Hazard Communication Standard primarily requires employers to have a written program, SDSs, labels/warnings, and employee training.

• Written Hazard Communication Program
• Safety Data Sheets (SDS)
• Container labels and other forms of warning
• Employee information and training

Memory trick: SDS, Labels, Training, Program – HazCom's main diagram!

On structural drawings, a wide-flange steel beam is commonly represented by an 'H' shaped cross-section.

• Also known as W-beam or I-beam.
• Used for structural support in buildings.
• Symbol resembles the beam's actual cross-section.

Memory trick: Heavy 'H' holds up the structure.

The section of the California Building Code that establishes requirements for safe exit paths from buildings during emergencies.

• Covers exit access, exits, and exit discharge.
• Includes requirements for exit signs, illumination, and emergency lighting.
• Critical for life safety in all building types.

Memory trick: Chapter 10 for exits, when you need to flee, safety first, for you and me!

A grease interceptor (also known as a grease trap) is a plumbing device designed to intercept most greases and solids before they enter a wastewater disposal system.

• Prevents fats, oils, and grease (FOG) from entering sewers.
• Required in commercial kitchens and food processing facilities.
• Protects public sewer lines from blockages.

Memory trick: Grease Interceptor: FOG Fights Back.

Cal/OSHA requires fall protection for employees on roofs with a fall distance of more than 7.5 feet or a slope greater than 4:12.

• Fall distance > 7.5 feet requires protection.
• Roof slope > 4:12 requires protection.
• Acceptable methods include guardrails, safety nets, or personal fall arrest systems.

Memory trick: Roofers need to 'See-7.5-Slope-4' to stay safe.

Cal/OSHA mandates that the height of a scaffold must not exceed four times its minimum base dimension unless it is tied off, guyed, or braced.

• Ratio is 4:1 (height:base).
• Applies to freestanding scaffolds.
• Tying off or guying allows greater heights.

Memory trick: Scaffold height is 'Four-Times-Base' for stability.

For large, open-span areas like gymnasiums, trusses (either wood or steel) are the most common and efficient structural members used to support roofs or floors without intermediate columns.

• Efficiently distribute loads over long distances.
• Lightweight compared to solid beams of similar span.
• Common in gymnasiums, auditoriums, and industrial buildings.

Memory trick: Truss's Triangles Tackle Tough Spans.

Estimating the number of plywood sheets needed involves calculating the total area to be covered and dividing it by the area of a single standard plywood sheet.

• Standard plywood sheets are typically 4 ft x 8 ft.
• Area = Length x Width.
• Always consider a waste factor in real-world applications.

Memory trick: Area first, then divide by sheet size, simple math, no fuss.

In structural steel beam designations like 'W12x26', the 'W' stands for 'Wide-flange shape', indicating a specific type of I-beam.

• Standardized by AISC (American Institute of Steel Construction).
• 'W' indicates a wide-flange beam.
• The first number (e.g., '12') is the nominal depth in inches.
• The second number (e.g., '26') is the weight per linear foot in pounds.

Memory trick: W for Wide, Number for Depth, Last for Weight, that's the steel beam's fate.

Estimating concrete volume involves calculating cubic feet, converting to cubic yards, and adding a waste factor (typically 5-10%) before rounding up to the nearest full yard for ordering.

• 1 cubic yard = 27 cubic feet
• Common waste factor: 5-10%
• Always round up to the nearest full cubic yard for ordering

Memory trick: Calculate, Convert, Cushion, Confirm!

Cal/OSHA requires portable ladders used to access an upper landing surface to extend a minimum of 3 feet above that surface.

• Applies to portable ladders accessing upper landings.
• Provides a secure handhold for mounting/dismounting.
• Essential for fall prevention.

Memory trick: Three feet high, so you don't fly!
