    Study Notes

    Personal Fall Arrest System (PFAS)

    • PFAS consists of three components: anchor and anchorage connector; full body harness; and connecting device (e.g., lanyard with shock absorber).

    Scaffold Load Requirements

    • Supported scaffolds must bear their own weight plus at least four times the intended load without failure.

    Common Fall Hazards

    • Fatalities have resulted from falls to lower levels, through openings, on the same level, through roof surfaces, and all the above constitute serious job site fall hazards.

    Fall Protection Requirements

    • Fall protection is mandated for work over dangerous equipment and machinery, regardless of height.

    Equipment Inspection

    • Defective personal fall protection equipment must be removed immediately from service if found during inspections or after an arrest.

    Ladder Safety

    • Preventing falls from ladders includes choosing the correct ladder, securing it at the top and bottom when necessary, and avoiding carrying tools while climbing.

    Fatalities in Construction

    • Over one-third of fatalities in construction arise from falls, particularly from roofs.

    Fall Hazard Controls

    • Controls like guardrails, walls, protective covers, and parapets are essential for mitigating fall hazards.

    Scaffold Safety

    • Employees can work on scaffolds only after confirming the strength and structural integrity to support intended loads.

    Major Fall Hazards

    • Examples include roof edges, floor openings, improper scaffold construction, and unsafe ladder use; all are considered major fall hazards.

    Trench Safety

    • OSHA mandates fall protection for trench or excavation work that is six feet deep or more.

    Scaffold Use Guidelines

    • Climbing on scaffold cross braces is not permitted at any time.

    Lifeline Supervision

    • Horizontal lifelines must be installed under the supervision of a qualified person to ensure safety.

    Scaffold Safety Requirements

    • Safe access, full planking, stable footing, and guardrails are essential requirements for scaffold use.

    Connector Strength Standards

    • Snap-hooks and D-rings must have a minimum tensile strength of 5,000 pounds.

    NIOSH Definition

    • NIOSH stands for the National Institute for Occupational Safety and Health.

    OSHA's Focus Four

    • Training focuses on four main hazards: Caught-In or Between, Struck-By, Electrocution, and Falls.

    Hazard Definition

    • A hazard is any situation that could harm life, health, property, or the environment.

    Complacency in Safety

    • Complacency, a hazardous behavior, can stem from repetition, unresolved unsafe acts, and lack of management enforcement.

    Preventing Complacency

    • To prevent complacency, engage in hazard recognition planning, safety audits, and peer vigilance.

    Fall Incident Causes

    • Fall incidents occur when individuals underestimate gravity, neglect safety measures, or become complacent.

    Falling Speed

    • A person can fall 64 feet in approximately two seconds.

    Fall Hazard Definition

    • A fall hazard is a condition that can cause one to lose balance or bodily support.

    OSHA Fall Protection Requirements

    • OSHA requires fall protection for construction sites at six feet in height.

    Criteria for Fall Restraint Systems

    • Fall restraint systems must prevent reaching free fall areas, have sufficient anchorage strength, and be designed by qualified personnel.

    Scaffold Maintenance

    • Ice and snow must be cleared promptly from scaffolds to prevent slipping.

    Causes of Scaffold Failures

    • Common causes include unsafe erection, excessive weight, lack of oversight, and use of incompatible parts.

    Ladder Violations

    • Frequent ladder violations include failing to secure the ladder, inadequate training, and improper use of ladder top steps.

    Inspection Protocols for Scaffolds

    • Scaffolds must be visually inspected for structural integrity, proper components, and safety compliance.

    Guardrail Height Regulations

    • Guardrails on suspended scaffolds post-2000 must be 38 to 45 inches high, with mid-rails added for safety.

    Supported Scaffold Planking

    • Planks on scaffolds need to extend at least 6 inches but not more than 18 inches beyond supports.

    Safe Scaffold Practices

    • Ensure safe scaffolding practices include compliant access, full planking, stable footing, and effective fall protection.### Incident Investigation
    • The final step in conducting an incident investigation is to preserve and document the scene to capture critical evidence.

    Anchorage Points Requirements

    • Employers are required to identify and evaluate attachment points, ensure proper use of fall protection by workers, and educate workers on equipment inspection and donning.

    Scaffold User Training

    • Necessary training must cover hazards associated with the type of scaffold used, including maximum intended load and capacity.

    Competent Person Definition

    • A competent person is defined as someone who selects, directs, and inspects employees working with scaffolds to ensure compliance with safety standards.

    Lanyard Usage

    • One lanyard can only be utilized by a single worker for safety reasons.

    Horizontal Lifeline Design

    • Horizontal lifelines must maintain a safety factor of at least two times the maximum intended load and be supervised by a qualified individual.

    Deceleration Devices

    • A deceleration device is designed to manage fall arrest energies, mitigating the impact on an employee during a fall.

    Scaffold Safety Regulations

    • For scaffolds over 10 feet high, a guardrail system or personal fall arrest system is mandated for safety.

    Roof Access Control

    • A roof permit system is crucial for restricting roof access to authorized personnel only.

    Scaffold Safety Practices

    • Climbing on the cross braces of a scaffold is never allowed under any circumstances.

    Ladder Securing Best Practices

    • Ladders should be secured to fixed and secure points to enhance safety during use.

    Workplace Assessment

    • Employers are required to evaluate workplace conditions to ensure walking/working surfaces can support worker safety.

    Body Belt Regulations

    • Body belts are permissible for work positioning only, not for general fall protection.

    Significant Fall Hazards

    • Recognized significant fall hazards in construction include roof edges, floor openings, unsafe ladder use, and improper scaffold construction.

    Job Hazard Analysis (JHA)

    • Conducting a job hazard analysis enables systematic identification and evaluation of risks, focusing on how to control or mitigate all hazards identified.

    Fall Protection Standards

    • OSHA standards require fall protection in construction at heights of 6 feet or more.

    Fall Time Calculation

    • A person falls 64 feet in approximately 2 seconds, highlighting the rapid risk of serious injury.
