Study Notes

Fall Hazards Overview

NIOSH: Stands for National Institute for Occupational Safety and Health.
OSHA Training Focus: Includes caught-in or -between, struck by, electrocution, and falls.
Fall-related Deaths: One-third of all fall-related deaths in construction incidents occur from roofs.

Types of Falls

Falls can happen from ground level, through floor or roof openings, on flat surfaces, or from elevated heights above 6 feet.
Major fall hazards in construction include roof edges, floor openings, and improper scaffold construction.

Hazard Analysis and Complacency

Theoretical hazard analysis can identify non-obvious hazards and those that require multiple events to occur.
Complacency is driven by repetitive tasks, uncorrected unsafe conditions, and lack of management oversight.

Safety Regulations and Requirements

BLS: Bureau of Labor Statistics, tracks work-related injuries and fatalities.
JHA: Job Hazard Analysis, a process to identify potential hazards in the workplace.
OSHA mandates fall protection for workers at heights above 6 feet, whether near an edge or in trenches.

Fall Protection Systems

Essential elements of roof fall protection include restricting access and training workers on fall hazard recognition.
Personal Fall Arrest Systems (PFAS) consist of three main components: anchor/anchorage connector, full body harness, and body hook.

Equipment Standards

Snap hooks must be locking and designed to prevent accidental opening.
D rings and snap hooks require a minimum tensile strength of 5,000 pounds.
Ladders must maintain a 4:1 ratio: for every 4 feet of height, 1 foot should be positioned away from the wall.

Ladder Safety

Maintain three points of contact while using ladders.
Secure ladders to fixed points when possible to enhance safety.
Training for ladder use is crucial to mitigate risks associated with improper use.

Scaffold Safety

Scaffold access includes ladders, stair towers, and ramps.
Guardrails on suspended scaffolds made after 2000 must be between 38-45 inches high with midrails.
A competent person must supervise scaffold erection, inspection, and compliance.

General Safety Guidelines

Inspect personal fall protection equipment regularly; if defects are found, remove it from service promptly.
Utilize correct ladders for the job and follow safe practices to avoid accidents.
Retractable lanyards limit fall distance, making them a preferred choice for fall protection.

Conclusion

Understanding and adhering to safety protocols and regulations can significantly reduce the risk of falls in construction and occupational settings.
