  • 1. Fall Protection for Construction A Survival Guide
  • 2. Statistics
    • Falls are the number one cause of fatalities in the construction industry.
    • 150-200 workers are killed each year and more than 100,000 injured as a result of falls.
    • Overall (including general industry) falls are the number two biggest cause of fatalities in the U.S. (motor vehicle accidents are number one).
  • 3. Statistics
    • Falls 33%
    • Struck By 18%
    • Electrical 17%
    • Caught In 18%
  • 4. Statistics
    • 40% of the fatalities were from heights over 40 feet
    • Most falls occur on scaffolds or roofs
    • 25% of fall fatalities were from heights of 11-20 feet
    • 25% of fall fatalities were from heights of 20-30 feet
  • 5. Most Frequently Cited Unprotected sides & edges - Fall protection Fall hazards training program Fall protection - Steep roofs Fall protection - Residential construction 6’ or more Fall protection - Roofing work on low-slope roofs
  • 6. Physics of a Fall
    • A body in motion (free fall) can cover vast distances in a short period of time. Consider this:
      • A body in free fall can travel 4 ft in 0.5 seconds
      • A body in free fall can travel 16 ft. in 1 second
      • A body in free fall can travel 64 ft. in 2 seconds
  • 7. Application of Regulations
    • Subpart M (1926.500) applies to fall protection during construction activities.
    • There are a few exceptions from this rule for the following activities:
      • Inspection
      • Investigation
      • Assessing conditions prior to or after the work is performed
  • 8. Application of Regulations
