2. Most frequently cited fall protection standards
Unprotected sides & edges - Fall protection
Fall protection - Residential construction 6’ or more
Fall hazards training program
Fall protection - Roofing work on low-slope roofs
Fall protection – Steep roofs

3. Falls
Falls are the leading cause of fatalities in the construction industry
An average of 362 fatal falls occurred each year from 1995 to 1999, with the trend on the increase
It is important that safety and health programs contain provisions to protect workers from falls on the job
The following hazards cause the most fall-related injuries:

4. Am I in danger?
All sites have unprotected sides and edges, wall openings, or floor holes at some point during construction
If these sides and openings are not protected at your site, injuries from falls or falling objects may result
This worker is not protected by any of the protective
systems that are required by OSHA.

5. How do I avoid hazards?
Use at least one of the following whenever employees are exposed to a fall of 6 feet or more above a lower level:
Safety Net Systems
Guardrail Systems
Fall Arrest Systems

6. How do I avoid hazards (cont’d) ?
Cover or guard floor holes as soon as they’re created
Survey site on existing structures before working and continually audit as work continues
Floor hole covers must support two times the weight of employees, equipment, and materials
Better to use fall prevention systems, such as guardrails, than fall protection systems, such as safety nets or fall arrest devices
Better to use fall prevention systems, such as guardrails, than fall protection systems, such as safety nets or fall arrest devices, because they provide more positive safety means

7. `
Guardrail systems
Where workers on a construction site are exposed to vertical drops of 6 feet or more
Employers can provide fall protection in one of three ways before work begins:
Placing guardrails around the hazard area.
Deploying safety nets
Providing personal fall arrest systems for each employee
This guardrail appears to be properly
constructed except for the missing
toeboard that is required to prevent
object from falling to the floor below
and possibly striking another worker.
Many times the nature and location of the work will dictate the form that fall protection takes. If the employer chooses to use a guardrail system, he must comply with the following provisions:

8. Safety net systems
Safety nets must be installed as close as practicable under the surface on which employees are working, but in no case more than 30 feet below
When nets are used on bridges, the potential fall area must be unobstructed
Safety nets must extend outward from the outermost projection of the work surface as follows:
A safety net is being used under the roof of this building as an acceptable fall protection system.

10. Safety net systems (cont’d)
Vertical distance from working level to horizontal plane of net
Minimum required horizontal distance of outer edge of net from the edge of the working surface
Up to 5 feet
8 feet
5 to 10 feet
10 feet
More than 10 feet
13 feet

11. Personal fall arrest systems
Is one option of protection for workers on construction sites who are exposed to vertical drops of 6 feet or more.
Limit maximum arresting force to 1,800 pounds
Rigged so an employee can neither free fall more than 6 feet nor contact any lower level
Bring employee to a complete stop and limit maximum deceleration distance to 3½ feet
Have sufficient strength to withstand twice the potential impact energy of a worker free falling a distance of 6 feet
This worker is protected by a
properly constructed fall
arrest system.

12. Improper scaffold construction
Am I In Danger?
Working with heavy equipment and building materials on the limited space of a scaffold is difficult
Without fall protection or safe access, it becomes hazardous
Falls from such improperly constructed scaffolds can result in injuries ranging from sprains to death
This scaffold is not in compliance
with the regulations because it
mixes several different scaffold
components in the same scaffold.
The guardrails are also improper
because they are not complete.

13. How do I avoid hazards?
Construct scaffolds according to the manufacturer's instructions
Install guardrail systems along all open sides and ends of platforms
Use at least one of the following for scaffolds more than 10 feet above a lower level:
Guardrail Systems
Fall Arrest
Provide safe access to scaffold platforms
Do not use climb cross-bracing as a means of access

14. Scaffold access
Climbing the structural cross-braces of a scaffold is unsafe, and specifically forbidden
However, direct access from another scaffold, structure, or personnel hoist is permitted
If access is not possible, portable ladders, hook-on ladders, attachable ladders, stair towers, stairway-type ladders, ramps, walkways, or built-in ladders may be used

15. Types of ladders
Hook-on attachable
ladder
Stairtower
Direct access

16. Unguarded protruding rebar
Am I In Danger?
Unguarded protruding steel reinforcing bars are hazardous
Even if you just stumble onto an unguarded rebar you can impale yourself, resulting in serious internal injuries or death
Unguarded rebar

17. How do I avoid hazards?
Guard all protruding ends of steel rebar with rebar caps or wooden troughs
Bend rebar so exposed ends are no longer upright
When employees are working at any height above exposed rebar, fall protection/ prevention is the first line of defense against impalement
Rebar caps

18. Types of cap protection you can use
Rebar Caps
Rebar Caps

19. Misuse of portable ladders
Am I In Danger?
You risk falling if portable ladders are not safely positioned each time they are used
While you are on a ladder, it may move and slip from its supports
You can also lose your balance while getting on or off an unsteady ladder
Falls from ladders can cause injuries ranging from sprains to death
This ladder is being used at
the proper angle, and appears
to be stable and secure.

20. How do I avoid hazards?
Position ladders so side rails extend at least 3 feet above the landing
Secure side rails at the top to a rigid support and use a grab device when 3 foot extension is not possible
Ensure weight on the ladder will not cause it to slip off its support
Inspect prior to use
Do not apply more weight on ladder than it’s designed to support
Use only ladders that comply with manufacturers recommendations
