JOB BOX TALKS - TODAY’S TOPIC: FALLS AND PREVENTION
One of the most construction accidents is a fall and these can be avoided through simple effective safety measures.
Statistics indicate that over 300 construction workers are killed each year on the job as a result of a fall. Today we’ll talk about 4 subjects related to being injured in a fall on site.
• UNPROTECTED SIDES, WALL OPENINGS & FLOOR HOLES
• IMPROPER SCAFFOLD CONSTRUCTION
• UNGUARDED PROTRUDING STEEL REBARS
• MISUSE OF PORTABLE LADDERS
UNPROTECTED SIDES, WALL OPENINGS & FLOOR HOLES
Almost 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, ranging from sprains and concussions to death.
So, how do I protect myself? Depending on the nature of the hazard and potential fall height options to protect yourself include, but are not limited to:
Use of a guardrail system.
Deploying safety nets.
Use of fall arrest systems.
Important factors for guard rails:
Top rail must be between 39 and 45”.
Midrails between the top edge and the walking/working level.
Guardrail must be capable of withstanding 200 lbs of force within 2” of the
top edge, in any direction and at any point along the edge without causing
the top edge of the guardrail to deflect downward lower than 39”.
IMPROPER SCAFFOLD CONSTRUCTION
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 improperly constructed scaffolds can result in injuries ranging from sprains to death.
So how do I avoid hazards?
Construct all scaffolds only according to the manufacturer's instructions.
Install guardrail systems along all open sides and ends of platforms.
Use a guardrail system, personal fall arrest system or both for scaffolds
more than 10 feet above a lower level.
Do not climb cross-bracing as a means of access!
UNGUARDED PROTRUDING STEEL REBAR
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.
So how do I avoid these hazards?
Fit all protruding ends of steel rebar with rebar caps, wooden troughs or
bend the rebar so that the exposed ends are no longer upright.
When working above exposed rebar, fall protection/prevention is the first
line of defense against impalement.
MISUSE OF PORTABLE LADDERS
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.
So how do I avoid hazards?
Before using any ladder start with a routine inspection to assure ladder is
undamaged and fit for use.
Position ladder so the side rails extend at least 3 feet above the landing
and carefully secure the side rails at the top to a rigid support that will not
create a tripping hazard for those climbing onto or off of the ladder.
Make sure that the weight on the ladder will not cause it to slip off its
support.
Do not apply more weight on the ladder than it is designed and rated to
support.
