IHOH
Then do not us a Ladder!
IHOH
Ladder Access Holes
Ladder access holes must be protected.
Someone could easily fall through this hole.
IHOH
Ladder Access Holes
This is good example of a well protected ladder access hole.
The guardrails surround three sides of the hole.
IHOH
Ladders Near Electrical
Use non-conductive ladders.
Don’t carry or move extension ladders while extended.
Get help moving ladders to maintain control.
IHOH
Job Made Ladders
Job made ladders must be built to proper specifications.
They must have filler blocks between the rungs to support them in case they split.
IHOH
Ladder Jacks
Ladders must have a sufficient lean angle.
You must have fall protection!NO!
IHOH
Stupid Set Ups
Is this access? Where is the fall protection?
IHOH
Stupid Set-Ups
This is a man working on a church steeple from an extension ladder supported in an high lift aerial lift.
Need we say more!
