- 15 percent of all accidental deaths
- More fatalities than all other causes, except
motor vehicles - OSHAs standards for walking and working surfaces
apply to all permanent places of employment,
except where only domestic, mining or
agricultural work is performed.
3General RequirementsHousekeeping
- Workplaces must be kept clean, orderly
and sanitary. - Workroom floors must be maintained as clean
and dry as possible.
4General RequirementsAisles and Passageways
- Keep clear and move obstructions that could
create a hazard. - Mark permanent aisles and passageways.
- Aisles must be sufficiently wide where mechanical
handling equipment is used.
5General RequirementsCovers and Guardrails
Provide covers/guardrails to protect workers from
the hazards of open pits, tanks, vats, ditches,
etc.
6General Requirements Skylight Floor
Opening
- Every skylight floor opening and hole shall be
guarded by a standard skylight screen or a fixed
standard railing on all exposed sides.
7General Requirements Pit
Trapdoor Floor Opening
- Every pit and trapdoor floor opening,
infrequently usedguarded by a floor opening
cover of standard strength and construction.
- While the cover is not in place, the pit or trap
opening must be constantly attended by someone or
protected on all exposed sides by removable
standard railings.
8General RequirementsFloor Loading Protection
- Load ratings must be marked on plates and
conspicuously posted. - Do not exceed the load rating limit.
9Floor Opening
An opening measuring 12 inches or more in its
least dimension in a floor, platform, pavement or
yard through which people may fall.
10Guarding Floor OpeningsDefinitions
- Standard railing
- Consists of top rail, mid rail and posts
- Height from upper surface of top rail to floor
level is 42 inches - Mid rail height is 21 inches
- Standard toeboard

clearance above the floor
11Stairway Floor Openings
Must be guarded by a standard railing on all
exposed sides (except at entrance)
12Ladderway Floor Openings
- Guard with a standard railing with toeboard on
all exposed sides (except entrance). - Guard the passage through the railing with a
swinging gate or offset it to prevent someone
from walking into the opening.
13Floor Hole
- An opening measuring less than 12 but more than
1 in its least dimension in a floor, platform,
pavement or yard through which materials, but not
persons, may fall. - Every floor hole that people can accidentally
walk into must be guarded by either - a standard railing with toeboard or
- a cover
14Wall Openings
- Opening at least 30 high and 18 wide, in a wall
or partition, through which persons may fall. - Wall openings from which there is a drop of more
than 4 feet must be guarded.
15Open-sided Floors and Platforms
- Open-sided floors or platforms 4 or more above
adjacent floor or ground level must be guarded by
a standard railing (or equivalent) on all open
sides, except where there is an entrance to a
ramp, stairway or fixed ladder. - A toeboard is required when beneath the open
sides - persons can pass,
- there is moving machinery, or
- there is equipment where falling materials could
create a hazard.
Unguarded Platform
16Open-sided Floors, Walkways, Platforms and
Runways
- Regardless of height, a standard railing and
toeboard must be used to guard - open-sided floors
- - walkways
- - platforms, or
- - runways
- Above or adjacent to dangerous equipment,
pickling or galvanizing tanks, degreasing units
and similar hazards
17Stairways
Flights of stairs with four or more risers must
have standard stair railings or handrails.
18Fixed Industrial Stairs
- Treads must be slip resistant with uniform rise
height and tread width - Must be able to carry 5 times expected load
minimum of 1,000 pounds - Minimum width of 22
Violation here several steps bent and damaged,
no railings/handrails, tools on stairs
19Portable Ladders
- Ladders used to gain access to a roof or other
area must extend at least 3 above the point of
support. - Remove defective ladders from service and tag or
mark Dangerous, Do Not Use - Never use ladders in a horizontal position as
scaffolds or work platforms. - Never use metal ladders near electrical
equipment.
Notice step ladder in use safer to use
straight ladder
20Portable Wood Ladders
- Free from sharp edges, splinters, wear and decay
- Step ladders
- - Type I 3 to 20 (heavy duty use)
- - Type II 3 to 12 (medium duty)
- - Type III 3 to 6 (light duty)
- These have a metal spreader or locking device
21Portable Wood ladders - Inspection 29
CFR 1910.25 (d)(1)(x)
- Regularly inspect ladders
- Those with defects should be withdrawn from
service for repair or destruction
and tagged or marked as "Dangerous, Do Not Use"
22 Portable Ladders
- Single/Straight ladder
- 30 feet or less
- Extension ladder
- 60 feet or less
- Painters ladder
- 12 feet or less
23Care and Use of Ladders
- Ladders must be maintained in good condition
at all times - Joints must be tight
- Metal bearings of lock, wheels, pulleys, etc.,
must be lubricated - Frayed or badly worn rope must be replaced
- Safety feet and other auxiliary equipment must be
in good condition - Ladders must be inspected frequently
24Ladders and Electricity
- Metal ladders conduct electricity be careful
where they are located when in use - Suggest metal ladders have a sign stating not
for use around electricity or electrical lines
25Ladder Angle Portable Rung and Cleat Ladders
- Use at angle where the horizontal distance from
the top support to the foot of the ladder is ¼
the working length of the ladder (length along
ladder between the foot and top support)
26Safe Use of Ladders
- Make sure the ladder is strong enough and long
- enough for the job.
- Carefully inspect the ladder before you use it.
- Place the ladder on a firm, level surface with
its - feet parallel to the wall it is resting
against. - Face the ladder when ascending or descending.
27Safe Use of Ladders
- Ensure rungs are free from grease/oil.
- Always maintain 3 points of contact when
ascending or descending. - Never splice ladders together.
Employee is maintaining three points of contact
while working
28Fixed Ladders
- Permanently attached to a structure,
building or equipment - Cages or wells are required if longer
than 20 to a maximum unbroken length of 30 - Ladder safety devices may be used on tower, water
tank and chimney ladders over 20 in unbroken
length instead of cage protection

30ScaffoldingGeneral Requirements
- Must be capable of supporting four times the
maximum intended load. - Do not alter or move while in use.
- Protect workers on scaffolds from overhead
hazards. - If higher than 10, use guardrails, midrails and
toeboards. - Use wire mesh between the toeboard and guardrail
if people work or pass underneath. - Must be equipped with access ladder or
equivalent.
31Scaffolding
- Designed by qualified person and built loaded
to design - Footing or anchorage of scaffolds must be
sound, rigid and capable of carrying the maximum
intended load without displacement - Must be capable of supporting at least 4
times the maximum intended load
32Any Problems Here?
Scaffolding unsafe no guardrails, not supported
or anchored properly, etc.
33Summary
- Slips, trips and falls constitute the majority
of general industry accidents. - OSHAs standards for walking and working
surfaces include requirements for guarding
floor/wall openings and holes, housekeeping, - industrial stairs and ladders.
- Maintaining proper clearance and aisle space
helps to prevent accidents and injuries. - Keeping working surfaces clean, dry and
uncluttered can prevent many workplace accidents.
34Remember
- A slip/trip/fall can occur in just one second,
and that one second can change your life. - Be careful, be safe and use common sense when it
comes to maintaining and using walking and
working surfaces.
