Safe Practices
Drug/Alcohol/Prohibited Articles Policy



Never bring drugs or
alcohol to work, or
come to work while
under the influence
Do not bring weapons,
hazardous or other
prohibited items to work
Refer to your
company’s written
policy for specifics
Proper Work Clothing



Long-sleeved cotton shirts
(considered best practice
but not required unless
doing “Hot” work)
Full-length cotton pants
without cuffs (considered
best practice but not
required unless doing “Hot”
work)
Leather work boots or shows
that are slip-resistant
Personal Protective Equipment (PPE)

Ladder Safety







Inspect ladder frequently
Get help standing ladder
Use the “4 to 1” Rule
Leave at least 36” of ladder
above roof
1 person should stabilize the
ladder as another climbs – 1 at
a time!
Maintain 3 points of contact
while climbing ladder
1st person to the top must tie
off ladder
Ladder Use Don’ts
Never stand on the top
or next to the top rung
of a ladder
Do not use ladders that
have broken or missing
parts.
Do not carry materials
or tools in one or both
hands as you climb a
ladder; safely hoist
items to the roof
instead
Scaffold Systems

If a scaffold is used and
there is a chance you
may fall more than 10
feet, you must also use
guardrails and/or a
Personal Fall Arrest
System (PFAS).
Scaffolds may only be
erected b trained
personnel
Fall Protection



Be aware of the crew’s
fall protection plan
Fall protection must be
utilized if there is a fall
hazard of 6 feet or
more
OSHA allows
alternative procedures
for “residential” fall
protection
Slide Guards




Slide guards are required if the roof
slope is over 4 in 12
“Conventional” fall protection must
be used anytime the slope is more
than 8 in 12, or if the eave height
exceeds 25 feet.
When working on tile or metal roofs
up to and including 8 in 12, the
safety monitoring system may be
used, but slide guards alone may
not.
All slide guards must be
constructed of 2”x6” (nominal)
stock, mounted on roof jacks or
similar supports, using nails long
enough to withstand a roofer sliding
into the guards.

Slide Guards



No more than 3 rows of roofing
material installed across the
lower eave may be applied
before installing the slide
guards.
The face of each slide guard
must be perpendicular – about
90 degrees – to the surface of
the roof.
To use slide guards properly,
you must install continuous
slide guards along the entire
eave on the surface that any
roofer will work in.

Safety Monitor Systems




The safety monitor must be able to observe and communicate
verbally with all of the roofers he or she is responsible for
monitoring, when they are not able to use other forms of fall
protection.
The safety monitor’s responsibility is to warn any worker who
appears to be in danger, and to maintain any and all fall
protection systems that are in use.
Only qualified persons who have completed the Safety Monitor
Training will be utilized as a Safety Monitor.
If you have been trained as a Safety Monitor, you have the
authority to stop any ongoing work of those you are monitoring.
If you feel you cannot effectively provide protection for the
workers, stop the work, have the worker(s) move away from the
roof edge and consult your foreman.
Slip Hazards


Always wear
appropriate footwear to
reduce the potential for
slipping.
Inspect all roof surfaces
for slipping hazards.
Either eliminate any
hazards or take
effective measures to
avoid them.
Good Housekeeping




Keep the worksite as neat as possible. Be careful that debris
does not fall from the roof, and designate a specific area where
tear-off and other waste will be dumped.
Place a warning line around dumpsters and areas where debris
will be lowered from the roof, to warn workers, pedestrians and
children of danger.
Always keep the area below the eaves and rakes clear of
materials around other objects that could pose impalement or
other hazards. Pick up trash around the jobsite every night.
Any time there is the possibility of objects falling from above,
especially when you are below the rake edge of a roof, always
wear a hardhat. Your foreman may require you to wear a
hardhat at other times, or at all times.
Bad Weather


When high winds, rain,
lightning, snow or sleet
create hazardous
conditions, stop all roofing
operations until the
hazardous conditions no
longer exist.
Extreme caution and fall
protection must be used if
you need to clear sleet or
snow from a sloped roof.
Roof Holes and Openings





Inspect the roof deck for weaknesses,
and repair any damaged portions as
soon as possible.
Securely cover and mark skylights and
holes in the roof that are two inches or
more in their least dimension.
Holes must be covered with a material
that will be capable of supporting,
without failure, at least twice the
weight of employees, equipment, and
materials that may be imposed on the
cover at any given time.
Secure hole covers to prevent
accidental displacement by the wind,
equipment or employees.
Hole covers must be color coded or
marked with the word “hole” or “cover”
to provide warning of the hazard.

Company Vehicles and Equipment


Seatbelts must be worn
at all times by anyone
who is in a company
vehicle.
Drivers must have a
valid driver’s license
that is appropriate for
the class of vehicle you
will operate.
Company Vehicles and Equipment



The driver must inspect each vehicle and any attached
equipment prior to each use. Pay close attention to vital items
such as tires and trailer hitches. Your company may require you
to fill out paperwork every time you drive a vehicle.
Also, note any potential hazards or obstacles around the
vehicle. If you will be backing the vehicle up, especially with a
trailer, look around and plan where you will back up BEFORE
you get behind the wheel.
Operating company equipment, such as heavy equipment, may
require certain training and/or certification. Consult your
foreman before operating company trucks and equipment.
Hazard Communications




Never remove labels from these
products or change the contents of
a labeled container.
The company maintains an
inventory list of all chemicals used,
with corresponding Material Safety
Data Sheets (MSDS) of the
products that contain hazardous
materials.
Make sure you understand the risk
posed by every chemical you use
by reviewing the container’s label or
MSDS.
If a chemical you use for work is not
on the company’s list, advise your
foreman.
Hazard Communication



If you are not sure of the risks
of a particular chemical that you
encounter at work, please ask.
Some roofing systems include
hazardous chemicals that may
require special PPE or emit
fumes that can be ignited at low
temperatures. Consult your
foreman for the designated
smoking area or if you have
questions concerning the
chemicals you are working with.
DO NOT SMOKE around
flammable materials or
chemicals. Chemicals and
smoking do not mix!
Extension Cords and Power Tools



Extension cords and power
tools must always be protected
by Ground Fault Circuit
Interrupters or “GFCI”.
Electrocution results in internal
and external injury, often
resulting death. Internal or
external burns may result from
contact with electricity.
12% of young workers die from
electrocution on jobsites. About
5 workers are electrocuted
every week in the U.S.
Electrocution




After receiving a “jolt” of electricity all or part of the body may be
temporarily paralyzed, resulting in loss of grip or stability. You
may also involuntarily move as a result of receiving an electrical
shock, resulting in a fall.
Overhead power lines are especially hazardous for roofers.
Fatal electrocution is the main risk, but burns and falls from
elevation are also hazards.
Electricity may “arc” or jump right out of the power line if even if
you don’t touch it. Keep your body and all others items at least
10 feet from overhead lines.
Get the owner or operator of the lines to de-energize and
ground them if you will need to work near them. Other
protective measures include guarding or insulating the lines.
Electrocution



Use non-conductive wood
or fiberglass ladders when
working near power lines.
Tools and equipment such
as ladders, cranes,
scaffolds, backhoes,
scissor lifts and raised
dump truck beds can
increases the risk caused
by overhead lines.
Electrical hazards may
result from too many
devices plugged into a
circuit, causing heated
wires and possibly a fire.
Electrocution



Damaged tools may overheat,
or wire insulation may melt,
which may cause a fire –
sometimes even inside a wall or
elsewhere down the electrical
line.
Frequently inspect cords and
electric tools for worn or broken
parts. Remove from service any
extension cords or power tools
that require repair, and report
them to your supervisor.
Strain relief boots must remain
intact where cords meet power
tools.
Electrocution



Wet clothing, high humidity,
and perspiration increase
your chances of being
electrocuted.
Don’t use electrical tools in
wet or damp conditions.
Store tools in a dry place.
Nail guns may be very
dangerous. Construction
workers have been killed by
nails fired through plywood
by power actuated tools.
Electrocution



Never carry a tool by the cord, or
yank the cord to disconnect it.
If voltage polarity or other aspects of
your power source are incorrect,
OSHA may site you with a safety
violation even if you did not install the
electrical drop that you are using. A
plug-in receptacle analyzer is an
inexpensive tool that checks polarity
and grounding. Use it to diagnose
wiring problems such as reversed
polarity, open neutrals, or missing
grounds.
Do not attempt to correct electrical
problems yourself – notify your
foreman of the problem.
DO NOT CARRY TOOLS
OVER YOUR SHOULDER
Fire Hazards



Inspect fire extinguishers
annually and prior to using
them on the roof
Immediately recharge
discharged extinguishers,
or replace them with a
charged extinguisher.
If your application involves
torch applied roofing, refer
to CERTA training.
Material Handling




Supplies and materials must never
be stored within 6 feet of the rake
edge, or within 3 feet if tile roof
systems are being installed.
If your supplier will load material to
the roof, make sure he complied
with this OSHA rule; otherwise,
YOU may be the one receiving the
citation.
It’s important to remember when
lifting heavy objects to ask a coworker to help you.
When lifting, always keep your
back straight, bend at the knees,
keep the object close to you, and
lift with your legs – DO NOT LIFT
WITH YOUR BACK!
