40. PREVENTING BACK INJURIES
The best way to prevent back injuries is to develop
habits that reduce the strain placed on the back. There
are some basic things you can do to help.
Avoid Lifting and Bending Whenever You Can!
Place objects up off the floor. If you can set
Something down on a table or other elevated
surface instead of on the floor, do it so you won't
have to reach down to pick it up again.
Raise / lower shelves. The best zone for lifting is
between your shoulders and your waist. Put heavier
objects on shelves at waist level, lighter objects on
lower or higher shelves.
41. USE PROPER LIFTING
PROCEDURES
Take a balanced stance with your feet
about a shoulder-width apart. one foot can
be behind the object and the other next to
it.
Squat down to lift the object, but keep
your heels off the floor. Get as close to the
object as you can. Keep your back
straight.
Use your palms (not just your fingers) to
get a secure grip on the load. Make sure
you'll be able to maintain a hold on the
object without switching your grip later.
42. USE PROPER LIFTING
PROCEDURES
Lift gradually (without jerking) using your leg, abdominal and buttock
muscles and keeping the load as close to you as possible. Keep your chin
tucked in so as to keep a relatively straight back and neck line.
Once you're standing, change directions by
pointing your feet in the direction you want
to go and turning your whole body. Avoid
twisting at your waist while carrying a load.
By following these lifting guidelines and by
practicing good body/back management,
you can prevent back injuries on the job and
at home.
43. FINALLY…….
Don’t forget the most common
causes of back injury
Bending
Twisting
Heavy Lifting
Stay safe, someone at home is waiting for you
45. Confined Space Entry
Definitions:
The entrant is the person who enters a confined space.
The attendant is the person who stays with the entrant
outside the confined space, and is responsible for assisting
the entrant in exiting the confined space, and calling for
emergency assistance when required.
The safety representative is the qualified person who
evaluates the hazards, prescribes required equipment
and precautions and issues the Confined Space Entry Permit.
46. CONFINED SPACE ENTRY -
HAZARDS
Both animal and plant life
require oxygen to live. One of the
primary hazards of entering
confined spaces is oxygen
deficiency.
When oxygen is present in
concentrations less than 19.5%
the atmosphere is said to be
oxygen deficient.
O2
O2
47. CONFINED SPACE ENTRY - HAZARDS
Oxygen in concentrations
greater than 23% is too
oxygen rich and can cause
combustible materials to
ignite very quickly.
48. CONFINED SPACE ENTRY - HAZARDS
Oxygen deficiency can be caused by several
processes:
Consumption: oxygen is used up by the person who is in the
confined space and turned into carbon
dioxide.
Displacement: denser materials push the oxygen out of
the occupied space.
Reaction: oxygen is reacted with other materials
to make other compounds.
49. CONFINED SPACE ENTRY
The entry of a confined space begins with a
Confined Space Entry Permit.
Confined Space Entry Permit
Location and Description of Confined Space:
Reason for Entry:
Permit Issued to (Name of Company/Organization):
The permit system requires
that a qualified safety
representative visit the
work location and evaluate
the conditions under which
entry will be made.
50. CONFINED SPACE ENTRY
Each process hazard to which
the entrant may be exposed,
adjacent operations or processes,
and scheduled activity
are reviewed. For each hazard
identified, countermeasures
are detailed on the Confined
Space Entry Permit.
51. CONFINED SPACE ENTRY
The safety representative
tests the space for
hazardous concentrations
of known harmful
substances, such as
hydrogen sulfide,
carbon monoxide, and
flammable liquid or gas.
The concentration
of oxygen is measured
at the same time.
52. CONFINED SPACE ENTRY - HAZARDS
If concentrations of
materials are found to
be at harmful levels,
the confined space
must be ventilated to
remove them before
entry.
??
??
??
Fresh Air
Fresh outside
air is blown into
the space to dilute
and remove
contaminants, and
supply oxygen.
O2
O2
O2
O2
53. CONFINED SPACE ENTRY
Means of emergency rescue
must be readily available
to the confined space
entry attendant for
emergency
extrication of
entrants.
54. CONFINED SPACE ENTRY
A means must be provided
for both safe normal entry
or exit , and emergency
disconnection. Tripods with hoist,
lifeline, and full body harness
are often used for emergency
extrication. Ladders may be
used for ordinary entry and
exit.
55. o
Danger
Do not use!
CONFINED SPACE ENTRY
Confined Space Entry Permit
Requirements
Ground Fault Interruption yes no
Lockout of Hazardous
Energy Sources yes no
Required countermeasures also
include prevention of electrical
shock hazards due to loss of
earth ground for portable tools.
GFCI’s are required for portable
electric tooling.
There may also be a need to
lockout and tag equipment both
in the confined space and on
adjacent equipment and processes.
56. CONFINED SPACE ENTRY
Entrants must leave the
confined space when the
monitor alarm is activated.
It is the attendant’s
responsibility to see that
the entrant leaves the
space during an alarm.
CO
CO2
O2
Entrants must constantly monitor
the confined space for toxic gases,
oxygen, and combustible gases.
Entrants will be issued a personal
monitor to wear
for this
purpose.
57. CONFINED SPACE ENTRY
The attendant should
attempt to remove the
entrant from the confined
space using tripods, hoist, and
lifelines.
Attendants are NOT
TO ENTER CONFINED
SPACES.
Only properly equipped
and trained emergency rescue
personnel may enter confined
spaces to make rescues.
58. CONFINED SPACE ENTRY - SUMMARY
Confined space entry hazards can include:
- the presence of toxic substances
- insufficient oxygen, or too much oxygen
- presence of combustible gases and liquids
- process or equipment related hazards.
- conditions changing from nonhazardous
to hazardous.
