This document provides an overview of health and safety topics related to manual handling at work. It covers legal issues under the Health and Safety at Work Act of 1974, common types of injuries from manual handling like back strains and sprains, causes of injuries from factors like posture and twisting, and guidelines for safer manual handling including using proper techniques, team lifting, and aids. The goal is to introduce the main objectives around identifying hazards and controlling risks from manual tasks.
Introduces the course on Health and Safety at Work led by Gary Raven, highlighting its aims and objectives.
Discusses key legal terms associated with common law, including 'duty of care', and its implications.
Covers the Health and Safety at Work Act 1974, emphasizing employee duties and responsibilities.
Focuses on types of manual handling injuries, accident statistics, and risks associated with lifting.Analyzes the physics of lifting techniques, detailing the pressure exerted on the lower back.
Describes causes of injuries and methods for reducing risks in manual handling and team lifting.
Recaps the course objectives and assessments related to manual handling and health and safety practices.
Types of Injury
Thesecan become damaged due to being over-stretched or torn
by unnatural or sudden movement or inflamed due to repetitive
action
is a stretch and/or tear of a
ligament (a band of fibrous tissue
that connects two or more bones at a
joint). One or more ligaments can be
injured at the same time.The severity
of the injury will depend on the
extent of injury (whether a tear is
partial or complete) and the number
of ligaments involved.

Types of Injury
isan injury to either a
muscle or a tendon (fibrous
cords of tissue that connect
muscle to bone). Depending
on the severity of the injury, a
strain may be a simple
overstretch of the muscle or
tendon, or it can result from a
partial or complete tear.
Types of Injury
Areoften the result of another injury e.g. as a result of harm to a
disc or limb
Are often caused by inappropriate handling of sharp objects
Are caused by compression of internal body parts due to poor
posture

Anytime you bendor lean over to pick something up, you put
tremendous pressure on your lower back.
To demonstrate this, think of your
back as a lever. With the fulcrum
in the center of the lever, how
many pounds would it take to lift
a ten pound object? With the fulcrum in the center, it
takes 10 pounds to lift the 10-
pound object. However, if you
shift the fulcrum to one side, it will
change... If you think about it,
when you bend over to pick
something up, your waist acts as
the fulcrum point in a lever
system; and it is certainly not
centered.
36.
With the fulcrumshifted away from the object, it takes more
force to lift the object. In fact, the human back operates on a
10:1 ratio.
Bending over to lift a
ten pound object
actually puts 100
pounds of pressure on
your lower back.
37.
Lifting from theFloor
When you add in the 105
pounds of the average
human upper torso, you
see that lifting a ten pound
object actually puts 1,150
pounds of pressure on the
lower back.
If you were 25 pounds
overweight, it would add
an additional 250 pounds
of pressure on your back
every time you bend over.

• Posture - Sitting for long
periods in a position that is not
ergonomically sound will
increase the risk of muscular-
skeletal injuries
• Duration
• Pre existing conditions
• Ref : HS(G) 60 Guidance note
Good HandlingTechnique
The feetshould be apart with one leg slightly forward to maintain balance
(alongside the load, if it is on the ground)
Get a good hold
Start in a good posture
70.
Good HandlingTechnique
. Avoidtwisting the back or leaning sideways especially while the back is bent
Keep the head up when handling
Move smoothly
Don’t lift or handle more than can be easily managed
Put down, then adjust

Team Lifting
• Therecommended lifting capability of a
• Of 2 person team is 60% the sum of the individual
capacity
• 3 person team is 50% the sum of the individuals
capacity
• NOTE: Teams of more than 4 not
very successful!
