Emergency procedure

“ Manual Handling ” means any activity requiring the use of force exerted by a person to lift, lower, push, pull, carry or otherwise move, hold or restrain a person, animal or thing .

Manual Handling also includes any activity

involving repetitive and/or forceful movements (e.g. keying data into a computer; using a screwdriver)

and any activity where the person must maintain constrained or awkward postures

Working at arms length from the body is hazardous Using hand tools in awkward posture is hazardous

Bending into storages on the ground is bad for your back Exerting high force above shoulder height increases the risk of injury

Bending and lifting is hazardous for your back Pushing objects in awkward posture is bad for your back

Examples Of Manual Handling Activities Include:

Manual Handling injuries are

the single biggest group of injuries .

More workers receive injuries from Manual Handling than any other category of injury.

Manual Handling injuries affect workers of any age.

Young men, 18-25yrs, most common injury is from lifting or being struck by moving objects.

Manual Handling Injury Stats. Source: Worker’s Compensation Statistical Reports: 1998/99 – 2001/02, 1999/00 – 2002/03 In the period March 2006 to April 2007 there were a total of 105 workplace injuries at Ausdrill out of theses 75 were classed as Manual Handling or 71.5% State Based Stats 93.8 days 4.7 Females 81.0 days 5.6 Males Duration (average no. of days lost) Frequency (no. of lost time injuries per million hours worked)

Weight Limits

There is no specified weight limit for an individual lift.

It is up to the individual to assess the weight and decide whether it is safe to lift

Manual Handling Injuries May Result From:

gradual wear and tear caused by frequent or prolonged periods of Manual Handling activity (e.g. a storeperson continually handling stock between deliveries);

sudden damage caused by intense or strenuous Manual Handling or awkward lifts (e.g. A labourer lifting a compactor or a mechanic/engineer lifting heavy metal to be machined

direct trauma caused by unexpected events (e.g. a storeperson walking on uneven ground carrying a large heavy carton, trips and falls, poor housekeeping).

Experience has shown most Manual Handling injuries are associated with day to day tasks.

Very often there is no ‘accident’ (sudden or unexpected event) associated with the injury.

The person may not feel pain until several hours after the injury occurs.

Injuries from Manual Handling

Conditions known as:

RSI repetitive strain disorder

OOS occupational overuse syndrome

Soft tissue damage injuries, strains & sprains,

MSD muscular-skeletal-disorder. Damage to soft or bony material.

Manual Handling Injuries Occur In Many Areas Of The Body

Common Injury Site Is The Spine Picture showing spine and different areas The most common site of injury in the spine is the lower back between L4/5 and L5/S1.

Risk Factors In Manual Handling

A number of factors can increase the risk of injury, including:

size, shape and weight of objects (if carried or held) and forces required (if pushed, pulled or restrained);

sudden unexpected or jarring movement;

awkward movements, such as twisting, bending, over-reaching, especially if combined with load handling;

static postures, like holding the body or part of the body in a fixed position for a long time; and

personal factors, such as age, physical dimensions and any disabilities the person may have.

This activity is a Manual Handling hazard. The weight alone is sufficient to cause injury. Disc compression due to excess weight

Risk Factors In Manual Handling

These risk factors are influenced by:

how long and how often the tasks are performed (eg. repetitive movement);

the way work is organised , such as one employee performing all manual handling tasks instead of tasks being shared by several employees;

design and layout of work environment; and

the degree of familiarity with the task and associated training.

This activity may be a Manual Handling hazard. Additional information is required regarding task duration, how far the load is carried etc.

Repetitive or Sustained Force

Repetitive means done more than twice in a minute for more than 30 minutes in a given shift.

Sustained force means done for more than 30 sec’s at a time.

So any Manual Handling that fits into these descriptions is considered hazardous.

Repetitive or Sustained Awkward Posture Repetitive or Sustained Movement

Bending or Twisting the back forwards or sideways more than 20 degrees

Bending the back more than 5 degrees backwards

Sideways bending compressing discs

Bending or Twisting the neck forwards or sideways more than 20 degrees

Bending neck backwards greater than 5 degrees

Twisting of the spine may cause soft tissue damage

Working with one or both hands above head height.

Reaching forwards or sideways more than 30cm from the body

Uneven disc load due to leaning

Squatting, kneeling, crawling, lying, semi-lying or jumping.

Standing on one leg etc

Excessive bending of the wrist

Manual Handling injuries occur in many areas of the body, not just the spine.

E.g. wrist strain & carpal tunnel syndrome, knee injury etc

Mythbuster

Back belts are effective in reducing back injuries .

Back belts, also known as lumbar or weight lifters' belts, or back support devices, are designed to be worn by people performing some form of manual handling, particularly lifting weights.

Back belts don't reduce the forces on the spine

Back belts don't reduce the strain on muscles, tendons and ligaments

Back belts do nothing to reduce fatigue or to increase the ability to lift

Back belts can increase blood pressure and breathing rate

Back belts don't reduce the chance of injury or reduce back pain

BUSTED

Mythbuster

Job rotation does eliminate Manual Handling hazards

1. Ineffective job rotation may increase worker exposure to the risk of developing a musculoskeletal disorder (MSD).

2. Job rotation doesn't eliminate the risk of MSD from Manual Handling.

PREVENTING MANUAL HANDLING INJURIES

Your employer has a legal responsibility to provide a safe and healthy workplace for all employees.

The national standard for Manual Handling requires that all tasks in your workplace which involve Manual Handling are identified and that the risk or likelihood of injury is assessed.

Where there is a risk of injury, suitable "control measures" must be introduced..

Control Measures Need To Be

Suitable and Practical

redesigning the task or load that needs to be moved;

providing mechanical handling devices such as hoists or trolleys;

safe work procedures such as team lifting; or

specific training for particular handling tasks.

Individuals At Work

Each employee has a ‘duty of care’ which states they have to not put themselves or others in the workplace at risk.

Individuals should take note of hazardous manual handling tasks and take steps to reduce the risk to themselves/workmates .

As An Employee,

if you are aware of anything in your workplace which could be a Manual Handling risk, you should discuss it with your manager or supervisor and try to find the best way of eliminating or reducing it.
