12
INTRODUCTION

• Physical tasks in factories and services have
  often been divided into light and heavy , a
  division that often corresponds formally or
  informally to GENDER.
• In this paper,researchers observed the work of
  cleaners on wards and in offices in an acute-care
  hospital (Quebec), using several indicators of
  workload to identify and characterize typical
  work situations.
• In order to sum up the purpose, this paper
  describes an analysis of the work activity of a
  group of cleaners to identify problematic aspects
  of cleaning and to examine work organization by
  gender.

13
METHODS

• The chosen method integrates observation of work
  activity in the workplace and collection of
  perceptions of work in order to create a portrait
  of the working conditions and to improve work
  organization and design
• Three stages can be mentioned in this manner.

14

• 1.Stage General Description
• This stage allowed identification of determinants
  of
• Perception of light and heavy work
• Typical operations
• Problem operations
• Difficulties in cleaning work

15

• 2.Stage Preliminary Observations
• The work of most of the cleaners assigned to
  daywork in
• offices and on wards for a total of 35.75 hours
  on 5
• different weekdays is observed at this stage.
• With the help of workers,critical work situations
  which
• were characteristic of the activity were
  identified.

16

• 3.Stage Detailed Observations
• Characteristics situations identified in the
  first two stages were observed in detail on 8
  different days.
• 4 workers were observed,chosen because they were
  of average age and seniority,did the major jobs
  in the hospital and accepted observations and
  videotaping
• The operations chosen to be analyzed in detail
  were the most common for LW(dusting,bathroom
  cleaning) and HW(mopping,buffing).

17

• Study Subjects
• 22 men assigned to heavy work
• 14 women assigned to light work
• 1(work-injured) man assigned to light work
• Necessary Software and Technical
• Devices
• Psion Organizer II Model Xp
• Systems GES
• Cameras-Video cameras
• Dynamometer
• Many geometrical devices

18
Results and Observations

• Most of the time of HW is occupied in
  cleaning floors,while LW spend most of their time
  dusting and cleaning bathroom fixtures.It is
  noted that both jobs involve awkward postures in
  crowded spaces to displace furniture,objects,etc..
  .

19
Discussion

• The present study uses a number of indicators
  to make
• visible various aspects of HW and LW
• Trunk posture
• Weight and number of objects displaced
• Number of obstacles
• Contrast of official inventory with objects
  cleaned
• Perception of co-workers and patients
• Although information on these points was
  gathered
• systematically,the list of indicators of
  workload is not exhaustive and could be usefully
  expanded with better equipment or more extensive
  research

20
Conclusion

• They did not discover any compelling reason to
  divide cleaning into light and heavy
  work,either based on the routine physical demands
  of both cleaning jobs or on efficiency.
• However supervisors may allow a male worker who
  does occasional dangerous or difficult jobs.

CLEANING UP

• Are you cheating your cleaning program?
• Staffing strategies can make your operations
• run more smoothly.
• JOHN
  WALKER

22
Introduction

• Most operations are organized very loosely
  when it comes to cleaning.An important part of an
  effective system is having the right number of
  people doing the job.Some problems are
• Too few cleaning workers causes quality to suffer
• Too many cleaning workers can result in costs
  rising unnecessarily
• Confusion and security may develop

23
Understanding the Cleaning

• To determine how many cleaning workers are
  needed,you need to know how much area is being
  cleaned
• Though that step sounds simple,there are a
  surprsing number of instutions with no idea how
  much cleanable space they actually have
• In most settings,the amount of cleanable square
  feet is about 55 of the total square footage
• Having more space than you estimated could result
  in not enough cleaning workers to do the job
  properly.Having less space than you thought might
  mean you are overstaffed and paying too much for
  cleaning

24
Cleaning Systems

• There are two basic types of cleaning
• Zone Cleaning each worker is assigned a certain
  zone or area and is responsible for performing
  all of the cleaning functions in the entire area.
• Team Cleaning Workers are trained to perform
  specific cleaning tasks. Consists of four areas
• Light-duty
• Vacuum
• Restroom
• Utility

25

• Team cleaning provides greater efficiency.Most
  organizations using this system see a
  10-to-20percent budget benefit
• The purpose of using team cleaning is to able do
  more with less labor,less waste,less complaints
  and less money , obtaining a higher-quality
  appearence level with less effort

Market View

• Many instutions use their facilities
  cleanliness as a marketing tool and source of
  pride.
• Also if you can project and target how
  cleaning is going to complement other marketing
  strategies ,you can minimize waste and maximize
  effectiveness.

Ergonomic Assessment of Cleaning Work

• By Christine Aickin

29
Introduction

• high frequency of back, shoulder, neck, arm and
  hand injuries.
• Most injury/disease is found in the 40-44 group.
• heavy manual work, static muscle load, repetitive
  muscle work, lifting and carrying of heavy items
  and bent and twisted positions and poor
  ergonomics bent and twisted positions and poor
  ergonomics
• psychological stress factors
• sprains and strains, limb injuries are the most
  observed injury types

30
Subject and Method
WORK TASKS

• electrostatic mopping
• damp and wet mopping
• vacuuming with a back pack vacuum cleaner
• vacuuming with a canister vacuum cleaner
• spray burnishing with a rotary suction polisher
• floor scrubbing floor stripping floor
  sealing
• cleaning internal areas
• cleaning toilet and showers
• cleaning windows and glass and
• cleaning out doors.

31
Subject and Method
WORK ORGANIZATION

• Work is organised in shifts
• indoor cleaners usually work a split shift and
  outdoor cleaners usually work a continuous shift
• Cleaners report to a head cleaner/leading hand.
  The head cleaner/leading hand reports to the area
  manager
• Cleaners can work alone or in a team
• During holidays an overall clean is performed

32
Subject and Method
CONSULTATIVE APPROACH TO THE ASSESSMENT

• observational task analysis of outdoor and indoor
  team cleaning
• measurement of weight of commonly handled
  equipment
• force measurements of common pushing and pulling
  tasks
• two dimensional static strength prediction of
  lifting a bucket, lifting A stool and lifting the
  Lift Assisted
• Working Posture Analysing System (OWAS)
  evaluation of trunk and arm postures in
  vacuuming, mopping and buffing/polishing

• OWAS is a sampling system which involves visual
  observation and analysis of posture at set time
  intervals to develop summary description of
  posture at work Vacuuming
• Mopping
• -- Back Percentage of time in posture
• -- ArmsPercentage of time in posture
• Buffing/polishing
• -- Back Percentage of time in posture
• Vacuuming
• -- Back Percentage of time in posture

39
Discussion

• Cleaners sustain a high frequency of back,
  shoulder, neck, arm and hand injuries
• The risks identified include postures required by
  tasks, duration and frequency of tasks, weights
  handled, equipment design and work organisation
  issue
• Postural risks include flexed and rotated working
  postures the requirement to lift, lower, carry,
  push and pull nd the duration of certain tasks of
  an hour or more
• The weight of equipment handled on a regular
  basis ranges from 2 - 42 kilograms. Weight is an
  important factor to be considered

40
Recommendations

• Equipment design and equipment selection
• Job design and work organisation
• Safety level for the workforce
• Job rotation or job sharing should be practiced
• Team Work Applications
• Education and training
• Maintenance and replacement program for powered
  and non-powered equipment
• the interface between schools and cleaners
• ? In the Short term
• Condition / Position of garbage bins
• Relationship between cleaners and students and
  staff
• ? In the long term
• type and quality of floor surfaces
• number and position of ramps and steps
• route for collecting garbage in outdoor areas

METHODOLOGY
42
Project Aim

• Testing our hypothesis in the light of
• ? sufficient of scientific data
• ? sufficient of observations
• ? sufficient of measurements
• and ending in a conclusion wheter the project
  hypothesis is correct or not.
• Making suggestions for improvement in the design
  of work, workplaces and equipment

43
Hypothesis
CALORIE INTAKE IS ENOUGH TO DO CLEANING WORKS IN
IE BUILDING IN CURRENT JOB DIVISION SYSTEM
44
Method
Proof our hypothesis Intake calorie is enough to
do all cleanings Way By gathering heart
beating during work time, we will calculate
oxygen usage and then calculate calorie usage
during the work. As a result, we will be able to
compare it with calorie intake which will be
known by calorie of each food.
