Occupational Safety and Health
• encompasses the social, mental and physical well-being of workers, that is the “whole person”

The World of Work then …
"a foul and poisonous dust [that] flies out from these materials, enters the mouth, then the throat and lungs, makes the workmen cough incessantly, and by degrees brings on asthmatic troubles."
"in whom he found heaps of sand that in running the knife through the pulmonary vesicles he thought he was cutting through some sandy body."

Lesson 2.
Know the conditions of work and
workplace
![Page 8: Promoting Safety and Health in the Workplace Ppt 89](https://reader033.vdocuments.net/reader033/viewer/2022061105/54408b18afaf9f80338b4953/html5/thumbnails/8.jpg)
Occupational and Work-Related Diseases and
Injuries
• History of exposure to hazardous workplace factors becomes indispensable in determining whether an illness is because of workplace factors or not.

Lesson 3.
Mere exposure to hazard does not
cause harm to safety or health
![Page 15: Promoting Safety and Health in the Workplace Ppt 89](https://reader033.vdocuments.net/reader033/viewer/2022061105/54408b18afaf9f80338b4953/html5/thumbnails/15.jpg)
Hazards in the workplace can cause harm if there is undue exposure such as through elevated workplace concentration without proper control measures.
Important to characterize exposure
![Page 16: Promoting Safety and Health in the Workplace Ppt 89](https://reader033.vdocuments.net/reader033/viewer/2022061105/54408b18afaf9f80338b4953/html5/thumbnails/16.jpg)
Work-Related Musculoskeletal Disorders (WMSDs)
development requires weeks, months or years of exposure to ergonomic risk factors
•Repetitive exertions•Posture stresses (including static posture)•Forceful exertions•Contact stresses•Job design•Work organization•Workstation dimension

Diseases of Workers
• Many diseases of occupational cause are multifactorial,with non-occupational factors playing a role.
• Personal characteristics, other environmental and socio-cultural factors usually play a role as risk factors for these diseases.
![Page 19: Promoting Safety and Health in the Workplace Ppt 89](https://reader033.vdocuments.net/reader033/viewer/2022061105/54408b18afaf9f80338b4953/html5/thumbnails/19.jpg)
Total Health Promotion
• Smoking cessation
• Physical activity
• Nutrition
• Weight reduction
• HIV/AIDS
• Drug Abuse Prevention
• TB Prevention and Control

Lesson 5.
Prevention is better than treatment
![Page 21: Promoting Safety and Health in the Workplace Ppt 89](https://reader033.vdocuments.net/reader033/viewer/2022061105/54408b18afaf9f80338b4953/html5/thumbnails/21.jpg)
HARMFUL EXPOSURES
EARLY IN WORKING LIFE
MODIFY NORMAL COURSE OF
PHYSIOLOGICAL CHANGES
DUE TO AGEING ALONE
![Page 22: Promoting Safety and Health in the Workplace Ppt 89](https://reader033.vdocuments.net/reader033/viewer/2022061105/54408b18afaf9f80338b4953/html5/thumbnails/22.jpg)
Hearing loss comes with ageing
But hearing loss
can occur much earlier
due to occupational exposure
![Page 23: Promoting Safety and Health in the Workplace Ppt 89](https://reader033.vdocuments.net/reader033/viewer/2022061105/54408b18afaf9f80338b4953/html5/thumbnails/23.jpg)
Noise-Induced Hearing Loss
![Page 24: Promoting Safety and Health in the Workplace Ppt 89](https://reader033.vdocuments.net/reader033/viewer/2022061105/54408b18afaf9f80338b4953/html5/thumbnails/24.jpg)
Loss of muscle strength comes with ageing
• But muscle strength can be diminished even in young persons
![Page 25: Promoting Safety and Health in the Workplace Ppt 89](https://reader033.vdocuments.net/reader033/viewer/2022061105/54408b18afaf9f80338b4953/html5/thumbnails/25.jpg)
Occupational Safety and Health is Prevention
• Many occupational conditions are IRREVERSIBLE
• Occupational conditions are PREVENTABLE
![Page 26: Promoting Safety and Health in the Workplace Ppt 89](https://reader033.vdocuments.net/reader033/viewer/2022061105/54408b18afaf9f80338b4953/html5/thumbnails/26.jpg)
ENSURING WORKER WELL-BEING
• “The choice of a starting age for attention should be selected as “young” enough that intervention efforts can be expected to make a difference during the working life.”

Occupational Safety and Health in Call Centers
(Secondary Data)
• Musculoskeletal disorders– Linked to poorly designed workstations (Hoekstra et.
al. 1995).– Associated with longer shift duration (Ferreira M and
Saldiva PH, 2002)– Long uninterrupted hours of work with the computer– Invariable and sedentary work (Norman K et. al.
2001)– Low job satisfaction (Most IG, 1999)
![Page 29: Promoting Safety and Health in the Workplace Ppt 89](https://reader033.vdocuments.net/reader033/viewer/2022061105/54408b18afaf9f80338b4953/html5/thumbnails/29.jpg)
Occupational Safety and Health in Call Centers
(Secondary Data)
• Voice disorders– Intensive verbal interaction with clients one of
the contributing factors (Jones K et. al., 2002)
• Eyestrain– Poor lighting conditions and intensive
computer use (Putnam C et. al., 2000)
![Page 30: Promoting Safety and Health in the Workplace Ppt 89](https://reader033.vdocuments.net/reader033/viewer/2022061105/54408b18afaf9f80338b4953/html5/thumbnails/30.jpg)
Occupational Safety and Health in Call Centers
(Secondary Data)
• Problems due to psychosocial and work organization stressors (Putnam C et. al., 2000)– Increased reporting of health disorders– Negative work attitude (boredom, job
dissatisfaction, anger, etc.)
![Page 31: Promoting Safety and Health in the Workplace Ppt 89](https://reader033.vdocuments.net/reader033/viewer/2022061105/54408b18afaf9f80338b4953/html5/thumbnails/31.jpg)
Occupational Safety and Health in Call Centers
(Secondary Data)
• Concern over potential hearing problems (Patel J and Broughton K, 2002)– Exposure to high intensity sound coming from the
headsets– high sound levels in the room from the simultaneous
talking of the employees
![Page 32: Promoting Safety and Health in the Workplace Ppt 89](https://reader033.vdocuments.net/reader033/viewer/2022061105/54408b18afaf9f80338b4953/html5/thumbnails/32.jpg)

Methods
• Case study of 5 call centers
• Purposively selected employees from one (1) company– Questionnaire to collect data about personal
circumstances, occupational profile, medical and psychosocial conditions
– Company profile• Data will be collected regarding the organization in
terms of size, tasks, type of clients, work organization, working hours, etc. Information on incentive system will also be gathered.

Implications of the Study
• Knowledge gained to be used to improve working conditions– In existing and prospective new call centers– Address the OSH problems at an early stage
• Policy/Program Implications– needs of women, mothers, young workers– policies concerning work shifts, esp. prolonged
night work– adequate, on-site medical and health
promotion facilities
![Page 48: Promoting Safety and Health in the Workplace Ppt 89](https://reader033.vdocuments.net/reader033/viewer/2022061105/54408b18afaf9f80338b4953/html5/thumbnails/48.jpg)
Implications of the Study
• Recognition of complex nature of safety and health issues in call centers– Interaction of psychosocial factors with other work
factors – Unique work organization because of electronic
monitoring– High performance standards– Issues on job security
• Compensation implications– Recognition of problems of workers in call centers
• Associated with air quality, ambient noise, noise from headset, human-computer interaction, shift work, etc.

Approach in EnsuringWell-Being of Workers
• Looking at regulatory requirements
• Relevant laws, standards, issuances and guidelines– Enforcement– Implementation– Inspection– Evaluation
• Looking at developmental strategies
• Information• Education• Training• Campaigns• Good practices• Successful cases• Competitions• Demonstrations• Interventions
