1 Briefing to EOH3202 Occupational Health Guide for Week 1-7 PJJ Bacelor Sains Sumber Manusia (Pembangunan) 16 February 2014 Dr. Emilia Zainal Abidin Department of Environmental and Occupational Health Faculty of Medicine and Health Sciences UPM

2 I am here to assist you Dr. Emilia Zainal Abidin BSc. Biochem (UKM), MSc. Occupational Health (UKM), PhD Environ Med (Aberdeen) Department of Environmental and Occupational Health, Faculty of Medicine and Health Sciences, Universiti Putra Malaysia Phone No.:

3 Course Synopsis This course include Discussion about the health, safety and welfare of employees and the organization and functions. Health problems caused by disease agents associated with the various types of work. Exposure to workers' compensation issues as well as stress at work. Occupational health principles, principles of prevention and control measures are also discussed.

4 Why is this course important? OPERATOR KILLED WHEN HEAVY VEHICLE PLUNGES DOWN SLOPE Borneo Post Online, 20 September 2013 FATAL PLUNGE: The wheel loader at the base of the hill following the incident. BAU: A heavy machinery operator was killed while another man was seriously injured in a freak accident at a quarry at Paku yesterday after the vehicle they were in fell off a slope and landed on its roof. Thomas and two mechanics were negotiating a hill at the site using a wheel loader after earlier inspecting a broken-down excavator. The wheel loader was said to have suddenly experienced mechanical problems of its own, resulting in Thomas bringing it to a halt before putting it into reverse. At that moment, however, the vehicle slipped and plunged about 20 metres down the hill slope and landed on its roof. Thomas died on the spot from serious head and body injuries, while one of the mechanics, a 24-year-old man, was seriously wounded.

9 Course Objectives To correlate occupational health services and the role played by the government and other institutions in the field of occupational health in Malaysia (C5, TS) To identify the source of exposure to biological, chemicals and physical agents and its hazardous effects to workers health and to control and manage the hazards (A4, LL) To understand the details of the diseases that can be found in the workplace (P4, CS)

10 Never mind the course objectives, but the most important point, how will I be assessed?

11 Course Assessment Assessment for this course is divided into: (i)Overall Continuous Assessment 30 % Assignment 1 (group work) 10 % Assignment 2 (individual) 20 % (ii)Mid-term Examination 30 % (i) + (ii)60% (ii)Final Examination 40% Overall Total 100%

12 So far any questions?

13 Assignments Topics for Group Assignment [10%] Divide yourselves into a group of 10. Select any ONE [1] of the following topic for research and write-up of report. Students are requested to search for information from reference books and from other sources available on relevant websites. 1. Identify all relevant hazards in a semi-conductor manufacturing sector/industry and methods (suggestions) to manage and control only THREE [3] major hazards which have been identified. Tip: The management and control of hazards should be described in terms of hierarchy of control (Unit 4 page 36 in module)

14 Explain hazards in terms of these: Physical: elevated objects, noise, high voltage, mechanical injury Chemical: hydrocarbon under pressure, toxic materials, solvents Biological: virus, needle stick injury Ergonomic: poor body posture, carry heavy weights, repetitive work Psychosocial: stress or violence at the workplace

15 Physical hazard

16 Chemical hazard

17 Biological hazard

18 Ergonomic hazard

19 Psychological hazard

20 Use the hierarchy of hazard control for your report

21 Individual assignments Topics for Individual Assignment 1 [4%] Please answer the given quiz and submit by the 4 th week of this semester Topics for Individual Assignment 2 [8%] (SCL) Submit your answers by the end of week 7 Topics for Individual Assignment 3 [8%] (SCL) Submit your answers by the end of week 13

22 Individual Assignment [4%] Write a short note to explain the function of each organization in the field of Occupational Health 1. Ministry of Health 2. Niosh 3. MIHA 4. DOSH 5. SOCSO 6. CIDB

26 What will happen without good occupational health governance? Bhopal tragedy, India December 1984, a highly toxic gas was leaked from a pesticide plant in city Winds spread the poison through a densely populated area Many died instantly, others as they tried to flee, more than 20,000 people died in total in the aftermath of the leak

27 Bhopal and Union Carbide

28 Recent tragedies Chernobyl nuclear disaster, Kiev, Ukraine April 26, 1986, a reactor at the Chernobyl nuclear power plant experienced a catastrophic failure Resulted in the worst nuclear power disaster in history due to a flawed reactor design and poorly trained plant personnel Amount of radiation released was at least 100 X that of the Hiroshima and Nagasaki atomic bombs combined

29 Chernobyl

30 Bright Sparklers fireworks explosion at Sungai Buloh Tragedy happened in 7 th May, 1991 Fireworks factory and fire killed 22 people and injured 103 others Bright Sparklers Sdn. Bhd violated many laws to carry out dangerous operation Commission found that legislations pertaining to siting, construction, maintenance and operations of the factory were not adhered to

31 What is Occupational Health? Definition 1: Occupational Health is the promotion and maintenance of the highest degree of physical, mental and social well-being of workers in all occupations by preventing departures from health, controlling risks and the adaptation of work to people, and people to their jobs (ILO-WHO 1950) Definition 2 - Occupational Health is the maintenance and promotion of workers’ health and working capacity, improvement of working environment and work to become conducive to safety and health and the Development of work organisation and working culture – safe, healthy and enhance productivity (ILO-WHO Committee on Occupational Health 1955)

32 Buried by mill scale at pier What would you suggest as an Occupational Health professional ( Figure 1 ). What improvements would you suggest as an Occupational Health professional? ( Figure 1 ) ( Figure 2 )

33 OH accidents: Example Buried by Mill Scale At Pier Around 8.45 am on February 24, 2012 a fatal accident occurred at Port Klang, Selangor involving a Bangladeshi employee who worked with the cleaning contractor During the accident, the victim was collecting mill scale that has spilled on the pier floor under the path of the wharf crane (capacity 20 tons), which, at the time was unloading the mill scale from vessels into the hopper on the pier ( Figure 1 ). While the grab bucket used to transport the mill scale passing through the area where the victim was working, grab bucket had opened suddenly and cause the load carried to fall and buried the victim below ( Figure 2 ). Victim died on the way to the hospital.

34 OH accidents: Example pier Hazard Identification, Risk Assessment and Risk Control [HIRARC] should be done more thoroughly Cleaning work should not be performed while the grab bucket was operating Safe work procedures Supervision over a work Investigation should be carried out on every near missed incident and dangerous occurrences The causes of these incidents, particularly those involving mechanical failure of a machine must be identified Activities such as scheduled maintenance and inspection of machineries should be performed

35 EXAMPLE OF HIRARC
