KEY OCCUPATIONAL HEALTH CONCEPTS
• Occupational Health is driven by two disciplines – Occupational Hygiene and Occupational Medicine. The two work in tandem through a process of health risk assessment and management.
• Occupational Hygiene is a scientific discipline devoted to the anticipation, recognition, evaluation and control of health hazards in the working environment.
• Occupational Medicine is a branch of clinical medicine concerned with employee fitness for work; medical surveillance of employees; medical emergency management; and management of return to work (rehabilitation and disability).
6
HEALTH RISK
Health Risk arises from exposure to a health hazard at a level which can cause harm either in the short or long term.
The level of risk is determined by:– the toxicity (stored energy);– the level of exposure; and – the amount of time over which exposure occurs.
Most health hazards require a certain dose (exposure level X time) before they cause a health effect.
The dose can be delivered fast in high level exposure or slowly (over many years) with low level exposure. In the former there may be acute illness whereas in the latter illness may develop over a long period of time.
This is the basis of the occupational exposure limit (OEL).
7
OCCUPATIONAL EXPOSURE LIMITS
The OEL is defined as a level at which nearly all workers can be repeatedly exposed, day after day, over a working lifetime without adverse health effects.
The work day is taken as an 8 hour day and a 40 hour work week, and a working lifetime is typically taken as 40 years.
OELs are constantly being revised downwards as new information on health risk becomes available.
If exposure is constantly above the OEL then an adverse outcome is highly likely over time; the higher the exposure the shorter the time required for the adverse affect to appear.
Since many people are exposed the number of people who will experience an adverse outcome is always large.

WHAT WE ARE DOING TO ADDRESS OUR MAIN HEALTH RISKS?
APPLICATION OF OCCUPATIONAL HEALTH STANDARDS
• Focus on preventing the adverse health consequences of exposures tooccupational health hazards
• Programmatic approach
Risk assessmentEducation and trainingControlsMonitoring and review
• Initial standards address priority risks
Noise Airborne pollutants Fatigue Emergency Medical Response Alcohol and Substance Abuse Ergonomic Factors (musculoskeletal) – in development
12
• The process for managing health risk is exactly the same as for safety using the same terminology and skills as the Operational Risk Management Process (ORMP)
– Documented in the Anglo American Occupational Health Way
– Risk and (Critical) Control Registers
– Issue based risk assessment
– Identification of gaps
– Reporting and investigationof health incidents

Example Occupational Health Standard
RESPIRATORY PROTECTION PROGRAMME STANDARD
AIMTo provide a consistent and rigorous approach to the prevention of ill-health from airborne pollutants occurring in the work environment. The Standard provides the basis for a programme to manage the risk from inhalable hazards.
STANDARD ELEMENTS● Risk assessment
Identify the sources and characteristics of the hazard, the tasks and people that are affected. Assess the level of exposure (intensity and dose) for each task. Indentify the opportunities for control and protection of any employees who may be exposed.
● Education and training of employees On the respiratory hazards to which they are exposed, the controls that are in place and how to
prevent exposure.● Controls
Application of the hierarchy of controls to management of sources of airborne particulate and gaseous emissions.
● Monitoring and Review Monitoring the effectiveness of controls and of the exposure of the employees at risk through the
occupational hygiene and medical surveillance programmes and using the information obtained to further improve the controls.

• Access to treatment has transformed the management of HIV and AIDS
• New evidence supports the vital role that treatment plays in prevention
• Anglo American was the first large business in South Africa to offer free antiretroviral therapy to all its employees – 6th August 2002
• This commitment was extended to the dependants of all employees in 2008
• AIDS treatment costs ~R900 per employee per month, but can save up to R1500 per employee per month through reduced absenteeism, reduced hospital costs, reduced staff turnover and reduced benefit payments

38*Benefits include: disability, ill-health early retirement, death benefits, dependant pensions
CONCLUSIONS OF LSHTM STUDY
The cost of AIDS in the workforce is due to:• Increased benefit* payments 44%• Absenteeism 39%• Training and recruitment 7%• Medical costs 10%
The cost of ART makes up only 5% of the cost of AIDS
The savings under ART are mainly due to reductions in benefit payments and absenteeism costs
Anglo American Thermal Coal mines have been saving 9% on the annual cost of HIV/AIDS by making ART available to their workforce since 2003 ($31.2 million reduced to $27.6 million)
These results are based on real programme experience over 10 years
The results demonstrate strongly that investment in treatment is worthwhile

HIV/AIDS CHALLENGES FOR ANGLO AMERICAN
TUBERCULOSIS
41
• TB in the mining industry has reached crisis proportions. It is fuelled by the HIV/AIDS epidemic.
• People living with HIV are about 37 times more likely to develop TB, than people without HIV.
• TB is difficult to diagnose, especially in people living with HIV.
• TB is curable, but treatment takes at least 6 months and requires meticulous adherence.
• If treatment is not taken properly, then the TB bacilli rapidly become resistant.
– Multidrug Resistant TB (MDR-TB) requires two years of treatment at more than 30 times the cost
– Extensively Drug Resistant TB (XDR-TB) is untreatable

TUBERCULOSIS IN SOUTHERN AFRICASADC DECLARATION ON TB IN THE MINING SECTOR 18TH AUGUST 2012
We the Heads of State orGovernment of;
The Republic of AngolaThe Republic of BotswanaThe Democratic Republic of Congo The Kingdom of Lesotho The Republic of MadagascarThe Republic of MalawiThe Republic of MauritiusThe Republic of MozambiqueThe Republic of SeychellesThe Republic of South AfricaThe Republic of SwazilandThe United Republic of TanzaniaThe Republic of ZambiaThe Republic of Zimbabwe
CONCERNED that the mining sector is one of the hardest hit by the TB and TB/HIV crisis imposing many costs on the business and eroding the positive contribution made by the mining sector to the economic development agenda of the region
RECOGNISING that the mining sector contributes to TB prevalence in the Region and that mineworkers are disproportionately affected by TB
FURTHER RECOGNISING that the TB and TB/HIV epidemics in the mining sector are driven by many factors including high prevalence of Silicosis resulting from long term exposure to silica dust in the mines and that in addition, high prevalence of HIV in the mines combined with generally poor living conditions of mineworkers further increases the risk of contracting and developing active TB
AWARE of the challenges being experiences by mineworkers and ex-mineworkers (including migrant mineworkers and contract or casual workers) their families and communities.
COMMIT to moving towards a vision of zero new infections, zero stigma and discrimination , and zero deaths resulting from TB, HIV, Silicosis and other occupational respiratory diseases
44
• SADC Heads of State have highlighted a critical development challenge:
– a regional crisis where a key economic sector (mining) is accelerating the spread of TB throughout the continent to the extent that Africa is the only region in the world that is not on track to reach the Millennium Development Goal (MDG) for Tuberculosis
• South Africa’s half-a-million mineworkers have the highest TB incidence in the world: 3,000 per 100,000 compared with a global incidence rate of 128 per 100,000
• Contractors are a significant and neglected part of the problem
TUBERCULOSIS IN SOUTHERN AFRICA
AFTER KNOWING FOR MORE THAN A CENTURY THAT
THE SOUTH AFRICAN MINING INDUSTRY IS RICH
WITH TB, WE FINALLY HAVE THE POLITICAL WILL IN
THE REGION TO CREATE AN EMERGENCY
RESPONSE TO ARREST ITS SPREAD.
FOR THE HEALTH OF THE REGION—AND TO
PROTECT A WORLD AT GREATER RISK FROM TB—
WE MUST SEIZE THE OPPORTUNITY AND END THIS
DISEASE.
