Occupational Hygiene V/S Environmental Engineering Purpose Occupational Hygiene is about Measuring of levels of exposure to hazards and the Establishment of an Occupational Hygiene measurement system that is 1.Appropriate considering hazards 2.Provides accurate and reliable information to the employer for proper intervention 3.Ensures correct record keeping and that can be used by Medical Practitioner Environmental engineering is about using hygiene records to design systems that eliminates or reduces exposure of employees to the hazards by engineering or administration methods.

Main Responsibilities of a Hygienist or Environmental Engineer at mines Ventilation – Removal or Dilution of Airborne pollutants and supply of Oxygen Noise – Prevention of Hearing loss Heat – Prevention of Heat related incidents Illumination – Improvement of vision Ergonomics – Body stresses related injuries and delayed health problems Dust – Prevention of Pneumoconiosis (Lung Diseases Hygiene – Chemicals/Germs/disease free environment/fatique Emergency preparedness and response

Legal Appointments Section 12.(1) Part time or Full time Occupational Hygienist or Environmental Engineer Qualifications –Certificate in Mine Environmental Control or –Intermediate Certificate in Mine environmental Control coupled with being certified as and Occupational Hygienist by the South African institute for Occupational Hygiene.

Governing MHSI Regulations Chapter 5 (Fires and Explosions) –Prevention and suppression systems for coal dust and flammable gas –Prevention, detect ion and combating the start and spread of mine fires –Transportation, storage, deposit and disposal of flammable liquids, gas and materials Chapter 17 –Emergency/Evacuation plans

Governing MHSI Regulations Continue Chapter 9 (Environmental Engineering and Occupational Hygiene) –Safe use of compressed air –Efficient Early warning devices –Ventilation control devices safety –Ceased working places safety –Hygiene Establishment of hygiene measurement system( Airborne pollutants, gases and vapors, thermal stress and noise Portable and palatable water Ablution and change house facilities. Clean working clothes Correct respiratory equipment Proper Illumination

Governing MHSI Regulations Continue Chapter 16 (Rescue & First Aid & Emergency preparedness & response –Self Contained Self rescuers Sole allocation Maintenance Monitoring programme Record Keeping –Mine First Aid/Evacuation/Rescue Teams readily available

Governing MHSI Regulations Continue Chapter 22(qualifications, skills and affiliations) –22.15(5)(a) for chapter 5 –22.15(9)(a) for chapter 9 –22.15(16)(a) for chapter 16

Challenges Facing the Mines Inadequate systems results in: –Mental Stresses –Physical Stresses –Psychological Stresses –Poor Health –Accidents What most mines do not realize is that poor environmental conditions contributes a lot to poor productivity as this also affect machinery and Equipment as well as working place safety.

Linking of Medical records The purpose is to assist the Medical practitioner to conduct risk analysis and to ensure that proper diagnosed is done prior or after exposure of individuals. The following is important: –Health hazards to be communicated to the Occupational Medical Practitioner –The aim is to prevent, detect or properly treat occupational diseases.

Challenges Part Time Occupational Hygienist referred to as Consultants(presence and service) Poor risk assesments Health issues are delayed and not quickly diagnosed like safety hence don’t get correct attention. Dedicated, Committed, Determined, Unsupervised, Assertive Qualified and skilled Hygienist? Poor empowerment of Hygienists and support at mines. Small mines appointing illegal immigrants and high turnover and no surveillance or hygiene measurements Mines (especially small ones)knowledge of the service requirements from Hygienists they appoint Submission of correct reports to the office Data capturing and analysis Reliability of reports and records submitted.

Main Deviations Poor ventilation conditions. –Fan/Column distance to face –Ventilation curtains distance to face –High temperatures –Blasting schedule signed by Hygienist –Evacuation plans –Emergency plans –Use of GDI’s and how to measure airflow –Lamp room systems –Codes of practices applicability Change houses and Ablution facilities
