INDUSTRY HYGIENE MONITORING AT JB COCOA SDN BHDINDUSTRY HYGIENE MONITORING AT JB COCOA SDN BHD
JB Cocoa Sdn. Bhd. Is a cocoa processing plant in the Port of Tanjung Pelepas (PTP), Johor that operated since 2002. In 2003, JB Cocoa was commissioned the plant and commenced production, sales and export of cocoa ingredients namely cocoa liquor/ mass, cocoa butter, cocoa cake and cocoa powder. Presently the plant is operating at annual production capacity of 60,000 tones of cocoa bean equivalent. The plant is mostly operated 24 hours daily (production lines) with 237 workers including top management, technician, engineer, general workers, safety and health officer and administration staff. JB Cocoa was operated in compliance with the world-renowned quality and food safety standards namely ISO9001:2008 and HACCP (Ministry of Health Malaysia).
The industrial hygiene and environmental monitoring program was initiated to :
1)Monitor the industry hygiene and occupational safety & health properties in JB Cocoa Sdn Bhd;2)To verify compliance with the appropriate environmental standards and guidelines;3)To suggest the preventive and control measure.

HAZARD MEASUREMENTHAZARD MEASUREMENT
INDUSTRIAL HYGINE MONITORING HAZARD MEASUREMENT
1) AIR MONITORING
Using TSI DustTrak II, TSI QTrak, ppb RAE 3000
The parameter monitored are Particulate Matter (PM10), Carbon monoxide (CO), Carbon dioxide (CO2) and relative humidity (RH).
Workers are potential in exposed in emission of contaminants from the activities such as : i)dust from dumping, filling and palletizing process ii)combustion gases from heating process
2) NOISE MONITORING
Using Sound Level Meter TENSMAR TM-101
The measurement was taken at the dumping area in warehouse, control room and palletizing.
Workers are expose to high noise produced from: i)cocoa bean dumping processii)silo and grinding process (in control room)iii)palletizing work
3) LIGHT MONITORING
Using Light Meter-CENTER 337
The measurement was taken at the palletizing area and warehouse.
i) Working in warehouse and palletizing area was expose to accident with the forklift

1) For indoor air quality monitoring, it is found that carbon monoxide concentration, carbon dioxide concentration, particulate matter (in the control room) are not exceeded the acceptable limit as stipulate in ICOP IAQ 2010 (CO = 10 ppm, CO2 = C1000 ppm, PM10 = 0.15 ppm & RH = 40 – 70%).
2) The relative humidity is required to be between 70 – 80% because it is a suitable quality control measure for the cocoa product, however it is over the acceptable range as stipulate in ICOP IAQ 2010. Thus it is recommended that regular cleanliness measure is done to eliminate mould if existed.
3) The source of PM10 in the warehouse and palletizing area is due to cocoa bean dust and boxes dust. It is recommended to switch on exhaust fan ventilation at all time, ensure cleanliness regularly and equipped staff with appropriate PPE.
4) For the noise exposure, only noise exposure monitored in the warehouse exceed the action level as stipulate in regulation, however all of the volumes are not exceed the permissible level for 1 hour. It is suggested that appropriate PPE is applied by the worker in the warehouse.
5) Only light in palletizing area is lower than the standard stipulate by the regulation. It is recommended to ensure all lamp and other lighting device is in functioning status and clean at all time. Dust which tampered the surface of the lamp must be wipe off. Additional lighting sources may be required.
