Odour Survey & AssessmentOdour Survey & Assessment

Nuisance Odour remained as one of common complaint which local regulators received. The majority of air pollution complaints are related to nuisance odour. The issues normally will become complex when the sources and types of odour unable to be found and recognized.  Furthermore, odour may be subjective as the human perception of odour may be varied from person to person.  Odour can be measured as odour strength and quantified as Odour Unit (OU) using standard method as published by the American Society of Testing and Materials (ASTM E679 and E544) and by the European Union (EN13725). In 2000 the proposed European Normalization Standard, EN 13725 implemented and become the “International Standard” for odour testing. The odour unit will scale how strong the smell in the air samples collected by dilution/threshold (D/T) principles with using of olfactometer.  Odour results reported in the Odour Unit or Standard Odour Unit might be less useful if lack of local odour regulation to compare the results obtained. A more detail chemical analysis often necessary to determine the odourous compounds that contributing smell in the air. Odour detected by the human nose typically will be nuisance and in most of the cases do not cause long term health effect to the individual as the concentration level of odourous compounds could be possibly lower than TLV as stipulated by ACGIH.  Generally, if the sources of odour able to be identified and eliminated, any related sickness (eg nausea) will be disappeared.  Odour Analysis: We have several state of art technology able to help you to identify the chemical compounds responsible to the odour and trace the possible sources of odour.

Occupational Hygiene

What is Occupational Hygiene? The International Occupational Hygiene Association (IOHA) refers to occupational hygiene  (in US ‘Industrial’ Hygiene) as the discipline of anticipating, recognizing, evaluating and controlling health hazards in the working environment with the objective of protecting worker health and well-being and safeguarding the community at large. The workplace hazards may result in injury, illness, impairment, or affect the well being of workers and members of the community. We have competent person that able to assist you in measure the chemical & noise exposure as well as assess the Risks Evaluate Health Effects due to Hazardous Substances & Noise.  Our Hygiene Monitoring Services as listed below:
