The Approved Code of Practice complying with the USECHH Regulations, 2000 under the Occupational Safety And Health Act, 1994, establishes a hierarchy of control measures which the employer must use when controlling exposure to hazardous chemicals in the workplace. In. this connection, LEV systems are commonly used to remove hazardous gases, fumes, vapours and dusts from the workplace.

It is a requirement by DOSH that the engineering control equipments or systems (LEV) be inspected at least annually besides monthly checking and recording internally.

EST provides the service of examining and testing LEV for their effectiveness by well-trained hygiene technicians. Every inspection conducted is properly documented and presented to meet the DOSH requirements.

Health Act, 1994 requires the employer to make a comprehensive assessment of the risk of exposure of employees to hazardous chemicals in the workplace. Chemical Health Risk Assessment (CHRA) is a cornerstone by which compliance with the Regulations is achieved.

EST offers a complete CHRA compliance service from initial risk assessment of exposure to hazardous chemicals in the workplace, to providing advice on current control measures in use and carrying out workplace and personal exposure monitoring (as a quantitative assessment of control).

Since the introduction of the Environmental Quality (Clean Air) Regulations, 1978, operators of industrial facilities are required to submit emission data to the Department of Environment and relevant local authorities as proof of compliance with the statutory limits under the regulations concerned. EST provides competitively priced stack emission monitoring services using internationally recognized protocols that are conducted by qualified and trained staff.

We have extensive experience in monitoring stack flue gases. Our capability includes testing the following parameters:

1. Concentration and mass emission of particulate using isokinetic sampling techniques

Various measurement techniques have been developed for the assessment of noise emission from single or multiple sources such as industrial plants, railways, road vehicles, aircraft or construction activities as result of research on the impacts of noise on human being. EST has the capability to conduct various type of noise survey and measurement to meet the different requirement from the enforcement authorities, industries and consulting firms. The service that EST offer include:

1. Measurement of overall environmental noise at site arising from multiple noise sources. Measurement parameters include:
   1. equivalent continuous sound pressure level LAeq
   2. maximum level LAmax
   3. minimum level LAmin
   4. percentile level Lax (LA5, LA10, LA50, LA9O, LA95)
   5. instantaneous sound pressure level, Lp
2. Measurement of sound pressure levels of gas turbines or other machineries installed at specific location or within buildings. This serves as compliance measurement as well as part of the impact evaluation on environmental noise.
3. Measure of sound frequencies and pressure levels for a specific environment or equipment or a combination of different equipments for abatement purposes. The objective is to identify offending sound frequency range(s) that is responsible for high noise level.

Soil is often contaminated at industrial site by various chemicals used or end product from production process, particularly at the storage and production facilities of a plant. Some of the contaminants are not only retained in the top soil but also penetrate through it, reaching the groundwater level. Therefore, it is imperative that investigation to determine the degree of soil and ground water contamination for a suspected contaminated site be conducted.

Baseline soil and groundwater survey is normally conducted before the occupation of a site for industrial purpose. EST offers the following scope of site sampling and measurement as well as laboratory testing pertaining to soil contamination and sub-soil gas measurement.

1. Sampling of soil and sub soil to determine the extent of contamination
2. Analysis of soil and sub-soil samples for various types of contaminations
3. On-site measurement of sub-soil organic gases using pre-calibrated portable meters
4. Sampling of sub-soil gases for further laboratory analysis

Groundwater study is essential to determine the existing quality of groundwater at a designated site. Baseline groundwater survey is normally conducted before the occupation of the site for industrial purposes. Subsequent and continuous monitoring of groundwater after occupation of site is an important step to evaluate and detect contaminant(s) that might penetrate through the ground and reach the groundwater level.

EST provides the following services for groundwater study:

1. Permanent groundwater well installation using established protocol
2. Purging of groundwater well and sampling of groundwater for various targeted contaminants using different techniques/protocols and equipments/accessories
3. Appropriate preservation and handling of groundwater samples using chain-of-custody
4. Conducting analysis for various types of targeted organic and in-organic contaminants using established analytical procedures

Vibration and sound are generated during rock blasting, construction, passing train and aircraft landing and taking off, etc. Vibration and sound generated from the source are propagated spherically like an elastic wave in the ground and the amplitude diminishes inversely as the distance advance from the initial spot of event. Certain amplitude of vibration and sound experienced by human can be very uncomfortable and damaging to properties.

EST is capable of carrying out vibration and sound measurement at carefully selected sites using seismography during events that generate vibration and sound for the following purpose:

1. Quantitative measurement that provides and indication of what vibration and sound levels can be expected and therefore the appropriate abatement to be taken to rectify the situation
2. Quantitative measurement that provides the industries or local authority a better understanding of the reasonable vibration and sound expected, so that any future contractual agreement or regulations to be considered may be realistic

Fugitive emission of hydrocarbons is common in the petroleum based industries. In order to reduce the impact of fugitive emission on the environment as well as to minimize product losses, hydrocarbon leak detection survey using intrinsically safe equipment is essential to produce data that can be used to identify and quantify emission sources within the plant.

EST has the expertise to carry out fugitive emission survey for the following purposes:

1. Minimizing valuable products loss, reduces costs and maximizes profit
2. Satisfying the corporate as well as local authority requirement for reduction of emission to ambient air.

Since the introduction of the Environmental Quality (Sewage And Industrial Effluents) Regulations, 1979, operators of industrial facilities are required to carry out compliance testing for treated wastewater and submit analysis data to the Department of Environment on a regular basis. For industries that are in need of a wastewater treatment plant or require upgrading of an existing treatment plant to handle a larger wastewater load, wastewater characterization study is conducted to determine the quantity and quality of the wastewater for designing or upgrading of wastewater treatment plant.

Monitoring of surface water (river, stream, pond, etc) and marine water is very often required as part of the Environmental Impact Assessment (EIA) study for a proposed project as well as meeting the requirements stipulated in the EIA approval during project implementation later.

EST is fully equipped and has extensive experience in conducting wastewater characteristic study, wastewater sampling for compliance purpose, various types of surface water sampling and marine water sampling using appropriate types of equipments, tools and sampling devices.
