Environmental pollution monitoring
This includes indoor and stack monitoring. Indoor monitoring may be necessary to comply with the requirement of the COSHH regulations for monitoring of the exposure levels of personnel to hazardous substances including fumes, dusts and gases. Monitoring methods used are based on current HSE preferred techniques.
Environmental Protection Legislation (EPA 1990) requires emissions from stacks to atmosphere to be monitored. This includes monitoring of
VOCs, gases and particulates (e.g. iso-kinetic sampling) from stacks. Other parameters such as duct and stack velocity are also included. An on-going
programme can be arranged.
LEV measurements and design . and design
A legal requirement under the COSHH regulations is the testing and maintenance of all control measures used to reduce exposure to hazardous substances. ESL can design Local Exhaust Ventilation (LEV) systems for controlling airborne contaminants and can carry out the necessary regular testing of such systems in accordance with the HSG 258. Measurements will include face velocity, static pressure, duct velocities, pressure differential across filters, air temperature, fan speed etc.

Airflow measurement and modelling
The overall amount of air entering and leaving a building is
of fundamental importance in assessing the working
environment. The traditional way of determining air movement
is to measure the bulk of airflow through the area. ESL can
carry out not only the airflow measurement but also modelling of airflow in a building. Such
modelling enables areas of
thermal comfort, dead zones, and draughty areas to be
identified quickly so that appropriate improvements can be
put in place.
Indoor air quality (IAQ)
The adverse publicity, absenteeism and reduced productivity
associated with Sick Building Syndrome (SBS) has highlighted
the need for improved air quality. To help ensure that air
conditioning / handling systems provide, and continue to
provide, a hygienic and quality indoor air supply, ESL can
offer the following range of services:
|
| >
Surveys and risk assessments of air
handling units |
| >
Ventilation and thermal environment
surveys |
| >
Routine monitoring of indoor air quality |
| >
On-going monitoring programmes to meet
specific client needs |

Laboratory analytical
services
ESL has a special relationship with a number of Laboratories
who specialise in analytical chemistry and have NAMAS
accreditation. Analytical techniques available from this
service include Gas Chromatography, HPLC etc. ESL can also
arrange toxicological testing in conjunction with an
associated laboratory.
