Why should businesses test air quality?

Air quality can affect employees, visitors, production environments and surrounding communities.For industrial facilities, air-quality assessment can provide information about pollutants generated by processes, equipment, combustion or other activities. The CEA manages ambient air quality and stationary-source emission control under Sri Lanka's environmental framework.

What pollutants can be measured?

Depending on the purpose of the assessment, air quality testing may consider:

Particulate matter
Carbon monoxide
Sulfur dioxide
Nitrogen dioxide
Volatile organic compounds
Ozone
Other relevant pollutants

IW Labs lists several of these pollutants within its air quality testing service.

Indoor vs outdoor air quality

Air quality testing should begin with the question:

Where is the concern?

Indoor workplace assessments may focus on the conditions employees experience inside buildings. Outdoor or ambient assessments may focus on environmental air quality around a facility.Industrial emission testing, meanwhile, focuses on specific emission sources such as stacks.These are related but different assessments.

When should a factory consider air quality testing?

Businesses may consider testing when:

Introducing a new production process
Investigating unusual odours
Reviewing ventilation
Assessing workplace conditions
Evaluating pollution-control systems
Establishing baseline conditions
Supporting environmental monitoring
Why regular monitoring can be useful

One measurement provides a snapshot.

Repeated monitoring can provide a trend.

Trends may help identify changes associated with:

Production volume
Seasonal conditions
Equipment changes
Maintenance
Process changes

IW Labs describes its air-quality service as supporting customized testing and monitoring, including real-time monitoring applications.

Choosing the right air-quality test

There is no universal test panel suitable for every workplace.

The right parameters depend on:

Industry
Process
Potential contaminants
Indoor/outdoor environment
Regulatory requirements
Monitoring objective
