5.12 List of Best Practices
Some of the techniques described as air abatement techniques which can be installed in enterprises for air pollution minimisation include:
Cyclones Dust Collector at the point of air pollution origin
Bag Filters

Wet Scrubbers at the stack
Apart from these methods, the company/ facility should have a dedicated air quality professionals (part/full time) who can work to minimize the impact of air pollution on workers. The best practices that can be followed in the enterprise are:
Having Management Commitment
Management commitment is essential for continuous and long-term efforts.
Follow Collaborative Approach
The best way to successfully implement an initiative is to get the whole team behind it. It is essential to provide them the necessary training on standard operating procedures and need to do such project which will help them to know the purpose of starting such projects.
Set Targets
A well-defined target for a particular timeframe is needed to be established for continual improvement in the system. Communicate with others what you want to achieve. For example, to decrease the amount of carbon dioxide inside facility by having indoor plants inside facility.
Spreading and speeding up technology transfer
It is essential to be well informed about the latest technologies and to implement them wherever possible for minimizing the effect of air pollution on environment and health. Also, make others informed about the same for spreading awareness.
Behavioural Change
Attitude is important when you are trying to bring a necessary change. Working in a team with staff become easier by understanding their attitude and then implementing solutions. To reduce the impact of indoor air pollution, workers should
