The role of an Environmental Control Officer (ECO) is basically to look out for conditions/ situations in construction sites which cause environmental health problems or are likely to cause environmental health problems. He should report these conditions/ situations to the contractor together with recommendations on remedial measures to be taken to prevent recurrence.
The main areas where the ECO should pay attention to are as follows:
- disease-bearing insects and rodents
- proper disposal of construction waste/ marine clay
- noise, air and dust pollution
- earth littering
- siltation of drains
- food hygiene in canteens
- any other environmental health matters
