Sampling and Health, Safety and Environment Standard Operating Procedures for GHG emissions measurements from On-Site and Small-scale Sewered Sanitation Systems

This Sampling and Health, Safety and Environment (HSE) Standard Operating Procedure ensure that fieldwork surveys aimed at measuring greenhouse gas (GHG) emission measurements from sanitation systems across different sites are conducted accurately, consistently and safely. This document outlines procedures for pre-fieldwork preparations, on-site sampling and post-fieldwork activities, covering both on-site and decentralised/small-scale sewered site locations. Considering that fieldwork involvesintensive onsite sampling and handling of potentially hazardous biological and chemical substances and mechanical risks from handling equipment on site, we have identified key focus areas including personal safety, data integrity and equipment preparation and handling. This standard operating procedure was produced based on the research activities conducted as part of the EMISI project in Indonesia.
