What is the first step in controlling visible emissions in cremation?

The first step in controlling visible emissions in cremation is evaluating the materials to be cremated. This step is crucial because the types of materials being burned significantly impact the emissions produced during the cremation process. Certain materials can produce more particulate matter, toxic substances, and other emissions that can be visible. By conducting a thorough evaluation of the materials, operators can identify potentially problematic items that may lead to increased emissions. This proactive approach allows for better planning and management of the cremation process, ensuring compliance with environmental regulations and maintaining air quality standards.

In this context, the other actions like monitoring emissions, adjusting the retort temperature, and controlling the furnace pressure are important aspects of the overall emissions control strategy but can only be effectively implemented after a clear understanding of what is being cremated. Without the initial evaluation of the materials, those subsequent steps might not be adequately tailored to address specific emissions issues.
