Engines that power portable pumps and compressors are required to be equipped with exhaust system spark arresters due to safety and regulatory reasons. Spark arresters serve to prevent sparks generated by the engine's exhaust from igniting flammable materials in the surrounding environment. This is particularly crucial in outdoor settings where combustible materials may be present, potentially leading to fires.

It ensures compliance with safety regulations that aim to minimize fire hazards associated with engine operations, especially in areas where flammable gases or materials are prevalent. The necessity for such precautions highlights the importance of proper safety equipment in preventing environmental and operational hazards when using combustion engines in various applications.

While standard mufflers are typically installed on engines to reduce noise levels and improve performance, they do not provide the necessary protection against sparks. Unshielded ignition systems could pose a risk of igniting flammable materials, and normal ignition systems do not address the spark hazard either. Hence, the focus on spark arresters is essential for maintaining safety standards in such operations.
