This image shows a person operating a fuel-powered machine in a small, enclosed space with no visible ventilation. The machine emits thick exhaust fumes, which rapidly fill the area. This creates a serious risk of carbon monoxide poisoning, as exhaust gases from internal combustion engines contain toxic fumes that can be deadly when inhaled in confined spaces.

The key issue here is the lack of proper gas flue systems or ventilation. Any equipment producing combustion gases must be used in well-ventilated areas or connected to appropriate flue systems to redirect harmful emissions outside. Without these controls, workers are at risk of suffocation or long-term respiratory damage. Training and signage are critical in ensuring workers understand the danger of using such equipment in tight or enclosed spaces.
