Leaving heat sealing equipment on unattended is not a safe practice due to the inherent risks associated with heat and potential hazards of malfunction. Heat sealing equipment is designed to operate safely only when monitored, as it can reach high temperatures and poses fire risks. Unattended equipment could lead to overheating, equipment failure, or unsafe conditions that could endanger personnel and the surrounding area.

In contrast, the other options represent standard safety practices. The use of personal protective equipment is critical to ensure that individuals are protected from potential injuries when working in environments where explosives or hazardous materials are present. Proper signage is essential for communicating risks and maintaining awareness of safety protocols, while regular equipment checks are necessary to ensure that all machinery is functioning correctly and safely, preventing accidents and ensuring compliance with safety regulations.
