The fire led to an explosion of aerosol containers and the burning of approximately 600 square meters of the site on July 1.
Firefighting efforts were hampered by strong winds.
Two of the 10 injured individuals were seriously hurt and were transported to nearby hospitals. Specialized burn treatment was also needed, with some patients taken to a center in the southern city of Siemianowice Śląskie.
"The findings so far do not indicate arson or other foul play," said Jolanta Szkilnik, a spokeswoman for regional prosecutors.
"There was no contamination of the air or groundwater in the affected area," she added.
