At least 100 firefighters from multiple departments battled back-to-back blazes at two New York businesses Wednesday.

The first fire broke out at the Ole Vi bar just after 8:15 a.m., WKTV-TV reports. A second incident—at heavy equipment repair shop Altrux—happened while crews were still tackling the fire at the bar.

Fighting the Altrux fire also proved difficult for crews. Because the building was made of steel, firefighters had trouble opening and venting the roof, according to WKTV.

No one was hurt in either incident. Investigators are trying to determine the cause of both fires.
