A fire on Jan. 31
at the Winston Weaver fertilizer terminal on the north side of Winston-Salem,
N.C., completely destroyed the facility and prompted a three-day evacuation
order for residents and businesses within a one-mile radius of the plant due to
concerns about a possible explosion triggered by ammonium nitrate stored at the
site.
The fire was first
reported by a passerby at 6:45 p.m. on Jan. 31. According to city officials,
only one of the plant’s 36 employees was onsite at the time of the 911 call,
and all employees were safe and accounted for.
Firefighters fought the blaze for 90 minutes before pulling back from the site after they observed what they believed was off-gassing from a railcar onsite that contained 90 tons of ammonium nitrate. The 65,423-square-foot warehouse at the facility, which was engulfed in flames, reportedly contained another 500 tons of ammonium nitrate, as well as a reported 5,000 tons of finished fertilizer products.
The City of
Winston-Salem then issued one-mile evacuation zone around Weaver’s 4440 North
Cherry Street address, affecting almost 6,500 residents, or 2,497 households.
“Don’t wait for something to happen,” the city posted on Twitter. “Something
has happened. Now is the time to get out.” Residents were reportedly alerted
through a reverse 911 call, as well as from public address systems on fire
trucks navigating roads within the evacuation zone.
The evacuation
order also affected nearby Wake Forest University, which cancelled classes on
Feb. 1 and then extended the cancellation to Feb. 2-3 after authorities
continued to warn of a possible explosion as the fire burned itself out. More
than 200 minimum security inmates at the Forsyth Correctional Center were
evacuated as well.
“Ammonium nitrate
has a history of being unpredictable in the way that it reacts to heat, the way
that it responds to pressure, to shock. It is sort of an enigma, and we are
giving it due regard because of its history,” said Winston-Salem Fire Chief
William “Trey” Mayo at a press conference on Feb. 2. “At the beginning of this
incident, there was enough ammonium nitrate on hand for this to be one of the
worst explosions in U.S. history.”
Mayo said 90 firefighters and approximately
150 personnel from other agencies responded to the blaze, including hazmat
teams to monitor air quality. The 8.46-acre site belched thick smoke throughout
Feb. 1-2 as authorities used an unmanned ladder truck to pump water on the site
and employed drones and helicopters to monitor the smoldering fire.
Representatives from some 25 local, state, and federal agencies were reportedly
onsite to monitor events.
While an initial
estimate suggested the evacuation order would be reevaluated in 36-48 hours,
Mayo on Feb. 2 said the city would maintain a “firm stance” on the one-mile
evacuation radius for an “undetermined time.” North Carolina Gov. Roy Cooper
was also on hand for a press briefing on Feb. 2.
A weather change
on Feb. 2-3 brought rain and colder temperatures to the Winston-Salem area,
however, which helped extinguish the flames and lower the danger of a potential
explosion. At midday on Feb. 3, Mayo told reporters that the risk of an
explosion had “greatly diminished,” and firefighters working in groups of 12
and wearing protective gear were beginning to work at the site.
Helmet-cam footage
from one of the firefighters showed charred rubble, twisted wreckage, and an
utterly gutted facility, with little evidence of any remaining fertilizer
products. Mayo said discussions were underway on how to safely remove the
railcar, but crews were able to inspect the car and observed that the ammonium
nitrate inside was “dry, white, and granular, as we expect it to be,” he said.
At 4:44 p.m. on
Feb. 3, the city announced that the evacuation order would be reduced to a
radius of 660 feet as of 8 p.m. that evening. With no houses located within the
reduced zone, the Winston-Salem Journal
reported that all residents would be allowed to return to their homes.
Winston Weaver is
owned by Meherrin Fertilizer Inc., Four Oaks, N.C. Meherrin’s website lists the
Winston Weaver facility as one of approximately two dozen terminals operated by
the company in the Eastern U.S. The website describes Winston Weaver as a
manufacturer of Weaver Ammoniated Fertilizer and a handler of potash, DAP,
K-Mag, and blended fertilizer.
Winston Weaver’s website
said the company was founded in 1929 and the plant was built in 1939, officially
opening for business in January 1940. The list of bagged fertilizer products
sold under the Weaver brand include 34-0-0 for lawn and gardens, 27-4-7
slow-release fertilizer, pelletized limestone, and “all purpose” plant food
products sold in 8-8-8, 10-10-10, 13-13-13, and 17-17-17 blends. Local news
reports said the company is a bagged fertilizer supplier for Lowe’s
home-improvement stores throughout the Southeast.
The cause of the fire remains under investigation. Attempts by Green Markets to reach Meherrin Fertilizer or Winston Weaver for comment were unsuccessful. The Winston-Salem Journal reported that the facility passed a fire inspection as recently as December 2021, with no hazards or violations reported. Mayo said the building was not equipped with fire sprinklers.
Winston Weaver
announced that it is contributing $100,000 to help the city recover from the
fire. Company representative Andrew Carroll spoke with reporters on Feb. 1,
confirming the safety of all 36 employees and the company’s commitment to their
security. “We’re going to continue to take care of them,” he said.
“In the next few days, we’re going to stay here and work with the
EMS first responders, working closely every hour,” he added. “We have people on
the grounds here with EMS, trying to explain exactly what’s where in the plant
and just be as much help and provide as much information as we can. We will
continue to work with the community and the people who have been displaced.
That’s our number one goal, which is to take those who have been displaced and
get them back in their homes as fast as possible.”
Carroll spoke with reporters again on Feb. 3. “We met with all 36
employees today, and we’re going to pay those employees for a month,” he said,
noting that some had been with the company for more than 30 years. “And we’re
helping them get jobs. Some of them have already been placed in jobs with other
industries similar to Winston Weaver. We’re just going to work with them and do
the best we can to support them.”
Carroll also expressed gratitude to the company’s customers,
suppliers, and competitors for offers of help and support. “The support that we
felt from our customers, our suppliers, and even our competition has really
showed us how much of a family-owned business this feels like, and how much
support that we do have in the community,” he said.
The Fertilizer Institute (TFI), which was hosting its Annual
Business Conference in Orlando, Fla., when news of the fire broke, issued a
statement on Feb. 2 saying its “thoughts and prayers are with the citizens and
first responders” in Winston-Salem.
Kathy Mathers, TFI Vice President, Public Affairs, told Green
Markets that the trade association had been “facilitating the sharing of
industry technical expertise on ammonium nitrate with local emergency
responders” in Winston-Salem. “We are fortunate to have members who have been
quite generous in this regard,” she said.
“Different members of our team have been in almost constant contact
with the folks at Weaver to help share any and all information that may be
helpful,” added Jason Troendle, TFI’s Director, Market Intelligence and
Research.
The August 2020 explosion in Beirut, Lebanon, and the deadly 2013 ammonium nitrate explosion in West, Texas, were front and center in the minds of emergency responders in Winston-Salem.
“The quantity of ammonium nitrate they had on hand
(in Texas) was 240 tons. When this fire began last night, we had 600 tons on
site,” Mayo said. “So, if that doesn’t convey the gravity of this situation and
how serious folks need to take it, I don’t know how else to verbalize that.”
