An
update on their condition was not immediately available. The
city canceled a shelter-in-place order in the afternoon that had
affected several nearby industrial plants, officials said.
The La Porte Office of Emergency Management (LPOEM) said the
Fire Department and Harris County Pollution Control confirmed
there were no "detectable amounts of immediately hazardous
products" near or downwind the facility.
Officials had cautioned residents to shelter in place due to a
phosgene gas leak at Altivia, a chemical manufacturer and
transporter that develops phosgene derivatives for
pharmaceuticals and the agriculture industry.
"Eight people were transported from Altivia due to exposure, and
all were stable at the time of leaving the facility," said
Harris County Judge Lina Hidalgo, the county's top executive, in
a social media post on X, formerly known as Twitter.
"This happens quite frequently, we aren’t surprised," said Ana
Parras, executive co-director at Texas Environmental Justice
Advocacy Services. "What they are producing is chemicals for
plastic production, and there has been a rise in incidents" at
Texas chemical plants.
The leak was the result of a ruptured pressure release device,
Altivia said in a statement. All processes at its La Porte
facility have been shut down, and its personnel contained the
leak, the company added.
Phosgene is a colorless gas with a suffocating odor like musty
hay that is used in the manufacture of other chemicals,
pesticides and pharmaceuticals, according to the U.S. Centers
for Disease Control and Prevention.
Exposure to phosgene gas may cause vomiting, breathing
difficulty, chest pain and, in its liquid form, frostbite.
Halliburton's Multi-Chem Bayport site, Stepan's Pasadena
facility, and three other sites belonging to Kuraray America,
Evonik and NCTI lifted orders to shelter in place, according to
community alerts.
