Carlsbad Caverns National Park – Carlsbad Caverns National Park visitor
center and cave tours reopened Wednesday at noon following extensive air
quality testing by industrial hygienists. The temporary closure began
Monday afternoon as a precaution after it was discovered that vapors from
chemicals used by contractors renovating the park's elevators had seeped
into the park’s visitor center.
“Three industrial hygienists toured the building this morning, and tested
air quality with two separate sets of instruments,” said Carlsbad Caverns
National Park Superintendent John Benjamin. “With their precise test
results and after consultation with safety experts, we are confident the
air quality is safe for visitors and employees.” The health and safety of
visitors and employees is critical, and reopening facilities depended on
concerns being mitigated.
The chemicals that were the source of the vapors were being used as part of
a complex project renovating the primary elevators. This phase of the
project involves the installation, adjustment, and cleaning of the guide
rails and brackets, which ensure smooth, safe elevator operation. Some
employees reported being affected by the vapors and sought medical care,
were treated and released. At this time we don't believe there was any
harm to the cave resources or wildlife; park staff will be looking for any
impacts.
