What started as a routine workday at California’s environmental headquarters turned into a street-side scramble, as CalEPA employees say Tuesday’s evacuation was botched after contractors hit a gas line outside the downtown tower. Roughly 1,000 people were forced out to the sidewalks and one worker ended up being treated for chemical-exposure symptoms. Staff describe muddled public-address announcements and slow, shifting instructions that left the whole response feeling far more chaotic than it needed to be, ramping up pressure on state facility managers to explain what went wrong and how they plan to fix it.
What happened
Contractors working on a nearby downtown development struck a two-inch plastic natural gas main near 11th and H streets, triggering a Level 2 hazmat response and the evacuation of the Joe Serna Jr. CalEPA building along with two nearby motels, according to CBS Sacramento. Pacific Gas & Electric crews cut off the gas flow in roughly 45 minutes and stayed on scene while firefighters checked air quality. The California Underground Facilities Safe Excavation Board has opened an investigation into how the gas line was struck.
Employees say alarms failed and instructions were unclear
Inside the 25-story tower, workers say the first intercom message was so vague it did little to guide anyone, and that by the time an official email finally landed in inboxes, many people were already crowding stairwells or had reached the street. Building engineers say they shut down air-intake vents at 1:30 p.m. and met Sacramento Fire crews outside at 1:45 p.m., and that a chief engineer later sent out a clearer evacuation announcement. The Department of General Services, which now manages the building, says the team plans to test the public-address system on Sunday to make sure it is functioning properly, according to The Sacramento Bee.
One worker treated
Longtime employee Laura Fisher, who lost her sense of smell after COVID-19, said she never noticed the gas odor. After evacuating, she developed shortness of breath and vomiting, went to urgent care and was then transported to a hospital. “None of those things happened on my floor,” Fisher told reporters, referring to missing visual and audible alarms, as reported by The Sacramento Bee. Fisher, who has worked in the building for more than 20 years, said emergency responses have felt disorganized since facilities management shifted to DGS in the 2023–24 fiscal year.
Investigation and legal questions
The gas-line strike is now under review by the California Underground Facilities Safe Excavation Board, which enforces state excavation rules and can investigate whether required notices and locating procedures were followed. The board operates under the state’s Office of Energy Infrastructure Safety. Investigators have interviewed workers who were on scene and are examining how the line was hit, and the probe could result in enforcement actions or updated excavation guidance, according to the state’s Office of Energy Infrastructure Safety.
What to watch next
CalEPA communications say alarms did activate and that the evacuation unfolded in line with staff training, while a post-incident review team looks at response times and what additional safety supports employees might need. Workers say they will be watching closely for the excavation board’s findings and for any concrete changes to building protocols and emergency communications once the dust settles.
