Before Smoke Returns

Quick Answer

Review the last smoke event while people still remember it. Identify the jobs and work areas where exposure was hard to control. Find out what the building’s filters and outdoor-air settings can actually do. Write a plan that names who checks the air, who can change the work, and how employees hear about it. Finish the equipment work and the training before the next smoke event arrives.

You do not need a forecast for next year’s fire season. You need a workplace that can act when the air becomes unhealthy.

Prepare for Wildfire Smoke After the Air Clears

When the sky clears, the pressure to do something about it tends to clear with it. Employees stop asking about air quality. Outdoor work goes back on the usual schedule. Facility managers move to the next problem on the list.

That is also the best time to prepare. The unanswered questions are still fresh, and nobody is making decisions in a parking lot at 6 a.m. because the AQI jumped overnight.

Reno, Sparks, and the rest of Washoe County already had that test this year. Northern Nevada Public Health issued an August 10, 2026, air quality advisory for Reno and Sparks because of regional wildfires. Later fires, including the Hawk Fire on Peavine Peak, put the same problems back on the table. Walk through how your site handled those issues. That review will help you understand what needs to happen before smoke returns.

Review What Happened During the Last Wildfire Smoke Event

Get facilities, operations, and environmental health and safety (EHS) in the same room while the details are still available. Bring the supervisors who ran the work and the employees who worked in the smoke. Ask what happened, what they did, and what they did not know.

The useful findings are specific. A supervisor could see a regional AQI reading and still not know what that meant at an open loading dock. Office staff reported smoke indoors, and nobody could confirm the ventilation settings. The person authorized to pull outdoor crews inside was out for the day.

Pull complaints, maintenance records, monitoring results, schedule changes, and employee notices. If a record is missing, decide what you will capture next time. Turn each unresolved question into an assignment with a name and a date.

What Air Quality Data You Need During Wildfire Smoke

Public air quality reports are a starting point, not a complete picture. For Reno, Sparks, and Washoe County, Northern Nevada Public Health’s Air Quality Management Division is the local source. If you have more than one site, name the right source for each location.

A county reading does not tell you the air in a break room or at a warehouse door. Before you buy monitors, decide what you need to learn. Are you checking whether a room is clean enough for breaks? Comparing an office with an attached warehouse? Seeing whether a filter change actually cut indoor particles?

An industrial hygienist can help decide whether monitoring is worth doing and how to read the results. The plan should name measurement locations, equipment limits, who reviews the numbers, and what happens when conditions change. A monitor is useful only when someone knows what to do with the reading.

FACS’s wildfire smoke FAQ covers indoor monitoring and its limits.

What Your HVAC System Can Do During Wildfire Smoke

Use the gap between smoke events to walk the HVAC system with people who know the equipment. Determine which filters the unit can take, whether those filters fit, how outdoor air is controlled, and what maintenance is overdue. Order compatible replacement filters before the next rush.

EPA’s guidance for schools and commercial buildings covers higher-efficiency filtration, portable air cleaners, ventilation, and building operation during wildland-fire smoke.

MERV 13 or better may be appropriate if the unit can handle the pressure drop. Cutting outdoor air still has to leave enough ventilation, hold building pressure, and keep other indoor conditions in line.

Write the plan for the way the property actually runs. A Sparks distribution facility that opens loading doors all day needs a different play than a downtown office. The warehouse plan has to cover deliveries and the occupied floor. The office plan may need a designated cleaner-air room that does not overheat or fill past capacity.

Test the proposed settings before an emergency. Write down the approved mode. Name who can change it on nights and weekends.

Plan Employee Work Around Wildfire Smoke

Review tasks, not just job titles. A maintenance employee may spend one day indoors and the next on a roof. A warehouse employee may work deep in the building or spend the shift beside an open door. Exposure depends on where the work is, how long it lasts, and how hard the work is.

Identify tasks that can be postponed, moved, or done differently when smoke gets worse. Decide where employees can take breaks in cleaner air. Make sure those changes do not create a heat, traffic, or fall problem of their own. NIOSH describes practical ways employers can cut outdoor workers’ smoke exposure.

Who Can Change Work When Wildfire Smoke Gets Worse?

Name who checks conditions and who can change the work. Name a backup for each job. Set response criteria that match the site, the controls you actually have, and the rules that apply in Nevada. Review those criteria before each season. Do not carry last year’s assumptions forward.

Nevada added a statutory wildfire-smoke duty for many outdoor employers in 2026 under Senate Bill 260. The Division of Industrial Relations (DIR) is still writing the detailed workplace rules. That is not a free pass. Employers still have to protect workers from recognized hazards, including unhealthy air. Use the rule that applies to the job site. Update the plan when the DIR package is final.

Employees need to know how to report concerns and where updates will come from. Prepare a short notice you can adapt: current conditions, what you are changing, and when the next update is due. Supervisors should know how to handle reported symptoms and when to get medical help.

Walk through a realistic scenario with the people who would have to act. Smoke worsens on the afternoon shift. Deliveries are arriving. The facilities manager has left for the day. Who checks conditions, who authorizes the change, and how do employees hear about it? Questions that stall the room are the work the plan still needs.

Keep Wildfire Smoke Damage Questions Separate

If odor, visible residue, or a possible smoke-damage claim is still open, get that evaluated on its own. A preparedness review does not close a property file. FACS’s structure fire and wildfire smoke assessments cover impact to buildings and contents and what to do next.

Use those findings to improve next season’s plan. Do not mix the cleanup decision with the workplace-readiness work.

Put Wildfire Smoke Improvements on the Schedule

A review is only truly helpful if it changes what happens next. Put dates on HVAC work, monitoring decisions, employee training, and a practice run of the response plan. Put the costs in the budget that will actually pay for them.

Before the next smoke event, confirm that:

• Approved filters and other supplies are on hand
• Monitoring duties and response criteria are written down
• Supervisors know which work they can change and that they have the authority to change it
• Employees know how to report concerns and where updates will appear
• The plan matches current Nevada requirements and has been tested against a realistic shift

The next smoke event may arrive under different wind, a different fire, and a different staffing pattern. Preparation gives the team a basis for acting without needing to make every decision on the spot.

Frequently Asked Questions

When should a Northern Nevada employer review its wildfire smoke plan?

Review your wildfire smoke plan after a smoke event, while people still remember the issues that occurred. Confirm equipment, duties, training, and current rules before the next season. Update the plan when the building or the work changes.

Does every workplace need indoor air monitors?

No. Monitoring should answer a defined question. A review of the building, the work, public air quality data, and earlier complaints will tell you whether a number would change a decision.

Can one smoke-response plan cover several locations?

You can use one framework. Each site still needs its own building facts, work activities, local air sources, and named people on site.

Does Nevada have a wildfire smoke workplace rule?

Nevada enacted Senate Bill 260 in 2025. The employer duty took effect in 2026. Detailed Division of Industrial Relations rules are still being written. Until those rules are final, protect workers under the statute and under the existing duty to address recognized hazards. Do not assume a California or Oregon AQI trigger is the Nevada trigger.

Should we wait for a severe-season forecast before spending money?

No. Base the work on how your site actually takes in smoke and on the gaps you already found. A forecast cannot tell you whether a particular warehouse door or roof job will be exposed, or whether the air handler can handle a better filter.
