Returning Home After a Fire FAQs

The following guidance is ONLY for properties that have suffered smoke damage AND do not have fire damaged structures, including yellow and red tagged structures. Pasadena Building Inspectors conducted Structure Safety Assessments for all structures within the wind and fire impacted areas, and colored placards were posted to each assessed property that corresponded to the structure’s safety status.

DO NOT ENTER your property if your property has been damaged directly by fire.

Note that this is general guidance and the City understands that every residence is different. Individuals should use their discretion and consider engaging professional help to make sure their property is suitable for return. If you have any doubts on the safety of your property, contact a professional for support and guidance. Licensed professionals can be found through the California Contractors State Licensing Board.

On 25 February, 2025, the U.S. Environmental Protection Agency (EPA) completed its Phase 1 hazardous materials removal mission. More information about this process can be found at the EPA 2025 Southern California Wildfire Response website.

What should people do if they return home and their house smells like smoke, but does not appear to be fire damaged?

Smoke is a combination of toxic air particles, including, fine particles, volatile organic compounds (VOCs), and many other reactive gases. Some of these compounds are toxic [e.g., dioxins, benzene, formaldehyde, polycyclic aromatic hydrocarbons (PAHs)]. What you smell are these toxic air particles settled on interior surfaces such as walls, furniture, curtains, etc. These odors will diminish over time.

Before re-entry, sniff for gas. If you detect natural or propane gas, or hear a hissing noise, leave the property immediately and call the fire department after you reach safety. If you have a propane tank system, turn off all valves and contact a propane supplier to check the system before use.

Protect your health

• Wear a well-fitted NIOSH approved respirator (such as an N95 or P100) when you clean up inside our home.
• Wear gloves, safety goggles, long-sleeved shirts, long pants, and shoes with socks to avoid contact with ash or debris. If you get ash on your skin, in your eyes, or in your mouth, wash it off as soon as you can.
• People with heart or lung disease (including asthma), older adults, and pregnant women should avoid cleanup activities as much as possible.
• Keep children and pets away from ash and cleanup activities.

Bring in fresh air

• Air out your indoor spaces as much as possible by opening windows and doors. If you have minimal smoke smell/damage inside your home – and the area outside smells worse – don’t take this step. Check the air quality in the Los Angeles Area on the South Coast AQMD website.

Check your Heating, Ventilation, and Air Conditioning (HVAC) or furnace

• Most systems have filters (the “blue wool” ones) that are not very effective for the smallest toxic air particles that can penetrate deepest into our lungs. Use MERV 11 or 12-rated filters and add 1” foam around the edges or tape over any gaps in the filter holder. These filters have a white cloth-like material and are pleated for a larger surface area to capture particles and to prevent a significant pressure drop. Change your furnace or HVAC filter monthly until the smell goes away.
• Clean your HVAC ducts. The evidence is limited on how this impacts general indoor air quality, but many ducts are poorly sealed, poorly maintained, and have poor filtration so can get contaminated.

Use air cleaners to help remove particles and odors

• Consider purchasing portable air cleaners with both a HEPA filter and activated carbon filter. The carbon filter is important as it will remove toxic air particles. The HEPA filter will remove 99.97% of the toxic air particles that penetrate deepest into our lungs. Keep air cleaners on until the smells go away and change the filters according to the manufacturer’s instructions.
• You may need to change the carbon filters more frequently since they get used up.
• You may want to change out the cabin air filter in your car if it was exposed to smoke and smells.

Deep clean the surfaces of your home

• Soap and water are adequate to clean ash from hard surfaces, including walls. Do not use harsh chemical cleaners or vinegar as they can react with chemicals in the ash.
• Gentle sweeping of indoor surfaces, followed by wet mopping, is the best way to clean indoors.
• Do not use shop vacuums or regular household vacuums as these do not filter small particles and can blow particles into the air. If available, HEPA-filter vacuums can filter out small particles and can be used.
• Commercial cleaning may be needed for carpet, upholstery, and window treatments.
• Shower regularly throughout the day when cleaning areas with ash.

What should people do to remove ash and debris from their property?

When cleaning up after a wildfire, it’s important to take safety precautions to protect yourself and your property. Ash can be irritating to the skin, eyes, nose, and throat. Ash may make it difficult to breathe and can aggravate asthma.

If you choose to consult a professional to conduct ash and debris removal, make sure they are licensed through the California Contractors State Licensing Board.

If you choose to conduct ash and debris removal of your own property:

Protect your health

• Wear a well-fitted NIOSH-approved respirator (such as an N95 or P100) when you clean up inside your home.
• Wear gloves, safety goggles, long-sleeved shirts, long pants, and shoes with socks to avoid contact with ash or debris. If you get ash on your skin, in your eyes, or in your mouth, wash it off as soon as you can.
• Shower regularly throughout the day when cleaning areas with ash.
• People with heart or lung disease (including asthma), older adults, and pregnant women should avoid cleanup activities as much as possible.
• Keep children and pets away from ash and cleanup activities.

Clean up ash and debris

• Do not use leaf blowers or take other actions that will put ash into the air.
• Avoid dry sweeping. Before sweeping ash off surfaces, wet down ash with as little water as you can. Continue to use caution while cleaning the wet ash, as contact with wet ash can cause chemical burns or skin irritation. On surfaces with a lot of ash, mist ash with water to keep dust down, then sweep. Wet mop the area after sweeping. On areas lightly dusted with ash, use a damp cloth or wet mop.
• Do not allow water to go down the driveway, down the street, or into storm drains. You may allow water to drain into landscaping as ash will not hurt plants or grass.
• If washing your roof, redirect downspouts to landscaped areas.
• Take your vehicle to a car wash or wash it over a vegetated area such as your lawn.
• Remove shoes before entering your home or use “sticky mats” in entryways and doors to remove dust and ash from your shoes. Sticky mats are sold in hardware stores.
• Collected ash may be disposed of in the regular trash by placing it in a plastic trash bag first to prevent the ash from becoming airborne and blowing away as the trash can is later emptied.
  • If you think any waste is hazardous (including asbestos), contact your local hazardous waste authorities regarding appropriate disposal.

Do I need to wear a mask outside if I am not cleaning or if air quality is “good”?

It is okay to go outside without a mask. Use your discretion and follow local guidelines. If you are cleaning or sweeping, if there are strong winds, or if your neighborhood is conducting debris removal, it is recommended you wear a well-fitted NIOSH-approved respirator (such as an N95 or P100). Check the air quality in the Los Angeles Area on the South Coast AQMD website.

What should I do about wildlife near my home after the fire?

Wildlife displaced by wildfire activity may enter your property or home. Places where there is an accumulation of trash or debris can attract wild animals.

• Keep garbage in rodent-proof containers that are tightly covered to avoid attracting animals.
• Do not leave pet food outdoors. Check for areas where rats and wild animals can sleep, hide, or find food. If possible, seal these areas.
• Protect yourself by wearing gloves and a mask when cleaning these areas. Wash your hands when you’re finished.

Can I eat food left in my home before I evacuated?

• Food safety may be a problem if the power outage lasted for a long period of time.
• If you experience a power outage or find that your kitchen has ash, soot, dust, and other airborne particles, avoid foodborne illness by following these recommendations:
  • Any food or drink products with an off odor or signs of spoilage should be thrown away. Best practice is: “When in doubt, throw it out.”
  • Generally, food in the refrigerator is safe if the power was out for no more than 4 hours and the refrigerator and freezer doors were kept closed. Keeping the doors to the refrigerator and freezer closed helps maintain the coldest temperatures.
  • If a power outage lasts more than four hours or the refrigerator door was not kept shut, it is best to throw away perishable food items such as meat, dairy products, and eggs.
  • If food from your refrigerator or freezer has an off-flavor or odor when prepared, it should be discarded and not eaten.
  • Items that have thawed in the freezer should be thrown away. Do not refreeze thawed food. All other food items should be inspected to ensure safety.
  • Plastic bottles with liquid (such as water) that have been covered in ash should be thrown away. It is not enough to rinse off the bottle as these particles contaminate the caps, making them very difficult to decontaminate.
  • Food that has not been stored in waterproof or airtight containers and has been covered with ash should be thrown away. This includes products that have been stored in cardboard or other soft packaging. Food stored in sealed, previously unopened glass or metal cans or jars (such as baby food) should be safe for use. Clean before opening and transfer the contents to another container before eating.
  • Discard any raw foods stored outside the refrigerator, such as potatoes or fruit, as fumes could contaminate them.
  • Throw food away in trash bags and seal tightly before placing in the trash can. Double bagging is recommended to prevent fly breeding.

What are ways that I can help my child cope after a wildfire?

Children’s reactions to the wildfires and the aftermath are strongly influenced by how parents, teachers, and other caregivers cope during and after the events. Children often turn to these adults for information, comfort, and help. Below are ways to help your child cope and process their emotions:

Talk About Wildfires

Give your children basic information, without providing unnecessary, scary details:

• Create an open environment to share relevant and age-appropriate information. Very young children need to know how it will affect them. Older children will likely want more information.
• Be patient and answer questions with honesty. Be prepared to wait for children to be ready to talk. When they are ready, provide honest answers and information. Validate children’s feelings and concerns by assuring them that their feelings and concerns are important and appropriate.
• Limit details and prevent your child’s access to media coverage. Provide reassurance and share recovery efforts. Prepare for repeated questions.

Be Aware of Your Child’s Mental Health and How They Are Coping

Your child may feel sad, anxious, and frightened. Encourage and validate your child’s feelings by:

• Make Time to Talk:
  • Dedicate time to let your child talk about their feelings and share your own feelings with them. Provide accurate and simple responses to their questions, but do not overwhelm them with too many details. If your child is returning to school, back home, or a new setting; provide your child information about these changes. Reassure them that you are doing everything you can to make sure that they are safe.
• Maintain A Routine:
  • Your child’s schedule can make them feel calm and provide a sense of familiarity such as keeping a bedtime routine, reading with your child, and setting daily time for playing with your child.
• Monitor Changes in Behavior:
  • Your child may be experiencing grief or displaying a trauma response. If you’re concerned about your child’s health and well-being, seek help from a primary care provider or mental health professional.

Wildfire Safety and Tips

Pasadena Unified School District has taken measures to help ensure that it is safe for students and faculty to return to school. Take steps to reduce the risk of your child breathing in air pollutants and potential contaminants during and after a wildfire.

• Monitor the air quality in Los Angeles at AQMD.gov.
• If the air quality is bad, stay inside as much as possible or consider wearing a mask.
• If air quality is good, there is a low risk of toxins in the air, and it is safer to go outside.
• If you see ash, dust, or debris, do not let children touch or play with it.
• Have children wash hands often, especially when returning from spending time outside, such as at a playground or school.
