WARNING: Ash from burned homes and other items will likely contain potentially toxic materials if breathed in or touched with wet skin, such as metals, chemicals, and potentially asbestos




RIVERSIDE COUNTY, CA — 

As the massive Holy Fire continues to grow, forcing thousands of Southwest Riverside County residents from their homes, another danger lurks: ash. Riverside County health officials issued a warning Thursday to area residents to "take precautions as they clean up the ash that has fallen on their cars, homes and driveways."

"Just because it's burned up doesn't make it safe," said Dr. Cameron Kaiser, Riverside County public health officer. "Ash can be toxic even in small quantities depending on where it came from."

And as eager as you may be to get that ash off your property, health officials urged residents to wait. They said "residents should not begin the clean-up while ash is still falling and the situation is unpredictable."

What's more, the county health department said to try your best to avoid skin contact with the ash.

"Ash from burned homes and other items will likely contain potentially toxic materials if breathed in or touched with wet skin, such as metals, chemicals, and potentially asbestos," the agency said. "If you do get ash on your skin, wash it off immediately. Some wet ash can cause chemical burns."

As inhaled ash "may be irritating to the nose, throat and lungs," health officials suggested the following:
  • Avoid activities that stir up ash.
  • Do not allow children to play in ash or be in an area where ash-covered materials are being disturbed.
  • Wash ash off toys before children play with them.
  • Clean ash off pets.
  • Clean-up of larger quantities of ash should never be done by people who have lung or heart conditions.
  • If you must clean up a larger quantity of ash, wear a tight-fitting respirator mask (such as an N95 or P100 mask found at hardware stores), gloves, long-sleeved shirts and long pants. The mask should cover your mouth and nose and seal properly.
  • Avoid sweeping up dry ash into the air.
  • Use water and wet cloth or mop to clean items and surfaces.
  • Sweep gently with a push broom, then hose lightly with water. Take care to conserve water. Ash can be bagged and put into trash cans.
  • Wet (or moisten) ash lightly with water (hose or spray bottle), then gently sweep with a push room. A shop vacuum equipped with a high-efficiency particulate filter (HEPA) and a disposable filter bag can also be used to pull up moistened ash.
  • Do not use leaf blowers, which can stir up ash and can contribute to large particles becoming smaller, more hazardous particles.
Here's more from the County of Riverside:

Larger ash particles can cause irritation to the eyes, nose and throat. Over time, ash particles break down into smaller, more harmful particles that can lodge deep into our lungs, causing serious health effects, including aggravated asthma, bronchitis, and lung damage. The particles are also small enough to get into our bloodstream and have other toxic effects.

If you have symptoms that may be related to exposure to smoke or soot, consult your doctor. Symptoms include repeated coughing, shortness of breath or difficulty breathing, wheezing, chest tightness or pain, palpitations, headaches and nausea or unusual fatigue or lightheadedness.

If your home was impacted by the Thomas fire, here are some health precautions to take after you return home and before you begin the clean-up process.
We do not advise ash clean-up while ash is still falling and the situation is unpredictable. Wait until conditions improve.
Avoid skin contact with ash. Ash from burned homes and other items will likely contain metals, chemicals, and potentially asbestos, items that may be considered toxic if breathed in or touched with wet skin. If you do get ash on your skin, wash it off immediately. Some wet ash can cause chemical burns.
Inhaled ash may be irritating to the nose, throat and lungs. In order to avoid possible health problems, the following steps are recommended.
  • Avoid doing activities that stir up ash. Do not allow children to play in ash or be in an area where ash-covered materials are being disturbed. Wash ash off toys before children play with them.
  • Clean ash off pets.
  • Wear a tight fitting N95 respirator mask, gloves, long-sleeved shirts and long pants when cleaning up ash.
  • Avoid getting ash into the air as much as possible. Avoid sweeping it up dry. Use water and wet cloth or mop to clean items and surfaces.
  • Under any circumstances, DO NOT USE LEAF BLOWERS!

If you have symptoms that may be related to exposure to smoke or soot, consult your doctor. Symptoms include repeated coughing, shortness of breath, or difficulty breathing, wheezing, chest tightness or pain, palpitations, headaches and nausea or unusual fatigue or lightheadedness.

When houses burn, asbestos fibers from building materials may become airborne, creating a potentially hazardous situation. Cleanup can make conditions worse if not done properly. Handling materials that contain asbestos can be hazardous to your health.
 
Note: Anyone with heart or lung problems should not do ash cleanup.
 
 For general ash cleanup:
  • Use damp cloths, spray areas lightly with water, and direct ash-filled water to ground areas, and away from the runoff system. Try to use the minimum amount of water necessary to avoid overtaxing runoff systems.
  • Use vacuums with HEPA filters, sweep gently with a broom.
  • Take your car to the car wash.
  • Wash off toys that have been outside in the ash; clean ash off pets.
  • Avoid any skin contact with the ash (wear gloves, long-sleeved shirts).
  • Use a high-quality shop/industrial vacuum outfitted with a high-efficiency particulate filter and a disposable collection filter bag. Ash can be bagged and put into trash cans, so it will not be stirred up again into the air. Special attachments can be used to clean ash from gutters, so that it will not blow back over outdoor spaces. Attachments and disposable bags are available from most hardware stores.

DON’T:
  • Allow kids to play in the ash.
  • Use leaf blowers! Click here to learn more about safe leaf blower use.
