Where there’s smoke, there’s a fight

As the Los Angeles wild­fires died out in Janu­ary, fire­fight­ers trekked through the burn zones to take stock of the destruc­tion. For every home they found leveled, they coun­ted another still stand­ing. The struc­tures looked fine from the out­side, but ash and oily soot often coated the floors and fur­niture, while invis­ible chem­ic­als bur­rowed into clothes, blankets and even walls.

Many of these smoke-soaked homes quickly became battle­grounds. On one side were cost-con­scious insur­ance com­pan­ies, who largely res­isted test­ing for heavy metals, order­ing the homes wiped clean and telling poli­cy­hold­ers it was fine to move back. On the other, sur­viv­ors of the Eaton and Pal­is­ades fires, fear­ful that the dan­ger­ous pol­lut­ants dust­ing their homes could one day make them sick.

While each side has its self-pro­claimed experts, no state or fed­eral stand­ards gov­ern this new fron­tier of urban mega-fires. Real­iz­ing this, the Cali­for­nia Depart­ment of Insur­ance formed a task force in May and gave it a crit­ical man­date: to write guidelines, groun­ded in sci­ence, that could influ­ence new state laws and insur­ance stand­ards for test­ing and clear­ing smoke con­tam­in­a­tion. The task force is sched­uled to deliver its recom­mend­a­tions to Insur­ance Com­mis­sioner Ricardo Lara early next year.

But a Chron­icle invest­ig­a­tion of the 13-mem­ber com­mit­tee, whose meet­ings are cur­rently closed to the pub­lic,

“Our dam­ages in Alt­adena from tox­icity are being com­pared to 9/11. The idea they’re put­ting together a task force to sup­port them put­ting us back in that space, it’s really just uncon­scion­able.” Libby God­win, Alt­adena res­id­ent strug­gling with a smoke-dam­age claim

found that it doesn’t have a single tox­ic­o­lo­gist or sci­entific expert in the chan­ging chem­istry of smoke from urban fires. Instead, its five tech­nical expert voices include three con­sult­ants who have spent years help­ing insurers dis­pute con­sumers’ smoke-dam­age claims and defend­ing the com­pan­ies when those poli­cy­hold­ers sue.

These three con­sult­ants have fought Los Angeles County fire sur­viv­ors’ inde­pend­ent test res­ults of con­tam­in­a­tion in their homes on behalf of at least half of Cali­for­nia’s biggest insur­ance com­pan­ies, redu­cing insurers’ poten­tial costs, the Chron­icle found. And they have done so using prac­tices that, while align­ing with cer­tain stand­ards in the envir­on­mental-test­ing industry, con­flict with aca­demic research.

Wild­fire sur­viv­ors and advoc­ates track­ing the task force’s activ­it­ies fear it will effect­ively write the home insur­ance industry’s play­book for min­im­iz­ing dam­age claims into Cali­for­nia law, with rami­fic­a­tions for homeown­ers’ pay­outs — and their abil­ity to recover from dis­aster — for dec­ades to come.

“I am very con­cerned about undue influ­ence,” said Amy Bach, one of two con­sumer advoc­ates on the task force and the exec­ut­ive dir­ector of the advocacy group United Poli­cy­hold­ers.

Bach said she had recom­men­ded what she con­sidered a bal­anced slate of experts to the task force, includ­ing pub­lic adjusters, plaintiffs’ attor­neys and con­sumer-focused hygien­ists, who test for con­tam­in­a­tion and recom­mend clean­ing pro­to­cols. Because the final com­pos­i­tion so leans toward insurers’ point of view, she said, “I do not believe this panel is in a pos­i­tion to issue recom­men­ded stand­ards.”

Deputy Insur­ance Com­mis­sioner Tony Cig­narale, who chairs the task force, told the Chron­icle that the state agency vet­ted each mem­ber, gauging their qual­i­fic­a­tions and how “open-minded” they seemed. He said he was aware that some mem­bers of the com­mit­tee primar­ily work for insur­ance com­pan­ies, but that the depart­ment bal­anced mem­ber­ship between industry and con­sumer voices.

“It would be inap­pro­pri­ate of us to just bring in all con­sumer-ori­ented hygien­ists, so to speak, and come up with (recom­mend­a­tions), then try and shove it down the insur­ance com­pan­ies’ throat,” he said.

The depart­ment, however, did not ask can­did­ates for the task force to dis­close the extent of their fin­an­cial ties to insurers. The Chron­icle found that com­pan­ies asso­ci­ated with three mem­bers — Brad Kovar, Hamid Arabz­a­deh and Michelle Ros­ales — primar­ily advert­ise their ser­vices to insur­ance com­pan­ies online, are on insur­ance com­pan­ies’ internal lists of go-to experts, and write reports on behalf of insur­ance com­pan­ies that chal­lenge test­ers brought in by homeown­ers.

Qual­i­fic­a­tions

The other two tech­nical experts on the com­mit­tee come from com­pan­ies that work for both insurers and homeown­ers. The task force is roun­ded out by two insur­ance industry lob­by­ists; two con­sumer advoc­ates, includ­ing Bach; a pair of pub­lic health offi­cials and a deputy dir­ector for Cal Fire, the state’s fire response agency.

Kovar is the CEO of test­ing com­pany Safe­guard EnviroGroup and a co-owner of legal con­sult­ing firm Envir­oLegal. He and his com­pan­ies have writ­ten reports cri­ti­ciz­ing Los Angeles homeown­ers’ test­ing res­ults on behalf of State Farm Gen­eral Insur­ance Co.; Farm­ers Insur­ance Group; the Cali­for­nia FAIR Plan; and the Inter­insur­ance Exchange of the Auto­mobile Club, the AAA-affil­i­ated insurer for South­ern Cali­for­nia.

While Kovar said his com­pan­ies’ ser­vices “are avail­able to all parties and entit­ies who request” them, an insur­ance depart­ment spokes­per­son said Kovar was selec­ted “with the know­ledge that his primary busi­ness interests were with the insur­ance industry.”

Arabz­a­deh, the head of HRA Envir­on­mental Con­sult­ants, told the Chron­icle he believes that prac­tic­ally every type of con­tam­in­a­tion from wild­fire smoke inside a dwell­ing can be vacu­umed or wiped clean, a view sup­por­ted by some industry­sponsored envir­on­mental test­ing research but dis­puted by inde­pend­ent sci­ent­ists.

Ros­ales is the dir­ector of envir­on­mental health ser­vices for Forensic Ana­lyt­ical Con­sult­ing Ser­vices, or FACS, which has worked closely with insurers includ­ing State Farm to inspect wild­fire con­tam­in­a­tion for more than a dec­ade, records show.

The Chron­icle examined hun­dreds of pages of reports writ­ten by Kovar, Arabz­a­deh and Ros­ales on behalf of insurers, and found that they routinely failed to describe the poten­tial health risks posed by harm­ful chem­ic­als found in sur­viv­ors’ homes while attrib­ut­ing some con­tam­in­a­tion to candles and unused fire­places rather than the wild­fires.

The three mem­bers often advoc­ate for primar­ily using sight and smell to invest­ig­ate smoke dam­age to a home, and Kovar and Arabz­a­deh have claimed that more rig­or­ous chem­ical test­ing can be unne­ces­sary or mis­lead­ing, even though many chem­ic­als being found in South­ern Cali­for­nia homes are so toxic they can sicken people, espe­cially chil­dren, at levels in which they are invis­ible and odor­less.

The decon­tam­in­a­tion meth­ods these mem­bers recom­mend — often high­powered vacu­um­ing and clean­ing alone — are increas­ingly being chal­lenged by new stud­ies. As major fires become more urban and toxic, the stud­ies show, sur­viv­ors with smoke-rid­den dwell­ings might have to replace walls and throw out fur­nish­ings and other items to truly make their homes safe.

Kovar, in a lengthy writ­ten response to ques­tions, denied that insur­ance com­pan­ies com­prised the major­ity of his com­pany’s cus­tom­ers, say­ing he has per­formed tests for more than 140 non-insurer cli­ents in Los Angeles. He said his pro­to­cols are up to par with industry stand­ards, cit­ing a guide­book he co-authored.

‘Scar­ing people’

“Con­cerns about poten­tial bias are under­stand­able,” he wrote. “What I can say with con­fid­ence is that my involve­ment on this Task Force is groun­ded in the same prin­ciple that has guided my entire pro­fes­sional career: a com­mit­ment to object­ive, evid­ence-based prac­tice.”

In a writ­ten state­ment, Ros­ales said her com­pany per­formed post-wild­fire test­ing for a range of cli­ents, includ­ing homeown­ers, insur­ance com­pan­ies and schools. While it’s true that “most wild­fire dam­age assess­ments … by FACS or oth­ers, are at the request of insur­ance com­pan­ies,” she said, this alone did not bias her reports.

“The fact that an insur­ance com­pany or any other cli­ent may pay for our ser­vices has no bear­ing on our con­clu­sions or recom­mend­a­tions,” she wrote.

Arabz­a­deh said in an inter­view that he had tested between 40 to 60 homes after the Los Angeles wild­fires, the major­ity for insur­ance com­pan­ies and the rest pro bono for homeown­ers. He said he believes the sci­ence around test­ing and clean­ing homes is estab­lished and that cur­rent meth­ods such as vacu­um­ing and wet wip­ing are usu­ally suf­fi­cient. He cri­ti­cized some hygien­ists for con­duct­ing what he called “irrel­ev­ant” test­ing for vast arrays of chem­ic­als, then need­lessly dram­at­iz­ing their find­ings as evid­ence of irre­vers­ible con­tam­in­a­tion.

“They’re scar­ing people,” he said, adding, “We do not live in a sterile world.”

To under­stand the battle over smoke dam­age play­ing out in Los Angeles and its sci­entific under­pin­nings, report­ers inter­viewed 20 experts, includ­ing indus­trial hygien­ists, remedi­ation con­tract­ors and research­ers who study wild­fire con­tam­in­a­tion. They also spoke to more than a dozen industry rep­res­ent­at­ives and homeowner advoc­ates.

Test­ing com­pan­ies have found alarm­ing levels of

heavy metals and car­ci­no­gens inside of hun­dreds of sur­viv­ors’ homes, includ­ing lead, a known com­pon­ent of wild­fire smoke that can cause birth defects and harm chil­dren’s brain devel­op­ment. The Envir­on­mental Pro­tec­tion Agency and the Cen­ters for Dis­ease Con­trol and Pre­ven­tion advise there is no safe level of lead in a child’s blood. Test­ing has also detec­ted poten­tially dan­ger­ous levels of asbes­tos, beryl­lium and arsenic dus­ted across kit­chens and chil­dren’s bed­rooms within the burn zone.

Karen Collins, one of two insur­ance industry advoc­ates on the task force, said insurers are com­mit­ted to estab­lish­ing sci­ence-backed stand­ards for how to remedi­ate such con­tam­in­ants. Without stand­ards, insurers too are left vul­ner­able — to super­flu­ous lit­ig­a­tion and oppor­tun­istic con­tract­ors, she said.

Collins, a vice pres­id­ent at the Amer­ican Prop­erty and Cas­u­alty Insur­ance Asso­ci­ation, poin­ted to a recent train­ing that offered to teach con­tract­ors the “excit­ing oppor­tun­ity” of smoke-dam­age claims, tout­ing its high poten­tial profit mar­gins.

But the homeown­ers inter­viewed by the Chron­icle said they’re not try­ing to squeeze their insurers. They just don’t want to move back into build­ings that could slowly poison their fam­il­ies.

“Our dam­ages in Alt­adena from tox­icity are being com­pared to 9/11,” said Libby God­win, an Alt­adena res­id­ent strug­gling with a smoke-dam­age claim. “The idea they’re put­ting together a task force to sup­port them put­ting us back in that space, it’s really just uncon­scion­able.”

The show­down

When the Depart­ment of Insur­ance announced the form­a­tion of the Smoke Claims & Remedi­ation Task Force in May, many sur­viv­ors of the Los Angeles fires expressed cau­tious optim­ism. Hun­dreds had battled their insur­ance com­pan­ies for months to cover even the most basic tests.

One Alt­adena res­id­ent, Karen Gir­ard, returned home after the fires to find dark ash speck­ling her white cloth­ing and piled up at the foot of her bed. Sealed jars of marsh­mal­lows and white chocol­ate chips in her kit­chen cab­in­ets had turned brown.

Fore­most Insur­ance Group — a sub­si­di­ary of Farm­ers, the second largest home insurer in Cali­for­nia — told Gir­ard the home just needed to be cleaned. She asked her insurer to pay for an indus­trial hygien­ist to sample the debris and determ­ine whether it con­tained chem­ic­als that could endanger her health. Fore­most said no — until the county warned res­id­ents liv­ing near the burn zone could be exposed to lead and asbes­tos.

At that point, the insurer tapped its own vendor to come to her home. Their sampling found lead at a level sev­eral times higher than fed­eral safety stand­ards, as well as arsenic. When the vendor recom­men­ded pro­fes­sion­als only clean the areas of the floor around her win­dows, Gir­ard sought a second opin­ion.

Gir­ard’s tester, M.A.R.S. Envir­on­mental, found lead, arsenic, chro­mium and nickel. It recom­men­ded going bey­ond rig­or­ous clean­ing by at a min­imum repla­cing dry­wall and insu­la­tion. Her insurer fired back again — this time, by hir­ing Kovar’s legal firm, Envir­oLegal. His firm wrote a report that argued the deeper test res­ults were “unre­li­able.” Fore­most then refused to reim­burse Gir­ard for M.A.R.S.’ test­ing costs and pushed back on its recom­mend­a­tions.

“It became a show­down,” she said. “They weren’t remotely inter­ested in keep­ing me safe.”

Stor­ies like Gir­ard’s have played out repeatedly across the Eaton and Pal­is­ades fires’ burn zones.

The Chron­icle reviewed three dozen reports authored by mem­bers of the task force or employ­ees of their com­pan­ies for homes in Alt­adena or the Pacific Pal­is­ades neigh­bor­hood. Some were ori­ginal test res­ults and recom­mend­a­tions, while oth­ers were cri­tiques of work done by other experts. Report­ers also inter­viewed more than three dozen sur­viv­ors with smoke­dam­aged homes.

Nearly all described sim­ilar exper­i­ences: After insur­ance com­pan­ies declined to cover test­ing for con­tam­in­ants in their homes, they paid for it them­selves. It was only then, they said, that their insurers hired experts of their own, who were often mem­bers of the task force or the com­pan­ies that employ them.

Nine­teen of the reports the Chron­icle reviewed didn’t involve any new test­ing. Instead, Kovar, Arabz­a­deh and their com­pan­ies wrote “rebut­tal reports” to refute out­side test­ers’ con­clu­sions. Many of the reports authored by Kovar and his asso­ciates con­tained identical lan­guage that appeared to have been copied and pas­ted.

When they per­formed their own tests, the com­mit­tee mem­bers’ meth­ods were typ­ic­ally less com­pre­hens­ive than those used by the test­ers hired by homeown­ers, the Chron­icle found. For instance, Kovar’s Safe­guard EnviroGroup routinely used a cheaper and less sens­it­ive method to test for asbes­tos — which Kovar said was the “stand­ard method for identi­fy­ing asbes­tos-con­tain­ing build­ing mater­i­als in debris.”

In one case the Chron­icle reviewed, the test failed to find asbes­tos in a home before a more sens­it­ive test paid for by the homeowner picked up the min­eral, which can cause the deadly can­cer meso­the­lioma.

“They’re com­ing in already as an adversary,” said Debbie McMa­hon, a AAA poli­cy­holder.

Recom­mend­a­tions

McMa­hon’s ash-filled Alt­adena home is a time cap­sule of the days just before the fire, her Christ­mas tree still pitched in the liv­ing room. She said Safe­guard tech­ni­cians vis­ited the house in late Septem­ber, wear­ing almost no pro­tect­ive equip­ment and using a com­pany busi­ness card to scoop up a pile of ash. They balked when the tester she’d hired ques­tioned their meth­ods. McMa­hon was so rattled, she said, that she obtained her own lead sampling cer­ti­fic­a­tion.

In reports the Chron­icle reviewed, the mem­bers’ firms’ recom­mend­a­tions for clean­ing and res­tor­a­tion were con­sist­ently less extens­ive than what com­pan­ies hired by homeown­ers sug­ges­ted.

In at least six cases, samples taken by Kovar’s firms went to Liberty Envir­o­Lab, a labor­at­ory com­pany with loc­a­tions in the South­ern Cali­for­nia cit­ies of San Mar­cos and Cer­ri­tos, for ana­lysis. On LinkedIn, Kovar sug­ges­ted Liberty was the “new gold stand­ard” of test­ing and said Safe­guard was “send­ing a lot of busi­ness” its way.

State records show the firm was ori­gin­ally registered at a single-fam­ily home in Temec­ula — the same home Kovar lis­ted as his mail­ing address for his two other com­pan­ies, Envir­oLegal and Safe­guard. Kovar did not men­tion the ties in either his formal reports reviewed by the Chron­icle or his social media posts. He told the Chron­icle that he provided “ini­tial fin­an­cing” for the lab, but that he plays no role in dir­ect­ing its cur­rent oper­a­tions.

Safe­guard did, however, pro­mote Kovar’s role on the task force on Ins­tagram. “Trust the experts who helped define the rules,” read the post. “Book your inspec­tion today.”

All mem­bers of the task force, includ­ing Kovar, signed an agree­ment with the Depart­ment of Insur­ance prom­ising not to use their pos­i­tions for “private gain or advant­age,” accord­ing to Cig­narale.

Asked about the Ins­tagram post, Kovar said it was a “fac­tual dis­clos­ure” that “high­lighted our tech­nical expert­ise and par­ti­cip­a­tion in stand­ards devel­op­ment,” but was not inten­ded for private gain. A spokes­per­son for the Depart­ment of Insur­ance said the depart­ment did not feel the post viol­ated its stand­ards, but asked Kovar to delete it after the Chron­icle’s inquiry.

Down the ‘rab­bit hole’

New research is show­ing that smoke from the urban infernos in Los Angeles — car­ry­ing charred bits of cen­tury-old houses and brand-new elec­tric cars, paint fumes and particles from lith­ium bat­ter­ies — is far more dan­ger­ous than what wild­fires his­tor­ic­ally car­ried.

Michael Jer­rett, a UCLA envir­on­mental health pro­fessor, is part of a coali­tion of sci­ent­ists known as the L.A. Fire Human Expos­ure and Long-Term Health Study that has been invest­ig­at­ing how emis­sions from the his­toric blazes impact pub­lic health. Jer­rett has been study­ing the air qual­ity inside homes since the second day of the fires.

His team has found that homes held on to high levels of toxic com­pounds for weeks or even months after the flames sub­sided because couch cush­ions and por­ous dry­wall soak in the chem­ic­als and then release them into the air over time.

“Nobody should be going back and liv­ing in this toxic soup” without thor­ough decon­tam­in­a­tion of the struc­ture and belong­ings, Jer­rett said.

Joe Nieusma, a vet­eran Col­or­ado tox­ic­o­lo­gist, said that any state craft­ing wild­fire smoke insur­ance guidelines needs to factor in recent research on the shift­ing char­ac­ter­ist­ics of smoke con­tam­in­a­tion. In a study pub­lished this year, Nieusma found that micro­scopic smoke particles — with dia­met­ers one-hun­dred­fold smal­ler than a human hair — embed in HVAC sys­tems and a home’s tini­est crevices. Even the most heavy-duty vacu­ums can­not cap­ture them all, and a home’s nat­ural air­flow will even­tu­ally recir­cu­late them.

Jer­rett’s col­league on the L.A. Fire HEALTH Study, UCLA envir­on­mental health pro­fessor Yifang Zhu, is study­ing whether house­hold wash­ing machines effect­ively clean wild­fire-con­tam­in­ated cloth­ing. While her research remains pre­lim­in­ary, one exper­i­ment found that even three cycles of wash­ing and dry­ing did not rid a piece of fab­ric of wild­fire con­tam­in­ants known as volat­ile organic com­pounds — gas pol­lut­ants spread by fires that can embed into por­ous items, walls and sur­faces. She’s col­lec­ted more samples to fur­ther test the find­ing.

An August pilot study by fed­eral sci­ent­ists found

that wash­ing lead-con­tam­in­ated cloth­ing in res­id­en­tial wash­ing machines did not com­pletely remove the heavy metal. Worse, the sci­ent­ists found that some of the lead lingered in the machine and spread to pre­vi­ously uncon­tam­in­ated loads of laun­dry. Other metal particles such as beryl­lium spread sim­il­arly, experts said, and even­tu­ally can absorb into people’s skin.

Des­pite this, Kovar, Ros­ales or people work­ing for their com­pan­ies recom­men­ded machine­wash­ing to cleanse con­tam­in­ated cloth­ing and bed­ding in nine reports reviewed by the Chron­icle.

Across five reports, Kovar’s Safe­guard and Ros­ales’ FACS provided the same advice word for word: “Wash­able fab­rics, includ­ing cloth­ing, lin­ens, small rugs, and other soft items can gen­er­ally be machine-washed twice with hot water and deter­gent. Dry-clean­ing is also gen­er­ally accept­able.”

In another two reports, Kovar’s firm Envir­oLegal recom­men­ded “hand or high-tem­per­at­ure machine wash­ing and deep clean­ing,” adding, “If the mater­ial is heav­ily soiled or made from del­ic­ate fab­rics, con­sult a pro­fes­sional clean­ing ser­vice.”

Des­pite the reports’ word­ing, Kovar told the Chron­icle his com­pany “never recom­mends that homeown­ers wash lead­con­tam­in­ated cloth­ing in their own machines.” He added that he includes lan­guage at the top of every report say­ing his clean­ing recom­mend­a­tions should be under­taken by pro­fes­sion­als “in com­pli­ance with all local and fed­eral reg­u­la­tions.” Ros­ales said her com­pany recom­mends pro­fes­sional clean­ing of items “when lead remedi­ation is indic­ated.”

Even pro­fes­sional clean­ings by remedi­ation com­pan­ies can fail to cleanse liv­ing spaces, experts told the Chron­icle.

Eaton Fire Res­id­ents United, a coali­tion of fire sur­viv­ors, obtained lab res­ults from 50 homes that had tested pos­it­ive for harm­ful sub­stances, such as lead and mer­cury.

Of those, 45 homes ini­tially tested pos­it­ive for lead and under­went clean­ing, most through meth­ods approved by insurers.

All but two of them still con­tained levels above EPA stand­ards when retested. Out of 25 homes cleaned to remove asbes­tos, nine still tested pos­it­ive for the car­ci­no­gen after remedi­ation.

Post-cleanup test­ing is “abso­lutely cru­cial,” Nieusma said. But while task force mem­bers’ reports often recom­men­ded at least some post-cleanup test­ing, the Chron­icle found some insur­ance com­pan­ies reg­u­larly denied cov­er­age for such tests.

Chem­ical know­ledge

Know­ledge of chem­ic­als like these — and where they show up in homes — is crit­ical to under­stand­ing the health haz­ards from fires that encroach into res­id­en­tial areas, said François Tis­sot, a geo­chem­istry pro­fessor at the Cali­for­nia Insti­tute of Tech­no­logy who is study­ing the heavy metals and lead depos­ited in peoples’ homes by the Eaton Fire.

“You’re burn­ing houses and indus­trial mater­i­als and con­struc­tion mater­i­als,” he said. “The tests and clean­ing pro­to­cols which have been tested for wild­fires might not apply to an urban firestorm.”

Yet in inter­views and mater­i­als reviewed by the Chron­icle, insurer­aligned task force mem­bers took the oppos­ite view. They’ve argued that the rudi­ment­ary tests they’ve been using to assess smoke dam­age for years are suf­fi­cient for Los Angeles fire sur­viv­ors, dis­miss­ing more thor­ough chem­ical test­ing as unne­ces­sary and even a waste of poli­cy­hold­ers’ money.

As a mem­ber of the task force, Kovar invited mem­bers of a hygien­ist industry group to give the com­mit­tee a present­a­tion, which said com­pre­hens­ive test­ing for toxic sub­stances can be an “unne­ces­sary rab­bit hole.”

The presenters, along with Kovar, are co-authors of a tech­nical guide book that lays out instruc­tions for eval­u­at­ing homes after wild­fires. The guide was co-authored by 17 test­ing and remedi­ation pro­fes­sion­als. However, crit­ics argue its recom­mend­a­tions — which place a heavy emphasis on the use of sight and smell dur­ing invest­ig­a­tions — have not kept pace with research reveal­ing the tox­icity of urban fire smoke, and the stub­born per­sist­ence of poten­tially harm­ful but invis­ible and odor­less chem­ic­als inside affected dwell­ings.

Kovar said the term “rab­bit hole” referred to the “mis­use of com­plex ana­lyt­ical data” by some test­ing com­pan­ies which wrongly claim homes need “to be torn down based on the mere detec­tion” of chem­ic­als from wild­fire smoke.

Cig­narale noted that the task force was also soli­cit­ing present­a­tions from a “diverse” array of stake­hold­ers, includ­ing other hygien­ists and legal experts. A spokes­per­son for the depart­ment added that the panel has taken “extens­ive pub­lic input” via present­a­tions from out­side groups, such as Eaton Fire Res­id­ents United and Whelton, the Purdue sci­ent­ist.

In an inter­view in early Novem­ber, Arabz­a­deh ini­tially told the Chron­icle that test­ing is not always neces­sary if char and ash are vis­ible inside a home, because clean­ing pro­to­cols will be the same regard­less of what is found.

“That money would bet­ter be spent on get­ting remedi­ated,” he said.

Nieusma told the Chron­icle this is inac­cur­ate, as par­tic­u­lar chem­ic­als require spe­cial­ized and at times intens­ive clean­ing meth­ods. In cases of asbes­tos con­tam­in­a­tion, experts strongly recom­mend that gov­ern­ment-cer­ti­fied asbes­tos con­sult­ants eval­u­ate risks and guide cleanup efforts. Con­tract­ors remov­ing lead are required to have state cer­ti­fic­a­tions and use spe­cial solvents.

Asked about these require­ments on a fol­low-up call sev­eral weeks later, Arabz­a­deh back­tracked, say­ing he believed that test­ing should be done any­time there’s a reason to sus­pect asbes­tos and lead con­tam­in­a­tion, which he defined as the home hav­ing vis­ible debris.

Asbes­tos is odor­less. Lead dust doesn’t have a dis­tinct scent, either. Lab ana­lysis has con­firmed the wide­spread pres­ence of both in the burn zones — par­tic­u­larly in Alt­adena, where most of the homes that burned were built before the harms of asbes­tos-laden insu­la­tion and lead paint were widely recog­nized.
