The document discusses HVAC systems and mold. It provides information on what causes mold, how to prevent mold growth, who may be responsible if an HVAC system causes mold, and legal issues related to mold litigation. It notes that determining responsibility requires examining project contracts and hiring HVAC and mold experts. Research on damp indoor spaces and their health effects is still developing, and there is no consensus on what constitutes problematic dampness or valid exposure assessment methods.

Unit VIII Scenario #3: Case Of The Sealed Room
The Situation: You are working as an environmental consultant and one of your largest clients has called requesting your services. Your client is interested in purchasing a large parcel of land that includes a former airplane manufacturing facility. In total there are 7 major buildings on this property with minor support buildings as well. Your task is to conduct a pre-purchase environmental audit of the property and provide your client with your recommendations.
You have done all your research and scoured all the records and you are now making one last walk-through of the property with the caretaker when you notice a door on the side of what is commonly referred to as the paint hanger. The door happens to have a large, fairly old padlock on it keeping it shut tight. At first you are told it is just a side entrance to the main hanger floor, but based upon the contour of the building your better judgment does not agree.
You ask for the key to the lock and are immediately told that no one has the key. So, you get the bolt cutters and open the door. You are immediately greeted with an over-whelming vapor cloud that has the distinct scent of some form of a petroleum product. After you let the room air out, you discover a cache of ten 55-gallon drums (unlabeled), an old solvent bin with product still inside; an old tank approximately 100 gallon size labeled Used Oil, and a large assortment of 5-gallon buckets, all without labels.
What is your recommendation to your client?
The Questions:
1. If your client is set on purchasing this property what advice shall you provide?
2. If your client assumes the responsibility for clean-up and wants you to head the clean-up effort, what are some of your first steps?
Unit VIII Scenario #4: The Street Sweeper
The Situation: You are a newly hired Safety Analyst for a medium sized municipality in the southeast. One day your supervisor, the Risk Manager, asks you to speak with a street sweeper operator. Apparently the operator has been complaining of severe headaches and nausea for several days now and the doctors that he has been sent to cannot find anything wrong with him. The Risk Manager believes that this operator is a malingerer but wants you ...
What is mold? How does it start and what are the health effects? In this presentation you will learn all about mold and how it affected us when Hurricane Sandy struck.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

6. Why Do We Care Who Is
Responsible for the HVAC
System?
● If the architect of record, the
developer/property owner is responsible
for negligent HVAC design issues
● If the general contractor, the contractor
group is responsible (i.e., general, HVAC
designer, and HVAC installed)
● What Role Did Our Insured Play?
7. How Do We Know Who Is
Responsible for the HVAC
System?
● Look at the project contracts
● Who assumed responsibility for the HVAC
design?
● Architect?
● Builder?
● HVAC Installer?
● What kind of contracts?

8. How Do We Know Whether We
Have A Design Or Installation
Problem With the HVAC
System?
● Going to need HVAC experts;
● Design expert
● Installation expert
● Mold Investigator
● Forensic scientist; mold remediator re causation
issues
● Is Mold Problem Systemic Or Situational?
● Systemic probably design
● Situational probably installation issue
9. What Do We Want to Ask Our
HVAC Experts?
● Who assumed responsibility for the HVAC
Design in the Contracts and in Reality?
● What Was the HVAC Designer Designing
For?
● “Closed” Building
● Openable Windows?
● Hospital “Clean Room”?
● Did Installer Follow Design Or Design
Intent?
● Were Other Contractors Involved?
● Sloped Window Sills? Mold-Resistant Paint
10. What Do We Want to Ask Our
HVAC Experts?

Deaths Linked By U.S. Center for Disease
Control By Mold Exposure Alone
● http://www.cdc.
gov/ncezid/dfwed/mycotics/related_links.html
● http://www.cdc.gov/mold/links.htm
● http://www.igotmold.net/toxic-black-mold-
symptoms/
● But “Eggshell Skull” Plaintiffs at Risk
● Cancer; HIV+; Organ Transplant Recipients
● Weakened Immune Systems
14. LEGAL ISSUES IN MOLD LITIGATION
● What caused the mold?
[Liability]
● Were injuries caused by mold
exposure? [Damages]
● Admissibility of expert opinion
testimony [Evidence]
● Statutes of limitation [“SOL”]
15. STATUTES OF LIMITATION
● A review of the Statute of Limitations indicates that
the statute that applies depends on the nature of the
injury.
● FINANCIAL INJURY:
● 2 years
● Code of Civil Procedure § 339(1) applies to financial injury for
mold claims.
● INJURY TO OR LOSS OF REAL PROPERTY OR
TANGIBLE PERSONAL PROPERTY:
● 3 years
● Code of Civil Procedure § 338(b) is applicable.
● INJURIES TO PERSONS:
● 2 years
● Code of Civil Procedure § 335.1 is applicable.
16. STATUTE OF LIMITATIONS –
TOXIC TORT CASES
● A Special Limitations Statute, which
incorporates common law “discovery rule”
applies to toxic tort cases under California
Code of Civil Procedure § 340.8.
● This statue applies to ALL civil actions for
injuries from exposure to a “hazardous
material or toxic substance.”
● Its application to mold cases is uncertain,
17. STATUTE OF LIMITATIONS
PERSONAL INJURY – CONSTRUCTION DEFECT LITIGATION
● Deadline for Patent Defect is 4 years after the
improvement is substantially completed (if action is
against persons involved in the improvement, i.e.
designers, planners, contractors, etc. (Cal. Code of Civil
Procedure § 337.1(a)).
● If injury occurs in fourth year after improvement is
substantially completed, the action must be brought
within 1 year after date of injury, irrespective of date of
death, and not more than 5 years after improvement is
substantially completed. (Cal. Code of Civil Procedure §
337.1(b)).
● “Patent” means a deficiency which is apparent by
reasonable inspection (Cal. Code of Civil Procedure §
337.1(e))
● Caveat: statute does not apply to owner-occupied single
unit residences. (Cal. Code of Civil Procedure § 337.1(f))
18. STATUTE OF LIMITATIONS –
LATENT DEFECTS
● Actions for latent defects in the
development/improvement of real property must be
filed:
● Within 3 years of discovery for negligence;
● Within 4 years of discovery for breach of
contract/warranty; and,
● Within 10 years of the date of substantial completion
for ALL OTHER CLAIMS (Code of Civil Procedure, §
337.15(a)).
● California courts have NOT held that these Statutes of
Limitation apply to personal injury claims.
● Generally, for personal injury claims, the deadline is 2
years (Code of Civil Procedure, § 335.1) from the date of
the incident or injury.
20. Expert’s Role in Mold Cases
● Success Depends On The
Admissibility And Credibility Of
Experts
● Experts include industrial hygienists,
mycologists, toxicologists,
aerobiologists, microbiologists,
analytical microscopists,
neuropsychologists, immunologists,
M.D.s, and construction experts
21. Admissibility of Expert Testimony
● Split In Federal and State Courts
● Federal Courts (And Many States)
Follow U.S. Supreme Court’s
Daubert Decision
● Others, Like California, Follow
The “Kelly-Frye” Rule
22. Daubert And Its Progeny
● All Federal And Some State Courts
Admit Expert Opinion Testimony “Only
If” The Expert’s Opinion Is “Reliable.”
● Focuses On The Scientific Method
● Is The Expert’s Theory Provable/Proven?
● Were Proper Procedures Followed?
● Was The Theory Reviewed By Other
Credible Experts?
● Acceptable Margin of Error?
● Is The Theory Accepted By An Acceptable
Number of Other Experts?
23. California’s Kelly-Frye Rule
● Is “Scientific” Evidence At Issue?
(People v. Ward—California
Supreme Court holds rule does
not apply to psychiatry)
● Is The Expert’s Theory Generally
Accepted By The Scientific
Community?
● Is The Expert’s Theory “Novel”?
24. California’s Kelly-Frye Rule
● More Liberally Admits Expert
Opinion Testimony—Except For
“Novel” AND Scientific Evidence
● If Expert’s theory involves
“Science” and is “Novel,” THEN
Offering Party Must Show
Theory is “Generally Accepted”
By the Relevant Scientific
Community for Expert’s Opinion
to be Admitted
25. Where Kelly-Frye Bars Experts
● “Voice-Print” Identification—
California Supreme Court holds
identification device not generally
accepted by a recognized body of
scientists (People v. Kelly)
● Lie Detectors (Frye, federal case
holding not generally accepted)
● Truth Serums (Ramona v. Superior
Court, California Appellate Court
finds not generally accepted as
26. Kelly-Frye’s Application to Mold
Litigation
● Is the theory regarding the cause of
the mold “novel” and “scientific”?
● Is the theory that the mold caused
plaintiff’s harm “novel” and
“scientific”?
● Ordinarily DOES NOT APPLY to
Medical and Psychological Experts
(Wilson v. Phillips (1999))
27. Issues Related to Kelly-Frye: The
“Cottle” Motion
● Cottle v. Superior Court (1992) 3
Cal. App. 4th 1367, appellate court
approves requirement that plaintiff
must make prima facie case that
defendant caused plaintiff’s injuries
● Facts: 175 homeowners and renters
sued a developer for personal
injuries allegedly sustained from
exposure to toxic waste
28. More on Cottle
Trial Court Required Each Plaintiff To
Identify:
● The injury-causing chemical or toxic
substance;
● Dates, manner & place of exposure;
● Nature of injuries;
● Each medical expert who supported
each plaintiff’s injury claim
29. The Cottle Motion
● Each Cottle plaintiff who failed to
identify one or more of the items
required by the trial court had his
or her claim DISMISSED
● RESULT: Defendants now bring
Cottle motions before trial to
require plaintiffs to make a prima
facie case on liability and damage
● LIMITS: May not work outside
complex, multi-party cases
30. Other Limits On Cottle Motions
● Cannot require plaintiffs to submit
expert declarations
● Cannot avoid requirement that
defendants bring summary judgment
or other dispositive motion
● BUT: Trial court can order plaintiff to
state facts supporting claims
(Hernandez v. Superior Court
(2003))
31. How Do Juries React To Mold Claims?
● Jury verdicts range from defense
verdicts to multi-million dollar
recoveries
● Why?
● Credibility of Claims
● Credibility of Experts
● Attorney Expertise (Or Lack
Thereof)
32. How Do We Evaluate Mold
Claims?
● Good Fact Investigation: How
bad does the mold look? How
sick are the plaintiffs? How much
property must be
destroyed/repaired to remediate
the mold? What are the most
likely causes of mold?
● Good Expert Evaluation: How
credible is the expert? How
qualified? Can expert
communicate/explain well?
33. Damp Indoor Spaces And Its Effect
On Health
● There is no generally accepted
definition of dampness or what
constitutes a dampness problem.
● There is no single cause of
excessive indoor dampness and
the primary risk factors for it
differ across climates, geographic
areas and building types.

34. Damp Indoor Spaces and Its
Effect on Health
● One consequence of indoor dampness is
new or enhanced growth of fungi (mold)
and other microbial agents.
● Mold spores are regularly found in
indoor air and on surfaces and materials
– no indoor space is free of them.
35. No Standard Definition of
“Dampness”
● How free of microbial contamination a
surface or building material must be to
eliminate problematic exposures of mold to
occupants is unknown. This is based in part
on the notion there is no single generally
accepted term defining dampness or damp
indoor spaces or moisture; or what
constitutes excessive moisture in buildings.
● Protocols still need to be developed to
characterize the nature, severity, and extent
of the dampness as it affects mold growth.
36. Research and Definitions Are
Incomplete
● Research is in the early stages of understanding
the microbial ecology of buildings
● the length between dampness,
● different building materials and
furnishings
● microbial growth, microbial
interactions, dampness-related
chemical emissions from building
materials, and
37. Exposure Assessment
● There is a general lack of knowledge regarding
the role of micro-organisms in the development
and exacerbation of diseases found in
occupants of damp indoor environments.
● lack of valid quantitative exposure-
assessment methods
● Poor knowledge of which specific microbial
agents may primarily account for the presumed
health affects.
● Very few biomarkers have been
identified.
● The validity of exposure not known.
● The entire process of exposure is
poorly understood.
38. Methods for Assessing Human
Exposure to Mold
● Present methods are poorly
developed and more research is
needed.
● Difficulty is related to the large number of
mold species
● Mold allergen content and toxic potential
vary among species.
● The best known method is still counting
cultured colonies, which is problematic
39. Toxic Effects Of Mold/Bacteria
Toxicological studies, which examine toxic
effects using animals or cellular models,
cannot be used, by themselves, to draw
conclusions about human health effects.
● Such studies have established that exposure
to microbial toxins can occur via inhalation
and dermal exposure and through ingestion
of contaminated food.
● The doses of such toxins required to cause
adverse health effects in humans have not
been determined.

40. Stachybotrys Chartarum, Toxic Mold?
● The effect of Stachybotrys on humans has not
been proven.
● biologically plausible, but not proven
● Research has found sufficient evidence of an
association between exposure to damp indoor
environments and some respiratory problems in
asthmatic persons
● Epidemiologic studies also show there is
sufficient evidence to conclude the presence of
mold indoors may be associated with upper
respiratory symptoms in susceptible persons.
● But EXCEPTION for Weak Immune Systems!
41. Limited Or Suggestive Evidence
● An association between
exposure to damp environments
and shortness of breathe, lower
respiratory illnesses, or
otherwise healthy children and
the development of asthma.
● It is not clear whether the later
association reflects exposure to
mold or bacteria.
42. Inadequate or Insufficient Information
● Insufficient information to
determine whether damp indoor
environments or agents associated
with them are related to a variety
of health issues, including Acute
Idiopathic Pulmonary
Hemorrhage In Infants (IHPHI).
● The CDC has been encouraged to
pursue surveillance and additional
research on this issue.
43. Difference between
Scientific and Legal Cause
● Scientific community: If X,
then Y 90% of the time, then X
“causes” Y
● Legal community: If X, then Y
50%+, then X “causes” Y—
“More Likely/Probable Than
Not Standard”
