Pursuant to the Maryland Uniform Certification of Questions of Law Act, Maryland Code (1974, 2002 RephVol., 2005 Cum.Supp.), Courts and Judicial Proceedings Article, §§ 12-601 though 12-613, and Maryland Rule 8-305, the United States District Court for the District of Maryland (Garbis, J.) certified the following question for our consideration:
*452 Whether an insurance company has a duty to defend and/or indemnify its insured in underlying actions alleging injury from exposure to localized welding fumes
a) Where the insurance policy contains a total pollution exclusion that denies coverage for “ ‘bodily injur/ or ‘property damage’ which would not have occurred in whole or part but for the actual, alleged or threatened discharge, dispersal, seepage, migration, release, or escape of pollutants at any time,”
b) Where pollutants are defined as “any solid, liquid, gaseous, or thermal irritant or contaminant including smoke, vapor, soot, fumes, acids, alkalis, chemicals and waste,” and
c) Where waste is defined as “materials to be recycled, reconditioned or reclaimed.”
We respond in the affirmative to the certified question.
I.
The District Court supplied the following factual background in its Certification Order:
The instant case is a suit for declaratory relief pursuant to 28 U.S.C. § 2201 brought by United States Fire Insurance Company (“U.S. Fire” or “Insurer”) against Clendenin Brothers, Inc., et. al. (“Clendenin” or “Insureds”). U.S. Fire issued the Insureds a primary general liability policy as well as an umbrella policy for the period of July 1, 1995 to July 1, 1996 to provide coverage for claims brought against the Insureds alleging injuries sustained by use of the Insureds’ welding products. Insureds presently seek insurance coverage under these policies for both the defense and indemnification of certain lawsuits that have been brought against them which allege bodily injury related to fumes caused by welding activity. [The District Court elaborated in a footnote: “The plaintiffs in the underlying suits are individuals who allege that proper use of the Insureds’ welding products produced harmful localized fumes containing manganese which caused bodily harm and *453 neurological damage.”] U.S. Fire presently seeks a declaration from this Court that it has no duty to defend or indemnify the Insureds in these welding related suits as the conditions and exclusions of the policies (specifically the total pollution exclusions) exclude such claims. Additionally, U.S. Fire seeks a determination that it has no duty to defend or indemnify the Insureds with respect to similar lawsuits filed in the future against the Insureds.
The relevant provisions of the pollution exclusion in question, which U.S. Fire asserts relieves it of its duty to defend and duty to indemnify the Insureds against the welding related claims made against the Insureds, state as follows: 1
TOTAL POLLUTION EXCLUSION
This Insurance does not apply to:
f. (1) “Bodily Injury” or “property damage” which would not have occurred in whole or part but for the actual, alleged or threatened discharge, dispersal, seepage, migration, release or escape of pollutants at any time.
Pollutants means any solid, liquid, gaseous, or thermal irritant or contaminant, including smoke, vapor, soot, fumes, acid, alkalis, chemicals and waste. Waste includes material to be recycled, reconditioned or reclaimed.
Each party filed a Motion for Summary Judgment in the District Court. Insurer argued that the language of the exclusions in the insurance policy is unambiguous, as a matter of law, and bars explicitly coverage of the claims against the Insureds. Insureds asserted that the total pollution exclusion is ambiguous with regard to manganese welding fumes and thus does not bar coverage. Concurrently with its Motion for Summary Judgment, Insureds also filed the present Motion *454 for Certification requesting the District Court to ask this Court to address, under Maryland law, the scope of the total pollution exclusion with regard to manganese welding fumes. Consideration of the cross-motions for summary judgment was stayed by the District Court pending a response from this Court regarding the certified question.
II.
We are presented here with an issue of first impression in Maryland (as well as other states): to determine whether a total pollution exclusion provision in an insurance policy relieves the policy issuer from its duty to defend and/or indemnify the policy’s holder where the alleged harm was caused by localized, workplace manganese welding fumes. Maryland appellate courts, however, previously encountered somewhat similar issues.
In
Bernhardt v. Hartford Fire Insurance Company,
The intermediate appellate court rejected the landlord’s primary argument. Conceding that carbon monoxide is a pollutant within the plain language of the pollution exclusion clause, the insured argued that “notwithstanding the literal language of the exclusion, the parties intended that it apply only to persistent industrial pollution of the environment, and not to an accident of the kind generally covered by a comprehensive business liability policy.”
Bernhardt,
*456
One year after
Bernhardt,
this Court decided
Sullins v. Allstate Insurance Company,
In finding ambiguity in the language of the pollution exclusion, we stated that “[t]he terms in the exclusion, ‘contaminants’ and ‘pollutants,’ are susceptible of two interpretations by a reasonably prudent layperson. By one interpretation, these terms encompass lead paint; by another interpretation, they apply only to cases of environmental pollution or contami
*457
nation, and not to products such as lead paint.”
Sullins,
III.
“The promise to defend the insured, as well as the promise to indemnify, is the consideration received by the insured for payment of the policy premiums.”
Brohawn v. Transamerica Insurance Company,
In determining whether a liability insurer has a duty to provide its insured with a defense in a tort suit, two types of questions ordinarily must be answered: (1) what is the coverage and what are the defenses under the terms and requirements of the insurance policy? (2) do the allegations in the tort action potentially bring the tort claim within the policy’s coverage? The first question focuses upon the language and requirements of the policy, and the second question focuses upon the allegations of the tort suit.
Thus, in the present case, we shall determine first the intended scope and limitations of coverage under the primary general liability and umbrella policies at the time of execution. Next, we shall determine whether the allegations — that proper use of the Insureds’ welding products in the regular course of business produced harmful localized fumes containing manganese causing bodily harm and neurological damage — potentially would be covered under the insurance policies as written.
When interpreting the meaning of an insurance policy under the first prong of our analytical paradigm, we construe the instrument as a whole to determine the intention of the parties.
Cheney v. Bell National Life Insurance Company,
If an analysis of the language shows that the terms used in the insurance policy are plain and unambiguous, “we will determine the meaning of the terms of the contract as a matter of law,”
Cole,
IV.
The issue of whether a total pollution exclusion clause bars coverage for injuries caused by various substances has been litigated heavily in state and federal courts in modern times.
See Meridian Mutual Insurance Company v. Kellman,
Guided by our principles of insurance contract interpretation, we conclude that the language of the pollution exclusion in the present case is ambiguous in the context of manganese welding fumes. A reasonably prudent person could construe the pollution exclusion clause in the present case as both including and not including manganese welding fumes. In
National Electrical Manufacturers Association (NEMA) v. Gulf Underwriters Insurance Company,
It seems to us, however, that an equally reasonable and prudent person could conclude, considering the character and purpose of the insurance policy and the facts and circumstances surrounding its execution, that manganese welding fumes are not included within the usual, ordinary, and accepted meaning of “pollutant.” Pollutant is defined under the policy as “any solid, liquid, gaseous, or thermal irritant or contaminant.” This construction indicates that the physical matter, whether solid, liquid, gaseous, or thermal, also must be considered an irritant or contaminant. Moreover, the *462 illustrative terms that follow (i.e., “including smoke, vapor, soot, fumes, acid, alkalis, chemicals and waste”) logically also must qualify as irritants or contaminants. Interpreting this provision otherwise would render it virtually limitless, which we conclude could not have been the intention of either party. Therefore, reading this definitional provision as a whole, we conclude that to qualify as a pollutant under the contractual definition the substance must be understood to be an irritant or contaminant.
As resorted to in Sulims, Webster’s Dictionary defines “irritant” as “something that irritates or excites” and “irritated” as “roughened, reddened, or inflamed.” Webster’s Third New International Dictionary 1197 (1993) [hereinafter “Webster’s”]. Webster’s Dictionary defines “contaminant” as “something that contaminates” and “contaminate” as “to soil, stain, corrupt, or infect by contact or association” or “make inferior or impure by mixture.” Webster’s, supra, at 491.
A reasonably prudent person might not consider manganese generally to be an irritant or contaminant. In
Bernhardt,
the insured conceded that carbon monoxide was a pollutant as defined in the policy.
Bernhardt,
As noted in an article provided in the record extract in the present case, “[n]o one denies that manganese, although essential to human health in small amounts, is poisonous in large quantities.” Jean Hellwege,
Welding Rod Litigations Heats Up; Workers Claim Toxic Fumes Cause Illness,
40 Trial Magazine 7, 14 (2004),
available at
The form taken of the manganese used here, as used in the ordinary course of the particular business involved, would not be considered by a reasonably prudent person to be excluded through a pollution exclusion provision. Insurer argues that the manganese welding fumes fall literally within the contractual definition of pollutant as it includes “any” gaseous materi
*464
al and the underlying plaintiffs allege the fumes “irritated” or “contaminated.” As a federal district court stated, “[a]ny substance could conceivably be an ‘irritant or contaminant’ under the right circumstances.”
Westchester Fire Insurance Company v. City of Pittsburg, Kansas,
The terms “irritant” and “contaminant,” when viewed in isolation, are virtually boundless, for “there is virtually no substance or chemical in existence that would not irritate or damage some person or property.” Without some limiting principle, the pollution exclusion clause would extend far beyond its intended scope, and lead to some absurd results. Take but two simple examples, reading the clause broadly would bar coverage for bodily injuries suffered by one who slips and falls on the spilled contents of a bottle of Drano, and for bodily injury caused by an allergic reaction to chlorine in a public pool. Although Drano and chlorine are both irritants and contaminants that cause, under certain conditions, bodily injury or property damage, one would not ordinarily characterize these events as pollution.
Sullins,
The development and refinement over time of the pollution exclusion provision used in insurance policies supports our conclusion that the pollution exclusion at issue was not drafted to exclude localized manganese welding fumes encountered during the normal course of business operations. In
Sullins,
we reviewed the historical development of pollution exclusions
*465
inserted in insurance policies.
3
As a direct result of the historical examination, we stated that “the insurance industry intended the pollution exclusion to apply only to environmental pollution.”
Sullins,
Determinations by other courts reviewing the historical purpose of the pollution exclusion, where the exclusion clause at issue was equivalent or similar to the language in the present case, supports this conclusion. For instance, the U.S. Court of Appeals for the Sixth Circuit noted: “[m]any courts, including the Sixth Circuit, have held that a pollution exclusion clause in a CGL insurance policy applies only to injuries caused by traditional environmental pollution.”
Kelliman,
The pollution exclusion had its inception in the 1970’s in response to federal and state legislation mandating responsibility for the cleanup costs of environmental pollution. 9 *466 Couch on Insurance 3d § 127:3 (1997). The purpose of the current version of the exclusion remains to exclude these governmentally mandated cleanup costs. Koloms, 227 ill. Dec. 149,687 N.E.2d at 81-82 . To read the exclusion more broadly ignores the insurers’ objective in creating the exclusion and ignores the general coverage provisions of the policy. Kent Farms, Inc. v. Zurich Ins. Co.,140 Wash.2d 396 ,998 P.2d 292 , 295 (2000).
Gainsco Insurance Company v. Amoco Production Company,
Finally, both the general purpose of general commercial liability insurance coverage and the specific language of this particular pollution exclusion clause demonstrate that potentially noxious workplace fumes, like the type present here, were not intended to be excluded. Under an insurance policy, the insured pays a prescribed premium, the amount of which is set by the risk to the insurer, to obtain different limits of insurance coverage prescribed in the policy. General commercial liability insurance coverage is obtained by the insured to
*467
protect itself against routine commercial hazards.
See also Tufco,
The specific language used in the total pollution exclusion clause, when read in its entirety, supports the conclusion that noxious workplace fumes were not intended to be excluded. Describing the methods of exposure to the pollutants, the policy states that the insurance does not apply to bodily harm caused by “the actual, alleged or threatened discharge, dispersal, seepage, migration, release or escape” of pollutants. In
Sullins,
we stated that the terms “discharge,” “dispersal,” “release,” “escape,” “contaminant,” and “pollutant” “are terms of art in environmental law and are used by Maryland courts to refer to environmental exposure.”
Sullins,
*468
We conclude also that the current construction of the total pollution exclusion clause drafted by Insurer was not intended to bar coverage where Insureds’ alleged liability may be caused by non-environmental, localized workplace fumes. In
Meridian Mutual Insurance Company v. Kellman, supra,
We expect that, our decision notwithstanding, interpretation of the scope of pollution exclusion clauses likely will continue to be ardently litigated throughout state and federal courts. We are aware also that courts may arrive at divergent decisions from our own within the specific context of manganese welding fumes.
See, e.g., NEMA,
*469 CERTIFIED QUESTION OF LAW ANSWERED AS SET FORTH ABOVE; COSTS TO BE EQUALLY DIVIDED BY THE PARTIES.
Notes
. The relevant language of the total pollution exclusions contained in the commercial general liability policy and the umbrella policy are indistinguishable for our purposes. The language above is found in the commercial general liability policy.
. Although this Court granted the insured’s petition for a writ of certiorari in
Bernhardt,
. During this Court's examination of the purpose of these exclusions, we highlighted, on several occasions, the historical analysis undertaken by the Court of Special Appeals in
Bernhardt. See Sullins,
. Similar to our observations regarding lead paint in
Sullins,
to ensure that localized, non-environmental workplace manganese welding fumes were excluded through the total pollution exclusion, the drafter of the insurance contract could have included explicitly a provision doing so.
Sullins,
