OPINION

FELDMAN, Justice.

We granted review of a court of appeals' opinion holding that evidence seized by police after a fire in a rented storage unit should have been suppressed by the trial court. Mazen v. Seidel, No. 1 CA-SA 95-0355, 1996 WL 254814, ___ Ariz. ___, ___ P.2d ___ (Ariz.Ct.App. May 16, 1996). We have jurisdiction pursuant to Ariz. Const. art. VI, § 5 ( 3) and Ariz.R.Crim.P. 31.

FACTS AND PROCEDURAL HISTORY

Around 5:00 a.m. on June 1, 1995, a tenant of a Phoenix storage facility noticed smoke emanating from another unit in the building. The storage warehouse consists of three buildings built in a U-shape, facing a common driveway. Each building is divided into separate units, but there is common attic space. Each unit has one large garage-type door, as well as a standard entrance door. Firefighters responding to the tenant's call first entered Unit 4; after determining the fire's path, they cut the lock and forced open the door to Unit 3, rented by Steven M. Mazen. The fire not only burned through the ceiling but was so hot it melted the solder on the water pipes; the resulting leak extinguished most of the fire in Unit 3.

Upon opening the door to Unit 3, the firefighters saw an elaborate system of grow lights and irrigation pipes trained on approximately fifteen singed marijuana plants. Because of his training as an emergency medical technician, the firefighter who opened the unit recognized the plants as probably being marijuana. The police were then called.

Police officers, who arrived during the clean-up operation, could clearly see the marijuana plants through the unit's open door. At approximately 6:30 a.m. the firefighters left and the arson investigator arrived. Shortly thereafter, detectives from the Drug Enforcement Bureau (DEB) arrived. The police officers and DEB detectives seized the growing equipment, the marijuana plants, and plastic garbage bags filled with marijuana. Mazen was later arrested and charged.

In a motion to suppress the seized evidence, Mazen argued that while the firefighters had a right to enter his unit to fight the fire, they were not trained to recognize and seize the plants. Furthermore, although the police may have had probable cause to request a search warrant, by the time they arrived the exigency of the situation had dissipated and therefore they could not lawfully make a seizure based merely on plain view. The trial judge rejected this argument and held, under the rationale of State v. Bell, 108 Wn.2d 193, 737 P.2d 254 (1987), that because the firefighters could have lawfully seized the marijuana, the police could step into their position and also seize the evidence.

The court of appeals accepted jurisdiction of Mazen's special action and vacated the trial judge's order, finding there were no longer any exigent circumstances when the police entered the unit. Without exigent circumstances to validate the officers' presence in the unit, the court held the plain view seizure was not lawful. Mazen, at *4, ___ Ariz. at ___, ___ P.2d at ___. The court rejected the majority opinion in Bell as too broad because it might allow any number of government officials to parade through private areas once the privacy had been lawfully breached by one set of officials. Instead, the court focused on the limiting factors discussed by the concurrence in Bell and a statement in the majority opinion that would prohibit police from "entering [or seizing] any evidence that the firefighters were not justified in seizing." 737 P.2d at 259. Because the court of appeals failed to find any statutory authority for Arizona firefighters to seize contraband, they reasoned that police officers were likewise prohibited from warrantless seizure of illegal substances in their plain view.

DISCUSSION

A. Search and seizure in Arizona

A warrantless search is unlawful under the Fourth Amendment of the United States Constitution and article II, section 8 of the Arizona Constitution unless one of the specific and well-established exceptions to the warrant requirement has been met. State v. DeWitt, 184 Ariz. 464, 467, 910 P.2d 9, 12 (1996); State v. Castaneda, 150 Ariz. 382, 389, 724 P.2d 1, 8 (1986). Exigent circumstances are one exception to the warrant requirement and include protective sweeps in response to a probable burglary in progress, a fire or medical emergency, and the likelihood that evidence will be destroyed. See Michigan v. Tyler, 436 U.S. 499, 98 S. Ct. 1942, 56 L.Ed.2d 486 (1978) ("Indeed, it would defy reason to suppose that firemen must secure a warrant or consent before entering a burning structure to put out the blaze."); Vale v. Louisiana, 399 U.S. 30, 90 S. Ct. 1969, 26 L.Ed.2d 409 (1970); DeWitt, 184 Ariz. at 467, 910 P.2d at 12; State v. Fisher, 141 Ariz. 227, 237, 686 P.2d 750, 760 (1984). This court has defined exigent circumstances as "those in which a substantial risk of harm to the persons involved or to the law enforcement process would arise if the police were to delay until a warrant could be obtained." State v. Greene, 162 Ariz. 431, 432, 784 P.2d 257, 258 (1989).

Once entrance into a private space is determined to be lawful, contraband that is in plain view, or even "plain smell," may be lawfully seized. See Horton v. California, 496 U.S. 128, 136, 110 S. Ct. 2301, 2307-08, 110 L.Ed.2d 112 (1990). However, according to our court of appeals, "the discovery of the object must be inadvertent; and its evidentiary value must be immediately apparent to the officer." State v. Kelly, 130 Ariz. 375, 378, 636 P.2d 153, 156 (App. 1981); cf. WAYNE R. LaFAVE, SEARCH AND SEIZURE § 6.7 (1978). If the officer was lawfully in the place where he saw the contraband, this court has stated that there was no real search; thus "it cannot be unreasonable or unconstitutional to seize the item in plain view." State v. Cobb, 115 Ariz. 484, 488, 566 P.2d 285, 289 (1977).

B. Lawful police presence

Lawful warrantless seizure requires that the police presence was lawful. It is uncontroverted that the firefighters opened and entered the unit in the midst of a permissible exigency — a fire in progress. The entry was not pretextual and the discovery of the contraband was entirely inadvertent. According to testimony by Kevin Riley, South Fire District Battalion Chief, had the firefighters not recognized the plants as contraband, they probably would have removed them from the unit during their cleanup operations. Part of the fire department's duties include cleaning up after a fire, salvaging property, and moving garbage and debris outside of the building. The nature of the growing operation was apparent; it was only because they recognized the plants as marijuana that the firefighters suspended their salvage efforts in the unit and instead secured the scene. When the police officers arrived, the firefighters were still on the scene. The officers took only a step or two into the unit. They were able to see the marijuana plants and the growing operation. The officers called the drug unit and remained on the scene until the drug officers arrived and removed the contraband. The case then turns on this question: Once the firefighters were finished and the exigency arguably had dissipated, could the first two officers and the drug officers again enter the unit without a warrant and seize the plants?

After the first two officers arrived, the fire department's arson investigator came on the scene and began investigating pursuant to his statutory duty. See A.R.S. § 9-500.01. It is well established that an arson investigator may search for and seize evidence after a fire and the exigency have ended, as courts have created a window within which an official's warrantless presence is lawful, despite the dissipation of the exigency. See Steigler v. Anderson, 496 F.2d 793 (3d Cir. 1974). In Tyler, the United States Supreme Court held that a warrant was not necessary for reentries, close in time to the initial exigency, by officials investigating a fire and possible arson because the "entries were no more than an actual continuation of the first entry, and the lack of a warrant thus did not invalidate the resulting seizure of evidence." 436 U.S. at 509, 98 S. Ct. at 1951.

The Tyler Court, however, addressed situations in which fire officials re-entered the premises for a purpose closely related to the exigency — investigating arson. In our case the police entered and seized evidence unrelated to the fire investigation. Several states have dealt with this question, most notably the Washington Supreme Court in Bell, 737 P.2d 254. See also State v. Loh, 275 Mont. 460, 914 P.2d 592 (1996); People v. Harper, 902 P.2d 842 (Colo. 1995). In Bell firefighters responded to a house fire caused by a woodburning stove on the main floor. Because the wall and ceiling were charred, the firefighters went into the attic to ensure there were no smoldering embers. In the attic they found marijuana plants and a growing operation. The firefighters then called police, who assisted in identifying and removing the evidence. 737 P.2d at 256. The Washington court held that the firefighters were lawfully in the attic and were justified in seizing evidence in plain view. Id. at 257. Citing a handful of federal cases, the court held that the police officers' later entry was also lawful as the defendant no longer had a reasonable expectation of privacy for that area once the firefighters had lawfully entered. Id. at 258. The court stated:

Once the privacy of the residence has been lawfully invaded, it is senseless to require a warrant for others to enter and complete what those already on the scene would be justified in doing. We hold that where firefighters have lawfully discovered evidence of criminal activity under the plain view doctrine, it is not necessary for sheriff's officers to obtain a warrant before entering a residence to seize the evidence.

Id. at 259 (citations omitted).

In the present case, the court of appeals declined to apply this concept, citing both the concurring opinion in Bell and United States v. Hoffman, 607 F.2d 280 (9th Cir. 1979). Rather than completely rejecting the Bell rule, however, the court seized upon the Washington court's statement that the police "cannot enter any area that the fire fighters were not justified in entering, nor seize any evidence that the fire fighters were not justified in seizing." Mazen, at *3, at ___, ___ P.2d at ___; Bell, 737 P.2d at 259. The court of appeals held that although a fire marshal or arson investigator may seize evidence of arson, he had no authority to seize other evidence of crime. Thus, the police officers could not "step into the shoes" of the firefighters to lawfully seize the marijuana. Mazen, at *3, at ___, ___ P.2d at ___,

We believe this argument is incorrect. Whether or not firefighters are permitted to seize evidence not related to arson, part of their duties includes moving and salvaging property in fire-damaged areas. During the hearing on the motion to suppress, Battalion Chief Riley stated:

Well, the other thing that we look at doing is our loss control effort. And those are trying to, you know, minimize damage and trying to do the most that we can in order to salvage or prevent damage to the belonging of the property of that particular occupant, which would be covering up things, because even after we have the fire knocked down, we still have to — what we have to do is overhaul. We have — a lot of our overhaul procedures, we are going to have to do access operations. We still need to pull ceiling. We need to pull walls to make sure that the fire isn't burning into the insulation or down into walls. Oftentimes, those are the kinds of activities that we have to do, you know, before the job is completely done. And then we also like to wrap all the stuff up and all the refuse, garbage and things that have been burned up and stack it outside so it can be picked up by, you know, a refuse company so they can haul it away.

* * *

We don't leave until we call the occupant services. And again, it is part of our loss control effort. But we don't leave until after we have picked up; we have got all your salvage cover laid out; we have picked up all the burnt debris and garbage. We shovel it into carryalls and stack it outside.

Transcript of Evidentiary Hearing, Nov. 17, 1996, at 18-19. The firefighters would have been justified in removing the plants to a location outside of the unit where the police could have seen them and legally seized them. Instead, recognizing the nature of the plants but unsure about evidentiary procedure, the firefighters simply called the police and maintained the scene until the officers stepped into the firefighters' shoes to enter and move the marijuana plants. Because the firefighters' warrantless entrance was proper, the police officers' later entrance and warrantless seizure of contraband in plain view did not violate the Fourth Amendment or article II, section 8 of the Arizona Constitution. While fire clean-up and investigation was still occurring, the police did no more than enter where the firefighters had entered and seize contraband the firefighters could have carried out and laid at their feet.

The police could lawfully step into the shoes of the firefighters to seize what the firefighters could move. Mazen "no longer had a reasonable expectation of privacy for that area . . . where one officer" was already legally present. Bell, 737 P.2d at 259. Had the police been the first to respond to the fire, or had it been necessary for the police to aid the firefighters, the officers would have been able to enter the building because of the exigency and see the contraband. Police officers often fill many roles, including paramedic, social worker, and fire investigator. See United States v. Brand, 556 F.2d 1312 (5th Cir. 1977) (police aid in emergency drug overdose); State v. Jones, 188 Ariz. 388, 396, 937 P.2d 310, 318 (1997) (police checking on welfare of siblings of abuse victim enter trailer and see blood-stained towel). Thus, it is not unreasonable to allow them to step into the shoes of those people when those roles overlap the role of criminal investigator. As Bell indicates, all the cases that have considered this issue have so held, with the exception only of Hoffman, 607 F.2d 280. We agree with Hoffman that citizens need not expect that the initial, lawful entry of one agency justifies successive, unrelated, and warrantless entries by officers of other agencies. Id. at 285. We do not believe, however, the subsequent police entry in this case was either successive or unrelated. The officers arrived while the firefighters were on the scene. It would, we think, exalt form over substance to hold that when other government agents have legally entered the premises, with power and responsibility to remove and handle property, police could not also enter while the first agents were still engaged in their work and seize what was in plain view and plainly contraband. See Bell, 737 P.2d at 257-59. Such a rule would serve no interest protected by the prohibition against unreasonable searches and seizures and the warrant requirements of the state and federal constitutions. Nor would it further the privacy interests protected by article II, section 8 of the state constitution to hold that the police could not enter the same room in which the firefighters were still working and see what the firefighters could see.

C. Delay between the discovery and the removal by the police

We have previously stated that on expiration of the exigency justifying the warrantless entry and search, and absent something more than mere suspicion that the items in plain view were contraband, there is no justification for continuing the warrantless search. DeWitt, 184 Ariz. at 467, 910 P.2d at 12 (citing State v. Cook, 115 Ariz. 188, 194, 564 P.2d 877, 883 (1977)). In DeWitt we concluded that the evidence should be suppressed. But there are two significant distinctions to be made between the present case and DeWitt.

A police officer investigating a possible burglary at DeWitt's home, while making a sweep of the house, saw glass vials and equipment on the top shelf of a closet. He was suspicious and called in his partner to take a look. Because both officers were uncertain whether the items were used to manufacture drugs, they called in DEB officers. One of the DEB officers had to stand on a stool to clearly see the items.

The evidence seized at DeWitt's home was not clearly contraband, as evidenced by the first two officers' inability identify it. Second, the evidence was not in plain view, as the DEB officer had to stand on a stool to see far enough into the closet to determine the materials were evidence of drug processing. DeWitt is a case of successive entries by officers who at first had not found obviously illegal materials in plain view and called in help to confirm mere suspicions. This court assumed without deciding that the second warrantless entry by the fist officer's partner was lawful. Id. at 466, 910 P.2d at 11. However, we held the later entry by DEB officers was an unlawful confirmatory search. Id. at 468, 910 P.2d at 13.

In the case at hand, the contraband was in plain view and its nature immediately apparent. Although there were entries by various police officers as part of the process to remove the evidence, the initial seizure occurred when the firefighters recognized the illegal nature of the plants and called in the police to remove them from the premises. The first officers stayed on the scene but would have been justified in seizing the contraband the moment they first entered and saw it. We are unwilling to say that their delay in physically seizing it because of safety, bureaucratic considerations, or logistics — such as waiting for the arrival of the DEB officers or their truck — would then prevent them from taking the evidence once these problems were solved. From the moment of the firefighters' clearly appropriate warrantless entry to the moment the plants and equipment were loaded in the DEB truck, there was never a time when the unit's door was closed or a firefighter or police officer not on the scene. In sum, from the moment the firefighters arrived, there was never a time when Defendant regained his expectation of privacy.

Furthermore, in State v. Girdler, this court cited with approval Tyler's holding that conditions at a fire scene may delay a permissible search. 138 Ariz. 482, 485, 675 P.2d 1301, 1304 (1983) ( citing Tyler, 436 U.S. at 509, 98 S.Ct. at 1951). The present case is not one of successive entries by different governmental agencies to confirm a mere suspicion; nor is it one in which officers of the second agency exceeded the proper temporal or spatial boundaries of the original entry. Thus, we find the seizure of the marijuana plants and the growing equipment was lawful and the evidence is admissible.

D. Seizure of the bagged marijuana

The first police officer who responded to the firefighters' report of the marijuana entered about two feet into the unit to determine whether the plants were marijuana. He then called a supervisor, who informed DEB and arranged for a truck to pick up the evidence. When the DEB officer arrived to assist in the seizure, he smelled the odor of burning marijuana behind a box of lights the officers were seizing. He moved the box to reveal a garbage bag that had been partially burned open. Inside the bag he could see smaller baggies filled with marijuana, which he seized.

Ordinarily, smelling burning marijuana is in itself an exigent circumstance justifying the warrantless entry into a building. State v. Kosman, 181 Ariz. 487, 491, 892 P.2d 207, 211 (App. 1995); see also Vaillancourt v. Superior Court, 273 Cal.App.2d 791, 78 Cal.Rptr. 615 (1969) (smell of burning marijuana indicates the evidence is disappearing). However, as discussed above, no such exigency was required to allow the officers to be where they were; they were already lawfully in the storage unit. As they were moving a box of lighting equipment they were justifiably seizing, the bags of marijuana came into view. This is a different type of search than occurred in Arizona v. Hicks, in which the officer moved an otherwise unsuspicious stereo to look at the serial numbers and thereby determine whether it was stolen. 480 U.S. 321, 324, 107 S.Ct. 1149, 1152, 94 L.Ed.2d 347 (1987). Thus, even though there was a plain smell of marijuana that would have justified a broadening of the search, the seizure of the bags of marijuana was also a continuation of the original search and seizure and in plain view. We find no Fourth Amendment concerns that would prevent seizure of the bags of marijuana.

CONCLUSION

Firefighters' duties include salvaging property in fire-damaged areas. Even if firefighters and arson investigators may not be charged with the authority to make seizures based on criminal activity, they would have been justified in removing the marijuana they saw in the storage unit. Instead the firefighters maintained the crime scene and the police officers stepped into the shoes of the firefighters to enter and move the marijuana plants. Although the first officer on the scene did not make the physical seizure, he lawfully could have done so.

We view the situation presented by the facts of this case differently from the dissent and fear the dissent therefore paints the opinion too broadly. We do not hold, as the dissent argues, that Mazen lost his reasonable expectation of privacy because "a state agent's initial presence was lawful." Dissent at 203, 940 P.2d at 931. Rather, we hold that Mazen lost the expectation of privacy only for objects in plain view and only because the state agents' initial and continued presence was lawful. Nor do we see two searches that "were entirely separate, requiring two separate justifications." Dissent at 203, 940 P.2d at 931. There was no search of any kind except that incident to putting out the fire (opening the door of the unit), and only a seizure of contraband in plain view. The contraband was in plain view at the time the firefighters entered, while they were there fighting the fire, and when the first police officers arrived. Unlike DeWitt, this is not a case of separate entries and successive confirmatory searches. The firefighters were aware of the contraband when they first entered and left it in the unit, instead of moving it outside and presumably handing it to the first officer to arrive, only because they wished to leave the chain of evidence to police procedures.

Thus, we do not authorize consecutive entries and searches, even if confined to the physical boundaries of the initial entry. In the present case, the police entry was confined by both spatial and temporal boundaries of the firefighters' entry, presence, and plain-view discovery. The firefighters were still on the scene doing their work when the police first arrived. From that point forward, the police remained on the scene, with the door open, waiting for the DEB truck to arrive.

The dissent argues that the existence of probable cause does not justify a warrantless entry, search, or seizure absent exigent circumstances. We agree, but in our view, the whole case turns on the officers' lawful right of access. The firefighters entered under exigent circumstances. We hold that the officers, responding to the firefighters' call, could also enter while the firefighters were still on the scene, performing their customary work. Confining themselves to the physical boundaries of the area in which the firefighters were working and making no additional inspection or search, the police could seize contraband in plain view. If, as we believe, these acts were legitimate and lawful, then everything that transpired afterward, including the subsequent discovery of the burned or charred trash bags full of marijuana baggies, was lawful. We are unwilling to say that the delay because of safety considerations or logistics would then prevent the police from seizing the contraband once these problems had been solved. Thus, we find all the seizures were lawful and the evidence is admissible.

The court of appeals' opinion is vacated. The trial court's order denying suppression is approved. We remand for further proceedings consistent with this opinion.
