- Two hospitalized for smoke inhalation
 (CNN)
Flames
 and thick plumes of black smoke from a quick-spreading fire engulfed 
the 14th-floor pool deck of a sprawling Las Vegas Strip resort Saturday. 
Videos posted on social media showed 
the inferno consuming the poolside tent-like cabanas, imitation palm 
trees, and just about everything else on the open-air deck of the 
Cosmopolitan of Las Vegas hotel.
An 
unknown number of guests and employees at the 3,000-room resort were 
evacuated. There were no serious injuries, but two people suffered smoke
 inhalation, according to Clark County Fire Chief Greg Cassell. 

Pool deck fire at Las Vegas hotel caught on camera 02:13
Amy
 Rossetti, vice president of public relations for the Cosmopolitan, said
 the fire started at about 12:15 p.m. (3:15 p.m. ET) and was contained 
to the Bamboo Pool, located in the resort's west end tower. 
"The pool was fully loaded," Cassell said.  
Fire ''took off like a rocket'
The fire chief said that in 26 years on the job he'd seen his share of casino fires, but never one quite like this one. 
"What
 made it move so fast were all the fake palm trees," Cassell said. The 
plastic foam used to construct the imitation Arecaceae "is like solid 
gasoline to us," he said. That's why the fire "took off like a rocket."
Mike
 Naumann was staying in the Aria Resort and Casino in Las Vegas when the
 fire engulfed the pool deck of the Cosmopolitan. He was able to capture
 this video of the fast moving fire outside of his window.
Corbin
 Williams, a guest staying on the 14th floor, described a chaotic scene.
  "Alarms started going off and it became really chaotic.," Williams, 
from Los Angeles, told CNN,  "It's pretty crazy over here. There are 
fire trucks everywhere." 
Matt Mills, 
who was sharing a suite with Williams, shot video through the door 
leading to the pool as the evacuation was underway. 
"This is unbelievable. Unbelievable," Mills is heard saying on the video. 
Cassell said that several rooms on the 14th floor sustained heat damage, but the fire never got into the hotel itself. 
Cause under investigation
Clark
 County fire spokeswoman Sandra Baker said, "Early preliminary reports 
indicate a landscaping fire," but that investigators were still looking 
into the cause.  Cassell said an electrical fire was also possible due 
to the amount of decorative lights festooned about the fake palms. 
Williams,
 however,  said his experience at the pool a day earlier left him with 
an unsettling premonition that it might have been something else. 
"I
 noticed cigarette burn holes in my cabana's roof, I assumed they had 
been flicked from above balconies," he said. "And I had that exact 
thought, that these things could catch on fire."
Williams,
 who said he was staying in a complimentary suite because of "issues we 
had the last time we stayed (at the hotel)," nevertheless remained 
upbeat.
"Cosmo is one of the best places to stay, in my opinion," he said. "You know, except for the last two times."
