Hospitality Industry Safety Risks: Hotel Guests At Risk Of Injury As Shower Door Glass Can Shatter With The "Force Of An Explosion"

“…court records (documented)…a federal lawsuit filed earlier this year against the Four Seasons Hotel in Chicago. A woman, who stayed at the hotel in 2007, says she opened a shower door and suddenly “the force of an explosion” threw here “violently across the toilet” and caused her “serious injuries.” Pictures are filed with the lawsuit showing tiny particles of glass layered on the hotel bathroom and filling the toilet…”

Hotels need to be really vigilant about this problem…(says) a glass expert who may soon testify in three cases where guests were injured when their shower doors shattered… “The two main types of injuries are where their bodies get cut and the other ones are where they are walking out on glass and cutting their feet.”

Another couple posts video on Vimeo showing what allegedly happened to them during their Hawaiian honeymoon at the Ohana Hotel in Waikiki West. You can hear the water running from the shower, see his wife standing in the water, and feel her pain as she obviously had to find a way out through shattered glass all over the floor. The new groom, Lance Ogren, looks into his own home video camera and says, “I heard her start to open (the shower) and I heard a big crash.” Ogren tells CBS 11 news the hotel gave them an apology and a new room.

Meshulam says most shower doors have tempered glass which is heated and then cooled creating tension for durability. He demonstrated how hard it is to break slamming a hammer into a tempered glass shower door several times before it finally shatters. He says the door are considered safe because under stress they shatter into tiny pieces; however, he says there are several reasons why a shower door might explode.

One is a small crack, like the one in your windshield, that just slowly grows out like a spider web. “When it hits a certain part of the glass where all those internal tensions are residing then everything blows up.” He also says towel bars might not be installed properly. Or, doors may not slide on the tracks correctly. These can cause pressure over time. Finally, there could be a problem during the manufacturing process if a microscopic grain of nickel sulfide gets trapped inside the glass. This manufacturing defect is a “ticking time bomb.”
