Sandals Hotels & Resorts says it is ‘devastated’ by the recent death of three people from carbon monoxide poisoning at the company’s Emerald Bay Resort in Exuma, Bahamas, and will place CO monitors in all guest rooms across its portfolio and undertake an extensive review of the property.

The devices have already been installed in rooms at Emerald Bay where three guests, including two travel agents from Tennessee, became ill earlier this month and subsequently died. A fourth guest is recovering.

Investigators and health officials blamed what Sandals called an “unimaginable event” on a reaction to carbon monoxide, a colourless, odourless, tasteless gas, but assured that the incident was not a public health concern.

“Despite initial speculation, Bahamian authorities have concluded the cause was an isolated incident in one standalone structure that housed two individual guest rooms and was in no way linked to the resort’s air conditioning system, food and beverage service, landscaping services, or foul play,” Sandals said in its statement.

It added, “Ensuring the safety and well-being of our guests and team members is and will always be paramount. It is for this reason that we have taken additional measures such as engaging environmental safety experts for a comprehensive review of all systems across the resort.”

“We wish to extend once again our deepest sympathies and our heartfelt condolences to the Phillips and Chiarella families,” the statement continued. “Our entire team keeps the families in our thoughts and prayers during this difficult time.”
