‘Code Grey’ declared over at the hospital in Chatham

Update: CKHA is pleased to share that the Code Grey at the Chatham Site has now been officially declared over.

The flush test of the building’s water system was completed earlier today and the results were clear which indicate we can safely resume use of the water supply. The water supply is safe to resume for drinking.

All services and programs continue to be in full operation, including the Emergency Department. The safety of patients, visitors, staff, physicians and volunteers remains the priority.


Earlier today, the water supply at Chatham-Kent Health Alliance’s (CKHA) Chatham Site and surrounding area was shut off due to work performed by the Municipality, CKHA officials say.

“Due to this work, the Chatham Site, 47 Emma building and CKHA Foundation office are currently under a Code Grey,” hospital officials said in a media release, issued at 2:01 p.m. on Tuesday, March 28, 2023.

“A Code Grey is initiated following the loss of a critical system (i.e. electricity, water, heating, medical gas, communications, ransomware, information technology etc.) or any intervention measures that may pose a health and safety risk to those in the hospital.”

Hospital officials added: “CKHA is monitoring the situation and working closely with Municipal officials during this time. CKHA has put measures in place throughout the hospital to ensure a safe water supply for its patients, visitors, staff, physicians and volunteers; this includes procuring bottled water for drinking, signage, and ongoing Code Grey overhead pages.”

All services and programs continue to be in full operation, including the Emergency Department, hospital officials say.

“The safety of patients, visitors, staff, physicians and volunteers remains the priority,” CKHA officials added.

“Further updates will be provided as the situation progresses.”

CKHA is reminding the community that the hospital remains a safe place to receive care.

If you are experiencing an emergent acute care need, please do not hesitate to dial 911 or visit your nearest Emergency Department.
