A major incident has been declared following a toxic chemical spillage in a canal in the West Midlands.

Walsall Council said the Environment Agency was testing the canal water for sodium cyanide and other chemicals in the affected area.

The council warned that there would be a potential health risk to anyone who has had direct physical contact with the water in the impacted stretch of the canal.

The UK Health Security Agency has described sodium cyanide as “white crystal-like solids with a faint almond colour” and that it is used in the industry for metal cleaning, plating, extraction, and photography.

Exposure to the chemical can cause headaches, nausea, dizziness, confusion, changes in heart rate and loss of consciousness, according to the agency.

Ingesting cyanide salts, which can dissolve in water, released cyanide into the body, the agency’s website stated.

Walsall Council urged the public to avoid an extended area of the canal and towpaths from the Walsall lock flight to the lock flights at Rushall, Ryders Green and Perry Barr as a precautionary measure.

In a statement, the council said that they were notified of a spillage in Pleck by the Environment Agency on Monday that had gone directly into the canal.

Anyone exposed to the canal water in the impacted area and feeling unwell has been advised to seek health advice through calling 111 or, in an emergency, 999.

The council added that anyone who has taken fish from the canal should not eat them while drinking water and will not be affected by the incident.

Councillor Garry Perry, leader of Walsall Council, said: “Our priority is the safety of our residents.

“I share their concerns and hope to see this incident resolved as soon as possible. We are working closely with our partners to manage this situation, which has been declared a major incident.

“For your own safety, please avoid this area of the canal and its towpaths. Multiple agencies, including West Midlands Police and Fire services, the Canal and Rivers Trust, Severn Trent Water, Walsall and Sandwell councils and the Environment Agency are responding to the incident,” Walsall Council added.
