What is Nickel Sulphide? (NiS)

Nickel Sulphide (NiS) is a contaminant that can be found in glass and can lead to spontaneous glass failure.Generally only tempered (toughened) glass will contain this as a potential risk.

A Nickel Sulphide inclusion in the glass structure can change state at an unspecified point causing total failure of a pane. Considerations for owners and tenants of a building that may contain Nickel Sulphide:

  • Public safety
  • Workplace Health and Safety
  • Tenant issues
  • Media interest
  • Insurance and litigation
  • Building’s value
