Chromium (VI)

A general fact sheet to help businesses (PCBU) manage the risks of Chromium (VI) n the workplace.

Chromium (VI), also known as Hexavalent Chromium is a toxic form of the metallic element Chromium and is typically generated through industrial processes. It can be present in solution or a solid and can be generated as a dust, fume or mist from workplace activities where chromates, dichromates and chromic acid are used.

Chromium (VI) is used as an anti-corrosive agent in paint and coatings. It can be present in pigments, Chromium catalysts, dyes and cements (Portland Cement). It is also released during chrome electroplating, during welding and hotworking on stainless steel, high chrome alloys or chrome-coated metals and is released from smelting of Chromium-containing ore.

Read our Chromium (VI) Technical Fact Sheet.

Harms

Chromium (VI), depending on factors such as the concentration and duration of use, can cause the following health effects:

  • irritation, ulceration and allergic reactions with direct skin contact
  • eye damage with direct contact (including aerosol mist)
  • irritation and damage to the respiratory tract (nose, throat and lungs) through inhalation
  • fluid build-up in the lungs, burning/itching, bleeding nose and perforation of the nasal septum

Asthma-like symptoms and dermatitis

Low concentrations of Chromium (VI) can result in workers becoming sensitised and developing allergic reactions. Allergic reactions may cause asthma-like symptoms through inhalation and contact dermatitis through direct skin contact with Chromium (VI).

Lung cancers

Exposure to Chromium (VI) through inhalation may cause lung cancers, however adequate controls such as minimising the generation of fumes, dusts and mists in addition to the use of personal protective equipment (PPE) can minimise any hazardous exposures and prevent illness in the workplace.

Controls

SafeWork NSW recommends you follow a hierarchy of controls (PDF 30kb) to eliminate or minimise a hazard.

Eliminate use of Chromium VI

Eliminate the use of materials containing Chromium (VI) if reasonably practicable.

Use exhaust ventilation or isolation

Ensure adequate engineering controls (e.g. local exhaust ventilation or isolation) are in place when undertaking high exposure activities.

Use appropriate PPE

Use well maintained and appropriate PPE such as respirators, safety goggles, chemical resistant clothing and gloves.

Train workers

Instruct and train workers in the correct fitting, use and maintenance of PPE.

Follow instructions and controls provided

Ensure that instructions and controls outlined in Safety Data Sheets (SDS), manufacturers specifications, product labels and any instructions provided by supervisors and managers are followed.

Conduct regular health monitoring of workers

Conduct health monitoring of workers, including weekly skin checks by a competent person, where there is a significant risk to health because of exposure to Chromium (VI).
