What actually is nickel?

Nickel is a silvery-white metal that is relatively common in nature and plays a role in a wide variety of processes.

As a natural mineral, nickel occurs in various regions. But most of the world’s nickel resources can be found in countries like Indonesia, Canada, Russia, and Australia. It is also mined in South Africa and other parts of the world.

In which industries is nickel used? And for what?

Nickel is used primarily in the metalworking industry, meaning that nickel dust is produced in workplaces that produce or use nickel and nickel compounds in mining, smelting, welding, casting, and grinding.

It is also used when different alloys are produced. For example, in the production of jewellery, coins or other metal objects. You can even find nickel in stainless steel.

At what point does nickel dust become a danger to employees?

If you work with nickel – regardless of whether it is melting, welding, casting, or grinding – toxic nickel dust is produced. Its so-called toxicity level, however, depends on how easily the nickel compounds dissolve.

Even brief, unprotected contact with nickel dust can be dangerous.

For example, the first symptoms include:

  • Irritated eyes,
  • Irritated skin,
  • (Severe) allergic reactions,
  • Breathing problems.

But any type of fine dust can also have a negative impact in the long term, contributing to more serious illnesses like:

  • Asthma,
  • Pneumonia,
  • Lung and nose cancer (sinuses).

According to the Agency for Toxic Substances & Disease Registry cases of lung and sinus cancer occur when employees are exposed to more than 10 mg nickel/m³.

This is also confirmed by the US Environmental Protection Agency (EPA), which classifies nickel refinery dust and nickel subsulfide (based on studies) as carcinogenic to humans.

What protective measures should be taken against nickel dust?

First and foremost, companies should not assume employees are aware of the risks associated with nickel dust – awareness is key.

Here are 6 pointers to help you mitigate the risk:

  • Ensure all smoke and dust control devices are in good working order.
  • Check the fit of all tight-fitting respirators.
  • Measure the nickel exposure in your company regularly and pass the results on to your employees.
  • If necessary, carry out health checks within your team (e.g., by the company doctor).
  • Train your employees to understand the risks of nickel exposure and how to avoid them.
  • Reduce exposure to airborne nickel by providing the correct protective equipment.

But for the best results, you should extract nickel dust directly at the source with our market leading air cleaning systems.
