When it comes to blacking your workplace equipment, nickel sulphate is a necessary part of that blacking experience. However, what has been used as the go-to compound has now been found to be extremely dangerous with seriously harmful effects on the body. Nickel sulphate has been the standard blacking technique, but there are now alternatives that can give you the same results without the danger. Here are a few of the reasons why you should find alternatives to this nickel substance today.


First and foremost, nickel is a carcinogen, meaning that it can cause cancer in people who have been exposed to it, in this case through inhalation. When this nickel is found in airborne particles that are then inhaled into the body, it can cause serious harm, including cancer to the respiratory system, which can of course be life threatening and many believe there is no safe exposure amount that will not cause this result. Don’t put yourself or any other worker in a position where they have to choose between their life and their job. Find alternative blacking methods today and keep everyone safe.


Because nickel sulphate can be absorbed through the skin, there is a high risk that overexposure could lead to infertility in male workers. While this may not be a life threatening issue, it definitely affects a person’s quality of life and can lead to serious issues later on down the road. However, if exposure is addressed early enough, the symptoms can be reversible. However, is that really a risk you’re willing to take?

Breathing Issues

When inhaled regularly, this nickel substance can cause serious damage to the nose, throat, and lungs which could cause coughing, shortness of breath, and even asthmatic like symptoms such as chest tightness. If dramatic exposure has been experienced, it could very well lead to permanent scarring of the lungs. This will have a direct effect on a person’s ability to work and the productivity of the company with who they are employed.


Many companies are now searching for alternative blacking methods that exclude or severely minimise the use of nickel in their compounds. For example, while standard blacking methods require the substance to be sprayed in an aerosol type canister, there are options where the nickel is kept in solid or liquid form, making sure airborne particles are not possible. Because the nickel isn’t agitated in any way, there should be no reason to be concerned about possible side effects whatsoever.

Of course, blacking of machinery is necessary to ensure the safety of workers in the manufacturing industry. However, it’s time to find alternative methods of blacking that keep workers safe from harm rather than in direct exposure to it.
