Risks Associated With Thermal Spray Equipment And Use
As mentioned, there are countless uses for thermal spraying processes. To keep things simple, we’ll start by breaking them down into the different sorts of processes that fall within the category addressed in the blog. In the chart below, you can locate the process or processes used in your own workspace.
There are a number of distinct risks that are associated with each of these types of thermal spraying, including:
- Ultraviolet Light: Thermal spray systems product UV light, defined as non-ionizing radiation. The spectrum varies depending upon the type of process used. For example, flame spray processes produce such radiation in the UV-B or erythemal region of the electromagnetic spectrum. Plasma systems, on the other hand, operate with much greater intensity in the UV-C region. With prolonged exposure, such radiation can damage the eyes (flash burn), burn the skin, and cause changes in skin cell growth.
-
- Fumes and Dust: Another byproduct of the thermal spray process, dust and fumes created by atomized molten metals, can pose significant health and safety hazards. Not only do they form a potential combustion risk, but they are also hazardous if inhaled, causing a variety of negative reactions.
- Compressed Air: Aside from the well known danger when directed at unprotected skin or eyes, compressed air that is not properly regulated poses a number of other risks. Its noise levels can often cause hearing loss. Additionally, it is imperative to maintain the good condition of equipment, as damaged hoses can lead to explosion.
- Fumes and Dust: Another byproduct of the thermal spray process, dust and fumes created by atomized molten metals, can pose significant health and safety hazards. Not only do they form a potential combustion risk, but they are also hazardous if inhaled, causing a variety of negative reactions.
- Industrial Gases: The list of gases used in thermal spray processes is extensive, including: argon, helium, hydrogen, kerosene, and oxygen, among others. Each of these gases carries with it its own dangers. Many are flammable, corrosive, or pose the risk of combustion. Additionally, many are toxic when inhaled.
OSHA Safety Recommendations
Recognizing the numerous risks associated with thermal spray processes, the Occupational Safety & Health Administration has outlined a number of regulations and recommendations to keep you, your workers, and your workplaces safe.
First and foremost, owners and operators of such spraying equipment should understand and implement the operational procedures outlined by the product’s manufacturer. Additionally, all of OSHA’s standards on Welding, Cutting and Brazing should be heeded. Although they are numerous, the outline below will give you a basic idea of what steps can be taken to reduce this risks described above.
- Ultraviolet Light: Ensure that operators, assistants, and others in the vicinity of thermal spraying use the appropriate protection for their eyes and skin. This clothing should be tightly woven, including both gloves and coveralls. Additionally, tinted welding curtains and screens can reduce exposure to nearby workers.
- Fumes and Dust: To reduce the risk of various dangers associated with fumes and dust, make sure that you have a dust and fume collection system that is fitted to the necessary specifications. If you are working with toxic materials, HEPA filters may be necessary. In addition to an industrial dust collection system, it is also important to establish a respiratory protection program for workers, including proper fitting of respirators and regular medical screenings.
-
- Compressed Air: In addition to following manufacturer provided safety instructions for any compressed air, be sure to regularly inspect all of your equipment and follow the best practices for use. Not only will this promote safety for those using it, but it will also ensure the efficiency of the work being done.

- Industrial Gases: Along with the safety precautions described for fumes and dust, it is also important to conduct regular air sampling to determine workers’ exposure to airborne contaminants. This is especially important when the gases being used in your manufacturing processes are potentially toxic; thermal metal spraying and practices like it can create fumes and gases at concentrations exceeding their Permissible Exposure Limits.
A Valuable Solution For Thermal Spraying Dusts, Fumes, and Gases
Although some safety precautions–such as eye protection and respirators– may be easy to address, an industrial dust collector is a very different kind of solution. A larger investment, such collectors require you to take a full assessment of your workplace to determine the specifications you will need. Not only do you have to consider the safety provided by this system, but you also need to think about its efficiency and ease of use.
