Non-sparking tools: Common Misconceptions You Need ...

The following are some of the misconceptions about non-sparking tools that we have come across through interactions with industrial companies:

1. Non-sparking tools do not generate any spark

Non-sparking tools are made of metal and, consequently, they do generate sparks. The key difference between non-sparking tools and steel tools is the energy of the spark they produce. The reduced energy of these sparks is attributed to the specific alloys used in crafting non-sparking tools.

2. Copper Beryllium (Cu-Be) tools are more expensive than Aluminum Bronze (Al-Bron) tools

Although Cu-Be tools are approximately 30% pricier than Al-Bron non-sparking tools, they are 40 to 50% more durable. Thus, over time, Al-Bron non-sparking tools could turn out to be the more costly option due to the frequency of replacements. Depending on their usage, Cu-Be non-sparking tools may prove to be a more cost-effective choice in the medium to long term.

3. Plastic coated tools are safe to be used in explosive work environments

While plastic-coated tools are arguably safer than steel tools, they cannot be deemed entirely safe since it's impossible to coat all active parts of a tool. Consequently, these tools are called spark reduction tools but not non-sparking tools. Their usage is discouraged for several reasons:

  • They do not mitigate the risk of explosions.
  • The plastic coating can get damaged, thus increasing exposed areas.
  • Standard EN 1127-1 restricts the use of steel tools in most gas zones and groups.

4. Cu-Be non-sparking tools are carcinogenic and therefore represent a health hazard

There is much confusion regarding the health risks posed by Cu-Be non-sparking tools. Prolonged inhalation of beryllium dust, which is known to cause lung cancer, often occurs in foundries where this alloy is melted without proper safety measures. However, there are no documented cases of cancer directly stemming from use of Cu-Be non-sparking tools because:

  • Cu-Be tools contain only 2% beryllium.
  • They do not produce powdered beryllium, limiting exposure to inhalation.
  • Overall exposure is minimal.

For this reason, no country has banned the use of this alloy

5. Cu-Be non-sparking tools are always the safest option

Though Cu-Be non-sparking tools are usually the safest choice, they are not suitable in environments containing Acetylene gas. Acetylene, although in the IIC gas group, reacts with any alloy having more than 65% copper, forming a highly explosive compound known as copper acetylide. Given that both Cu-Be and Al-Bron alloys contain over 80% copper, they must not be used in Acetylene environments. Instead, specialized steel tools would be safer in such scenarios. EGA Master has developed an alloy called ACETILEX®, with less than 65% copper, making ACETILEX® non-sparking tools the only entirely safe option for working in environments with Acetylene.

Non-sparking tools: The must-have safety tools

What is a non-sparking tool?

A non-sparking tool (also referred to as spark-resistant or spark-reduced) is a tool that is only capable of producing a cool or low energy spark. This is due to the fact that, unlike steel tools, non-sparking tools are manufactured from metals that absorb heat. These include copper and brass tools, as well as any beryllium non-sparking tool.

Although a non-sparking tool is technically capable of generating a spark, the spark produced from these types of tools is so low in temperature it wouldn’t be capable of igniting. This makes non-sparking tools safe to use in environments where flammable gases or materials present a health and safety risk.

Where are non-sparking tools used?

Non-sparking tools are used when the job or environment presents a high risk of fire or explosion. For this reason, you’ll find non-sparking tools used in a wide range of commercial industries, most significantly in sectors that process flammable chemicals, materials, or gases, such as hydrogen.

This can include the production and manufacture of things such as fireworks, paint, explosives, and pharmaceuticals. You’ll also find non-sparking tools widely used throughout the oil and gas industry, such as in oil refineries and on offshore oil rigs at sea.

Coal mines and grain silos are other places where non-sparking tools are commonly used.

What are non-sparking tools made of?

Non-sparking tools are made from metals that only produce a cool or low energy spark. These include brass and bronze as well as copper-based alloys such as copper-nickel, copper-aluminium, or copper-beryllium, with copper being the primary component.

Non-sparking tools can also be distinguished from regular tools by the fact they don’t contain any steel. That’s because this metal type, commonly used in the production of tools, is known to produce hot sparks at temperatures capable of igniting flammable gases.

Tools made from steel, therefore, are unsafe to be certified as non-sparking, which is why steel is not a metal used by non-sparking tool manufacturers.

Must-have non-sparking tools

Hammers

Steel hammers can easily generate sparks during striking. Using a non-sparking hammer, such as those made of copper beryllium, will ensure you stay safe in environments where sparks can cause flammable liquids or gases to ignite.

Wrenches

Non-sparking wrenches will help you to tighten and loosen nuts and bolts safely in environments where flammable materials represent an explosion risk.

Pliers

Non-sparking pliers are an essential tool for maintaining operational health & safety standards in industries such as oil and gas.

Scrapers

A non-sparking scraper is the perfect tool to turn to if you need to remove gravel, dirt, or other substances from the ground in hazardous conditions.

Sockets

If you’re using a ratchet and socket for a job that presents a high risk of explosion, it’s essential that the tool you use is manufactured from a non-sparking metal.

Screwdrivers

Non-sparking screwdrivers in a range of sizes can ensure you’re always able to remove or affix screws safely when working near flammable substances.

How to maintain copper-beryllium non-sparking tools?

Non-sparking tools require a little more care than those made of iron or steel. However, you can easily maintain copper-beryllium tools in the following ways:

  • Avoid dropping or throwing the tool. Always place it down carefully after use.
  • Make sure you always select the most appropriate tool for the job to reduce tool slips.
  • Always clean non-sparking tools after using them to prevent contamination.
  • Check the condition of your tools regularly for deterioration – especially the tools you use most often.
  • When using non-sparking hammers, make a conscious effort not to overstrike.
  • Keep copper-beryllium tools clear of corrosive substances that can compromise their non-sparking properties.
  • When sharpening non-sparking tools, always wear appropriate PPE such as safety goggles, gloves, and a face mask.
  • Always keep your non-sparking tools separate from other tools.

Conclusion

Non-sparking tools are essential for any job that brings you into close contact with, or proximity to, flammable materials. They’re also a health and safety necessity when working in industries with a high explosion risk, such as oil & gas.

It’s never worth using a traditional tool in a situation where you should be using a non-sparking tool. Not only could you jeopardize your own safety, you also put other lives at risk.

Like all responsible tool manufacturers, at Red Box we offer a range of non-sparking tools in a variety of certified non-sparking metals. You’ll find the full range, which includes Bahco non-sparking tools, on our website.

FAQs

Is stainless steel considered non-sparking metal?

No. Stainless steel is not considered a non-sparking metal.

Does copper cause sparks?

Copper can produce sparks but only cold sparks. Copper quickly absorbs heat, which is why it’s one of the primary metals used in the manufacture of non-sparking tools.

Can aluminium make a spark?

Yes. Pure aluminium can spark. Aluminium alloys such as copper-aluminium, however, are considered non-spark, providing copper is the primary metal.

Who uses non sparking tools?

Non-sparking tools are used in industries such as oil and gas, pharmaceuticals, coal mining, and grain silos, as well as in the production of fireworks, explosives, and paint manufacturing.

What makes a tool non-sparking?

A tool is non-sparking if it is made from a non-sparking classified metal such as bronze, brass, copper-nickel, copper-aluminium, or copper-beryllium.
