Static electricity can cause serious problems within the manufacturing environments from product quality issues to worst case scenario sparks being generated risking fire and explosion.

What causes static electricity?
Static electricity is caused when two materials rub against each other. Typically, the surface of every material has both protons(+) and electrons (-), with their charges being balanced; meaning the overall object has a neutral charge. However, when two objects rub against each other, the charges are separated and an electron or proton can move from one object to the other, resulting in each object becoming either positively or negatively charged. These objects will then attract (or repel) other objects.

So why is this a problem?
If two objects with a different electric potential are placed close together and if the voltage difference is sufficiently high, a spark can occur. Sparks can cause a serious risk of fires and explosions especially in environments where there are flammable materials or in environments where there is a lot of dust or fine powders.

While the creation of a spark is the most serious result of static electricity, static electricity can also interfere with the production process in other ways such as:

  • dust contamination
  • products clinging to each other
  • contaminants getting into product
  • plastic sheets not separating properly
  • potential damage to machinery
  • shocks to operators

What factors affect the creation of static electricity?

  • The weather
    The dryer the air the greater the static build-up. Controlling the atmosphere in your production facility can reduce the risk of static electricity build-up.
  • The type of materials being used
    Some materials are more readily charged than others. For example, materials such as acetate will gain a charge very readily whilst glass will gain a charge less readily.
  • Repetition
    Repeated actions such as constant friction or separation will increase the level of charge found on a material. For example, a plastic web moving over a series of Teflon rollers will increase its surface charge after every roller.
  • Battery Effect
    The combination of many charged items can lead to extremely high charges. For instance, individual sheets of plastic with relatively low surface charges when stacked together can generate extremely high voltages.
  • Change In Temperature
    As a material cools down it can generate charge.

Controlling static electricity
While the generation of static electricity cannot be stopped, its accumulation and dispersal can be controlled through:

  • correctly designing machinery, pipes and filtration systems
  • bonding and grounding of equipment
  • humidity control
  • additives – antistatic additives can be added to liquids such as fuel to increase conductivity and reduce electrostatic build-up
  • Material, flooring and clothing – conductive flooring, shoe soles and clothing can help dissipate static charges from a person as they walk or move around
  • the introduction of Ionisers to your production line.

What are Ionisers
Air Ionisers make the air sufficiently conductive to dissipate static charge. Whatever static charge is present on objects in the work environment will be reduced and neutralised by attracting opposite polarity charges from the air. Because it uses only the air that is already present in the work environment, air ionisation may be employed even in cleanrooms where chemical sprays and some static dissipative materials are not usable.


Some ionisation devices require airflow to operate properly and may incorporate fans in their design.

In electrical engineering a hazardous area is a place where a fire or explosion hazard may exist due to:

  • flammable gases or vapours
  • combustible dusts or ignitable fibers

which may be present in the air in quantities sufficient to produce explosive or ignitable mixtures.

Where are hazardous areas found?
Places like oil refineries, chemical plants and sewerage treatment plants are areas where hazardous gas vapours may be present; however, many companies don’t realise dust can also create hazardous areas in places such as food and beverage manufacturers, plastics factories and recycling operations.

Typical industries with hazardous areas


Due to the risks associated with these hazardous areas, staff accredited with an EEHA qualification need to take responsibility for installing and maintaining any electrical equipment in these areas.

EEHA qualified people can:

  • identify hazardous areas
  • understand hazardous area drawings
  • understand explosion protection techniques
  • are skilled in equipment installation in these areas
  • are familiar with procedures for breakdowns and the maintenance of equipment in hazardous areas
  • ensure all hazardous area dossiers are updated.

The electrical equipment installed in these areas must also be specifically designed and tested to ensure it doesn’t cause an explosion either due to arcing or its high surface temperature.

When installing electrical equipment in hazardous areas it is essential that:

  • Checks are done of existing hazardous area inspections and drawings.
  • A hazardous area drawing and dossier is created, if it does not already exist.
  • All electrical equipment to be installed carries ICE/Ex certificate.
  • Installation of new equipment is carried out by EEHA qualified electricians.

EAS can coordinate the whole process of maintaining and installing electrical equipment in hazardous areas for you. From inspections, drawings, installation, testing and certification. EAS can deliver you a complete turnkey solution.

If you’re planning a new equipment installation in your plant, which is classed as a hazardous area, or need to conduct maintenance on equipment in hazardous areas; get in touch with the EAS team today on 07 834 0505.

When it comes to safety precautions and installation practices in hazardous areas, our team does not cut corners.

Industrial Electrical Motors

Electric motors have been around for centuries, becoming more refined and powerful over the years. Their role is to convert electrical energy into mechanical energy used in everything from your household appliances and computers to powering mega factories around the world.

The first motors were developed as far back as the 1740’s, however due to the challenges in generating the high voltages they needed for operation, these motors were never used for any practical purposes.

DC motors made a rise through the 1830’s, running up to 600 revolutions per minute, they powered basic tools and presses.

By the 1880’s the modern AC electric motor was taking shape, able to be adapted to many applications.


Today there is a wide variety of electric motor options for your plant. Key factors to consider when making your selection include:

  • Input power source
  • Environment – will the motor be operating in areas where it would be at risk or dust or water contamination or extreme temperatures. Is it located in a Hazardous Area?
  • Motor specifications – the weight, size, shape can all have an impact on the suitability of the motor for the job.
  • Motor performance – the speed and torque, starting/stall torque and the load profile will all impact on whether the motor is the right fit. A motor that has not been matched appropriately will cause significant damage to the machine, likely resulting in stalling or failure.

The EAS team can work with you to help take the guesswork out of choosing the right motor for your application.

To ensure the longevity of your motor, maintenance is also a key consideration. Over their lifespan of your motor, both mechanical and electrical inspections should be carried out to help identify issues such as:

  • High resistance connections – Terminal box
  • Winding contamination
  • Rotor bar faults
  • Bearing Housing
  • Motor Feet
  • Base-plate/Foundations
  • Motor Insulation

The importance of including these checks as part of your preventative maintenance plan have been proven by the Cooper Bussmann brand which found that old age was responsible for only 10% of the failure of electric motors.

The most common causes of motor failure are actually:

In addition to regular checks on your motors some early warning signs for motor failure may include:

  • Motors tripping circuit protection
  • Hot motor housing
  • Excess vibration noise
  • Increased operating costs
  • Reduced torque
  • Oil leakage at bearing seals
  • Rust

Ignoring these warning signs may lead to costly repairs and downtime for equipment. Getting a qualified and experienced electrician you can trust in to diagnose these issues is paramount for safety and the lifespan of your motors and equipment.
