Electrical Hazards in Chemical and Pharmaceutical Facilities: Prevention Tips

Friday 17 January

Facilities within the chemical and pharmaceutical industries produce essential and innovative products, ranging from vital chemicals to life-saving medications. Given the nature of these operations, extra attention must be paid to the electrical systems in these buildings, which often handle significant quantities of hazardous substances.

To maintain the safety of your facility, here are 4 electrical hazards to watch for that can lead to catastrophic consequences:

1. Sparking Equipment

The presence of flammable, combustible, or reactive substances poses significant dangers, with even the smallest spark potentially serving as an ignition source. While it may seem like a simple precaution, chemical and pharmaceutical plants frequently make global headlines for fires and explosions that endanger lives and result in substantial fines.

Prevention Tip: Ensure that every piece of equipment is certified for use in hazardous areas, as it will be specially designed to contain or prevent sparks.

2. Environmental Damage

The following environmental factors can negatively impact electrics:

  • Substance build-up from harsh chemicals, moisture and corrosive gases can degrade electrical equipment.
  • Combustible dust can accumulate and settle on electrical equipment.
  • Water and humidity can penetrate electrical systems.
  • Extreme temperatures can damage and corrode equipment.

These factors can lead to short circuits and sparking, which, if not adequately managed, can result in fires and explosions.

Prevention Tip: Regularly consult an accredited electrical engineer to ensure your equipment is in good condition by conducting a hazardous area inspection.


3. Poorly Maintained Electrical Systems

As mentioned, the substances present in chemical and pharmaceutical environments can heighten electrical risks. This is why inadequate maintenance remains a common cause of fires and explosions.

Regulations such as DSEAR and ATEX, enforced by the HSE, require businesses to maintain their electrical systems regularly to ensure the safety of employees and the general public.

Prevention Tip: Set up a maintenance schedule to keep your equipment well-maintained and compliant with industry safety standards.


4. Inadequate Emergency Systems

Emergency systems are vital to safety, serving as mechanisms for fire suppression, swift evacuation and effective incident response. While they may only be needed in emergencies, they play a crucial role in keeping employees safe.

However, a lack of regular testing can cause these systems to fail during a worst-case scenario, potentially escalating dangerous situations.

Prevention tip: Conduct comprehensive risk assessments regularly and ensure emergency systems are frequently tested.


Elevate Your Safety Standards in 2025

One thing all of the above hazards have in common is that they can be prevented through proactive regular maintenance, testing, and inspections.
Safety can sometimes be overlooked in a facility's busy day-to-day operations. However, a trusted electrical engineer can alleviate this burden. At SR Electrical, we offer tailored electrical services designed to meet your facility's unique needs.
