Be it a leading oil and gas industry, oil refineries, chemical plants, LNG plants, or mineral processing industry; it has an explosive environment that increases the risk of ignition.
An area is declared to be hazardous when the environment has flammable particles that can cause disturbance or explosion any moment due to irregularity of temperature or faulty systems. In the electrical industry, hazardous areas do exist due to the combustible elements present in the environment. The risk involved in the industry is due to the dangerous environment and faulty system that can cause flames.
Cases of explosives in a hazardous area
An explosion at an explosives plant in Gladstone, South Australia, on May 9, 2006, killed three people and wounded two others. The explosion, which devastated the plant and levelled almost all within a 100-meter radius, could be seen up to 70 kilometres away.
The industry failed to maintain and install safety measures to avoid combustion in the area.
An explosion at the Apache Energy Varanus Island gas processing facility’s 30-centimetre gas pipeline caused it to rupture and fires to start about 1.30 pm on 3 June 2008. The lack of maintenance and unreliable anti-corrosion coating and cathodic safety scheme on the pipeline led to the explosion in Australia’s Varanus Island.
Importance of designing and installing equipment to prevent combustion in hazardous areas
With the presence of explosive content in the environment of a hazardous area, it creates a requirement to create and maintain explosion protection techniques and prevent the installation of faulty instrumentation or system. The types of machinery must be designed with a proper inspection to assure safety measures and avoid explosion due to the effect of equipment on the ambience.
The key is to perform and function in volatile environments that satisfy the standards, as well as create, evaluate, and inspect electrical equipment. Along with installing and testing secure installations, it is critical to pick equipment and provide a comprehensive construction design for electrical equipment installed in unsafe environments.
Explosion prevention technology, dangerous environment standards and protective controls, equipment and testing methods collection, design criteria, and earthing condition are all required to prevent damage in a risky zone.
Hazardous Area training provided by PMV in Australia to design and install equipment
PMV provides a professional development course for electricians, electrical engineers, and instrument technicians who have a keen interest in developing their skills of designing, installing, maintaining, and inspecting equipment to prevent hazards in the industry.
The course provides the opportunity of installation and inspection of equipment, classification of hazardous area, standards of processing in a hazardous area, breakdown and maintenance of equipment, and testing procedures for protective equipment.
The course includes:
- UEENEEE015B Develop Design Briefs For Electrotechnology Projects or equivalent
- UEENEEM054A Plan Electrical Installations in Hazardous Areas – Gas Atmospheres
- UEENEEM055A Plan Electrical Installations in Hazardous Areas – Dust Atmospheres
- UEENEEM056A Plan electrical installations for hazardous areas – pressurisation
- UEENEEM057A Design Explosion-Protected Electrical Systems and Installations – Gas Atmospheres
- UEENEEM058A Design Explosion-Protected Electrical Systems and Installations – Dust Atmospheres
- UEENEEM059A Design explosion-protected electrical systems and installations – pressurisation
