What is IEC 60079? Essential Guide to Safety in Explosive Atmospheres
IEC 60079 is a basic guide to ensure the safety of workers in explosive atmospheres. This standard aims to ensure the safe design and use of equipment and installations in hazardous areas where explosive gases, vapors or dusts are present. It contains specific rules and guidelines to minimize the potential risks that can occur in explosive atmospheres.
The IEC 60079 standard ensures that mechanical, thermal and chemical properties are taken into account as well as electrical equipment. This ensures maximum protection against explosions and the safety of workers. The standard also provides detailed instructions on how to select, install, maintain and repair materials.
While working in explosive atmospheres carries serious risks, these risks can be minimized with the guidance provided by the standard. This standard must be applied correctly to create a safe workplace environment.
Purpose and importance of IEC 60079 Standard
This standard aims to minimize the risk of explosion in industrial installations, thus ensuring the safety of workers and plant.
Given the inherently high risk of explosive atmospheres, IEC 60079 is of great importance. The standard helps prevent serious incidents such as fire or explosion by requiring the use of properly designed and manufactured equipment.
The purpose of this standard is to guarantee the safety not only of the equipment itself but also of the personnel in the work area. Given the potential danger of any equipment coming into contact with explosive gases or dusts, the rigorous application of IEC 60079 is vital.
Risks of explosive atmospheres and safety precautions
The risks of explosive atmospheres can always have serious consequences. Such environments may contain flammable substances such as gases, vapors or dusts and, if appropriate precautions are not taken, explosions can occur. Explosions can result in loss of property, loss of life and environmental damage.
Taking safety precautions is vital. First of all, it is necessary to correctly classify the area so that it is clear which equipment to use. It is also critical to know the ignition points of explosives and take measures to minimize them.
Training of personnel should not be ignored. Knowledge of personnel working in explosive atmospheres increases safety and helps prevent accidents. However, regular maintenance and controls are also of great importance.
Safety requirements as specified in IEC 60079 Standard
Equipment must be designed and tested in accordance with IEC 60079. Each component to be used in explosive atmospheres must be examined in detail and must ensure full compliance with the requirements. It must also undergo specific certification processes.
Factors such as mechanical durability and dust/night protection are also covered by this standard. It is aimed to prevent work accidents by ensuring that the equipment is resistant to combustion hazards.
In addition, the electrical insulation and protection class of the equipment must comply with the requirements specified in the standard. Electrical contacts and connections must not produce sparks that could cause an explosion and these risks must be fully eliminated.
In addition, labeling equipment in a manner appropriate to its intended use is also part of the IEC 60079 standard. These labels are important to ensure that users use the equipment correctly.
Finally, the design and manufacturing processes of the equipment must also comply with the safety requirements specified in the standard. Manufacturers have the necessary requirements to produce equipment that can be used safely and minimize the risk of working in explosive atmospheres.
Equipment used in explosive atmospheres
Equipment used in explosive atmospheres must be designed and manufactured in accordance with safety standards. Risks in explosive atmospheres can be minimized by acting in accordance with the guidelines set by the IEC 60079 standard. In this way, the safety of employees and facilities can be ensured.
Regular maintenance and periodic control of equipment used in explosive environments is also of great importance. Everyone’s awareness of this issue and taking the necessary precautions is one of the factors that will minimize work accidents.
Equipment used in explosive atmospheres can generally be as follows:
- Explosion-proof luminaires: Used in areas where there is a risk of explosion. The body and glass of these luminaires are made of special materials resistant to high pressure and temperature.
- Control panels: They must be explosion-proof. In addition, the elements on the control panels must also be made of explosion-proof material.
- Cabling systems: Specially designed versions of cables to be used in explosive atmospheres. These cables must be able to withstand high temperature and pressure.
- Low voltage equipment: It must be specially designed and explosion-proof. Installation and use of this equipment should also be carried out by specialists.
- Motors and generators: Must be made of materials resistant to high temperatures and pressures. In addition, the operating principles of these equipment should be designed in accordance with the measures taken against the risk of explosion.
- Pressure regulators: Controls pressure changes. This minimizes the risk of explosion.
- Safety valves: Used to reduce pressure and keep it under control. These valves are specially designed against the risk of explosion.
- Insulation materials: The insulation materials for the equipment used are also specially designed. These materials must be resistant to high temperature and pressure.
- Combustion sensors: They work as an alarm system in case an explosion occurs. Thus, the explosion can be prevented and loss of life or serious damage can be avoided.
- Fire extinguishing systems: Fire extinguishing systems to be used in explosive atmospheres must provide explosion protection. In addition, the reliability and effectiveness of these systems should be checked regularly.
The correct selection, installation and periodic maintenance of equipment used in explosive atmospheres is of great importance. Taking the necessary precautions with the support of experts in this field plays a major role in preventing occupational accidents.
