The term “intrinsically safe” describes a protection technique that limits the electrical and/or thermal energy of electrical equipment used in potentially explosive areas such that there is insufficient energy to ignite hazardous gases or dust. Intrinsically safe equipment is designed to prevent the ignition of flammable gases or vapours by limiting the amount of electrical energy that can be released.
The INTRINSIC SAFETY (IS) protection technique is used for electrical equipment which is installed in hazardous areas by limiting the ELECTRICAL and THERMAL ENERGY outflow.
It is usually applied to equipment and wiring which is incapable of releasing sufficient electrical or thermal energy under normal or abnormal conditions to cause ignition in a hazardous environment. IS is a low-energy technique where the CURRENT, VOLTAGE, and POWER are reduced to a level too low to cause ignition.
Intrinsically safe equipment is essential on tanker ships to ensure the safety of the crew and the ship. It is critical to prevent fires and explosions, which can be caused by the presence of flammable gases or liquids and the use of electrical equipment. By using intrinsically safe equipment, tanker ships can operate safely and reduce the risk of accidents.
