Answer :
Final answer:
When ventilating a fuel tank repair area, it's essential to use Explosion-proof air conditioners, designed to prevent the ignition of flammable gases or vapors, ensuring a safe environment. Standard air conditioning units should not be used due to the risk of ignition.The correct answer is C) Explosion-proof air conditioners
Explanation:
The question asks about the type of air conditioners that should be used inside the repair area for ventilating a fuel tank. The correct answer is C) Explosion-proof air conditioners. Ventilating areas with potentially explosive atmospheres, such as fuel tank repair sites, requires using specialized equipment designed to prevent the ignition of flammable gases or vapors.
Explosion-proof air conditioners are specifically designed to operate safely in such hazardous environments. They are constructed to contain any sparks or components that could ignite flammable substances, effectively preventing accidents. Using any other type of air conditioning, such as window or portable units, in these environments, poses a significant risk of ignition and should be strictly avoided.
It is crucial in engineering and safety practices to select equipment that aligns with the specific hazards of the working environment. The understanding and application of these safety measures are integral to the field of safety engineering, a discipline focused on minimizing the risk of accidents and injuries in the workplace.
