It is crucial to protect the explosion-proof surface of the explosion-proof electric hoist when disassembling it, as this directly affects the explosion-proof performance of the equipment and the safety of subsequent use. Here are some key steps and precautions to ensure the protection of explosion-proof surfaces during disassembly:

1、 Preliminary preparation

Cut off power supply: The primary task before disassembling any electrical equipment is to cut off the power supply to avoid the risk of electric shock and possible explosion caused by electric sparks.

Safety assessment: Conduct a comprehensive safety assessment of the dismantling site to ensure a safe and reliable working environment, free from flammable and explosive substances and potential sources of fire.

Personal protection: Wear appropriate personal protective equipment such as explosion-proof clothing, safety helmets, protective goggles, anti-static shoes, and gloves to reduce the risk of personal injury.

2、 Explosion proof surface protection during disassembly process

Follow the original factory regulations: The disassembly of explosion-proof electric hoists should be carried out in accordance with the original factory regulations and instructions to ensure that every step of the operation meets safety requirements.

Use explosion-proof tools: During the disassembly process, explosion-proof tools should be used to avoid using non explosion-proof tools that may generate sparks.

Avoid scratching and collision: During disassembly and handling, special attention should be paid to avoiding scratching and collision of explosion-proof surfaces to prevent damage to explosion-proof coatings or structures.

Properly store components: Disassembled components should be properly stored to avoid loss or damage. For explosion-proof components, special attention should be paid to their storage environment to avoid moisture, corrosion, or contamination.

3、 Special precautions

Inspection of explosion-proof coating: Before and during disassembly, the explosion-proof coating should be inspected to ensure that it is intact and undamaged. If coating peeling or damage is found, it should be repaired or replaced in a timely manner.

Protection of electrical components: When disassembling electrical components, special attention should be paid to preventing damage or the generation of electrical sparks. For electrical connections, insulation tape or insulation sleeves should be used for wrapping and protection.

Anti static measures: As explosion-proof electric hoists are usually used in flammable and explosive environments, special attention should be paid to anti-static measures during disassembly. For example, using anti-static tools, wearing anti-static clothing, etc.

Emergency response: In the process of dismantling, if there is an emergency situation (such as fire, explosion, etc.), the operation should be stopped immediately and corresponding emergency measures should be taken. At the same time, it should be ensured that all personnel can quickly evacuate to a safe area.
