4. Precautions and safety suggestions
Although blocking the vent may seem simple, improper operation may cause safety hazards. The following are safety recommendations that have been hotly debated recently:
1.Avoid a complete seal:Many vents have a heat dissipation or pressure relief function, and complete blockage may cause the device to overheat or explode.
2.Consider material temperature resistance:Ventilation holes in high-temperature environments need to use high-temperature-resistant materials. Ordinary tape or plastic may melt.
3.Regular inspection:Temporary plugging solutions need to be inspected regularly to prevent material aging and failure.
4.Professional consultation:For important equipment, it is recommended to consult professionals before operating it.
