Why is ventilation important during tank cleaning?

Ventilation is a critical aspect of tank cleaning primarily because it serves to eliminate the buildup of flammable vapors. During the cleaning process, residues and remains of the previously stored cargo can produce volatile organic compounds (VOCs) and other gases that may ignite under the right conditions. Proper ventilation helps to disperse these vapors into the atmosphere, significantly reducing the risk of fire or explosion.

Ensuring adequate ventilation enhances safety for personnel involved in the tank cleaning operations and mitigates the hazards associated with flammable conditions. By maintaining a flow of fresh air, the concentration of these vapors is kept well below dangerous levels, thereby creating a safer working environment.
