What is the first step before charging a gas chlorine cylinder in a room?

Starting the exhaust vent fan is a crucial first step before charging a gas chlorine cylinder in a room because it helps ensure the area is ventilated, mitigating the risk of chlorine gas accumulation. Chlorine gas is highly toxic, and even small leaks can pose serious health hazards. By activating the exhaust fan, you facilitate the removal of any chlorine gas that might escape during the operation, thus protecting both the personnel in the vicinity and the overall safety of the environment.

Effective ventilation is essential in managing hazardous gases, ensuring that the atmosphere remains safe for workers and preventing the buildup of harmful concentrations. This proactive measure is a key component in maintaining safety protocols during the handling of chemicals like chlorine.
