Show answer and explanation
Answer: A. Local exhaust ventilation
Local exhaust ventilation captures harmful gases and mists near their source and exhausts them, keeping workers from inhaling them. It removes harmful substances more efficiently than general ventilation of the whole room. Exhausted gas is treated with scrubbers and the like as needed before release to the atmosphere.
