The invention belongs to the technical field of hydrochloric acid transportation and particularly relates to a hydrochloric acid safety transportation method. The method comprises the following stepsof cooling hydrochloric acid to 0 DEG C-10 DEG C to enable the hydrochloric acid not to be volatilized easily; filling the cooled hydrochloric acid into a hydrochloric acid storage tank for storage; sleeving the hydrochloric acid storage containing hydrochloric acid with a bag with a slaked lime layer; transporting the hydrochloric acid storage tank through a special hydrochloric acid transport vehicle and spraying a hydrochloric acid corrosion inhibitor to a carriage of the hydrochloric acid transport vehicle; arranging a graphite modified polypropylene falling-film absorber in the hydrochloric acid transport vehicle to absorb volatilized hydrogen chloride gas; paving a floor of the carriage of the hydrochloric acid transport vehicle with ice blocks to lower the temperature and arrangingan air conditioner in the carriage used for slowing down melting of the ice blocks through cold air. Through the hydrochloric acid safety transportation method, volatilization of hydrochloric acid canbe effectively inhibited in the transportation process, the volatilized hydrogen chloride gas is fully absorbed, the hazard caused by overflowing hydrogen chloride gas is reduced, and the transportation safety of hydrochloric acid is improved.
