Packaging and storage

Inhibited hydrochloric acid is poured into special rubberized tanks of the sender or recipient, rubberized containers, polyethylene barrels with a capacity of 50 dm3 and glass bottles with a capacity of 20 dm3 in accordance with current regulatory documentation.
Glass bottles are packed in boxes of type V-1, number 3-2 according to GOST 18573. Packaging must comply with GOST 26319.

The product may be poured into tanks and containers containing residual hydrochloric acid if analysis of the residue confirms its quality meets the requirements of this standard. Otherwise, the residual hydrochloric acid must be removed and the tank or container rinsed. Barrels and bottles must be dry and clean.

Filling hatches of tanks, containers and barrel plugs must be sealed with rubber or polyethylene gaskets, both when shipped to consumers (filled with acid) and when empty containers are returned to the supplier.

The necks of bottles sealed with ground glass stoppers or screw caps should be wrapped in plastic film and tied with twine.
The level (degree) of filling of tanks, containers, barrels and bottles is calculated taking into account the maximum use of the carrying capacity (capacity) and the volumetric expansion of the product with a possible temperature change along the route.

Inhibited hydrochloric acid is stored in sealed containers of the manufacturer and the consumer, made of materials resistant to hydrochloric acid.

Transportation

1) In accordance with the rules for the transportation of dangerous goods, inhibited hydrochloric acid is transported:

- in bulk in railway tanks ("Rules for the Transportation of Dangerous Goods No. 340", Part 2, Section 41);

- packed in barrels and bottles in boxes - by rail in covered wagons in wagon-size shipments ("Rules for the Transportation of Dangerous Goods No. 340", Part 2, Section 42);

- packed in containers, barrels, bottles - by road and water transport.

2) When shipped in packages, barrels and bottles are placed on flat wooden pallets in accordance with GOST 9557-87 in accordance with the requirements of GOST 21650, GOST 24597 and GOST 26663.

The weight of the package must not exceed the load capacity of the pallet.

In a railway carriage, packages are installed so that the capacity (load capacity) of the carriage is fully utilized.

Product Safety Information

Inhibited hydrochloric acid is a caustic liquid that is chemically stable.
In the air it “smokes” as a result of the release of hydrogen chloride and its attraction to atmospheric moisture, forming an acidic fog.

Metals located in the voltage series to the left of hydrogen (Al, Zn, Fe, Co, Ni, Pb, etc.) displace it from hydrochloric acid, which can lead to the formation of explosive hydrogen-air mixtures.

Safety measures include preventing contact of hydrochloric acid with these metals by using anti-corrosion coatings, purging with nitrogen, and testing the gas phase from equipment and pipelines for explosiveness before carrying out fire work.
