How do I store HCl safely?
This question is related: Handling and storing sodium hydroxide, hydrochloric acid, hydrogen peroxide and isopropyl alcohol 

In the industries the handling of chemicals maybe periodic and, with routine, one tends to forget the hazardous and risks related to this. There's a lot of information on the web (http://water.usgs.gov/admin/memo/policy/wrdpolicy94.006.html):

STORAGE: Hydrochloric acid should be kept in a tightly closed container and
stored in chemical area that is compatible with other chemicals.
Store in a secure, well-ventilated area, that is well marked, and
away from the general work population.  Do not store near oxidizing
materials.

This manual should be helpfull too: http://www.jsia.gr.jp/data/handling_02e.pdf

1. Types of Containers:

If you keep reading the manual there is valuable information about handling, transportation, and rules to keep the human safety.
