Soda ash is not classified as being flammable, explosive, or toxic and it is categorized as a GRAS (Generally Recognized As Safe) substance for use in foods, by the U.S. Food and Drug Administration (FDA).
Although relatively harmless, there are a number of precautions that should be taken by personnel working with soda ash:
Soda ash is friable, so it tends to break into small dusty particles when under pressure or by abrasion. Dust is commercially undesirable since particle dimension is critically important, particularly in glass manufacture. To limit dust formation, soda ash needs to be moved using handling equipment that minimize grinding during transportation. Ideal handling equipment include:
Less desirable are pneumatic systems or screw conveyors.
Soda ash is not corrosive to steels, but it will readily attack iron and rust. Painted surfaces other than epoxy resins are undesirable. Refractory surfaces such as concrete and brick should be smooth and sound and designed so that handling equipment is unlikely to break off small pieces that can contaminate the soda ash.
Soda ash is mildly hygroscopic. It will absorb atmospheric moisture to form an undesirable crust up to five centimeters thick. To prevent this soda ash should be stored in weather tight warehouses. Such warehouses should not be ventilated or subject to gross changes in the atmosphere.
Silos with a bottom cone of greater than 40 degrees are acceptable, as are flat warehouses.
All soda ash sold by ANSAC, and produced by our two U.S. suppliers, is manufactured in ISO 9001 certified plants.

ANSAC’s Member companies place significant emphasis on high quality standards. Each producer utilizes extensive internal quality control procedures to guarantee a continual high quality product. ANSAC also employs strict procedures to ensure that our customers receive the same high quality product leaving the plants.
The primary responsibility for guaranteeing compliance with product specifications lies with the producers, but periodic sampling is conducted by ANSAC as follows:
All quality complaints are handled through ANSAC’s sales offices. When laboratory analysis is required ANSAC contracts the work out to independent labs or utilizes Member company laboratories.
