Safe Storage and Handling of Ice Melt Products

Ice Management and De-Icing

Proper storage of de-icing materials extends product effectiveness and prevents the accidental discharge, moisture absorption, and workplace hazards that improper storage creates.

Rock salt stored in open bags or uncovered piles absorbs atmospheric moisture and forms hard clumps that are difficult to spread uniformly. This caking reduces application effectiveness and can jam broadcast spreaders. Store rock salt in sealed containers or a covered storage area with good air circulation.

Best Practices for Ontario Winters

Calcium chloride is particularly hygroscopic — it absorbs moisture rapidly from the air and from contact surfaces. Opened bags of calcium chloride should be sealed immediately after use and stored in airtight containers. Calcium chloride in contact with organic materials (wood, cardboard) can generate heat through moisture absorption.

Chemical compatibility matters for bulk storage areas. Store de-icing chemicals away from fertilizers, fuel storage, and organic materials. Some de-icing products, particularly those containing acetate compounds, are flammable in concentrated form. Review SDS (Safety Data Sheet) information for each product stored.

Professional Snow and Ice Control

Spill containment: all bulk de-icing material storage should be within a containment area or on an impermeable surface to prevent spilled product from running off into adjacent soil or drainage systems. Secondary containment is required under Ontario environmental regulations for significant chemical storage quantities.

Personal protective equipment for de-icing product handling: calcium chloride in particular causes skin and eye irritation on contact. Gloves and eye protection are recommended for frequent handlers. Wash hands thoroughly after contact with any de-icing chemical before touching eyes or mouth.
