How to Use Less Salt

Limit Hazard Potential 

• Close unneeded areas, (patios, overflow parking and walkways) but do not impede emergency exits, accessibility ramps or entrances. 
• Display health and safety signs to remind staff and visitors of potential hazards. 

Increase Traction  

• Use an ice chipper to remove the ice or at least roughen its surface. 
• Spread sand, small gravel or volcanic mineral.   

Use the Right Amount  

• Spread smaller amounts of deicers. Often people use too much, which is unnecessary. Only 2 TBSP of salt is needed per square meter. 
• If you spill or accidentally use too much salt, clean it up and save for another time.
• Maintain accurate and complete records.  
• Use closed loop electronic controllers rather than manual controlled systems. 

Use Different Methods 

• If more than 1.25 cm of snow has accumulated, you should shovel/plow prior to salting.  
• Use tools, like pavement temperature measurements, to determine timing and rate of salt application.  
• Use pre-wetting/brine application techniques to help salt adhere and prevent snow from bonding to pavement. 

Limit Ice Formation  

• Shovel often and do not let snow or slush accumulate. 
• Direct roof runoff away from paved areas.  
• Pile Snow in a lower area close to a storm sewer.
• Limit drifting snow by using snow fences or landscaping. 
• Fix any potholes and uneven areas to reduce pooling of water.

Consider Salt Alternatives 

• Look for salt-free deicers that do not contain any chlorides, especially sodium chloride. 
• Use acetate-based products. 

Things to Consider When Hiring Winter Maintenance Contractors 

• Hire a contractor that is Smart About Salt certified. 
• Ensure payment is based on the number of snow fall events or per season and not tied to salt usage.
• Require a salt management plan.
