Preventing Stormwater Pollution: Materials Storage and Spill Cleanup

Store and Handle Materials Safely

• Read and follow label or MSDS instructions and local procedures.
• Store materials in original containers or clearly label replacement containers.
• Keep containers closed or sealed except when in use. 
• Maintain all containers and replace those that  leak.
• Inspect all containers regularly.

Best - indoors in sealed containers.
Good - outdoors in sealed containers, within a covered paved area.
Acceptable - outdoors in sealed containers, on an uncovered, paved area.

Spill Trapping Device Recommendations

• Indoors - store barrels on a spill containment base.
• Outdoors - storage areas should be bordered by a curb or berm to contain spills.
• Store materials away from high-traffic areas to prevent accidents that might cause spills or cause spilled material to be spread.

Liquid Spills

• Follow cleanup instructions specified on the MSDS and local procedures. 
• Containing spills:
  • Use a drip pan or an absorbent to collect spills.
  • Use drain mats to cover storm drain inlets.
• Locate the source of the spill and take steps to stop further spillage.
• DO NOT hose the spill into a storm drain.
• Immediately clean up spills using absorbent materials and follow proper disposal procedures.
• Report large spills or spills of hazardous materials to your supervisor or environmental department personnel.

Dry Material Spills

• Cover a powder spill with plastic sheeting to keep it from spreading until the spill can be cleaned up.
• DO NOT hose the spill into a storm drain.
• If usable, place spilled material in original or properly marked container.
• Follow procedures for disposal of spilled material that cannot be used.
