Best Management Practices for Cornell Greenhouses (Ithaca)

Best Management Practices for Pesticide Storage

Revised October 20, 2005

Rationale

Greenhouse pesticide storage areas can contain a wide range of concentrated chemicals, some in relatively large quantities. These chemicals must be stored and managed properly to prevent the potential release, through broken, damaged or leaking containers, of chemicals that may have the potential to cause harm to human health and the environment. Some potential problems associated with pesticide storage areas include risk of spills during storage, mixing or loading operations; loss of security; accumulation of unwanted, old, or unregistered materials; and the risk of fire, flooding or some other disastrous event. These problems can be minimized through the proper use of building security, temperature control, fire prevention and suppression equipment, inventory control, secondary containment, emergency mitigation/planning, preventive maintenance, good housekeeping and user education.


Environmental Principle: Greenhouse pesticide storage areas contain relatively large quantities of concentrated chemicals. These chemicals must be stored and managed properly to prevent the possibility for release to and contamination of the environment.
