Why must unwashed containers be locked according to record retention rules?

Unwashed containers must be locked primarily to prevent contamination and ensure safety. When pesticide containers are used, they may still contain residual chemicals that can pose risks to humans, animals, or the environment if mishandled. Locking these containers helps secure hazardous substances and prevents accidental exposure or misuse.

By keeping unwashed containers locked, pest control professionals protect their employees, clients, and the surrounding community from potential dangers posed by remaining residues. It ensures that only trained individuals have access to these materials, significantly minimizing the risk of accidents or unauthorized use. This practice aligns with safety protocols and regulations aimed at promoting responsible pesticide management and safeguarding public health.
