Where should emissions program stickers be securely stored?

Emissions program stickers should be securely stored in a lock and key location to ensure their integrity and prevent unauthorized access. This practice is essential for maintaining compliance with emissions regulations and preventing potential fraud or misuse of the stickers. Secure storage not only protects the stickers from theft or damage but also reinforces the importance of controlling access to important materials that are integral to the emissions testing process.

A filing cabinet, while it may provide some level of organization, does not offer the enhanced security needed for such sensitive items. Storage on the testing equipment could lead to loss or misuse, and keeping them in a technician's personal office does not provide adequate security, as access could be less restricted. Therefore, the safest and most compliant option is to use a lock and key location, ensuring that the stickers are kept under strict control and oversight.
