2 Bin System

Two identical plastic bins are used alternately. Both bins are filled with supplies. Workers use the first bin until it is emptied. Once the first bin is empty, they start using the second bin.  The empty bin acts as a signal to refill. This way supplies continue to flow without pause.

Cycle Inventory

The inventory a program needs on hand to meet total community demand. It ensures the supplies are available for daily operations.


First In, First Out is an inventory rotation system. Simply, newly arrived inventory is stored to the back and older inventory is moved to the front to be used first.


An educated estimate of future demand based on data and frontline experience. An essential resource to plan future inventory ordering.

Lead Time

Community Agency

May also be referred to as a satellite site, or community partner. Community Agencies obtain harm reduction supplies from their core Needle Syringe Program (NSP).

Core NSP

The organization within a Public Health region responsible for overseeing the coordination, distribution, and ordering of harm reduction supplies. Core NSPs are usually Public Health Units, except in instances where they have contracted out this function to a community agency. The core NSP onboards, trains and monitors community agencies wanting to distribute OHRDPs harm reduction supplies.

Supply Recall

An event where a harm reduction supply needs to be immediately removed from circulation.  OHRDP follows a supply recall process and encourages all core NSPs to have their own internal recall process protocols.

Family Grouping

Storing supplies in families means items with similar characteristics are together. This would mean items that are regularly used together are stored together, such as all inhalation supplies in one area, all injection supplies in another.

Lot Number

A lot number is an identification number given to a particular quantity or lot of supplies from an individual manufacturer.  The lot number is usually found on the outside of packaging. During a supply recall, lot numbers will be utilized.

Reorder Point

A ROP is a particular level at which your inventory needs to be replenished.

Safety Inventory

The extra amount of inventory in a storage area to prevent an out-of-supply situation. It ensures programs will have enough stock should there be a fluctuation in demand or transportation delay.

Medical Distributor

Packing Slip

A document that accompanies supplies being transported from the Medical Distributor to the core NSP.  It includes a complete list of items included in the delivery.


The process of creating a complete set of supplies an individual will need for using drugs. These items are put in a baggie for a service-user to easily obtain all they need. 

Moving Average
