First aid kits must be at hand in case of minor first aid injuries that may occur at the workplace. First aid supplies must be stored in containers to protect their contents from damage, deterioration and/or contamination. Stock should be purchased through a trusted vendor and replenished as needed to maintain minimum quantities. Content must not contain over-the-counter or prescription drugs, as they may fall into the hands of minors, cause allergic reactions or expired drugs. Employees can store and manage their own medications.
