Who this is for: hospital, clinic and procurement staff who need to know how a crash cart is locked, what a numbered seal is, and what a lock-check log should record. After reading you should be able to tell a tamper-evident seal from a padlock, read a vendor’s seal specification, and decide which fields your own check log needs. General product information only; it is not medical advice and not a statement of what your facility’s policy or regulator requires.
Purpose and setting
A crash cart lock is normally a tamper-evident seal, not a key lock. Manufacturers describe a “breakaway lock bar” across the drawers, closed with a disposable numbered plastic seal. Pulling the seal breaks it, so the cart opens at once and the broken seal shows that it was opened. The Joint Commission’s Quick Safety Issue 32 (April 2017) lists, among contributing factors in crash-cart safety events, both “unsecured carts or carts that have been tampered with” and “carts secured with heavy duty tape and/or padlocks, preventing immediate access.” The design goal is therefore both at once: show tampering without delaying access in an emergency.
This page covers the lock and seal only. For the cart as a whole, see what a crash cart is; for contents, see the emergency response cart checklist for an outpatient clinic.
Checklist table: lock and seal items
The rows below are what manufacturers and the sources listed at the end of this page describe. None of it comes from a published standard (see “Standards or rules that apply”).
| Item | Quantity guidance | Why | Notes |
|---|---|---|---|
| Breakaway lock bar on the cart | One per cart | Holds the drawers shut until a seal is broken | Harloff A-Series 7-drawer cart MPA3030B07 is listed with a heat-sealed powder-coat breakaway lock bar |
| Numbered breakaway seals | Sold in packs of 100 (Harloff BASEALS-100; AliMed 2970014458); the Harloff cart above ships with 100 | Shows the cart was opened; the number identifies the seal | Harloff seals are yellow, about 2 inches square, with a 7-digit number that Harloff says “can be easily tracked by medical staff for restocking and verifying expiration dates”; once affixed they “cannot be reused” |
| Seal number recorded in the check log | One entry per check | Lets a reviewer match the seal on the cart to the record | The CDCR example below records the seal number on a daily check sheet and an inventory log |
| Sealed tray (alternative to a drawer lock) | Per tray | Seals a tray’s contents and shows the shortest expiry date | Heart of England NHS trust study: items to check fell from 108 to 28 (via Joint Commission Quick Safety 32) |
Worked example: a two-colour seal scheme
California’s prison health system (CDCR Health Care Department Operations Manual 3.5.22, effective 11/2009, revised 05/06/2024, reviewed 02/11/2026) seals a treatment cart with “a red tamper-resistant, numbered seal which must be broken to gain access to the medications.” After the cart is opened, licensed health care staff apply a yellow seal. Only pharmacy staff have access to red numbered seals, and the pharmacist re-seals red after verifying the medications. Nursing records the red seal number on a daily check sheet (form CDCR 7544), and the inventory log kept on the outside of the cart (CDCR 7529) carries the red seal number and pharmacist initials. At the monthly pharmacy inspection the pharmacist checks the integrity of the red seal. This is one correctional system’s policy and is shown as an example of a scheme, not as a general rule.
What varies by facility type
Vendors list breakaway lock bars on crash carts and on pediatric, malignant hyperthermia and MR-Conditional carts (Harloff product page). The sources here describe three arrangements: a drawer-bar seal (vendor carts), a colour-coded two-seal scheme run by pharmacy (CDCR), and sealed trays inside the cart (the NHS trust study). Seal ownership, who may re-seal and how often the log is checked are set by each facility’s own policy; Quick Safety 32 advises identifying “who checks the crash cart and how frequently it is checked (e.g., daily, once per shift, once during hours of operation)” and who restocks.
Storage, expiry and restocking
A seal number is a record of opening, not an expiry date, so a check log usually holds two things: the seal number and the earliest expiry among the contents. Harloff says the seven-digit number on each seal can be “easily tracked by medical staff for restocking and verifying expiration dates.” The sealed-tray label in the NHS study printed the tray’s unique ID, its contents and the shortest expiry date of any item in the tray. Quick Safety 32 also names “carts not checked or inspected according to policy and procedure” as a contributing factor. Harloff describes its seals as disposable and not reusable once affixed.
For related hardware, the medical cart accessories checklist lists numbered breakaway seals alongside other cart parts, and stocking an emergency trauma response kit covers kit contents. Supplies for emergency, trauma and crisis response are listed in one category.
Standards or rules that apply
No ISO, ASTM, NFPA, AHA or CMS standard setting crash-cart lock or seal specifications was found, and no tensile or tamper-test values appear in the Joint Commission, CDCR or vendor material cited here. The Joint Commission document is explicit that it is “not a standard or a Sentinel Event Alert”, so it is guidance, not a requirement. Specification figures on this page (seal size, digit count, colour, pack size) are manufacturer-published product details for those named products, not requirements. Check your own accreditor, state rules and facility policy for what binds you.
FAQ
Is a crash cart locked?
Usually sealed rather than locked: vendors describe a breakaway lock bar and single-use numbered seals that break with a sharp pull. The Joint Commission lists padlocks and heavy-duty tape as factors that prevent immediate access.
Padlock or breakaway seal?
The Joint Commission names padlocks as a contributing factor in safety events because they prevent immediate access. A breakaway seal opens with a pull and cannot be reused, so it shows tampering without a key.
What are crash cart requirements for the lock?
No published standard found sets them. What exists is guidance (Joint Commission Quick Safety 32, 2017) and facility policy such as the CDCR scheme above. For the cart overall, see what a crash cart is.
What are crash cart specifications for seals?
Only product specifications exist: for example Harloff’s seal is yellow, about 2 inches square, 7-digit numbered, pack of 100; AliMed lists a yellow 100-pack for its own carts. These describe those products only.
