The question, in the buyer's words
I run a 150,000-square-foot cold storage warehouse in Little Rock, Arkansas, and our fire marshal wants to know how autonomous forklifts will charge overnight and where the batteries sit before we add them; what should we have ready for that review?
Key takeaways
- The fire review turns on the charging room and battery location, so approve that layout before you choose a robot model.
- Little Rock works from the 2021 International Fire Code with Arkansas amendments, and the state code took effect January 1, 2023.
- An insurer's guidance points to 60 minutes of fire resistance around a designated charging area, a target to confirm rather than settled code.
- Summer highs averaging near 92°F and winter lows near 34°F mean the charging room needs a temperature plan as well as a fire plan.
- Our lease quote follows a free site assessment, and that assessment can include a check of the planned charging room.
What does a Little Rock cold storage fire review ask about forklift charging?
A fire review of autonomous forklift charging in a Little Rock cold storage building asks three things: where the trucks charge, where the spare batteries are kept, and how a fire would be found, contained and reached by responders. Your fire marshal raised these before any install, so the charging layout belongs in the building plan from the start, not in a checklist after the robots arrive.
The battery chemistry decides how hard the review is. An insurer's guidance on lithium-ion powered forklifts recommends a designated charging area separated by a fire-rated compartment, plus a building plan that shows that area to the fire service. Confirm the chemistry with the vendor early, because separation, ventilation and detection questions all follow from it.
Overnight timing adds a second layer. Charging that runs while the building is empty is harder to watch, so the marshal will ask how faults are detected and who receives the alarm in the middle of the night. Those answers shape the room as much as the code does.
Which fire code applies to a Little Rock cold storage building?
Little Rock adopts the 2021 International Fire Code by reference, with Arkansas amendments, according to a city board agenda. That is the local fire code your reviewer will work from. Ask the fire marshal's office which edition and amendments apply to your permit before the drawings are final, because a code cited in an agenda is not always the exact text a reviewer quotes.
The state layer matters too. A Russellville city compilation of adopted state safety codes lists the 2021 Arkansas Fire Prevention Code as effective January 1, 2023. A 2025 Little Rock agenda item amends building and residential provisions of the 2021 Arkansas code. A residential change may not reach a warehouse charging room, but confirm which building sections changed rather than assuming.
Standards may come into the review too. A fire marshal may reference NFPA 1 and NFPA 855 for battery charging and energy storage. The text of neither standard was checked for this page, so ask which edition the city has adopted and read the adopted text rather than a summary of it.

Where should autonomous forklift batteries sit in a cold storage building?
Batteries should sit in a designated charging area separated from the rest of the building, not spread across aisles, docks or freezer rooms. An insurer's guidance recommends a fire-rated compartment that gives at least 60 minutes of fire resistance around the charging area. That figure comes from an insurer document rather than the fire code text, so treat it as a target to confirm with the marshal and your insurer.
The same guidance advises at least 2 metres of clear area around the battery. It is a loss-prevention figure and secondary to the code, but it is easy to design for and hard to enforce later. Keep that space free of racking, pallets and product, because cold storage floors fill quickly and a clear area used for staging will fail the walk-through.
Freezers add a wrinkle. A battery and charger that operate near a freezer room have to work at that temperature, and the cold changes how the equipment behaves. Keep the charging room outside the freezer envelope unless the vendor confirms the operating range and the fire review agrees with the location.
Mark the spare battery storage on the plan as well as the charger locations. The marshal will ask about every place a pack sits, not only where it charges, and spares that sit outside the charging room need their own separation logic. Keeping spares away from the charger line also reduces the number of places a fault could start.
What should the charging plan show the fire marshal?

A complete packet shortens the review. Start with a scaled floor plan that marks the charging room, battery storage, exits, fire lanes, the sprinkler riser and the access route for responders. Mark each charger location and the clear space around each battery position, so the marshal can read the layout without asking for a second drawing.
Add the charger count and power ratings, the battery chemistry, the charge schedule, the ventilation approach and the detection and suppression inside the room. If the room has smoke or heat detection, say which, and show how an alarm reaches a person who can respond at night. A written answer to the alarm question carries more weight than a general statement about safety.
Attach the vendor documents for the battery and charger, including the manufacturer's charging and storage instructions and any equipment certifications. Write the emergency procedure in plain steps for the night supervisor: who isolates power, who calls the fire department and where the shutoff sits. A procedure that names a person and a place is easier to approve than one that says staff will respond.
Expect a follow-up question on the alarm route. If detection goes only to a general phone line, the reviewer will ask who answers it at night. Name the on-call contact and the escalation path in the plan, and test that route before the first charge.
What do OSHA battery charging rules require on the floor?
OSHA's powered industrial truck standard, 29 CFR 1910.178, covers battery charging areas. A compliance summary of the rule says smoking is prohibited in battery charging areas and that precautions must be taken against open flames, sparks and electric arcs. Summaries disagree on which paragraph letter holds the no-smoking rule, so check the latest text on the federal eCFR before you cite it in your packet.
The rule addresses people as well as equipment. Charging areas need clear no-smoking signs, controlled access and a plan for the staff who handle batteries. A robot does not remove those duties. It changes who is in the area and when.
On the floor, a truck can dock and start charging without a driver walking to the charger. A person can notice heat, odor, swelling or a stuck cable and step away from the room. Your plan should name who checks the charging room on each shift, even when the trucks charge themselves.

How does Little Rock's climate change overnight battery charging?
Little Rock is hot in summer and mild in winter, and both matter for a charging room. According to climate averages for 1991 to 2020, the July average high is about 92°F and the January average low is about 34°F. Those are regional averages, not readings from your building, but they show what the room must handle on an ordinary summer week.
Summer heat adds load to the charging room. A room sealed for fire separation can trap heat from chargers, so the ventilation design has to satisfy both the fire rating and the summer temperature. Ask the vendor for the operating temperature range of the chargers and batteries, then compare that range with July room temperatures, not the annual average.
Winter cold matters if the charging area sits near a freezer or an open dock. Equipment often operates within a stated temperature range, and a room that cools overnight can push it outside that range. The outdoor January low is only a starting point, because the freezer side of a cold storage building runs far colder than the outdoors.
Heat load also depends on the charge schedule. Ask the vendor whether the schedule can be adjusted on hot days, because how many units charge and for how long sets the heat in the room. Log room temperature through the first summer and the first winter, and keep the records with the fire file.
Who staffs and maintains the charging operation in cold storage?
Churn in cold storage affects any battery routine. According to the Global Cold Chain Alliance, cold storage turnover averaged 32.6% in 2019. That is older data, but it points to a problem every operations director knows: the person who learned the charging routine this year may not be there next year, so the routine has to live in a written procedure.
The regional build-out is real. A trade publication reported that a temperature-controlled facility in Conway, Arkansas, broke ground with 135,000 square feet of space and 17,650 pallet positions to serve the Little Rock region. Your 150,000 square foot building is close in size, so the same questions about charging rooms and night coverage are worth asking at your site.
Training and service decide whether the routine holds. Name a backup for each night shift, train at least two people on the charger fault steps, and make sure a trained person can respond when a unit faults. Our service plan is backed by regional service engineers in every state we service, so the night supervisor is not the only person who knows what to do.
Staffing also shapes the review. A fire marshal may ask who is on site overnight and how a fault is escalated. If the honest answer is that one person covers the building, the plan needs an on-call tree that names a second person and a responder route.

What happens after the fire review passes?
Once the charging room and battery location are approved, the work moves to deployment. A free site assessment is the first step with us. It maps the building, checks the planned charging room against your fire review notes and shows where the robots can run. The lease quote follows that assessment and sets the terms.
We pick the right robot for the site across manufacturers, lease it through financing, deploy and integrate it, train the staff, and service every unit under our service plan. One partner across that lifecycle means one point of contact when the marshal's conditions and the robot's operating conditions have to match.
Ask for a start that fits the review. Begin with one leased unit and one approved charging room, then add units after the fire marshal and your night staff have seen the routine work. A phased start also builds a record of charging, temperature and alarm events to show the reviewer during the first months.
Keep the review file current after go live. Record any change to the charger count, the battery type or the room layout, and send that change to the fire marshal before it happens. A file kept up to date makes the next change easier to approve.
