How Often Should First Aid Kits Be Inspected and Restocked?

A first aid kit can look fully stocked from the outside while being unprepared for an actual emergency.

Bandages get used and never replaced. Sterile packages become damaged. Eyewash bottles expire. Adhesives deteriorate. Gloves disappear. Employees may borrow common items without reporting that the cabinet is running low.

The problem often remains invisible until someone needs first aid.

Regular inspection and restocking are therefore essential parts of workplace emergency preparedness. Employers need a practical system for checking quantities, expiration dates, packaging condition, accessibility, and whether the kit still reflects the hazards and size of the workforce.

For most workplaces, a useful best practice is straightforward: inspect first aid kits at least monthly and again whenever supplies are used following an incident.

The exact schedule may need to be more frequent in high-use, high-hazard, outdoor, mobile, or multi-shift operations.

What Does OSHA Require for Workplace First Aid Kits?

OSHA does not establish one universal inspection interval for every first aid kit in general industry.

Under 29 CFR 1910.151, employers must ensure that adequate first aid supplies are readily available when required.

The emphasis is on readiness.

A kit that technically contains the correct products but has missing, contaminated, expired, inaccessible, or unusable supplies may not provide meaningful emergency support.

OSHA Requires Adequate and Readily Available Supplies

29 CFR 1910.151(b) states that adequate first aid supplies must be readily available.

OSHA’s nonmandatory Appendix A explains that the appropriate contents depend partly on workplace size and conditions. Larger operations, multiple operations at one location, or workplaces with unique hazards may require additional kits, greater quantities, or different types of supplies.

This means employers should not simply purchase a generic kit once and assume the obligation has been permanently satisfied.

The workplace should periodically evaluate whether the kit remains adequate.

OSHA Does Not Mandate ANSI Z308.1 for General Industry

OSHA frequently points employers toward the ANSI/ISEA first aid kit standard as useful guidance, but OSHA has clarified that ANSI Z308.1 has not itself been adopted as a mandatory OSHA standard for general-industry first aid kit contents.

That distinction matters.

ANSI/ISEA provides a widely accepted framework for selecting and maintaining workplace first aid supplies, while OSHA establishes the legal obligation to maintain adequate and readily available supplies.

How Often Should a First Aid Kit Be Inspected?

For most workplaces, monthly inspection is a strong baseline.

ISEA recommends that workplace first aid kits be inspected at least monthly or after a first aid incident when products have been used.

That frequency allows employers to identify shortages and deteriorating supplies before they become emergency-response problems.

Inspect at Least Monthly

A monthly inspection works well for many offices, manufacturing facilities, warehouses, distribution centers, and industrial workplaces.

During the inspection, verify that required items are present, usable, within applicable expiration dates, and stored in serviceable condition.

The inspection does not have to become a lengthy administrative process.

With a clearly organized cabinet and reliable inventory system, a responsible employee can often identify missing or expiring products quickly.

Inspect Immediately After Supplies Are Used

Do not wait until the next monthly inspection after an injury.

If employees use bandages, gauze, burn dressings, gloves, eyewash, cold packs, bleeding-control supplies, or another first aid item, the kit should be reviewed and replenished promptly.

This is particularly important for supplies kept in minimum quantities.

A kit may remain apparently well stocked while no longer containing enough of one critical item for another emergency.

High-Use Workplaces May Need Weekly Checks

A manufacturing facility where first aid products are used frequently may need a shorter inspection cycle.

Weekly checks can make sense where minor cuts, abrasions, burns, or similar first aid events occur regularly.

The same may apply to distribution centers, construction operations, maintenance facilities, food processing environments, and high-headcount workplaces.

Inspection frequency should reflect actual consumption rather than an arbitrary calendar.

Some Kits May Need Daily Visual Checks

Certain first aid stations may justify a quick visual check at the beginning of each shift or workday.

This can be appropriate in especially hazardous operations, remote locations, temporary jobsites, mobile crews, or environments where employees frequently access supplies.

A daily visual check does not necessarily replace the detailed monthly inspection.

Instead, it confirms that the kit remains present, accessible, sealed or organized appropriately, and obviously stocked.

Some OSHA Standards Have More Specific Inspection Rules

Employers should also determine whether an industry-specific OSHA rule applies.

For example, OSHA’s electric power generation, transmission, and distribution requirements call for first aid kit contents in vehicles or facilities to be inspected at least annually to ensure required supplies are present and usable.

Shipyard rules require employers to inspect supplies at sufficient intervals to ensure that they remain adequate and serviceable and to replenish them as necessary.

These examples reinforce why employers should identify the exact standard applying to their industry rather than relying solely on a generic first aid checklist.

What Is the Current ANSI First Aid Kit Standard?

The current published standard is ANSI/ISEA Z308.1-2021, American National Standard – Minimum Requirements for Workplace First Aid Kits and Supplies.

The standard establishes minimum performance requirements for first aid kits and organizes kits according to the complexity and hazard level of the work environment.

A new revision entered public review in 2026, but that draft has not replaced ANSI/ISEA Z308.1-2021 as the current published edition.

Class A and Class B Kits

ANSI/ISEA Z308.1 maintains two primary kit classifications.

Class A kits are intended for common workplace injuries where the environment generally presents lower hazards.

Class B kits are intended for workplaces where more complex or higher-risk injuries may occur and therefore require broader quantities and types of supplies.

The correct class should come from the workplace hazard assessment—not simply from the number of employees.

What Should Be Checked During Every Inspection?

Opening the cabinet and confirming that supplies are visible is not enough.

A useful inspection should answer several questions.

Are All Required Items Present?

Compare actual inventory with the workplace’s established first aid checklist.

Look for frequently consumed products such as adhesive bandages, gauze, antiseptic products, gloves, wound dressings, burn supplies, eyewash, and other required items.

If the kit follows ANSI/ISEA Z308.1, verify that applicable minimum contents remain present.

Then confirm that additional workplace-specific supplies are also available.

Are Quantities Still Adequate?

A partially used box may technically still contain supplies while no longer meeting the facility’s operational need.

Consider how many employees the kit serves and how quickly particular products are consumed.

A site with multiple shifts or hundreds of employees may need considerably more inventory than the minimum quantity suitable for a small workplace.

Have Any Products Expired?

Expiration dates require careful attention.

Some first aid products, medications, antiseptics, eyewash solutions, burn products, cold packs, and other consumables may have manufacturer-assigned expiration dates.

Replace products according to those dates and manufacturer instructions.

Do not assume an unopened item remains suitable indefinitely.

Is the Packaging Intact?

Sterile supplies depend on intact packaging.

Replace items when packaging is torn, punctured, wet, dirty, opened, or otherwise compromised.

A product can become unusable well before its printed expiration date if storage conditions damage the package.

Is the Equipment Still Functional?

Not everything in a first aid cabinet expires.

Scissors, tweezers, CPR barriers, flashlights, thermometers, emergency blankets, or other equipment may fail because of physical damage or deterioration.

Inspect these items for functionality and condition rather than looking only for a date.

Inspect the Cabinet Itself

The container deserves attention too.

First aid supplies should be protected from contamination and deterioration.

Look for water intrusion, dirt, corrosion, damaged hinges, broken doors, missing labels, or shelves that no longer hold products securely.

A well-maintained cabinet should help employees identify and reach supplies quickly.

ISEA also recommends regularly disinfecting cabinet surfaces as part of first aid kit maintenance.

First Aid Supplies Should Be Readily Accessible

A perfectly maintained kit provides little value when employees cannot reach it during an emergency.

OSHA has explained that “readily available” is connected to the ability of first aid responders to access supplies quickly enough to provide effective aid.

Avoid Locked or Obstructed Locations

First aid kits should not be buried behind stored material or kept in an area that employees cannot access during normal operations.

If a cabinet is locked for inventory control, access procedures must not create emergency delays.

Consider Facility Size

One centrally located kit may work for a small office.

A large manufacturing facility, warehouse, campus, or multi-building operation may need several first aid stations.

OSHA Appendix A specifically advises larger or multiple operations to consider additional kits, equipment, and quantities.

Remember Mobile Employees

Drivers, utility crews, maintenance teams, service technicians, and remote workers may need first aid supplies in vehicles or mobile work areas.

Those kits also require inspection and restocking.

Vehicle temperature, vibration, moisture, and sunlight can accelerate deterioration, making inspection particularly important.

Restock Supplies Immediately After Use

Restocking should not be delayed until a product reaches zero.

If one first aid incident consumes several pieces of gauze, gloves, or wound dressings, replenish them before another incident occurs.

For critical or high-use supplies, establish reorder thresholds above the absolute minimum.

This creates a buffer between identifying the shortage and receiving the replacement.

Do Not Restock Based Only on Minimum Quantities

ANSI minimum contents are a starting point—not necessarily a complete answer for every workplace.

ISEA advises employers to conduct a workplace hazard assessment and add supplies when necessary based on anticipated hazards and injuries.

A machine shop may need additional wound-care and bleeding-control products.

A facility handling hot materials may need stronger burn-response capability.

Chemical operations may require emergency eyewash and other treatment supplies depending on exposure.

The kit should reflect the workplace.

Use Incident History to Improve Stock Levels

Inspection records become more valuable when they are compared with actual first aid usage.

If adhesive bandages disappear every week, increase their stocking quantity.

If burn dressings are repeatedly used in one department, determine whether the quantity should increase—and whether the recurring injuries indicate a hazard-control problem.

First aid consumption can provide useful safety information.

Products that disappear unusually quickly may point toward a workplace condition that should be investigated rather than simply restocked.

Track Expiration Dates Before They Become a Problem

Waiting until inspection day to read every expiration date is inefficient.

A better system tracks products approaching expiration.

Use Advance Replacement Windows

Organizations can flag products several months before their expiration dates.

This provides enough time to order replacements without rush shipping or temporary shortages.

Rotate Inventory

Where appropriate, use older suitable stock before newly received products.

This can reduce waste while maintaining emergency readiness.

Never rotate expired or compromised products back into service.

Update Records When New Stock Arrives

When replacement items are added, record their new expiration dates.

Otherwise, the inventory sheet quickly becomes inaccurate.

SmartCompliance Can Simplify Kit Maintenance

Large facilities may manage dozens or hundreds of individual products across multiple first aid cabinets.

Manual inventory becomes difficult as the number of locations increases.

Arbill’s First Aid SmartCompliance solution is designed to make missing or depleted supplies easier to identify and streamline replenishment.

An organized cabinet system can reduce the time required to determine what has been used and what needs replacement.

That visibility is especially helpful when several employees access the same cabinet.

Make First Aid Supplies Match Your Workplace

Preassembled kits are useful, but employers should still assess whether the contents fit their hazards.

Arbill’s first aid, emergency, and personal care supplies provide options for building or supplementing workplace emergency supplies according to operational needs.

The goal should not be to maximize the number of items in the cabinet.

It should be to maintain the right supplies, in adequate quantities, where employees can access them quickly.

Who Should Inspect First Aid Kits?

Assign responsibility rather than assuming somebody will notice a shortage.

A specific employee, safety coordinator, supervisor, facility manager, or first aid responder can be assigned to inspect each location.

For facilities with many kits, assign responsibility by department or physical area.

The person performing the inspection should understand the checklist, target quantities, expiration-date rules, restocking process, and how to report a problem.

Backup personnel should also be identified so inspections continue during vacations or absences.

Should First Aid Inspections Be Documented?

For many general-industry workplaces, OSHA does not prescribe a specific monthly first aid kit inspection record.

Documentation is still a valuable best practice.

A simple record can show:

• Inspection date
• Kit or cabinet location
• Inspector
• Missing or damaged products
• Expiring products
• Items ordered
• Date restocking was completed

This creates accountability and makes recurring shortages easier to identify.

Digital systems can simplify this process for multiple facilities.

What Should Trigger an Immediate Inspection?

Do not wait for the normal monthly schedule when circumstances indicate that the kit may no longer be ready.

Inspect it promptly after a first aid incident, after several employees use supplies, after the cabinet is relocated, after water or environmental damage, or when an employee reports that something is missing.

An inspection should also follow significant workforce, process, or hazard changes.

If a facility adds a new production line, chemical process, welding operation, or remote work area, the existing first aid configuration may no longer be sufficient.

Storage Conditions Affect Restocking Frequency

A first aid supply can deteriorate even when nobody uses it.

Heat

Extreme heat can damage adhesives, liquids, medications, or packaging.

Vehicle kits and outdoor cabinets deserve extra attention.

Moisture

Humidity and water intrusion can damage sterile packaging and cause equipment corrosion.

Dirt and Industrial Contamination

Dust, oils, chemicals, and other industrial contaminants can compromise supplies when cabinets are poorly sealed or left open.

Direct Sunlight

Some products may deteriorate faster with prolonged sunlight exposure.

Follow manufacturer storage requirements whenever specified.

First Aid Kit Inspection vs. Workplace First Aid Assessment

These are related but different activities.

A kit inspection asks whether the existing supplies are present, usable, and adequately stocked.

A broader first aid assessment asks whether the right kit, quantities, locations, responders, and emergency capabilities exist for the workplace in the first place.

Both are necessary.

A perfectly stocked Class A cabinet may still be inadequate if the workplace hazards justify a Class B kit or additional specialized supplies.

Do Not Forget Eyewash Requirements

A first aid kit should not be treated as a substitute for emergency eyewash or drenching equipment.

OSHA 1910.151(c) requires suitable quick-drenching or flushing facilities within the work area where employees may be exposed to injurious corrosive materials.

A small eyewash bottle stored in a cabinet may be useful in some circumstances, but it does not automatically satisfy requirements for emergency flushing facilities where the standard applies.

The hazard assessment should determine what is required.

When Should You Restock a Workplace First Aid Kit?

The shortest answer is:

Restock immediately when supplies are used, missing, damaged, contaminated, expired, or below the quantity your workplace requires.

Do not wait for a scheduled reorder cycle when readiness has already been compromised.

For products approaching expiration, replace them early enough that there is no gap in coverage.

A Practical Inspection Schedule

A simple program can work well for many facilities:

After every incident: Check the affected first aid kit and replace used supplies immediately.

Monthly: Complete a full inventory and condition inspection.

Periodically throughout the year: Review usage trends, locations, and whether stocking quantities remain appropriate.

Whenever operations change: Reassess the supplies needed based on new employees, hazards, equipment, or processes.

Annually: Review the overall first aid program and determine whether kit class, locations, quantities, or specialized supplies should change.

This approach combines day-to-day readiness with longer-term program improvement.

Common First Aid Kit Maintenance Mistakes

One common mistake is relying only on expiration dates.

A sterile item with damaged packaging should be replaced even when its expiration date is years away.

Another mistake is waiting until supplies are completely depleted before ordering replacements.

Facilities also sometimes keep one kit for a large or geographically spread-out workforce when employees cannot access it quickly.

Another weakness is blindly maintaining the manufacturer’s original contents without adjusting for actual injury patterns or workplace hazards.

Finally, employers may regularly inspect a cabinet but fail to assign anyone responsibility for completing the reorder.

An identified shortage is still a shortage until the replacement reaches the kit.

Create a Simple Inspection Checklist

A useful inspection does not need to be complicated.

Confirm that the cabinet is accessible and clearly identified. Compare quantities against required stocking levels. Inspect packaging and physical condition. Review applicable expiration dates. Test reusable equipment where appropriate. Remove damaged or expired products. Record shortages and place replacement orders.

Before completing the inspection, verify that critical items are actually available rather than simply marking the checklist because an order has been submitted.

Conclusion

First aid kits should never be treated as set-it-and-forget-it equipment.

OSHA requires adequate first aid supplies to be readily available, but its general-industry rule does not establish one universal inspection interval for every workplace.

For most employers, at least monthly inspection is a practical industry best practice, consistent with ISEA guidance. Kits should also be reviewed immediately after first aid supplies are used.

Higher-use or higher-hazard workplaces may need weekly or even daily visual checks.

During every detailed inspection, verify quantities, expiration dates, packaging integrity, equipment condition, accessibility, and whether the contents still match workplace hazards.

Restocking should occur immediately whenever supplies fall below required levels.

The most reliable first aid programs combine regular inspection, clear employee responsibility, documented inventory, hazard-based supply selection, and an efficient replenishment process.

When that system is maintained consistently, the first time an employer discovers a missing first aid product will not be during an emergency.
