First Aid Only 90671 50-Person ANSI B+ Contractor's Emergency First Aid Kit Review (2026)
Is the First Aid Only 90671 the right kit for a 50-person contractor site that needs a documented ANSI Class B+ fill?
Short answer: Yes — the 90671 is First Aid Only's Class B+ tier kit at 50-person scale, positioned above Class A fills for higher-risk contractor environments. Buyers who don't need the Class B+ documentation should compare the Ever Ready Class B wall-mount kit at a lower price, or the First Aid Only SmartCompliance kit for the same brand at a lower cost without the class fill.
ANSI/ISEA Z308.1-2021 splits workplace first aid fills into Class A (common workplace injuries) and Class B (larger, higher-risk environments). Most of the workplace first aid kits collection skews toward Class A or unclassified OSHA-oriented kits. The First Aid Only 90671 is one of the few 50-person kits on this site to carry an explicit Class B+ designation, First Aid Only's enhanced build on the Class B assortment.
This review checks what that documented higher-risk fill costs against Class A alternatives and against First Aid Only's own 50-person siblings.
Editorial verdict: 4.5/5. The First Aid Only 90671 earns 4.5/5, the highest rating in this batch, for delivering a documented ANSI Class B+ fill at 50-person scale — the higher-risk tier most contractor 50-person kits on this site don't offer. The $85.32 price is the main tradeoff against the cheaper Ever Ready Class B kit.

Pros
- Documented ANSI/ISEA Z308.1 Class B+ fill — higher-risk tier than the Class A fills most competing kits carry
- 50-person rating suits a mid-sized contractor crew or site
- SKU 90671 is printed directly in the title for precise reorder confirmation
- Contractor and emergency-use marketing matches job site conditions
Cons
- Priced above the Ever Ready Class B kit ($59.95) for the same general Class B tier
- Priced below but close to the First Aid Only SmartCompliance kit ($99.73) which doesn't state a class at all
- No SmartTab-style restocking system
- Class B+ fill is overkill for low-risk office environments
Who should buy the First Aid Only 90671 50-Person ANSI B+ Contractor's Emergency First Aid Kit
- Contractor sites and higher-risk work environments that need a documented Class B+ fill
- Safety managers whose program specifically requires ANSI Class B rather than Class A
- Buyers comparing 50-person options across the workplace first aid kits collection
- Sites stepping up from a Class A kit as hazard assessment changes
Strengths of the First Aid Only 90671 50-Person ANSI B+ Contractor's Emergency First Aid Kit
Documented Class B+ fill fills a real gap
Most of the 50-person kits reviewed elsewhere in this collection carry a Class A fill or no stated class at all. The 90671's explicit Class B+ designation gives higher-risk sites a documented option without leaving the First Aid Only brand.
Named SKU supports precise reordering
The 90671 model number is printed directly in the product title, unlike several lower-priced First Aid Only 25-person kits in the same family.
50-person scale matches realistic mid-size sites
That's a proportionate single-station rating for a contractor crew, shop floor, or mid-sized site without needing multiple kits.
Contractor and emergency framing matches the use case
The listing's marketing language targets contractor and emergency-response scenarios directly, consistent with the higher-risk Class B+ fill inside.
Weaknesses to weigh before buying
Priced above the Ever Ready Class B alternative
The Ever Ready Class B wall-mount kit delivers a Class B fill at $59.95, a meaningful $25+ less than the 90671, though in a different (wall-mountable) format.
Close in price to the SmartCompliance kit without SmartTab
The First Aid Only SmartCompliance 50-person kit at $99.73 adds SmartTab restocking reminders, which the 90671 does not include at $85.32.
No restocking-reminder feature
Unlike the SmartCompliance line, there's no automated way to flag which categories are running low.
More fill than a low-risk office needs
A Class B+ fill is built for higher-risk environments; a standard office or retail site is usually better served, and better priced, with a Class A kit.

Class A vs Class B+: matching the fill to your hazard assessment
ANSI/ISEA Z308.1-2021 defines Class A as the fill for common workplace injuries and Class B for larger, higher-risk environments; our OSHA and ANSI Z308.1 requirements reference explains how OSHA 29 CFR 1910.151's adequacy requirement maps onto those classes. The 90671's Class B+ label signals First Aid Only's enhanced build on the base Class B assortment — appropriate for sites whose hazard assessment points above ordinary office-level risk.
Total cost of ownership
The kit is $85.32, once. Restock cadence should match consumption; a $49.95 Urgent First Aid Class B 50-person refill keeps the class-appropriate fill current between formal audits.
Final verdict: 4.5/5
The First Aid Only 90671 earns 4.5/5 as the strongest documented Class B+ option in the First Aid Only 50-person lineup on this site. Buyers who want a Class B fill at a lower price should compare the Ever Ready Class B kit; buyers who want SmartTab reminders instead of a named class should look at the SmartCompliance kit.

First Aid Only 90671 50-Person ANSI B+ Contractor's Emergency First Aid Kit FAQ
What does ANSI Class B+ mean on the First Aid Only 90671?
ANSI/ISEA Z308.1-2021 defines Class B as the fill for larger, higher-risk environments than Class A; the 90671 ships with First Aid Only's Class B+ fill built on that assortment. See our OSHA and ANSI Z308.1 requirements reference for the full decode.
90671 vs Ever Ready Class B — which should you buy?
Both carry a Class B-tier fill; the 90671 is First Aid Only branded at $85.32, while the Ever Ready Class B kit is $59.95 in a wall-mountable format. Choose based on brand preference and format, since both address the same higher-risk fill need.
Is the First Aid Only 90671 OSHA compliant?
OSHA 29 CFR 1910.151 requires adequate supplies rather than certifying named kits; the 90671's documented Class B+ fill gives a strong basis for a higher-risk program. See the full explainer.
How many people does the 90671 cover?
50, as a single-station rating.
90671 vs SmartCompliance 50-person kit — what's the difference?
The 90671 carries a documented Class B+ fill; the SmartCompliance kit adds SmartTab restocking reminders but does not state a specific ANSI class. Price is close ($85.32 vs $99.73).
Does the 90671 include SmartTab reminders?
No — SmartTab is a feature of First Aid Only's SmartCompliance line specifically, not the 90671.
Is Class B+ overkill for a normal office?
Likely yes — Class B fills target higher-risk environments. A standard office is usually better matched to a Class A kit at a lower price.
What refills fit the First Aid Only 90671?
The Urgent First Aid Class B 50-person refill restores a class-matched fill for $49.95.
Does the 90671 have a specific SKU I can search for?
Yes — model 90671 is printed directly in the product title, which simplifies exact reordering.
Is the 90671 better than a 25-person Class A kit for a contractor crew?
It depends on both headcount and hazard level. A 25-person Class A kit fits a small, lower-risk crew; the 90671's 50-person Class B+ fill fits a larger crew or a higher-risk job.
Can the 90671 be wall mounted?
The listing does not describe wall-mount hardware; for a wall-mountable Class B option, see the Ever Ready Class B wall-mount kit.
What should I add alongside the 90671 for full coverage?
Burn dressings from burn care, eye wash from eyewash stations, and a CPR barrier from CPR rescue supplies.
How often should a Class B+ kit be audited?
Monthly or quarterly based on consumption, confirming quantities against the Class B assortment. Restock from the first aid kit refills collection.
Is the 90671 worth $85?
For sites whose hazard assessment calls for Class B, yes — it's the strongest documented option in the First Aid Only 50-person family. If Class A suffices, cheaper options like the First Aid Only 91248 deliver more value.
