First Aid Only or Full Kit? A Buyer's Guide to Stocking Your Worksite (Without Wasting Money)

Let's be real for a minute. I manage the supply ordering for our company—about $80k annually across a handful of vendors. When I took over purchasing in 2020, I thought buying first aid supplies would be the easiest part of the job. Boy, was I wrong.

The thing I've learned after five years of this is: There's no single "right" answer for stocking a worksite. The best setup depends entirely on your situation. So instead of pretending there's a one-size-fits-all solution, I'm going to walk you through the three most common scenarios I've encountered and what actually worked for each.

Here's how I'd break it down:

• Scenario A: Small office or light-duty worksite (under 25 people)
• Scenario B: Medium-sized industrial or construction site (25-150 people)
• Scenario C: Multi-location or high-risk environment (150+ people or specialized hazards)

Your situation might not fit perfectly into one box, and that's fine. The goal here is to give you a framework for making a decision, not a prescription.

Scenario A: The Small Office or Light-Duty Worksite

This is where I started. We had about 40 people in a single office building. No heavy machinery, no welding, just desks and a break room. The First Aid Only brand kit we had was a 25-person basic unit—band-aids, gauze, tape, and some antiseptic wipes.

For this kind of environment, a pre-assembled first aid only kit is actually a solid choice. You don't need a lot of specialized gear because the most common injuries are paper cuts, minor scrapes, and headaches. The key is making sure the kit is compliant with OSHA's requirements for your industry and location.

One thing I learned the hard way: Don't just buy the cheapest kit on Amazon. I did that once. The adhesive on the bandages was terrible—people complained they wouldn't stay on. I ended up replacing it with a First Aid Only brand kit from a reputable distributor. The difference in quality was night and day.

"I'd rather spend 10 minutes explaining options than deal with mismatched expectations later."

My recommendation for this scenario: A 25-50 person first aid only kit from a known brand like First Aid Only. Add a box of nitrile gloves and a small bottle of hand sanitizer. That's it. Don't overcomplicate it.

But here's a twist that surprised me: For small offices, a liquid bandage can be a surprisingly good addition. People with desk jobs tend to get small cuts on their fingers (paper, printer jams, etc.), and a regular band-aid gets in the way of typing. PhysiciansCare first aid only liquid bandage is a great option for that. It's a small tube, lasts a long time, and people appreciate not having to deal with bulky bandages.

Scenario B: The Medium-Sized Industrial Site

This is where things get more complex. I'm not a safety expert, so I can't speak to specific OSHA requirements for every industry. What I can tell you from a procurement perspective is that the needs change dramatically when you move from an office to a warehouse or construction site.

For a site with 50-150 people doing physical work (like at a manufacturing plant or a construction company), a basic first aid only kit isn't enough. You need a more comprehensive setup. The First Aid Only brand makes industrial-grade kits that are well-suited for this.

One thing I've seen repeatedly: People underestimate the volume of supplies they'll go through. In an office, a box of 100 bandages might last months. On an industrial site, you might go through that in a week. So buying a larger kit with refills is a better strategy than getting a small kit and having to reorder constantly.

Also, consider specialty items. For example, burn dressings for welders or heavy-duty gloves for workers handling rough materials. And here's something that surprised me: You might also need supplies that seem unrelated to first aid, like safety fencing to cordon off a hazardous area. It's all interconnected.

For this scenario, I'd recommend:

• A 100-150 person industrial first aid only kit from a brand like First Aid Only
• Refill packs for the most-used items (bandages, gauze, ointment)
• Specialty items based on your specific hazards (burn care, eye wash, splints)
• Consider adding a liquid bandage like PhysiciansCare first aid only liquid bandage for quick fixes on the go

Even after choosing the right kit, I kept second-guessing. What if I missed something? The week until the first inspection was stressful. Then the safety officer gave us a thumbs up, and I relaxed a little.

Scenario C: Multi-Location or High-Risk Environment

This is the scenario I haven't dealt with personally, but I've supported our operations team during a facility expansion. For companies with multiple locations or high-risk operations (like chemical plants or heavy construction), you need a system, not just a kit.

The most frustrating part of managing this kind of setup: The same issues recurring across different sites despite clear communication. You'd think written specs would prevent misunderstandings, but interpretation varies wildly. What one site manager considers "adequate" another considers "insufficient."

In this scenario, I'd recommend a centralized approach. Have a standard kit that goes to every location (like the First Aid Only 300-person industrial kit). Then allow each site to add specialty items based on their specific needs. This creates consistency while allowing flexibility.

Also, consider the logistics of restocking. If you have multiple sites, having a central inventory of refill items is more efficient than having each site order independently. I've seen companies waste thousands of dollars on rush shipping charges this way.

Speaking of waste, let's talk about something unexpected: can you use pepper spray on dogs? This came up when a site manager asked me about it—apparently a stray dog was roaming the construction site and workers were nervous. I'm not a legal expert, so I can't speak to the legality of using pepper spray for animal control. What I can tell you is that if you're considering it for a worksite, you should consult your legal and HR departments first. It's a liability issue. A better solution might be to contact animal control or invest in proper safety fencing to keep animals out.

To sum up this scenario:

• Standardize on a large, comprehensive kit (like First Aid Only industrial)
• Allow site-specific customization
• Centralize inventory and restocking for efficiency
• Address unexpected hazards (like animals) through proper procedures, not improvised solutions

How to Figure Out Which Scenario You're In

Honestly, this is the hardest part. Most people think they're in a simpler scenario than they actually are. Here's a quick decision guide:

Start with headcount: How many people are on site at any given time? This is usually the biggest factor. Under 25? Scenario A. 25-150? Scenario B. Over 150? Scenario C.

Consider the work being done: Are people just sitting at desks, or are they operating heavy machinery? Physical work = higher risk = more supplies needed.

Check your compliance requirements: Your industry may have specific OSHA or ANSI requirements. For example, ANSI Z308.1-2021 specifies minimum requirements for workplace first aid kits. Know what you're required to have before you buy anything.

Don't overthink it: At the end of the day, a first aid only kit from a reputable brand like First Aid Only is almost always a good starting point. You can add to it as needed. The important thing is to start somewhere and adjust based on feedback.

Hit 'confirm' on whatever you decide and immediately think 'did I make the right call?' That's normal. Didn't relax until the supplies arrived and people started using them. But once you see your team actually using the stuff you bought (and not complaining), you'll know you made the right choice.
