Overhaul coming up? Rent it. Don’t buy it.
If you only need additional gas detectors for your annual overhaul, shutdown, or turnaround, why invest in equipment that may sit unused the rest of the year?
Apollo Safety provides fully calibrated, job-ready gas detector rentals when you need them—and you return them when the job is done.

Always remember

When was the last time your gas detectors were calibrated?

Gas detectors are often the only warning before workers are exposed to hazardous atmospheres.

Routine calibration helps verify that the instrument is performing as expected when it matters most.

It's a simple question—but an important one.

Quarterly Calibration: The Best Practice for Gas Detectors Discover why quarterly calibration is the minimum best practice for gas detectors. Reduce drift, ensure OSHA compliance, and improve safety reliability.

Bump Test vs. Calibration

A bump test tells you a detector responds.

Calibration tells you it's accurate.

Both are essential—but they serve different purposes.

Understanding the difference can improve worker safety, reduce risk, and help maintain confidence in your gas detection program.

Apollo Safety's latest technical white paper explains why both should be part of every safety program.

Invisible doesn't mean safe.

A gas detector that powers on isn't necessarily a gas detector that's accurate.

Over time, sensors can drift due to normal aging, environmental conditions, and exposure to contaminants. That's why routine bump testing and periodic calibration are critical components of any gas detection program.

Reliable gas detection starts with reliable maintenance.

One of the most common questions we get:

"Do I really need to calibrate my detector that often?"

Our answer is simple.

How often do you want to verify that the instrument protecting your employees is actually reading correctly?

Gas detectors don't usually fail overnight.

They drift.

Little by little.

Month after month.

Most people never notice it until the detector is tested.

That's exactly why Apollo Safety recommends quarterly calibration.

It's a simple practice that helps ensure your detector is giving you the most accurate information possible when it matters most.

Because guessing isn't a safety strategy.

How Critical is Your Air?
Testing and calibrating your gas detectors before every use could mean the difference between life and death.
Many gas detection users only want to hear what they want to hear, but those serious about the health and safety of themselves and those they are responsible for wanting the facts.
The facts are that you don’t know that you air is safe by simply turning the gas detector on then going straight to work. The sensors must be tested. Is this news to anyone? No it’s not…or at least it shouldn’t be. All gas detection manufacturers clearly state, in their operational and maintenance manuals, that you must test the detector prior to each critical use.
How Critical is Your Air?
Some manufacturers state that the period between calibrations can be as long as six months (not U.S. manufacturers), in an effort to gain market share because they think it’s what we want to hear. Right.
Standard Questions
How often do I have to calibrate?
Answer: When “field” or “bump” testing indicates the sensors do not reach a high percentage of the “bump” gas value on the can, assuming the gas is within manufacturers “good by” date.
How often must I “bump” test then?
Answer: Before each critical use! If you do not use the meter for at least four weeks you are best served by, at the very least, “bump” testing to verify that the sensor have not croaked, as oxygen sensors can do. You also need to make sure that some eager previous user, looking to see the combustible sensor respond, has not applied his disposable lighter to the LEL sensor and voila…the LEL is either dead from over-ranging or has been poisoned. Poisoned by butane gas? That’s correct. The LEL sensor is looking for Lower Explosive Levels which are approximately in the 0-5% range, not 100%, which is what comes out of that disposable lighter. So how critical is your air and more importantly, how can you verify the safety and accuracy of your air? It’s simple. Make sure you “bump” test before each use and calibrate regularly, which, by the way, will assist in keeping the sensors “healthy.” Some sensors have the tendency to “go to sleep.” Regular calibration schedules not only keep your sensors healthy and verified, but it’s the law. OSHA’s confined space rule 20CFR 1901.146 recommends you follow the manufacturer’s calibration and maintenance schedule, all of which recommend “field” or “bump” testing at regular intervals.
It’s a Simple Procedure
I know you’re thinking this expensive and time consuming. After all, you need a Ph.D. to do this stuff don’t you? On the contrary, with today’s technology, the advent of advanced gas detectors, and the low cost of standard calibration gases (approximately $250-$300 per year) you can have the user doing the “bump” testing on a regular basis and keeping a log of their testing. When the “bump” test indicates a response less than 90% of the target gas in the bottle, you simply proceed with calibration, using the same bottle.
All of this takes, with the newer technology available today, about 3-5 minutes. No kidding, it’s that easy and you have given the user a level of confidence which is not conveyed when you hand them a detector that already has a calibration sticker on it from a calibration they didn’t perform.
So, how critical is your air?

🚨 PUBLIC SAFETY ALERT — Winter Storm Safety Reminder ❄️

A community in Rhode Island is mourning the loss of a young college student who died from carbon monoxide (CO) poisoning while trying to charge his phone in his snow-covered car during this week’s historic snowstorm. Snow obstructed the vehicle’s exhaust, allowing deadly gas to build up inside — and tragically, he didn’t make it.
https://weather.com/news/news/2026-02-26-rhode-island-snowstorm-death-carbon-monoxide
Carbon monoxide is a colorless, odorless “silent killer” that can strike without warning — especially during heavy snowfall and power outages.

📌 Life-Saving Tips:
❄️ Never run a car with the engine on in an enclosed or snow-buried space.
🔥 Keep exhaust pipes, vents, and chimneys clear of snow and ice.
📟 Install and test carbon monoxide detectors in your home.
⚡ Use portable generators only outdoors, at least 20 ft from your house.

Your safety matters — don’t let carbon monoxide become the unseen danger in your winter storm plans. Please share this with friends and family. ❤️
