FAQ
How do I prove the latency is from the API provider?
Compare the timestamp inside the webhook payload itself against when your server received it. That difference is your total latency. If the payload's timestamp is already old, the delay happened before it was ever sent t...

What happens if a sensor fails calibration during a routine check?
You must have a pre-defined corrective action procedure. This includes assessing the impact on product stored since the last successful check, quarantining that product if necessary, replacing the sensor, and documenting...

What's the acceptable tolerance for cold chain humidity sensors?
Tolerance is dictated by your product's stability requirements, not a generic standard. A ±3% RH drift might be acceptable for some food products but catastrophic for hygroscopic pharmaceuticals. Your procedure has to de...

Can I use salt solutions for calibration in a cold room?
Technically yes, because they create a known relative humidity. Practically, it's very difficult. Achieving a stable humidity point with a salt slurry in a -20°C environment is slow and prone to error. Most professionals...

How often should cold chain humidity sensors be calibrated?
There's no universal timeline. You have to base it on the sensor's criticality and environmental stress. A sensor monitoring a stability chamber for clinical trial material might need quarterly checks, while one in a les...

What types of events should trigger alerts versus being silently logged?
Alerts should be used for true deviations like unauthorized route zones, extended unscheduled stops, or drastic ETA changes. Routine urban traffic, planned driver breaks, or minor GPS drift should be silently logged or i...

How do I get drivers to take alerts seriously again?
Rebuild trust by involving drivers in setting alert rules. If they know an alert only triggers for a genuine, reviewed issue (like a known traffic blackspot), they'll pay attention. Silence the trivial stuff first.

Should I just reduce the number of alerts we send?
Not just reduce—categorize. Create a strict hierarchy. A minor reroute might be a silent log entry, while entering a restricted zone triggers a mandatory driver acknowledgment and manager call.

What's the first sign my fleet has alert fatigue?
Look for high dismissal rates with no follow-up action. If 95% of alerts are closed within seconds and never reviewed, your team has learned they're mostly noise.

What is the 'notification void' mentioned in school bus emergency response?
The 'notification void' refers to the stretch of time between when the SOS alert goes out and when the driver or aide can tell the dispatcher specifically what's wrong. This gap occurs while they're trying to manage a bu...

Can a school bus driver call 911 directly instead of using the SOS button?
Yes, absolutely. In many urgent medical scenarios, calling 911 directly is actually faster. The SOS system is designed for situations when the driver can't safely use a phone, though sometimes protocol mandates using the...

What is the average response time from SOS button press to first responder arrival?
Based on real-world data from transportation departments, there's an average gap of 7 to 12 minutes from button press to first responder on-scene in suburban areas. This varies depending on location and how clear the ini...
