Severe Weather Sentry & Lightning Shield.
Real Life-Safety on South African Sites.
South Africa experiences over 15 lightning strikes per square kilometre every year. When storms hit, manual guesswork and phone tracking apps fail. WeatherGuard continuously monitors your site coordinates in the cloud, halts crane lifts in dangerous winds, and sends instant evacuation alerts directly to workers' WhatsApp with interactive headcount confirmation.
Why Continuous Phone GPS Fails on Real Work Sites
Generic safety software tries to track workers’ personal mobile phones with constant GPS. On real South African construction, mining, and agricultural sites, that approach creates severe failures.
| Safety & Operational Factor | WeatherGuard (Static Site Geofencing + WhatsApp) | Traditional Personal Phone GPS Apps |
|---|---|---|
| Device Battery Life | 100% Preserved. Cloud-evaluated against fixed site coordinates; zero battery drain. | Drains standard field phones in 3 to 5 hours due to continuous background polling. |
| Background OS Execution | 100% Reliable. Dispatched over WhatsApp server infrastructure. | Mobile operating systems throttle or kill background web apps within 30 to 60 seconds of screen lock. |
| Worker Data & Airtime | Zero worker cost. Received on existing WhatsApp without consuming worker airtime bundles. | Burns through prepaid employee mobile data bundles, sparking trade union friction. |
| POPIA & Employee Privacy | Fully Compliant. Monitors employer-owned workplace coordinates, never personal handsets. | Severe legal risk under Section 11/14 of POPIA for off-shift tracking of private devices. |
| Evacuation Verification | Interactive [ Sheltered & Safe ] WhatsApp button with live supervisor headcount bar. | Passive screen popups that workers often ignore or miss while working. |
The 4-Stage Storm Safety Lifecycle
Stopping work too late causes fatalities. Stopping work too long causes unnecessary delays. WeatherGuard automates the entire sequence according to South African national standards.
Advisory Watch
WeatherGuard detects atmospheric electrification and approaching strikes. Early heads-up alerts are sent to Site Supervisors and Safety Officers so crews can plan shelter and prepare to lower ungrounded loads.
Emergency Evacuation
A verified cloud-to-ground strike occurs within 15 km. Automated WhatsApp evacuation directives broadcast immediately to all rostered workers: outdoor operations halt, crane booms lower, and personnel seek shelter.
Active Cooldown
During an active storm, dozens of strikes may hit. WeatherGuard suppresses duplicate panic messages. Each strike within the radius silently resets a mandatory 30-minute consecutive strike-free cooldown clock.
SANS 10313 All-Clear
Once 30 consecutive strike-free minutes pass, WeatherGuard automatically broadcasts the official All-Clear notification via WhatsApp: "Storm has passed. Safe to resume operations."
4 Statutory Environmental Tripwires Monitored 24/7
Under Section 8 of the OHS Act 85 of 1993, employers carry a strict duty of care to provide a safe work environment. WeatherGuard tracks all major environmental risks.
Gale-Force Wind & Crane Lift Safety
Tower cranes and telescopic cranes must cease lifting operations when sustained wind speeds exceed 38 km/h (10.8 m/s), and scaffolding becomes lethal in gusts exceeding 50 km/h. WeatherGuard detects breaches and alerts rigging supervisors to ground suspended loads and release crane slew brakes for mandatory weathervaning.
Flash Floods & Deep Trench Collapse
Torrential downpours (≥ 25 mm/hr) quickly liquefy excavation sidewalls, creating deadly cave-in risks in trenches deeper than 1.5 metres and making opencast haul roads dangerously slick. WeatherGuard sends immediate evacuation directives to civil crews to park heavy machinery and exit excavations.
Thermal Heat Stress Index (WBGT)
Standard thermometers ignore humidity, direct solar radiation, and wind. WeatherGuard computes outdoor Wet Bulb Globe Temperature (WBGT) in real time. When WBGT crosses 31°C to 32.2°C, mandatory work/rest directives dispatch to teams (e.g. 45 minutes of work followed by 15 minutes of shaded hydration).
Cloud-to-Ground Lightning Strikes
Tracks cloud-to-ground strikes within 15 km with sensor-verified peak current (kA) and strike distance. Decouples worker safety from guesswork and ensures no employee is exposed to step potential or direct strikes on steel structures or open fields.
Interactive WhatsApp Evacuation Headcount
Sending an alert is only half the job. Safety managers must know who is actually safe in the shelter. WeatherGuard sends an emergency broadcast with a one-tap button: [ 🏃 I Am Sheltered & Safe ].
Immutable SHA-256 Incident Black Box for Labour Inquests
When severe weather causes an incident on an industrial site, employers face formal inquiries from the Department of Employment and Labour (DEL) or the Mine Health and Safety Inspectorate. Saying "we told the workers to stop" is not enough in court.

Frequently Asked Questions
Do workers need a special weather app or data bundles?
No. WeatherGuard alerts and headcount confirmations run over standard WhatsApp. Workers do not need to download additional apps, log into portals, or burn through mobile airtime bundles.
Can I turn off monitoring when a construction site closes?
Yes. WeatherGuard licenses are assigned per monitored site per month. When a project finishes or is placed on hold, you can reassign the license to another active site or cancel it in your billing settings.
How does WeatherGuard support Department of Labour inquiries?
WeatherGuard automatically compiles an Incident Black Box containing sensor coordinates, millisecond WhatsApp delivery receipts, interactive headcount timestamps, and a SHA-256 cryptographic seal. Safety officers can export an official A4 Evacuation Certificate PDF with one click.
What is required to get started with OmniSafe?
To get started, all you need is 1 Compliance Admin license for R1,000 / month. With that single license, you gain 100% access to all features, including the AI Form Builder, employee hub, and safety files. Additional employee seats (R500 field worker, R750 supervisor) and WeatherGuard site licenses (R1,000/site/mo) can be added flexibly over time as you roll out across your company.
