Phone lists change every day
Workers and contractors come and go. JSA lets your site communicate without forcing your company to maintain accounts for every contractor.
Communication Built For Real Job Sites
Every site alert. Every worker. Accounted for.
Job Site Alerts gives safety teams one controlled system for job site announcements, stop work reports, stand down notices, bilingual communication, weather status changes, and read confirmation.
Stop managing lists by hand
The old job site contact list is broken.
Safety admins should not spend their day chasing constantly changing phone numbers, contractor rosters, SMS groups, and message screenshots. Job Site Alerts is built for one purpose: reliable communication across active job sites.
Group chats are not compliance systems
Limited SMS lists and general chat tools do not give you read status, site-specific control, or a purpose-built safety workflow.
Weather delays cost real money
Close a site, stand down, or resume work quickly so workers know before they waste a trip and teams avoid preventable site costs.
Safety, status, and recordkeeping
Regulated-site communication without the clutter.
JSA is not a general messaging product. It is designed for safety teams who need clear job site communication, measurable delivery, and fast worker access from iPhone or Android.
Anonymous Stop Work
Every worker has a fast way to submit a stop work message with photos, without exposing identity to the field.
Read Confirmation
Admins can see who has and has not read critical messages instead of relying on guesswork.
English and Spanish
Messages automatically translate between English and Spanish for workers and admins.
Know Who Is Cleared
Track orientations, OSHA training, equipment certifications, and other site requirements in one shared admin view.
Site Status Changes
Configure heat index, wind, lightning, and other worksite alerts per customer and per site.
Stand Down Notices
Tell everyone when work stands down, include instructions, and send a resume notice with one quick action.
See the workflow
Built for the field, not the office fantasy.
Job sites are temporary, messy, multilingual, and full of contractors. The system is simple because the conditions demand it.
- Send announcements to every current worker on the site.
- Close the site for the day before crews arrive unnecessarily.
- Send stand down and resume notices with instructions.
- Let workers join with a phone number. No email required.
- Use one focused system instead of repurposed group chat tools.
iPhone and Android
Scan, install, and get the site connected.
Workers can use the JSA app with only a phone number. Admins can coordinate job site communication without forcing every contractor through company account provisioning.
Simple site pricing
One site. One monthly invoice. No contract.
Job Site Alerts is billed at $700 per site per month by invoice. The fee covers up to 2000 users. When the job is done, stop paying. No long contract is required.
