00:00:03.500 --> 00:00:09.075
Heat is linked to an estimated four hundred
and eighty-nine thousand deaths a year,

00:00:08.825 --> 00:00:15.450
and two point four billion of the world's
workers are likely to be exposed to excessive
heat on the job.

00:00:15.200 --> 00:00:20.070
The people most at risk are the least likely
to get a warning they can act on.

00:00:19.820 --> 00:00:23.050
A weather app tells you it's forty-one
degrees.

00:00:22.800 --> 00:00:27.750
HeatShield tells you what to do about it: for
your body, your job,

00:00:27.500 --> 00:00:28.933
and in your own language.

00:00:31.028 --> 00:00:34.066
Here's an outdoor worker in Dubai.

00:00:33.816 --> 00:00:40.691
HeatShield takes the live forecast and
computes the heat index used by the US
National Weather Service:

00:00:40.441 --> 00:00:45.466
the risk right now, when it peaks, and this
person's risky hours.

00:00:45.216 --> 00:00:49.186
Hour by hour, the chart shows where the heat
is heading.

00:00:48.936 --> 00:00:56.211
Then Amazon Bedrock writes a short action plan
in Arabic: three concrete steps and the
warning signs,

00:00:55.961 --> 00:00:59.646
grounded in CDC and NIOSH guidance.

00:00:59.396 --> 00:01:04.546
Two reviewer agents check its language and its
safety before anyone sees it.

00:01:04.296 --> 00:01:08.804
For anyone who finds reading hard, Amazon
Polly reads it aloud.

00:01:16.332 --> 00:01:20.962
Switch the language, and a coworker gets their
own plan in Hindi.

00:01:20.712 --> 00:01:24.123
HeatShield writes plans in thirteen languages.

00:01:27.795 --> 00:01:30.445
Nobody has to remember to check.

00:01:30.195 --> 00:01:39.920
Every hour, EventBridge Scheduler re-scores
everyone, and Amazon SNS emails anyone whose
risk reaches their personal alert level:

00:01:39.670 --> 00:01:44.025
at most once per level each day, and never at
night.

00:01:43.775 --> 00:01:46.150
This is a real inbox.

00:01:45.900 --> 00:01:47.033
The six a.

00:01:46.783 --> 00:01:47.125
m.

00:01:46.875 --> 00:01:50.962
alert was sent by the schedule on its own,
before the heat of the day.

00:01:53.043 --> 00:01:56.273
HeatShield is built for communities.

00:01:56.023 --> 00:02:03.848
A foreman, a teacher or a clinic worker shares
one invite link and watches the whole group on
a private dashboard,

00:02:03.598 --> 00:02:05.673
worst risk first.

00:02:05.423 --> 00:02:10.698
Kai, the coordinator agent, plans who to check
on first and by when,

00:02:10.448 --> 00:02:15.398
across time zones, and for outdoor workers,
the safest eight-hour shift,

00:02:15.148 --> 00:02:16.915
computed from the forecast.

00:02:19.943 --> 00:02:25.793
Behind it are eight AI agents, and you can
watch them work in Agent HQ,

00:02:25.543 --> 00:02:28.193
drawn live from their real runs.

00:02:27.943 --> 00:02:31.753
Each one pairs a real algorithm with a model.

00:02:31.503 --> 00:02:38.215
Sol detects heatwaves against each city's own
climate, and reads fifty-one ensemble
forecasts,

00:02:37.965 --> 00:02:41.073
so a warning says how likely it is.

00:02:40.823 --> 00:02:48.160
Quinn audits the forecast every day: every
missed Danger day and every false alarm is
counted by code,

00:02:47.910 --> 00:02:49.259
not by the model.

00:02:52.509 --> 00:02:57.659
And anyone can ask the team a question, in any
of the thirteen languages.

00:02:57.409 --> 00:03:02.199
Kai assigns it to the right agents, who answer
with their real tools.

00:03:01.949 --> 00:03:08.539
Here, Sol finds Karachi, and Kai searches the
forecast for the crew's safest shift.

00:03:08.289 --> 00:03:12.459
Now a harder one: a coworker showing signs of
heat stroke.

00:03:13.413 --> 00:03:16.943
Nothing a model writes is trusted on its own.

00:03:16.693 --> 00:03:22.343
Code makes the final call: every number in an
answer must come from a tool,

00:03:22.093 --> 00:03:26.968
a health answer that skips the vetted facts is
sent back, and phone numbers,

00:03:26.718 --> 00:03:29.543
medicines and doses are blocked.

00:03:29.293 --> 00:03:33.180
So the answer starts with calling the local
emergency number,

00:03:32.930 --> 00:03:35.863
followed by the vetted first-aid steps.

00:03:35.613 --> 00:03:42.088
Even the model was chosen by measurement: five
Bedrock models answered the same questions,

00:03:41.838 --> 00:03:44.984
and the most accurate one now coordinates the
team.

00:03:47.976 --> 00:03:54.801
It's fully serverless on AWS, in one SAM
template: CloudFront and S3,

00:03:54.551 --> 00:04:01.851
API Gateway and nine Lambda functions,
DynamoDB, EventBridge Scheduler,

00:04:01.601 --> 00:04:09.346
SNS, Polly, Cognito for the operator console,
and Amazon Bedrock behind every agent.

00:04:09.096 --> 00:04:15.071
Failed runs are retried and kept, nine
CloudWatch alarms email the operator,

00:04:14.821 --> 00:04:19.727
and a measured daily AI budget caps the
spending without ever stopping the alerts.

00:04:21.744 --> 00:04:24.994
Even this voice is Amazon Polly.

00:04:24.744 --> 00:04:26.394
It's live right now.

00:04:26.144 --> 00:04:29.978
HeatShield: from forecast to action, in your
language.
