The Administration for Children's Services is getting a technology upgrade to increase safety.
One new feature is an application on workers' phones that gives child protective specialists a direct line to 911.
Dispatchers will automatically know their location, and will intervene if a dangerous situation is developing.
The agency's commissioner said case workers spend all hours of the day all over the city, and the app will promote safety.
The agency is also launching a pilot program to give computer tablets to hundreds of child protective workers so they will have access to background reports while in the field.
