Expands authority of emergency management departments in requesting assistance outside normal territorial jurisdictions.

S 1853 allows New Jersey emergency management officials, fire departments, police, and ambulance services to request assistance from neighboring municipalities during emergencies, even outside their normal jurisdiction. It ensures personnel providing aid have the same rights, immunities, and benefits (including workers' compensation) as if working in their home municipality, and sets standard payment rates: $3 per member and $35 per fire apparatus per hour for fire services, or $3 per member and $5 per vehicle per hour for police, unless otherwise agreed. This change directly affects all New Jersey municipalities participating in mutual aid agreements and aims to streamline emergency response coordination during crises.
