about us

For over 25 years, PERS has provided an emergency response telephone number for companies regulated by USDOT, including propane and heating oil marketers, as well as, thousands of other companies who ship or transport hazardous materials. Our center maintains emergency response and incident mitigation information for use by first responders and State or Federal agencies responding to or investigating an incident.


Answer After-Hours, a division of Professional Emergency Resource Services (PERS), was first introduced as a PERS service in 2005. Our answering service was initially created in response to frequent inquiries and requests from many of our DOT customers within the propane industry. It quickly became evident that traditional answering services were not meeting the needs of these companies, mostly due to a lack of industry knowledge and generalized software and procedures. Our collective knowledge and experience within PERS makes Answer After-hours the best telephone coverage solution available for your business needs. Contact us today to learn more.
