Hanwell is the second most dangerous area in London for emergency staff, according to ambulance workers.
A high risk register which flags up danger addresses has been compiled by the London Ambulance Service.
The aim of the register is to keep workers safe by sending a police escort whenever there is a call to one of the listed homes.
There are 127 addresses flagged up in Hanwell, which were singled out based on previous experience of crews who believe there might be a risk of physical or verbal abuse at these households.
A total of 1,900 addresses around London have been included in the register.
The ambulance service began compiling the list after a sharp rise in reported assaults against ambulance staff, rising from 397 in 2006/07 to 673 in 2007/08 - an average of two attacks a day.
Hanwell councillors were surprised by these figures, as they believe Hanwell is a very quiet area. Councillor Phil Greenhead said: "I don't understand why anyone would want to attack emergency workers as they are so crucial."
And councillor Rosa Popham said: "I have not been made aware of the situation.
"If it is that serious I wish somebody would tell me about it, so that we can find a solution to put an end to this problem."
Carolyn Brown, of Hanwell Steering Group, added that the numbers are not at all representative of Hanwell.
She said: "Crime rates are average here, that does not correspond to the second place on that list."
A spokeswoman for Ealing Primary Care Trust said there had been no reports of threatening behaviour towards ambulance staff in Hanwell.
The other top five hotspots were Edmonton, Isleworth, Newham and Romford, each with more than 100 flagged addresses.
