1.  Emergency services seem impotent in the face of such a disaster.

2.  Emergency services such as medical supplies must be maintained at all times.

3.  Emergency services were on standby after someone called to say there was a bomb in the city centre.

4.  He had to watch the minutes tick away while the emergency services tried to locate him.

5.  Indeed, May I express once again our great admiration for the skill and courage of those involved in our emergency services?

6.  Obviously, the emergency services are run off their feet.
