General :: Purging Binary Logs In MySQL Replication?

I had Configured a MySQL Master-Slave replication.It seems that the binary logs steals so much space of My storage.

i.)My Master

show master status;

+------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000144 | 475823 | | |
+------------------+----------+--------------+------------------+
1 row in set (0.00 sec)

ii.)My Slave.

mysql> SHOW SLAVE STATUSG;
*************************** 1. row ***************************
Slave_IO_State: Waiting for master to send event
Master_Host: 10.277.55.141

[code]....

If i remove all binary files up tp mysql-bin.000144 using "PURGE",will it affect my existing database/any data loss.
