The Seasiders are currently nine points clear of safety, but after they suffered a 1-0 defeat to Bolton Wanderers on Tuesday night, Ferguson has revealed that he doesn't feel comfortable with his team sitting in 18th position.
The 36-year-old is quoted by BBC Sport as saying: "Do I feel safe with us being nine points above the drop zone? No. I do not feel that we are comfortable at all.
"It should have been 12 points above the drop zone because I thought that we were the better team, but it's not.
"We'll just move on to Saturday and we'll be ready for Queens Park Rangers. But I still feel that we are nowhere near safety yet."
Ferguson has just two wins from 12 matches since taking charge at Bloomfield Road in January.
