Farmers could be more at risk than other groups in the freezing conditions, the Health and Safety Authority warned.
The agricultural sector has been singled out as one of the danger areas, and farmers are advised to take extra care and avoid unnecessary risks, especially when working alone.
"If work must be undertaken on the farm alone, let someone know where you are and what time to expect you back at," advised chief executive Martin O'Halloran. "Avoid any outdoor work that can wait until conditions are more amenable."
He also urged farmers to seek the assistance of a neighbour if needed, as well as keeping an eye out for their neighbours' wellbeing.
Ten people lost their lives as a result of farm accidents last year compared to 21 in 2008.
There was also a 25pc decrease in worker deaths in general last year.
