REGINA – New safety measures for late-night retailers including gas stations and convenience stores took effect in Saskatchewan on Tuesday.

Employers are now required to conduct a workplace hazard assessment and must develop written procedures for handling cash that minimize the amount of money that is accessible to the employee.

Employers must use video cameras for key areas in the workplace, including the cash desk and the outdoor pumps, and must post signs indicating the worker has limited cash and valuables.

In addition, lone late-night employees must have a check-in system and wear a personal emergency transmitter.

The changes come after gas station attendant Jimmy Wiebe was killed in June 2011 while working alone at a business in Yorkton.

Aaron Nagy, a friend of Wiebe’s who petitioned for changes, was unsuccessful in trying to convince the government that businesses should have at least two people on during night shifts.

“Our concern was that we don’t want to put two workers in harm’s way or three workers in harm’s way,” said Ray Anthony, director of safety services for the Ministry of Labour Relations and Workplace Safety.

“There is nothing that prevents an employer from having two workers if they wish to but if they wish to have a lone worker working there, you can use the emergency transmitter and the check-in system.”
