   The picture shows a woman working at her desk in a cubicle. The caption reads: "It is estimated that one in ten Canadians are hard of hearing or deaf. If you have hard of hearing or deaf employees, you must ensure that your office is equipped with visual fire alarms.

   Behind the woman, mounted on a wall near an exit, an audible fire alarm is shown to be ringing. The woman continues to work at her desk. The caption reads: "Offices with only an audible fire alarm pose a risk to people who cannot hear the alarm."

   While the alarm continues to ring, the woman's coworkers are seen to be evacuating through the office door. The woman continues to work at her desk. The caption reads: "In this example, people who can hear the alarm rush to the fire exit while a person who is deaf continues to sit at her desk."

   In first of the second set of animations, a visual alarm light is set in plain sight on the wall of the woman's cubicle. The caption reads: "Here, a strobe light that signals a fire alarm has been positioned within the line of sight for the employee who is deaf."

   Now when the audible alarm begins to ring, the strobe light begins to flash, immediately catching the woman's attention. The caption reads: "The strobe light is active at the same time as the audible alarm at a rate no greater than three flashes per second."

   The woman now joins her coworkers as they evacuate through the office door. The caption reads: "Thanks to the strobe light, the employee who is deaf is able to exit the building at the same time as all other employees."
