Do your employees know the sounds of safety in your workplace? Do they understand protocol and procedures when the whistle blows? Failure to provide an adequate warning system can lead to injuries or fatalities in the workplace.


Below is some vital information for employers and managers about whistles and workplace safety.

Why Whistles are Vital to the Workplace

Whistles make employees and others in the area safer by providing an instant alert of existing or impending problems or danger. These reminders trigger worker senses, which can be faulty or weakened because of working conditions poor health, attention span, or distractions previous exposure to a situation.

●        Blasting

●        Underwater

●        Warehouse

●        Industrial processes

●        Transportation

●        Loading docks

●        High-security

●        Medical facilities


Employees are busy and focused on the task at hand, so they may not be paying attention to conditions around them. They may also be unaware of hazardous conditions occurring or developing in another area that could cause widespread injury or fatality.

●        Does the system comply with OSHA and ADA standards for alarms and security?

●        Has proper training and information been given to all parties working on the site?

●        Do employees know how to respond to a whistle warning?

●        Does each sound or repetitive pattern distinguish a specific alarm?

●        Do visitors, contractors and third-parties understand the alarm system?

●        Do employers update all parties when they have altered the warning system?

●        Do employers run systems tests to ensure that the warning system is still operational?

Assessing Workers’ Responses to Whistle Warnings

If workers are not responding to a whistle, employers must identify the reason why. It does not matter whether it’s one employee or multiple employees. Employers must identify which members of the work crew are not responding and assess the reason why.

●        False alarms

●        Similar or identical whistles for multiple purposes
