The role of whistles in the industrial sector

Here at ACME Whistles, we have a long and celebrated history when it comes to producing industrial whistles of all kinds, and to this day we are able to offer a versatile range of such whistles. These highly specialised pieces of equipment are produced in our UK-based factory, largely using traditional hand tooling methods and our original manufacturing equipment.

You might be surprised by just how widespread the use of whistles is in the industrial sector. Though they are a relatively simple piece of equipment, they are incredibly useful and versatile, and can be applied in many sectors, either as integral parts of machinery or commonly as features within robust health and safety features in the workplace.

What makes industrial safety whistles ideal for the workplace?

One of the things that makes whistles particularly suitable for industrial applications is the fact that they produce aeroacoustic sound, meaning that the only thing required to produce the whistling sound is air. This is particularly important because it means that whistles will operate perfectly during a power outage or similar event. Therefore, their use as a safety or advance warning feature can be relied on even when other parts of the system may fail.

In terms of industrial machinery and equipment, whistles have long been used as a reliable and low-tech means of signalling pressure changes. For example, industrial systems that involve the movement of steam or pressurised gas often make use of whistles to alert workers that pressure is high and is being released via a valve. A related example of whistles being used in a similar way is with steam-powered locomotive engines. Steam whistles used within manufacturing or other industrial settings work in a similar way.

How and where are industrial safety whistles deployed?

Where sound-based solutions are needed, and in situations where worker safety depends on the availability of a failsafe, backup system for more high-tech monitoring equipment, the importance of whistles cannot be overstated. Though electronic monitoring systems are commonplace these days, they can be subject to failures such as power outages and system errors that can make them less reliable.

To remedy this, an industrial safety whistle should be incorporated into the pressure-sensitive system. We have developed the ACME Low Pressure Warning Whistle LP 15/10 which operates at 10 Bars and warns of low pressures, and the ACME High Pressure Warning Whistle HP 15/18 which does the opposite and warns when system pressures rise, operating at 15 Bars. ACME Low Pressure Whistle 579.5 works a little differently and provides a warning when pressure is falling within a system.

One of the most common applications for these pressure warning whistles is within hydraulic braking systems. Often, these can be found in manufacturing plants where they are used as a backup to alert workers to abnormal conditions within the machinery. They are the last line of defence when electronic systems let you down, and something you can truly rely on.

Other kinds of industrial safety whistle for the workplace

Aside from our carefully engineered pressure warning whistles, we provide a complete range of safety whistles that can be deployed in any kind of workplace to help keep you, members of the public and your teams safe. For example, the ACME Thunderer whistle is commonly used in rail signalling, and station staff will use them to let train drivers know that all the doors are closed, no one is in the way, and it is safe for them to begin manoeuvring away from the station.

In a more general sense, they can be used to convey messages between team members to alert to hazards and to ensure safe procedures in the workplace.
