What safety feature should be used for pneumatic tools at connections?

The use of safety lashings is essential for pneumatic tools at connections to prevent accidental disconnection during operation. When pneumatic tools are in use, the high-pressure hoses and connections can become a hazard if they are not properly secured. Safety lashings provide an additional layer of security, which helps to ensure that hoses and fittings remain connected under pressure. This is crucial because a sudden disconnection can cause hoses to whip dangerously, potentially leading to injuries or equipment damage.

In contrast, safety locks, protective gloves, and sound alarms serve different purposes. Safety locks are typically used to prevent unauthorized use of tools or machinery, which does not directly address the issue of connection integrity in pneumatic systems. Protective gloves are critical for safeguarding hands from cuts and abrasions but do not prevent accidents related to tool connections. Sound alarms are useful for signaling hazards but do not contribute to the physical security of pneumatic tool connections. Therefore, employing safety lashings is the most effective way to enhance safety at connections for pneumatic tools.
