Do Not Use Unless Guards Are In Position Sign

Do Not Use Unless Guards Are In Position Sign

The Do Not Use Unless Guards Are In Position sign is a worded prohibition notice instructing crew never to operate a machine unless its protective guards are correctly fitted and secured. It is displayed on start switches, control panels, and starter boxes for equipment such as winches, compressors, lathes, and workshop tools found in engineering workshops aboard larger vessels. Placing the warning right at the point of operation, rather than only on the guard itself, catches a crew member’s attention at the exact moment they reach to switch the machine on, reducing the chance of an oversight during a rushed job.

This worded rectangular sign combines prohibition symbolism with direct text confirming that guards are in position before use is permitted, a format suited to an instruction with a specific condition attached rather than a single-word prohibition. The sign corresponds to IMPA code 33.8569 and ISSA code 47.585.69, the catalogue numbers ship chandlers and marine safety suppliers use to source the exact panel for a vessel’s workshop and machinery signage kit. Safety Sign Hub stocks this sign ready for despatch, so engineering superintendents can add it to a workshop safety order alongside related guarding notices.

Fitting This Sign At The Point Of Operation

Because this warning applies specifically to the moment a machine is switched on, it works best mounted directly beside the start button, isolator switch, or control panel rather than elsewhere in the workshop where it might be overlooked during a busy shift. Workshop supervisors often use it on bench grinders, drill presses, and portable power tools stored in a shared engineering locker, reminding whoever picks up the equipment next to check that guards are in position before starting work, regardless of who used the tool previously. This is particularly useful on vessels where several crew share access to the same workshop tools across different watches, since the sign does not rely on a verbal handover to communicate the requirement.

Safety Sign Hub produces this sign from fire-retardant, durable material suited to workshop environments where signage may be exposed to metal filings, oil, and coolant splashed from nearby machining work. UV-stable printing keeps the wording sharp despite frequent handling and cleaning around workbenches, and the panel resists cracking from the vibration of nearby running equipment. A photoluminescent option is available for workshops with limited fixed lighting, and standard ISO panel sizing means the sign fits neatly alongside other prohibition and mandatory notices already fitted around the engineering spaces.

Stock is held as a self-adhesive label for direct application to a control panel or bulkhead near the machine, and as a rigid panel for a more permanent fixing where the sign needs to withstand rougher workshop handling. Both formats carry the same wording and IMPA/ISSA reference, simplifying reorders when outfitting additional workstations. Workshops reviewing their full signage needs often browse the wider prohibition signs catalogue at the same time to cover related machinery warnings in a single order.

Reinforcing Guarding Requirements Fleet-Wide

Specifying signage that follows the wording and layout conventions established by ISO 7010, detailed at iso.org, and Australian Standard AS 1319 helps ensure that when guards are in position and a machine is switched on, every crew member interprets the warning the same way regardless of which vessel they normally serve on. Fleet operators standardising this sign across sister ships find it easier to run consistent workshop safety inductions, since new crew transferring between vessels already recognise the format and message from their previous posting rather than encountering a locally improvised notice.

Workshop equipment often changes hands multiple times across a single day, so a quick visual check that guards are in position before switching on becomes second nature when the reminder is fixed permanently at the control point rather than left to memory. Superintendents preparing for an annual survey frequently review workshop signage alongside machinery guards themselves, replacing any sign that has become scratched or faded from years of oily hands brushing past it. Keeping a couple of spares in the engineering store means a damaged sign can be swapped out immediately rather than leaving a control panel without its warning until the next port call.
