Do Not Remove Guards Sign

Do Not Remove Guards Sign

The Do Not Remove Guards sign is a worded prohibition notice fitted to machinery where a protective guard, cover, or shield must stay in place while the equipment is running. It is typically mounted directly on winches, pumps, compressors, steering gear, and rotating shafts throughout the engine room and deck machinery spaces, warning crew against lifting or unbolting a guard for a quick look while the unit is operating. Because moving parts left exposed can cause serious entanglement injuries within seconds, this sign gives engineers and deck crew a constant visual reminder at the exact point where the hazard exists.

This is a worded rectangular sign pairing a prohibition symbol with clear text stating the instruction directly, a format chosen because machinery guarding messages benefit from explicit wording rather than a pictogram alone. The sign carries IMPA code 33.8568 and ISSA code 47.585.68, the reference numbers ship chandlers and marine equipment suppliers use to source the correct panel when outfitting a vessel’s machinery safety signage. Safety Sign Hub keeps this design in stock, allowing engineering departments to add it to a machinery safety order without delay ahead of survey or dry dock.

Where Machinery Guarding Signage Belongs

This sign is best fitted directly onto or immediately beside the guard itself, rather than on a nearby bulkhead, so there is no ambiguity about which cover the warning applies to when several machines sit close together in a busy engine room. Common locations include belt guards on pumps, coupling guards on shafts, and mesh covers over winch drums, all points where a guard might be removed briefly for inspection or lubrication and then left off if crew are interrupted. Fitting the sign at the exact guard location also supports permit-to-work systems, since a technician can visually confirm the guard and its warning sign are both back in place before signing off a maintenance job as complete.

Safety Sign Hub manufactures this Do Not Remove Guards sign from fire-retardant material designed to withstand the heat, vibration, and oil exposure typical of engine room machinery spaces, where signage is often mounted within centimetres of hot surfaces or moving components. UV-stable inks keep the wording legible despite constant handling during maintenance, and the panel resists degradation from cleaning solvents and lubricants that frequently splash nearby. A rigid aluminium or polypropylene option withstands vibration from running machinery without the sign working loose or cracking over time, while an adhesive version suits smaller or curved guard surfaces where a rigid panel would not sit flush.

The sign is available as a self-adhesive label for direct application to a guard cover, and as a rigid panel that can be riveted or bolted alongside the guard’s fixing points for a more permanent installation. Both formats share the same wording and IMPA/ISSA reference, making it easy for a chief engineer to order matching signs for every guarded machine during a signage audit. Engineering teams reviewing their full inventory often check the broader prohibition signs range at the same time to cover related warnings in one order.

Reinforcing Safe Machinery Practices

Aligning machinery guarding signage with the pictogram and wording conventions of ISO 7010, detailed at iso.org, and with Australian Standard AS 1319, helps crew and visiting surveyors interpret the warning consistently regardless of which vessel or fleet they are working on. This matters particularly for engine room contractors and dry dock workers who move between different ships and need to recognise guarding warnings instantly rather than pausing to interpret an unfamiliar sign. Fleets that specify the same guarding signage across all vessels also make it easier to standardise machinery safety inductions for new crew joining any ship in the group.

During routine maintenance, guards are sometimes removed for cleaning or inspection and not always refitted immediately if a job is paused for a shift change, so pairing this sign with a simple guard-removal log at the machinery space entrance helps the next watch confirm nothing has been left exposed. Replacing a worn or missing Do Not Remove Guards sign as soon as it is noticed, rather than during the next scheduled signage review, closes a gap that could otherwise let a guard go back on without its warning attached. Many chief engineers keep spares in the engine store specifically for this reason, given how frequently guards are accessed compared with other machinery covers.
