Do Not Touch Sign

Do Not Touch Sign

A do not touch sign is fitted near machinery, electrical equipment, or surfaces that present a hazard on contact, such as heat, moving parts, or stored energy that is not always obvious from appearance alone. Aboard a vessel this pictogram commonly appears on exhaust lagging, hot pipework, recently painted surfaces, and equipment left running for testing or calibration, giving crew and visitors an instant warning before they reach out to steady themselves or investigate something unfamiliar. It is a general-purpose prohibition suited to any surface or item where contact carries a real, if not always visible, risk.

The pictogram shows a black silhouette of a hand reaching toward an object, struck through by the red diagonal bar and circle common to the ISO 7010 prohibition series, with no text required for the message to register. This do not touch sign carries IMPA code 33.8548 and ISSA code 47.585.48, the maritime catalogue codes ship chandlers and marine safety suppliers rely on to supply the exact pictogram a vessel’s safety officer has specified, rather than a similar-looking substitute.

Common Hot Work and Machinery Applications

Exhaust manifolds, turbocharger housings, freshly welded fittings, and equipment undergoing hot testing are typical locations for this sign, often fitted temporarily during maintenance rather than as a permanent fixture. It is also used on electrical panels and terminal boxes during fault-finding, where a technician wants a clear, immediate warning visible to anyone else entering the space while work is in progress. Engineers assembling a maintenance signage kit frequently pull items from our full range of prohibition signs alongside this do not touch sign to cover both the touch hazard and any related isolation or lock-out notice needed for the same job.

The sign is printed on fire-retardant material able to withstand placement close to genuinely hot surfaces without degrading, along with UV-stable ink that keeps the pictogram legible whether it is used on an exposed weather deck or inside an engine room. A magnetic or adhesive-backed rigid option suits temporary placement during a maintenance job, where the sign needs to be moved from one piece of equipment to another as work progresses through a planned maintenance schedule. The printed face also resists smearing from oily hands, a detail that matters given how often this particular sign gets handled during a job compared with a permanently fixed pictogram.

Stock is held in both self-adhesive vinyl for smooth casings and rigid panel for hooking onto machinery guarding or handrails during temporary use. Quoting IMPA 33.8548 or ISSA 47.585.48 when reordering ensures the correct do not touch sign is supplied for the specific hazard identified, rather than a general caution sign that lacks the same instant pictogram recognition. A small compact format is the most practical choice for temporary use, easy to store in quantity in the engineers’ workshop between jobs.

Reinforcing Hot Work and Contact-Hazard Awareness

Managing contact hazards during maintenance work is a recurring theme in workplace safety guidance from Safe Work Australia, and the ISO 7010 pictogram behind this sign gives vessel operators a ready-made, internationally recognised way to flag the same risk without drafting custom wording for every job. Fitting a consistent do not touch sign across a fleet’s engineering department means every ship’s maintenance kit looks and functions the same way, regardless of flag or trading route. It also gives a newly joined engineer a familiar visual cue from the first watch, rather than having to learn a different informal system aboard each new vessel.

A second engineer preparing for a scheduled overhaul will typically pull several of these signs from stores at the start of the job and place them on each piece of equipment as it is opened up or left running for testing, moving them along as the work progresses through the vessel’s machinery spaces. Having a ready supply on hand, rather than sourcing one sign at a time mid-job, keeps the engine room properly marked throughout an overhaul that might otherwise leave gaps in warning coverage as equipment states change hour to hour. Returning the signs to stores once the job is signed off, rather than leaving them in place indefinitely, also keeps the warning meaningful the next time it is actually needed.
