Non-Ionising Radiation Hazard Sign – ISO 7010 Pictogram HS0079

Non-Ionising Radiation Hazard Sign – HS0079

The Non-Ionising Radiation Hazard sign, catalogued under SKU HS0079, is the standard ISO 7010 pictogram for Non-ionising radiation, used to warn crew, contractors, and visiting personnel that they are entering an area where radar, radio-frequency, microwave, or other non-ionising electromagnetic emissions may be present. The sign functions as an instant, language-independent alert rather than a technical instruction, giving anyone approaching the marked zone a clear signal to check local procedures before proceeding, switch off personal transmitting devices, or avoid the area entirely while equipment is energised.

Within Safety Sign Hub’s Hazard Signs range, HS0079 sits alongside other electromagnetic and energy-source warnings and is one of the more specialised pictograms fitted aboard vessels with active radar, satellite communications, or radio equipment. Typical shipboard locations include radar masts and scanners, satellite dome platforms, bridge wing antenna arrays, and the radio room. Deck and electro-technical officers rely on this sign to keep unauthorised personnel clear of live radiating equipment during watchkeeping, maintenance, and port operations.

As with the rest of the range, this sign is produced in marine-grade materials: rigid photoluminescent polypropylene for bulkhead mounting, or durable self-adhesive vinyl for equipment housings and smaller surfaces. Both options resist saltwater spray, UV exposure, and the temperature swings typical of exposed deck and mast locations, so the pictogram remains legible for years without fading, cracking, or lifting at the edges.

Why Non-Ionising Radiation Matters

Unmarked or poorly maintained radiation-hazard signage creates a real and avoidable risk. Non-ionising sources on ships, particularly radar and high-power radio transmitters, can cause localised heating, RF burns, and eye or tissue damage at close range, and stray fields can interfere with pacemakers and other medical devices. Because the hazard is invisible and produces no sound or smell, personnel have no natural cue that a zone is active unless a posted warning tells them so.

A missing or faded Non-Ionising Radiation Hazard sign is a recurring finding during safety rounds and external audits, since assessors expect every energised radiating source to carry a permanent, correctly worded warning at the point of exposure. Keeping HS0079 installed and legible supports the vessel’s safety management system and gives officers a documented control for toolbox talks and permit-to-work reviews before anyone works near transmitting equipment.

Compliance and Certification

HS0079 reproduces a registered ISO 7010 safety sign, the internationally recognised graphical symbol set that IMO shipboard safety signage guidance and most flag and class requirements point to when specifying warning pictograms. Using the correct, unaltered graphic for non-ionising radiation keeps the warning consistent for multinational crews and shore personnel, in line with the general safety-signage expectations set out under SOLAS. Port State Control inspectors and classification society surveyors routinely check that hazard signage is present, current, and matches the registered design, so fitting an authentic pictogram helps avoid deficiencies during survey. For the full technical description, see the ISO 7010 registered safety signs database.

Installation Recommendations

Mount HS0079 at eye level on the approach to any radiating equipment, at the foot of ladders or platforms leading to radar and antenna positions, and on or beside the equipment housing itself. On masts and open decks, choose the rigid photoluminescent variant for secure fixing and visibility in low light; for control panels, radio room doors, or curved equipment casings, the self-adhesive version conforms cleanly and stays put in vibration-prone locations.
