Danger of Infection Sign – ISO 7010 Shipboard Pictogram HS0078

Danger of Infection Sign (HS0078)

The HS0078 infection hazard sign is the standard ISO 7010 pictogram for Danger of Infection, used to warn crew, contractors, and visitors that a compartment or work area carries a risk of exposure to infectious agents or biological contamination. As with other ISO 7010 hazard pictograms, the design keeps the message instantly readable: no lengthy instructions, just a universally recognised warning that tells anyone approaching to stop, assess the risk, and follow the correct precautions before entering. For a ship’s crew, often multilingual, this kind of pictogram-first communication removes any dependence on shared language.

Within Safety Sign Hub’s Hazard Signs range, HS0078 fills a specific and often overlooked gap: marking spaces where biological rather than mechanical or chemical risk is the primary concern. Typical shipboard locations for this infection hazard sign include sick bays, isolation cabins, medical waste storage points, wastewater treatment compartments, galley waste handling areas, and quarantine holding spaces. On cruise ships and offshore support vessels, these zones require durable signage so infection control procedures are followed consistently across departments.

Like the rest of the Hazard Signs range, HS0078 is produced on rigid, marine-grade material with a self-adhesive option, and is available in photoluminescent variants for low-light visibility. The substrate resists saltwater, humidity, and UV exposure, keeping the sign legible for years in exposed passageways and machinery spaces.

Why Danger of Infection Matters

Infection risk is easy to underestimate compared with more visible hazards like fire, but the consequences of a missed exposure can be just as serious. An outbreak of illness, a pathogen exposure, or contamination spreading from an unmarked waste area can incapacitate crew, disrupt watchkeeping rotations, and in severe cases force a vessel to divert or restrict port access. Clearly marking these areas with an infection hazard sign reduces the chance that someone enters without gloves, a mask, or other required protective equipment.

Signage also plays a direct role in day-to-day safety management. During safety rounds, drills, and inspections, an infection hazard sign at the entrance to a risk area gives assessors immediate confirmation that the hazard has been identified, supporting the vessel’s broader hygiene management plan rather than relying on an undocumented verbal instruction passed between crew.

Compliance and Certification

HS0078 reproduces the internationally registered ISO 7010 graphical symbol set, the reference standard for safety and hazard signage. IMO shipboard safety signage guidance and the general safety provisions of SOLAS call for hazards to be identified with signage that is immediately understood regardless of a crew member’s first language, and Port State Control inspectors and classification society surveyors routinely check that hazardous compartments carry appropriate, undamaged signage during survey.

Installation Recommendations

Mount this infection hazard sign at eye level beside the entry point to the affected compartment, so it is the first thing anyone sees before entering. Where the space also has a hand hygiene station or PPE dispenser, position the sign so it visually pairs with that equipment, reinforcing the expected precaution. In corridors serving multiple risk areas, keep sign placement and mounting height consistent so crew build a reliable habit of checking for it.
