Automatic Start Sign

Automatic Start Sign – ISO 7010 Warning Symbol HS0039

This Automatic Start sign warns crew and contractors that the equipment nearby is controlled automatically and can start or stop without any local warning or human intervention. The sign combines the standard black exclamation triangle with a bold “WARNING – Motor starts and stop automatically” text panel beneath it, giving anyone working near the machine an instant visual cue plus an explicit written instruction in a single fixture.

As SKU HS0039 in the Hazard Signs range, it is built for continuous marine exposure and suits pump rooms, HVAC plant, compressor rooms and any compartment where automated control systems bring motors on and off line unattended.

The upper section shows the familiar black exclamation mark inside a warning triangle, while the lower panel spells out “WARNING” in bold capitals followed by “Motor starts and stop automatically” in smaller text, a combined pictogram-and-wording format that removes any assumption crew might otherwise make that a stationary motor is safe to approach.

Because automatically controlled equipment can restart the moment a sensor or timer condition is met, the written panel gives maintenance staff the specific context a generic triangle alone cannot provide. The photoluminescent base keeps the automatic start warning visible for a period after lighting fails, useful in machinery spaces where equipment continues cycling during a temporary power interruption.

Why Automatic Start Marking Matters

Unexpected start-up remains one of the most common causes of serious injury around pumps, fans and compressors, particularly when a motor that appears idle is in fact waiting on an automatic control signal.

Clear automatic start signage at every relevant machine supports lock-out/tag-out procedures during maintenance and reminds crew never to assume a stationary motor is switched off, and the explicit wording on this sign format helps ensure the message is understood even by crew or visitors less familiar with pictogram-only conventions. It also gives supervisors a clear reference point when briefing new starters on which equipment in a space is automatically controlled.

Compliance and Certification

This sign is produced to align with IMO shipboard safety signage guidance and the combined pictogram-and-text warning format used across shipping and industrial machinery safety, supporting the ISM Code’s requirement for documented control of mechanical hazards. A visible automatic start warning at every automatically controlled pump, fan or compressor is a documented control that classification surveyors and internal safety auditors expect to see during a machinery safety review.

Installation Recommendations

Mount the sign directly on or beside any motor, pump or fan controlled by an automatic starter, at a height that is seen before hands or clothing come near moving parts. Use the pre-drilled fixing holes with marine-grade fasteners for exterior and high-vibration machinery spaces, and the self-adhesive backing for interior guarding and control panel applications. Confirm during permit-to-work reviews that the sign remains legible on every relevant machine, particularly after guarding or equipment has been serviced.

• 425 x 567mm rigid or self-adhesive format for steel, aluminium or GRP surfaces
• Photoluminescent base for visibility during power loss or blackout drills
• UV-stable, saltwater-resistant construction for long-term exterior exposure
• Self-adhesive or pre-drilled fixing options for fast, secure installation
• Combined pictogram and bold English text for added clarity beyond the symbol alone
