Fire Extinguisher Sign Large Safety

Description

A large-format fire extinguisher location sign in UV-rated PVC plastic. Red field with white symbol and “FIRE EXTINGUISHER” text — 300mm wide × 450mm tall. Designed for locations where the extinguisher must be visible from greater distances or in environments with reduced sightlines: high-bay warehouses, large factory floors, open car parks, and wide commercial spaces. The 300 × 450mm format provides increased symbol and text size compared to the medium (SILM), meeting the AS 2444 visibility requirement of 20m across larger spaces.

Under AS 2444:2001, fire extinguisher location signs must be clearly visible from any direction of approach up to 20m. In large open areas, high-bay storage facilities, or locations with visual obstructions, the large format sign provides the additional visibility needed to satisfy this requirement without additional signage. The SILL is also appropriate where ceiling heights are greater than standard — a larger sign mounted higher remains legible at distance in a way a smaller format would not.

Where to Use

• High-bay warehouses and large distribution centres
• Factory floors and large industrial workshops
• Open-plan commercial spaces — atriums, showrooms, large retail premises
• Undercover car parks and multi-level parking structures
• Sporting facilities, event venues, and exhibition halls
• Any location where the 20m visibility requirement demands a larger format sign

Key Features

• 300mm × 450mm format — large size for long-distance visibility
• UV-rated PVC plastic — resists fading and colour shift from UV exposure
• UV-rated PVC plastic — resists UV degradation, fading, and colour shift in exposed locations
• Durable plastic construction — suited to industrial and commercial environments

Compliance & Placement

Under AS 2444:2001 clause 3.3.4, fire extinguisher location signs must be mounted at not less than 2.0m above floor level. In large spaces, mounting the sign higher — at 3m or above in high-bay environments — increases visibility at distance. The sign must remain clearly visible from up to 20m in all directions of approach (clause 3.4). In high-bay locations where extinguishers are wall-mounted at standard height but the ceiling is 8–12m, mounting the large sign at 2.5–3.5m optimises visibility from the approach distance typical of that facility.

At each AS 1851 service, confirm the sign is present, undamaged, securely fixed, and visible from the 20m approach distance. In dusty industrial environments, periodic cleaning of the sign surface is recommended to maintain sign legibility.

Frequently Asked Questions

When do I need a large sign instead of a medium?

The AS 2444 requirement is that the sign must be clearly visible from up to 20m in all directions of approach. In most standard commercial spaces — offices, shops, standard warehouses with normal racking heights — the medium sign (SILM, 225 × 300mm) meets this requirement. The large sign (SILL, 300 × 450mm) is appropriate when: the approach distance is greater than standard; ceiling heights are significantly above average (making the sign appear smaller at distance); there are visual obstructions reducing line of sight; or the environment is dusty or has reduced ambient lighting. If you are unsure whether the medium format meets the 20m requirement for your location, use the large format.

How high should the sign be mounted?

AS 2444:2001 clause 3.3.4 specifies a minimum of 2.0m above floor level. In high-bay environments, mounting higher improves visibility — a sign at 3.5m in a 10m-high warehouse is more visible at distance than one mounted at the 2m minimum. The critical requirement is that the sign is visible from the 20m approach distance. The extinguisher handle itself mounts at a maximum of 1,200mm from the floor; the location sign is always mounted separately and higher.

Is UV-rated plastic required by the standard?

AS 2444:2001 specifies that location signs must use white symbols and text on a red field (clause 3.3.2), but does not mandate plastic material specifically for extinguisher location signs. UV-rated PVC plastic signage is standard for fire safety applications in Australia — it resists fading and colour shift from UV exposure, maintaining legibility over the life of the installation.

Does a single large sign cover multiple extinguishers?

Yes — AS 2444:2001 clause 3.3.3 permits a single sign to indicate multiple extinguishers grouped together, provided the sign is clearly visible to persons approaching any extinguisher in that group. If two or three extinguishers are installed on the same wall within close proximity, a single large location sign above them meets compliance provided all units are clearly visible from the sign’s position. Each extinguisher should still have its individual type identification sign (ABE, CO2, etc.) mounted adjacent to it.

What is the difference between the large sign (SILL) and the right-angle sign (SILS-ANGLE)?

The SILL is a flat sign mounted against the wall, visible from any direction facing that wall. The SILS-ANGLE is a two-panel sign that projects at 90° from the wall surface, making it visible simultaneously from both directions along a corridor or aisle — you can see the sign whether you approach from the left or the right. For long corridors where the flat sign would only be visible from one end, the right-angle format provides the required approach visibility in both directions. The SILL is the appropriate choice for open spaces where approach is from multiple angles to a wall-mounted sign.
