SE675 Combination Shower & Eye Wash Hand Operated No Bowl

Emergency safety showers in Australia must comply with AS4775-2007 — Emergency Eyewash and Shower Equipment. This is Australia's equivalent of the international ANSI/ISEA Z358.1 standard. For any Australian business where workers may be exposed to hazardous or corrosive chemicals, compliance is mandatory under WHS legislation.

AS4775-2007 sets minimum requirements for:

• Flow rate and flush duration
• Shower head height and spray pattern dimensions
• Tepid water delivery (water temperature range)
• Activation method and stay-open valve design
• Location, access path, and signage
• Weekly inspection and testing intervals

All safety showers in BIG Safety's range - including the full Speakman series - are manufactured and tested to comply with AS4775-2007.

The minimum flush time required is 15 minutes of continuous flushing at a primary eyewash station, as specified by AS4775. This duration is based on medical evidence that many chemical injuries continue to progress during the initial minutes after exposure, and that adequate, uninterrupted flushing is necessary to dilute and mechanically remove the contaminant from eye tissue.

The correct emergency response sequence is:

1. Activate the nearest eyewash station within 10 seconds of the exposure event
2. Hold eyelids open and allow water to flush both eyes simultaneously
3. Continue flushing for the full 15 minutes without stopping - even if discomfort appears to decrease
4. Seek immediate medical attention after flushing is complete, regardless of the apparent severity of the injury

For workers using a personal eyewash bottle as first-flush, the bottle should be activated immediately at the point of exposure, and then the worker must proceed to a primary plumbed or self-contained eyewash station for the complete 15-minute flush.

An aerated eyewash mixes air into the water stream before it exits the nozzle, producing a soft, bubbling flow rather than a hard direct jet of water. This delivers two important safety advantages:

First, the aerated stream creates a gentle scrubbing action that dislodges and flushes contaminants from the sensitive mucous membranes of the eye more effectively than a flat water stream.

Second, the softer, lower-impact flow reduces the risk of additional trauma to an already irritated or chemically burned eye. This also encourages the injured worker to keep their eyes open and maintain flushing for the full 15 minutes - a critical factor in limiting long-term injury.

All Speakman eyewash stations at BIG Safety feature aerated dual-stream nozzles that deliver a minimum of 12 litres per minute in a spray pattern shaped to closely follow the natural contour of the eye socket.

A combination eyewash and safety shower is the recommended choice whenever a worker could sustain both eye and whole-body chemical exposure simultaneously - such as in chemical manufacturing, industrial processing, or laboratory environments where large volumes of corrosive or hazardous liquids are handled.

Combination units allow a single injured worker to flush their eyes and drench their body at the same time, without needing to move between two separate stations. This is especially important when a worker is in pain or disoriented. Under AS4775, when a combination unit is installed, both the shower and eyewash elements must be capable of simultaneous operation without causing a reduction in flow rate or pressure in either component.

Standalone eyewash stations are appropriate where the hazard is limited to the face and eye area only - for example, bench-level chemical handling in a laboratory or light dust exposure in a workshop.

An eyewash station delivers flushing fluid specifically to the eye area — two nozzles positioned to flush both eyes simultaneously. It does not provide coverage across the full face.

An eye and face wash station includes additional side jets or nozzles that extend flushing coverage to the cheeks, forehead, and surrounding facial tissue. It must deliver a significantly higher minimum flow rate - 11.4 L/min versus 1.5 L/min for eyewash only - to cover the larger surface area adequately.

Choose an eye and face wash station when workers face airborne hazards such as chemical mist, fumes, fine dust, or splash risks that could contact the entire face rather than just the eyes. BIG Safety stocks Speakman's SE480 (pedestal) and SE400 (wall mounted) eye/face wash models for these higher-risk applications.

There are five main types of eyewash station, each suited to different workplace environments:

• Plumbed eyewash stations (wall, pedestal, bench, or over-sink mounted) — permanently connected to a building's water supply. Best for facilities with a fixed hazard location and reliable plumbing infrastructure.
• Portable self-contained units (45L, 106L) — pressurised stainless steel tanks filled with potable water. Best for remote sites, construction, mining, and agriculture where no plumbing is available.
• Combination eyewash and safety shower units — provide simultaneous eye, face, and full-body decontamination from a single station. Recommended wherever whole-body chemical exposure is a risk.
• Eye and face wash stations — deliver higher flow (11.4+ L/min) to flush both eyes and the full face, including cheeks and forehead. Suited to environments with airborne chemical, dust, or mist hazards.
• Personal and supplemental eyewash bottles — small first-flush units kept at the point of exposure. These do not replace primary stations; they provide immediate flushing while the worker moves to a full eyewash station.

Product selection should always be based on a documented risk assessment that considers hazard type, the body areas at risk, number of workers exposed, and site plumbing availability.

Yes - water temperature is a critical compliance and safety factor. AS4775 requires eyewash stations to deliver tepid water, generally defined as comfortable for extended flushing and below 38°C. Extremes of hot or cold water can cause additional injury, deter a worker from flushing for the full 15 minutes, or cause shock.

For outdoor installations or sites where pipework or tanks are exposed to direct sun, a scald protection (thermostatic mixing) valve is strongly recommended to prevent scalding. For cold-climate sites, insulated or heated units are available. Tepid water compliance should be factored into every site risk assessment when selecting and installing eyewash equipment.

Correct use of a safety shower in the first moments after exposure is critical to minimising injury severity. Workers should be trained to follow this sequence:

1. Activate immediately - reach the shower within 10 seconds of exposure and pull the activation handle or step on the foot pedal. The stay-open valve will hold the shower running without further operator input.
2. Remove contaminated clothing - use both hands to remove saturated clothing and PPE as quickly as possible. Chemical exposure through saturated clothing continues even during flushing.
3. Position fully under the spray - stand with the full spray pattern covering the affected body area. The spray diameter is a minimum of 508mm at shoulder height, designed to cover the full upper body simultaneously.
4. Flush for a minimum of 15 minutes - do not stop early, even if discomfort appears to reduce. Dilution and mechanical removal of chemical agents from skin tissue takes the full duration.
5. Activate the eyewash simultaneously if eyes are affected - on a combination unit, the integrated eyewash can be operated at the same time as the shower from the same station.
6. Seek immediate medical attention - after the flush, the worker must be assessed by a medical professional regardless of the apparent severity of the injury.

Regular first aid training and emergency drills significantly improve response speed and compliance when an actual exposure event occurs.

AS4775 requires that plumbed safety showers be activated and tested weekly. The purpose of weekly activation is to:

• Flush stagnant water from the supply line, reducing the risk of bacterial contamination - including Legionella pneumophila - in standing water between uses
• Verify that the activation valve opens freely and the stay-open mechanism functions correctly
• Confirm adequate water flow and spray pattern at the shower head
• Identify any visible damage to the shower head, bowl, nozzles, or activation handle before an emergency occurs

In addition to weekly activation, a formal annual inspection by a suitably qualified technician is required. This should cover plumbing connections, valve integrity, thermostatic mixing valve calibration (if fitted), and overall compliance with installation requirements including shower head height and spray pattern.

Inspection records must be maintained on site. In the event of a workplace incident, documented maintenance history is critical evidence for WHS compliance and workers compensation purposes.

A safety shower that cannot be quickly returned to service after use or maintenance failure represents an ongoing compliance gap and a real safety risk. BIG Safety recommends maintaining an on-site inventory of common Speakman spare parts, including:

• Shower head assembly - the most commonly replaced component after heavy use, physical impact, or mineral scale buildup
• Stay-open ball valves - the 25mm shower valve and 15mm eyewash valve, along with associated seals and O-rings, should be inspected annually and replaced when showing wear
• Eyewash nozzles and dust caps - nozzles can become blocked with sediment or mineral deposits between uses; dust caps protect nozzles from contamination and should be replaced when cracked or missing
• Activation rods and foot pedals - mechanical components subject to wear in high-traffic or harsh outdoor environments
• Thermostatic mixing valve cartridges - if a tepid water mixing valve is installed, the cartridge requires periodic replacement per the manufacturer's maintenance schedule
• Eyewash bowl and drain assembly - for combination units with a stainless steel bowl, the bowl and drain seal should be checked at each inspection

BIG Safety stocks the full range of Speakman accessories and spare parts. Maintaining critical spares on-site eliminates extended periods of non-compliance while waiting for parts to be shipped.

Yes. AS4775 requires that safety showers and eyewash stations be clearly identifiable in all operating conditions. Compliant signage serves two functions: it helps an uninjured co-worker quickly locate the unit to assist a casualty, and it helps an injured worker with impaired vision navigate to the station as quickly as possible.

Requirements and best practice include:

• AS4775-compliant emergency shower and eyewash signs — standard green and white poly or photoluminescent signs mounted prominently above or near the unit
• Green indicator light — strongly recommended by AS4775 for visibility across open factory, warehouse, or outdoor work environments
• Floor markings — yellow safety zone floor markings around the unit; this area must remain permanently clear of stored goods, pallets, or equipment at all times
• High-visibility unit colour — Speakman units feature yellow shower heads and activation handles for rapid visual identification even in busy or low-visibility environments

BIG Safety stocks the full range of AS4775-compliant emergency shower and eyewash signs in poly and metal format to suit all installation types.

AS4775 sets the following mandatory placement requirements for emergency safety showers:

• 10 seconds from the hazard: the shower must be reachable in no more than 10 seconds from the point of potential exposure - typically within 10-15 metres on a clear, level path
• Same level as the hazard: the shower must be on the same floor level as the hazard - no stairs, steps, or ramps between the hazard point and the unit
• Unobstructed path: the travel path must remain clear at all times, wide enough for an injured worker moving without full vision
• Clearly identified: must be signposted with AS4775-compliant emergency shower signage and ideally a green indicator light visible across the work area
• Well illuminated: sufficient lighting to make the station visible in normal and emergency operating conditions

Special case - strong acids and caustics: for workplaces handling concentrated acids or caustic substances, AS4775 recommends the eye/face wash component be positioned immediately adjacent to the hazard, not merely within 10 seconds of travel.

Most Speakman safety showers at BIG Safety are hand and foot operated — they include both a triangle pull rod for hand activation and a foot pedal for activation of the eyewash, giving the injured worker maximum flexibility regardless of the nature or location of their exposure.

Hand activation (pull rod) is the standard method. The worker pulls the triangle handle downward to open the stay-open full-flow ball valve — the shower then runs continuously without the worker needing to hold anything.

Foot activation is critical when a worker's hands are contaminated with hazardous substances — for example, after a chemical splash to the arms or hands - as it avoids transferring contaminants to the face or eyes during activation.

All AS4775-compliant safety showers use stay-open valves, meaning once activated, the unit flows continuously without any ongoing input from the operator. This allows a worker to use both hands freely to remove contaminated clothing and hold their eyes open during the eye flush.

A combination unit — where the safety shower and eyewash are integrated into a single station — is the preferred solution whenever a worker could sustain chemical exposure to both the eyes and the body simultaneously. This is the most common scenario in chemical manufacturing, laboratories, industrial cleaning, fuel handling, and battery maintenance.

The key advantage of a combination unit is that a single injured worker — even one in significant pain or unable to see clearly — can activate both functions simultaneously without needing to locate or move between separate pieces of equipment.

Under AS4775, a combination unit must be capable of operating both the shower and eyewash simultaneously without a pressure drop in either component. All Speakman combination units at BIG Safety are designed and rated to meet this requirement.

Separate units may be appropriate where the exposure hazard is clearly limited to either the eyes and face or the body, but not both - for example, a shower-only station at a chemical drum decanting area, or an eyewash station at a laboratory bench. A documented risk assessment should determine the correct configuration for each hazard point.

Under AS4775-2007, an emergency safety shower must deliver a minimum of 75.7 litres per minute (L/min) of flushing fluid for a continuous duration of at least 15 minutes. This flow rate is set high enough to rapidly dilute and flush hazardous substances from the entire body surface.

The Speakman combination shower units at BIG Safety — including the SE607, SE612, and SE675 — all deliver 76 L/min, meeting the AS4775 minimum.

No - eyewash stations are first aid equipment, not risk control measures. Under Australia's Work Health and Safety (WHS) legislation and the hierarchy of controls, employers are required to first eliminate, substitute, isolate, or engineer out chemical hazards before relying on PPE or emergency response equipment. Eyewash stations sit alongside PPE at the bottom of the hierarchy - they address the consequence of an accident, not its cause.

In a compliant WHS safety plan, eyewash stations should be:

• Identified as part of a documented risk assessment that considers hazard type and exposure scenarios
• Selected based on the nature and severity of potential chemical exposure
• Incorporated into emergency response procedures, with clear worker training on location and use
• Regularly tested and maintained, with inspection records kept on site
• Provided in addition to - not instead of - appropriate eye protection PPE such as safety glasses, chemical goggles, or face shields

Providing an eyewash station does not reduce the employer's obligation to supply and enforce proper PPE and primary hazard controls.
