45 Litre Portable Eye & Body Wash

Yes - this unit exceeds Australian Standards AS4775-2007 for Emergency Eyewashes

1. Fill unit half way and add SE 4210 water preservative (if desired) and then fill to water line with CLEAN POTABLE WATER.
2. Pressurise the tank to 690 KPa with clean air. Check for leaks.
3. The unit has a Schroeder valve, same as a car tyre tube valve.
4. The unit needs to be inflated to 690 kPa. A clean filter air compressor will work or there are some battery inflators on the market Milwaukee.etc, They take a bit longer but will eventually get it up to pressure.

Note:- Anti Microbial Water Preservative is not essential,
however it maintains water quality for up to 120 days. After 120 days the water
needs to be completely replaced. If water preservative is not used, then the
water must be fully replaced approximately every 2 weeks.

The water in a portable eyewash unit needs to be replaced every two weeks (approximately) to ensure there are no growths in the water. Antimicrobial Water Preservative can be used to prolong the life of the water for up to 120 days. https://bigsafety.com.au/products/anti-microbial-solution

This is not a Safety Shower as it does not provide 76LPM of water to spray the body for 15 minutes. The Shower head/body wash/drench hose is referred to as supplementary equipment to be used in a first response emergency treatment at the site.

You do not have to order the Trolley/Hand Truck, however customers have found it makes life easy to reposition the unit around site, to have it close to where it is needed.

These units are generally shipped in 3-5 business days, as they are assembled, quality inspected and pressure tested before shipping

We mainly use TNT & Border Express dependant on the delivery location throughout Australia.

All emergency eyewash and shower equipment in Australia must comply with
AS4775-2007 — Emergency Eyewash and Shower Equipment. This is the Australian
equivalent of the international ANSI/ISEA Z358.1 standard. For Australian
businesses that work with hazardous chemicals, using AS4775-compliant equipment
is mandatory. The standard sets minimum performance requirements for flow rate,
flush duration, water temperature, placement, activation method, and ongoing
maintenance. All eyewash stations stocked by BIG Safety comply with
AS4775-2007.

Under AS4775-2007, minimum flow rate and duration requirements vary by equipment
type:

- Plumbed and self-contained eyewash stations: minimum 1.5 L/min for 15
continuous minutes

- Eye and face wash stations: minimum 11.4 L/min for 15 continuous minutes

- Emergency safety showers: minimum 75.5 L/min for 15 continuous minutes

- Drench hoses (supplemental equipment): flow must be non-injurious to the user
— no fixed minimum

The 15-minute minimum flush duration applies across all primary equipment types. Flushing fluid must be delivered to both eyes simultaneously at a velocity low enough to avoid injury to delicate eye tissue.

Under AS4775, eyewash stations must be:

- Located no more than 10 seconds' travel time from the identified hazard - typically within 15 metres

- On the same level as the hazard, with no steps or level changes between the hazard and the unit

- Accessible via a clear, unobstructed path that an injured worker can navigate without full vision

- Clearly identifiable with AS4775-compliant signage, and ideally marked with a green indicator light

- In a well-illuminated area so the station is visible in all operating conditions

All workers and visitors must be trained on the location of the nearest station and how to activate it quickly.

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.

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.

You can use the Big Safety Safety Shower and Eyewash Decision Flow Chart  to assist in determining the correct equipment for your needs.

Portable self-contained eyewash stations are essential wherever a fixed plumbed water supply is unavailable or impractical. Common applications in Australia include:

• Mining and resources - remote and fly-in-fly-out sites with no plumbing infrastructure
• Construction and civil works - temporary site setups, formwork, concrete, and demolition environments
• Agriculture - handling of pesticides, herbicides, and fertilisers in the field
• Emergency services, Military and hazmat response - fire crews, SES, and chemical spill response teams
• Transport of dangerous goods - commercial vehicles and drivers carrying classified hazardous substances
• Laboratories and research facilities - as supplemental first-flush equipment alongside permanent plumbed units
• Outdoor events and temporary facilities - any situation requiring mobile safety compliance

In most circumstances, no - but there is an important distinction. Under AS4775, portable self-contained eyewash stations are classified either as primary self-contained equipment or as supplemental equipment, depending on their capacity and compliance with flow rate requirements.

Self-contained units such as the SE590A 45L and 106L, which can deliver 1.5 L/min for a continuous 15-minute flush, may serve as primary eyewash equipment on sites where no plumbing is available - provided a risk assessment confirms they are suitable for the specific hazard.

Smaller personal eyewash bottles and hand-held units are classified as supplemental equipment only. They provide immediate first-flush support but must be followed by a full 15-minute flush at a primary plumbed or self-contained station.

Where plumbing is available, a plumbed station is always the preferred primary solution. Portable units in that context serve as backup or supplemental equipment. A documented risk assessment is required to determine the correct classification for any given site.

The right capacity depends on your flush duration needs and whether the unit will provide both eyewash and body wash simultaneously.

The SE590A 45L delivers the eyewash component at 1.5 L/min for 15 minutes, using approximately 22.5 litres for eye flushing alone. The remaining volume supports the drench hose for body washing. This unit suits smaller teams and single-person use at sites with lower overall chemical exposure risk.

The SE590A 106L delivers the eyewash component at 2.3 L/min for 15 minutes and provides substantially more volume for simultaneous body washing via the drench hose. It is better suited to sites with higher chemical exposure risk, larger teams, or environments where both eye and body decontamination may be required at the same time.

As a general rule, a larger capacity unit provides a greater safety margin and reduces the risk of the unit running dry during an active emergency flush.

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.
