Frequently Asked Questions

CRG maintains two facilities in Sydney and Melbourne, providing customer backup in case of emergencies such as power outages in either city. This also provides scalable capacity to meet customer emergencies including urgent orders that require higher-than-normal product or service delivery, and it gives customers a high level of comfort that product/service delivery will be uninterrupted.

Yes, your garments will still be processed and done so on time because of our dual supplier policy. With at least two alternate suppliers, we can ensure constant supply. This policy covers gas supplies, sterile bags and other high-demand and crucial items. We also have a duplicated in-house supplier system. Running a dual boiler configuration in Sydney and Melbourne ensures constant supply in the event of damage to one machine. Our facilities also have dual sterilisers, stand-by washing machines and dryers, as well as dual air conditioners and chillers. We also maintain an off-site IT-backup facility, which can be used to run the Sydney or Melbourne facilities.

All of our chemicals and other supplies are securely warehoused in both Sydney and Melbourne. By holding vital supplies in multiple locations, we can deliver backups in case of accidents in Sydney or Melbourne. Should shortages occur in either city, emergency supplies can quickly be freighted in.

Having multiple manufacturing sites for our products provides us with the ability to increase production to meet sudden demands.

We maintain two facilities with AS/NZS ISO 9001:2000- Quality Management Systems accreditation. We also have NATA accredited laboratories, which enable us to provide specialised testing services.

The main purpose of cleanroom clothing is to contain the spread of particulate and microbial contaminants. Cleanroom clothing is generally designed to protect the environment and the product being manufactured (Packaging People to Protect Products). However, on some occasions it is also necessary to protect the person from the product as well (Packaging People to Protect Products & People), such as when manufacturing potentially harmful drugs.

Contamination is any material, substance or energy that is undesirable or adversely affects any part, component, assembly or other activity being undertaken. One major form of contamination in a cleanroom environment is people.

The greatest source of particulate matter is human skin while lesser sources of particulate matter derive from equipment, the workplace, tooling and the room itself. Humans shed approximately 40-50 thousand skin cells each day. This shedding takes the form of loose skin flakes detaching themselves from the body and floating off into the atmosphere. Humans also cast off make-up particulates in the form of face powder (0.5-10 micron), hair (10 microns) and even bacteria (ranging from 0.3 to a few tenths). However, not all particulates enters the cleanroom via skin; some contamination is transported by air, water, chemicals, gases, surfaces, packaging and clothing.

Yes, we have sterilisation capabilities. At CRG we find that ETO is the best method for sterilising Polyester. Autoclaving causes these materials to shrink or melt, and gamma causes cross-linking in the polymers, leading to brittleness and reduced lifespan.

Sterilisation is done in-house and our method is revalidated annually using an 'overkill' method. It involves loading a steriliser chamber with garments, placing biological indicators in multiple locations (cold spots) and running a half length cycle. The method is in accordance with the Australian Therapeutic Goods Administration (TGA) good manufacturing practices.

ETO sterilisation is carried out with ethylene oxide (ETO) gas. Gas sterilisation by ETO requires penetration of the chemical agent and also of water vapour, which is essential for biocidal action. ETO is very diffusable, passing through many materials.

Yes! CRG's vendor management system can save you up to half a million dollars over 5 years! Sharpening your competitive edge through CRG's Vendor Management can reduce costs, free up resources and improve current processes, with results that meet both long-term and short-term goals.

CRG's VMI service delivers inventory management and control capabilities, providing you with access from your site to the same tools we use to run our distribution business. Our vendor managed solution helps ensure that your organisation runs more efficiently, more economically and, ultimately, more profitably.

CRG can also use their experience to recommend substitution products where appropriate in order to improve quality and/or reduce costs. Be sure you're using the highest quality and best value-for-money products.

Yes, it can. Unsealed stitched seams and fasteners such as Velcro or conventional zips offer little resistance to either airflow or aerosol penetration. In many garments, the air permeability of seams and fasteners is much greater than that of the fabrics. Consequently, although the area of seam and fastener is typically less than 1% of the total area of a garment, the total flow of contaminated air through seams and fasteners can be much greater than that through the fabric, particularly if the fabric is relatively impermeable to air.

Clean Room Garments manufactures its garment seams to exacting standards to help prevent this happening. Seams are 'French Seam' stitched; the seams are overlocked, stitched again to encase the overlock, then stitched down onto the garment.

The paper is autoclavable but it will take up some of the moisture from the steam and can curl very slightly. This is unavoidable with any cellulose based material and we don't have an alternative.

While the WWBKT is autoclavable (121c for up to 30 minutes), the casters for the bucket (WWCST) are not.

The CRGM0670 wipes Sterility Assurance Level (SAL) is 10 to the minus 6.

The SV-1 and SV-2 could be used for this application.

Yes.

No.

The whole system is autoclavable. Standard is 120 degrees C for 30 minutes.

Dycem suggest that the customer should use 20 parts warm water to 1 part Dyclean. The length of time a bottle of Dyclean will last for depends on how often the mat is cleaned and this depends on the environment in which the Protectamat is placed in, the traffic and your own cleaning policies. Options for cleaning frequency are: between breaks ' critical areas, daily, every second day and weekly.

Yes, the SV-1 and SV-2 are the same as SP-3 and SP-1, however, the SV are processed further to reduce the TOC levels. We would not recommend using the SP swabs for validation as they are not as clean as the SV.

The QuickConnect Mop handles are interchangeable with the Vertikleen (VKMOP) and Edgeless (s12) mops. However, they are not interchangeable with Wall Wipr (WWC14).

If you order a stock item before 5pm it will dispatched from our warehouse the next working day.

These products should be diluted with water of a suitable quality for a cleanroom environment. The water selection is generally one of the following:

De-ionised, Purified, Sterile, Water for Injection. Standard tap water is unlikely to be suitable for cleanroom use and not recommended.
