The first thing to note is that the term “HF” is used, and misused, Respirex does not make disposable work wear, only limited life Gas- to mean a number of different things. The nomenclature in this area Tight suits for emergency teams where decontamination of a suit is not standard and there is often some overlap in meanings. If you after use may not always be practicable. Our workwear is designed are not certain then there is no shame in clarifying or confirming the to be laundered and re-used, and will provide a lower lifetime cost meaning of a term. of ownership than the equivalent number of disposable garments, but there are a number of other advantages: HF itself stands for hydrogen fluoride. This is a molecule consisting of one atom of hydrogen attached to one atom of fluorine. This Reusable Garments Disposable Garments chemical boils at around 19 Celsius, just below room temperature; it is therefore normally a gas. However, if you cool HF slightly, or Reusable garments cost but Lower purchase cost, but single keep it under a slight pressure, it is a liquid. If you then spill the liquid offer a long shelf life use only in an environment at room temperature it will boil, but it takes quite a while for it all to boil away. Both the liquid and gaseous forms are Can be repaired to further Single use, not suitable for pure hydrogen fluoride with nothing added - no water solutions - so extend their shelf life repair they are both termed “anhydrous” (meaning “without water”). So far Stronger fabrics which are Weaker fabrics which tear and we have: tear resistant and do not puncture more easily puncture easily • Anhydrous hydrogen fluoride (or HF) gas • Anhydrous hydrogen fluoride liquid Reinforced cuffs and elbows Single layer, thinner fabrics to prevent abrasion (optional which abrade more easily If you ask about the concentration of the anhydrous liquid you will on some items) get a confusing answer. It is a pure liquid (like water or methanol) and Rubber cuffs and locking Lower specification elasticated so it is “neat” or 100%. Unfortunately you’ll come across “100%” in cuff systems preventing any or taped sleeves with greater another context in a minute. One last thing, pure hydrogen fluoride ingress up the sleeve risk of chemical ingress itself (either gas or liquid) is not at all acidic - strange but true. Glove changing quick and Glove changing more hazardous Anhydrous hydrogen fluoride (we could be talking about liquid or fuss free with elasticated sleeve and more gas here) is very soluble in water. You can dissolve 48g of pure complicated with taped option hydrogen fluoride in 100ml water (not a perfectly true statement, Heavy duty nylon zip Lightweight nylon zip but you don’t need to worry about that) The concentration of this solution is therefore 48%. This is the maximum concentration for pure hydrogen fluoride in water. This solution is moderately acidic Zip and Zip-flap and fumes a bit. It goes under a variety of names: Respirex Suits and jackets include a durable heavy duty • Hydrofluoric acid zip with a wide external flap • HF acid secured with Velcro that covers • 48% HF the teeth of the zip. A second • 50% HF (it gets rounded-up in some places) wide internal flap provides and additional layer of protection. If you adulterate your 48% solution with things like potassium This combination provides a fluoride you find that you then actually get more hydrogen fluoride liquid-tight seal without the to dissolve. In the end you’ll find that you can get 72g of hydrogen inconvenience of having to tape fluoride in 100ml impure water. This solution is also moderately the external flap shut. acidic and fumes quite a lot. It is known variously as:

• Hydrofluoric acid Soft cuff and cone • HF acid This sleeve cuff features a rigid retaining ring with an internal • 72% HF O-ring seal and a soft rubber external seal. The glove is stretched • 100% HF over a cone and is then pushed firmly into the cuff from inside the sleeve, providing a liquid-tight seal. - This is where some confusion sets in. Some people call this solution “100%” because it is the maximum concentration possible. Very misleading, but then so are a lot of industrial terms. If in doubt, ask.

So to summarize, we have HF in the following forms:

• Pure gas • Pure liquid • Pure acidic solution • Stronger impure acidic solution 10 www.respirexinternational.com Material Selection Training, Certification and Maintenance

The choice of material will determine both the likely life-span However good the protective equipment chosen for your site, if is of the garment, its operator comfort and the degree of chemical not worn correctly or properly maintained, there will be a risk to protection it can provide. For HF refinery applications Respirex the user. To ensure that employers can be confident that they have recommend neoprene for workwear applications, as it offers greater met their health and safety commitments, Respirex offer a range of chemical protection than PVC and is more flexible, making it more training courses of the correct use and maintenance of protective comfortable for the user. It is important to remember that these garments, and issue certificates to those attending. garments are the routine uniform for the site - they have got to be more than just “wearable”. We are also able to advise on risk assessment, and best practice for keeping for testing and maintenance records. A repair service is For workwear and air-supplied suits neoprene has sufficient also available, as are a range of spares and consumables. permeation resistance to anhydrous HF to get you out of danger. For workwear there is no benefit in choosing fabrics like ® Viton / Combining correct usage and inspection with scheduled servicing Butyl/Viton®; the level of protection offered by the garment design and repairs ensures user safety and will greatly extend the service doesn’t warrant such high permeation resistance. If the environment life of your equipment. is sufficiently hazardous that you need hours of protection against HF gas you will certainly need gas-tight seams, gas-tight foot-wear options and gas-tight seals everywhere.

However, for the gas-tight suit scenario, where you have accepted that the environment warrants the use of a gas tight suit, you do need the superior permeation resistance of either VBV or a similar fabric. The good news is that the design of this suit does warrant this extra resistance.

Chemical Permeation

Chemical ingress through protective workwear can occur through permeation or penetration. Permeation is a complex diffusion process causing degradation of the fabric. It involves molecular diffusion of the chemical through the fabric and does not involve holes in the fabric. Diffusion may also cause degradation of the fabric.

Penetration is chemical ingress through holes in the fabric. Ingress on a non-molecular level through holes in the fabric; stitch-holes; pores, seams; cuffs; zips; leg endings; collar etc.

Respirex provide permeation data for the fabrics used in our suits and continually test both fabrics and seams during production. The permeation test carried out by our laboratory is under total immersion conditions - continuous contact with the chemical. Although this is the recognized standard for testing, it is not always reflective of a typical spillage on site. The test models continuous- wear conditions as opposed to emergency protection.

Permeation data is available on request - please contact our US distributor on 281-350-5001, or by email at [email protected]
