Each perchloric acid fume hood shall have its own exhaust system. Perchloric acid hoods have washdown systems and either stainless steel or PVC liners to withstand acid exposure.
Perchloric Acid hoods are offered in sizes 48 60 72 widths and include a dedicated wash down and exhaust system.
Perchloric acid fume hood. Perchloric acid fume hoods should not be manifolded together. Spills of perchloric acid and spill clean-up materials must be immediately cleaned-up and prevented from drying out to avoid formation of perchlorate salts. On February 20 1947 in Los Angeles California 17 people were killed and 150 injured when a bath consisting of over 1000 liters of 75 perchloric acid and 25 acetic anhydride by volume exploded.
A coved stainless steel liner with integral work surface an internal water wash down system and water collection trough provide for detailed cleaning of the hood interior. They feature wash down systems integral work surfaces and drainage troughs so that they may be thoroughly rinsed after each use to prevent the accumulation of potentially reactive perchloric salts. Features All Models By-pass airflow design and by-pass block.
Outfitted with a one-piece T316 4 finish stainless steel liner and countertop with radius construction to contain spills. Perchloric Acid hoods are offered in sizes 48 60 72 widths and include a dedicated wash down and exhaust system. Perchloric acid fume hoods are single use hoods and should only be used for perchloric acid digestions.
Never heat perchloric acid in an oil bath or with an open flame. The traditional method exploits the high aqueous solubility of sodium perchlorate 209 g100 mL of water at room temperature. Based on the LA-series superstructure by iQ Labs this fume hood features a one-piece cove-cornered Type 316 stainless steel interior with integral work surface and washdown system.
The standard FHS series unit is capable of removing up to 99 of acidic contaminants up to 500 PPM. Box 1842 Statesville North Carolina 28687-1842 Phone 704-873-7202 IIH25-SA 1105-3. Storage and Waste disposal.
Perchloric Acid Hood LOCs Perchloric Acid Fume Hoods are specifically designed for the use of perchloric acid. Perchloric acid fume hoods should have shatterproof glass. Perchloric Acid Fume Hood The iQ Labs perchloric acid fume hood is designed specifically for procedures using this hazardous acid.
Perchloric acid is produced industrially by two routes. Installation Instructions Supreme Air Bench Hood Perchloric Acid Fume Hood wVertical Rising Sash Kewaunee Scientific Corporation PO. Perchloric Acid hoods are offered in sizes 48 60 72 widths and include a dedicated wash down and exhaust system.
Featuring washdown systems integral work surfaces and drainage troughs these benchtop PVC-lined hoods are designed specifically for procedures involving perchloric acid. Any heating of perchloric acid or 73 or greater concentrations require a special dedicated laboratory fume hood equipped with a wash down system. Perchloric Acid Fume Hood A perchloric acid hood has the general characteristics of a bench-top hood but the interior lining is coved and welded seamless stainless steel.
Perchloric Acid Fume Hood wVertical Rising Sash Figure 1 Detail 2A Figure 2 Detail 2B. Perchloric acid in industry and in fume hoods. Perchlorate salt formation is a significant concern in fume hood exhaust systems and is one of the reasons a design ated fume hood is required.
Additional Features Specifications. Series 700 Perchloric Acid fume hood models are constructed with a built-in trough to capture runoff in washdown procedures with a manual washdown feature for the areas behind the baffles as well as the duct-collar areas. UniFlow Perchloric Acid Fume Hoods - niFlow Perchloric Acid fume hoods feature a type 316 stainless steel one piece fume chamber with integral worksurface and are engineered for the safe handling of perchloric acids in laboratory procedures.
NaClO 4 HCl NaCl HClO 4. DO NOT perform perchloric acid digestions in a laboratory fume hood. Special applications require special fume hoods.
Acid digestion hoods have PVC liners and Lexan sashes to resist etching by hydrofluoric acid. In perchloric acid hood non-reactive and corrosion-resistant material is extended all the way through the exhaust system. Treatment of such solutions with hydrochloric acid gives perchloric acid precipitating solid sodium chloride.
The FHS series integrates a counter current scrubber with a traditional fumehood design to reduce space requirements eliminate the need for a remote scrubber and significantly reduce installation and maintenance costs. Perchloric acid has a brutal history of causing industrial accidents. UniFlow Perchloric Acid fume hoods feature a type 316 stainless steel one piece fume chamber with integral worksurface and are engineered for the safe handling of perchloric acids in laboratory procedures.
Use explosion proof electrical equipment. Perchloric acid hoods shall be prominently labeled Perchloric Acid Hood. Contact OHS for more information.
UniFlow Perchloric Acid fume hoods feature a type 316 stainless steel one piece fume chamber with integral worksurface and are engineered for the safe handling of perchloric acids in laboratory procedures. It is recommended to thoroughly wash down fume chamber and. Special Application Fume Hoods.
Protector Stainless Steel Perchloric Acid Fume Hoods are designed specifically for all procedures in the laboratory involving the use of perchloric acid. Procedures using concentrated perchloric acid 70 or heat any amount or concentration of perchloric acid must be performed in a closed system or within a specially designed perchloric acid fume hood with wash down systems to prevent the accumulation of explosive perchlorates in the hood and ducting. Floor-mounted hoods accommodate oversize apparatus.
Electric hot plates electrically or steam-heated sand baths heating mantles or steam baths are preferred. The OConnor Electro-Plating plant 25 other buildings and 40 automobiles were obliterated and 250 nearby homes were damaged.
