Congratulations on your purchase of a Labconco Protector® PVC Perchloric Acid

Laboratory Fume Hood or Protector® PVC Acid Digestion Laboratory Hood.

The difference between the two hoods is that the Protector PVC Perchloric Acid

Hood uses a glass sash and the Protector PVC Acid Digestion Hood uses a

Lexan™ sash to combat the fogging of glass caused by hydrofluoric acid (HF).

Note that Perchloric acid will react with the Lexan sash and is not to be used in an

Acid Digestion Hood. The Protector PVC Perchloric Laboratory Hood is designed to efficiently ventilate procedures using Perchloric acid. The Protector

PVC Acid Digestion Laboratory Hood is designed to efficiently ventilate all other heavy acid operations including hydrofluoric acid. It is the result of Labconco’s more than 50 years experience in manufacturing fume hoods, and users like you suggested many of its features to us.

The Protector PVC Perchloric Acid Fume Hood has been engineered to provide maximum safety in a laboratory while using Perchloric acid. Usage of materials

other than Perchloric acid is not recommended. Perchloric acid is a strong oxidizing agent, and should not be used in combination with any organic material as the possibility of a hazardous chemical reaction or explosion

could develop. The Protector PVC Acid Digestion Fume Hood has been designed to handle all other types of acids including hydrofluoric acid (HF), but not Perchloric acid. The Protector PVC Hoods offer many unique features to enhance safety, performance, and visibility.

To take full advantage of them, please acquaint yourself with this manual and keep it handy for future reference. If you are unfamiliar with how fume hoods operate, please review Chapter 4: Performance Features and Safety Precautions before you begin working in the fume hood. Even if you are an experienced fume hood user, please review Chapter 5: Using The Protector PVC, which describes the Protector PVC Perchloric Acid Hood features so that you can use the hood efficiently.

Connecting to the Hood Exhaust System

!

WARNING: The weight of the exhaust ductwork system must be supported independently of the hood superstructure. Do not allow this weight to be supported by the hood structure as damage to the hood may occur.

AVERTISSEMENT : Le poids du système d'aspiration de ductwork doit être soutenu d'une manière indépendante de la superstructure de la hotte. Au cas où ce poids est supporté par la structure de la hotte, des dommages à la hotte peuvent arriver.

!

The exhaust connection should be installed by a qualified

HVAC contractor. The exhaust connection on your hood is

manufactured with 12" PVC nominal pipe (12.75" OD) to allow for minimum static pressure loss with proper transport velocities away from the hood. Consult Labconco Customer

Service should you require help sizing your blower for the exhaust volume and total system static pressure loss.

La connexion d'échappement devrait être installée par un professionnel de CVC agrée. La connexion d'aspiration sur votre hotte a été conçue pour un tuyau nominal de 12 pouces

(12,75 pouces de diamètre externe) afin d’avoir une perte minimale de pression statique avec les correctes flux de transport loin de la hotte. Consulter le Service Clientèle de

Labconco si la calibration de votre soufflerie pour le volume d'aspiration et la perte de pression statique du système le requiert.

The selected exhaust duct material must be fabricated out of type 1 unplasticized polyvinyl chloride or type 316 stainless steel material. The duct should be fully welded in the case of the stainless steel material or solvent bonded in the case of polyvinyl chloride so that it does not have any cracks or holes where Perchloric acid salts or acids can collect.

Le matériau conduit d'évacuation sélectionné doit être fabriquée sur une polychlorure de vinyle non plastifié de type

316 ou un matériau en acier inoxydable de type. Le conduit doit

être entièrement soudé dans le cas de l'acier inoxydable ou du solvant collé dans le cas du polychlorure de vinyle pour qu'il ne possède pas de fissures ou de trous, où les sels de l'acide perchlorique ou des acides peuvent s'accumuler.

Chapter 3: Getting Started

The exhaust duct system for a PVC Fume Hood should be run

in a vertical position and feature horizontal runs only where it

cannot be avoided. Should a horizontal run be a part of your

exhaust system, it should be sloped downward toward the hood

to prevent the pooling of the washdown water and perchloric acid salts or acids in the duct.

Le système de conduits d'échappement pour un PVC Hotte doit

être exécuté dans une position verticale et horizontale fonctionnalité fonctionne uniquement lorsque cela ne peut être

évité. Si une course horizontale être une partie de votre système d'échappement, il devrait être en pente descendante vers le capot pour empêcher la mise en commun de l'eau de lavage à grande eau et les sels de l'acide perchlorique ou acides dans le conduit.

CAUTION: PVC Fume Hoods must never be manifolded into a

common exhaust system. They require a dedicated exhaust system.

ATTENTION: PVC hottes ne doivent jamais être un tuyau collecteur dans un système d'échappement commun. Ils exigent un système d'échappement spécifique.

Connecting to the Exhaust Washdown

The entire exhaust duct system must have an adequate washdown system. This includes the exhaust ductwork located between the exhaust blower and the hood structure, the exhaust blower, and any ductwork located on the outlet side of the blower. Wash rings are recommended to be placed in the exhaust duct system approximately every 8 to 10 feet and after every change in direction to provide an adequate washdown. A drain should be provided in your exhaust blower and this washdown water and effluent material can be drained from the exhaust blower back directly into the exhaust duct for disposal. The PVC Hood was designed with an auxiliary port plugged at the factory, and it is to be connected to the washdown valve system to provide water to the wash rings. The plug is located on top of the hood near the first washdown nozzle. Plumb from the plugged connector with a

3/8" rigid polyethylene, copper, or stainless steel line.

Connecting to the Washdown Drain

The Protector PVC Hood has been supplied with a 2" nominal (2.375" OD) PVC pipe drain. Connect the 2" pipe to your floor drain. Be sure the connection is either fully solvent bonded or leak tight. See Figure 3-2.

Certifying the Protector PVC Fume Hood

The combination of your laboratory hood, exhaust ductwork, and exhaust blower gives you the flexibility to change the airflow at the sash opening of your hood.

To determine the actual face velocity at the sash opening, airflow velocity readings will need to be taken. This should be done across the sash opening of the hood in accordance with the Industrial Ventilation Manual section on laboratory hoods

(see Appendix E: References). Labconco recommends an average face velocity at the sash opening of 100 feet per minute. Consult Chapter 2 for proper airflow volumes for your particular model.

Your Protector Fume Hood has been tested at the factory per ASHRAE 110-1995.

All hoods achieve an “as manufactured rating” of less than 0.05 part per million

(ppm) at 4 liters per minute (lpm); AM<0.05 (consult Labconco for individual fume hood ratings). For “field use” ASHRAE testing contact Labconco Sales

Engineering Team or Customer Service for a certified on-site contractor.

Performance Features

Your Protector PVC Perchloric Acid Fume Hood has been engineered to efficiently ventilate and remove Perchloric acid fumes. The Protector PVC Acid

Digestion Fume Hood has been engineered to efficiently ventilate and remove acid fumes of all kinds (excluding Perchloric acid) including hydrofluoric acid (HF).

The Protector PVC Acid Digestion Hood must not be used with Perchloric acid as it can react with the Lexan sash. The Protector PVC Fume Hoods are designed to provide a flow of air sufficient to extract the acid fumes from within the work area and keep them away from the operator to avoid ingestion, inhalation, or skin contact.

The hood interior is constructed of seamless PVC with coved interior corners. The hood also features an integral washdown system, which helps prevent the accumulation of perchlorates or acids. The smooth interior finish compliments the washdown system as there are no screws or hollow fasteners present that could harbor undesirable residue.

The Protector PVC Fume Hood has been engineered to allow you, the customer, the maximum work area and personnel safety. The by-pass air configuration on the Protector PVC Fume Hoods is totally dependent on air being supplied to the hood from its surrounding environment for proper operation.

As stated previously, the Protector PVC Perchloric Acid Hood is designed to handle Perchloric acid operations of all types, while the PVC Acid Digestion Hood is designed to handle acids of all kinds (excluding Perchloric acid) including hydrofluoric acid (HF). Usage of materials other than the specific acids mentioned above is not recommended. Perchloric acid is a strong oxidizing agent, and should not be used in combination with any organic material as the possibility of a hazardous chemical reaction or explosion could develop.

Chapter 4: Performance Features & Safety Precautions

The integral washdown system in either PVC Fume Hood allows the operator the ability to wash behind the baffle and ensure that a build-up of Perchloric salts or other acids does not develop in that location. All of the washdown water from the internal spray nozzles is contained behind the baffle and does not interfere with normal operations being performed inside the hood. The washdown water is collected in the hood drain trough.

The hood liner must be washed down manually by the operator. The internal washdown system can be connected to the wash rings used in your hood exhaust system. The water used in the spray wash rings is collected in the hood drain trough once it has been allowed to flow down and cleanse the duct thoroughly.

!

WARNING: It is recommended that the PVC Hood be washed

down thoroughly after every usage for 10 minutes, at least once

a day.

AVERTISSEMENT: Il est recommandé que le capot PVC être lavé soigneusement après chaque usage pendant 10 minutes, au moins une fois par jour.

Operating the Vertical-Rising Glass Sash

Because of the Protector PVC Perchloric Acid Hood’s counterbalanced sash mechanism, it will take only a few pounds of force to move the sash up or down, and you can operate the sash smoothly with one or two hands positioned any where along the handle. The glass sash is suitable for use with Perchloric acid.

The vertical-rising sash may be raised to a maximum 28" operating height. The airflow requirements should be sized for the 28" operating height; if using sash stops then the airflow requirements can be reduced by approximately 40% at 18" or approximately 50% at 15".

Operating the Vertical-Rising Lexan Sash

Because of the Protector PVC Acid Digestion Hood counterbalanced sash mechanism, it will take only a few pounds of force to move the sash up or down, and you can operate the sash smoothly with one or two hands positioned any where along the handle. The Lexan sash prevents fogging caused by hydrofluoric acid (HF). The Lexan sash is suitable for acids other than Perchloric acid, which can react with the Lexan plastic. The airflow requirements should be sized for the

28" operating height, if using sash stops then the airflow requirements can be reduced by approximately 40% at 18" or approximately 50% at 15".

Operating the Blower

Your Protector PVC Fume Hood utilizes a remote style blower, which can be activated by turning the blower switch to “ON.” You can validate the hood performance by watching smoke drawn into the hood face opening.

Chapter 5: Using the Protector PVC

Operating the Washdown Control Valve

Your Protector PVC Fume Hood has a washdown control valve located on the upper left-hand side that controls water to the washdown spray nozzles. The nozzles are located behind the hood baffle and will washdown areas in the hood, which are unaccessible without removing the baffle. The washdown control system can also be set up to control the washdown rings used in your exhaust ductwork. This is done by connecting the water line to the plugged connection on top of the washdown hood system or ordering additional washdown valves found in Chapter 2 and Chapter 7.

Working in Your Protector PVC Fume Hood

Planning

• Thoroughly understand procedures and equipment required before beginning work.

• Arrange for minimal disruptions, such as room traffic or entry into the room while the hood is in use.

Start-up

• Turn on fluorescent light and hood blower.

• Slowly raise the sash.

• Check the baffle air slots for obstructions.

• Allow the hood to operate unobstructed for 5 minutes.

• Wear a long sleeved lab coat and rubber gloves. Use protective eyewear.

Wear a protective mask if appropriate.

Loading Materials and Equipment

• Only load the PVC Hood materials required for the procedure. Do not overload the hood. Only use Perchloric acid in the PVC Perchloric Acid

Fume Hood.

• Radioisotope materials are not recommended for use in these PVC Hoods.

Consult your Safety Officer should you have any questions.

• Do not obstruct the front air foil, or rear baffle slots.

• Large objects should not be placed close together and spaced above the liner bottom to permit airflow to sweep under the equipment.

• After loading the hood, wait one minute to purge airborne contaminants from the work area.

Work Techniques

• Keep all materials at least 6 inches inside of the sash, and perform all contaminated operations as far to the rear of the work area as possible.

Segregate all clean and contaminated materials in the work area.

• Avoid using techniques or procedures that disrupt the airflow patterns of the hood.

Final Purging

• Upon completion of work, the hood should be allowed to operate for two to three minutes undisturbed, to purge airborne contaminants from the work area before shutting down blower.

Product Service 1-800-522-7658 33

Original instructions

Chapter 5: Using the Protector PVC

Unloading Materials and Equipment

• Objects in contact with contaminated material should be surface decontaminated before removal from the hood.

• All open trays or containers should be covered before being removed from the hood.

Final Washdown Procedure

• Water washdown or flooding the surfaces with water is standard practice and results in reduction of contamination on the PVC liner material due to

Perchloric acid salts or acids.

• Proper operation of your PVC Fume Hood requires that you wash the fume removal system down sufficiently to ensure that there is no build up of

Perchloric acid salts or acids within the entire system.

• Normal washdown procedures suggest that you run the wash system in the exhaust duct with the fan on for approximately 1-2 minutes, and then with the fan off for approximately 10 minutes to thoroughly clean this portion of the exhaust system.

• In addition to this, the internal hood spray nozzles should be activated for approximately 10 minutes after the completion of your procedures to clean behind the baffle in the hood. Work areas in front of the baffle in the hood will need to be manually cleaned by the operator. Because the volume of

Perchloric acid salts or acids can vary greatly due to specific procedures and workloads, you should consult your in-house Safety Officer for specific rules and frequency requirements for washing down your total system.

Shutdown

• Only turn off the fluorescent light and hood blower if final washdown is complete, and then close the sash.
