Rev. B1.0 Scope

This document covers the process required to mix acids at MDTL for use in performing a Buffered Chemical Processing (5520-OP-333837) or an Electro-polishing (5520-OP-333841) or for any acid process that has hydrofluoric acid as one of its’ components. Note, that any acid mixing that has hydrofluoric acid (HF) as one of the acids must also have a specific Hazardous Analysis prepared and approved of before mixing the acids.

2.0 Safety Requirements

2.1 General Safety Overview Acid mixing cannot be done unless TWO PEOPLE are present in the wet chemistry area

at all times (see section 2.2). Acid mixing cannot be done without proper training and review of documentation (see

section 2.3). All persons performing acid mixing must have an understanding of the location of the

hood, safety shower, eye wash station, antidote, acid, phone, PPE and pH strips (see section 2.4).

Proper Personal Protective Equipment (PPE) must be worn (see section 2.5). It is important to avoid contact with any of the acids as they are very dangerous. All persons performing acid mixing must have a thorough understanding of the

emergency procedures (see section 2.6) and must have their own tube of calcium gluconate at home

2.2 Two -Man Rule During any Acid Mixing operation 2 people will be needed during the entire operation. Two people will be inside the wet chemistry area. The two people inside the wet chemistry area will be directly involved with the mixing process. One person inside the wet chemistry area will bring various non-hazardous materials needed to the wet chemistry area, will stop people from entering 36A Neuqua, and should call 3131 and 3232 during an emergency.

The Lead person performing an Acid Mixing operation shall have one person to assist during any mixing process. The job of the second person is to assist the Lead person by removing used beakers and by monitoring all actions taken to ensure no acid contacts the Lead person. In case of exposure with the acid, the job of the non-exposed person is to assist the exposed person. Once the person affected is rinsing/showering, the second person should leave the wet chemistry area and should call 3131 and 3232 to inform emergency personnel and medical of the exposure. This is an emergency.

Note: The shower/eyewash next to Hood #1 is connected FIRUS system and once triggered will notify the Communications Center of an HF acid exposure.

2.3 Training & Documentation The people in the wet chemistry area performing acid mixing and any other people outside the wet chemistry area must be informed of all applicable FESHM chapters, TD and MDTL safety policies/procedures, and the associated Safety Data Sheets (SDS). The appendices contain reference SDSs for nitric, phosphoric, sulfuric and hydrofluoric acid used in this procedure. In addition, SDSs can also by found on-line in the Fermilab ESH&Q, database 1. Applicable FESHM chapters and TD policies include:

FESHM 5051 Hazard Communication; FESHM 5100 PPE; FESHM 8000 Environmental Protection; FESHM 8021 Chemical and Radioactive Waste Management FESHM 8025 Wastewater Discharges to Sanitary Sewers FESHM 8030 Spills and Releases; TD Chemical Hygiene Plan

Any person performing acid mixing must also fulfill the following requirements: Read and understand the hydrofluoric acid first aid instructions;

Complete the Acid Mixing Training (on-the-job): TD000011-01-OJ

2.4 Understanding of Area All safety signs in the hood area must also be read. The antidote for hydrofluoric acid exposure, calcium gluconate jelly, must be close to the area where the acid is being handled. The expiration date of the calcium gluconate must be checked each time before acid mixing is performed to see if it is still good. A discussion about how to respond to an emergency during mixing shall be done prior to any work, every time hydrofluoric acid or a BCP/EP solution is being used. Make a note as to where acid absorbent material is kept in case of an acid spill. Notice where the safety shower/eye wash is located. Notice where the phone is located. Notice where the pH strips are stored as they must be used to check the acidity of any spill.

2.5 Personal Protective Equipment (PPE) Protective garments must be worn to cover almost every area where acid could contact a worker when working with acids during the acid mixing process. This includes goggles, face shield, gloves, boots, and a body suit. The currently approved garments are listed below.

For Workers in the Wet Chemistry Area:

Item Requirements PictureCoveralls 1. Cover the body from the neck to the ankles,

excluding the hands.2. Hydrofluoric acid resistant;3. Made of Tyvek/Saranex SL or other material

capable of withstanding hydrofluoric acid for GREATER than 480 minutes;

4. Have elastic at both the wrists and ankles, or if there is no elastic the wrists and ankles must be taped tightly.

1

Goggles/Face shield 1. Cover the face and head;2. Chemical goggles (Uvex # S3960C or equivalent);3. Face shield equipped with a polycarbonate window,

crown protector and headgear.

The face shield and goggles are not meant to be acid resistant but are meant to protect from acid splashes.

2

Gloves 1. Two pair of gloves are to be worn;2. Outer-gloves shall be Ansell Edmont, Embossed

Grip, 17 mil thick Neoprene glove (Part #8159-8 from Lab Safety Supplies). NOTE: the requirement is capability of withstanding 2 hours of submersion in hydrofluoric acid, as well as having an embossed grip;

3. A second pair of gloves that have at least minimal acid resistance must be worn under the outer gloves.

4. Gloves are to be inspected prior to each use (see statement below).

3

Boots 1. Footwear shall consist of knee-boots made of Superpoly (urethane/vinyl compound) or other material rated with a high degree of resistance to

3



Rev. Bacids, oils, and other chemicals;

2. Minimum of 14 inches high to cover the ankles and part of the shin area.

For temporary use only (1 or 2 times until boots are ordered) an acid resistant spat that covers the top of the foot may be worn over the shoes.

For Workers Outside the Wet Chemistry Area: The PPE for others workers in the area is a lab coat and eye-protection..

When putting on the protective garments, the elastic of the coveralls shall cover the gloves up to the wrists and on the ankles it shall cover over the top of the knee-boot down at the ankle. This is to prevent any acid spills from touching the skin.

Gloves shall be inspected for tears or punctures and tested before each use. Each glove shall be tested by inflating with air and then tying off the wrist area and then submerging the glove into a container of standing water. If any air bubbles are detected, dispose of the gloves and test a new pair. Even new gloves must be inspected and tested before using.

Caution must be taken not to overheat while wearing the Tyvek/Saranex SL coveralls. The temperature of the lab must remain cool when wearing the coveralls. Frequent breaks should be taken to avoid overheating. If the person does not feel well the person should stop the acid mixing procedure and should seek medical help as they may be developing heat exhaustion or heat stroke.

2.6 Emergency Procedures

2.6.1 ExposurePREVENTION of exposure or injury is always the primary goal when working with acids. Every effort must be made to prevent exposure to HF. Speed is of the essence when an exposure to HF occurs. If at any time during the mixing process it is believed that hydrofluoric acid or the BCP/EP solution has come in contact with an unprotected portion of the body, the following must be done immediately:

2.6.1.1 Skin Contact1. Immediately start flushing the area with water and flush for 5

minutes. 2. All contaminated clothing must be removed while rinsing with water.3. As soon as the exposure occurs the person outside the wet chemistry

area must call 3131 and inform emergency personnel of the exposure. 4. A second call must then be made to medical at 3232 to alert medical

personnel of the HF/BCP/EP acid exposure.5. At the end of five minutes of flushing the area if medical assistance is

not on hand to advise, begin applying the 2.5% USP calcium gluconate to the affected area immediately. Disposable rubber gloves should be worn during the treatment to eliminate the possibility of



Rev. Breceiving a secondary burn. Liberal quantities of the calcium gluconate gel must be massaged into the burned area continuously for up to several hours. Relief of pain is an indicator of the efficiency of the antidote.

2.6.1.2 Eye Contact1. Flush the eyes and surrounding skin with water or use an Emergency

Eyewash solution that contains calcium gluconate USP 1% w/w.. The eye lids should be lifted out so that the water can flush out that area. Continue rinsing the eyes from the time of the exposure until the Fermilab fire department arrives. The fire department should continue to flush the eyes until treatment can be performed at the emergency room.

2. All contaminated clothing must be removed and isolated while rinsing with water.

3. As soon as the exposure occurs the second person must call 3131 and inform emergency personnel of the HF/BCP/EP exposure.

4. A second call must then be made to medical at 3232 to alert medical personnel of the HF/BCP/EP acid exposure.

5. When emergency personnel arrive they must be alerted to the fact that it is an eye exposure and that the eyes should be flushed continuously with normal saline solution or an Emergency Eyewash solution containing calcium gluconate during transportation to the emergency room.

2.6.1.3 InhalationDo not put yourself into a dangerous situation by entering an area that has high levels of HF acid vapor2. The portable and wall mounted HF acid vapor detectors should be used to check the HF acid vapor level in the area.

The wall mounted detector is set to alarm at 0.5 ppm. If the wall detector alarms, then immediately stop all work and do the following:

If the HF acid vapor level is at 0.5 ppm and below 1.0 ppm:

1. Immediately move the victim to fresh air.2. From a safe location have someone call emergency at 3131 to notify

them of high HF/BCP/EP vapor levels.3. A second call must then be made to medical at 3232 to alert medical

personnel of the exposure to high vapor levels of HF/BCP/EP.4. Keep the victim warm and comfortable until help arrives.5. The victim should be administered 100% oxygen as soon as possible.

If the HF acid vapor level is below 2.0 ppm:

1. Immediately move the victim to fresh air.2. From a safe location have someone call emergency at 3131.3. A second call must then be made to medical at 3232 to alert medical

personnel of the exposure to high vapor levels of HF/BCP/EP.4. Keep the victim warm and comfortable until help arrives.5. The victim should be administered 100% oxygen as soon as possible.6. If the vapor level is below 2.0 PPM, personnel with HF worker PPE

can work to identify and mitigate the source of the vapor. The total duration spent in the HF vapor environment is not to exceed 60 minutes (see also the emergency response procedures OP-333846).

7. If the vapor level remains below 1 PPM, it is not necessary to immediately evacuate MDTL.

2 Refer to the NIOSH pocket guide more details: http://www.cdc.gov/niosh/npg/npgd0334.html


http://www.cdc.gov/niosh/npg/npgd0334.html


Rev. B

If the vapor level is above 2 PPM but below 9 PPM (the maximum detected on our portable and fixed gas monitors):

1. Evacuate the area.2. Immediately move the victim to fresh air.3. From a safe location have someone call emergency personnel at

extension 3131 to notify them of the exposure to high vapor level of HF/BCP/EP.

4. A second call must be made to medical personnel at extension 3232 to alert them of the exposure to high vapor levels of HF/BCP/EP.

Note:1. Guidelines for HF inhalation are based on a 2.0 PPM HF TLV-C

(Threshold Limit Value-Ceiling) or 1.7 mg/m3 recommendation by the American Conference of Governmental Industrial Hygienists (ACGIH).

2. Acute Exposure Guideline Levels (AEGLs) issued by EPA National Advisory Committee classifies HF gas as a nondisabling exposure of

3. 1 ppm (0.8 mg/m3) for a 60-Minute exposure.

2.6.1.4 Ingestion1. Have the victim drink 1-2 glasses of water as quickly as possible to

dilute the acid. Do not induce vomiting. Do not give emetics or baking soda. Never give anything by mouth to an unconscious person.

2. Give several glasses of milk or several ounces of milk of magnesia, Mylanta, Maalox, or grind up and administer up to 30 Tums, Caltrate or other antacid tablets with water.

3. As soon as the exposure occurs the person not exposed must call 3131 to notify emergency personnel of the exposure.

4. A second call must then be made to medical at 3232 to alert medical personnel of the HF/BCP/EP acid ingestion and to obtain his advice.

Any contaminated clothing must be carefully collected by someone wearing the same PPE as worn by the acid worker. The clothing should then be put into a heavy plastic bag. The bag must then be labeled as being contaminated by hydrofluoric acid/ BCP/ EP solution and given to the local waste coordinator (NOTE: this is the local “waste generator” in our ESH&Q terminology) for proper disposal.

2.6.2 Emergency Shutdown ProcedureWhile mixing acids, if electrical power is lost, a tornado warning occurs, or a fire alarm goes off, stop mixing and close the hood sash completely. Wait until power is restored or the all clear signal is given before mixing is resumed.

2.6.3 Water supplyIf there is low water pressure or no water then the mixing process must be postponed until the eyewash and shower are in working condition.

3.0 Preparation of Acid Solutions

General Notes Hydrofluoric acid work shall be limited to a maximum of 5 liters of mixed acid, for any acid process at MDTL with a limit of 40 liters per month. All hydrofluoric acid used will be recorded in the HA documentation.



Rev. BThe hydrofluoric acid purchased for acid work will be limited to a maximum size of 500 mL bottles, due to the hazards involved in handling this acid. The nitric acid, sulfuric acid and phosphoric acid will be limited to a maximum size of 2 ½ liter bottles.

An acid carrier will be used when transporting the bottles within the wet-chemistry area. In the hood, an appropriate secondary containment should be used at all times.

All acid handling steps are to be performed under an operating ventilation hood located next to the emergency eyewash and shower. Acid resistant PPE must be used and shall completely cover all exposed skin. The proper PPE is described above in Section 2.5.

The “WARNING, DO NOT enter” light that is at the entrance to the MDTL from the office area must be turned on. There is also an audible alarm system, which will trigger whenever the door is opened.

All appropriate PPE must be worn during the process. Gloves must be kept dry at all times when working with acids. If gloves become wet due to handling ice or water, dry them completely before resuming the etching. If at any time you notice a drop of water or suspect acid on the gloves, immediately rinse gloves thoroughly and then dry them. For long etch procedures (> 20 min.) repeatedly rinse and dry gloves completely throughout the mixing process, so as to remove any acid which is not seen by the “naked” eye and to maintain good integrity of the gloves.

Preparation for Mixing at MDTL Test the eyewash station. Do not test the safety shower. The safety shower is equipped with a FIRUS system that calls the communication center and dispatches emergency personnel. The safety shower and FIRUS system will be tested once a month. Put on appropriate PPE as shown in Section 2.5.

3.1 Materials All hazardous mixtures of acids must be prepared in hood #1. Specific details about chemical storage are given below. The following materials are needed for mixing acids:

Qty./Amount Item DescriptionPlan ahead as volumes

varyAcids needed: For E. P.: Refrigerated Sulfuric Acid (H2SO4) and Hydrofluoric Acid (HF) in ½ to 2 liter PFA bottle. This depends upon final quantity of acid needed.For BCP: Phosphoric acid (H3PO4), Nitric acid (HNO3), and HydrofluoricAcid (HF).Additionally a Nalgene LDPE or a PFA bottle may be used for storing mixed acids until they can be used.

3.2 Process for Mixing Acids for Electro-polishing

1. Mixing HF and H2SO4 is a very exothermic process, especially at the beginning of the process. To reduce the possibility of a reaction, one should work with these acids refrigerated.

2. Prepare a PVDF, PFA or HDPE bottle for the mixed acid storage by affixing an appropriate label indicating the contents as well as the mixing date on it. A Black Sharpie can also be used to write on the bottle its contents and the date mixed.

3. The acid ratio of HF to H2SO4 that is currently being used is 1:10. Due to the highly reactive nature of these acids always pour the measured amount of H2SO4 into the measured amount of HF. Always pour concentrated acid into the one with the most water. (Adding acid to water)

4. Retrieve the HF and H2SO4 from their storage area and sit them inside the hood. Make sure that each bottle of acid is sitting in a secondary containment.

5. Position ice bath/secondary containment container on a magnetic stirrer inside the hood and then add the aluminum grating. Add some water. Place the HD polyethylene pitcher on the grating inside the HD polyethylene bin and add the spin bar to the pitcher making sure it spins freely. The grating is optional and may not be needed for every process. This container will be where the acid will be poured for mixing.

6. Place an additional secondary containment in the hood near the ice bath/secondary containment. This is where the acid will be transferred from the bottle to a graduate for measurement purposes. Carefully pour the refrigerated HF acid from the bottle into a graduate for precise measuring.

7. Make sure that the acid doesn’t pour out too fast as it could splash outside of the beaker. When finished pouring, tighten the cap back onto the acid bottle and move the bottle so that it is away from the area where you are mixing the acids. This should be done after every pouring so that you reduce the possibility of spilling acid out of an overturned bottle. Turn on the magnetic stirrer and slowly increase its speed, making sure that the spin bar is slowly rotating properly.

8. Use a separate beaker for measuring the H2SO4. To safely measure the acid, pour it into a 1000 ml beaker and then pour from the beaker into the graduate. A large open-mouth graduate can also be used for measuring the acid.

9. Pour the measured amount of H2SO4 from the graduate into the HD polyethylene pitcher. Carefully drain the acid into the pitcher and then sit the used graduate aside, toward the back of the hood, out of the way.

10. Continue measuring and pouring the H2SO4 into the pitcher until the total amount of H2SO4 has been reached. Continue mixing for approximately 10 minutes until all acids have been mixed together thoroughly.



Rev. BNote: In the case of the “R&D” EP process, some other reactant might be added to

the mixture. The order of mixing of the additional chemicals should follow the usual safety procedures as recommended on the SDS. A Hazard Analysis mustMetallographic Solutions: The recipes for various metals and specific acid solutions can be found in the book: “Metallograpic Etching, 2nd Edition”.

11. If necessary, add ice to the ice bath container carefully shielding the acid with one hand, making sure no ice falls into the acid. Ice and more water may be needed in the ice bath so that a slurry of ice water fills the container up to the level of the acid.

12. If you are finished with mixing E.P. solution remove the spin bar using the retriever.

13. Transfer the acid solution to the prepared bottle using a funnel. This should be done by placing the Nalgene HDPE/LDPE bottle into a secondary containment, inserting the funnel into the bottle, and then carefully pouring the acid into the bottle. Make sure that the cap on the bottle is tightened when done. The prepared bottle should then be placed in an acid carrier if being transported more than 3 feet.

14. The mixed acid can now be safely stored in the acid carrier in a chemical refrigerator until needed.

3.3 Process for Mixing Acids for Buffered Chemical Polishing

1. Prepare a PVDF, PFA or HDPE bottle for the mixed acid storage by affixing an appropriate label indicating the contents as well as the mixing date on it. A Black Sharpie can also be used to write on the bottle it’s contents and the date mixed.

1. Retrieve the H3PO4, HNO3, and HF acids from their storage area and sit them inside the hood. Make sure that each bottle of acid is sitting in a secondary containment.

2. The acid ratio for mixing BCP is: 2 parts H3PO4, 1 part HNO3, and 1 part HF. Due to the highly reactive nature of these acids always pour the measured amount of HF first into the pitcher when mixing acids. Always pour concentrated acid into the one with the most water. (Adding acid to water).

3. As a larger volume of this acid mixture is used, you should limit the maximum volume mixed to 4 liters (4000 ml) per mixing process. If more acid is needed repeat the mixing process.

4. Position ice bath/secondary containment container on a magnetic stirrer inside the hood and then add the aluminum grating. Add some water. Place the HD polyethylene pitcher on the grating inside the HD polyethylene bin and add the spin bar to the pitcher. This container will be where the acid will be poured for mixing.

5. Place an additional secondary containment in the hood near the ice bath/secondary containment. This is where the acid will be transferred from the bottle to a graduate for measurement purposes. Carefully pour the hydrofluoric acid from the bottle into the graduate and then into the large beaker. Make sure that the acid doesn’t pour out too fast as it could splash outside of the beaker. When finished pouring, tighten the cap back onto the acid bottle and move the bottle so that it is away from the area where you are mixing the acids. This should be done after every pouring so that you reduce the possibility of spilling acid out of an overturned bottle.

6. Make sure that the spin bar is slowly rotating properly.

7. Continue measuring and pouring the HF into the pitcher until the total amount of HF needed has been reached.



Rev. B

8. Turn on the magnetic stirrer and slowly increase its speed, making sure that the spin bar is slowly rotating properly.

9. Each of these acids should have their own beaker for performing the required measurements.

10. Next, pour the nitric acid from the bottle into a beaker and then pour the acid into a graduate for measurement. Then pour the nitric acid into the HD polyethylene pitcher. Taking the same safety precautions as listed above.

11. Finally, pour the phosphoric acid from the bottle into a beaker and then into a graduate. Taking the same safety precautions as listed above.

12. If you are finished with mixing BCP solution remove the spin bar using the retriever.

13. Transfer the acid solution to the LDPE bottle using a funnel. This should be done by placing the LDPE bottle into a secondary containment, inserting the funnel into the bottle, and then carefully pouring the acid into the bottle. Make sure that the cap on the bottle is tightened. The LDPE bottle should then be placed into an acid carrier.

14. The mixed acid can now be safely stored in the acid carrier in a chemical refrigerator until needed.

4.0 Other Acids Mixed with HF

4.1 Other acid solutions can be prepared by following the mixing steps listed specifically for EP and BCP by following the same procedure. Always start mixing with the acid with the most water and then add the more concentrated acids. HF can also be added to a solvent to prepare a specific metallographic solution. Always add acid to water. Note: for metallographic solutions that require HF mixed with solvents they must be stored in a chemical refrigerator and should be used soon after mixing. Do not store these solutions more than a week as they can become unstable if a solvent is used.

4.2 A HA will need to be written and approved of for any new solutions you may need to prepare if they contain HF.

5.0 Post Mixing Cleanup

5.1 Cleaning of Containers Use standard laboratory procedures to clean all plastic containers. Use sodium bicarbonate and water to first rinse out all acid containers. Then use micro 90 as the detergent cleaner, rinse 3 times minimum with house water (after cleaning) and for the final rinse use distilled water. Dry thoroughly and put plastic ware away.

5.2 Cleaning the Hood Wipe down the sill of the hood using some of the detergent wash water. Use the pink WypAll X80 for all clean up. Note that if it changes to purple or black this indicates that the pH is less than 3 indicating that the area needs to be cleaned more thoroughly. The pink WypAll towels can also be used in the hood to sit acid contaminated utensils on, such at the spin bar retriever or the funnel. When finished thoroughly rinse the used pH indicators and any towels that have changed color before disposing of in the trash.

5.3 General For any empty acid bottles please see the waste coordinator (NOTE: this is the local “waste generator” in our ES&H terminology). Do not dispose of them into the trash. Return HF



Rev. Bantidote to storage. Return all containers used to their storage area. The warning light and audible system should now be deactivated, and normal occupation of the laboratory can resume.

6.0 Lock-Out and Tag-Out Procedures

No Lock-Out/Tag-Out Procedures apply.

7.0 Records

7.1 Acid Mixing Checklist A MDTL Acid Mixing Checklist 5520-FM-333838 is to be completed for every BCP/EP operation, and is typically completed the day before BCP/EP etching.
