Section 2 – Type of SOP:

☐ Process ☒Hazardous Chemical ☐ Hazardous Class



Section 3 – Physical / Chemical Properties and Uses

Physical / Chemical Properties:

CAS#: 7738-94-5

GHS Classification: Carcinogen, Toxic, Oxidizer, Corrosive

Molecular Formula: H2CrO4

Form (physical state): Liquid

Color: Dark Red-Brown



Uses:

In the laboratory, Chromerge is used to oxidize organic compounds and clean glass wear.



Section 4 – Potential Hazards

Chromerge solution may cause cancer. May cause heritable genetic damage. Contact with combustible material may cause fire. Chromerge is toxic in contact with skin and if swallowed. Swallowing can cause severe burns of the mouth, throat, and stomach, and is potentially fatal. It is extremely destructive to the tissue of the mucous membranes and upper respiratory tract. Causes severe skin and eye burns. Symptoms of redness, pain, and severe burn as well as skin sensitization can occur. Eye contact may cause blurred vision, redness, pain, severe tissue burns, and permanent eye damage. Inhalation may cause severe irritation and pulmonary sensitization or allergic asthma. Repeated or prolonged exposure can cause ulceration and perforation of the nasal septum, respiratory irritation, liver and kidney damage and ulceration of the skin. Ulcerations at first may be painless, but may penetrate to the bone.



Potential Health Effects:

Inhalation: May cause irritation of the respiratory tract with burning pain in the nose and throat, coughing, wheezing, shortness of breath and pulmonary edema. May cause asthmatic attacks due to allergic sensitization of the respiratory tract.

Skin: Causes skin burns and irritation. May cause skin sensitization. May cause irritation with burning pain, itching and redness. May cause deep, penetrating ulcers of the skin. May be absorbed through damaged or abraded skin in harmful amounts. Chronic exposure to water insoluble hexavalent chromium compounds has been shown to be associated with lung cancer and gastrointestinal tract tumors.

Eyes: May cause irreversible eye injury. Contact with eyes may cause severe irritation, and possible eye burns.

Ingestion: May cause severe gastrointestinal tract irritation with nausea, vomiting and possible burns. May cause liver and kidney damage.

Section 5 – Personal Protective Equipment (PPE)

Respirator Protection:

Respirators should be used only under any of the following circumstances:



  • As a last line of defense (i.e., after engineering and administrative controls have been exhausted).

  • When Permissible Exposure Limit (PEL) has exceeded or when there is a possibility that PEL will be exceeded.

  • Regulations require the use of a respirator.

  • An employer requires the use of a respirator.

  • There is potential for harmful exposure due to an atmospheric contaminant (in the absence of PEL)

  • As PPE in the event of a chemical spill clean-up process

  • Lab personnel intending to use/wear a respirator mask must be trained and fit-tested. This is a regulatory requirement. Contact EH&S 8-8411 regarding respirator clearance.

Hand Protection:

Gloves must be worn. Use proper glove removal technique to avoid any skin contact. Nitrile gloves are recommended. Check the resources below for the most suitable glove.



NOTE: Consult with your preferred glove manufacturer to ensure that the gloves you plan on using are compatible with Chromerge.

Refer to glove selection chart from the links below:

Eye Protection:

ANSI approved properly fitting safety glasses or goggles are required. A face shield may also be appropriate depending on the specific application.



Skin and Body Protection:

Lab coat, full-length pants, and closed-toe shoes are required.



Hygiene Measures:

Avoid contact with skin, eyes, and clothing. Wash hands before and immediately after handling the product.



Section 6 – Engineering Controls

Use of Chromerge should be conducted in a properly functioning chemical fume hood whenever possible. The chemical fume hood must be approved and certified by EH&S and have a face velocity between 85 – 125 feet per minute. Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower.



Section 7 – First Aid Procedures

If inhaled:

Move into the fresh air and get medical aid immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.



In case of skin contact:

Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash any contaminated clothing before reuse. Thoroughly clean shoes before reuse. Consult a physician.



In case of eye contact:

Check for and remove any contact lenses. Rinse thoroughly with plenty of water for at least 15 minutes. Assure adequate flushing by separating the eyelids with fingers. Seek immediate medical attention.



If swallowed:

Seek immediate medical attention. Do NOT induce vomiting. If conscious and alert, rinse out mouth with water. Never give anything by mouth to an unconscious person.



Section 8 – Special Handling and Storage Requirements

  • Avoid contact with skin, eyes, and clothing. Do not breathe vapor.

  • Keep container tightly closed in a dry and well-ventilated area. If possible, store in corrosive/acid/lab storage cabinet within a secondary containment (nalgene/ polypropylene tray or tub). Store in original container away from direct sunlight.

  • Avoid contact with strong bases, sulfur, sodium, phosphorus, alcohols, aluminum, alkali metals, ammonia, reducing agents, and all organic materials including organic solvents.

  • Keep away from combustible materials, heat, sparks, and open flame.

  • Do not store in the top most shelf of the storage cabinet. In general, do not store chemicals at or above eye level.

  • Ensure the container is tightly closed at all times.

Section 9 – Spill and Accident Procedures

Chemical Spill Dial 8-1911

Immediately evacuate area and ensure others are aware of the spill. If there is an imminent threat of a fire, pull the nearest fire alarm station to evacuate the building and dial 8-1911. If the spill is minor and does not pose a threat to personnel, contact EH&S at 8-8411 during normal business hours (7:30 AM – 4:30 PM) for spill cleanup assistance (dial 8-1911 if spill occurs after hours and assistance is needed).



Chemical Spill on Body or Clothes:

Remove clothing and begin first aid procedures (Section 7) immediately.  Seek medical attention; dial 8-1911.



Chemical Splash into Eyes:

Immediately rinse eyes and begin first aid procedures (Section 7) immediately.  Seek medical attention; dial 8-1911.



Section 10 – Medical Emergency

Life Threatening Emergency, After Hours, Weekends And Holidays:

Dial 911.

Non-Life Threatening Emergency:

Immediately report injury to supervisor and complete the First Report of Injury. http://www.marquette.edu/riskunit/riskmanagement/documents/Employee_First_Report_of_Incident.pdf



Section 11 – Waste Disposal Procedures

Label Waste:

Make sure the waste container(s) is properly labeled; label should indicate all of the contents of the container. EH&S provides hazardous waste labels free of charge, contact dennis.daye@marquette.edu to obtain labels.



Store Waste:

Store hazardous waste in closed containers, and in a designated area. Chromerge waste should be segregated from all incompatible chemicals such as caustics.



Dispose of Waste:

Complete a Chemical Waste Pickup Request Form to arrange for disposal by EH&S. Contact dennis.daye@marquette.edu or visit the EH&S webpage for questions. http://www.marquette.edu/riskunit/environmental/documents/waste_disposal_form.pdf



Section 12 – Safety Data Sheet (SDS)

A current copy of the Chromerge SDS must be made available to all personnel working in the laboratory at all times. To obtain a copy of the SDS, refer to Marquette’s MSDS library http://www.marquette.edu/riskunit/environmental/documents/msds_library.pdf or contact the chemical manufacturer. Many manufacturers’ SDSs can be found online on websites such as Sigma-Aldrich (http://www.sigmaaldrich.com/united-states.html) or Siri MSDS Index (http://hazard.com/msds/).
