'''Laboratory Director (LD) Approval is Required Prior to Performing this Procedure
'''
==Description==
This standard operating procedure (SOP) outlines the handling and use of corrosive chemicals. In accordance with this document, laboratories should use appropriate controls, personal protective equipment, and disposal techniques when handling corrosive chemicals.
A corrosive chemical is defined by meeting one the following:
*Corrosive chemicals will damage substances that they make contact with and they are immediately dangerous to living tissue.
*Most corrosive chemicals are acids and bases however; other chemicals can be corrosive as well. Always check chemical product information.
*Some common corrosive acids include hydrochloric acid, sulfuric acid, and nitric acid. Examples of corrosive bases are ammonium hydroxide, potassium hydroxide, and sodium hydroxide.
If you have questions concerning the applicability of any item listed in this procedure contact the LD/Laboratory Supervisor or Occupational Safety and Environmental Health at (734) 647-1143.
==Process==
Refer to the steps in the protocol and the Safety Data Sheet (SDS) for using the corrosive chemical in question for information regarding the steps needed to securely handle that particular corrosive chemical.
==Potential Hazards==
Corrosive chemicals can cause destruction of living tissue by chemical action at the site of contact and can be solids, liquids, or gases. Corrosive effects not only can occur on the skin and eyes, but also in the respiratory tract and, in the case of ingestion, in the gastrointestinal tract as well. While acids and bases are familiar corrosives, many other materials are corrosive to the body as well (including [[SOP - Bleach]] and [[SOP- Phenol]]).
Review the Safety Data Sheet (SDS) of the material to determine if it is corrosive and to identify other hazards. If the material also has other physical hazards or health hazards, follow those appropriate SOP as well.
Refer to SOP templates for hydrofluoric [http://ehs.umich.edu/wp-content/uploads/sites/37/2016/02/HydrofluoricAcid.docx|hydrofluoric acid], perchloric [http://ehs.umich.edu/wp-content/uploads/sites/37/2016/02/PerchloricAcid.docx|perchloric acid], [[SOP- Phenol]], and [[SOP - Bleach]].
Acutely toxic and reactive acids meeting the MIOSHA definition of a Particularly Hazardous Substance (see below) require customized SOPs with laboratory director approval that incorporate their toxic and/or reactive hazards.
'''Notes'''
The University of [http://ehs.umich.edu/wp-content/uploads/sites/37/2016/03/ChemicalHygienePlan.pdf|Michigan’s Chemical Hygiene Plan] requires specific measures to take in order to ensure laboratory employee protection, including provisions for additional employee protection for work with Particularly Hazardous Substances. These include "select carcinogens," reproductive toxins and substances which have a [http://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=INTERPRETATIONS&p_id=20048|high degree of acute toxicity], e.g., hydrogen cyanide, hydrogen sulfide, and nitrogen dioxide.
Specific consideration shall be given to the following provisions which shall be included where appropriate for each '''Particularly Hazardous Substance''':
* Establishment of a designated area;
* Use of containment devices such as fume hoods or glove boxes;
* Procedures for safe removal of contaminated waste; and
* Decontamination procedures.
Environment, Health & Safety (EHS) can assist researchers by providing additional information on working with Particularly Hazardous Substances. General guidelines and recommendations for the safe handling, use and control of hazardous chemicals and particularly hazardous substances can be found in a chemical’s SDS [http://ehs.umich.edu/research-clinical/chemical/safety-data-sheets/|SDS] and in other [http://ehs.umich.edu/research-clinical/chemical/safety-data-sheets/|chemical hazard references].
==Engineering Controls==
*Where the eyes or body of any person may be exposed to corrosive chemicals, suitable facilities for quick drenching or flushing of the eyes and body shall be provided within the work area for immediate emergency use. Bottle type eyewash stations are not acceptable.
*A safety or drench shower should be available in a nearby location where the corrosive material is used.
*Depending on the material’s pH or based on its ability to cause severe tissue damage, e.g., formaldehyde, methylene chloride, methyl ethyl ketone peroxide (MEKP), phenol, etc., the location of the emergency shower and/or emergency eyewash shall be within 25 to 100 feet from the hazardous operation.
*Manipulation of some corrosive materials outside of a fume hood may require special ventilation controls in order to minimize exposure to the material. Fume hoods provide the best protection against exposure to corrosive materials in the laboratory and are the preferred ventilation control device.
==Work Practice Controls==
*Segregate the various types of corrosives. Separate acids and bases. Liquids and solids should also be separated. Specially designed corrosion resistant cabinets should be used for the storage of large quantities of corrosive materials. Store corrosives on plastic trays. Do not store corrosive materials on high cabinets or shelves.
*Nitric acid should be stored in secondary containment in a well-ventilated area that is separated from organics and other combustible materials and incompatibles. Also refer to the SOP for hydrofluoric acid, nitric acid, picric acid and sulfuric acid.
*'''Containers''': All corrosive chemicals must be clearly labeled with the correct chemical name. Handwritten labels are acceptable; chemical formulas and structural formulas are not acceptable.
'''Notes'''
Employers may choose to label secondary, portable or in-house workplace containers with label alternatives that meet the requirements for the new Hazard Communication Standard (HCS). Alternative labeling systems such as the National Fire Protection Association (NFPA) the Hazardous Material Information System (HMIS) are permitted for workplace containers. However, the information supplied on these labels must be consistent with the revised HCS, e.g., no hazard warnings or pictograms that conflict with GHS.
==Personal Protective Equipment==
In order to select the appropriate PPE for the workplace, a hazard assessment is conducted. The hazard assessment determines the hazards and potential hazards associated with a task, machinery, or process. The appropriate PPE for the situation may be subsequently determined.
The Hazard Assessment Form may be found here. It may be completed either by the workplace supervisor or the department’s EHS representative.
Eye protection in the form of safety glasses must be worn at all times when handling corrosive materials. Ordinary (street) prescription glasses do not provide adequate protection. (Contrary to popular opinion these glasses cannot pass the rigorous test for industrial safety glasses.) Adequate safety glasses must meet the requirements of the ''American National Standard for Occupational and Educational Personal Eye and Face Protection Devices'' (ANSI/ISEA Z87.1) and must be equipped with side shields (that also meet the requirements of ANSI/ISEA Z87.1). Safety glasses with side shields do not provide adequate protection from splashes; therefore, when the potential for splash hazard exists other eye protection and/or face protection must be worn. It is recommended that face shields be worn when a splash potential exists with corrosive materials.
Gloves must be worn when handling corrosive chemicals. Disposable nitrile gloves provide adequate protection against accidental hand contact with small quantities of most laboratory chemicals. Below are some glove material recommendations for some common acids.

'''Note''' The recommendations above are based on typical laboratory concentrations and uses. Refer to the acid’s SDS as well as Glove Compatibility Charts for each particular concentration of acid for additional recommendations, especially for unusual concentrations or use of a particular acid.
Lab workers should contact EHS for advice on chemical resistant glove selection when direct or prolonged contact with hazardous chemicals is anticipated. The EHS [http://ehs.umich.edu/research-clinical/planning-safe-research/glove-compatibility-chart/|Glove Compatibility] webpage can also be used to determine the recommended gloves.
Lab coats, long pants, closed toed shoes and long sleeved clothing should be worn when handling corrosive materials. Additional protective clothing should be worn if the possibility of skin contact is likely.
Safety shielding is required any time there is a risk of explosion, splash hazard or a highly exothermic reaction. All manipulations of corrosive materials which pose this risk should occur in a fume hood with the sash in the lowest feasible position. Portable shields, which provide protection to all laboratory occupants, are acceptable.
==Transportation and Storage==
*Transport corrosives in secondary containment, preferably a polyethylene or other non-reactive acid/solvent bottle carrier.
*Store in well-ventilated areas with secondary containment, such as a non-reactive plastic bin.
*Store below eye level.
*Store away from metal (unless the metal has a corrosion-proof coating), and do not store under the sink.
*Store away from incompatibles – many corrosive materials are incompatible with each other – oxidizing acids are incompatible with organic acids, and acids are incompatible with bases. *Review the chemical’s Safety Data Sheet (SDS) for additional incompatibility information.
Avoid storing on the floor. If storing on the floor is necessary, use secondary containment.
==Waste Disposal==
Most spent, unused and expired corrosive materials are considered hazardous wastes and must be collected and disposed of within 90-days by EHS’s Hazardous Materials Management (HMM) Group. Contact EHS-HMM at (734) 763-4568 for waste containers, labels, manifests, waste collection and for any questions regarding proper waste disposal.
