corrosive materials (e.g. assume all strong alkylating agents are corrosive). Specific substances [Add details of specific substances you will be using in the lab under this SOP.] Designated work areas/signage For low hazard work with corrosives (limited quantities, low concentrations, or weak corrosives), the lab may be considered the designated area provided the lab door signs include appropriate warning pictograms. More hazardous work with corrosives should be done at designated areas within the lab where spillage can be easily contained (e.g. a fume hood) and which should be signed “Warning — Corrosive” (or equivalent wording). If highly hazardous work is being performed, additional signage giving the name of the responsible individual and contact number is also recommended. Corrosive work and storage shall be serviced by a regulatory-compliant safety shower/eyewash combination. Corrosive materials shall NOT be handled or stored if this requirement is not met. Additionally, an eyewash shall be immediately adjacent to the hazard if a acid or strong caustic” is used “strong (ANSI Z385.1). Please refer to the CHP for more information on safety shower/eyewash requirements. Email if further information is required. [Add lab-specific work area and signage information here, if needed.] Unattended experiments Unattended hazardous experiments should be signed according to the requirements of the . Storage Requirements Corrosive materials should be stored in cool, dry well-ventilated areas below eye level, away from sunlight in an upright and tightly closed manner. Concentrated acids and bases should be stored in dedicated cabinets in appropriate secondary containment (e.g. polypropylene trays). Separate cabinets should be used to segregate acids from bases, segregate organic from inorganic acids, segregate oxidizing acids from reducing/flammable/combustible acids, and segregate organic from inorganic bases. If there is lack of space, separate secondary containment within the same cabinet may separate incompatible materials provided excessive hazard is not thereby created; EH&S can advise on a case-by-case basis. Avoid storing volatile acidic corrosives (e.g. hydrochloric acid) in metal cabinets as this may lead to corrosion. If this must be done, placing a container of activated carbon or calcium hydroxide in the cabinet will absorb vapor and reduce corrosion.
