#1 PROCESS

Mixing various concentrations of aqueous acid solutions.

#2 HAZARDOUS CHEMICALS/CLASS OF HAZARDOUS CHEMICALS

Acids - nitric, sulfuric, hydrochloric, acetic, phosphoric

#3 PERSONAL PROTECTIVE EQUIPMENT

Safety goggles, nitrile, PVC, or neoprene gloves. Avoid skin contact, serious burns may result. Gloves made of nitrile, neoprene, or PVC can provide effective skin protection. Wear safety glasses or chemical safety goggles with face shield when using large quantities, or chemical safety goggles when using small quantities. Wear rubber, neoprene, or PVC apron when using large quantities and splash potential exists.

#4 ENGINEERING/VENTILATION CONTROLS

Use concentrated acids in fume hood. A safety shower and eyewash must be available and accessible when working with corrosive liquids.

#5 SPECIAL HANDLING PROCEDURES AND STORAGE REQUIREMENTS

Store mineral acids together, separate from oxidizing agents and organic materials. Store containers of acids and bases separately in chemical resistant secondary containers. This could be a polyethylene,  PYREX or Nalgene tray or pan.

ACID & CORROSIVE CABINETS 

Bottles of acid should be stored in an acid (corrosive) cabinet. While
acids and bases are both considered to be corrosive, care must be taken to not
store acids and bases in the same cabinet. It is particularly important to
avoid storing ammonium hydroxide and strong mineral acids in the same cabinet.

Oxidizing acids, such as fuming nitric, fuming sulfuric and nitric should
be stored separately, in a secondary container within an acid cabinet.
Polypropylene boxes for use in acid cabinets are available commercially.

Glacial acetic acid, although it is both a corrosive and flammable, should be
stored with other, non-oxidizing acids away from those mentioned above, not in a flammables cabinet.
 

#6 SPILL AND ACCIDENT PROCEDURES

Skin exposure: Rinse affected skin with plenty of water while removing contaminated clothing and shoes. Rinse for at least 15 minutes. Seek medical attention.

Eye exposure: Splashes may cause tissue destruction. Wash eyes for at least 15 minutes, lifting the upper and lower eyelids occasionally. Seek medical attention immediately.

Small spills: Do not attempt cleanup if you feel unsure of your ability to do so or if you perceive the risk to be greater than normal laboratory operations. Cover spill with sodium carbonate or bicarbonate. When reaction stops pickup with damp sponge or paper towels.

Large Spills: Notify others in area of spill. Turn off ignition sources in area. Evacuate area and post doors to spill area. Call EH&S: 
 
* Office of Environmental Health & Safety 292-1284 
* University Police 911  This is a 24 hour service. 

 Remain on the scene, but at a safe distance, to receive and direct safety personnel when they arrive.  Restrict persons from area of spill or leak until cleanup is complete. Remain in area in safe location to assist EH&S with response.

#7 WASTE DISPOSAL

Dispose of waste through EH&S.

#8 SPECIAL APPROVAL REQUIRED

NO

#9 DECONTAMINATION

Use sodium bicarbonate and water.

#10 DESIGNATED AREA

NO
