PURPOSE:

Provide guidance to NCSU staff on actions to be taken when a hazardous material spill occurs. For this section, the term "spill" includes gas releases as well as solid and liquid spills.

SPILL / LEAK PREPAREDNESS / PREVENTION

Obtain chemicals in smallest bottles possible to meet needs. Keep fume hoods clean, free of containers no longer in use. Store large quantities (gallon containers) of flammable liquids in compartments in flammable liquid storage cabinets or, if limited quantity, in the base cabinet under your hood. Avoid use of mercury thermometers. If mercury containing instruments must be used, provide secondary containment in the event of breakage or spills. For large scale chemical baths in equipment, provide secondary containment,if possible. Secondary containment is required for containers of liquid waste stored outside of your hood. Assure hazardous gases are stored in exhausted gas cabinets and are equipped with flow restricting orifices according to University guidelines (see Compressed Gas Safety requirements). Labs with hazardous gases should contain emergency power off buttons which will shut down gas valves INSIDE the exhausted cabinet in the event of emergency. Where highly toxic or pyrophoric gases are used, monitors which will alarm and cause gas valves to shut are required.

TRAINING

Hazard communication training is required for all persons prior to use of hazardous materials. Personnel are required to be familiar with the hazard properties of the materials they use and the steps to be taken in the event of emergencies. Adequate detail in the lab safety plan on this subject and review of the plan content by all employees is required.

MATERIALS

Material safety data sheets must be on hand in the laboratory or work area for ALL TRADE NAME MATERIALS. These are chemical mixtures which are often not available through on-line material safety data sheet databases. These MSDSs (SDS) should be stored in a safe area so they are readily available for use and reference in an emergency (suggest you keep them by your safety plan in your lab or work area. Spill control materials should be kept on hand for spill response, along with the necessary protective equipment to be used. Minimum supplies for the following materials listed below, available at Central Stores, should be kept in each lab or chemical work area.

Protective Clothing Spill Control Materials

Chemical Splash Goggles (2)
Full face shields (2)
Neoprene Gloves (long) (2)
Rubber aprons (2)
Rubber shoe covers (2)

One bag / box absorbant
5 gal pails (2)
Polypropylene dust pans (2)
Half gallon ziplock bags (4)
Waste disposal labels

NOTE: Persons who are, for any reason, uncomfortable cleaning up spills within the guidelines listed below should contact their supervisors or principle investigators ASAP (don't wait until spill occurs) so that alternate department spill response plans, if appropriate, can be made.

NOTE: THE TRAINING AND EQUIPMENT LISTED ABOVE WILL NOT NECESSARILY EQUIP PERSONNEL TO HANDLE ALL SPILLS. CLICK HERE FOR MORE DETAIL
