Laser Classes
  • CLASS 1
  • Safe under all conditions of normal use

    viewed through optical instruments
  • Class 3R
  • Safe if handled carefully with restricted beam
    viewing

15
Laser Classes (continued)
  • Class 3B
  • Hazardous if the eye is exposed directly, but

UCR Pesticide Pits Project
88
Minimize Waste Generated
  • When practical, reduce hazard characteristics of
    by-products before they become waste
  • Reduce the potential for exposure
  • Green Chemistry www.epa.gov/greenchemistry

89
Minimize Waste Generated
  • Neutralize
  • If pH is the only hazard, and the pH of the waste
    is between 2 and 12.5, then
  • The waste can be neutralized in batches of 5
    gallons or less to a pH of 5 to 9 and may be able
    to drain dispose
  • Documentation training is required
  • Substitute non-hazardous chemicals
  • Includes buffer solutions
  • Work on a small scale whenever possible
  • Use less reagents create less waste

90
Illegal Actions
  • Evaporate waste (atmospheric disposal)
  • Drain disposal of untreated chemically hazardous
    waste
  • Strictly regulated, generally prohibited
  • No treatment in the pipes
  • Only untreated chemicals allowed
  • Bleach (store grade)
  • Non-hazardous salt solutions

91
Store in Appropriate Area(Large Quantity
Generator)
  • Satellite accumulation areas
  • An area in the lab designated for the proper
    storage of chemical hazardous waste
  • Store only small quantities
  • 1 quart max of acutely hazardous waste
  • Picked-up at 80 full or after 6 months

92
Satellite Accumulation Areas
  • Under the control of the operator of the process
    generating the waste
  • Inspected weekly by the lab
  • Waste prepared appropriately and incompatible
    materials segregated

93
Extremely Hazardous Waste
  • Triple rinse containers
  • Collect rinseate as waste
  • Deface the label

94
Pesticide Waste
  • Regulated
  • Triple rinse containers
  • Make containers unusable
  • Use rinseate to dilute next batch when possible

95
Preparing Labeling Universal Waste
  • Label as universal waste or used batteries,
    or used lamps etc.
  • Not dead batteries
  • Mark with the date that accumulation began
  • Request pickup lt 9 months
  • Contain to prevent damage or leakage

96
Preparing Unknown Waste
  • Avoid creating them in the first place!
  • Provide as much information as you can
  • Process that generated the waste
  • Best guess on identification
  • HAZCAT analysis

97
Preparing Biohazard/Medical Waste
  • Storage requirements for red bagged waste and
    filled sharps containers
  • Over zero C - not more than 7 days
  • Under zero C not more than 90 days
  • If autoclaving medical waste must use registered
    autoclaves
  • Bag must be weighted and recorded
  • Use autoclave indicator tape
  • Contact Biosafety with questions
  • Use Red Bags ONLY for biohazard waste, not as
    general trash bags

98
Segregating Waste
  • Physical states
  • Incompatible hazards
  • Oxidizers from organics
  • Acids from bases
  • See poster for complete list
  • Minimize mixtures
  • A solution that contains more than one hazard
    class DOES NOT need to be separated
  • Components of the mixture need to be tracked

99
Waste Preparation Containers
  • Container must be compatible with contents
  • No food containers!
  • Containers closed when not in use
  • when not actively being filled
  • Free from external contamination
  • In good condition
  • No evidence of cracks, dents, corrosion
  • Labeled with Hazardous Waste Label

100
Secondary Containment
  • Waste container must be placed in secondary
    containment
  • Holds 110 of the volume of the largest container

101
Waste Disposal When?
  • Container should be 80 full
  • Reduces the number of containers shipped
  • Reduces amount of time on pickups
  • Minimizes costs to the university

102

    materials and proper training to clean it up?
