PURPOSE:
To ensure that employee’s exposure to PCBs is minimized
and that material containing PCBs are handled and disposed of in
an environmentally sound manner.
BACKGROUND:
Polychlorinated bi-phenyls (PCBs) were used in the capacitors
of fluorescent lamp ballasts and in the capacitors of high intensity,
discharge (HID) lighting fixtures. PCBs were also found in other
electrical equipment including common household appliances. PCBs
were used in these items as they were an excellent insulator and
they would not burn.
In 1978 however, the United States Environmental Protection Agency
(EPA) banned the use of PCBs as they were found to pose a health
risk to humans. Mineral oils and powdered materials replaced PCBs
in lamp and ballast and capacitors manufactured after 1978 and
these items generally bear a label reading “No PCBs”.
The majority of ballasts and capacitors you will come into contact
with in your day to day job activities pose no health risk. However,
you may be working on ballasts and/or capacitors that contain very
small amounts of PCB fluid. For handling these ballasts and capacitors,
follow the handling and disposal procedures outlined below.
HANDLING PROCEDURES:
Procedure for removal of ‘non leaking’ PCB capacitors
from fluorescent lamp ballasts. Employee will wear the following
safety equipment:
1. Gloves made of chemical resistant neoprene coated, butyl rubber,
or leather.
2. Safety glasses with side shields or full face shield.
3. Safety toed shoes or boots.
STEP 1:
Once removed from the fixture, the Toxic Substance Control Act
(TSCA) requires that PCB ballasts be stored in approved DOT drums.
The drums should be stored inside the building. Outside storage
is permitted if they are on an impervious surface, the drum lids
are secured, and they are protected against weather and vandalism.
STEP 2:
Separate ballast by type (PCB, non-PCB) and visually check for
leakers, and place into drums.
NOTE: Leaking PCB ballasts must be double bagged and placed in
a drum containing at least 3 inches of vermiculite.
STEP 3:
Properly label drums PCB or Non PCB. Secure drum lid.
All protective equipment that comes into contact with any material
leaking from a capacitor will be placed in proper containers
for disposal. The employee shall wash his/her hands with soap
and water when beginning a work shift, before a break, and upon
completion of the work shift. No tobacco materials, food, or
beverages will be permitted while working with lamp ballasts.
It is the employee’s responsibility to ensure that these
handling and disposal procedures are fully carried out. The proper
use of the prescribed safety equipment will protect the employee
from the potential dangers of contamination from PCBs. |
