NONE
ACGIH Biological Exposure Indices(BEI): 50 micrograms
(lead) per liter in blood; 150 micrograms (lead) per gram

CADMIUM: Cadmium (Cd CAS 7440-43-9) is a constituent in batteries
which have been used in lighthouses such as: Nickel-Cadmium
HED and ED Series, Exide EI and FHGS Series, and GNB Absolyte-
II Series. Since these batteries were used at lighthouses, the
likelihood of release of these batteries into the aquatic
environment around aides to navigation is minimal.
GENERAL DESCRIPTION:
Cadmium is a silver- white, malleable
metal.
HEALTH HAZARDS: Cadmium is a confirmed human lung carcinogen.
Inhalation is the primary route of exposure. Acute exposure to
cadmium dust may result in pulmonary irritation. Repeated
exposure to lower levels of airborne cadmium may result in
chronic poisoning characterized by irreversible lung injury.
Short term symptoms of airborne cadmium exposure include
anemia, eosinophiliea, yellow discoloration of the teeth, and
rhinitis.
EXPOSURE LIMITS:
ACGIH TLV:
0.05 mg/M3.
ACGIH Biological Exposure Indices(BEI): 10 micrograms per
liter in
blood: 10 micrograms (lead) per gram
creatine in urine
OSHA PEL:
0.2 mg/M3.(as dust)
OSHA CEILING:
0.6 mg/M3.
NIOSH REL:
0.10 mg/M3.
IDLH:
NONE
METHYL MERCURY: Methyl mercury (CH3Hg; CAS: 22967-92-6) may
be present at primary battery
