Skin: Repeated or prolonged contact could cause skin irritation. Naphthalene can be absorbed
through the skin and may cause systemic toxicity. Dermal contact may cause hypersensitive
dermatitis.
Carcinogenicity: IARC – There is inadequate evidence in humans for the carcinogenicity of naphthalene
but sufficient evidence in experimental animals for carcinogenicity: Group 2B, possibly carcinogenic to
humans. EPA’s Integrated Risk Information System (IRIS) – Available data are inadequate to establish a
causal association between exposure to naphthalene and cancer in humans.
Reproductive Effects: None known.
Target Organs: Ocular, respiratory, dermal, central nervous system, hemopoietic, and gastrointestinal.
Medical Conditions Aggravated By Exposure: None known.
SECTION 4: FIRST AID PROCEDURES
First Aid Procedures:
EYES: Immediately flush eyes with a directed stream of water for at least 15 minutes, forcibly holding
eyelids apart to ensure complete irrigation of all eye and lid tissue. Remove contact lenses, if
present, after the first five minutes and continue rinsing the eye. If irritation persists, call a
physician or poison control center immediately.
SKIN: Immediately flush skin with plenty of water while removing contaminated clothing and shoes.
Wash clothing before reuse. If irritation occurs, get medical attention.
INHALATION: Move person to fresh air. If person is not breathing, call 911 or an ambulance, then give
artificial respiration preferably mouth-to-mouth if possible. Call a poison control center or doctor
for further treatment advice.
INGESTION: Do not give anything by mouth to an unconscious person. Call poison control center or
doctor immediately for treatment advice. Have person rinse the mouth with water. If able to
swallow, have the person sip a glass of water. Do not induce vomiting unless told to do so by a
poison control center or doctor.
SECTION 5: FIRE HAZARDS
Unusual Fire and Explosion Hazards: Combustible in presence of open flame and sparks. Material in
powder form is capable of creating dust explosion. Yields flammable vapors on heating above the melting
point. Forms explosive mixture with air.
Fire Fighting Procedures:
NIOSH approved positive pressure, self-contained breathing apparatus and full protective turn-
out gear.
Evacuate personnel to an area upwind to avoid smoke and vapors.
Remove containers of this material if it can be done safely.
Use water to keep fire exposed containers cool.
Protective clothing and equipment must be decontaminated if contact with the material or vapors
has occurred.
Extinguishing Media: All common extinguishing media are suitable.
