1-4-Dichlorobeneze (Enoz)

Mothballs are small balls of chemical pesticide and deodorant, sometimes used when storing clothing and other articles susceptible to damage from mold or moth larvae (especially clothes moths like Tineola bisselliella). Use of mothballs when clothing is stored out-of-season has given rise to the colloquial usage of the terms "mothballed" and "put into mothballs", to refer to anything which is put into storage or whose operation is suspended.

SECTION 3:  HAZARDS IDENTIFICATION 
 
Emergency Overview:  White balls, blocks, crystals, nuggets or tablets. Some products may be incased 
in paper bags (packets) or plastic containers and some products contain 
fragrance. Harmful if swallowed or inhaled. Dust and vapors may cause eye and 
respiratory tract irritation. Flammable.

Relevant Routes of Exposure:  Inhalation, Ingestion, Eye Contact, Skin Contact. 
 
Acute Effects:   
Ingestion:   Symptoms may also include nausea, vomiting, diarrhea, and stomach distress. 
Eyes:  Vapors may cause irritation. Dust or particles can cause severe irritation. 
Inhalation:  Dust and vapors can cause respiratory tract irritation.  Vapor concentrations of p-
dichlorobenzene that exceed permissible exposure limits can cause central nervous system 
depression. Symptoms could include the dizziness, blurred vision, nausea, feeling of drunkenness, 
unconsciousness and even death. 
Skin:  Repeated or prolonged contact may cause a skin irritation.

Target Organs:  Ocular, respiratory, dermal, liver, kidneys, central nervous (CNS). 
 
Medical Conditions Aggravated By Exposure: Liver, kidney, chronic respiratory disease. 
 
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.  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.  
 
 
 
Page 3 of 9 
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 8:  EXPOSURE CONTROLS/PERSONAL PROTECTION 
 
General Hygienic Practices: 
Do not get on eyes, skin, or clothing. 
Do not breathe vapors, dust or fumes. 
Wash thoroughly after handling. 
 
Recommended Exposure Limits:   
 
p-dichlorobenzene: ACGIH TLV: 10 ppm (60 mg/m3)   8-hr TWA  A3* 
*ACGIH has designated this component as an "A3" substance thereby                               
including it among substances that are animal carcinogens with                                          
unknown relevance to man.
