  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Liquid formulations containing organic solvents may be flammable.    NO open flames.    Use water spray, powder, foam, carbon dioxide.   

 PREVENT DISPERSION OF DUST! STRICT HYGIENE!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat. Dizziness. Headache. Weakness. Muscle pain. Incoordination. Fever.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety spectacles or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Nausea. Vomiting. Abdominal pain. Diarrhoea. Further see Inhalation.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. 

According to UN GHS Criteria

 

Transportation
UN Classification

CHLOROBENZILATE ICSC: 0749
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS OR PALE YELLOW CRYSTALS. 

Physical dangers
No data. 

Chemical dangers
Decomposes on heating. This produces toxic and corrosive fumes. Reacts with strong acids, bases and strong oxidants. This generates fire hazard.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation and by ingestion. 

Effects of short-term exposure
The substance is irritating to the eyes and skin. The substance may cause effects on the central nervous system. This may result in impaired functions. 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. 

Effects of long-term or repeated exposure
 


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal. 

NOTES
The substance is combustible but no flash point is available in literature.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
