TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   STRICT HYGIENE!   
Inhalation Burning sensation. Cough. Nausea.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Headache. Nausea. Vomiting. Weakness. Unconsciousness.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention .

IMPORTANT DATA
Physical State; Appearance
COLOURLESS-TO-BROWN CRYSTALLINE POWDER. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic fumes including hydrogen chloride. The solution in water is a weak acid. Attacks some forms of coatings and metals in the presence of moisture. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK (not established):. 

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly on spraying or when dispersed, especially if powdered. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. 

Effects of long-term or repeated exposure
See Notes. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 94°C
Density: 1.28 g/cm³
Solubility in water, g/100ml at 25°C: 0.07
Vapour pressure, Pa at 22.5°C: 0.08

The substance is harmful to aquatic organisms. 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
Mecoprop is a chlorophenoxy-herbicide which, as a group, has been classified by IARC (1987) as possibly carcinogenic to humans, but the data on this specific substance are inconclusive.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
Other CAS number 7085-19-0.
