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 Risk of fire and explosion if formulations contain flammable/explosive solvents.


EXPOSURE
PREVENT DISPERSION OF DUST!

 •INHALATION Cough. Sore throat. Headache. Nausea.
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. Refer for medical attention.
 •EYES Redness. Pain. Burns. Blurred vision.
Safety goggles or eye protection in combination with breathing protection if powder.
Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.
 •INGESTION Burning sensation in the throat and chest. Abdominal pain. Nausea. Diarrhoea. Unconsciousness. Vomiting. Weakness. Shock or collapse.
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Give one or two glasses of water to drink. Refer immediately for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place.
Provision to contain effluent from fire extinguishing. Separated from strong bases, food and feedstuffs . Store in an area without drain or sewer access. Cool. acid)
Do not transport with food and feedstuffs.

PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALLINE POWDER , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating producing toxic and corrosive fumes including hydrogen chloride and phosgene . The substance is a weak acid. Attacks many metals in the presence of water.

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:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the skin and the respiratory tract. The substance is corrosive to the eyes. The substance may cause effects on the nervous system and heart, when ingested in large amounts.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
PHYSICAL
PROPERTIES
Melting point: 113-119°C
Relative density (water = 1): 1.3
Solubility in water:
none
Vapour pressure, Pa at 20°C: negligible
Octanol/water partition coefficient as log Pow: 2.8
ENVIRONMENTAL
DATA
Environmental Hazard placard The substance is very toxic to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal. edient in herbisides
N O T E S
MCPA is a chlorophenoxy-herbicide which, as a group, has been classified as possibly carcinogenic to humans. Depending on the degree of exposure, periodic medical examination is suggested. Carrier solvents used in commercial formulations may change physical and toxicological properties.
