TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Highly flammable.  NO open flames, NO sparks and NO smoking.  Use powder, AFFF, foam, carbon dioxide. 
EXPLOSION Vapour/air mixtures are explosive.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   AVOID EXPOSURE OF (PREGNANT) WOMEN! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Confusion. Dizziness. Drowsiness. Headache. Nausea. Unconciousness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer for medical attention. 
Skin Dry skin.  Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Further see Inhalation.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Ventilation. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer.   
EC Classification
 
UN Classification
UN Hazard Class: 3 
GHS Classification
 

EMERGENCY RESPONSE SAFE STORAGE
  Fireproof. Separated from strong acids and oxidants. Well closed. 

IMPORTANT DATA
Physical State; Appearance
COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
The vapour mixes well with air, explosive mixtures are easily formed. As a result of flow, agitation, etc., electrostatic charges can be generated. 

Chemical dangers
Reacts violently with oxidants and strong acids such as nitric and sulfuric acids. This generates fire and explosion hazard. Attacks plastics and rubber. 

Occupational exposure limits
 

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

Inhalation risk
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. 

Effects of short-term exposure
The substance is irritating to the eyes. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. The substance may cause effects on the central nervous system. Exposure could cause lowering of consciousness. Exposure could cause cardiac arrythmia. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the nervous system, liver and kidneys. May cause reproductive toxicity in humans. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA

Solubility in water: none
Flash point: 4.5°C
Auto-ignition temperature: >300°C
Explosive limits, vol% in air: see Notes 
The substance is toxic to aquatic organisms. 

NOTES
CAS number for 641 Thinner is 64742-89-8.
The physical properties are dependent on the formulations of the product.
Use of alcoholic beverages enhances the harmful effect.
Depending on the degree of exposure, periodic medical examination is indicated.
Petroleum 50 thinner is a mixture of paraffins, monocycloparaffins, condensed cycloparaffins, benzene, toluene and alkyl benzenes.
In the EC the product may be labeled with F, Xn; R: 11-20; S: 9-16-29-33.
Also consult ICSC 0078 Toluene.
