ASPIRATION HAZARD IF SWALLOWED - CAN ENTER LUNGS AND CAUSE DAMAGE 

MAY CAUSE DAMAGE TO THE FOLLOWING ORGANS: LUNGS, NERVOUS SYSTEM, 

DIGESTIVE SYSTEM, RESPIRATORY TRACT, SKIN, EYES. 

Routes of Entry 

Absorbed through skin. Dermal contact. Eye contact. Inhalation. Ingestion. 

Potential Acute Health Effects 

Eyes May cause eye irritation. 

Skin May cause skin irritation. Skin inflammation is characterized by itching, scaling, reddening, or, 

occasionally, blistering. 

Inhalation High vapor/mist concentration exposure can cause respiratory tract irritation, nausea, 

headaches, dizziness, and other central nervous system effects. 

Ingestion May cause irritation of gastrointestinal tract. If swallowed, aspiration into lungs may result in 

chemical pneumonitis and severe pulmonary injury. 

Potential Chronic Health 

Effects 

Chronic overexposure to this material may cause systemic toxicity, including adverse 

reactions to the following: kidney, liver, spleen, adrenals, lungs, skin, blood, testes, 

cardiovascular and nervous systems. 

CARCINOGENIC EFFECTS: 

Ethylbenzene: 

Classified A3 (Proven for animals.) by ACGIH 

2B (Possible for humans.) by IARC 

Classified None. by OSHA. 

Mixture may contain other minor (less than 0.1 %) components that may be known to cause 

cancer. 

TERATOGENIC EFFECTS: Mixture may contain minor (less than 0.1 %) components that 

may cause adverse reproductive and/or developmental effects. 

Medical Conditions 

Aggravated by 

Overexposure 

Pre-existing disorders involving any target organs mentioned in this MSDS as being at risk 

may be aggravated by over-exposure to this product.

Overexposure /Signs/ 

Symptoms 

See Toxicological Information (Section 11) 

_ 

Prolonged or repeated exposure to this product can cause central nervous system effects 

(headache, excitation, euphoria, dizziness, incoordination, drowsiness, light-headedness, 

blurred vision, fatigue, tremors, convulsions, loss of consciousness, respiratory arrest and 

death) and irritation to the eyes, skin, and respiratory tract. Frequent skin contact can 

remove skin oils, resulting in dermatitis.

Section 6. Accidental Release Measures 

_ 

Small Spill and Leak 

Large Spill and Leak 

Absorb with an inert material and put the spilled material in an appropriate waste disposal. 

Contain spill and safely stop the flow. 

Warn personnel to move away. 

Eliminate all sources of ignition. 

Ventilate. 

Absorb with an inert material (sand) and put the spilled material in an appropriate waste 

disposal. 

Dike spill area and do not allow product to reach sewage system and surface or ground water. 

Keep out of waterways. 

Section 7. Handling and Storage 

Handling 

Storage 

Put on appropriate personal protective equipment (see Section 8). Eating, drinking and 

smoking should be prohibited in areas where this material is handled, stored and processed. 

Workers should wash hands and face before eating, drinking and smoking. Do not breathe 

vapor or mist. Do not ingest. Avoid contact with eyes, skin and clothing. Use only with 

adequate ventilation. Wear appropriate respirator when ventilation is inadequate. Do not 

enter storage areas and confined spaces unless adequately ventilated. Keep in the original 

container or an approved alternative made from a compatible material, kept tightly closed 

when not in use. Store and use away from heat, sparks, open flame or any other ignition 

source. Use explosion-proof electrical (ventilating, lighting and material handling) equipment. 

Use non-sparking tools. Take precautionary measures against electrostatic discharges. To 

avoid fire or explosion, dissipate static electricity during transfer by grounding and bonding 

containers and equipment before transferring material. Empty containers retain product 

residue and can be hazardous. Do not reuse container. 

Keep away from heat. 

Keep away from sources of ignition. 

Keep container tightly closed. 

Keep in a cool and well-ventilated area. 

Ground all equipment containing material. 

Keep container dry. 

Keep in a cool place. 

Combustible materials should be stored away from extreme heat and away from strong 

oxidizing agents. 

All efforts should be made to prevent any leaks or spills. Storage tanks containing should be 

engineered to prevent contact with water resources, as this material could contaminate the 

water resources. Surface spills can reach groundwater through porous soil or cracked 

surfaces. The storage tanks should be monitored regularly for leaks. Where spills or leaks are 

possible, a comprehensive response plan should be developed and implemented. 

Section 8. Exposure Controls/Personal Protection 

Engineering Controls Provide exhaust ventilation or other engineering controls to keep the airborne concentrations 

of vapors below their respective threshold limit value. Ensure that eyewash stations and 

safety showers are proximal to the work-station location. 

Personal Protection 

Eyes Safety glasses with side shields. 

Body Flame retardant clothing covering the entire body. 

Respiratory Use a MSHA/NIOSH approved respirator or equivalent at high concentrations. 

Hands Chemical resistant gloves if contact is possible. 

Protective Clothing 

(Pictograms) 

Feet Shoes. 

Personal Protection in 

Case of a Large Spill 

Product Name 

Splash goggles. Full suit. Vapor respirator. Boots. Gloves. A self contained breathing 

apparatus should be used to avoid inhalation of the product. Suggested protective clothing 

might not be sufficient; consult a specialist BEFORE handling this product.
