Terephthalic acid

Guidance on Safe Use

First-aid measures

Eye Contact:In case of contact, flush eyes immediately with copious amounts of water for at least 15 minutes. Get medical attention if irritation occurs.Skin Contact: Wash exposed skin with soap and water.  Get medical attention if irritation develops.Inhalation:  If inhaled, remove to fresh air.  Get medical attention if symptoms appear.Ingestion:  Do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. If large quantities of this material are swallowed, call a physician immediately

Fire-fighting measures

Extinguishing media: Suitable extinguishing media includes water spray (fog), foam, dry chemical or CO2 extinguisher or spray.  Unsuitable fire extinguishing media includes water jet.Hazardous decomposition products:  Decomposition products may include the following materials - carbon dioxides.Unusual fire/explosion hazards:  Fine dust clouds may form explosive mixtures with air.  Handling of this product may generate static electricity, which can present an ignition hazard in some cases.Special fire-fighting procedures:  None identified.Protection of fire-fighters:  Fire-fighters should wear self-contained positive pressure breathing apparatus (SCBA) and full turnout gear.  Dynamic risk assessment is to be used throughout mitigation of the incident.

Accidental release measures

Personal precautions:  No action shall be taken involving any personal risk or without suitable training.  Evacuate surrounding areas.  Keep unnecessary and unprotected personnel from entering. Do not touch or walk through spilled material.  Provide adequate ventilation.  Wear appropriate respirator when ventilation is inadequate.  Put on appropriate personal protective equipmentEnvironmental Precautions:  Avoid breathing dust.  Avoid creating dusty conditions and prevent wind dispersal.  Eliminate all ignition sources if safe to do so.  Water spray or water fog can be used to remove dust particles from the air.  Do not use water jet.  Wetting the spilled material with water spray or water fog will reduce the amount of airborne dust that is created when the material is cleaned up.  Inform the relevant authorities if the product has caused environmental pollution (sewers, waterways, soil or air).Large Spill:  Move containers from spill area.  Approach the release from upwind.  Prevent entry into sewers, water courses, basements or confined areas.  Vacuum or sweep up material and place in a designated labelled waste container.  Dispose of via a licensed waste disposal contractor.Small Spill:  Move containers from spill area. Vacuum or sweep up material and place in a designated labelled waste container.  Dispose of via a licensed waste disposal contractor.

Handling and storage

Handling:  Avoid breathing dust.  Keep away from heat, sparks and flame.  To avoid fire or explosion, dissipate static electricity during transfer by earthing and bonding containers and equipment before transferring material.  Take precautionary measures against static electricity.  The need for additional measures for explosion protection should be evaluated (see NFPA 68--Guide for Venting of Deflagrations; and NFPA 69--Standard on Explosion Prevention Systems).  Wash thoroughly after handling.Storage:  Keep container in a cool, well-ventilated area.  Keep container tightly closed and sealed until ready for use.  Avoid all possible sources of ignition (spark or flame).

Exposure controls / personal protection

Exposure Controls: Occupational exposure controls:  Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits.  If user operations generate dust, fume or mist, use ventilation to keep exposure to airborne contaminants below the exposure limit.Hygiene measures:  Wash hands, forearms and face thoroughly after handling chemical products, before eating, smoking and using the lavatory and at the end of the working period.Personal Protective Equipment: Respiratory Protection:  If dust is generated and ventilation is inadequate, use a respirator that will protect against dust/mist.  If concentration is unknown, a Self-Contained Breathing Apparatus (SCBA) should be used to avoid inhalation of the product.Hand Protection:  The correct choice of protective gloves depends upon the chemicals being handled, the conditions of work and use, and the condition of the gloves.  Most gloves provide only a short time of protection before they must be discarded and replaced.  Because specific work environments and material handling practices vary, safety procedures should be developed for each intended application.  Gloves should therefore be chosen in consultation with the supplier/manufacturer and with a full assessment of the working conditions.Eye Protection:  Avoid contact with eyes.  Use chemical / dust goggles.Skin and Body:  None required; however, use of protective clothing is good industrial practice.

Stability and reactivity

Stability:  The product is stable.  Under normal conditions of storage and use, hazardous polymerization will not occur.Conditions to avoid:  Keep away from heat, sparks and flame.  Take precautionary measures against static discharges.Hazardous decomposition products:  Combustion products may include the following - carbon oxides.  Under normal conditions of storage and use, hazardous decomposition products should not be produced.  

Disposal considerations

Disposal Considerations / Waste Information: The generation of waste should be avoided or minimised wherever possible.  Dispose of surplus and nonrecyclable products via a licensed waste disposal contractor.  Disposal of this product, solutions and any by-products should at all times comply with the requirements of environmental protection and waste disposal legislation and any regional local authority requirements.  Avoid dispersal of spilled material and runoff and contact with soil, waterways, drains and sewers.No information provided on hazardous wastes.
