Hazards and Protection.
Storage
Keep in a tightly closed container. Store in a cool, dry location, way fron incompatible materials.
Handling
Only trained individuals should handle this chemical or its containers. For laboratory use only. Use approved safety equipment when handling.
Protection
Use of garments to protect workmen from irritation due to contact with phthalic anhydride which is used in the manufacturing process of phthalic acid esters; gloves should be used to prevent contamination of the hand and lower arm. Synth of phthalates require good ventilation in order to minimize contamination of air with phthalic anhydride or alcohols. There may be also some need for skin protection. Handling mineral acids used as catalysts requires ordinary precautions.
Respirators
NIOSH/MSHA approved respirator.
Small spills/leaks
Evacuate area. Wear appropriate, approved equipment. Ventilate area. Absorbe on vermiculite or sililar material. Sweep up and place in an approved contaner to hold for disposal. Wash contaminated surfacts to remove any residue.
Stability
Stable at normal temperatures and pressures.
Incompatibilities
Strong oxidizing agents.
Decomposition
Toxic fumes.

Fire.
Fire fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use agent most appropriate to extinguish fire.
Fire potential
Combustible
