Section 7 - Handling and Storage

HANDLING

Use local exhaust ventilation. Avoid contact with eyes, skin and clothing. Keep container tightly Closed. Further information on storage conditions; Proprietary photo resist film contains approximately 2-4% of 2.3.4-trihydroxybenzophenone (THBP).Which may sublime during

soft-bake or hard-bake processing. THBP has low acute toxicity (LD50>5g/kg). Contact with eyes. Skin or mucous membranes cause irritation. To prevent accumulation of THBP on equipment surfaces and ventilation ducts, preventative maintenance program including regular cleaning should be implemented. Wipe surfaces using an appropriate cleaning solvent when possible. Provide adequate general or local exhaust ventilation during the cleaning process. In situations where this is not possible or where solvent or dust concentrations become excessive. Use an air purifying respirator with an organic vapor/toxic particulate cartridge. When cleaning residual THBP, wear protective gloves and adequate protective clothing to prevent skin contact. Practice good personal hygiene to prevent accidental exposure. Clean all protective clothing and equipment thoroughly after each use.

STORAGE

Storage conditions; Store in original container. Keep away from heat and sources of ignition,
