U local exhaust ventilation. Avoid contact with eyes, skin and clothing. Keep container tightly
Clod. 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 cau 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 d
ust concentrations become excessive. U 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 u.
STORAGE
Storage conditions; Store in original container. Keep away from heat and sources of ignition, Storage area should be cool dry well ventilated out of direct sunlight
