MATERIAL SAFETY DATA SHEET Dichloromethane MSDS Number: BDH-120 Page 4 of 9 7. HANDLING AND STORAGE NORMAL HANDLING: (Always wear recommended personal protective equipment.) Ensure adequate ventilation. Do not allow product to contact skin, eyes and clothing. Do not breathe vapours. Keep away from fire, sparks and heated surfaces. We shall ensure, so far as is reasonably practicable, that any revision of this Data Sheet is sent to all customers to whom we have directly supplied this substance, but must point out that it is the responsibility of any intermediate supplier to ensure that such revision is passed to the ultimate user. Under this proposal “Material Safety Data Sheets” will be known as “Safety Data Sheets”. The format of Safety Data Sheets will also align with international U.N. standards. Heritage-Crystal Clean’s SDS’s will be revising Safety Data Sheets to meet these new format standards as they go into effect.
