In fairness to those who must move these items, we ask that you exercise care and good judgment by taking the time to carefully survey and decontaminate equipment that may have been in contact with potentially hazardous biological, chemical or radioactive materials. A completed Procurement / EHS tag, Certification that Property is Free from Hazards must be attached to each piece of equipment to be moved after it has been surveyed and--if needed-- decontaminated. This responsibility rests with the owner/user(s) of the equipment. No equipment is to be moved unless it has been properly, thoroughly cleaned and certified.
Wear a lab coat, appropriate gloves and eye protection. Disconnect all electrically powered equipment before cleaning or servicing. Tag all wastes with a properly completed EHS Waste Tag.
Drain and collect pump oils or similar fluids for disposal by EHS. Remove replaceable batteries. In water baths, incubators and other temperature regulated devices--remove and set aside all mercury thermometers. EHS strongly encourages the minimization of mercury and will accept all mercury and mercury thermometers for disposal--free of charge.
Examples include: Contact with human blood and body fluids, primary human cell lines, crusty E. coli deposits, etc. Prepare a fresh 1:10 solution of bleach and water, and then thoroughly wipe down all exposed surfaces. Pre-clean soiled areas or deposits with a warm detergent and water solution.
Examples include: Ethidium bromide residue spilled phenol/chloroform, salt deposits, etc. Prepare a mild detergent and water solution, and then thoroughly wipe down all exposed surfaces. Repeat or soak, as necessary. Do not use bleach or other corrosive-cleaning agents. Special chemical hazards may require specific precautions--contact EHS first.
Survey internal and external surfaces for removable contamination using swab tests. Use a decontamination product like Count Off‚® Document your results in the radiation safety records of your lab. All surface contamination must be < 220 dpm/ 100 cm2. For radioactive iodine contamination, the limit is 20 dpm / 100 cm2. If you cannot reduce contamination to below this level, please contact the Radiation Safety Officer.
