New: Controlled Substance In-House Disposal Procedures

The disposal process is the final action necessary to ensure proper management of controlled substances.  As of April 2013, EHS has been approved by the Drug Enforcement Administration (DEA) to dispose of controlled substances through the use of an approved procedure.  Details on how to dispose of controlled substances used in research can be found on the EHS website.

Each licensed researcher is ultimately responsible to ensure controlled substances are properly disposed of and all necessary disposal forms are completed and submitted to the appropriate agency. To dispose of outdated, damaged, or otherwise unusable or unwanted controlled substances, contact Bill Murray at 335-4624.

If you have questions about chemical storage in labs, you can contact Rick Byrum or LuAnn Hiratzka.

Answers

  1. b.  Flammables should be stored in a flammables cabinet.  Not-intrinsically reactive or flammable liquids like chloroform may be stored in the flammables cabinets with non-reactive flammables. Ethanol should be kept away from flames.  Cold rooms can recirculate vapors so ethanol and other chemicals that can release hazardous vapors should not be stored in cold rooms.
  2. c.  Acids may be stored in the acid cabinet side under the fume hood but oxidizing acids should be segregated from other acids by placing them in a separate secondary container. Acids can corrode metal shelves.  Acids should be segregated from bases.
  3. c.  Not intrinsically reactive or flammable solids can be stored on a shelf together; however, do not store liquid chemicals above solid chemicals to prevent undesired reactions if the liquids were to leak onto the solids below.
  4. a.  Yellow color codes most often represent reactive and oxidizing agents so should be kept away from flammables and combustible materials.  Red is normally flammable and blue is normally health hazard/poison.
  5. c.  Hydrochloric acid is best stored with other compatible inorganic acids. TEMED is an organic base. Bases should not be stored with acids.  It is very important to keep cyanide chemicals away from acids.
  6. a.  Tetrahydrofuran is flammable so is best stored in a flammables cabinet.  Since it requires periodic testing for the presence of peroxides, it is best to keep it near the front of the cabinet.  If lost in the back, it may be forgotten and could develop a peroxide concentration that would cause it to become shock-sensitive.  Also, THF should be kept away from heat and oxidizers such as ammonium nitrate.

Responsibilities of Principal Investigators

Due to a recent incident of noncompliance, the Institutional Biosafety Committee (IBC) would like to remind Principal Investigators (PIs) of their obligations in managing their research projects.  PIs are faced with many regulatory requirements that must be addressed prior to beginning work on and during the management of their research.   In response to an ever increasing regulatory burden, many PIs delegate to subordinate staff the responsibilities for completing the paperwork required for obtaining regulatory approvals and for post approval implementation of required regulatory processes.  

While such delegation of responsibility is appropriate, it is important to emphasize that PIs must properly supervise subordinate staff as they carry out these responsibilities.   Moreover, it goes without saying that PIs must perform detailed reviews of all regulatory documents prepared by subordinate staff before signing and submitting them for internal review.  Ultimately, it is the PI who will be held responsible for the information contained in the regulatory documents submitted and for the implementation of the required regulatory processes once a research project is under way. 


OSHA Concludes Fatality Investigation at San Francisco VA Medical Center Research Laboratory (Originally published by OSHA)

OSHA has issued a notice of unsafe and unhealthful working conditions to the San Francisco Veterans Affairs Medical Center after concluding its investigation into the death of Richard Din, a research associate at the center's research laboratory in April 2012. The notice consists of three serious violations for failing to protect laboratory workers researching Neisseria meningitidis, a bacterium that can cause meningitis.

The three serious violations include failure to require workers to use a safety enclosure when performing microbiological work with a viable bacteria culture; provide training on the signs and symptoms of illnesses as a result of employee exposure to a viable bacteria culture, such as meningitis; and provide available vaccines for workers potentially exposed to bacteria.  A serious violation occurs when there is substantial probability that death or serious physical harm could result from a hazard about which the employer knew or should have known.

Radiation Survey Meter Basics

Survey Meter

If you use radioactive materials, you are probably familiar with Geiger counters. You may know they are used for conducting radiation surveys, but you may not know some of the finer points of using these instruments, or all the information they can provide.  Prior to using a radiation survey meter, the following checks need to be performed to ensure it is functioning properly:

  1. Check the calibration date of the meter.  If the date of the last calibration is not within one year of the date you are using the meter, you cannot use it for a documented survey.  You can contact EHS to have your meter calibrated, and we may be able to provide you with a loaner instrument while yours is being calibrated.
  2. Check the battery.  Most survey meters either have a switch position or a button labeled ‘Battery Check’ for this purpose.  When the unit is set to ‘Battery Check’, the meter will display whether or not the battery has sufficient charge.
  3. Check the meter response by turning it on and holding the detector up to the check source affixed to the side of the meter.   The meter reading should be very close to the value written on the calibration sticker in the “Reads” blank under ‘Dedicated Check Source’.  If not, contact EHS so the meter can be checked out and re-calibrated, if necessary.

In most cases, people doing surveys with a Geiger-Mueller (GM) detector are looking for a simple yes or no answer to the presence of radioactivity above background.  However, the efficiency values listed for several different radionuclides on the calibration sticker can help you quantify radioactivity to some degree.  Example:  You are surveying a lab bench where P-32 is being used and get a reading of 52,000 counts per minute (cpm) on your meter.  To convert this to activity, which is expressed in disintegrations per minute (dpm), you will need to use the efficiency value listed for P-32.  By looking at the side of the meter, you note an efficiency value for P-32 of 28.5%, as an example.  So the activity of the contaminated area would be 52,000 cpm / .285 =  182,456 dpm.  You can then convert dpm to uCi as follows:  182,456 dpm / 2.22E6 dpm/uCi = 0.082 uCi.

Contact EHS at 335-8501 for any other questions you may have regarding use of survey meters.


UCLA Lab Death Update

An article in our March 2012 Lab News reported on an accident in which a Research Assistant was killed more than four years ago while she was working in the laboratory of a UCLA chemistry professor.

On Friday, April 26th, the professor was ordered to stand trial on felony charges. The professor is charged with willfully violating state occupational health and safety codes and faces up to 4 ½ years in prison, if convicted. The LA Times story can be found here.
