(a) DesignationYes, ofas collectionan site. (1) Each employer drug testing program shall have one or more designated collection sites which have all necessary personnel, materials,you equipmentmust, facilitiesafter andobtaining supervisionan toemployee's providewritten for the collectionconsent, security,request temporarythe storage,information andabout shipping or transportation of urine specimens to a certified drug testing laboratory. An independent medical facility may also be utilized as a collection site provided the otheremployee applicablelisted requirements of this part are met.
(2) A designated collection site may be any suitable location where a specimen can be collected under conditions set forth
in thisparagraph part, including a properly equipped mobile facility. A designated collection site shall be a location having an enclosure within which private urination can occur, a toilet for completion of urination (unless a single-use collector is used with sufficient capacity to contain the void), and a suitable clean surface for writing. The site must also have a source of water for washing hands, which, if practicable, should be external to the enclosure where urination occurs.
(
b) Security. The purpose of this paragraph is to prevent unauthorized access which could compromise the integrity of the collection process or the specimensection.
(1)
ProceduresThis shallrequirement provideapplies foronly the designated collection site to beemployees secure.seeking If a collection site facility is dedicated solely to urinebegin collection,performing itsafety-sensitive shallduties be secure at all times. If a facility cannot be dedicated solely to drug testing, the portion of the facility used for testingyou shall be secured during drug testing.
(2) A facility normally used
for otherthe purposes,first suchtime as a public rest room or hospital examining room, may be secured by visual inspection to ensure other persons are not present and undetected access (i.e.g., through a rearnew doorhire, notan inemployee thetransfers viewinto ofa thesafety-sensitive collection site personposition) is not possible. SecurityIf duringthe collectionemployee mayrefuses be maintained by effective restriction of access to collectionprovide materialsthis andwritten specimens. In the case of a public rest roomconsent, theyou facility must benot postedpermit against access during the entireemployee collection procedure to avoidperform embarrassmentsafety-sensitive to the employee or distraction of the collection site personfunctions.
(3b) IfYou itmust isrequest impractical to maintain continuous physical security of a collection site from the timeinformation thelisted specimen is presented until the sealed mailer is transferred for shipment, the following minimum procedures shall apply. The specimen shall remain under the direct control of the collection site person from delivery to its being sealed in thethis mailer.paragraph The mailer shall be immediately mailed, maintained in secure storage, or remain until mailed under the personal control of the collection site person.
(cb) Chain of custody. The chain of custody block of the drug testing custody and control form shall be properly executed by authorized collection site personnel upon receipt of specimens. Handling and transportation of urine specimens from oneDOT-regulated authorizedemployers individualwho or place to another shall always be accomplished through chain of custody procedures. Since specimens and documentation are sealed in shipping containers that would indicate any tampering during transit to the laboratory and couriers, express carriers, and postal service personnel do not have accessemployed to the chainemployee of custody forms, there is no requirement that such personnel document chain of custody for the shipping container during transit. Nor is there a requirement that there be a chain of custody entry when a specimen which is sealed in such a shipping container is put into or taken out of secure storage at the collection site prior to pickup by such personnel. This means that the chain of custody is not broken, and a test shall not be canceled, because couriers, express carriers, postal service personnel, or similar persons involved solely with the transportation of a specimen to a laboratory, have not documented their participation in the chain of custody documentation or because the chain of custody does not contain entries related to putting the specimen into or removing it from secure temporary storage at the collection site. Every effort shall be made to minimize the number of persons handling specimens.
(d) Access to authorized personnel only. No unauthorized personnel shall be permitted in
any partperiod ofduring the designatedtwo collectionyears sitebefore where urine specimens are collected or stored. Only the collectiondate site person may handle specimens prior to their securement in the mailing container or monitor or observe specimen collection (under the conditions specified in this part). In order to promote security of specimens, avoid distraction of the collection site person and ensure against any confusion in the identification of specimens, the collection site person shall have only one donor under his or her supervision at any time. For this purpose, a collection procedure is complete when the urine bottle has been sealed and initialled, the drug testing custody and control form has been executed, and the employee's hasapplication departed the site (or, in the case of an employee who was unable to provide a complete specimen, has entered a waiting area).transfer:

(f) Integrity and identity of specimen. Employers shall take precautions
return-to-duty ensurerequirements that a urine specimen is not adulterated or diluted during the collection procedure and that information on the urine bottle and on the urine custody and control form can identify the individual from whom the specimen was collected. The following minimum precautions shall be taken to ensure that unadulterated specimens are obtained and correctly identified:
(1)including Tofollow-up deter the dilution of specimens at the collection site, toilet bluing agents shall be placed in toilet tanks wherever possible, so the reservoir of water in the toilet bowl always remains blue. Where practicable, there shall be no other source of water (e.g., shower or sinktests) in the enclosure where urination occurs. If there is another source of water in the enclosureprevious itemployer shalldoes be effectively secured or monitored to ensure it is not usedhave asinformation aabout source for diluting the specimen.

applicable, forDOT thisagency purposeregulations.
(8d) The collection site person shall note any unusual behavior or appearance on the urine custody and control form.
(9) In the exceptional event that an employer-designated collection site is not accessible and there is an immediate requirement for specimen collection (e.g., circumstances require a post-accident test), a public rest room may be used according to the following procedures: A collection site person of the same gender as the individual shall accompany the individual into the public rest room which shall be made secure during the collection procedure.

If the employee refuses to drink fluids as directed or to provide a new urine specimen, the collection site person shall terminate the collection and notify the employer that the employee has refused to submit to testing.
(3) If the employee has not provided a sufficient specimen within three hours of the first unsuccessful attempt to provide the specimen, the collection site person shall discontinue the collection and notify the employer.
(B
) The employer shall direct any employee who does not provide a sufficient urine specimen (see paragraph (f)(10)(iv)(A)(3) of this section) to obtain, as soon as possible after the attempted provision of urine, an evaluation from a licensed physician who is acceptable to the employer concerning the employee's ability to provide an adequate amount of urine.

released, the collection site person shall measure the temperature of the specimen. The temperature measuring device used must accurately reflect the temperature of the specimen and not contaminate the specimen. The time from urination to temperature measure is critical and in no case shall exceed 4 minutes.
(13) A specimen temperature outside the range of 32°-38° C/90°-100° F constitutes
a reasonsummary to believe that the individual has altered or substituted the specimen (see paragraph (e)(2)(i) of this section).

Since specimens and documentation are sealed in shipping containers that would indicate any tampering during transit to the laboratory and couriers, express carriers, and postal service personnel do not have access to the chain of custody forms, there is no requirement that such personnel document chain of custody for the shipping container during transit. Nor is there a requirement that there be a chain of custody entry when a specimen which is sealed in such a shipping container is put into or takenshe outhad of secure storage at the collection site prior to pickup by such personnel.

(a) Yes, as an employer, you must, after obtaining an employee's written consent, request the information about the employee listed in paragraph (b) of this section. This requirement applies only to employees seeking to begin performing safety-sensitive duties for you for the first time (i.e., a new hire, an employee transfers into a safety-sensitive position). If the employee refuses to provide this written consent, you must not permit the employee to perform safety-sensitive functions.

(b) You must request the information listed in this paragraph (b) from DOT-regulated employers who have employed the employee during any period during the two years before the date of the employee's application or transfer:

(1) Alcohol tests with a result of 0.04 or higher alcohol concentration;

(2) Verified positive drug tests;

(3) Refusals to be tested (including verified adulterated or substituted drug test results);

(4) Other violations of DOT agency drug and alcohol testing regulations; and

(5) With respect to any employee who violated a DOT drug and alcohol regulation, documentation of the employee's successful completion of DOT return-to-duty requirements (including follow-up tests). If the previous employer does not have information about the return-do-duty process (e.g., an employer who did not hire an employee who tested positive on a pre-employment test), you must seek to obtain this information from the employee.

(c) The information obtained from a previous employer includes any drug or alcohol test information obtained from previous employers under this section or other applicable DOT agency regulations.

(d) If feasible, you must obtain and review this information before the employee first performs safety-sensitive functions. If this is not feasible, you must obtain and review the information as soon as possible. However, you must not permit the employee to perform safety-sensitive functions after 30 days from the date on which the employee first performed safety-sensitive functions, unless you have obtained or made and documented a good faith effort to obtain this information.

(e) If you obtain information that the employee has violated a DOT agency drug and alcohol regulation, you must not use the employee to perform safety-sensitive functions unless you also obtain information that the employee has subsequently complied with the return-to-duty requirements of Subpart O of this part and DOT agency drug and alcohol regulations.

(f) You must provide to each of the employers from whom you request information under paragraph (b) of this section written consent for the release of the information cited in paragraph (a) of this section.

(g) The release of information under this section must be in any written form (e.g., fax, e-mail, letter) that ensures confidentiality. As the previous employer, you must maintain a written record of the information released, including the date, the party to whom it was released, and a summary of the information provided.

(h) If you are an employer from whom information is requested under paragraph (b) of this section, you must, after reviewing the employee's specific, written consent, immediately release the requested information to the employer making the inquiry.

(i) As the employer requesting the information required under this section, you must maintain a written, confidential record of the information you obtain or of the good faith efforts you made to obtain the information. You must retain this information for three years from the date of the employee's first performance of safety-sensitive duties for you.

(j) As the employer, you must also ask the employee whether he or she has tested positive, or refused to test, on any pre-employment drug or alcohol test administered by an employer to which the employee applied for, but did not obtain, safety-sensitive transportation work covered by DOT agency drug and alcohol testing rules during the past two years. If the employee admits that he or she had a positive test or a refusal to test, you must not use the employee to perform safety-sensitive functions for you, until and unless the employee documents successful completion of the return-to-duty process (see paragraphs (b)(5) and (e) of this section).
