Dear Mr. Van Duzer:
This responds to your June 30, 2008 letter requesting clarification of the training requirements
in the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-1 80) as applicable to
temporary hazmat employees. You describe a situation in which temporary employees may
be used intermittently, over an extended period of time.
Generally, a "hazmat employee" is any person who is employed on a full-time, part-time, or
temporary basis and who, in the course of such employment, directly affects the safety of a
hazardous material transported in commerce. A hazinat employee who performs any function
that is subject to the HMR requirements must be trained prior to performing that function
($ 172.702(b)). All personnel are considered hazinat employees at the time they are first
employed to perforin a regulated hazinat f~~nction, even if they are not performing a hazmat
function for greater than 90 consecutive days, and must be properly trained within 90 days of
the first time they perform this function. This provision also applies to contract personnel or
personnel employed directly by a company for periods of less than 90 days, on an intermittent
basis, or over an extended period of time.
In accordance with § 172.704(~)(1), the HMR will permit a new employee to perform
regulated functions and activities prior to the completion of training provided the employee
performs the functions under the direct supervision of a properly trained and knowledgeable
hazmat employee and the new employee's training is completed within 90 consecutive days
from the first time they perforin a regulated function. "Direct supervision" consists of the

supervising employee instructing the new employee how to properly perform the hazmat
function, observing the employee's performance of the function, and being able to take
corrective action with regard to any function not performed in conformance with the HMR.
I trust this answers your inquiry. Please accept my apology for our delay in responding and
any inconvenience this may have caused.
Sincerely,
Lf&-sp Edward T. Mazzullo
Director, Office of Hazardous
Materials Standards

Gentlemen:
We are writing for an interpretation of the hazmat employee training requirements as they
relate to temporary hazmat employees. Specifically, the regulation in question is set forth
in 5 172.204 (c) (1) (i) & (ii) which states that for initial training the employee must
perform hazmat functions under the direct supervision of a properly trained and
knowledgeable hazmat employee and that the training is to be completed within 90 days
after employment or a change in job function.
Clarification is requested as to the timefiame of 90 days. Does this period (90 days)
pertain to consecutive or cumulative days? The employees, in question, usually perform
their duties, intermittently, over an extended period of time. As an example, they might
work 3 days t h s month and not again until 2 months have elapsed when, once again, they
are employed for a few days.
Must they receive hazmat training during their initial employment, in this scenario,
during the 3 days of the first month of employment or are they permitted to work under
the direct supervision of a trained hazmat employee for 90 non-consecutive days?
It is to be noted that when not employed handling hazardous materials these employees
are, no doubt, employed by another company handling non-hazardous materials or
possibly other types of hazardous materials.
If you have any questions I can be reached by phone at (610) 274-0720 or by fax at (6 10)
274-0745. My email address is shipitsafe@,verizon.net.
Thanking you for your attention, I am
