This page
has information for agencies on air-monitoring for lead exposure.
Earl has designed a "chain of custody" form, a form for "air
sampling", as well as a 'protocol form".
Introduction
To
continue the effort to train weatherization staff regarding lead save
work (LSW) practices and assist with standardized methodology in
implementing these practices in order to obtain a permanent NID, we
have developed a series of instructional guidelines and forms which
will allow crew to document specific activities relating to practices
while working on target housing. The guidelines will impart
uniformity throughout the network when preparing for and actually
collecting the samples. Information will be entered on the face of
the forms by hand, so as not to appear like it is a computer generated
form letter. LSW practices, both specific to the task and common to
all tasks are listed on the back. The back of each form has four
sections; 1. Information on the specific practice. 2 Clean up and
Disposal 3. Work Area Shut Down, 4. Notes
In addition to the 9
specific practices considered in the Lead-Safe Weatherization Practice
document develop by ATC Associates for DHCR, we have evaluated
additional activities which may pose a significant exposure to lead
dust to both the worker and clients. The additional activities to
investigate are: Replacing Furnace Filter; Repair/Add/Replace
Ductwork, Replacing Furnace; Replacing HEPA Vacuum filter.
Upon reviewing data from
7 agencies we noted that there were a small, yet significant number of
results that came back with levels above OSHA’s PEL. After observing
the way these samples were gathered, ie LSW practices, it was
determined that the operator was either 1.“baring down” on the tool,
2. improperly mounted air sampling, and therefore exposing them self
(and Personal Pump) to the highest level of dust, or 3. not adding
detergent (wetting agents) to the misting water. Therefore we have
added “Work outside of the breathing zone” to all specific practices.
We also added to “mist debris prior to rolling up plastic” to all
specific practice listings.
