Appendix T1 Lead Work
Requirements |
||
|
|
|||
|
Jefferson Lab has determined that working with lead carries an unmitigated Risk Code >2. At a minimum all tasks requiring lead are discussed with the supervisor prior to commencement. An Operational Safety Procedure (OSP) is written for any work considered to be Risk Code >2 in accordance with ES&H Manual Chapter 3210 Work Planning, Control, and Authorization Process. |
1.0
Purpose
This appendix provides Jefferson Lab’s minimum
requirements when working with lead including: pre-work planning and actual work activities (e.g.: movement of lead
bricks, machining, soldering, welding,
and lead based paint abatement).
2.0
Scope
This procedure defines additional mitigation measures for activities involving lead, over and above standard protecting measures.
The process steps for this procedure coordinate with ES&H Manual Chapter 6680 Lead Handling Program
3.0
Responsibilities
NOTE: Management authority may be delegated at the discretion of the responsible manager.
3.1
Qualified
Lead Worker
·
Complete and maintain
appropriate training (SAF 136 Lead
Worker Training, or equivalent) and medical monitoring requirements.
·
Ensure pre-work
planning is adequate. Request a hazard
evaluation if lead exposure is considered to be an issue.
·
Perform work
activities within the hazard controls.
3.2 Supervisor/Subcontracting Officer’s Technical Representative (SOTR)/Sponsor:
· Assign only Qualified Lead Workers to lead work.
· Perform lead work/area hazard evaluation and determine required mitigation.
4.0
Process Steps
Unless otherwise stated, only Qualified Lead Workers may perform the process steps outlined below.
|
When working with lead, associated hazard issues should be taken into consideration (i.e. heavy lifting) due to the weight of the material. |
Step 1:
Review the associated material safety data
sheet (MSDS), if available.
Step 2:
Ensure
the work plan abides by the MSDS’ requirements and mitigates the hazards
adequately.
Step 3:
Request
a hazard evaluation from Industrial Hygiene if monitoring, respirator, or other
mitigation is recommended but is not called out in the work plan. (Equivalent or superior methods may already
be in-place.)
|
The following activities (or similar) are prohibited when working with: |
|
|
· Eating or chewing · Drinking |
· Using tobacco products · Applying cosmetics or lotions |
|
Do not take these items into areas where lead is handled or stored. Thoroughly wash all exposed skin surfaces (e.g.: hands, face, arms) with soap and warm water prior to partaking in any of these activities. |
|
4.2.1 Movement
of Lead Brick(s) and Sheeting
|
NOTE: Contact Industrial Hygiene to perform a
hazard evaluation regarding appropriate/adequate options for the following
situations. 1. Movement of uncoated bricks. 2. When airborne exposure to lead is above the Permissible Exposure Limits[1] (PEL) (whether or not a respirator is worn) as a changing area, equipped with a separate storage facilities to protect street clothes from cross-contamination, is required. |
·
Less than
or equal to (<) 10 Bricks
o
Don appropriate PPE – See ES&H Manual Chapter
6680 Appendix T2 Lead Handling Personal Protective Equipment (PPE) and Other Related
Personal Protective Measures
o Clean-Up – See ES&H Manual Chapter 6680 Appendix T4 Lead Clean-Up, Disposal, and Recycle Procedures
o Same requirements as <10 above and
o “Lead-only” HEPA Vacuum obtained from Industrial Hygiene.
o
Respiratory Protection, in
accordance with Industrial Hygiene hazard evaluation – See ES&H Manual Chapter 6630 Respiratory Protection Program.
o
Air Monitoring –
Contact Industrial Hygiene for a determination.
·
Less than or equal to (<)
12-inch Square Sheeting (for greater amounts see
Industrial Hygiene)
o Don
appropriate PPE –
See ES&H Manual
Chapter 6680 Appendix T2 Lead Handling Personal Protective Equipment (PPE) and Other
Related Personal Protective Measures
o
Pre-Work Wet-Wipe – In accordance with instructions
provided by Industrial Hygiene.
Jefferson Lab has determined that machining of lead carries
an unmitigated Risk Code >2 because it results in the generation of dust,
and particulates. An Operational Safety
Procedure (OSP), minimally reviewed by Industrial Hygiene and approved by the Supervisor, is required to ensure
appropriate mitigation for this type of work.
Step
1:
Develop an OSP per
ES&H Manual Chapter
3310 Operational Safety Procedure Program and include:
· Minimum PPE requirements.
· Ventilation - HEPA
filters required obtained from Industrial Hygiene.
· Air monitoring.
· Isolation of the work
(minimally cordoned-off).
· Required hazard postings.
· Post-work
decontamination procedure.
Step
2:
Abide
by the requirements of the OSP when performing the work.
·
Don appropriate PPE – See ES&H Manual Chapter
6680 Appendix T2 Lead Handling Personal Protective Equipment (PPE) and Other
Related Personal Protective Measures.
· Work
in a Well-Ventilated Area - Avoid
breathing in smoke or fumes generated during work. Request a hazard evaluation from Industrial
Hygiene to ensure ventilation is adequate.
· Clean Soldering Benches and Work Surfaces (after use or weekly,
whichever comes first). (See ES&H Manual Chapter
6680 Appendix T4 Lead Clean-Up and Disposal Procedures.)
· Wash Hands with soap and water upon completion of work.
Lead welding is not authorized at Jefferson Lab.
4.2.5
Lead-Base Paint
Abatement - Lead abatement activities are only authorized to be
performed on behalf of Jefferson Lab by an individual, licensed by the State of
Virginia. Proof of licensing must be
submitted prior to commencement of work.
Jefferson Lab considers lead-based paint abatement activities
to be a modification to existing facility and requires a Facility Design or
Modification Review (see ES&H
Manual Chapter 3110 Facility Design and Modification Review).
