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 beginning. 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 Labs 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 to a
task-qualified TJNAF employee 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. Lead
worker training must be repeated on an annual basis when a workers lead
exposure has been determined to be at or above the Action Level of 0.3 mg/m3,
this is determined through Industrial Hygiene air monitoring.
·
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, Technical Representative (TR) and Sponsors
· 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 safety data sheet
(SDS), if available.
Step 2:
Ensure
the work plan abides by the SDS 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) 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.
o Lead shielding that has been mixed
with heavily oxidized unpainted shielding must be wet-wiped after HEPA
vacuuming to further reduce lead being distributed into the air. Contact IH for
evaluation.
·
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 to Industrial Hygiene 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.
