Appendix T5 Chemical Personal
Protective Equipment and Associated Control Measures |
||
|
|||
Jefferson Lab has determined that working with chemicals carries an unmitigated Risk Code >2. At a minimum all tasks requiring chemicals are discussed with the supervisor prior to commencement of work. An Operational Safety Procedure (OSP) is written for work considered to be Risk Code >2 in accordance with ES&H Manual Chapter 3210 Work Planning, Control, and Authorization Process. |
Jefferson Lab requires that
everyone working with chemicals read and follow the
recommendations/requirements for personal
protective equipment (PPE) and control measures
listed on the chemical’s Safety Data Sheet
(SDS). If none are stated, minimum PPE requirements and control measures are
listed within this appendix.
PPE does not take the place of
engineered and administrative control measures; rather it is used in
conjunction with them to increase the safety of everyone at Jefferson Lab.
This appendix applies to
Jefferson Lab’s minimum chemical PPE requirements. Always refer to applicable Work
Control Documents (e.g. OSP and/or Task Hazard Analysis) for guidance on PPE
required for your work. See also: ES&H Manual
Chapter 6620 Personal Protective Equipment Program
for guidance regarding the use of “basic PPE.”
This
appendix’s process steps are used in coordination with ES&H Manual
Chapter 6610 Chemical Hygiene Program.
NOTE: Management authority may be delegated at the discretion of the responsible manager.
3.1
Qualified Chemical Workers
·
Inspect PPE before and after use. Dispose
of damaged items appropriately.
·
Wear appropriate PPE while working with chemicals.
·
Utilize hazard controls in accordance
with manufacturer instructions and/or area work control documents.
·
Submit a Facilities Management Work
Request for repair of damaged or malfunctioning control
measures.
· Contact the Industrial Hygienist regarding appropriate chemical PPE and other control measures.
3.2 Supervisor/Subcontracting Officer’s Technical Representative (SOTR)/Sponsor
· Ensure qualified chemical workers are trained on appropriate PPE requirements.
· Ensure appropriate PPE and control measures are available to chemical workers.
· Retain an up-to-date permeation/degradation guide for hand protection for all gloves types used at Jefferson Lab.
· Retain an up-to-date permeation/degradation guide for body protection used at Jefferson Lab.
· Maintain and provide respirators/SCBAs equipment and training as required.
· Ensure appropriate eye protection, glove selection, and other identified chemical PPE is made available through Jefferson Lab Webstock or in the stockroom.
· Obtain Industrial Hygienist approval prior to stocking new types of chemical PPE.
All of the following is
required when working with chemicals, or within
an area designated as a chemical laboratory.
·
Proper work clothing,
·
Substantial closed
toe/heal shoes (i.e., no sandals), and
·
Tied-back hair.
