6610 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.

 

1.0            Purpose

 

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 Material Safety Data Sheet (MSDS).  If none are stated, minimum PPE requirements and control measures are listed within this appendix. 

 

2.0            Scope

 

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.
