Task Force and Leadership Changes
• Task Force Changes– S2 Fail-Safe Fault-Tolerant TF has been disbanded.
• While there is value in refining definitions for “fail-safe” and “fault-tolerant,” the TF found that such an effort would likely create more problems (e.g., impact on energetics) than solution. Hence, the TF has disbanded.
• Leadership Changes– Fire Protection TF
• New TF co-leader: Eric Sklar (Safety Guru, LLC) – Existing TF leader: Matt Wyman (Koetter Fire Protection)

Assessment and Risk Evaluation Process• Line items changes to SEMI S10 to solve some clarification
issues and update to latest standards (ISO 12100).• This revision will not affect the Risk Ranking tables of
Appendix 1. These will be done as a separate effort.
* TBA – to be assigned
Committee ActivitiesSubcommittee & Task Force Updates [1/10]
• MESSC (Manufacturing Equipment Safety Subcommittee)
– SEMATECH presented updates on “Energetics in Semiconductor Processing – Best Known Methods and Standardization”
• SEMATECH teleconferences will be scheduled with materials and equipment suppliers to continue gathering feedback on the BKM
– Teleconferences are open to all SEMI EHS Standards TC members– These meetings will also help formulate a TFOF for presentation to the GCS
for approval (June timeframe)» If this can be done, a TF meeting at West
– Obsolete Standards listing in OSHA website• https://www.osha.gov/SLTC/semiconductors/index.html• Obsolete revisions of most standards are shown• SEMI Staff to communicate with OSHA to remove publication dates
and a sentence with link to www.semi.org– Also suggestion to include how our documents are created and used:
industry consensus
BKM – best known method, OSHA – Occupational Safety & Health Administration
Committee ActivitiesSubcommittee & Task Force Updates [2/10]
• S1 Revision TF– [#5623] Revision to SEMI S1, Safety Guideline for
Equipment Safety Labels• Continuing ballot development. This includes addressing the
negative and comments received during the S1 reapprovalballot [#5521]
• TF is requesting guidance from SEMI on how to handle copyrighted figures, tables, and other content used in S1 during the revision process
• TF plans to submit document 5623 for Cycle 5, 2014 voting period.
Committee ActivitiesSubcommittee & Task Force Updates [3/10]
• S2 to Machinery Directive Mapping TF– The TF has completed its initial mapping of SEMI S2 to
the Machinery Directive (2006/42/EC) Essential Health and Safety Requirements.
– The TF plans to publish its work as an auxiliary document.
– Prior to the publication of the auxiliary document, however, the TF would first like to request global EHS committee members to review and provide comments.
• A formal request for EHS committee member feedback will be sent out as soon as possible.
Committee ActivitiesSubcommittee & Task Force Updates [4/10]
• S2 Chemical Exposure TF– Continuing development of ballot 4683C (S2
revisions related to chemical exposure)– Other discussions
• More explanation of surrogate testing• Defining “representative” testing conditions
Committee ActivitiesSubcommittee & Task Force Updates [5/10]
• Hazardous Energy Control Isolation Devices TF– Previously raised LOTO concerns:
• Remote LOTO Challenges – OSHA’s Control of Hazardous Energy does not allow the use of Remote LOTO devices
(remote LOTO = low voltage control circuit isolation) unless it meets the minor service exemptions and the alternate LOTO methods via ANSI Z244.1. What if used not just for minor service but for all potential LOTO.
» Human foreseeable misuse error rate versus the safety circuit failure rate?? • SEMI S2, § 17 (Hazardous Energy Isolation)
– Additional Gaps in SEMI S2 for Chemical LOTO• SEMI S2, § 11 (Interlocks)
– Safety Interlocks: should SEMI S2 specify the need for safety interlock for pressurized chemical/gas access doors?
– Next steps• Edit proposed changes to SEMI S2 Section 17 • Transfer Collaboration with Other Industry Standards Organizations to the
ICRC (e.g. RIA, ANSI, others?)
LOTO – lockout/tagout
Committee ActivitiesSubcommittee & Task Force Updates [6/10]
• Fire Protection TF– Doc 5591 proposed to be balloted in Cycle 3
• Line Item Changes to S2, specifically to: 14.4.4.4, 14.4.4.5, 14.4.5.5, 14.4.5.14
• To be balloted as a delayed revision
– Work plans• Address Negatives from Document #5590 (S14 Re-Approval)• Address Negatives from Document #4495B (Alignment of S14
with S10 Likelihood & Risk Tables)• Tiered Approach for Fire Risk Assessment between S2 and S14.• Future Ballots on Changes derived from responses to re-approval
ballot
Committee ActivitiesSubcommittee & Task Force Updates [7/10]
• S6 Revision TF– Based on ballot results: Realistic worst case release
scenarios and release rate calculations• TF evenly divided so decision made to look at design
requirements that could be used reduce risk factors possibly leading to testing at a lower release rate for S6 validation.
• Design criteria could be incorporated as line items, appendix or RI that would identify controls and risk reduction factors
– Other discussions• PDCB use and low TLV chemistry• Gas detector approval/listing requirement
Committee ActivitiesSubcommittee & Task Force Updates [8/10]
• S22 Revision TF– Additional details of upcoming S2/S22 revision
ballots• Allow disconnect timing method for grounding• Modify UPS output disconnect requirements• Modify the FECS criteria
– Other TF discussion• Arc flash
UPS – Uninterruptible Power Supply | FECS – Fail-to-Safe Equipment Control Systems
Committee ActivitiesSubcommittee & Task Force Updates [9/10]
• S23 Revision TF– Small modification proposal to clarify “energy efficiency
improvement” idea• Idea proposed by NA TF side at Fall 2013 meetings. • Text drafted by TF NA co-leader (Crane) March 2014.• Draft text reviewed, modified and supported by TF Japan co-leader
(Hoshi) March 2014. • Draft reviewed, modified, and supported by NA TF group April 1,
2014.• NA Draft text sent to Japan side of TF April 2, 2014 with a request to
ballot as soon as possible. • NA TF plans to support JA TF with ballot proposal.
– Temperature Control Unit (TCU) Related Information (RI) activity on hold pending volunteer resources
Committee ActivitiesSubcommittee & Task Force Updates [10/10]
• NA Seismic Liaison TF– At the NA Spring 2014 meeting, there were new questions of how and
whether to set a standard appropriately for our industry, roughly summarized as follows:
1) Is there a clear problem statement being “solved” by revising section 19? 2) Should S2 have stricter criteria as a general mater of “improved standard of care”?3) Should S2 contain the strictest criteria (e.g., perhaps based on Taiwan building code)
for all typical production locations?4) Should S2 have a means of deviation or alternate values if equipment will be sold into
more benign regions only, or if the customer accepts such equipment?5) Seismic load force criteria are based not only on installation location, but also on
equipment design characteristics and the placement in buildings. Should any deviations be allowed for these potential variations?
– What appeared to have been general support for the Japan TF plans, has now reverted to some fundamental questions.
– NA TF would like Japan TF to delay balloting while these questions are considered further.
NA EHS Request to Japan EHS
• NA EHS Committee requests the Japan EHS Committee to delay submission of their ballot to change section 19 (Seismic issues) of SEMI S2 to at least after SEMICON West.
• Questions and concerns raised, documented in the NA Seismic Liaison TF report, will still need to be discussed and agreed upon by the NA Liaison TF.
• Discussion from NA EHS TC Chapter meeting:– NA concerns, not only with regard to aligning the force figures with current
industry values, but also on equations used to arrive at these force figures.– NA Seismic Liaison TF is there to assist Japan TF with discussing these issues
now rather than the Document to get rejected during ballot time.– NA EHS Committee request to delay is simply for more time to review
concerns.– It is unclear whether proposed ballot contains the most stringent
requirements (e.g., requirements used in Taiwan).– Concern seems to come from the reasoning for why these numbers are being
changed.
