VC1 STANDARD
EFFECTIVE 1/2/7 5
The A-20C grout has carefully reviewed the new VC1 Standard.
This review -was supplemented with' information gained from a recent
ORC meeting with OSSA officials in Washington (L. D. MacAdain will
issue trip report) . Objectives of our reviews were to.: 1)
develop a basic understanding of the standard,
2) specify
what we believe is intended by the standard, and 3) define
actions needed no comply. You are asked no critically review
our summary of the standard and action elements for adequacy
(attached) . Recognizing that this is only the first step, I
propose than we hold a meeting at Niagara in November to finalize
our plans for complying with the standard and to reach agreement
on the key assumptions. Any comments' or assistance you can
provide refers then -would be helpful.

Emergency is loosely defined as a massive release of VC1. vfe internret this to mean those situations such as a rupture of storage and feed vessels,' where large amounts of VCl can be lost. This part of the Standard appears to allow interpretation, i. e. performance versus specification language.
See comment (a-2) above. Note stipulation on further processing at temperatures 'which could result in-release of VC1. Can we guarantee that no VCi is released during Turbo processing cr fabric drying?

Twice daily atmospheric analysis via MSA tubes and gas chromatography has been a continuing program in the Pilot Plant since startup in February, 1974. However, our current methods for analyzing VC1 are not sufficiently accurate to monitor at the "action level" of 0.5 ppm or even an the "permissible- exposure limit" of 1 ppm. An acceptable method (discussed below) will be very expensive to implement if used -as often as is our current practice. We will develop a proposal for monitoring the Pilot Plant by next month. It is essential that all parties be in agreement with, this proposal before year-end.
(1) This will be done for both the Pilot Plant and Building 411
Technical Laboratory.
(2) We will establish a program for determining exposures for each employee in the Pilot Plano. Our intention is to show that this program will not be required in the Technical Laboratory.
(i) The 'Government requires at' least monthly monitoring where any employee is exposed in excess of 1- ppm. In cases of fabricators where 7C1 level will likely be < 0.5 ppm or PVC manufacturers where VC1 level will likely exceed 1 ppm on a routine basis, once/month monitoring probably
serves the Government purposes.

We assume this includes those circumstances involving "hazardous operation". It has been our practice to require proper protective equipment until we can confirm negligible VCl in the atmosphere. The only change we will make in current procedures is to use a more accurate mevhod of measuring VCl.
At this time we do not have the capability o measuring VCl in air a t th e a c c ur .cy cf - 5 0% f r om 0.25 through 0.5 ;pm required by the Standard. f ;e Mira n I?. analyzer can measure down po 0.7 ppm but our experience v .th ahe portable unit has been the ; an as subject to electrical n use at lev; rantes in our area. Our intent is to use the continuous analyzer to monitor proces equipment at some pre-set higher levs to alert operations to potential
hazards which could result in buildup of VCl. It is improbable, that these readings could ever be correlated with the very low "action levels" of 0.r> ppm.

and improved ventilation, by year end will permit consistent operation at exposure levels below the permissible limit. If this turns out to be the case, then we will not be required to formalize plans for future programs to reduce VCl level.
Respiratory protection requirements are clearly stated. What is lacking is a statement of the specific respirators which meet these requirements. This was pointed out in the ORC meeting and the OSHA officials replied that acceptable air purifying respirators would be designated by the compliance date. It remains to be seen whether these respirators will be available in time.
We do not agree than the use of respirators at VCl exposures of < 25 ppm curing 1975 should be left ro the discretion of the employee.

An operational plan for handling emergency situations is currently being developed. The scope of this plan will be expanded to encompass procedural action required for all "hazardous operations", including those developed in Sections (g) and (h) of phis Standard.
The current training program in the Pilot Plant includes:
o Operating procedures are detailed and operators are given extensive training.
e Protective equipment including self concerned breathing apparatus is provided and operators have' been instructed in their use by the plant Safery Group.

The existing program will be reviewed end undated to comely with this section of phe Standard. The complete program will be documented and reviewed with operators by /ear end.
Vfe have initiated a medical program for A-20C personnel and physcial examinations meeting this standard were completed to establish a base line healzh profile. The Niagara Plant physician reviewed the examination results with individuals upon request; no problems related to VC1 toxicit w?ere uncovered. The next annual examination, is scheduled for April,`1975.
All entrances to the Pilot Plant facility will be identified with the specified sign.
Procedures.detailing proper isolation/ identification of areas containing "hazardous operations" will be formalized and posted.
All drums/containers containing waste contaminated with VC1 will be labelled as specified. A list of A-20C wastes meeting this classification will be compiled and posted. we wj.ll review with S a F the need to label container of A-20C filter cake and dried polymer which have been analyzed as being free ox /Ci monomer.
