Appended hereto is the FEtAL draft for the above referred to Chemical Safety
Data Sheet. The text contains a number of revisions suggested by member* of the
Caamlttee and producers and usera of vinyl chloride.
In order to comply vlth our publication schedule it is earnestly requested
that all cocmeats and corrections he placed at our disposal not later than October 23.
J Copies of the draft are being sent to .those producers end users vfco have re
ceived copies of the previous draft in the hope that those paragraphs on vhieh they
had commented might.be re-examined, and if necessary, deleted or corrected.
The producers and users are The Dov Chemical Company, Tlx: Firestone Plastics
Company, B. F. Goodrich Chemical Company, Goodyear Tire 4 Rubber Company, Inc. and
Hangatuck Chemical Division, United States Rubber Company.
The vriter appreciates very irnch the cooperation of all concerned In completing
tbe present draft. .

SUMMARY
Vinyl chloride it u highly volatile extremely PLAMMABL2 compressed gu vhich la
ordinarily-'handled in liquefied form under pressure. It hae a mild aneatbetic action
t
in concentrations shore 500 ppn.and the vapors are irritating to the eyes.
%
Precautions necessary in handling the material are detailed.in the body of the
Safety Oats Sheet. Key points to consider for safe henaung include:
1. Keep avsy from heat, sparks and open flame.
2. Provide adequate ventilation.
.
3. Ground equipment and containers before discharging to reduce- danger of ignition
from static sparks.
4. In discharging do sot heat containers above 50C. (122F.). Ho beat should be
ft l 1 V A IIM 1 IM M O liV fU fO rfN I /
applied to tank cars.
5. All equipment etc. should be of steel and have a designed vorklng pressure of
at least 100-150 psl.
6. In the event of accidental leaks, spills or vbenever excessive vapor concentrations
may be encountered only personnel equipped vith approved respiratory protection
should be permitted In the contaminated area. *
7> Chemical safety goggles should be vom when' discharging containers or tank cars .
or vbenever there is a danger of the' liquid or saturated vapor casing in contact
vith the eyes.
8. Waste disposal should be avay from any source of ignition. Dilute phenolic residues

2.3 Hazardous Properties
2.3.1 Health Hazards (See 8. Health Hazards and Their Control)
Vinyl chloride presents no very serious problem in general handling aside from the
risk of fire and explosion. The presently accepted upper limit of safety as a health
hazard Is 500 ppm.
2.3.2 Fire Hazard
Vinyl chloride vapors form flappable mixtures with air at all temperatures shove
-78C. (.108.4F.).

must be of metal or ether material, suitably treated if necessary, which will nert cause *
formation of any aeetylides. A good practice is to dismantle all valves for inspection
before each loading. Approved cylinders include ICC - 4B300 and ICC - lfBA300, ICC -
