1. Hazards of Materials (toxicity shaacs) ara included in Safety Manual.
These sheets and control methods will be reviewed by F. Howard vlth each employee in group meetings by April 29.
Each employee will sign statement that review was held. This record will be filed in our Training Record and in industrial hygiene files.
2. Existing environmental conditions (9 materials) are sampled annually and semi-annually on asbestos. This will be done between 4/10/75 and 5/5/75.
Results cooaunicated by letter and presented in regular safety meetings beginning 5/6/75.
Record kept as above.
3. Ran HCBD baselines in January 1975.
4. Currently completing annual physicals. Will be complete by May 5. 1975.

Conducted second asbestos survey for 1975 at Chlor-Alkali II. Monitored three operators Cor asbestos exposure while performing routine duties in the cell area and obtained a stationary sample in the asbestos storage area.
Results were favorable and ranged from .01 to .03 fibers (greater than 5 microns in lenct. per cubic centimeter.
Dow TLV is 2 fibers/cc. - (greater than 5 microns in length)
Good housekeeping and wearing proper respiratory equipment are necessary considerations whenever asbestos is handled.

INTRODUCTION
Made required six moaeh asbestos survey co update status of asbestos levels In the block.
>STKOOOtOGY
Caught four sasiplas using the Bendlx pump (Model C-115) and the oilllpone filter aounted in an open face filcer holder. The sampler was attached co the operators lapel so that the area sampled would be in the breaching zone of Che operator.
Two samples were caught as che operators were making their routine rounds through the plant (These two samples were of thirty-five and eighty-five minutes duration.) The ocher two samples were collected while che operators were pulping cells. (To pulp a cell the operators make up an asbestos-water slurry and pour It into che cells to plug leaks.) These sables were of eighty and forty minutes duration.
RESULTS
The two samples monitoring the operators making their rounds measured .07 and .01 fibers per cubic centimeter greater chan S microns in length. The two samples which monitored the operators pulping cells measured .06 and .40 fibers per cubic centimeter.
CONCLUSIONS
These levels of asbestos remain well within Che OSHA time weighted average of S fibers per cubic centimeter greater than S microns in length and Dow's goal of 2 fibers per cubic centimeter. Sampling will continue on a six month basis.
RECOMMENDATIONS
Since che operators must handle dry asbestos co form che pulping slurry there are several precautions that must be followed. The operators are required to wear the MSA Comfo Respirator (type BM 2301) with che asbestos dust cover (type BM 2301), rubber gloves and paper suits.
The asbestos should always be handled wet (the sack should be vet down even before cutting open). Practice good handling techniques to avoid spilling asbestos. All efforts should be made to prevent asbestos from becoming airborne when handling. Net asbestos on tools and clothing should not be allowed to dry and eventually become airborne.
After che job is completed asbestos waste and empty asbestos sacks should be sealed and labeled in impermeable bags and containers. The asbestos should never be blown or shook off the contaminated suits. It should be vacuumed and placed in the proper designated containers.
Always wash hands after handling asbestos and never carry cigarettes or candy in pockets while working with asbestos.
The last point is to always be on the alert for problem areas, report them to supervision and have che area monitored if it la suspect.

CHLOR-ALKALI II
Caught no samples uhil* operators ware pulping ceLIs with the 3endi.\ pump set at 2 licars per minute. The samplas ware collected from the breaching zone, with the sampler planed on the operators lapel.
To pulp a cell the operators make up an asbescos-wacer slurry and pour it Into the cell to plug leaks. The operators mix dry asbestos with water In a box to fora the slurry. The asbestos should always be handled wee from the tine the bag Is opened until the slurry Is completed. The operators wore required MSA Cooio Respirators with the asbestos dust covers (Type BM 2301
The two samples varied from .046 to .79 fibers per cc greater chan 5 eicrons 1= length. This is well below the O.S.H.A. standard of S fibers per cc and Dow's guideline of 2 fibers per cc.
The notable difference between the two samples could be due to Che different procedures employed by the operators. Operators must be informed of the sanni= results and must also be made very conscious of the hazards involved with handling asbestos.
Safe operating procedures should be emphasized to keep exposure to a ninimun. Wetting che asbestos thoroughly and wearing the proper breaching equipment when mixing che slurry also is most important. When using the respirator it is imperative that Che asbestos dust cover be fitted on it. Another important precaution is the necessity for being extremely careful not to get slurry on clothing which will dry out and give off airborne asbestos particles. Partial! used bags of asbestos should also be handled with caution and kept sealed in plastic to prevent airborne asbestos particles.
