Type/Signs of overexposure How you can protect yourself 5. Photo/Employee taking test (no sound) (Music up full to establish, then down) The topic today is lead, an element found in nature, and one of the ingredients we use to make products here at the Aberdeen chemical plant. We want you to know what lead is, where it is found in our plant, and how it can affect your health. You'll also need to know the signs of overexposure, and how you can protect yourself from unnecessary exposures to lead. At the end of this program, we'll give a written test, to make sure we all understand the important things about lead-related health problems, and what we need to do to prevent them. Aberdeen Lead Exposure 10 February 1983 Page 2 6. Type/Limits on your exposure to lead 7. Photo/Two people talking 8. Type/Where we fit in 9. Art/Tombstone To insure your health and safety, Conoco Chemicals Company has established strict limits on your exposure to lead. Our rules generally follow the standards called for by OSHA--that's the federal Occupational Safety and Health Administration--but our regulations often exceed their standards. Lift-- -On ' .i.-.Mi. *J l We're all working to keep on-the-job exposures to lead as low as possible. That's why we need everyone's help and support. This program will help explain what Conoco Chemicals is doing and where each of us fits in. The reason we are limiting exposures to lead is because excessive exposures can cause serious illness, or even death. SAL 000C35465 Aberdeen Lead Exposure 10 February 1983 Page 3 10.

Type/Lead can damage: o Nervous system o Kidneys o Reproductive organs o Blood chemistry Lead is normally a dense, silvery metal, but here at our plant you generally find it in powder form. Lead can enter the body by breathing it in... ...or by swallowing it on your food. Your body has the ability to eliminate or pass off only a certain amount of lead each day, and repeated exposures above that level can cause the body to store the excess lead in the bones and other tissues. As the concentration of lead steadily increases, it can damage the nervous system, kidneys, reproductive organs and blood chemistry. SAL OC.OC35466 Aberdeen Lead Exposure 10 February 1983 Page 4 15. Type/Signs of over-exposure: o Stomach pains o Loss of appetite o Nausea o Metallic taste Early signs of overexposure to lead--which may vary depending upon the amount of exposure--are stomach pains, loss of appetite, nausea and a metallic taste in the mouth. 16. Type/Signs of over-exposure o Constipation o Weakness or tiredness o Nervous irritability o Slight tremors Other signs of overexposure to lead are constipation, excessive weakness or tiredness, nervous irritability and slight tremors. 17.

Type/Reproductive system damage 26. Art/Male silhouette typeover/Decreased sex drive, impotence, reduced sperm count, sterility One of the results of overexposure to lead is a condition called "wrist drop"--where it's difficult or even impossible to hold the wrists out straight with the arm when the arm is extended. Damage to the nervous system is particularly serious because nerve cells don't have the ability to repair themselves. The kidneys may also be damaged by excessive exposures to lead over long periods. And by the time kidney damage can be detected, it's too late to correct the condition. Overexposure to lead can also affect the human reproductive process. In men, possible effects include decreased sexual drive, impotence, reduced sperm count and sterility. SAL 000035469 Aberdeen Lead Exposure 10 February 1983 Page 7 27.

Type/Where lead is found Now that you know how dangerous lead can be, let's take a look at where it's found in the plant. 30. Photo/Truck V 31. Photo/Truck being unloaded Chemical compounds containing lead come into the plant by truck... ...on pallets, which are unloaded and stored in the raw materials warehouse. These materials are used primarily on the compound lines and in the color weigh room. SAL 0c,00354 Aberdeen Lead Exposure 10 February 1983 Page 8 32.

Type/Jobs which may bring you into contact with lead compounds: 35. Repeat slide #31 36. Photo/Storing 37. Photo/Testing lead Some of the specific jobs that may bring you into contact with these lead compounds are: ...unloading raw materials containing lead from trucks... ...storing them in the raw materials warehouse... ...quality testing raw materials containing lead...

At the compactor, too, you can come into contact with lead. In addition, mill operators may periodically contact lead-containing "pre-blends" during product changes and maintenance work.

Photo/quad split of slide #s 40, 41, 43, 45 Okay, now you know lead is bad for you, is'' where it's found in the plant, and how you can be exposed to it. What, then, are we doing to prevent you from being overexposed to lead? 47. Type/Conoco Chemicals' lead limit: 8 hours--50 micrograms per cubic meter Conoco Chemicals' work rules and practices limits your exposure to lead-containing materials to no more than 50 micrograms of lead per cubic meter of air, averaged over an eight-hour period. 48. Photo split/Storage sphere and lead shot That's about equal to the weight of one size-7 lead shot from a shotgun shell if it were mixed in a volume of air equal to that in our VCM storage sphere.

Type/Skin contact regulated If you work more than eight hours a day, your allowed exposure is even lower. For instance, if you work 12 hours, your average exposure limit is no more than 33 micrograms of lead per cubic meter of air. And, even though lead can't be absorbed through the skin, your skin contact with lead materials is strictly controlled by work rules, because after you've worked around lead compounds, you could later transfer small amounts of the powder to your mouth--when eating, smoking or during personal grooming.

Type/Engineering controls are not fool-proof 55. Type/Work rules 56. Build on slide #55/ o breathing protection o personal hygiene Our goal here at the Aberdeen chemical plant is to reduce lead exposure levels through engineering changes and sound work practices. The ventilation systems in the compound area and color weigh room catch dusty materials--including lead--as they are generated. This prevents them from being inhaled and reduces skin contact. The separate vacuum system helps keep these areas clean. Engineering controls, however, are not 100 percent-effective. They could fail to operate properly. Therefore, we've established some work rules to protect your health. The rules are aimed at two things: Breathing protection, and personal hygiene.

Photo/Employee washing hands in middle rest room First, breathing protection. Any person charging blenders at the compound lines, or working in the color weigh room while ingredients are being weighed, will be required to wear a 3-M airhat, for effective breathing protection. In addition, these work areas are marked with signs. Be sure you follow them! In terms of personal hygiene, whenever you are handling lead compounds, you must wear disposable coveralls to keep the lead from contaminating your clothes or skin. And, if your job assignment requires you to come in direct contact with lead-containing materials, you must wash your hands, arms and face and other exposed areas of skin when you've finished. This is most important. 000035*76 SM- Aberdeen Lead Exposure 10 February 1983 Page 14 61. Photo/Removing disposable coveralls 62. Photo/employee vacuuming clothes 63.

Photo/Another employee washing up Take off your disposable coveralls and leave them in the work area before you enter lead-free areas of the plant--especially the break room, rest room and control room areas. You must also vacuum off your clothes thoroughly before leaving the area. Because you might accidentally get lead in your mouth, no food, drinks or tobacco products are allowed in the controlled areas, and no cosmetics can be applied. In fact, these items must not even be carried into these areas, because they could pick up lead compound dust, and you could ingest it later. Leave your food, drinks, tobacco and cosmetics outside the controlled areas. Then, once you leave the area, and before you use them, be sure to wash your hands, arms, face and any area of exposed skin thoroughly, and vacuum your clothes.

Type/Work rules are for everyone When weighing batches of lead materials in the color weigh room, or charging blenders with lead-containing materials, you must follow the prescribed operating procedures to help keep down the dust. Also avoid unnecessary crushing or handling of the empty bags outside the ventilation hood. To minimize your contact with lead-contaminated equipment or materials during maintenance, repairs or similar work, make sure the equipment and work area is first properly cleaned by the operating department. All persons, such as plant visitors, vendors, contractors, or delivery persons, must also follow our work rules regarding lead. SAL 000035473 Aberdeen Lead Exposure 10 February 1983 Page 16 69.

Photo/Air sampling system Now for a word to take home with you. Obviously, the lead materials in the air could settle on your clothing, and could go home with you. That's why we require you to wear disposable coveralls, vacuum off your clothes and wash your face, hands and other exposed skin before leaving the plant. If you do this, you shouldn't have any problems about taking lead dust home. But, it would still be a good idea to change clothes when you get home, and take a shower, too. And put your work clothes and shoes away so they won't be disturbed until they're worn again or washed. And, wash them often. We use a personal air-sampling system on a regular basis to check your exposures to lead in the work areas. Aberdeen Lead Exposure 10 February 1983 Page 17 74. Photo/Employee dosimeter card 75. Photo/Employee filling out card 76. Type/ We'll inform you of any overexposure When you wear one of the monitoring devices, you'll also be given a dosimetry card. When you fill this out at the end of the work shift, be sure to record those times you wore a respirator, and the work you were doing. Also include any unusual events that could have been a cause for overexposure to lead. This kind of information, when cross-checked with the lab results we get back from the air samples, will help us correct overexposure problems as soon as possible. And, of course, if the results indicate you may have been overexposed to lead, we'll let you know as quickly as we can. ooot^ b,*0 Aberdeen Lead Exposure 10 February 1983 Page 18 77. Type/Overexposure? WHY?? 78. Photo/Checking vent hoods 79. Type/Free medical testing 80. Photo/Blood test Whenever any of our tests indicate you may have been overexposed to lead--from whatever source--we'll be checking with you about the possible causes of the overexposure. The object is to isolate the source of lead so we can take steps at once to correct the problem. We also regularly measure air flows through the work area vent hoods. When these flows drop below acceptable levels, the system is thoroughly checked and cleaned out or repaired as needed. To insure that our work practices are effective, and to make sure you don't suffer from the harmful effects of lead, we provide free medical tests twice a year. This is done by blood lead analysis--the only fool-proof way to be sure your exposure is within safe limits. OCOC35A81 SAL Aberdeen Lead Exposure 10 February 1983 Page 19 81. Photo/Employee looking at records 82. Type/Chelation--speeds removal of lead from the blood 83. Type/Should not be used routinely Our lead monitoring and medical records are available for your inspection. Just ask the Safety Department. You will also receive a copy of the results of your physical at the time the doctor examines you. And, we'll provide a copy of your medical records for your doctor if you request it in writing. We recommend that your own personal physician keep accurate and up-to-date records for you on file. Even though testing shows that blood lead levels of our employees are well within acceptable limits, and shouldn't require any medical treatment, we still want to mention chelation. It's a type of medical therapy used to speed up removal of lead from the blood. However, it can be dangerous and should not be used routinely. s^i- CC0C354P2 Aberdeen Contractor Safety January 1983 Page 20 84. Type/Under direction of licensed physician 85. Type/Review 86.

Ask your doctor. Now for a quick review. Remember the hazards of lead exposure: Sufficient quantities can damage your nervous system, kidneys, reproductive organs and blood chemistry. It can even kill you. Lead can be inhaled or taken into the body through the mouth. The form of lead we use in our plant cannot be absorbed through the skin. 00003 sM- Aberdeen Lead Exposure 10 February 1983 Page 21 89. Repeat slide if 57 90. Repeat slide #60 91.

Type/Monitoring and medical testing are for your benefit Wear the proper clothing and breathing protection equipment when charging blenders at the compound lines or working in the color weigh room while batches are being weighed. Always wash your hands, face, arms and other exposed skin, and vacuum your clothing after leaving one of the controlled areas, or after handling lead compounds. Remember, lead can get in your blood from the sandwich you eat with dirty hands, even if you obey all the other work rules. That's the reason no food, drinks, tobacco products or personal grooming aids are allowed in any of the controlled areas. Finally, our monitoring and medical testing programs are for your benefit. Aberdeen Lead Exposure 10 February 1983 Page 22 93. Type/Question and Answer time 94.
