Proctor to Board of Directors J T THORPE COMPANY DATE November 10, 1972 subject Proposed OSHA Compliance Procedure for Thorpe Products Company Asbestos Dust We are setting out below steps that have been taken and proposed methods for future compliance with current OSHA Asbestos-Dust Standards. Standard effective July 7, 1972 The 8 hour time-weighted average airborne concentration of asbestos fibers to which any employee may be exposed shall not exceed five fibers, longer than 5 micrometers, per cubic centimeter of air. METHODS OF COMPLIANCE I. Engineering Controls Our fabrication shop has an effective dust collection system carefully maintained. In addition, we have added booster collectors to saws which cut asbestos containing materials. The warehouse floors are vacuumed daily to remove loose fibers. Rail cars are vacuumed periodically as they are being unloaded. Delivery vans are vacuumed daily. II. Personal Protective Equipment A. Air purifying respirators Approved respirators are provided each warehouse and shop employee. These are carried during working hours. They are worn when the following duties are performed and when Engineer ing Controls are not possible. 1. Unloading or loading rail cars. 2. Unloading or loading delivery vehicles. 3. Repackaging 4. Cutting NOTE ee Hearing of respirators will be required until we have documentary proof of compliance. continued S4 T H O R P t= OFFICE CORRESPONDENCE FROM - DATE TO Page 2 SUBJECT II.

Dust collection Filters are as produced by Millipore Corporation Aerosol Cat. No. MAWP 037A0. An Aerosol Adapter No. XX6200004 is necessary for use with the Micronaire sampler. Personal samples will be taken from those employees exposed to asbestos materials. Sampling frequency will be at least once each six months. B. Environmental monitoring Same as for personal monitoring but sampler will remain station ary at work station for full eight hours. All work stations with asbestos exposure will be monitored at least once each six months. NOTE: Dust'Analysis will be done by J-M Industrial Hygiene Engineering Services Division. IV.

All monitoring records will be maintained for a period of three years. B. Each employee will have access to his personal record upon request. C. Any employee found to be in excess of exposure limits will be notified in writing within 5 days of the finding. Medical Examinations A. Each warehouse and shop employee exposed to asbestos dust will be given a medical examination in accordance with OSHA require ments prior to January 31st, 1973 and annually thereafter. B. New employees will be examined within 30 days of employment. C. A medical examination will be made available to any employee within 30 days of termination. D. Medical records will be maintained for 20 years. E. Access to these records will be available to OSHA, NIOSH and to the employee or former employee. We believe that we have taken steps as required by the law and in some instances beyond those required by the law to insure that our employees have a healthy atmosphere in which to work. We believe that we are in full compliance with the law and have no dust exposures which exceed the standard. We will prove this with monitoring and our first complete analysis will be available prior to January 6th, 1973. continued. 4A I H- <J R P L OFFICE CORRESPONDENCE DATE TO SUBJECT Page 4 The obvious long term solution is to eliminate asbestos fiber containing materials from our warehouses.

C. Shelden, Jr., Director Board of Directors J T Thorpe Company 6833 Kirbyville Street Houston, Texas PROGRESS REPORT ON IMPLEMENTATION OF 1971 FEDERAL OCCUPATIONAL SAFETY & HEALTH ACT At the request of Mr. F. C. Shelden, Jr., a report has been prepared to outline our efforts thus far to comply with the Federal Occupational Safety & Health Act of 1971, and the work remaining to be done in this area. The attached report Is in four parts. The first outlines In general the major areas of impact of the law on J T Thorpe Company's contract operations. This is followed by our overall plan for Implementation of the law and the steps we have taken thus far. Finally, we have outlined the work remaining to be done with particular emphasis of the year 1973. Please advise if you have any specific questions on the foregoing, or wish to have any additional specific information. PROGRESS REPORT IMPLEMENTATION-OF 1971 FEDERAL OCCUPATIONAL SAFETY & HEALTH AG IN J T THORPE COMPANY CONTRACT OPERATIONS NOVEMBER, 1972 I. Major Areas of Impact Physical Facilities Jobsite Practices Field Labor Productivity Contract Profitability 4 Estimating Procedures Type of Work 4 Materials Used As you are aware, OSHA announced two programs at the outset, a target industries program and a target health hazards program. The target industries program was to concern itself with the five top injury prone industries; longshoring, roofing and sheetmetal, meat and wood products, lumber and wood products, and miscellaneous transportation equipment. We, of course, perform sheetmetal work although probably not in the sense that OSHA was zeroing in on. Their target health hazards program included lead, carbon monoxide, silica, asbestos and cotton dust. We, of course, are very much involved in the asbestos problem as has previously been outlined to you Mr. M. P. Proctor in his compliance procedures for Thorpe Products Company. In addition, certain of our operations put us In direct contact with the silica health hazard. In the very near future, we will be developing a detailed program to combat these latter two hazards in our field operations on a broad scale. We also anticipate the construction industry will become one of OSHA'S prime targets In the very near future. The potential impact of the law is so great, it is difficult or nearly impossible to instantaneously implement all aspects of the law. Accordingly, our approach has been to make a beginning on a broad basis, correct imnediate and obvious violations of the Act, undertake an educational program for our employees, and develop a plan for the longrange. Mentioned above were five areas of our activities where we anticipate significant change or effects due to the new Law. Physical facilities are the most obvious and the most easily inspected, and certain efforts and expenditures have been and will be undertaken to bring our warehouses and offices into compliance with the Law. As time progresses, and the Act becomes fully implemented in the construction industry, certain practices that have prevailed in the past on construction jobs will no longer be permitted, as indeed some of our past practices have already been changed or prohibited. Hand-in-hand with this implementation of the Law, will be a potential affect on field labor productivity. In some Instances, productivity may actually increase due to im proved working conditions. However, the effort and expense required to bring about this condition may adversely affect contract profit ability. To account for this eventuality, we will need to maintain a close watch over contract costs and possibly modify our estimating -2- Si Procedures to account for this impact. You are certainly aware of the asbestos problem, and thus the materials we use in our work will be affected, and we may even need to reconsider the types of work we are now engaged in. On the brighter side of this picture, we feel companies such as Thorpe that are intending fully to comply with the law and are cognizant of its requirements, will have their services in greater demand in the coming years. II. Overall Plan For Implementation Of The Law In Thorpe Contract % Operations. Our plan to implement compliance can be simply stated: Comply with the Law in all aspects. However, as mentioned previously, the . scope of the law is so broad and its effects so far reaching, that it is. virtually impossible for a company of our size to effect overnight total compliance. Accordingly, we have pursued a rather informal plan thus far which has consisted of taking the immediate necessary steps to bring about compliance in our operations, partic ularly in areas that have been well publicized and are the more obvious items. For the longer range, we are beginning to develop specific policies in certain areas such as environmental testing, personnel training, and facilities modifications. Also required will be reminders of the importance of certain items which need to be followed on a day-to-day basis, and tend to be forgotten with the passage gf time. As we continue to approach complete compliance -3- f 44 with the existing law, we will also need to implement the new standards as promulgated by the Federal Government and State Agencies. One of the most publicized problems with the new law has been the difficulty of small companies, and companies the size of Thorpe to familiarize themselves with the many facets of the law arid bring about compliance. We feel this is a very real problem and have exerted considerable effort toward this end. Where the % real problem exists in our organization to a greater degree is in our branch office locations and subsidiary company locations. To combat this problem, we will endeavor to keep the supervisory personnel in those locations abreast of new developments and policies as they are available. III. Actions Taken To Date To Bring About Compliance With The Law This section of our report will consist of a listing of most of the more significant things done thus far, with a following elaboration on certain Items and examples. 1.

For structural beams and angles, trowel the cement mixture thoroughly into the rib lath for good anchorage, and build the cement up to a full _1-3A" coverage over the rib lath as the work progresses to avoid laminations. Use a screed so that the minimum thickness is obtained, trowel the surfaces and chamfer the corners uniformly. U.O.P SPEC. 338 PAGE 4 OF 6 2. For structural columns, apply a first coat approximately 3/b" thick, troweling the cement thoroughly into the rib lath for good anchorage. Scratch the entire surface and allow to set for 8 hours or more. Support and hold the comer beads away from the first coat by gobs of cement spaced about 2' centers and tie them securely as indicated in Fig, 338-1 so as to obtain a 1-3A" minimum coverage of the lath. Fill the space between the wings with cement by hand, and trowel the final coat flush with the beads as the filling progresses.
