DATE OCTOBER 23, 1970 from HOUSTON REFINERY MANAGER
subject HEALTH AND SAFETY
Further to the General Manager Refineries letter on Health and Safety dated October 6, 1970, and the subsequent reference letter dated October 8, 1970, Attachment No. 1 outlines the references used for threshold limit values and safeguards for hazardous materials, etc.
In addition to using explosion meters and oxygen analyzers, we utilize Mine Safety Appliance and Scott, Drager detector tubes for determining the concentrations of hazardous materials throughout our operations.
In the design of process equipment, health and safety is of primary consideration. Engineering designs include safeguards for the control of noise, dispersal and/or recovery of released toxic materials, personnel safety equipment, fire protection, etc. The Refinery Safety Department and the Engineering Services Department inspectors further enhance safety on the job by constantly inspecting operating equipment and assuring safe work procedures through our work permit system.
Formal safety training is carried out by first line supervisors under the direction of operating department managers and the Safety Department at weekly and monthly safety meetings. Operator training for emergency operating procedures is given special emphasis.
Hourly employees are examined every three years by our company physician. If known physical deficiencies exist, employees are examined on a three to six month cycle, depending on their medical history. Those employees working in radiation areas are given an annual medical check including blood test.
The Houston Refinery has a plant hospital staffed 24-hours per day by registered nurses for all first aid cases. When any injury occurs requiring the attention of a physician, an ambulance is maintained for such emergencies. In the event of a disaster, the Houston Ship Channel area has a mutual aid organization whereby additional medical personnel and emergency equipment is available upon request.
Breathing air from the plant air system is not used for respiratory protection due to the possibility of contamination. The Safety Department tests the breathing air cylinders used for respiratory protection in order to rule out the possibility of contamination by our suppliers. An air compressor provided with a remote air intake manifold is used for tank maintenance requiring respiratory protection.

GENERAL MANAGER REFINERIES
In those areas where nitrogen or other inerts are present, appropriate signs and guards are placed to prevent inadvertent entry. Further, a Fire and Safety Permit is required before entering tanks, vessels, columns, etc., as outlined in our Refinery Safety Manual.
In Attachment No. 2, hazardous materials shipped or used in operations are listed in the manner requested in your memorandum. No attempt has been made to list the numerous chemicals used by professional employees in our Refinery and Research Laboratories.
At this time, we do not know of any areas requiring outside research except possibly audiometric testing of employees' hearing and further research for particulate matter. Please let us know if additional information is required.
