PROLONGED EXPOBURRS TO CONCENTRATIONS ABOVE THE LIMITS NOTED MAY ArPhOT THB CBMTRAL NMAVbUl §YOTIM O CAROIGVASCVL.AR SYSTEM, A49PIBATORY IVITBM* BIYEB, BKIH* KIDNEYN, BONPR KUD BONE MARROW. IRNONARCH MAO MOWN THAT BENZENE IS A CARCINC .EN . IMMEDIATE SYMPTOMS OF OVER-EXPOSURE INCLUDE: EYE IRRITATION, NOSE IRRITATION, THROAT IRRITATION, HEADACHE, NAUSEA, DIZZINESS, DROWSINESS, WEAKNESS, CONFUSION, EUPHORIA, EXCITEMENT, STAGGERED GAIT, ABDOMINAL PAIN, RESPIRATORY DIFFICULTIES, MUSCLE FATIGUE, AND COMA. IN ORDER TO PROTECT AGAINST OVER-EXPOSURE TO THESE COMPOUNDS, THE AMBIENT AIR WILL BE MONITORED WITH A "LOWER EXPLOSION LIMIT/ OXYGEN CONTENT" METER AND/OR A HANDHELD PHOTO IONIZING DETECTOR (PID) . AS SOON AS VAPOR CONCENTRATIONS APPROACH 75% OF THE EXPOSURE LIMIT VALUE, WORK STILL CEASE UNTIL ALL ONSITE PERSONNEL HAVE DONNED PROTECTIVE CLOTHING AND SUITABLE RESPIRATORY DEVICES. DUE TO THE INHERENT PHYSICAL DANGER OF WORKING IN THE VICINITY OF MOVING HEAVY MACHINERY, ALL PERSONNEL WILL WEAR HARDHATS AND STEELTOED FOOTWARE AT ALL TIMES. PERSONNEL EXPOSURES TO EXCESSIVE JOB--RELATED HAZARDS ARE EXPECTED 70 BE MINIMAL USING THESE SAFEGUARDS. IT SHOULD BE NOTED THAT SUMMERTIME HEAT MAY INITIATE WEATHER • STRESS-RELATED PROBLEMS AND DECREASE PRODUCTIVITY ON THE JOB SITE. RISK ASSESSMENT SUMMARY THE PRIMARY SAFETY GOAL DURING THE CONTAMINATION ANALYSIS IS TO PROTECT THE SAMPLING TEAM AND SUPPORT STAFF WHILE THEY ACQUIRE REPRESENTATIVE SAMPLES. IF PROPER LEL VALUES (AS ESTABLISHED BY THE FIRE MARSHAL) ARE MAINTAINED, THEN THE RISK OF EXPLOSION AND RESULTING FIRE WILL BE MINIMAL. DUE TO THE UNCONFINED NATURE OF THE PROJECT SITE, TOXIC VAPORS RELEASED DURING TANK REMOVAL OPERATIONS WILL BE SUFFICIENTLY DILUTE') BY AMBIENT AIR SO THAT THE SURROUNDING COMMUNITY WILL BE EXPOSED TO NEGLIGIBLE RISK. IN ORDER TO ASSURE THAT VAPOR DISPERSAL IS ADEQUATE, A HANDHE__D PHOTO IONIZING DETECTOR (PID) WILL BE USED PERIODICALLY TO MONITOR VAPOR CONCENTRATIONS. W:YILE THE PROPRIETORY BUSINESS WILL NOT BE IN OPERATION DURING OUR INVESTIGATIONS, IT IS OUR EXPERIENCE THAT POTENTIAL CUSTOMERS WILL ATTEMPT TO GAIN ENTRY ONTO THE SITE. FOR THIS REASON BARRIERS OF VARIOUS TYPES WILL ENCOMPASS THE WORK AREA. EXPOSURE MONITORING PLAN ENVIRONMENTAL EXPOSURE WILL BE MONITORED PERIODICALLY USING A HANDHELD PID. DUE TO THE RELATIVELY SHORT DURATION OF THE SAMPLING ACTIVITIES, PERSONNEL EXPOSURE MONITORING ( IN ADDITION TO THE REQUIRED ANNUAL CHECK-UP) WILL, NOT BE CONDUCTED. • page 3
