Note: Using same question numbers as in the question asked for easier identification.
42. True. A site map indicates topographic features, drainage, location of buildings, pond, tanks and pits, wind direction. It is useful for assigning personnel, planning activities, identifying access routes, evacuation routes and site that require use of special Personal Protective Equipment.
43. False. Risk depends on the toxicity of chemicals (i,e., hazard) and on the time duration that the chemical is present in the medium and how much contact the receiver has with the chemical (i,e., exposure of chemical). Hence Risk=Hazard x Exposure.
44. False. Atmospheric testing should be done to ensure supply of adequate oxygen before the permit of entrant.
45. True. Air Purifying respirators can be used if concentration of oxygen is atleast 19.5% as this is the minimum oxgyen required to sustain life and it cannot be used in oxygen deficient atmosphere.
46. True. PPE clothing and equipment should be of safe design so as to provide maximum protection. As PPE eqipments are available in different shapes and sizes, care should be taken to reduce the number of equipments.
47.False. Penetration is the movement of chemical through zippers, seems and punctures of protective clothing. Permeation occurs through the material rather than the opening in the material.
48. False. All employees who work in hazardous sites undergo periodic medical examination as they exposed to toxic chemicals and radiations. A medical program is designed to monitor the worker's health prior to employment and during the working course.
49. True. Level B is selected when a higher level of respiratory protection and a lesser level of skin and eye protection is required.
50. True. The ACGIH has indicated several BEI's for end of shift monitoring.
