Code 7542 applies to employers engaged in meter reading operations for utility companies.  Meter readers normally work outside and drive from location to location in order to read customers’ utility meters.  Some utility companies now have their employees utilizing scanners to read the meters instead of physically reading the figures from the meters.  The figures obtained from the reading report the amount of gas, water or electricity a customer has used.  The customers will then be appropriately billed for the usage.  Meter readers are not exposed to any other operative hazards of the utility company and do not engage in repairing or installing utility meters.
