These records must also include information on the background noise level of the audiometric test booth. BL Companies will maintain noise exposure measurements for at least two (2) years and audiometric test records for the duration of the affected Employee’s employment. BL Companies will provide access to these records to Employees upon request. 7.4 Heat Stress Purpose Fieldwork conducted by the Company can expose Employees to heat elements. Care must be taken to assure that weather conditions do not compromise health or safety. There are a number of steps that can be taken, either alone or in combination with others, to reduce and control the hazards of heat stress in the workplace. These guidelines are designed to aid in that task.

Scope This Section applies to all field operations and all Employees engaged in such field operations. Policy BL Companies recognizes that work must be performed in various weather conditions, including warm climates. In order to minimize heat related illnesses and injuries, site supervisors will be made aware of the symptoms of heat stress and the environmental conditions that lead to heat related illnesses and/or injuries, and the steps necessary to prevent their occurrence. Heat Stress: Causes, Symptoms and Prevention Each person involved in outside and inside work has the potential to incur heat-related disorders. The most common and easiest heat disorder to incur is heat stress, which could lead to heat stroke and even death. The following precautions should be taken by the Employee to prevent heat stress: · Wear lightly colored clothing. · Allow for acclimatization to hot environment before any strenuous work begins. · Drink plenty of fluids (not alcoholic or caffeinated) prior to and during working hours. · Take frequent breaks when working in extremely heated conditions. · Work in shaded areas whenever possible. · Have access to shaded or air conditioned break areas or, at a minimum, an air conditioned vehicle. Keeping body fluids at normal levels is the best defense from heat stress. It may be necessary to drink more than 1.5 gallons a day to maintain body weight. An Employee should not lose more than 1.5% of total body weight per workday.
