             A.           GENERAL

             Heat stress generally describes the effect of heat, from any source, on the organs of the body and the
             person as a whole. The stresses of heat on the body manifest themselves in five (5) common ailments:
             heat exhaustion, heat cramps, heat stroke, heat syncope, and heat rash.

             Contractor shall develop a heat stress plan to ensure employees are protected against heat stress.
             Contractor shall submit the plan to Owner for review.

             B.           RESPONSIBILITIES

                          When heat levels become higher than 95F (35C) for whatever reason (natural weather
                          conditions or mechanical heat sources), the Project/Site Manager should instruct his
                          Project/Safety Representative to develop a heat stress management plan for the project/site.

                          The plan should contain the following data:

                               temperatures, expected to be found in the work place, that are based upon environmental
                                factors such as air temperature, relative humidity, air velocity, and thermal radiation;

                               in the basis of temperatures measured, a ratio of work time versus rest periods, with work
                                periods decreasing while rest periods increase as temperature rises;

                               a medical monitoring program for those people exposed to heat stress and those highly
                                susceptible to heat stress (the obese, unacclimatized workers, workers with cardiocirculatory
                                diseases, and employees who may be taking medications or using alcohol heavily);

                               the plan should include a cooler-than-ambient temperature rest location and delivery of iced
                                drinking water;

                               an emergency plan for handling heat stroke and severe heat exhaustion;

                               a plan to engineer out the sources of heat by shielding, insulation, or mechanical methods of
                                reducing heat or increasing air velocity;

                               a training plan to include dietary needs, water consumption, and avoidance of alcohol.
