Work/rest schedules are often based on 1-hour cycles and might call for a rest period of 15 minutes every hour during hot weather, but 45 minutes per hour when temperature and humidity are extreme. Observe your employees, note their movements, posture, speed, effort, weight of materials they ... -Employee is resting as part of a work/rest schedule or is awaiting instructions etc. The information contained in this article is intended for general information purposes only and is based on information available as of the initial date of publication. Use reflective or heat-absorbing shielding or barriers. To prevent heat-related illnesses, it’s important to establish an effective work/rest schedule according to the environment and heat employees experience in the workplace. When an air conditioned space is not available, choose or create rest areas with as many of the following beneficial characteristics as possible: Rather than being exposed to heat for extended periods of time during the course of a job, workers should, wherever possible, be permitted to distribute the workload evenly over the day and incorporate work/rest cycles. -- During the summer, the bioenvironmental engineering flight performs wet bulb globe temperature readings that determine a heat category and work/rest cycles. Since these should not be the solution to the problem here are some solutions you may think are appropriate for your type of work…. Heat Category WBGT Index (ºF) Easy Work Walking on hard surface, 2.5 mph, <30 lb. The WBGT is often confused with the heat index, which is a measurement of ambient temperature, including the effect of relative humidity. Factors such as lack of acclimitization, poor fitness, and cumulative inadequate hydration and may increase the risk of heat-related illness and should be taken into account when using the schedules in Figure 1. The human body gains and loses heat in two ways: body heat – the internal heat generated by metabolic processes Rotate workers in extreme heat if possible. the work that their workers are doing, and allocate manpower and resources appropriately, to reduce the risk of heat stress. The plan should ensure that medical services are available if needed. of work in the specified heat category. It defines the project goal, scope, resources needed, costs, etc. Individual requirements may vary greatly. Consider rescheduling activities for a time when the risk of heat illness is lower. If your body heats up faster than it can cool itself, you experience heat stress. Where surfaces are not warm from earlier sun (e.g., north-facing wall). Contact OSHA's On-site Consultation Program for assistance in developing your heat-related illness preventions plan and work/rest schedules that appropriate for your worksite. activity, work in the direct sun, or work with other sources of radiant heat, additional precautions are necessary to protect employees from heat-related illness. Develop a heat stress program incorporating the following: Training program about recognizing and reducing heat illness; Screening program to identify heat-related health conditions; Employees can still work during “rest" periods, so long as they are not performing heavy labor or standing in the sun. This work/rest schedule method is published as: Heat Stress and Strain, in TLVs and BEIs, American Conference of Industrial Hygienists, Cincinnati, OH. During the rest periods, workers may continue to perform mild or light work, such as completing paperwork, sorting small parts, attending a meeting, or receiving training (e.g., instructions for upcoming work, or a tailgate safety talk). Often it requires the assistance of a trained safety and health profession.
