Arcadis Heat Illness Prevention Plan (HIPP) <br /> HASP Supplement <br /> Access to Shade Continued <br /> 5. In situations where it is not safe or feasible to provide shade, the SSO will document in the HASP <br /> Supplement the unsafe or unfeasible conditions, and include the steps taken to provide alternative <br /> cooling measures equivalent to shade. <br /> Unsafe/unfeasible conditions: <br /> Alternative Cooling Measures Implemented: <br /> Provide vehicles with working air conditioner to all employees for rest breaks / <br /> X recovery breaks / meal breaks. <br /> Provide temporary or mobile shade structure(s) that are either ventilated or <br /> open to air movement (Secure against wind.) <br /> Provide a building / permanent structure(s) in close proximity to the work area <br /> with a cooling environment via mechanical ventilation or open to air movement <br /> which will be used for shade. (Job trailer, pavilion, manufacturing building, etc.) <br /> Other: <br /> Monitoring of Weather and Heat Index Table <br /> 1. The SSO or designee must check the extended weather forecast in advance of the upcoming <br /> work on a weekly basis. Work schedules will be adjusted in advance, taking into consideration <br /> whether high temperatures or a heat wave is expected. <br /> Accepted weather forecasting resources include webpages "NOAA.gov" or"weather.com" or see the <br /> NIOSH Heat Tool (formerly the OSHA Heat Tool app) <br /> https://www.cdc.gov/niosh/topics/heatstress/heatapp.htmi <br /> 2. Before work starts for the day or shift, the SSO will review the forecasted temperature and <br /> humidity for the (exterior)work site and compare conditions against the National Weather Service <br /> Heat Index (below)to evaluate the risk level for heat illness. Determination will be made of whether <br /> or not workers will be exposed to a combination of temperature and humidity characterized as <br /> "Caution", "Extreme Caution", "Danger"or"Extreme Danger"for heat illnesses. <br /> NOTE: It is important to know the temperature at which these warnings occur. When working <br /> outdoors see the Heat Index Table in this supplement for Action Level specific instructions for <br /> hazard controls. <br /> 3. Where state regulations indicate a thermometer or similar on-site monitoring device will be used <br /> at the job site to monitor for sudden increases in temperature. The SSO will be responsible for <br /> obtaining a thermometer/weather station prior to the start of work and make it readily visible/ <br /> accessible where it can easily be monitored throughout the course of the day. <br /> NOTE: If the temperature is > 80°F (26 C) shade structures will be opened and made available <br /> to workers. If temperature is > 95° F (35 C) additional preventive measures will be implemented. <br /> Rev 8 13 June 2019 <br />
