2. Heat Illness Prevention Plan <br /> 2.1 Purpose <br /> 2.1.1 The Department believes that it is the best interest of employees of Public Works while <br /> working to adhere to safety practices related to the reduction of risk of Heat Illness. <br /> 2.1.2 All Divisions with workers whose normal job tasks occur outside of office or building <br /> environments are required to follow these procedures. Those Divisions with workers in <br /> buildings that require work in over 802 F are also advised to comply with these <br /> procedures. <br /> These procedures are implemented whenever the temperature is expected to be <br /> 802 F or above as indicated by the National Weather Service forecast <br /> (http://www.nws.noaa.gov) as of 5 PM the previous day for San Joaquin County. <br /> Each Division is expected to check the weather forecast the day before in order to <br /> ensure that crews and employees are properly prepared and forewarned to <br /> implement these procedures. An alternative is to, in the summer months assume <br /> all days will be at or above 802 F and implement procedures daily. Additional <br /> measures must be implemented when temperature equals or exceeds 959 F. <br /> These additional measures include: effective communication by voice; observation <br /> or electronic means (i.e., cell phones or portable two-way radios) must be ensured. <br /> Any requirements or provisions listed in this program apply to all employees of <br /> Public Works and those Alternative Work Program participants who are working on <br /> projects for the Department. <br /> 2.2 Definitions <br /> "Acclimatization" means temporary adaptation of the body to work in the heat <br /> that occurs gradually when a person is exposed to it. Acclimatization peaks in most <br /> people within four to fourteen days of regular work for at least two hours per day <br /> in the heat. <br /> "Heat exhaustion" is a heat-related illness that can occur after you've been <br /> exposed to high temperatures, and it often is accompanied by dehydration. <br /> There are two types of heat exhaustion: <br /> -Water depletion. Signs include excessive thirst, weakness, headache,and loss of <br /> consciousness. <br /> San Joaquin County <br /> Department of Public Works <br /> County of San Joaquin Dept of Public Works IIPP Rev 2020-01-31.docx P a g e 148 <br />
