Oregon Occupational Safety and Health Division Oregon Administrative Rules AO 1-2025 Division 2 - (c) The shade must be located as close as practical to the areas where employees are working. - (d) Shade present during meal periods must be large enough to accommodate the number of employees on the meal period that remain onsite. - (e) If trees or other vegetation are used to provide shade, such as in orchards or forests, the thickness and shape of the shaded area must provide sufficient shadow to protect employees. - Exception: When the employer can demonstrate that providing access to shade is not safe or it interferes with the ability of employers and employees to complete the necessary work in a particular situation, for example, during high winds or when an employee is walking through range land, employers must identify and implement alternative cooling measures that provide equivalent protection such as providing cooling vests (either with fans or ice packs), water-dampened cotton clothing, or similar effective measures. The Heat Illness Prevention Plan under section (8) must include the use, care, and maintenance of the alternative cooling methods, in writing. - (4) Drinking water. Ensure that a sufficient supply of drinking water is immediately and readily available to exposed employees at all times, at no cost, when the heat index in the work area equals or exceeds 80 degrees Fahrenheit. - (a) Supplied drinking water must be either cool or cold, see subsection (2)(b). - (b) Supply each employee with enough drinking water to enable them to consume up to 32 ounces per hour. Employers are not required to supply the entire quantity of drinking water needed for all employees on a full shift at the beginning of the shift. Employers may begin the shift with smaller quantities of drinking water when effective procedures are established to replenish the water consumed during the shift. - (c) Employees must have ample opportunity to drink water required under this…

J Division 2 AO 1-2025 Oregon Administrative Rules Oregon Occupational Safety and Health Division - (B) NIOSH work/rest schedule: Implement a written heat illness prevention rest break schedule using the information found in section 3 of Appendix A: Mandatory Information for Heat Illness Prevention based on NIOSH recommendations. - Note: The NIOSH work/rest schedule uses unadjusted ambient temperatures (in degrees Fahrenheit), and employers must follow the instructions underneath Table 3.1 in Appendix A: Mandatory Information for Heat Illness Prevention. Employers must be aware that different work/rest schedules exist for those wearing chemical-resistant suits; see Table 3.2 in Appendix A: Mandatory Information for Heat Illness Prevention. - (C) Simplified heat illness prevention rest break schedule: Implement a written simplified heat illness prevention rest break schedule using Table 2. Table 2 - Minimum simplified rest break schedule: Note: The Table 2 heat illness prevention rest break schedule is only required during the specified heat index. - (f) The heat illness prevention rest breaks under subsection (5)(e) are only required during the specified heat index, and may be provided concurrently with any other meal or rest period required by policy, rule or law -if the timing of the preventative rest break coincides with the otherwise required meal or rest period. However, the heat illness prevention rest break must be calculated using only the time spent in the shade and w hen employees are not performing work other than 'rest' or 'light' work. The requirement for heat illness prevention rest breaks does not prohibit 'rest' or 'light' work -related activities conducted in a temperature-controlled environment, such as paperwork, at the discretion of the employee. - (g) Except when the heat illness prevention rest breaks coincide with the existing unpaid meal break, the heat illness prevention rest break is a work assignment.
