Heat Index Action Levels (Contact Project Manager & Notify that Actions Levels have been triggered. Below are recommended additional controls. Each level is additive. If Heat Index indicates "CAUTION" 80 - 89 F.(26 - 32 C). Implement one or more of the following: Provide hydration, schedule breaks, wear lightweight clothing, shaded break areas If Heat Index indicates "EXTREME CAUTION" 90 - 97 F (32 - 39 C). Implement all the above and add one or more of the following: Provide light duty PPE, cooled break areas, shaded work areas. NOTE: "Light Duty PPE" includes items such as hard hat sun shades, sun hats, and dry or wet evaporative cooling vests, microfiber towels, scarves, headbands, hard hat neck shades, hard hat suspension inserts and sweatbands. If Heat index indicates "DANGER" 98 - 107 F (39 - 43 C). Add one or more of the following: Provide cooled work areas, modify work schedule, provide heavy duty PPE, vital sign monitoring & Stop Work NOTE: "Heavy Duty PPE" includes phase -change cooling vests, gel pack and ice pack equipped cooling vests. Ice pack vests are generally offer the coldest option and should not be worn directly against the skin. If Heat index indicates "EXTREME DANGER" >108 F (44 + C). or greater Stop Work until conditions change or hazards are effectively controled. Procedures for High Heat Conditions and Heat Waves These procedures are additional preventative measures to be implemented when the temperature is > 95 deg F (35 C). The SSO or designee is responsible for ensuring effective observation and monitoring of employees during periods of high heat by implementing one or more of the following procedures: 1. SSO or designee will supervise 20 or fewer employees. 2. The "Buddy System" is mandatory. Conduct routine checks for early signs of Heat Illness. Set and verify routine consumption of water & sports drinks in a 3:1 ratio. 3. Maintain regular communication between Project Manager or SSO / designee and field staff (e.g. via mobile phone, radio or another effective means) for observation of early signs of heat illness. 4. Designate one or more employees as authorized to contact emergency medical services and communicating that if no designate is identified and the SSO is unavailable that any employee can call for emergency medical assistance. 5. Modify work schedule to avoid hottest parts of the day (DEFINE THIS TIME PERIOD AND IF ABLE TO, START EARLIER OR WORK LATER). Tailgate Safety Meetings will include a review the high heat procedures, encourage employees to drink plenty of water, and remind employees of the importance to take a preventative or recovery cool -down rest when necessary. The "Buddy System" must be implemented. Particular attention needs to be paid to new employees or employees who have yet to acclimate to high heat conditions. Additionally, frequent communication will be maintained with employees working by themselves (via cell phone or two-way radio), to be on the lookout for possible symptoms of heat illness. Employees will be observed for alertness and signs and symptoms of heat illness at regular intervals to be documented in the field book or field log. AdElhWhen the SSO is not available, an alternate responsible person must be assigned to look for signs and symptoms of heat illness. Such a designated observer will be trained Ml and know what steps to take if heat illness occurs. "Heat Wave" Procedures A "heat wave" as defined by the National Oceanic and Atmospheric Administration (NOAH), is a period of abnormally and uncomfortably hot and unusually humid weather." Typically, a heat wave lasts 2 or more days. A "Heat Wave" as defined for the purposes of this Standard is when temperatures are sustained above 80 deg F (26 C). During a heat wave or if site conditions indicate the potential for "Extreme Caution", "Danger" or "Extreme Danger" per the NOAA Heat Index Table the following steps will be taken: Work schedules will be modified to protect workers from heat illnesses. The SSO or designee in coordination with the project team, will use their Stop Work Authority and evaluate the following actions and document the action in the daily field log 1 Modify work hours. 2 Reschedule or suspend work or specific tasks that are strenuous. 3 Cease work for the day. If schedule modifications are not possible, the Heat Illness Prevention Plan will be reviewed before work resumes. At a minimum, procedures for heat illness prevention, the provisions of the high heat procedures, the weather forecast and emergency response protocols will be reviewed. Employees will be provided with additional water and rest breaks and will be observed more frequently. During work activities and rest breaks, employees will be observed for signs and symptoms of heat illness. All employees will maintain frequent communication with the SSO or designee, who will be monitoring workers for possible symptoms of heat illness. In the event of large project sites where the SSO may be unable to be near the workers (to directly observe or communicate with them), then communication via a cell phone or radio may be used for this purpose provided reception in the area is reliable. Procedure for Emergency Response Emergency procedures include recognizing the symptoms of heat related illness. A critical step also involves ensuring that effective communication is established either through voice, direct observation or electronic means such as via mobile phones or 2 -way radios. In an emergency situation it is critical that employees understand the process and contact information for requesting emergency medical support. The reception coverage for the site must be evaluated and understood to ensure adequate communication is in place across the project site 1. The SSO or designee is responsible for implementing the following procedures for emergency response. These procedures include, but are not limited to, the following: 2. Prior to assigning staff to a particular work site, during the Tailgate H&S Tailgate Safety Meeting all site workers will review a map of the Site along with clear and precise directions (such as streets or road names, distinguishing features, and distances to major roads), to avoid a delay of emergency medical services. 3. Prior to assigning staff to a particular work site, efforts will be made to ensure that a qualified and appropriately trained and equipped person is available at the site to render first aid, if necessary. • 4. Prior to the start of the morning Tailgate Safety Meeting, a determination will be made of whether or not a language barrier is present at the site, and steps will be taken (such as assigning the responsibility to call emergency medical services to the SSO or an English speaking worker) to ensure that emergency medical services can be immediately called in the event of an emergency in accordance with the HASP.
