Safety and Health Plan Sandhu Property Tracy, California October 22, 2021 Terracon Project No. NA217074 22 17.1 Evacuation and Shutdown Procedures The SSO will establish and notify site personnel of emergency "rally" points. In the event of a site emergency, personnel will immediately exit the site and assemble at the designated rally point. Evacuation routes will be dependent on site topography and wind conditions. The routes will be selected and presented by the SSO daily prior to site activity. If emergency evacuation becomes necessary, the SSO will sound the emergency alarm (e.g. support vehicle horn or compressed air horn). Personnel will safely shutdown all electrical and mechanical equipment and quickly proceed to closest designated rally point. The SSO will then account for each crew member on site. In the event that a Terracon employee does not report to the designated rally point within 5 minutes of the evacuation alarm, the SSO will perform an immediate assessment of site conditions. If site conditions do not pose an immediate hazard to life or health, the SSO will initiate search and rescue efforts utilizing two crew members attired in appropriate personal protective equipment. 17.2 THERMAL STRESS Heat Stress Whenever ambient temperature exceeds 70 degrees F and personal protective equipment requirements are Level D or Level D modified, the following heat stress monitoring and preventive measures will be implemented: •Mobilize at least one gallon of water for each field employee during each day of site activity. •Periodically observe personnel for signs of heat stress (excessive perspiration, flushed skin, nausea, etc.). •Move affected workers out of contaminant zones, •Loosen protective clothing and permit them to rest •Have conscious, affected personnel drink at least one 8 oz. glass of cool water. •Check pulse; personnel should not return to work until pulse rate is less than 90 beats/min. Heat Stress in Level C/Level B PPE In addition to the above precautions, the following procedures will be implemented whenever the ambient temperature exceeds 70o F and personal protective equipment requirements are Level C or above. Ambient temperature will be measured with a dry bulb thermometer and percent cloud cover will be estimated: 1.0 = No Clouds
