This MARADMIN provides updated interim guidance for commanders  (CDRs) and officers-in-charge (OICs) on planning and executing heat and cold stress injury prevention measures.  This guidance remains in effect until incorporated into reference (a) or until superseded. CDRS and OICs will apply risk management principles from reference (b) to implement injury prevention measures for all  operational and training activities, in accordance With references (c) through (e). 2.  Action 2.a.  CDRs and OICs 2.a.(1)  Implement the requirements of references (c) through (e) to  reduce unnecessary risk.  Ensure all potentially exposed personnel  receive training on the causes, prevention, and treatment of heat  and cold stress injuries.  Training shall include the wet-bulb globe  temperature (WBGT) index, work/rest cycles, flag warning systems  and wind chill index.  Medical department personnel are available  to assist with training.   Conduct refresher training at the  discretion of the CDR/OIC and prior to exposure to hot or cold environments.  Document training on attendance rosters. Local policies shall not be less stringent than this guidance.  2.a.(2)  Develop standard operating procedures (SOPs) for training  and operations in hot and cold weather environments, including WBGT  meter operations and maintenance per the manufacturer’s guidance. 2.a.(3)  Take WBGT readings in immediate areas of operations and  communicate WBGT index readings and flag conditions to affected  personnel. 2.a.(4)  Prior to training and operations, ensure personnel are trained, acclimatized and equipped for hot or cold weather  conditions.   2.a.(4)(a)  Designate a sufficient number of trained personnel to monitor training activities, assist stragglers, and transport heat or cold stress casualties in properly equipped vehicles. 2.a.(4)(b)  Notify the supporting military treatment facility (MTF) of the risk assessment and include the time and location of training or operations. 2.a.(4)(c)  Ensure medical department personnel assigned to Marine Corps units can respond rapidly to a heat or cold stress injuries  and provide immediate intervention, including recognition, cooling  or warming, and transport to nearest MTF.   2.a.(4)(d)  Ensure personnel receive adequate fluid replacement,  rest periods and water breaks during hot or cold weather training.  Apply training guidelines in references (c) through (e).  Identify  personnel with risk factors, including prior heat or cold stress  symptoms or use of medications or dietary/fitness supplements.   Ensure those individuals are evaluated and cleared by medical  provider, and monitored by supervisors and buddies for heat or cold stress symptoms. 2.a.(4)(e)  Personnel exposed to excessive heat stress may require  evaluation by a qualified health care provider to determine the  presence or absence of a heat-related injury.  If a heat-related injury is identified, the health care provider shall notify the unit safety representative or other designated command representative for entry into the Risk Management Information (RMI) system. 2.a.(4)(f) All heat or cold injuries will be reported via RMI per reference (b), and through the disease report system internet per  reference (g).  2.b.  Officers, staff noncommissioned officers, noncommissioned  officers and other supervisors shall ensure Marines, Sailors, and  civilian personnel are familiar with heat and cold stress injury  prevention procedures.  Emphasize buddy aid-if an individual  appears ill or otherwise unfit to participate, ensure they report  to medical department personnel for assessment. 2.c.  Installation, base and station commanders 2.c.(1) Operate and maintain the WBGT meter per the manufacturer’s  guidance.  2.c.(2) Take WBGT readings in operational areas with potential heat stress risk and display WBGT flags in accordance with references (c) through (e).   2.c.(3) Communicate WBGT index readings, flag conditions, and wind  chill indexes to all tenant commands. 2.C.(4) Assist units in monitoring heat and cold stress conditions  and provide WBGT loaner equipment as required.  Ensure SOPs exist for the operation and maintenance of organic and loaner WBGT meters. 3.  Release authorized by Lieutenant General, Paul J. Rock, Jr., Director, Marine Corps Staff.//
