training company (BCT, OSUT, and AIT) and will be placed in use when the ambient temperature exceeds 75º and
monitored IAW TR 350-29. Cadre members will carry the pocket-sized GTA 07(GTA) 05-08-12 (Individual Safety
Card) during training, or another suitable locally produced GTA.

(3) Publish a specific SOP on training activities that may or may not be conducted during the various WBGT
indexes/wind chill factors. Decision to accept risk is made IAW TR 385-2; paragraph 1-5d(4). Refer to TR 350-29,
appendix B, for the heat casualty risk factor matrix. The SOP should include the statement that during cold weather,
use of nonstandard portable space heaters is prohibited in field training and operations.

(4) In addition to risk factors found in TR 350-29, donating blood and recent, rapid weight loss due to extreme
measures will increase the risk of a heat illness.
>
>
(5) If the Soldiers have been subjected to heat category (CAT) IV and/or CAT V conditions for two to three
consecutive days, then cumulative heat stress increases their chance for a heat illness on the subsequent day. Riskcontrolling measures include; monitoring living area temperatures of 74 degrees +/- 2 as outlined in AR 420-1;
decreasing the distance and/or pace of unit runs; and changing the training schedule if strenuous events are scheduled,
especially if they are scheduled to occur outdoors in category CAT IV or V conditions.

(6) For Soldiers who are at increased risk for heat illness, pre- and post-activity weighing is an excellent tool for
monitoring their hydration level and managing their risk. Weigh Soldiers the same time each day, after using the
bathroom, before showering, and in underwear. Any weight lost in 24 hours represents loss of water. If weight has
been lost, have the Soldier drink water or an electrolyte drink at the rate of one pint of water per pound, not to exceed
hydration guidelines. If weight has been gained, have the Soldier eat a salty snack, and do not require him or her to
drink more water. If feasible and if sufficient numbers of scales are available, weigh all Soldiers during CAT IV and
V conditions.

(7) For treatment of suspected heat casualty, the use of iced sheets is mandatory. Although guidance from TR
350-29 states that ice sheets should be applied anytime the Soldier has a change in mental status, err of the side of
caution and always apply ice sheets to Soldiers showing any signs of environmental heat overexposure. Any change to
this regulation needs prior approval from DCG IMT. The use of bed sheets cooled with ice water has been proven to
significantly improve the recovery and outcome of persons suffering from heat stroke. Insulated ice chests can be
maintained at training sites by DSs/CLS; carried on ambulances; and/or maintained at troop medical clinics. Prepare
and apply iced sheets as follows:
>
>
(a) Soak normal bed sheets in insulated ice chests full of iced water. The sheets can be kept in resealable
plastic bags ready for use, or kept immersed in the water. Commanders should plan on a minimum of eight sheets per
company.
>
> (b)
Remove Soldier's outer clothing, down to underwear.

>
(c) Cover as much of the exposed skin as possible, and the top of the head, with the ice
sheets.
