The latest reading for the CFB Shilo Wet Bulb Global Temperature (WBGT) Outdoor Heat Stress monitor at 9:45 a.m. was 26.6 degrees. This advisory is in effect until June 7 at 1800 hrs.

The prevention measures to be taken to combat the effects of heat stress for individuals performing strenuous work are as follows (see chart below):

Values in this table are applicable to personnel wearing a single layer uniform with sleeves rolled up and without a helmet.

It applies to both men and women given comparable levels of fitness.

When wearing either CBRN protective clothing or body armour:

• Add 5°C to the WBGT value at the time

• If wearing either of these equipment, it is not safe to perform any activity listed under the category of “heavy activity” or “very heavy activity” or to run.

Adherence to these guidelines for water intake and work/rest cycles will go a long way to avoiding some of the unpleasant consequences of summer heat (i.e. heat cramps, heat exhaustion, etc).

Supervisors, in particular, should ensure that these guidelines are followed. For those exposed to the sun‘s direct rays, the use of a good sunscreen with a minimum Sun Protection Factor (SPF) of 15, is strongly recommended.
