Summer time is upon us. We wanted to share some workplace safety tips to ensure that everyone have a safe and enjoyable summer both at work and at play. Heat stress occurs when the body is unable to regulate itself by sweating and one’s core body temperature rises to critical levels. It is a medical emergency that can lead to heat cramps, heat exhaustion, heat stroke and in severe cases, death.
