Take precautions when working outdoors in high heat

The dog days of summer have arrived along with rising temperatures and increased heat-related health risks. If your work takes you outdoors under the beating sun, here are a few suggestions from the Occupational Safety and Health Administration(OSHA) for avoiding heat-related illness.

Exposure to heat can cause illness and death. The most serious heat illness is heat stroke. Other heat illnesses, such as heat exhaustion, heat cramps and heat rash, should also be avoided.

Risk factors for heat illness
• High temperature and humidity, direct sun exposure, no breeze or wind
• Low liquid intake; previous heat illnesses
• Heavy physical labor
• Waterproof clothing
• No recent exposure to hot workplaces

Symptoms of heat exhaustion
• Headache, dizziness, or fainting
• Weakness and wet skin
• Irritability or confusion
• Thirst, nausea, or vomiting

Symptoms of heat stroke
• May be confused, unable to think clearly, pass out, collapse, or have seizures (fits)
• May stop sweating

To prevent heat illness, your employer should:
• Provide training about the hazards leading to heat stress and how to prevent them.
• Provide a lot of cool water to workers close to the work area. At least one pint of water per hour is needed per person.
