Hand injuries can differ significantly depending on whether they occur in cold weather or warm/hot conditions. The variance is influenced by environmental factors, worker performance and physiological responses to temperature extremes. By proactively addressing risks specific to temperature extremes, workers can protect themselves from hand injuries and maintain productivity in challenging environments.
Common Cold Weather Risks:
• Frostbite: Prolonged exposure to cold can damage skin and tissues, especially on hands and fingers.
• Decreased Dexterity: Cold temperatures reduce blood flow, causing stiffness and loss of coordination, increasing the risk of mishandling tools or equipment.
• Numbness: Workers may not feel injuries or cuts immediately, delaying treatment.
• Chapping/Cracking: Dry air and cold can cause the skin to crack, leading to infection or worsened injuries.
• Reduced Grip Strength: Cold temperatures can cause muscles to fatigue more quickly, increasing the risk of dropping objects or tool mishaps.
Mitigation Measures:
• Use insulated gloves suited for the task.
• Schedule frequent breaks to warm up.
• Use hand warmers and protective barriers from wind and cold.
• Recognize early signs of frostbite and hypothermia.
General OSHA Recommendations:
• Conduct regular hand protection training.
• Provide task-specific PPE.
• Monitor environmental conditions and adjust schedules as needed.
• Conduct pre-shift inspections of equipment to ensure safety.
