Breathing Easy Underground: Cooling and Comfort
for Workers in Extreme Heat

The Silent Hazard of Heat Stress

In industrial sites, safety teams often focus on visible hazards falling objects, live wires, chemical spills. But there’s one danger that creeps up quietly and drains workers of their energy, focus, and safety awareness: heat stress.

Whether it’s a miner in a confined tunnel, a construction worker on a scorching rooftop, or a welder inside a metal enclosure, extreme temperatures put immense strain on the body and mind.

According to the International Labour Organization (ILO), heat stress reduces worker productivity by up to 20% and increases the risk of fatigue-related accidents. In high-risk environments, comfort becomes a matter of survival.

Why Heat is More Dangerous Than It Looks

When body temperature rises beyond the safe range, the results can be serious:

  • Fatigue and dizziness leading to poor judgment
  • Dehydration and cramps that reduce focus
  • Heat exhaustion or heat stroke, which can be fatal if ignored

These effects multiply in enclosed or poorly ventilated spaces where airflow is limited. Traditional PPE often makes things worse by trapping heat instead of dissipating it.

That’s where smart ventilation comes into play.

ActivCooling™: Where Safety Meets Comfort

Jarsh’s ActivCooling™ Helmet is a breakthrough in personal comfort technology – a certified safety helmet equipped with built-in cooling and ventilation systems. Designed for extreme industrial conditions, it keeps workers alert, focused, and protected.

Key Features:

  • Internal and External Battery Variants: Choose between compact 2-hour internal battery or full-shift (8-hour) external battery options.
  • Cooling & Heating Functionality: Provides airflow and temperature regulation for both hot and cold environments.
  • Lightweight, Certified Protection: IS 2925 and EN 397 certified for impact resistance and safety compliance.
  • Comfort-Oriented Design: Adjustable fit, low noise, and available with clear or tinted visors.

From underground mines to outdoor construction sites, ActivCooling™ helps workers breathe easier – literally.

Real-World Impact: Mining and Heavy Construction Sites

In mining operations, ventilation systems can’t always reach every corner. Workers often face temperatures exceeding 40°C with minimal airflow. By wearing the ActivCooling™ Helmet, they receive direct airflow to the head, preventing heat buildup and fatigue.

Similarly, in heavy construction and shipyards, long exposure to sun and heat often leads to dehydration and early exhaustion. The ActivCooling™ system keeps body temperature stable, allowing workers to stay safe and productive through long shifts.

The Science of Focus and Safety

Studies show that even a 1°C increase in body temperature can reduce mental performance and decision-making accuracy. In high-risk industries, that’s a margin of error you can’t afford.

By maintaining body temperature and reducing discomfort, cooling helmets like ActivCooling™ don’t just protect workers from physical harm – they also improve reaction time, focus, and alertness.

Safety isn’t just about hard hats and checklists anymore. It’s about helping workers perform at their best in every condition.

 

Certified for Tough Environments

Every ActivCooling™ helmet meets global safety standards:

  • IS 2925 (India) – Industrial safety helmet certification.
  • EN 397 (Europe) – Shock absorption, resistance to penetration, and heat protection.
  • ISO 9001:2015 – Manufactured under strict quality controls.

It’s not just comfort gear – it’s certified protective equipment designed for the realities of the field.
