Title 8 CCR 3396

Indoor heat is a serious workplace safety issue, especially in facilities where temperatures rise quickly due to equipment, poor ventilation, or seasonal weather. Under Cal/OSHA’s Heat Illness Prevention in Indoor Places of Employment standard, employers must take steps to protect workers from heat-related illness, including monitoring conditions and implementing preventive measures. That is where a WBGT-1000 series monitor becomes valuable. By measuring heat stress more accurately than ambient temperature alone, EnviroLive’s Cloud-Ready Heat Stress monitoring and alarm system helps employers identify hazardous conditions early and respond before workers are placed at risk.

What Cal/OSHA’s Indoor Heat Standard Means

Cal/OSHA’s indoor heat illness prevention rule applies to many indoor workplaces where heat exposure can become dangerous. The standard is designed to reduce the risk of heat exhaustion, heat stroke, dehydration, and other heat-related illnesses.

Employers are expected to provide:

  • Water

  • Cool-down areas

  • Rest breaks

  • Training on heat illness prevention

  • Emergency response procedures

  • Monitoring of indoor heat conditions

For many businesses, the challenge is not just knowing the rules, it is having the right tools to measure and manage heat stress effectively.

Why WBGT Is Important

WBGT, or Wet Bulb Globe Temperature, is one of the most useful ways to measure environmental heat stress. Unlike a basic thermometer, WBGT takes into account more than just air temperature.

A WBGT reading helps reflect:

  • Ambient temperature
  • Humidity
  • Radiant heat
  • Air movement

This makes the WBGT-1000 a much better indicator of whether workers are at risk from heat stress in real working conditions. For indoor facilities such as warehouses, manufacturing plants, distribution centers, and industrial shops, this level of detail is critical.

How the WBGT-1000 Series Supports Compliance

A heat stress monitoring device can help employers make faster, more informed decisions. When indoor temperatures rise, supervisors need a clear reading they can trust.

A WBGT-1000 monitor can help by:

  • Tracking indoor environmental conditions in real time
  • Supporting heat illness prevention programs
  • Helping supervisors know when to increase cooling measures
  • Providing data for safety records and planning
  • Supporting a proactive workplace safety culture

For employers trying to align with Cal/OSHA expectations, monitoring is a practical first step toward prevention.

EnviroLive’s WBGT-1000 Series

Consistent

By monitoring the thermal footprint of the production floor and external areas, the device ensures that every shift operates under the best environmental conditions.

Reliable

Captures a full profile of the production environment, ensuring warnings of relative humidity and radiant heat stay within strict parameters.

Accurate

The WBGT-1000 Series provides detailed temperature readings, including humidity and radiant heat from machinery, preventing ambient interference and possible thermal degradation.

Through real-time telemetry, data is streamed directly to the dashboard, allowing for instant oversight of the entire facility from the central office, or any personal device.

The transition to data-driven heat safety marks a shift in how we manage the modern industrial environment. With EnviroLive’s WBGT-1000 Series‘s ability to monitor every zone of your facility from any device, you gain the transparency needed to mitigate risks before they impact your bottom line. Protect your team, preserve your assets, and maintain your competitive edge with a smarter approach to environmental awareness.
