Cal/OSHA Heat Illness Prevention

Protecting Workers from Heat-Related Risks

Cal/OSHA Heat Illness Prevention Standards

California’s Division of Occupational Safety and Health (otherwise known as “Cal/OSHA”) recently implemented the “Heat Illness Prevention in Indoor Places of Employment” standards. Cal/OSHA’s new standard is a comprehensive set of regulations intended to protect both indoor and outdoor workers from the dangers of heat illness. Some important provisions of this standard include:

  • Heat Illness Prevention: Employers must provide water, shade, and periodic rest breaks when temperatures exceed certain thresholds.

  • Training Requirements: Employers are responsible for training workers on the dangers of heat illness and prevention techniques. Training must cover the importance of drinking water, recognizing signs of heat illness, and reporting symptoms early.

  • Emergency Procedures: Employers must establish and implement procedures to respond to heat illness and train employees on those procedures.

Cal/OSHA’s High-Heat Procedures: Ensuring Worker Safety

The “Heat Illness Prevention in Indoor Places of Employment” standards includes specific guidelines that apply to workplaces operating in high-heat conditions. High-heat procedures are meant to further protect workers during events with extreme heat. Key provisions of these procedures include:

  • Definition of High-Heat Conditions: Any workplace environment where temperatures exceed 95°F.

  • Supervisory Monitoring: Employers must have supervisors closely monitor employees for signs of heat illness.

  • Communication Protocols: Employers must ensure that workers can contact supervisors quickly if they experience heat-related issues.

  • Mandatory Rest Breaks: Employers must schedule rest breaks more frequently to prevent heat-related illnesses. 

  • Designated Cool-Down Zones: Easily accessible areas must be provided for workers to cool down during breaks.

Indoor Heat Illness Prevention Regulations

To protect employees working in hot indoor environments, Cal/OSHA introduced specific regulations focused on reducing heat-related risks indoors. The regulations pertaining to indoor workers are designed to address the dangers of heat exposure within enclosed spaces and protect worker safety. Some key requirements are:

  • Temperature Threshold: The indoor temperature threshold is set at 82°F.

  • Assessment and Control Measures: When indoor temperatures consistently reach or exceed the temperature threshold, employers are required to implement protective measures to prevent heat-related illnesses such as ventilation or air conditioning.

  • Acclimatization: Procedures must be in place to allow workers to adjust gradually to high-heat environments. Some acclimatization procedures include gradually increasing exposure time to high-heat conditions over a period of days, monitoring workers closely during initial high-heat exposure periods, providing additional rest breaks for new or returning employees, and supervising workers for signs of heat illness during an adjustment period.

High-Heat Procedures (87°F or Above)

When indoor temperatures reach 87°F or higher, employers must follow stricter safety measures to protect workers from heat illness:

  • Increased Monitoring: Supervisors have to closely watch employees for signs of heat illness, especially during high-heat periods.

  • Frequent Rest Breaks: Workers should be allowed to take more regular breaks to cool down and hydrate.

  • Enhanced Communication: Clear protocols must be in place for employees to report symptoms quickly and receive immediate assistance.

Cal/OSHA’s Employee Training and Emergency Response

Pursuant to the “Heat Illness Prevention in Indoor Places of Employment” standards, employers are required to train workers on how to prevent heat illness and respond to emergencies caused by heat exposure. Heat illness training helps employees understand how to stay safe and act quickly in dangerous situations. Comprehensive training touches on:

​

  • Risk Factors: Conditions that increase the likelihood of heat stress.

  • Preventative Measures: Importance of hydration, access to shade, and rest breaks.

  • Employer Responsibilities: What workers should expect from their employers regarding safety measures.

  • Recognizing Symptoms: Training on early signs of heat illness such as dizziness, fatigue, and nausea.

  • Emergency Procedures: An emergency response plan for heat illness should include immediate actions workers should take to cool down, clear procedures on how workers should notify supervisors and receive medical care quickly.

Recordkeeping and Compliance

Cal/OSHA mandates strict recordkeeping to make sure employers comply with heat illness prevention regulations. These records serve as proof of compliance and help track the implementation of safety measures. Some relevant records are:

  • Training Records: Documentation of all employee training sessions on heat illness prevention.

  • Written Heat Illness Prevention Plan (HIPP): A comprehensive plan detailing procedures for heat illness prevention, available for employee review.

  • Incident Reports: Employers must document any heat illness incidents, as well as responses to those incidents, to promote accountability

The Benefits of Compliance

Complying with Cal/OSHA's heat illness prevention standards offers multiple advantages for employers. These measures not only protect employees from heat-related risks but also help businesses avoid legal and financial challenges. Some of the key benefits include:

​

  • Improved Worker Safety: Preventive steps like hydration and rest breaks significantly lower the risk of heat illness.

  • Regulatory Adherence: Staying compliant prevents costly fines and penalties.

  • Lower Liability: Reduced workplace accidents lead to fewer legal claims.

  • Decreased Absenteeism: Healthier employees take fewer sick days.

  • Lower Workers' Compensation Costs: Fewer incidents mean reduced claims and expenses.

  • Enhanced Productivity: A safe, well-rested workforce performs more efficiently.

  • Boosted Morale: Employees feel more secure and valued when safety measures are prioritized

Practical Tips for Employers to Meet Heat Illness Prevention Standards

Employers can adopt specific measures to protect workers from heat-related illnesses. Simple actions, such as adjusting work schedules, increasing access to water, and creating cool-down areas, help maintain compliance with Cal/OSHA regulations while prioritizing employee safety.

  • Monitoring Heat Index: Use heat index monitoring tools to assess environmental risk levels throughout the workday.

  • Shift Scheduling: Adjust work schedules so that the most strenuous tasks are completed during the cooler hours of the morning or late afternoon to reduce the risk of heat illness.

  • Rotating Workers: Rotate employees to minimize the time each worker spends in highheat environments.

  • Frequent Breaks: Encourage regular rest breaks, especially in high-heat conditions.

  • Hydration Stations: Provide easy access to water throughout the worksite.

  • Air Conditioning and Ventilation: Implement effective cooling systems for indoor workplaces.

  • Buddy System: Implement a buddy system where workers monitor each other for signs of heat stress.

  • Heat Illness Audits: Regularly audit the worksite for compliance with all heat illness prevention measures.
