What is the latest update to the OSHA Heat Stress Standard?

An informal public hearing to provide an update on OSHAโ€™sย Heat Injury and Illness Prevention in Outdoor and Indoor Work Settingsย proposed rule is scheduled to be held virtually on June 16, 2025.

We all know the risk โ€“ and the stats. According to the Bureau of Labor Statistics, there were 33,890 estimated work-related heat injuries and illnesses between 2011-2020 that resulted in days away from work. Thatโ€™s an average of 3,389 injuries and illnesses per year โ€“ and those numbers are very likely vastly underestimated.

OSHAโ€™s proposed heat stress standard looks to address this threat by establishing a federal heat standard that will apply to all general industry, construction, maritime, and agriculture sectors where OSHA has jurisdiction. Public comment on the proposed rule closed on January 14, 2025 and OSHA has announced an informal public hearing on the proposed rule to be held virtually on June 16, 2025.

With temperatures rising across the country, proactive EHS programs arenโ€™t waiting for the new heat stress standard to keep their teams safe. The BIOKINETIX medical professionals are already working with clients to create formal Heat Illness Prevention Plans (HIIPP).

Components of a Heat Illness Prevention Plan (HIIPP):

  • On-Site Monitoring: Track heat index in real time and adjust tasks accordingly
  • Acclimatization Programs: Gradually introduce new or returning workers to heat-intensive roles
  • Hydration Protocols: Make water easily accessible and enforce scheduled hydration breaks
  • Environmental Modifications: Provide shade, fans, misting stations, and breathable PPE
  • Scheduled Rest Breaks: Implement mandatory cool-down periods during high-heat windows
  • Designate a Heat Safety Coordinator: Raise the importance of addressing these threats with team member(s) directly responsible for efforts

According to the National Athletic Trainersโ€™ Association (NATA), dehydration of just 1% to 2% of body weight begins to compromise physiological function and negatively influence performance. Dehydration of greater than 3% increases an industrial athleteโ€™s risk of developing a heat illness, i.e., heat cramps, heat exhaustion, or heat stroke.*

How we can help

Along with you, weโ€™ll be monitoring guidance on OSHAโ€™s heat stress standard from the June update. But with the threat of heat illness already impacting your team, now is the time to start a Heat Illness Prevention Plan (HIIPP) or optimize an existing one.

Letโ€™s talk about whatโ€™s working, what needs addressed differently, and how BIOKINETIX medical professionals can help make heat stress prevention an active part of your safety culture via early intervention, targeted education, and on-site expertise. Get in touch with us at info@biokinetix.com.
