motion, and common accidents on the job, will help workers understand the true risks of TBIs and increase PPE usage. The type of helmet that workers wear is almost as important as ensuring they are worn in the first place. Workers should guarantee that their helmets meet current safety standards. Additionally, they could consider helmets equipped with a rotational mitigating system, which is designed to help reduce the transmission of rotational motion to the wearer’s head in the case of certain angled impacts. There are a number of risks that workers face on the job, many of which aren’t expected to go away anytime soon. Therefore, education about rotational motion and TBIs and implementing best practices for safety measures and PPE usage is urgently needed to improve workplace safety. Sofia Hedenstierna works as Safety and Biomechanics expert at Mips focusing on occupational helmet safety in the construction industry. She has a PhD in Biomechanics from the Royal Institute of Technology from 2008 and has worked at the Swedish Defense Research Agency (FOI) with personal protection before joining the team at Mips in 2021. She has been a delegate to the European Committee for Standardization on head protection since 2021. REFERENCES 1. blogs.cdc.gov/niosh-science-blog/2016/03/21/constructiontbi/ 2.
