They account for nearly 60% of all injuries in 2023/24, according to a Freedom of Information request submitted by Hughes Safety Showers to the HSE.
The RIDDOR figures show that of the 740 injuries recorded last year related to hazardous substances, 438 were chemical burns, representing 59.19% of all incidents.
This marks a 6.57% increase in burns from the previous year, highlighting a need for continued vigilance.
Although overall injuries from harmful substances have decreased during the last decade, the recent uptick, a 12.9% rise in total cases in the past year, indicates that exposure risks remain prevalent across industries.
Experts are urging employers to reinforce best practices regarding chemical handling and invest in adequate protective equipment and emergency response infrastructure.
This includes the installation of emergency safety showers and eyewash stations, which play an important role in reducing the severity of chemical burns when incidents occur.
James Hamilton, Global Engineering Manager at Hughes Safety Showers, said: “The quicker a harmful substance is removed from the skin, the less damage it can do."
"Having compliant, well-maintained emergency decontamination equipment can mean the difference between a minor injury and a life-changing one.
In addition to physical safeguards, regular risk assessments and staff training on chemical spill procedures are essential in reducing incident rates and improving on-site response.
James said: “Despite long-term improvements in chemical safety, the recent increase in total injuries and burns is a clear reminder that complacency is not an option."
"With burns making up the majority of injuries linked to hazardous substances, employers must reassess their safety protocols, ensure compliance with industry standards and invest in fast-acting emergency equipment that can help mitigate harm.”
